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.

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.

OZONE DEPLETING SUBSTANCES POLICY STATEMENT
It is the policy of Vishay Semiconductor GmbH to
1. 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.
