Overview
The Littelfuse S8012NRP is a standard recovery silicon controlled rectifier (SCR) designed for surface mount applications. It features an 800 V repetitive peak off-state voltage and a 12 A RMS on-state current rating. The device operates within a junction temperature range of -40°C to +125°C. Key electrical characteristics include a maximum gate trigger voltage of 1.5 V and a gate trigger current of 20 mA. The component utilizes a D2PAK-2 package, providing robust performance for phase control circuits requiring reliable switching capabilities.
Feature Summary
- Standard recovery thyristor construction optimized for phase control applications
- Surface mount D2PAK-2 package design for automated assembly integration
- High thermal stability supporting operation up to 125°C junction temperature
Applications
- Phase control applications in heating systems
- Motor speed control circuits
- General purpose AC power switching
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required voltage and current ratings. Confirm that the D2PAK-2 package dimensions align with the target PCB footprint. Cross-reference the gate trigger parameters with the driving circuit specifications to guarantee reliable turn-on under all operating conditions.
Selection Notes
Select this component when a surface mount SCR with 800V blocking capability and 12A continuous current handling is required. Ensure the application does not exceed the non-repetitive surge current limits specified in the datasheet. Validate that the gate drive circuit can supply the necessary trigger current at the minimum operating temperature.
Part Context
This part belongs to the Littelfuse Sxx12x series of SCRs, which are engineered for low-power phase control duties. The series offers various voltage ratings while maintaining consistent current handling and package styles. These devices serve as unidirectional switches in AC power management systems where compact surface mount solutions are preferred over through-hole alternatives.
Replacement Considerations
Consult the Littelfuse official substitution guide for verified equivalent parts. Ensure any substitute matches the 800V Vdrm, 12A It rms, and D2PAK-2 package constraints. Generic replacements may differ in gate sensitivity or thermal resistance.
