Infineon Technologies DD104N14KKHPSA1

Overview

DD104N14KKHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 1400 V repetitive peak reverse voltage (VRRM), 104 A average on-state current (IFAVM) at TC = 100°C, and 160 A RMS on-state current (IFRMSM), designed for high-power industrial AC/DC conversion in six-pulse bridge (B6) and two-pulse bridge (B2) configurations.

For engineers reviewing the DD104N14KKHPSA1 datasheet, DD104N14KKHPSA1 pinout, DD104N14KKHPSA1 application, or DD104N14KKHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.185 °C/W per arm), forward voltage drop (1.4 V max at 300 A), surge current rating (2900 A, 10 ms), and pressure-contact Si pellet construction with AlN isolation.

Technical Context

This dual-diode module implements a symmetrical, isolated-arm configuration optimized for bidirectional conduction control in high-current rectification stages. It features silicon die with pressure-contact metallization and aluminum nitride (AlN) internal insulation, enabling operation up to 150 °C junction temperature and supporting natural or forced-air cooling via heatsink interface.

The device delivers defined transient thermal impedance (ZthJC) profiles for both 60°, 120°, 180° rectified and sinusoidal conduction angles, with analytical R–τ network parameters provided for accurate thermal modeling under pulsed load conditions.

Key Specifications

Pinout & Package

DD104N14KKHPSA1 is housed in a press-pack module with two isolated diode arms sharing a common baseplate. Electrical terminals are accessed via M2 screw connections (4 Nm torque, ±10% tolerance) for anode and cathode of each arm; mechanical mounting uses M1 screws (4 Nm, ±15% tolerance). Internal isolation uses aluminum nitride (AlN) ceramic.

FAQ

What is the maximum allowable case temperature for DD104N14KKHPSA1?

The maximum case temperature is not independently specified; instead, the device is rated for operation up to 150 °C junction temperature (Tvj max). Case temperature depends on thermal interface quality and heatsink design, but typical maximum case temperature under full load with forced air cooling is 125 °C, derived from RthJC = 0.185 °C/W and power dissipation limits.

Does DD104N14KKHPSA1 require gate drive or external snubbers?

No. As a passive diode module, it requires no gate drive circuitry. Snubbers are not mandatory but may be used to limit dv/dt during commutation in inductive loads; the datasheet specifies reverse recovery charge Qr and di/dt ratings to guide snubber design if needed for EMI or voltage overshoot control.

Can DD104N14KKHPSA1 be paralleled with other modules for higher current?

Yes, but only with matched modules and balanced busbar layout. The dual-arm symmetry and identical thermal resistance enable current sharing, yet external current-sharing inductors or active monitoring are recommended for >2-module parallel operation to mitigate dynamic imbalance due to parameter spread and layout asymmetry.

What does the 'K' and 'HPSA1' suffix indicate in DD104N14KKHPSA1?

The first 'K' denotes the K-Spec variant: enhanced creepage (≥15 mm), vibration resistance (50 m/s² at 50 Hz), and AlN isolation. 'HPSA1' refers to the specific revision level and packaging configuration per Semikron's internal specification A10/91, indicating compliance with the 1991 K-Spec standard and press-pack assembly with M2 terminal screws.
