SJ6006VS2TP

Overview

The Littelfuse SJ6006VS2TP is a high-temperature sensitive Silicon-Controlled Rectifier (SCR) from the SJxx06xSx series, designed for uni-directional switching applications. It features a 6 A RMS on-state current rating and supports blocking voltages of 400 V or 600 V. The device utilizes a TO-251AA (TO-251-3) through-hole package with a maximum junction temperature of 150°C. Key electrical characteristics include a peak non-repetitive surge current of 100 A at 60 Hz, a gate trigger current (IGT) maximum of 200 µA, and a gate trigger voltage (VGT) maximum of 0.8 V. It exhibits a holding current (IH) maximum of 6 mA and a typical turn-on time of 6 µs.

Feature Summary

• Sensitive gate architecture enabling direct interfacing with microprocessors via low gate trigger current requirements.
• High thermal capability supporting operation up to a 150°C junction temperature for demanding environments.
• Robust surge handling with 100 A peak non-repetitive on-state current capability at 60 Hz.

Applications

• Capacitive discharge ignition systems for motorcycle engines and portable generators.
• Strobe lights and pneumatic nailers.
• Power tool controls and home appliance motor speed regulation.

Procurement Notes

Verify the specific voltage rating suffix (400 V or 600 V) required for the circuit design, as the base part number covers both options. Confirm that the TO-251AA through-hole package aligns with the PCB footprint constraints. Ensure the sensitive gate specifications meet the drive circuit capabilities before finalizing the order.

Selection Notes

Select this component when low gate drive power is necessary or when interfacing directly with logic-level controllers. The 6 A RMS rating suits moderate power phase control tasks. Consider the 150°C junction limit for high-ambient temperature designs. Verify that the 100 A surge rating exceeds the expected inrush currents in the application.

Part Context

This device belongs to the SJxx06xSx & SJxx06xx family of 6 Amp High Temperature SCRs manufactured by Littelfuse. The 'S2' designation specifically identifies the sensitive gate variant within the series, distinguishing it from standard gate versions which require higher trigger currents. The 'TP' suffix indicates tube packaging.

Replacement Considerations

Cross-reference with other Littelfuse SJxx06xS2 devices for different voltage ratings or package types (e.g., SJ6006DS2TP for TO-252). Verify that any substitute maintains the 200 µA maximum gate trigger current and 150°C junction temperature rating to ensure functional equivalence.
