Infineon Technologies DD260N12KAHPSA1

Overview

DD260N12KAHPSA1 from Infineon Technologies is a press-pack rectifier diode module rated for 1200 V repetitive peak reverse voltage (VRRM), 260 A average forward current (IFAVM) at TC = 100 °C, and 9500 A non-repetitive surge current (IFSM). It features electrically insulated baseplate, pressure-contact silicon die construction, and 0.164 K/W junction-to-case thermal resistance per arm - deployed in industrial drive rectification, UPS input stages, battery charger front-ends, and crowbar protection circuits.

For engineers reviewing the DD260N12KAHPSA1 datasheet, DD260N12KAHPSA1 pinout, DD260N12KAHPSA1 application, or DD260N12KAHPSA1 equivalent, key selection criteria include verified VRRM/VDRM range (1200–1800 V), IFAVM derating vs. case temperature, RthJC max per arm (0.164 K/W), VT0 (0.70 V), rT (0.68 mΩ), and isolation test voltage (3.6 kV RMS/1 sec).

Technical Context

This double-diode press-pack module uses pressure-contact technology with AlN-based internal insulation (Class I, IEC 61140) and is configured as a dual-arm, single-phase bridge-compatible rectifier. Each arm supports 260 A average forward current at 100 °C case temperature and withstands 1200–1800 V blocking voltage depending on variant suffix.

Thermal performance is defined by transient ZthJC curves and DC RthJC values (0.082–0.164 K/W per arm), with mechanical mounting torque specified at 6 Nm (M1) and 12 Nm (M2). The module operates across -40 °C to +150 °C junction and case temperature ranges.

FAQ

What is the maximum allowable junction temperature for DD260N12KAHPSA1?

The maximum junction temperature (Tvj max) is 150 °C, validated per IEC 60747-2 and confirmed in the 2018 datasheet revision 3.2. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must ensure that calculated junction temperature - derived from Ploss × RthJC + TC - remains ≤150 °C under worst-case load and ambient conditions.

Does DD260N12KAHPSA1 require external gate drive or control signals?

No - DD260N12KAHPSA1 is an uncontrolled power diode module with no gate or control terminals. It conducts when forward-biased and blocks when reverse-biased, relying solely on external circuit voltage polarity and magnitude. Its two independent diode arms operate autonomously without timing, triggering, or bias circuitry.

Can DD260N12KAHPSA1 be paralleled with identical units for higher current capacity?

Yes, but only with strict current-sharing design: matched thermal mounting (identical RthCH), symmetrical busbar layout, and dynamic impedance balancing via external ballast inductors or resistors. The datasheet does not guarantee inherent current sharing due to parameter spread in VT0 (±5%) and rT (±10%), so forced current sharing must be implemented at system level.

What is the creepage distance specification and its safety implication?

The creepage distance is 17 mm, measured across the insulated baseplate surface between terminals and heatsink interface. This meets IEC 61800-5-1 requirements for Pollution Degree 3 environments and supports reinforced insulation at 1200 V DC working voltage, enabling safe use in grounded-heatsink industrial enclosures without additional potting or barriers.
