S4025NTP

Overview

The Littelfuse S4025NTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx25x series, designed for surface mount applications in the SMTO-263-2 package. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 25 A. Key electrical parameters include a maximum non-repetitive peak on-state current of 350 A, a forward voltage of 1.6 V, and a gate trigger current of 35 mA. The device operates within a temperature range of -40°C to +125°C and includes UL recognition.

Feature Summary

Surface mount construction in an SMTO-263-2 package for automated PCB assembly
Sensitive gate design allowing direct interfacing with microprocessors
Glass passivated junctions for enhanced durability and reliability

Applications

Strobe light control circuits
Fluid level sensors
Capacitive-discharge ignition systems

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and thermal characteristics. Confirm RoHS compliance status and UL recognition details directly from the manufacturer datasheet before finalizing component selection for production.

Selection Notes

Select this SCR for high-current switching where low gate drive power is required. Ensure the circuit can handle the 350 A surge capability and that the operating temperature remains within the specified -40°C to +125°C range for reliable performance.

Part Context

This component belongs to the Littelfuse Teccor Sxx25x family of SCRs. These devices are engineered for efficient switching in low-current control circuits, offering fast turn-off capabilities to reduce commutation failure risks in demanding electronic controls.

Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or thermal resistance; verify all critical parameters against the original datasheet.
