C156D

Scrs Overview

The C156D is a Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It is classified as a standard recovery type device designed for high-power industrial applications. The component features a TO-83 package with stud mounting configuration, ensuring robust mechanical stability under thermal stress. Key electrical ratings include a repetitive peak off-state voltage of 1200V and an on-state current capacity of 100A RMS. The gate trigger characteristics are defined by a maximum gate trigger voltage of 3V and a maximum gate trigger current of 150mA. The device operates within a junction temperature range of -40°C to 125°C and supports non-repetitive surge currents up to 1400A at 50Hz.

Scrs Feature Summary

• Standard recovery characteristic suitable for general-purpose rectification and inversion circuits
• Stud mount construction in TO-83 package for efficient heat dissipation and secure installation
• High surge current capability providing resilience against transient load conditions

Scrs Applications

• Industrial motor drives and variable frequency drive inverters

• Static switch applications requiring high voltage blocking capability

Scrs Procurement Notes

Verify the specific manufacturer datasheet for the C156D to confirm exact pinout configurations and thermal resistance values before integration. Ensure that the mounting surface preparation meets the manufacturer's specifications for optimal thermal contact. Confirm RoHS compliance status directly with the supplier or original equipment manufacturer documentation, as regulatory requirements may vary by production batch and region.

Scrs Selection Notes

Select this component when designing circuits requiring a 1200V blocking voltage and 100A continuous current handling in a stud-mount form factor. Evaluate the thermal management requirements based on the specified junction temperature limits and ensure the gate drive circuit can supply the necessary trigger current without exceeding maximum ratings. Consider the physical dimensions of the TO-83 package for PCB or chassis layout constraints.
