Overview
The S8X5ECS2RP is a silicon-controlled rectifier (SCR) from Littelfuse, belonging to the EV Series. It features an 800 V rated repetitive off-state voltage and an RMS on-state current of 0.8 A. The device utilizes sensitive gate triggering with a maximum gate trigger current of 50 uA and a gate trigger voltage of 800 mV. Packaged in a TO-92 through-hole case, it operates within a temperature range of -40 C to +125 C. Key electrical parameters include a holding current of 5 mA, a forward voltage of 1.7 V, and a non-repetitive peak on-state current of 10 A.
Feature Summary
- Sensitive gate control for low-power triggering applications
- High voltage blocking capability for robust circuit protection
- Through-hole mounting for reliable PCB integration
Applications
- AC power control circuits
- Lighting dimmer systems
- Motor speed control interfaces
Procurement Notes
Verify the specific manufacturer part number against official Littelfuse documentation to confirm availability and exact specifications. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as indicated in the component datasheet. Cross-reference the RoHS and REACH compliance status with the latest regulatory filings before finalizing procurement orders.
Selection Notes
Select this component when a high-voltage SCR with sensitive gate drive requirements is necessary. The 0.8 A current rating suits moderate load applications. Verify that the TO-92 package fits the mechanical constraints and that the thermal management supports the specified operating temperature range. Confirm compatibility with the gate driver circuit's output capabilities.
Part Context
This SCR belongs to the EV Series, designed for general-purpose switching. It complements other Littelfuse thyristors by offering a balance of voltage handling and sensitive gate sensitivity. The series targets cost-effective solutions for consumer electronics and industrial control panels requiring reliable AC switching performance.
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 electrical limits to ensure circuit safety and functionality are maintained without modification.
