SV6012R1TP

Overview

The Littelfuse SV6012R1TP 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. Triggering characteristics specify a maximum gate trigger current of 6 mA and a maximum gate trigger voltage of 1.5 V. The holding current is rated at a maximum of 35 mA. 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 requirement facilitating simple drive circuitry
• Robust surge current handling for inrush control and capacitive discharge ignition

Applications

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

Procurement Notes

Verify the specific suffix 'R1' against official Littelfuse documentation to confirm pinout orientation and marking details, as variations exist within the SV series. Ensure the selected variant matches the required TO-220L lead configuration for the target PCB layout. Cross-reference RoHS compliance status with the latest manufacturer release notes prior to final procurement.

Selection Notes

Select this component when a 600 V blocking voltage and 12 A continuous current rating are required in a through-hole package. The low gate trigger current makes it suitable for microcontroller-driven applications without additional amplification. Verify that the thermal management design can sustain the 150°C maximum junction temperature during operation.

Part Context

This SCR is part of the SVxx12xx family from Littelfuse, which specializes in high junction temperature thyristors. The series is engineered for uni-directional switching applications requiring reliable performance under high thermal stress. It complements other power semiconductors in industrial power control and motor drive systems.

Replacement Considerations

Direct substitutes may include other 600 V, 12 A SCRs in TO-220L packages from manufacturers such as Vishay or Microsemi. Verify equivalent gate trigger currents and holding currents to ensure circuit compatibility. Surface-mount equivalents like the SV6012N1TP require different PCB footprints.
