Infineon Technologies DD89N12KHPSA1

Overview

DD89N12KHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 1200 V repetitive peak reverse voltage, 89 A average on-state current per arm at TC = 100°C, and 140 A RMS on-state current. It features silicon die with AlN internal insulation, 0.225 °C/W junction-to-case thermal resistance per module (180° sine conduction), and is designed for industrial AC/DC conversion in high-reliability power supplies and motor drive front-ends.

For engineers reviewing the DD89N12KHPSA1 datasheet, DD89N12KHPSA1 pinout, DD89N12KHPSA1 application, or DD89N12KHPSA1 equivalent, key selection criteria include its 1200 V VRRM rating, 2.8 kA non-repetitive surge current capability, 1.5 V max forward voltage at 300 A and Tvj max, pressure-contact construction, and dual-arm configuration supporting B2/B6 bridge topologies.

Technical Context

This dual-diode module implements a two-arm, common-cathode configuration optimized for single-phase (B2) and three-phase (B6) bridge rectification. Each arm supports independent thermal and electrical operation with isolated Si pellets mounted on AlN ceramic substrates.

It operates across -40°C to +150°C case temperature range, with maximum junction temperature of 150°C and transient thermal impedance ZthJC characterized by analytical R–τ network elements for precise loss modeling under pulsed loads.

Key Specifications

Pinout & Package

DD89N12KHPSA1 is housed in a press-pack module with two isolated diode arms sharing a common cathode terminal. The mechanical package uses M1 mounting screws (4 Nm torque, ±15% tolerance) and M2 terminal screws (4 Nm, ±10% tolerance) for high-reliability clamping to heatsinks. Weight is 160 g; creepage distance is 15 mm.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature is +150°C, aligned with the device's maximum junction temperature of 150°C and specified thermal resistance values. Operation at TC = 100°C enables full-rated 89 A average current per arm; derating applies above this point per the TC vs. IFAVM curve in the datasheet.

Does DD89N12KHPSA1 require thermal interface material between module and heatsink?

Yes-thermal paste or phase-change material is required between the module baseplate and heatsink to minimize contact resistance. The specified RthCH (0.05 °C/W max per module) assumes proper surface finish, flatness, and mounting torque (4 Nm ±15%) applied to M1 screws.

Can this module be used in a single-phase full-wave center-tap configuration?

No-DD89N12KHPSA1 has a common-cathode dual-anode structure, making it suitable only for B2 (single-phase bridge) or B6 (three-phase bridge) topologies. A center-tap rectifier requires separate, isolated diodes or a common-anode configuration not supported here.

What is the significance of the "HPSA1" suffix in the part number?

The "HPSA1" suffix denotes Semikron's standard press-pack housing variant with AlN insulation, M1/M2 screw terminals, and compliance with K.Spec A10/91 mechanical and thermal specifications. It distinguishes this version from earlier revisions or alternative packaging options like bolt-down or spring-clip variants.
