Overview
The Littelfuse S602ES1 is a Silicon Controlled Rectifier (SCR) belonging to the Sx02xS series, designed for through-hole mounting in a TO-92-3 package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (It RMS) of 1.5 A. Key electrical parameters include a maximum holding current (Ih) of 3 mA, a forward voltage drop (Vf) of 1.7 V, and a gate trigger voltage (Vgt) of 800 mV with a gate trigger current (Igt) of 100 uA. The device exhibits a low off-state leakage current of 5 uA at VDRM and supports a non-repetitive on-state peak current of 15 A. It operates within a temperature range of -40 C to +125 C.
Feature Summary
- Provides reliable switching capability for AC power control applications with high voltage blocking.
Applications
- General purpose AC power switching circuits
- Lighting control systems
- Motor speed control interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and variant selection. Confirm that the TO-92-3 through-hole package aligns with the target PCB layout requirements. Check for any recent product change notifications or end-of-life notices from Littelfuse before finalizing procurement plans.
Selection Notes
Select this component when a 600 V blocking voltage and 1.5 A continuous current rating are required in a compact through-hole form factor. Ensure the driving circuit can supply at least 100 uA at 800 mV for reliable triggering. Consider thermal management capabilities given the 125 C maximum junction temperature limit and the small TO-92-3 package size.
Part Context
The S602ES1 is part of Littelfuse's Sx02xS family of silicon controlled rectifiers. This series offers standardized electrical characteristics across various packages, allowing designers to swap between through-hole and surface-mount options while maintaining consistent performance metrics for power control applications.
Replacement Considerations
Consult Littelfuse documentation for direct pin-compatible alternatives within the Sx02xS series. Verify that any substitute SCR matches the 600 V VDRM, 1.5 A It RMS, and TO-92-3 package specifications to ensure functional equivalence.
