Overview
The Littelfuse S802CS1RP is a silicon-controlled rectifier (SCR) from the Sx02CSx series, designed for surface-mount applications in the Compak package. It features a sensitive gate structure with a maximum repetitive off-state voltage of 800 V and an on-state RMS current rating of 1.25 A. The device operates within a junction temperature range of -40°C to 110°C. Key electrical parameters include a maximum gate trigger voltage of 800 mV, a maximum gate trigger current of 200 µA, and a maximum on-state voltage of 1.7 V. The non-repetitive peak surge current capacity is rated at 16 A for 50 Hz and 20 A for 60 Hz frequencies.
Feature Summary
- Sensitive gate architecture enabling low-power triggering requirements
- Surface-mount Compak packaging optimized for automated PCB assembly
- High-voltage blocking capability suitable for demanding power circuits
Applications
- AC power control systems
- Solid-state relays
- Motor speed control circuits
Procurement Notes
Verify the specific suffix 'S' against official Littelfuse documentation to confirm exact binning or testing variations. Ensure the ordering code matches the required tape-and-reel or cut-tape configuration. Cross-reference the component marking with the manufacturer's datasheet to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a high-voltage SCR is required in a compact surface-mount form factor. The sensitive gate characteristic simplifies drive circuit design by reducing the necessary trigger current. Verify that the 1.25 A RMS current rating meets the load requirements and that the 800 V voltage rating provides adequate margin for the application's peak reverse voltage.
Part Context
This device belongs to the Sx02CSx family of sensitive gate SCRs manufactured by Littelfuse. These components are engineered for reliability in industrial and consumer electronics. The Compak package allows for efficient space utilization on printed circuit boards compared to traditional through-hole alternatives.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or thermal characteristics. Validate any alternative part against the original specifications for voltage, current, and package dimensions.
