Overview
The Littelfuse S602ECSRP is a silicon-controlled rectifier (SCR) from the Sx02xS series, designed for sensitive gate triggering applications. It features a rated repetitive off-state voltage of 600 V and an on-state RMS current of 1.5 A. The device operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current of 3 mA, a forward voltage of 1.7 V, and a gate trigger voltage of 800 mV with a gate trigger current of 100 uA. It is housed in a TO-92-3 package.
Feature Summary
- Sensitive gate structure enabling reliable triggering with low gate current requirements.
- High thermal stability supporting operation up to 125°C junction temperature.
- Robust off-state blocking capability suitable for standard AC line voltages.
Applications
- Lighting control circuits
- Motor speed regulation systems
- Solid-state relay inputs
Procurement Notes
Verify the specific suffix 'EC' against official Littelfuse documentation to confirm exact packaging or variant specifications, as distributor listings may vary. Ensure the component matches the required TO-92-3 through-hole configuration for your design. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement.
Selection Notes
Select this component when a 600V, 1.5A SCR with sensitive gate sensitivity is required in a TO-92 package. Compare the 100 uA gate trigger current against circuit drive capabilities. Ensure the 3 mA holding current aligns with load requirements to prevent unintended turn-off during operation.
Part Context
This part belongs to the Littelfuse Sx02xS family of thyristors, which are optimized for general-purpose switching and control applications. The S602 series specifically addresses needs for moderate current handling with high voltage blocking in compact through-hole packages.
Replacement Considerations
Compatible substitutes within the same series include S602ES1 and S602CSRP, provided they meet the identical 600V/1.5A/TO-92-3 specifications. Verify pinout compatibility and thermal characteristics before substitution.
