S6002TSRP

Overview

The Littelfuse S6002TSRP is a sensitive gate silicon-controlled rectifier (SCR) from the EV Series, housed in a surface-mount SOT-223 package. It features a repetitive peak off-state voltage of 600 V and an on-state RMS current rating of 2 A at a case temperature of 95 °C. The device supports a non-repetitive surge peak on-state current of 25 A at 60 Hz and offers a critical rate of rise of on-state current capability of 500 A/µs. Electrical characteristics include a maximum DC gate trigger current of 200 µA and a maximum holding current of 5 mA. The component operates within a virtual junction temperature range of -40 °C to 125 °C.

Feature Summary

• Sensitive gate architecture enables direct interfacing with microprocessors using minimal gate current.
• High di/dt capability of 500 A/µs ensures reliable switching during rapid current transitions.
• Glass-passivated junction construction provides long-term reliability and parametric stability.
• RoHS compliant and halogen-free manufacturing meets environmental standards.

Applications

• Capacitor discharge ignition systems
• High-power gas flame ignition circuits
• Strobe light triggering

Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm the SOT-223 surface mount package configuration. Confirm that the procurement channel sources genuine components directly from authorized distributors or the manufacturer to ensure compliance with RoHS and halogen-free specifications. Cross-reference the part marking with datasheet diagrams to validate authenticity upon receipt.

Selection Notes

Select this component for applications requiring high surge current handling and fast turn-off times below 55 µs. Ensure the design accommodates the thermal resistance requirements, specifically the junction-to-case value of 15 K/W for the SOT-223 package. Verify that the gate drive circuit can supply the necessary 200 µA trigger current while respecting the peak gate current limits under all operating conditions.

Part Context

This device belongs to the S6002xS series, which includes variants in TO-92 and Compak packages. The 'T' designation in the model number specifically identifies the SOT-223 surface mount form factor. This series is engineered for small die planar construction to support high di/dt performance in compact electronic designs.

Replacement Considerations

Compatible alternatives within the same family include S6002ESRP (TO-92) and S6002CSRP (Compak). These parts share identical electrical ratings but differ in physical package dimensions and mounting style. Verify footprint compatibility before substitution.
