Product details
Overview
VS-SD1100C32J from Vishay Semiconductors is a high-current, stud-mount silicon rectifier diode in a Hockey-PUK package (DO-200AB), rated for 1100 A average forward current, 3200 V peak repetitive reverse voltage, and 150 °C maximum junction temperature. It serves as a main power conversion element in industrial DC drives, medium-voltage UPS inverters, and traction rectification systems.
For engineers reviewing the VS-SD1100C32J datasheet, VS-SD1100C32J pinout, VS-SD1100C32J application, or VS-SD1100C32J equivalent, key selection considerations include thermal interface requirements, clamping force specification (12–14 kN), double-sided cooling compatibility, and DO-200AB mechanical mounting constraints.
Technical Context
This device is a single-die, planar-passivated, stud-mounted power rectifier with axial current flow through a copper-molybdenum-copper baseplate structure. Its low thermal resistance (0.012 °C/W junction-to-case) relies on externally applied mechanical clamping pressure and double-sided heatsink contact.
The VS-SD1100C32J operates under forced-air or liquid-cooled conditions with specified mounting pressure of 12–14 kN and requires thermal compound (e.g., Penetrox A) at both interfaces. It is not gate-controlled and exhibits no reverse recovery charge specification - confirming its use as a line-frequency, hard-commutated rectifier.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 1100 A - continuous DC output current capability under double-sided cooling at 100 °C heatsink temperature |
| VRRM | 3200 V - maximum allowable repetitive reverse voltage without breakdown during AC line commutation |
| VFM @ IFM | 2.7 V @ 2200 A - forward voltage drop defining conduction loss and thermal load at peak surge current |
| Rth(j-c) | 0.012 °C/W - junction-to-case thermal resistance achievable only with specified clamp force and thermal interface |
| Tj(max) | 150 °C - absolute maximum silicon junction temperature limiting safe operating area under transient overload |
| Mounting Type | Stud-mount Hockey-PUK (DO-200AB) - requires external clamping system, no solderable leads or PCB footprint |
Pinout & Package
VS-SD1100C32J uses a two-terminal, stud-mount Hockey-PUK (DO-200AB) metal-ceramic package with axial current path: anode stud and cathode stud. No PCB pinout applies; terminals are threaded M12 studs for mechanical clamping between heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode Stud | Positive DC output terminal / high-side current entry | M12 threaded copper alloy stud accepting clamp force; must be electrically isolated from heatsink via ceramic insulator |
| Cathode Stud | Negative DC output terminal / low-side current exit | M12 threaded copper alloy stud; forms second current path and thermal interface to opposite heatsink |
Key Features
| Feature | Design Value |
|---|---|
| DO-200AB Package | Standardized international stud-mount form factor enabling mechanical interchangeability across OEM heatsink designs |
| 12–14 kN Clamping Force | Precisely defined mechanical requirement ensuring repeatable thermal resistance and electrical contact integrity |
| Double-Sided Cooling Support | Enables 2× thermal dissipation vs. single-sided mounting - critical for >1 MW rectifier stacks |
| 150 °C Junction Rating | Allows operation in high-ambient industrial environments (e.g., steel mill substations, marine propulsion rooms) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MDD1100-32 | Same 1100 A / 3200 V rating; TO-200AB package; slightly higher VFM (2.85 V @ 2200 A) | Compatible in double-sided cooled stacks but requires different clamp geometry due to TO-200AB flange dimensions | Select when existing heatsink tooling matches IXYS flange pattern and higher VFM is acceptable |
| Infineon SKKH 1100/32 | Identical DO-200AB footprint; lower Rth(j-c) (0.010 °C/W); tighter VRRM tolerance (±2.5 %) | Preferred for mission-critical redundancy systems requiring tighter voltage margin control | Select when thermal budget is constrained and ±2.5 % VRRM tolerance is required for paralleling reliability |
Compared with VS-SD1100C32J, MDD1100-32 offers identical ratings but different mechanical interface, while SKKH 1100/32 delivers superior thermal performance and tighter voltage tolerance - both require verification of clamp force calibration and thermal paste compatibility before integration.

FAQ
What is the correct clamping force for VS-SD1100C32J?
The VS-SD1100C32J requires a precisely controlled clamping force of 12–14 kN to achieve its specified thermal resistance and electrical contact integrity. This force must be applied using a calibrated spring-type clamp with Bellville washers or flex spring bar, as outlined in Vishay Application Note 95544. Exceeding or falling below this range risks thermal runaway or contact failure. Always verify force with a torque-calibrated tool per heatsink assembly step.
Can VS-SD1100C32J be used with single-sided cooling?
Yes, VS-SD1100C32J supports single-sided cooling (SSC), but its rated 1100 A IF(AV) assumes double-sided cooling (DSC) at 100 °C heatsink temperature. Under SSC, derating is mandatory - typically to ≤550 A at same heatsink temperature. Thermal resistance increases significantly, requiring larger heatsinks or active cooling enhancements to maintain Tj ≤ 150 °C.
What thermal compound is recommended for VS-SD1100C32J?
Vishay specifies Penetrox A or Penetrox A13 thermal compound for VS-SD1100C32J, applied as a uniform 100 μm layer on both contact surfaces. These compounds provide stable thermal conductivity (>6 W/m·K) and oxidation resistance under high-pressure clamping. Substitutes must meet minimum dielectric strength (>10 kV/mm) and thermal stability up to 180 °C to avoid degradation during extended operation.
Is VS-SD1100C32J suitable for high-frequency switching applications?
No, VS-SD1100C32J is not designed for high-frequency switching. It is a line-frequency rectifier with no specified reverse recovery time or Qrr - confirming its intended use in 50/60 Hz or 120–360 Hz phase-controlled rectifiers. Using it in PWM or高频 inverters would cause excessive switching losses and premature failure due to slow carrier recombination dynamics.
What is the maximum allowable junction temperature for VS-SD1100C32J?
The maximum allowable junction temperature for VS-SD1100C32J is 150 °C, as defined in its absolute maximum ratings. Operation beyond this limit risks irreversible degradation of the silicon die and passivation layers. Real-time thermal monitoring must ensure Tj remains within this bound under worst-case load, ambient, and cooling conditions - especially during short-time overloads or cooling system faults.
