Product details
Overview
DD82S08KHPSA1 from eupec (now Infineon Technologies) is a dual 800 V, 81 A average forward current, press-pack thyristor module designed for high-power phase-controlled rectification and AC line commutated inverters in industrial drives and HVDC converters. It features 1.55 V max forward voltage at 150°C/300 A, 0.47 °C/W thermal resistance per arm, and 2300 A non-repetitive surge current capability.
For engineers reviewing the DD82S08KHPSA1 datasheet, DD82S08KHPSA1 pinout, DD82S08KHPSA1 application, or DD82S08KHPSA1 equivalent, key selection criteria include repetitive peak reverse voltage (VRRM = 800 V), RMS forward current rating (IFRMSM = 150 A), transient thermal impedance ZthJC profile, reverse recovery charge Qr = 25 µAs at -diF/dt = 100 A/µs, and press-fit mounting torque specifications (M1/M2 = 4 Nm).
Technical Context
This device is a dual-arm, asymmetrical press-pack thyristor module with isolated gate terminals and common cathode configuration. Each arm supports 800 V blocking and handles up to 96 A average forward current at tc = 88°C, with junction-to-case thermal resistance of 0.47 °C/W per arm under DC conditions.
It operates in natural- or forced-commutated line-frequency applications requiring precise phase-angle control. The 25 µAs recovered charge (Qr) and 40 mA reverse leakage at 150°C/VRRM confirm its suitability for medium-speed switching in 50/60 Hz power conversion where dv/dt immunity and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - maximum repetitive reverse blocking voltage per arm; defines safe AC line voltage derating margin for 690 VAC systems |
| IFAVM @ tc=88°C | 96 A - continuous DC or average forward current per arm at heatsink temperature; sets base-load capacity in rectifier bridges |
| IFRMSM | 150 A - RMS forward current rating; determines thermal design basis for sinusoidal or trapezoidal load currents |

Pinout & Package
DD82S08KHPSA1 is housed in a press-pack ceramic-insulated module with two isolated anode terminals (A1, A2), one common cathode terminal (K), and two isolated gate terminals (G1, G2). Mounting uses M1 and M2 screws (4 Nm torque) for mechanical and thermal interface to heatsink.

| A2 | Anode of Arm 2 | High-side connection point for second thyristor arm; enables dual-arm phase-controlled operation |
| K | Common Cathode | Shared low-side return path; simplifies busbar layout in dual-arm bridge configurations |
| G1 | Gate of Arm 1 | Isolated trigger input for Arm 1; requires separate gate drive isolation and timing control |
| G2 | Gate of Arm 2 | Isolated trigger input for Arm 2; enables independent firing angle control per arm |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power thyristor module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon TT82N800 | Single-arm 800 V/82 A module; no common cathode; higher RthJC (0.52 °C/W) | Requires dual-module layout for same topology; less compact than DD82S08KHPSA1's integrated dual-arm form factor | Select when modular redundancy or separate thermal management per arm is preferred |
| Mitsubishi CM800HA-28H | 800 V/800 A IFRMSM rating; 0.12 °C/W RthJC; uses solderable baseplate instead of press-pack | Designed for liquid-cooled systems; incompatible with press-fit heatsink interfaces and high-voltage isolation requirements | Select only for high-RMS, liquid-cooled applications where 2.5 kV insulation is not required |
Compared with TT82N800 and CM800HA-28H, DD82S08KHPSA1 uniquely combines dual-arm integration, press-pack isolation, and 2.5 kV insulation-making it irreplaceable in air-cooled, space-constrained, high-safety-class medium-voltage converter valves.

FAQ
What is the maximum allowable junction temperature for DD82S08KHPSA1?
The maximum junction temperature (tvj max) is 150°C, as specified in the thermal characteristics section. This limit applies under both steady-state and transient conditions, and must be enforced via heatsink design and thermal monitoring to prevent irreversible degradation of the thyristor die and internal interconnects.
Does DD82S08KHPSA1 require forced gate triggering or can it operate with simple pulse transformers?
DD82S08KHPSA1 requires isolated, high-dI/dt gate triggers capable of delivering ≥2 A peak current for reliable turn-on. Pulse transformers meeting IEC 61800-5-1 isolation and dv/dt immunity are acceptable, but gate drive circuits must provide sufficient di/dt (>2 A/µs) and maintain >500 V isolation between gate and main terminals.
Can DD82S08KHPSA1 be used in anti-parallel configuration for bidirectional AC switching?
No-DD82S08KHPSA1 is a unidirectional thyristor module with common cathode architecture. For bidirectional AC switching, two modules must be connected in inverse-parallel, or a dedicated anti-parallel thyristor/diode module (e.g., eupec DD92N1200) should be selected instead.
What is the creepage distance and why does it matter for this part?
The creepage distance is 14 mm, measured across the ceramic insulator between high-voltage terminals and the heatsink mounting surface. This value ensures compliance with IEC 60664-1 pollution degree 2 requirements for indoor industrial environments, preventing surface tracking failure under humid or dusty conditions.
