Product details
Overview
VS-SD1100C16L from Vishay Semiconductors is a standard recovery power diode in hockey PUK (B-43) package, rated for 1600 V repetitive peak reverse voltage (VRRM), 1400 A average forward current (IF(AV)) with double-side cooling, and 13,000 A non-repetitive surge current (IFSM @ 10 ms, 50 Hz). It features a diffused junction, low forward voltage drop (1.31 V at 1500 A, TJ = 180 °C), and thermal resistance of 0.038 K/W (junction-to-heatsink, double-side cooled). It is used in high-power industrial rectification circuits such as medium-voltage DC drives and traction converters.
For engineers reviewing the VS-SD1100C16L datasheet, VS-SD1100C16L pinout, VS-SD1100C16L application, or VS-SD1100C16L equivalent, key selection criteria include VRRM = 1600 V, IF(AV) = 1400 A (double-side cooled), IFSM = 13,000 A, RthJ-hs = 0.038 K/W, and B-43 mechanical interface compatibility with heatsink mounting force of 9800 N.
Technical Context
This diode operates as a single-element, unidirectional, standard-recovery rectifier with diffused PN junction optimized for high-current, medium-frequency line-commutated applications. Its conduction behavior follows half-sine wave averaging with defined thermal derating across conduction angles (30°–180°) and cooling configurations.
It delivers stable forward conduction with VF(TO)1 = 0.78 V and rf1 = 0.35 mΩ (low-current region), and VF(TO)2 = 0.94 V with rf2 = 0.26 mΩ (high-current region), enabling accurate loss modeling in high-power converter designs. Junction temperature range is –40 °C to +180 °C for the 400–2000 V voltage code group, matching VS-SD1100C16L's 1600 V rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1600 V maximum repetitive peak reverse voltage - defines maximum DC blocking capability in rectifier bridge arms |
| IF(AV) | 1400 A average forward current at 55 °C heatsink temperature, double-side cooled - sets continuous DC output current capacity |
| IFSM | 13,000 A peak non-repetitive surge current (10 ms, 50 Hz, no voltage reapplied) - determines short-circuit withstand in motor drive fault conditions |

| Case Style | B-43 hockey PUK package - standardized ceramic-insulated, stud-mount mechanical interface with 42 mm anode/cathode diameter |
Pinout & Package
B-43 hockey PUK package: dual stud-mount configuration with isolated anode (A) and cathode (C) terminals, 42 mm maximum diameter, 9800 N ±10 % mounting force requirement, and 83 g mass. Designed for direct bolt-down to liquid- or forced-air-cooled heatsinks with thermal interface material.

FAQ
What is the maximum allowable heatsink temperature for VS-SD1100C16L at full 1400 A average current?
The maximum allowable heatsink temperature for VS-SD1100C16L is 55 °C when operating at its rated 1400 A average forward current with double-side cooling. This value is specified in the datasheet under "Maximum average forward current at heatsink temperature" and assumes DC or 180° conduction with thermal resistance RthJ-hs = 0.038 K/W. Exceeding 55 °C requires linear derating per the conduction-angle curves in Figures 3 and 4.
Does VS-SD1100C16L support single-side cooling, and what is its IF(AV) in that configuration?
Yes, VS-SD1100C16L supports single-side cooling, with a reduced average forward current rating of 795 A at 55 °C heatsink temperature. This is documented in the "Maximum average forward current" table under "Double side (single side) cooled" and reflects the higher thermal resistance (RthJ-hs = 0.076 K/W) in that mounting mode. Designers must verify heatsink interface quality and thermal paste coverage to achieve this rating.
What is the forward voltage drop of VS-SD1100C16L under typical operating conditions?
The forward voltage drop of VS-SD1100C16L is 1.31 V at 1500 A peak, 10 ms sinusoidal pulse, and junction temperature TJ = 180 °C. At lower currents and temperatures, VF is lower: VF(TO)1 = 0.78 V and rf1 = 0.35 mΩ define the low-current region, while VF(TO)2 = 0.94 V and rf2 = 0.26 mΩ apply above π × IF(AV). These values enable precise conduction loss calculation in system-level thermal models.
Is VS-SD1100C16L pin-compatible with other B-43 diodes such as VS-SD1200C16L?
Yes, VS-SD1100C16L is mechanically and electrically pin-compatible with VS-SD1200C16L - both use identical B-43 hockey PUK packaging, Anode/Cathode terminal layout, mounting hole pattern, and 42 mm diameter interface. No PCB or heatsink redesign is required when upgrading to the higher-current VS-SD1200C16L, provided thermal and electrical margins support the increased IF(AV) = 1600 A rating.
What is the end-of-life status of VS-SD1100C16L, and are alternatives supported by Vishay?
VS-SD1100C16L is scheduled for end-of-life in December 2024, as confirmed in the official Vishay document #93535 (Revision: 09-Jan-2025). Vishay recommends contacting [email protected] or regional support teams for qualified alternative solutions. Aetrix Electronics provides transition support including cross-reference guidance, last-time buy planning, and validated replacements such as VS-SD1200C16L for enhanced current capability.
