S6025L

Overview

The S6025L is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, designed for high-power switching applications. It features a TO-220L package with three leads and supports through-hole mounting. The device has a repetitive peak reverse voltage of 600 V and an average on-state current rating of 25 A. It can withstand a surge current of 350 A at 60 Hz. The maximum gate trigger current is 10 mA, with a maximum gate trigger voltage of 1.5 V. The holding current is 35 mA. Operating temperatures range from -40°C to 150°C.

Feature Summary

• Glass-passivated junctions ensure long-term device reliability and parameter stability.
• Sensitive gate design allows for direct interfacing with microprocessors using minimal gate current.
• Electrically isolated TO-220L package eliminates the need for external insulators during installation.

Applications

• Strobe lights
• Fluid level sensors
• Capacitive-discharge ignition systems

Procurement Notes

Verify the specific suffix in the part number against official Littelfuse documentation to confirm exact electrical characteristics and packaging options. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Confirm RoHS compliance status if required for the target assembly process. Check for any automotive or industrial certifications relevant to the end application.

Selection Notes

Select this component when a robust SCR with 600 V blocking capability and 25 A continuous current handling is required. The sensitive gate characteristic simplifies driver circuit design compared to standard gate devices. Consider the thermal management requirements associated with the TO-220L package for the expected load conditions. Verify that the 350 A surge rating meets the transient demands of the specific circuit topology.

Part Context

This device belongs to the SVxx25xx series of silicon-controlled rectifiers from Littelfuse. The series offers various voltage ratings up to 600 V dc and surge capabilities tailored for efficient switching in low-current control circuits. These devices are engineered for precise operation and feature fast turn-off times to reduce commutation failure risks in demanding electronic controls.

Replacement Considerations

Cross-reference with SV6025L2TP for verified equivalent specifications including 600 V, 25 A, and TO-220L packaging. Ensure substitute parts match the gate trigger current limits and thermal characteristics to maintain circuit performance without redesign.
