BRT21/BRT22/BRT23 Vishay Semiconductors Optocoupler, Phototriac Output, Zero Crossing FEATURES A 1 6 MT2 C 2 5 NC 3 17223 ZCC* NC 4 MT1 *Zero Crossing Circuit DESCRIPTION The BRT21, BRT22, BRT23 product family consists of AC switch optocouplers with zero voltage detectors with two electrically insulated lateral power ICs which integrate a thyrister system, a photo detector and noise suppression at the output and an IR GaAs diode input. High input sensitivity is achieved by using an emitter follower phototransistor and a SCR predriver resulting in an LED trigger current of less than 2 mA or 3 mA (DC). Inverse parallel SCRs provide commutating dV/dt greater than 10 kV/µs. The zero cross line voltage detection circuit consists of two MOSFETS and a photodiode. The BRT21/22/23 product family isolates low-voltage logic from 120, 230, and 380 VAC lines to control resistive, inductive or capacitive loads including motors, solenoids, high current thyristers or TRIAC and relays. • High input sensitivity IFT = 1.0 mA • ITRMS = 300 mA • High static dV/dt 10 000 V/µs • Electrically insulated between input and output circuit • Microcomputer compatible • Trigger current - (IFT < 1.2 mA) BRT22F, BRT23F, - (IFT < 2 mA) BRT21H, BRT22H, BRT23H - (IFT < 3 mA) BRT21M, BRT22M, BRT23M • Available surface mount and on on tape and reel • Zero voltage crossing detector • UL file E52744 system code J • DIN EN 60747-5-5 available with option 1 • Lead (Pb)-free component • Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC APPLICATIONS • Industrial controls • Office equipment • Consumer appliances ORDER INFORMATION PART REMARKS BRT21H VDRM ≤ 400 V, DIP-6, IFT = 2.0 mA BRT21M VDRM ≤ 400 V, DIP-6, IFT = 3.0 mA BRT22F VDRM ≤ 600 V, DIP-6, IFT = 1.2 mA BRT22H VDRM ≤ 600 V, DIP-6, IFT = 2.0 mA BRT22M VDRM ≤ 600 V, DIP-6, IFT = 3.0 mA BRT23F VDRM ≤ 800 V, DIP-6, IFT = 1.2 mA BRT23H VDRM ≤ 800 V, DIP-6, IFT = 2.0 mA VDRM ≤ 800 V, DIP-6, IFT = 3.0 mA BRT23M VDRM ≤ 400 V, DIP-6 400 mil (option 6), IFT = 2.0 mA BRT21H-X006 BRT21H-X007 VDRM ≤ 400 V, SMD-6 (option 7), IFT = 2.0 mA BRT21M-X006 VDRM ≤ 400 V, DIP-6 400 mil (option 6), IFT = 3.0 mA BRT22F-X006 VDRM ≤ 600 V, SMD-6 (option 7), IFT = 1.2 mA BRT22H-X007 VDRM ≤ 600 V, SMD-6 (option 7), IFT = 2.0 mA BRT22M-X006 VDRM ≤ 600 V, DIP-6 400 mil (option 6), IFT = 3.0 mA BRT23F-X006 VDRM ≤ 800 V, DIP-6 400 mil (option 6), IFT = 1.2 mA BRT23F-X007 VDRM ≤ 800 V, DIP-6 400 mil (option 6), IFT = 1.2 mA BRT23H-X006 VDRM ≤ 800 V, DIP-6 400 mil (option 6), IFT = 2.0 mA BRT23H-X007 VDRM ≤ 800 V, SMD-6 (option 7), IFT = 2.0 mA BRT23M-X006 VDRM ≤ 800 V, DIP-6 400 mil (option 6), IFT = 3.0 mA BRT23M-X007 VDRM ≤ 800 V, SMD-6 (option 7), IFT = 3.0 mA Note For additional information on the available options refer to option information.

POWER FACTOR CONSIDERATIONS www.vishay.com 196 1 Cs - Shunt Capacitance (µF) A snubber is not needed to eliminate false operation of the TRIAC driver because of the high static and commutating dV/dt with loads between 1.0 and 0.8 power factors. When inductive loads with power factors less than 0.8 are being driven, include a RC snubber or a single capacitor directly across the device to damp the peak commutating dV/dt spike. Normally a commutating dV/dt causes a turning-off device to stay on due to the stored energy remaining in the turning-off device. But in the case of a zero voltage crossing optotriac, the commutating dV/dt spikes can inhibit one half of the TRIAC from turning on. If the spike potential exceeds the inhibit voltage of the zero cross detection circuit, half of the TRIAC will be heldoff and not turn-on. This hold-off condition can be eliminated by using a snubber or capacitor placed directly across the optotriac as shown in Figure 1. Note that the value of the capacitor increases as a function of the load current. The hold-off condition also can be eliminated by providing a higher level of LED drive current. The higher LED drive provides a larger photocurrent which causes the phototransistor to turn-on before the commutating spike has activated the zero cross network. Figure 2 shows the relationship of the LED drive for power factors of less than 1.0. The curve shows that if a device requires 1.5 mA for a resistive load, then 1.8 times 2.7 mA) that amount would be required to control an inductive load whose power factor is less than 0.3.

Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs). The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively. 2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency (EPA) in the USA. 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay Semiconductors products for any unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
