TDK4453002DH

Scrs Overview

The Powerex TDK4453002DH is a high-voltage, high-current disc pack phase control thyristor (SCR) rated for 4400V repetitive peak voltage and 3070A average on-state current. It features a high di/dt gate structure enabling reliable operation under demanding conditions. The device utilizes a hermetic ceramic package and offers excellent surge and I²t ratings. Key electrical characteristics include a maximum turn-off time of 600µs at 125°C, a critical rate-of-rise of on-state current of 150 A/µs non-repetitive, and a peak one-cycle surge current of 52,797A at 50Hz.

Scrs Feature Summary

• High di/dt and dv/dt capability enabled by specialized gate design
• Hermetic ceramic package construction
• Excellent surge and I²t ratings

Scrs Applications

• DC power supplies
• Motor controls

Scrs Procurement Notes

Verify the specific part number against official Powerex documentation to confirm voltage and current codes match project requirements. Ensure mounting force specifications between 18,000 and 25,000 lbs are accommodated in the mechanical design. Confirm thermal management strategies align with the provided junction-to-case thermal resistance data for double-side cooling applications.

Scrs Selection Notes

Select this component for applications requiring robust phase control thyristors with high surge handling capabilities. Consider the 4400V rating and 3070A current capacity when designing systems operating at elevated temperatures or requiring high reliability. Evaluate the need for double-side cooling given the low thermal resistance values specified for junction-to-case and case-to-sink interfaces.
