SJ6012N1RP

Scrs Overview

The Littelfuse SJ6012N1RP is a silicon-controlled rectifier (SCR) from the SJxx20xx series, designed for high-temperature applications. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 20 A. The device operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a maximum gate trigger current of 6 mA and a maximum holding current of 15 mA. It utilizes a D2PAK-2 surface-mount package.

Scrs Feature Summary

• High junction temperature capability up to 150°C
• Sensitive gate design requiring low trigger current
• Glass-passivated junctions for reliability

Scrs Applications

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

Scrs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact thermal and electrical ratings. Confirm RoHS compliance status through the manufacturer's environmental declaration. Ensure the D2PAK-2 footprint matches the target PCB layout before finalizing procurement orders.

Scrs Selection Notes

Select this component when a 20 A RMS current rating and 600 V blocking voltage are required in a surface-mount configuration. The sensitive gate characteristic simplifies drive circuitry compared to standard gate devices. Verify that the operating environment stays within the specified -40°C to +150°C junction temperature limits.

Scrs Part Context

This SCR belongs to the SJxx20xx series, which focuses on high junction temperature performance. It complements other Littelfuse thyristors by offering higher current capacity than the 12 A variants while maintaining a compact SMD form factor suitable for dense power electronics designs.

Scrs Replacement Considerations

The SV6012N1TP is a 12 A variant with similar packaging but lower current handling. Direct substitution requires verifying if the reduced 12 A RMS rating meets the application's load requirements.
