DD435N34KHPSA1

Diode Arrays Overview

The DD435N34KHPSA1 is a silicon single rectifier diode module from Infineon's Power Block series, utilizing pressure contact technology. It features a 3400 V repetitive peak reverse voltage and a 435 A average forward current rating at 180° electrical sine wave operation. The device has a maximum forward voltage of 1.71 V and operates within a junction temperature range of -40°C to +150°C. Designed for high reliability, it includes an electrically insulated baseplate and supports fuseless design due to high overload capability.

Diode Arrays Feature Summary

• Pressure contact technology ensures high reliability and robust industrial standard packaging.
• Electrically insulated baseplate provides short-circuit fail safety and prevents arcing on failure.
• High overload capability allows for fuseless circuit design in demanding applications.

Diode Arrays Applications

• Phase control systems
• Traction drives
• Industrial motor control

Diode Arrays Procurement Notes

Verify the exact ordering suffix against official Infineon documentation to confirm pinout and mechanical specifications. Confirm RoHS compliance status and specific thermal resistance values required for your heatsink design. Ensure the screw mounting torque meets manufacturer guidelines to maintain optimal thermal performance and electrical contact integrity during operation.

Diode Arrays Selection Notes

Select this component for high-power DC or AC rectification where high surge current handling is critical. The 34 mm housing size fits standard industrial mounting profiles. Consider the thermal resistance characteristics when designing the cooling system. Verify that the 435 A continuous current rating aligns with the load requirements under the expected ambient temperature conditions.

Diode Arrays Part Context

This part belongs to the DD435N family of high-power diode modules. It shares the same core die and package structure as variants like DD435N36K and DD435N40K, differing primarily in voltage rating. The HPSA1 suffix denotes specific manufacturing and testing parameters defined by Infineon for quality assurance and traceability.

Diode Arrays Replacement Considerations

Direct substitutes include other DD435N series variants such as DD435N36K or DD435N40K if voltage ratings permit. Cross-referencing with DZ435N models may be possible but requires verification of the single vs. bridge configuration and mounting interface compatibility.
