Product details
Overview
VS-VSKCS220/030 from Vishay Semiconductors is a 30 V, 220 A average current Schottky rectifier power module in AAP Gen 7 (TO-240AA) package with common-cathode dual-diode configuration. It delivers low forward voltage drop (0.57 V at 110 A, 125 °C), operates up to 150 °C junction temperature, and is optimized for high-current industrial switching power supplies and UPS systems.
For engineers reviewing the VS-VSKCS220/030 datasheet, VS-VSKCS220/030 pinout, VS-VSKCS220/030 application, or VS-VSKCS220/030 equivalent, key selection criteria include its 0.52 °C/W thermal resistance per leg, 18 kA non-repetitive surge rating, common-cathode topology for half-bridge freewheeling, and UL E78996 approval for safety-critical installations.
Technical Context
This dual-Schottky module uses exposed direct-bonded copper substrate for enhanced thermal conduction and features a simplified internal structure with minimized thermal interfaces. Its barrier technology enables stable reverse leakage performance (650 mA at 125 °C, rated VR) and reliable operation up to 150 °C TJ.
The device supports high-frequency switching with 10,000 V/μs dV/dt capability and low parasitic inductance (7.0 nH typical). Its TO-240AA-compatible mechanical outline includes M5 mounting screws and is designed for direct busbar integration and heatsink mounting with thermal compound.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY220-030 | Same 30 V / 220 A rating but TO-247-3L discrete package; higher RthJC (1.2 °C/W); no common-cathode integration | Requires external cathode tie and two separate footprints; less compact than module solution | Preferred when board space permits discrete layout and thermal management uses individual heatsinks |
| IXYS MBR22030CT | 30 V / 220 A common-cathode TO-247AC; VF = 0.72 V @ 110 A, 25 °C; RthJC = 0.75 °C/W; no UL recognition | Lacks UL E78996 and 150 °C rating; lower surge rating (12 kA) | Suitable for cost-sensitive industrial designs where safety certification and extreme thermal margin are not required |
Compared with VSKY220-030 and MBR22030CT, the VS-VSKCS220/030 offers superior thermal performance (0.52 °C/W), integrated common-cathode layout, and UL safety approval-making it optimal for space-constrained, high-reliability, and safety-certified power systems.

FAQ
What is the maximum junction temperature rating for the VS-VSKCS220/030?
The VS-VSKCS220/030 is rated for a maximum junction temperature of +150 °C, enabling operation in high-ambient environments such as sealed industrial enclosures or liquid-cooled systems. This rating is validated across its full current range and supported by its exposed DBC substrate and low RthJC of 0.52 °C/W per leg. The VS-VSKCS220/030 maintains stable reverse leakage (650 mA at 125 °C) and forward voltage characteristics up to this limit.
Does the VS-VSKCS220/030 have UL safety certification?
Yes, the VS-VSKCS220/030 carries UL recognition under file E78996, confirming compliance with UL 60950-1 and UL 62368-1 for insulation, flammability, and dielectric strength. This certification applies specifically to the AAP Gen 7 package construction and validates its use in safety-critical end equipment including UPS, medical-grade PSUs, and industrial control systems. The VS-VSKCS220/030 documentation explicitly references this file number.
What is the thermal resistance from junction to case per leg for the VS-VSKCS220/030?
The VS-VSKCS220/030 has a maximum thermal resistance of 0.52 °C/W from junction to case per leg under DC operation. This value is measured per diode leg and reflects the efficiency of its direct-bonded copper substrate in transferring heat to the baseplate. When mounted with thermal compound on a flat heatsink, the VS-VSKCS220/030 achieves a total RthCS of 0.1 °C/W per module, enabling high-power dissipation with minimal temperature rise.
Can the VS-VSKCS220/030 be used in parallel configurations?
Yes, the VS-VSKCS220/030 supports parallel operation due to its positive temperature coefficient of forward voltage, which promotes current sharing between modules. For reliable paralleling, Vishay recommends matched mounting torque (4 Nm), uniform thermal interface material application, and symmetrical busbar layout to minimize inductance imbalance. Each VS-VSKCS220/030 module contributes 220 A average current capacity in such configurations.
What is the non-repetitive surge current rating for the VS-VSKCS220/030?
The VS-VSKCS220/030 is rated for a non-repetitive peak surge current of 18,000 A with a 5 μs sine pulse, tested under rated VRRM and following any rated load condition. This rating supports robust protection against line transients, motor startup surges, and battery short circuits in UPS and welding applications. The VS-VSKCS220/030 also specifies 2000 A for 10 ms sine pulses, providing design margin for longer-duration overload events.
