Overview
The TCET1102G is a single-channel phototransistor output optocoupler from Vishay, designed for high-temperature applications. It features a 4-DIP (7.62mm) through-hole package with 5000Vrms isolation voltage. Key electrical parameters include a maximum collector-emitter voltage of 70V and a peak forward current of 60mA. The typical forward voltage is 1.25V, with a collector-emitter saturation voltage of 300mV max. Current transfer ratio ranges from 63% to 125% at 10mA input. Operating temperatures span -40°C to +100°C, with turn-on/turn-off times of 6μs and 5μs respectively.

Procurement Notes
Verify the specific CTR bin (63%-125%) required for your application against datasheet specifications. Confirm DIP-4 package dimensions match PCB layout requirements. Check RoHS compliance status if restricted substances are a concern. Ensure operating temperature range meets system thermal conditions. Validate isolation voltage ratings against safety standards applicable to your end product.
Selection Notes
Select this component when high-temperature stability and robust isolation are required. Consider the 63-125% CTR range for signal integrity needs. Evaluate the 70V output voltage limit for load compatibility. Compare timing characteristics (6μs/5μs) against signal speed requirements. Assess DIP-4 packaging constraints for assembly processes.
Part Context
Part of Vishay's TCET1100 series of transistor-output optocouplers. Designed specifically for high-temperature industrial applications. Utilizes standard 4-DIP packaging for easy integration into existing designs. Offers reliable performance across wide temperature ranges suitable for demanding environments.
Replacement Considerations
TCET1104G, TCET1106G, TCET1108G are alternative variants within the same series offering different CTR ranges. Verify pinout compatibility before substitution. Confirm isolation voltage and temperature ratings meet or exceed original requirements.
