S2012DTP

Scrs Overview

The Littelfuse S2012DTP is a silicon-controlled rectifier (SCR) from the Sxx12x series, designed for surface-mount applications in TO-252-3 packages. It features an RMS on-state current of 12 A and a rated repetitive peak off-state voltage of 800 V. The device supports a non-repetitive peak on-state current of 120 A with a maximum holding current of 40 mA. Electrical characteristics include a forward voltage of 1.6 V, gate trigger voltage of 1.5 V, and gate trigger current of 20 mA. Leakage current is limited to 10 uA at VDRM. Operating temperatures range from -40 C to +125 C.

Scrs Feature Summary

• Surface-mount construction in a TO-252-3 package for automated PCB assembly
• High thermal stability supporting operation up to 125 C junction temperature
• Robust surge handling capability with 120 A non-repetitive peak current rating

Scrs Applications

• Industrial motor control circuits
• AC power switching systems
• Solid-state relay implementations

Scrs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse before finalizing procurement. Confirm that the TO-252-3 package dimensions match the target PCB footprint requirements. Ensure the 800 V voltage rating aligns with the system's peak off-state voltage demands to prevent premature breakdown during operation.

Scrs Selection Notes

Select this component when a high-current SCR is required in a compact surface-mount form factor. The 12 A RMS rating suits moderate power loads where through-hole alternatives are impractical. Verify that the 800 V blocking voltage exceeds the circuit's maximum transient voltages. Consider the 1.5 V gate trigger requirement for compatible driver interface design.

Scrs Part Context

This part belongs to the Littelfuse Sxx12x family of thyristors, which standardizes the 12 A current rating across various voltage classes. The 'S' prefix denotes Silicon Controlled Rectifiers, while '12' indicates the 12 Ampere RMS current capacity. The suffix 'TP' specifies the tube packaging format for the TO-252-3 case style.

Scrs Replacement Considerations

Cross-reference with other Sxx12x series variants such as S8012DTP or S4012DRP if different voltage ratings are acceptable. Verify pinout compatibility and thermal resistance values when substituting with equivalent SCRs from other manufacturers.
