Overview
The S802TSRP is a Silicon-Controlled Rectifier (SCR) manufactured by Littelfuse Inc., designed for surface-mount applications. It features an SOT-223-3 package and operates with a blocking voltage rating of 800 V. The device supports an on-state current of 2 A, making it suitable for low-current switching circuits. Key electrical parameters include a maximum gate trigger current of 10 mA and a turn-off time below 55 µs. The component is RoHS compliant and utilizes glass passivation for junction durability.
Feature Summary
- Surface-mount construction in a compact SOT-223-3 package
- High blocking voltage capability for robust circuit protection
- Sensitive gate design allowing direct interfacing with microprocessors
- Glass-passivated junction for enhanced environmental durability
Applications
- Capacitive-discharge ignition systems
- Fluid level sensors
- Strobe light control circuits
Procurement Notes
Verify the specific ordering suffix to ensure the correct packaging configuration, such as cut tape or reel, matches the assembly requirements. Confirm that the 800 V rating and 2 A current capacity align with the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount SCR with high voltage blocking capability is required. Ensure the application demands a sensitive gate drive compatible with standard logic levels. Verify thermal management needs for the SOT-223 package under continuous operating conditions.
Part Context
This part belongs to the Littelfuse discrete SCR family, which offers various voltage and current ratings for power control applications. The S802TSRP specifically addresses the need for high-voltage switching in compact form factors, complementing other series like the S6002xS for different voltage tiers.
Replacement Considerations
Check for equivalent SCRs in the SOT-223 package with matching 800 V and 2 A ratings. Verify gate trigger characteristics and turn-off times to ensure functional compatibility in existing designs.
