Product details
Overview
MBR20100CT-1 from Vishay is a center-tap dual Schottky rectifier optimized for high-temperature operation (TJ = 150 °C), with 2 × 10 A average forward current per leg, 100 V reverse voltage rating, and low 0.70 V forward voltage at 10 A and 125 °C - used in switching power supplies, DC/DC converters, and reverse battery protection circuits.
For engineers reviewing the MBR20100CT-1 datasheet, MBR20100CT-1 pinout, MBR20100CT-1 application, or MBR20100CT-1 equivalent, key selection criteria include thermal resistance (RthJC = 2.0 °C/W per leg), surge capability (IFSM = 850 A), junction capacitance (CT = 400 pF), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal in a single TO-262 package, enabling center-tapped configuration for full-wave rectification without external wiring. Its proprietary barrier technology minimizes reverse leakage at elevated temperatures while maintaining fast recovery (dV/dt = 10,000 V/µs) and low forward slope resistance (rt = 15.8 mΩ).
The MBR20100CT-1 operates across -65 °C to +150 °C junction temperature range, with thermal impedance optimized for direct heatsink mounting (RthCS = 0.50 °C/W typical). It supports high-frequency switching applications due to negligible minority-carrier storage and absence of reverse recovery charge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 10 A - supports continuous 10 A DC output per anode leg at TC = 133 °C |
| VRRM | 100 V - maximum non-repetitive peak reverse voltage; defines safe blocking margin in 48 V–72 V bus systems |
| VF @ 10 A, 125 °C | 0.70 V - enables <1.5 W conduction loss per leg at rated current, reducing heatsink requirements |
| RthJC per leg | 2.0 °C/W - allows direct thermal path to heatsink; enables 20 W dissipation before reaching 150 °C junction limit |
| IFSM | 850 A - withstands short-circuit surges up to 5 µs, supporting robust overcurrent protection design |
| CT @ 5 V | 400 pF - limits high-frequency displacement current; suitable for ≤1 MHz switching topologies |

Pinout & Package
MBR20100CT-1 uses the TO-262 (I²PAK) package with three terminals: Pin 1 (Anode 1), Pin 2 (Common Cathode), Pin 3 (Anode 2). The base-isolated plastic case provides mechanical strength and moisture resistance per IEC 61249-2-21 halogen-free compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode Leg 1 | Connects to input AC or switched node for first half-cycle conduction path |
| Pin 2 | Common Cathode | Shared output node for both legs; connects to load/positive rail in center-tap rectifier topology |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS20H100CG | TO-247 package; higher IFSM (1200 A); same VRRM (100 V) and IF(AV) (10 A/leg) | Requires larger PCB footprint and different mounting hardware; better suited for higher surge immunity needs | Select when surge robustness exceeds thermal constraints, or when TO-247 heatsink infrastructure already exists |
| ON Semiconductor MBR20100CT | Same TO-262 package and pinout; identical electrical specs but not AEC-Q101 qualified | Lacks automotive qualification; limited to industrial/commercial temperature range (-65 °C to +125 °C) | Select for cost-sensitive non-automotive applications where AEC-Q101 is not required |
Compared with STPS20H100CG and ON Semiconductor MBR20100CT, the MBR20100CT-1 uniquely combines AEC-Q101 qualification, TO-262 form factor, and 150 °C operation - making it the only choice for space-constrained automotive power modules requiring extended temperature reliability.

FAQ
What is the maximum junction temperature rating for the MBR20100CT-1?
The MBR20100CT-1 is rated for continuous operation up to 150 °C junction temperature, validated per AEC-Q101 stress testing. This enables reliable use in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105 °C. Derating curves in the datasheet (Document Number 94306) define allowable case temperature versus average forward current per leg.
Does the MBR20100CT-1 have a center-tap configuration and how is it implemented physically?
Yes, the MBR20100CT-1 implements a center-tap configuration via a shared cathode terminal (Pin 2), with separate anodes (Pins 1 and 3) forming two independent Schottky diodes. This internal common-cathode structure eliminates external wiring for full-wave rectification, reducing layout complexity and parasitic inductance. The TO-262 package maintains electrical isolation between anode leads while thermally coupling both dies to the common tab.
Is the MBR20100CT-1 RoHS and halogen-free compliant?
Yes, the MBR20100CT-1 is RoHS-compliant per Directive 2002/95/EC and halogen-free per IEC 61249-2-21. Its high-purity, high-temperature epoxy encapsulation meets both environmental standards without compromising mechanical strength or moisture resistance. The "PbF" suffix in the ordering code (MBR20100CT-1PbF) explicitly denotes lead-free terminations.
What is the thermal resistance from junction to case for each leg of the MBR20100CT-1?
The MBR20100CT-1 has a maximum thermal resistance of 2.0 °C/W per leg from junction to case (RthJC) under DC operation. This value applies independently to each diode leg and assumes proper mounting with smooth, greased interface to the heatsink. Typical RthCS (case-to-heatsink) is 0.50 °C/W, enabling efficient thermal management in high-power density designs.
How does the MBR20100CT-1 compare to standard silicon rectifiers in terms of reverse recovery behavior?
The MBR20100CT-1 exhibits no reverse recovery charge (Qrr ≈ 0) due to its Schottky barrier construction, unlike standard silicon PN-junction rectifiers. This eliminates reverse recovery losses and associated EMI, enabling clean switching at frequencies up to 1 MHz. Its dV/dt rating of 10,000 V/µs further ensures stable operation during fast voltage transients without spurious turn-on.
