SV6012R2TP

Overview

The Littelfuse SV6012R2TP is a silicon-controlled rectifier (SCR) belonging to the SVxx12xx series, designed for high junction temperature applications. It features a TO-220L through-hole package with three pins. Key electrical parameters include a repetitive peak reverse voltage of 600 V and an average on-state current of 12 A. The device supports a non-repetitive surge current of 120 A. Gate triggering characteristics are defined by a maximum gate trigger current of 6 mA and a maximum gate trigger voltage of 1.5 V. The component operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• High junction temperature capability suitable for demanding thermal environments
• Low gate trigger current enabling efficient control circuitry
• Robust surge current handling for inrush and transient protection

Applications

• Phase control in heating systems
• Motor speed controls
• Converters and rectifiers
• Inrush current control
• Capacitive discharge ignitions

Procurement Notes

Verify the specific suffix 'R2' against official Littelfuse documentation to confirm pinout orientation or marking variations compared to standard variants. Ensure the procurement channel provides original manufacturer data sheets. Confirm RoHS compliance status for the specific batch. Validate that the TO-220L package matches the design footprint requirements before ordering.

Selection Notes

Select this component when a 600 V blocking voltage and 12 A continuous current rating are required in a through-hole configuration. The low 6 mA gate trigger current allows for direct interfacing with many logic-level drivers without additional amplification. Consider the 150°C maximum junction temperature for applications with limited cooling or high ambient temperatures where standard SCRs might fail.

Part Context

This SCR is part of the SVxx12xx series from Littelfuse, which focuses on high junction temperature performance. The series is engineered for uni-directional switching tasks. The TO-220L package provides mechanical stability and thermal dissipation capabilities suitable for power electronics. This model represents a specific voltage and current variant within the broader family of phase control devices.

Replacement Considerations

Direct replacements must match the 600 V rating, 12 A current capacity, and TO-220L package. Verify gate trigger specifications to ensure compatibility with existing drive circuits. Check if alternative manufacturers offer equivalent high-temperature variants with identical pinouts.
