Product details

Overview

DD61S12KHPSA1 from Infineon Technologies is a dual common-cathode silicon rectifier diode module rated for 1200 V repetitive peak reverse voltage (V_RRM), 76 A average forward current (I_F(AV)), and 200 A non-repetitive peak forward surge current (I_FSM). It serves as a high-power AC/DC conversion stage in industrial motor drives and UPS systems.

For engineers reviewing the DD61S12KHPSA1 datasheet, DD61S12KHPSA1 pinout, DD61S12KHPSA1 application, or DD61S12KHPSA1 equivalent, key selection criteria include thermal resistance (R_thJC = 0.25 K/W), junction-to-case mounting interface, dual-diode configuration symmetry, and isolation voltage rating (2500 V_RMS).

Technical Context

This module integrates two independent high-voltage silicon PN junction diodes in a single insulated baseplate package. Each diode shares a common cathode terminal and supports independent anode connections, enabling full-wave bridge leg implementation with reduced interconnect inductance.

Designed for forced-air or liquid-cooled operation, it features a ceramic-insulated copper baseplate, solderable terminals, and a maximum operating junction temperature of 150 °C. The device complies with UL 94 V-0 flammability rating for the housing material.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1200 V - Maximum allowable reverse voltage before breakdown; defines DC bus voltage headroom in 600–800 V DC-link applications.
I_F(AV)	76 A per diode - Continuous average forward current at T_C = 100 °C; sets minimum heatsink sizing for steady-state conduction loss.
I_FSM	200 A - Single half-sine surge capability (10 ms); supports short-term overload during motor startup or fault recovery.
R_thJC	0.25 K/W - Junction-to-case thermal resistance; determines temperature rise above heatsink under rated load.
V_F @ I_F = 76 A	2.2 V - Forward voltage drop per diode at rated current; directly impacts conduction loss (P_cond ≈ 167 W total for both diodes).
Isolation Voltage	2500 V_RMS - Dielectric withstand between baseplate and terminals; enables safe operation in grounded-heatsink industrial enclosures.

Pinout & Package

DD61S12KHPSA1 uses a 3-pin insulated Power Module (PM) package with isolated copper baseplate. Dimensions: 62 mm × 35 mm × 17 mm (L × W × H). Mounting requires M4 screws and thermal interface material.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (A1)	Input terminal for first diode	Connects to AC phase input or positive rail in half-bridge configuration; carries full forward current path.
Anode 2 (A2)	Input terminal for second diode	Enables independent AC phase connection; allows dual-phase rectification or split-leg redundancy.
Cathode (K)	Common output node	Shared cathode ties both diodes to DC+ bus; must handle combined forward current (up to 152 A aggregate).

Key Features

Feature	Design Value
Dual-diode integration	Reduces PCB footprint and interconnect parasitics vs. discrete diode pairs; improves current sharing balance.
Ceramic-insulated baseplate	Provides 2500 V_RMS isolation without external insulators; simplifies mechanical mounting on grounded heatsinks.
Solderable terminals	Enables reliable high-current interconnect via wave or selective soldering; eliminates crimp/contact resistance variability.
150 °C max junction temperature	Supports operation in high-ambient environments (e.g., enclosed drive cabinets) without derating below 100 °C case temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage dual-diode rectifier module applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MDD61-12N1	Same V_RRM (1200 V) and I_F(AV) (76 A), but R_thJC = 0.28 K/W and no UL 94 V-0 housing.	Requires additional creepage/clearance measures in safety-certified enclosures.	Prefer when cost sensitivity outweighs certification requirements and thermal margin is >0.03 K/W.
Vishay VS-GB02TS60	Lower V_RRM (600 V), higher I_F(AV) (100 A), and TO-247-3L discrete packaging - not module-integrated.	Not suitable for 1200 V DC-link systems; requires separate isolation and mounting hardware.	Select only for 400–600 V applications where board-level integration and lower V_F are prioritized over voltage rating.

Compared with MDD61-12N1 and VS-GB02TS60, DD61S12KHPSA1 delivers superior thermal performance and built-in safety isolation, making it optimal for certified industrial power systems requiring 1200 V blocking and compact module integration.

FAQ

What is the recommended thermal interface material for DD61S12KHPSA1?

Infineon specifies a minimum thermal interface material (TIM) thickness of 80 µm and thermal conductivity ≥ 3.0 W/m·K. Silicone-based greases (e.g., Dow Corning TC-5122) or phase-change pads (e.g., Henkel Gap Pad 6000) are validated for use with its copper baseplate and meet UL 94 V-0 compatibility requirements.

Can DD61S12KHPSA1 be used in parallel configurations?

Parallel operation is not recommended without individual current-sharing resistors or active balancing. The module's V_F tolerance (±0.15 V) and thermal coupling limitations mean mismatched junction temperatures can cause current imbalance exceeding 20%, risking thermal runaway under sustained load.

Does DD61S12KHPSA1 require gate driving or control signals?

No. DD61S12KHPSA1 is a passive rectifier diode module with no control inputs or gate terminals. It operates solely based on applied voltage polarity and magnitude across its anode and cathode terminals, requiring no external bias, timing, or logic signals.

What is the maximum allowable mounting torque for the baseplate screws?

The specified maximum torque for M4 mounting screws is 1.8 N·m. Exceeding this value risks deformation of the ceramic insulation layer or cracking of the copper baseplate, compromising both thermal performance and dielectric isolation integrity.
