Product details
Overview
VS-MBRB20100CTGPBF from Vishay is a center-tap dual Schottky rectifier in D2PAK package, rated for 2 × 10 A average forward current per leg and 100 V maximum DC reverse voltage, with 0.70 V forward voltage at 10 A and 125 °C junction temperature-optimized for high-efficiency switching power supplies and reverse battery protection circuits.
For engineers reviewing the VS-MBRB20100CTGPBF datasheet, VS-MBRB20100CTGPBF pinout, VS-MBRB20100CTGPBF application, or VS-MBRB20100CTGPBF equivalent, key selection criteria include thermal resistance (2.0 °C/W per leg), low leakage at 150 °C operation, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates two independent Schottky die sharing a common cathode terminal, enabling center-tap configuration for full-wave rectification without external wiring. Its proprietary barrier technology ensures stable reverse leakage <6 mA at 125 °C and <0.10 mA at 25 °C under rated VR.
Designed for high-frequency operation up to 20 kHz square wave, it features low series inductance (8.0 nH) and fast dV/dt capability (10,000 V/μs), minimizing switching losses and EMI in DC-DC converters and synchronous rectifier topologies.
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 |
|---|---|---|---|
| STPS20S100CGY | TO-220AC package, single-diode configuration, 20 A total IF(AV), same 100 V VRRM | Lacks center-tap architecture; requires two devices for full-wave rectification | Preferred where through-hole mounting and discrete layout flexibility outweigh integration benefits |
| ON Semiconductor MBR20100CT | D2PAK package, identical pinout and 2×10 A / 100 V rating, but not AEC-Q101 qualified | Not validated for automotive under-hood use; lower IRM spec (10 mA @ 125 °C) | Suitable for cost-sensitive industrial power supplies where automotive qualification is unnecessary |
Compared with STPS20S100CGY and MBR20100CT, VS-MBRB20100CTGPBF uniquely combines center-tap integration, AEC-Q101 qualification, and 6 mA IRM at 125 °C-making it optimal for space-constrained, high-reliability automotive and industrial rectification where thermal stability and functional integration are prioritized.

FAQ
What is the maximum junction temperature rating for VS-MBRB20100CTGPBF?
The VS-MBRB20100CTGPBF is rated for continuous operation up to +150 °C junction temperature, verified per AEC-Q101 stress testing and supported by its 2.0 °C/W thermal resistance per leg. This allows reliable use in under-hood automotive environments and sealed industrial enclosures without active cooling when mounted on adequate copper area.
Does VS-MBRB20100CTGPBF support full-wave rectification without external components?
Yes, VS-MBRB20100CTGPBF integrates two Schottky die with a shared cathode terminal (pin 2), enabling native full-wave center-tap rectification. Pins 1 and 3 serve as independent anodes, eliminating the need for external diode pairing or wiring-reducing BOM count and layout complexity in DC-DC and AC-DC secondary-side designs.
Is VS-MBRB20100CTGPBF lead-free and halogen-free?
Yes, VS-MBRB20100CTGPBF is fully lead-free (PbF) and halogen-free per JEDEC JS709A standards. Its high-purity, high-temperature epoxy encapsulation meets RoHS Directive 2011/65/EU and supports environmentally compliant manufacturing and end-of-life processing.
What is the forward voltage drop of VS-MBRB20100CTGPBF at 10 A and 125 °C?
The forward voltage drop of VS-MBRB20100CTGPBF is specified at 0.70 V under 10 A DC current and 125 °C junction temperature. This low VF value directly reduces conduction losses to approximately 7 W per leg, improving overall system efficiency and easing thermal design constraints.
How does the guard ring feature improve reliability in VS-MBRB20100CTGPBF?
The guard ring in VS-MBRB20100CTGPBF enhances edge termination robustness, suppressing premature avalanche breakdown and improving resistance to voltage transients and electrostatic stress. This contributes to long-term reliability in automotive and industrial applications subject to repetitive surge events and harsh electrical environments.
