T600161504BT

Overview

The T600161504BT is a silicon-controlled rectifier (SCR) manufactured by Powerex Inc., designed for high-power phase control applications. It features a 1.6 kV off-state voltage rating and supports an RMS on-state current of 235 A, with an average on-state current capacity of 175 A. The device utilizes a standard recovery type structure and operates within a junction temperature range of -40°C to 125°C. Key electrical parameters include a maximum gate trigger voltage of 3 V and a maximum gate trigger current of 150 mA. The forward voltage drop at maximum current is specified at 1.8 V. It is housed in a TO-209AB package with stud mounting capabilities.

Feature Summary

• High-voltage blocking capability rated at 1.6 kV for robust off-state performance
• Standard recovery characteristics optimized for phase control switching applications
• Stud mount chassis configuration ensuring secure mechanical installation and thermal management

Applications

• Industrial motor drives and variable frequency drive systems
• High-power DC-to-AC inversion circuits
• Resistive and inductive load phase control regulators

Procurement Notes

Verify the specific datasheet revision and manufacturer part number against official Powerex documentation before procurement. Confirm that the required thermal interface materials and mounting hardware are compatible with the TO-209AB stud mount specification. Ensure that the application circuit design accounts for the standard recovery time and gate trigger requirements to guarantee reliable switching operation under expected load conditions.

Selection Notes

Select this component when high voltage isolation and substantial current handling are required for phase control tasks. The 1.6 kV rating provides sufficient margin for industrial line voltages, while the 235 A RMS capacity suits heavy-duty loads. Consider the standard recovery profile for general-purpose switching rather than high-frequency applications. Evaluate the thermal resistance and heatsinking requirements based on the 1.8 V forward voltage drop at full load to maintain junction temperatures within the specified operational limits.

Part Context

This SCR belongs to the T600 series from Powerex Inc., which focuses on high-power thyristor solutions for demanding industrial environments. The series is characterized by rugged construction and reliable performance in phase control and rectification roles. The T600161504BT specifically addresses applications requiring higher voltage ratings compared to lower-voltage counterparts in the same product family, maintaining consistent mounting and electrical interface standards.

Replacement Considerations

Cross-reference with other Powerex T600 series SCRs offering similar 1.6 kV ratings and comparable current capacities. Verify pinout compatibility and thermal characteristics when substituting with equivalent devices from other manufacturers to ensure seamless integration into existing chassis designs without modifying mounting structures.
