S4035JTP

Scrs Overview

The Littelfuse S4035JTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx65x series, designed for high-reliability applications. It features an isolated flange mount in a TO-218X package with three pins. Key electrical parameters include a rated repetitive peak off-state voltage of 400 V and an on-state RMS current of 35 A. The device has a maximum gate trigger voltage of 1.5 V and a maximum gate trigger current of 40 mA. It supports a non-repetitive peak on-state current of 500 A and maintains operation within a temperature range of -40°C to +125°C.

Scrs Feature Summary

• Isolated flange mount construction for efficient thermal management
• High reliability design suitable for demanding industrial environments
• Robust surge current handling capability for transient protection

Scrs Applications

• Industrial motor control systems
• AC power switching circuits
• General purpose rectification

Scrs Procurement Notes

Verify the specific suffix 'JTP' against official Littelfuse documentation to confirm pinout, packaging, and compliance details. Ensure the procurement channel provides valid traceability for this through-hole component. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before ordering.

Scrs Selection Notes

Select the S4035JTP when a 400 V blocking voltage and 35 A continuous current rating are required in a TO-218X package. Compare its 500 A surge capacity against circuit fault conditions. Verify that the 1.5 V gate trigger voltage aligns with the driving logic levels available in the target application design.

Scrs Part Context

This component belongs to the Littelfuse Teccor Sxx65x family of SCRs. These devices are engineered for general-purpose power control tasks. The S4035JTP specifically offers a balance of moderate current handling and standard voltage ratings, making it a common choice for replacing older discrete thyristors in established electronic designs requiring reliable switching performance.

Scrs Replacement Considerations

Check for direct substitutes within the same Littelfuse series or equivalent offerings from other manufacturers. Ensure any replacement matches the TO-218X footprint, 400 V rating, and 35 A current capacity. Verify that the gate characteristics and thermal resistance are compatible with the existing heat sink design.
