Scrs datasheet and documents for S4012RTP

S4012RTP

Scrs Overview

The Littelfuse S4012RTP is a silicon-controlled rectifier (SCR) from the Sxx12x series, designed for through-hole mounting in TO-220-2 packages. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 12 A. The device has a maximum gate trigger voltage of 1.5 V and a gate trigger current of 20 mA. Forward voltage is 1.6 V, with a holding current maximum of 40 mA. Leakage current at VDRM is 10 uA. Non-repetitive peak on-state current is 120 A. Operating temperature ranges from -40 C to +125 C. It carries UL compliance.

Scrs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package type matches TO-220-2 specifications. Ensure operating conditions stay within the -40 C to +125 C range. Validate electrical parameters like 400 V blocking voltage and 12 A current rating against circuit requirements before integration.

Scrs Selection Notes

Select this SCR when through-hole assembly is required for 12 A loads at 400 V. Compare gate sensitivity requirements against the 20 mA trigger current specification. Consider thermal management needs given the TO-220-2 package size. Verify compatibility with existing PCB layouts designed for standard through-hole thyristor footprints.

Scrs Part Context

This part belongs to the Littelfuse Sxx12x series of SCRs. It shares core electrical characteristics with other variants in the family but differs in packaging and termination style. The S4012RTP specifically denotes the tube-packaged through-hole version, distinct from surface-mount alternatives like the S4012DRP.

Scrs Replacement Considerations

S4012R is the base part number for this component. Verify pinout compatibility when substituting with equivalent SCRs from other manufacturers. Ensure replacement parts meet the same 400 V and 12 A ratings.
