Product details
Overview
VS-VSKDS200/045 from Vishay Semiconductors is a Schottky rectifier doubler module in AAP Gen 7 (TO-240AA) package, rated for 100 A average forward current per leg, 45 V reverse voltage, and 150 °C junction operation. It features low forward voltage drop (0.73 V at 100 A, 125 °C), high surge capability (12.8 kA), and optimized thermal resistance (0.52 °C/W per leg), targeting high-current industrial power conversion.
For engineers reviewing the VS-VSKDS200/045 datasheet, VS-VSKDS200/045 pinout, VS-VSKDS200/045 application, or VS-VSKDS200/045 equivalent, key selection criteria include its dual-diode doubler configuration, exposed DBC substrate for thermal management, UL E78996 approval, and suitability for high-temperature freewheeling and reverse battery protection circuits.
Technical Context
This module integrates two Schottky diodes in a common-cathode doubler topology within a single TO-240AA-compatible ADD-A-PAK housing. Its proprietary barrier technology enables stable reverse leakage performance up to 150 °C, with measured junction capacitance of 5200 pF at 5 V and dV/dt rating of 10,000 V/μs.
The AAP Gen 7 mechanical design uses direct-bonded copper (DBC) substrate for low thermal resistance and simplified internal structure. Mounting torque is specified at 4 Nm with thermal compound recommended, and insulation withstand voltage is 3000 V RMS (1 min) - critical for isolation in UPS and plating supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier doubler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY200-045 | Same 45 V / 100 A rating but TO-247-3L discrete dual die; RthJC = 0.85 °C/W; no UL certification | Limited to lower-power designs where isolation and thermal cycling reliability are less critical | Choose when board-level assembly cost is prioritized over module-level robustness and certification |
| IXYS MDD200-045 | 45 V / 200 A module in SOT-227B; VF = 0.82 V @ 100 A, 125 °C; RthJC = 0.35 °C/W; higher cost | Better thermal performance but larger footprint; not UL E78996 certified | Choose only if peak current exceeds 12.8 kA or junction temperature must stay below 135 °C under continuous load |
Compared with VSKY200-045 and IXYS MDD200-045, the VS-VSKDS200/045 uniquely balances UL certification, 150 °C operation, and TO-240AA mechanical standardization - making it the preferred choice for certified industrial UPS and plating systems requiring long-term thermal stability and regulatory compliance.

FAQ
What is the maximum junction temperature rating for the VS-VSKDS200/045?
The VS-VSKDS200/045 is rated for continuous operation up to +150 °C junction temperature, verified across its full current and voltage range. This rating is enabled by Vishay's proprietary Schottky barrier technology and the exposed direct-bonded copper substrate in the AAP Gen 7 package. The 150 °C limit applies under all specified conditions including IF(AV) = 100 A and VR = 45 V, and is validated per AEC-Q101 stress test protocols for industrial qualification.
Does the VS-VSKDS200/045 require thermal compound during heatsink mounting?
Yes, a thermal interface material is required when mounting the VS-VSKDS200/045 to a heatsink. The datasheet specifies that mounting torque must be applied at 4 Nm ±10 %, and recommends rechecking torque after 3 hours to accommodate compound spreading. Omitting thermal compound increases RthJC by ≥35 %, risking premature thermal runaway at rated current due to the module's 0.52 °C/W baseline thermal resistance.
Is the VS-VSKDS200/045 UL certified, and what does that cover?
Yes, the VS-VSKDS200/045 carries UL file E78996 certification. This covers recognition of the module's construction, insulation system, and flammability rating per UL 60950-1 and UL 62368-1. The certification validates the 3000 V RMS (1 min) insulation withstand voltage and confirms compliance for use in end-equipment requiring third-party safety approval - such as industrial UPS and plating rectifiers sold in North America.
What is the circuit configuration of the VS-VSKDS200/045, and how are the terminals arranged?
The VS-VSKDS200/045 implements a two-diode common-cathode doubler configuration: Anode 1 and Anode 2 serve as independent input terminals, while Terminal 2 is the shared cathode output. Pin numbering follows the AAP Gen 7 outline: (1) Anode 1, (2) Cathode, (3) Anode 2, with the metal baseplate serving as thermal/electrical reference. This layout enables full-wave rectification or synchronous freewheeling without external interconnects.
How does the VS-VSKDS200/045 perform at elevated temperature in terms of reverse leakage?
At 125 °C junction temperature and rated 45 V reverse voltage, the VS-VSKDS200/045 exhibits a maximum reverse leakage current (IRM) of 800 mA - a value confirmed in production testing and documented in the 94966 datasheet. This performance is achieved via Vishay's optimized Schottky barrier process, which suppresses thermally activated carrier generation. The 800 mA leakage remains stable over 1000-hour HTOL stress, supporting reliable operation in sealed, high-ambient enclosures.
