Product details
Overview
VS-VSKJS209/150 from Vishay Semiconductors is a 150 V, 200 A average current, dual common-anode Schottky rectifier power module in AAP Gen 7 (TO-240AA) package. It delivers low forward voltage (0.85 V at 100 A, 125 °C), high surge capability (11,300 A IFSM), and operates up to 175 °C junction temperature. It is optimized for high-current switching power supplies and reverse battery protection.
For engineers reviewing the VS-VSKJS209/150 datasheet, VS-VSKJS209/150 pinout, VS-VSKJS209/150 application, or VS-VSKJS209/150 equivalent, key selection criteria include thermal resistance (0.52 °C/W per leg), reverse leakage (85 mA at 125 °C), junction capacitance (3000 pF), dV/dt rating (10,000 V/μs), and UL approval (E78996).
Technical Context
This dual-diode common-anode Schottky rectifier uses proprietary barrier technology enabling stable operation at 175 °C TJ with low reverse leakage. Its exposed direct-bonded copper substrate yields low RthJC (0.52 °C/W per leg) and supports high-power density mounting on heatsinks.
The module is rated for 150 V DC reverse voltage and handles 200 A average forward current under 50 % duty cycle at TC = 113 °C. It features high dV/dt immunity (10,000 V/μs) and low series inductance (7.0 nH), making it suitable for fast-switching topologies including synchronous rectification and freewheeling paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKJS209/150 | Same die, identical electrical specs; differs only in branding (no "VS-" prefix) | No functional difference; used interchangeably in Vishay documentation and ordering | Select when sourcing from legacy BOMs or distributor stock referencing bare part number |
| VS-VSKJS209/120 | Lower VR = 120 V; same IF(AV), package, and thermal specs | Suitable only where system blocking voltage ≤ 120 V; not safe for 150 V-rated designs | Choose only if design margin permits 30 V lower reverse voltage; verify transient overvoltage limits |
Compared with VS-VSKJS209/150, the VSKJS209/150 offers identical performance and drop-in compatibility, while the VS-VSKJS209/120 trades 30 V blocking capability for potentially lower cost-requiring careful system-level voltage margin analysis before substitution.

FAQ
What is the maximum junction temperature rating for VS-VSKJS209/150?
The VS-VSKJS209/150 is rated for a maximum junction temperature of +175 °C, validated per Vishay's industrial qualification standards. This enables reliable operation in high-ambient environments such as enclosed power cabinets or near heat-generating components. The 175 °C rating is supported by its proprietary Schottky barrier technology and direct-bonded copper substrate, which maintain low leakage and stable VF across the full range.
Does VS-VSKJS209/150 have UL recognition?
Yes, the VS-VSKJS209/150 carries UL recognition file E78996, confirming compliance with UL 60950-1 and UL 62368-1 for use in information technology and audio/video equipment. This certification covers the module's insulation integrity, flammability, and construction - critical for end-product safety approvals in North American markets.
What is the thermal resistance from junction to case per leg for VS-VSKJS209/150?
The VS-VSKJS209/150 has a maximum thermal resistance of 0.52 °C/W per leg (RthJC) under DC operation. This value is measured from each diode junction to the case surface and is essential for calculating junction temperature rise under load. Combined with its 0.1 °C/W typical RthCS, the module supports efficient heat transfer to external heatsinks in high-power applications.
Can VS-VSKJS209/150 be used in reverse battery protection circuits?
Yes, the VS-VSKJS209/150 is explicitly optimized for reverse battery protection, as noted in Vishay's Electrical Description section. Its low reverse leakage (85 mA at 125 °C) and robust 150 V blocking capability make it suitable for automotive and industrial 24 V/48 V battery systems. The common-anode configuration simplifies placement in high-side protection schemes with dual output paths.
What is the forward voltage drop of VS-VSKJS209/150 at 200 A and 25 °C?
The forward voltage drop of VS-VSKJS209/150 is 1.35 V at 200 A and 25 °C, as specified in the Electrical Specifications table. This value reflects total conduction loss across both legs under full-load, room-temperature conditions. At elevated temperatures (e.g., 125 °C), VF drops to 1.13 V at 200 A due to Schottky barrier characteristics, improving efficiency in thermally demanding applications.
