Infineon Technologies DD104N16KKHPSA1

Overview

DD104N16KKHPSA1 from Semikron is a dual-arm press-pack rectifier diode module rated for 1600 V repetitive peak reverse voltage (VRRM), 104 A average on-state current (IFAVM) per arm 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 DD104N16KKHPSA1 datasheet, DD104N16KKHPSA1 pinout, DD104N16KKHPSA1 application, or DD104N16KKHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.185 °C/W per arm, DC), maximum surge current (2.9 kA, 10 ms), on-state voltage (1.4 V at 300 A, Tvj max), and pressure-contact Si pellet construction with AlN isolation.

Technical Context

This module integrates two independent high-current diode arms in a single press-pack housing, enabling full-wave rectification without external parallel devices. Each arm supports 1600 V blocking and handles up to 2.9 kA non-repetitive surge current under standardized 10 ms conditions.

Thermal performance is defined by dual-mode transient impedance models - one for natural cooling (KM14, 50W), another for forced-air cooling (KM14 + Papst 4650) - with analytical R–τ elements provided for precise junction temperature prediction across conduction angles (60°–180° sin/rec).

Key Specifications

Pinout & Package

DD104N16KKHPSA1 uses a dual-arm press-pack module package with two isolated anode-cathode pairs (Arm 1 and Arm 2), housed in a metal baseplate with AlN ceramic isolation. Electrical connections are made via M2 terminal screws (4 Nm torque) for main terminals and M1 mounting screws (4 Nm) for mechanical fixation. No PCB footprint or leaded pins - designed exclusively for bolt-down heatsink integration.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) is not independently specified - instead, the device is rated for IFAVM = 104 A at TC = 100°C. The absolute maximum junction temperature (Tvj max) is 150°C, and the operating case temperature range is -40°C to +150°C. Thermal design must ensure Tvj ≤ 150°C under worst-case load and ambient conditions.

Is DD104N16KKHPSA1 suitable for forced-air cooling only, or can it be used with natural convection?

Yes, it supports both cooling methods. Natural convection data is provided for KM14 (50W) heatsinks, while forced-air data references KM14 with Papst 4650 fans. The RthCH max is 0.10 °C/W per arm, so heatsink selection must match the chosen method to maintain Tvj ≤ 150°C at rated current.

Does this module include anti-parallel thyristors or is it diode-only?

DD104N16KKHPSA1 is a diode-only rectifier module with two independent, isolated diode arms. It contains no thyristors, SCRs, or gate-controlled devices. It is intended for uncontrolled rectification only; for phase-controlled operation, separate thyristor modules (e.g., SKKT series) are required.

What is the creepage distance and why does it matter for this module?

The creepage distance is 15 mm, measured across the insulated surface between high-voltage terminals and the baseplate. This value ensures safe operation at 1600 V blocking voltage under pollution degree 2 conditions, preventing surface tracking failure in humid or dusty industrial environments where long-term insulation integrity is critical.
