Product details
Overview
MBR20100CT-E1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier rated for 100 V reverse voltage, 10 A average forward current per diode leg (20 A total), and 0.85 V max forward voltage at +25°C. It delivers low switching losses and low noise in high-frequency switch-mode power supplies, with a +150°C junction temperature rating and guard-ring stress protection.
For engineers reviewing the MBR20100CT-E1 datasheet, MBR20100CT-E1 pinout, MBR20100CT-E1 application, or MBR20100CT-E1 equivalent, key selection criteria include its dual-diode TO-220-3 (2) package configuration, thermal resistance of 2.5°C/W (junction-to-case), surge capability up to 150 A, and RoHS-compliant green packaging.
Technical Context
This device integrates two independent Schottky diodes in a single common-cathode configuration, enabling synchronous rectification or dual-output DC/DC conversion. Its low VF and fast recovery eliminate minority-carrier storage delay, making it suitable for >100 kHz SMPS topologies where conduction and switching losses must be minimized.
The TO-220-3 (2) package features isolated anode terminals (Pin 1 and Pin 3) and a shared cathode (Pin 2), with internal guard-ring structure enhancing ruggedness against transient overvoltage and thermal stress. Thermal performance is optimized for heatsink mounting, supported by RθJC = 2.5°C/W and RθJA = 60°C/W under standard conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode leg; defines safe operating margin in 48 V–72 V output rails. |
| IF(AV) per leg | 10 A - Continuous DC forward current rating per diode at TC = +122°C; supports 20 A total dual-leg output rectification. |
| VF (max) | 0.85 V @ 10 A, +25°C - Low conduction loss reduces power dissipation and improves efficiency in high-current secondary-side rectification. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Ultra-low leakage preserves regulation accuracy and minimizes standby power in offline adapters. |
| IFSM | 150 A - Non-repetitive surge current handling enables robust startup and fault tolerance in 12 V–48 V industrial power systems. |
| TJ(max) | +150°C - High junction temperature rating allows operation in compact, thermally constrained enclosures without derating. |
| RθJC | 2.5°C/W - Junction-to-case thermal resistance enables effective heat transfer to external heatsinks in TO-220-3 (2) mounting. |
Pinout & Package
MBR20100CT-E1 is housed in a TO-220-3 (2) package: molded plastic case with matte tin–annealed copper leadframe, UL 94V-0 flammability rating, and 1.9 g mass. Pins are arranged in a front-view layout with isolated anodes and common cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 (A1) | Independent input terminal for first diode leg; electrically isolated from Pin 3 to support dual-output or phase-split configurations. |
| Pin 2 | Cathode (K) | Common cathode node for both diodes; serves as primary output reference and thermal path to heatsink via metal tab. |
| Pin 3 | Anode 2 (A2) | Independent input terminal for second diode leg; enables symmetrical current sharing in dual-channel designs. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.85 V max @ 10 A ensures <1.5 W conduction loss per leg at full load, critical for >90% efficiency in 48 V telecom PSUs. |
| Guard-ring protected junction | Enhances ruggedness against dv/dt-induced avalanche and ESD transients (>400 V MM, >8 kV HBM), improving field reliability. |
| High surge current rating | 150 A non-repetitive IFSM withstands inrush and short-circuit events in server VRMs and industrial motor drives. |
| Pb-free & halogen-free "Green" construction | RoHS 2 compliant (2011/65/EU) with <900 ppm Br/Cl and <1000 ppm Sb; meets automotive and medical environmental mandates. |
| +150°C operating junction temperature | Enables use in sealed enclosures or high-ambient environments (e.g., outdoor power converters) without forced cooling. |
Applications

IC Role / Device Role / Timing Role: Fast-switching Schottky rectifier minimizing switching node oscillation in quasi-resonant flyback topologies. Use Value: Zero reverse recovery charge eliminates snubber losses and simplifies EMI filter design versus PN diodes. |
Use Scenario: Auxiliary 12 V supply rectification in EV on-board chargers exposed to under-hood ambient temperatures up to +105°C. IC Role / Device Role / Timing Role: High-TJ-rated dual Schottky supporting continuous operation at +150°C junction with minimal derating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20BQ100PBF | Same 100 V / 10 A per leg rating but TO-220AC package with single-anode pinout (not common-cathode); VF = 0.72 V @ 10 A. | Requires PCB redesign for anode routing; better for single-output designs; lower VF improves light-load efficiency. | Select when optimizing for lowest conduction loss in single-rail systems and layout permits pinout change. |
| ON Semiconductor MBR20100CT | Identical electrical specs and TO-220-3 (2) pinout, but legacy Pb-based finish (non-RoHS); RθJC = 2.7°C/W. | Not suitable for new designs targeting RoHS 2 or automotive AEC-Q200 compliance; identical thermal/mechanical fit. | Use only for legacy repair or drop-in replacement where RoHS exemption applies and traceability allows. |
Compared with VS-20BQ100PBF and ON Semi's MBR20100CT, the MBR20100CT-E1 uniquely combines RoHS 2/green compliance, common-cathode topology, and 2.5°C/W thermal resistance-making it optimal for new dual-output, high-reliability industrial and telecom power designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The MBR20100CT-E1 supports continuous operation up to TC = +122°C for full 10 A per leg rating, verified per datasheet Figure 3. Derating begins linearly above this point, reaching zero current at +150°C junction temperature. Heatsink design must maintain TC ≤ +122°C under worst-case load and ambient conditions.
Can MBR20100CT-E1 replace a single 20 A Schottky in a single-output design?
No-it is a dual 10 A common-cathode device, not a single 20 A diode. Using only one anode leg forfeits half the die area and increases thermal resistance per amp. For single-output 20 A applications, select a true 20 A single-die Schottky like MBR20100CT (TO-220AC) or equivalent.
Is the TO-220-3 (2) package electrically insulated?
No-the metal tab (connected to Pin 2, cathode) is electrically active and not isolated. Electrical isolation requires insulating hardware (e.g., shoulder washers, mica pads) when mounting to grounded heatsinks. The datasheet specifies no internal insulation between tab and cathode.
Does MBR20100CT-E1 require a minimum load or snubber circuit?
No snubber is required due to zero reverse recovery charge. However, a small RC snubber (e.g., 10 Ω + 100 pF) across each anode–cathode may suppress high-frequency ringing in ultra-fast switching (>1 MHz) layouts. No minimum load is specified-operation down to zero load is permitted.
