Overview
The Powerex T7H8167504DN is a Phase Control Silicon Controlled Rectifier (SCR) module rated for 750 Amperes average current and 1600 Volts repetitive peak reverse voltage. It features a hermetic Press-Pak Pow-R-Disc construction with an amplifying gate design. The device supports RMS on-state currents up to 1260 A at 55°C case temperature and handles non-repetitive surge currents of 10,500 A at 60 Hz. Key electrical parameters include a typical turn-off time of 150 µs, a maximum gate trigger current of 150 mA, and a peak on-state voltage of 1.40 V.
Feature Summary
- Hermetic packaging utilizing all-diffused Pow-R-Disc technology
- Amplifying gate structure for reliable triggering
- High di/dt and dv/dt capabilities
- Robust surge and I²t ratings
Applications
- Power Supplies
- Motor Control
Procurement Notes
Verify the complete 12-digit part number against official Powerex documentation to ensure correct voltage and current specifications. Confirm thermal management requirements align with the specified junction-to-case resistance values. Ensure mounting force specifications are met during installation to maintain proper thermal contact and device integrity.
Selection Notes
Select this component for high-power phase control applications requiring robust surge handling and fast switching characteristics. Evaluate thermal dissipation needs based on the specific duty cycle and waveform, as performance varies significantly between sinusoidal and rectangular waveforms. Consider the operating temperature range and required cooling methods to stay within the absolute maximum ratings.
Part Context
This device belongs to the T7H8 series of Phase Control SCRs manufactured by Powerex Inc. The series offers various voltage ratings from 200V to 1600V while maintaining a consistent 750A average current rating. These modules are designed for industrial power conversion systems where reliability under high stress conditions is critical.
Replacement Considerations
Consult official Powerex documentation for direct substitutes within the T7H8 family or equivalent models from other manufacturers that match the 750A/1600V specification and Press-Pak form factor.
