IRKL136/14

Overview

The IRKL136/14 is a high-power Silicon Controlled Rectifier module manufactured by Vishay General Semiconductor. It integrates one SCR and one series diode in an electrically isolated configuration. The device supports a maximum repetitive peak voltage of 1400V for both blocking and reverse states. It handles a maximum RMS on-state current of 135A. The unit utilizes a flange mount package design with five terminals, suitable for chassis mounting applications requiring robust power handling capabilities.

Feature Summary

• Integrates a single SCR and a built-in series diode within one compact module
• Provides electrical isolation between the main circuit and the heatsink via DBC ceramic technology
• Features glass-passivated chips to ensure high surge capability and reliability
• Utilizes a standard INT-A-PAK flange mount package for simple mechanical integration

Applications

• DC motor control systems
• Battery charging equipment
• Industrial welding machines
• Power converter circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm specific lot codes and manufacturing dates against current inventory records. Ensure proper handling procedures are followed due to the sensitive nature of semiconductor components. Check for any obsolescence notices or lifecycle changes from Vishay before finalizing procurement orders.

Selection Notes

Evaluate thermal management requirements based on the 135A RMS current rating and junction temperature limits. Ensure the application voltage does not exceed the 1400V repetitive peak specification. Consider the physical dimensions of the INT-A-PAK package for chassis mounting compatibility. Verify gate trigger characteristics match the driving circuit capabilities for reliable switching performance.

Part Context

This component belongs to the IRK series of thyristor modules designed for industrial power electronics. These modules combine high voltage blocking capabilities with significant current handling capacity. The series is widely used in heavy-duty applications where electrical isolation and high surge tolerance are critical for system stability and safety.

Replacement Considerations

Consult official Vishay documentation for cross-reference data. Potential substitutes may include other IRK series variants with matching voltage and current ratings. Verify pinout compatibility and thermal resistance specifications when considering alternative part numbers.
