C152N

Scrs Overview

The Powerex C152N is a high-power Silicon Controlled Rectifier (SCR) designed for phase control applications. It features an average on-state current rating of 1460 to 1640 Amperes and supports repetitive peak reverse voltages ranging from 500 to 1400 Volts depending on the specific suffix variant. The device utilizes a stud configuration with four terminals, including gate and cathode connections. Key electrical characteristics include a maximum DC gate trigger current of 200 mA and a maximum DC gate trigger voltage of 5 V. The module exhibits a critical rate of rise of off-state voltage of 400 V/µs and a non-repetitive peak on-state current capacity of up to 29,000 A. It operates within a junction temperature range extending to 125 °C.

Scrs Procurement Notes

Verify the exact voltage and current suffix against the datasheet before ordering, as the base number covers multiple variants. Confirm package compatibility and thermal interface requirements. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability.

Scrs Selection Notes

Select the appropriate voltage rating suffix based on the circuit's peak reverse voltage requirements. Evaluate the thermal management solution to maintain junction temperatures within the specified 125 °C limit under continuous load conditions. Consider the gate drive specifications to ensure reliable triggering within the defined current and voltage limits.

Scrs Part Context

This component belongs to Powerex's lineup of high-power discrete SCRs and modules. It is engineered for heavy-duty phase control tasks where high current density and ruggedness are required.
