The TRIAC consists of two inverse parallel connected monolithic SCRs. These three semiconductors are assembled in a six pin 0.3 inch dual in-line package, using high insulation double molded, over/under leadframe construction. Package Storage Temperature................... –55°C to +150°C Operating Temperature ............... –55°C to +100°C Lead Soldering Temperature.............. 260°C/5 sec. Isolation Test Voltage......................... 5300 VACRMS The IL420 uses two discrete SCRs resulting in a commutating dV/dt of greater than 10KV/ms. The use of a proprietary dv/dt clamp results in a static dV/dt of greater than 10KV/ms. This clamp circuit has a MOSFET that is enhanced when high dV/dt spikes occur between MT1 and MT2 of the TRIAC. When conducting, the FET clamps the base of the phototransistor, disabling the first stage SCR predriver. High input sensitivity is achieved by using an emitter follower phototransistor and a cascaded SCR predriver resulting in an LED trigger current of less than 2 mA (DC). The 600 V blocking voltage permits control of off-line voltages up to 240 VAC, with a safety factor of more than two, and is sufficient for as much as 380 VAC. The IL420 isolates low-voltage logic from 120, 240, and 380 VAC lines to control resistive, inductive, or capacitive loads including motors, solenoids, high current thyristors or TRIAC and relays. Applications include solid-state relays, industrial controls, office equipment, and consumer appliances. 5–1 Characteristics Symbol Min Typ Max Unit Condition Emitter Forward Voltage VF 1.16 1.35 V IF=10 mA Reverse Current IR 0.1 10 µA VR=6 V Capacitance CO 40 pF VF=0 V, f=1 MHz Thermal Resistance, Junction to Lead RTHJL 750 °C/W Output Detector Off-State Voltage VD (RMS) 424 460 V ID(RMS)=70 µA Reverse Voltage VR 424 460 V IR(RMS)=70 µA Off-State Current ID (RMS) 10 100 µA VD=600 V, TA=100°C Reverse Current IR (RMS) 10 100 µA VR=600 V, TA=100°C On-State Voltage VTM 1.7 3 V IT=300 mA On-State Current ITM 300 mA PF=1.0, VT(RMS)=1.7 V Surge (Non-Repititive) On-State Current ITSM 3 A f=50 Hz Holding Current IH 65 500 µA Latching Current IL 5 LED Trigger Current IFT 1 Turn-On Time tON Turn-Off Time tOFF mA VT=2.2 V mA VAK=5 V 35 µs VRM=VDM=424 VAC 50 µs PF=1.0, IT=300 mA 2 Critical State of Rise of Off-State Voltage Critical Rate of Rise of Voltage at Current Commutation dv/dtcr dv/dtcr 10000 5000 V/µs V/µs VD=0.67 VDRM Tj=25°C Tj=80°C dv/dtcrq dv/dtcrq 10000 5000 V/µs V/µs VD=0.67 VDRM, di/dtcrq≤15 A/ms Tj=25°C Tj=80°C 8 A/µs Critical State of Rise of On-State Current di/dtcr Thermal Resistance, Junction to Lead RTHJL 150 °C/W Critical Rate of Rise of Coupled Input/Output Voltage dv(IO)/dt 5000 V/µs Common Mode Coupling Capacitor CCM 0.01 pF Package Capacitance CIO 0.8 pF f=1 MHz, VIO=0 V Isolation Test Voltage, Input-Output VISO 5300 VACRMS Relative Humidity ≤50% Creepage ≥7 mm Clearance ≥7 mm Creepage Tracking Resistance per DIN IEC 112/VDE 0303, Part 1 group IIIa per DIN VDE 0110 CTI Insulation and Isolation IT=0 A, VRM=VDM=424 VAC 175 Isolation Resistance Ris Ris ≥1012 ≥1011 Trigger Current Temperature Gradient ∆IFT/∆Tj 7 Capacitance Between Input and Output Circuit CIO Ω Ω 14 µA/K 2 pF VIO=500, TA=25°C VIO=500, TA=100°C VR=0, f=1 kHz IL420 5–2 Figure 4.
