2N1794

Overview

The 2N1794 is a standard recovery silicon controlled rectifier (SCR) manufactured by Powerex Inc. It features a center-fired, dynamic gate structure and an all-diffused design. The device is rated for a repetitive peak off-state voltage of 150 V and has an on-state RMS current rating of 110 A. It utilizes compression bonded encapsulation to ensure robust thermal performance and mechanical stability under high-power conditions.

Feature Summary

Center-fired, dynamic gate architecture for reliable triggering
All-diffused design construction
Low gate current requirements
Compression bonded encapsulation for enhanced durability

Applications

Industrial automation systems
Process automation control circuits
High-power module implementations

Procurement Notes

Verify the manufacturer source carefully as multiple entities including Microsemi and Semitronics have historically referenced this part number. Confirm that the specific unit received matches the Powerex Inc. specifications regarding the 150V rating and 110A current capacity. Ensure the component is a genuine Powerex product rather than a generic equivalent when sourcing through third-party distributors.

Selection Notes

Select the 2N1794 for applications requiring a rugged, chassis-mount SCR with a 150V blocking capability. Its low gate current characteristic simplifies drive circuit design compared to higher-gate-requirement alternatives. The compression bonded package is suitable for heavy-duty industrial environments where thermal cycling and mechanical stress are significant factors in component longevity.

Part Context

This thyristor belongs to the family of standard recovery SCRs designed for general-purpose high-current switching. It is commonly found in power conversion and motor control assemblies. The TO-94 style stud mount facilitates direct heat sinking to chassis structures, providing efficient thermal management for continuous operation in demanding electrical loads.
