Overview
The TCET1107G is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and operates within a temperature range of -40°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward current rating of 60 mA. The device provides an insulation voltage of 5000 Vrms and exhibits a current transfer ratio ranging from 80% to 160%. Additional specifications include a forward voltage of 1.6 V, a reverse voltage of 6 V, power dissipation of 265 mW, and switching times of 3 µs rise and 4.7 µs fall.
Feature Summary
- Provides high-voltage isolation with 5000 Vrms insulation capability between input and output circuits.
- Utilizes an NPN phototransistor output for reliable signal transmission in digital applications.
- Designed for through-hole mounting in standard PDIP-4 packages for easy integration into PCB layouts.
Applications
- General-purpose digital signal isolation
- Microcontroller interface circuits
- Switching power supply feedback loops
Procurement Notes
Verify the specific suffix 'G' corresponds to RoHS compliance requirements when sourcing. Confirm that the PDIP-4 package matches the target footprint on the printed circuit board. Ensure the operating environment stays within the specified -40°C to +100°C temperature range to maintain performance integrity. Cross-reference the manufacturer datasheet for any recent updates regarding pinout configurations or absolute maximum ratings before finalizing the design.
Selection Notes
Select this component when a single channel of isolation with moderate current transfer ratio is required. The 80-160% CTR range offers flexibility for various logic levels. Consider the 5000 Vrms isolation rating for safety-critical applications. The through-hole PDIP-4 format is suitable for prototyping or environments requiring robust mechanical stability compared to surface-mount alternatives.
Part Context
This part belongs to the TCET series of transistor output optocouplers from Vishay. It shares common characteristics with siblings like TCET1106G and TCET1108G, differing primarily in the current transfer ratio specifications. The series is designed for general-purpose isolation tasks where cost-effectiveness and standard packaging are prioritized over high-speed or specialized output types.
Replacement Considerations
TCET1106G (CTR 100-300%), TCET1108G (CTR 130-260%)
