Overview
The TCDT1100G is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output housed in a 6-pin PDIP package for through-hole mounting. The device provides 5000 Vrms isolation voltage and supports a maximum collector-emitter voltage of 32 V with a peak collector current of 50 mA. Key electrical parameters include a forward voltage of 1.6 V, a minimum current transfer ratio of 40%, and switching times of 7 µs rise and 6.7 µs fall. It operates within a temperature range of -40°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via optical coupling.
- Utilizes an NPN phototransistor output stage for reliable signal transmission.
- Designed for through-hole PCB integration using a standard 6-DIP package.
- Complies with RoHS directives for lead-free manufacturing standards.
Applications
- General-purpose signal isolation in industrial control systems
- Power supply feedback loops requiring galvanic separation
- Microcontroller interface circuits for noise immunity
- Solid-state relay driver applications
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance when sourcing. Confirm the 6-DIP package dimensions match your PCB footprint requirements. Ensure the 5000 Vrms isolation rating meets your safety certification needs. Cross-reference the datasheet for absolute maximum ratings to prevent over-stress during operation.
Selection Notes
Select this component when a single channel with moderate speed and high isolation voltage is required. Compare the 40% minimum CTR against circuit gain requirements. Consider the 32 V collector voltage limit for load compatibility. Evaluate the 6-DIP package size against available board space constraints.
Part Context
The TCDT1100G belongs to Vishay's TCET/TCDT series of phototransistor output optocouplers. This family offers various current transfer ratios and packaging options. The TCDT variant specifically denotes the transistor output configuration. It serves as a standard solution for basic isolation tasks in consumer and industrial electronics.
Replacement Considerations
Check for direct pin-compatible substitutes from Vishay such as other members of the TCET1100 series. Verify that alternative parts meet or exceed the 5000 Vrms isolation and 32 V collector voltage specifications. Ensure the replacement maintains the same 6-DIP package form factor for seamless integration.
