Product details
Overview
MBR10100CT-E1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 5 A average forward current per diode leg, 0.85 V max forward voltage at +25°C, and 0.1 mA max reverse leakage at +25°C. It serves as output rectification in switch-mode power supplies requiring low switching losses and high-frequency operation.
For engineers reviewing the MBR10100CT-E1 datasheet, MBR10100CT-E1 pinout, MBR10100CT-E1 application, or MBR10100CT-E1 equivalent, this device is selected for medium-voltage DC-DC conversion where thermal performance (RθJC = 4.5 °C/W), surge robustness (100 A IFSM), and RoHS-compliant green packaging are critical design requirements.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V/5 A diode elements sharing a single cathode terminal. Its guard-ring structure enhances ruggedness against transient overvoltage stress while maintaining low forward conduction loss across -55°C to +150°C junction temperature range.
The device operates with minimal reverse recovery charge (Qrr ≈ 0 nC) and exhibits dv/dt capability of 10,000 V/µs - enabling stable use in high-frequency flyback and forward converters without snubber networks. Thermal resistance to case (4.5 °C/W) supports direct heatsink mounting in compact industrial power modules.
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 bus-derived SMPS outputs. |
| IF(AV) | 5 A per diode leg - Continuous DC forward current rating at TC = +136°C; enables 10 A total dual-leg output rectification. |
| VF (max) | 0.85 V @ 5 A, +25°C - Low forward drop reduces conduction loss and improves efficiency in high-current, low-voltage secondary-side rectification. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Ultra-low reverse leakage minimizes standby power loss in energy-sensitive AC-DC adapters. |
| IFS M | 100 A - Non-repetitive peak surge current capability; withstands inrush transients during cold-start in offline power supplies. |
| TJ Range | -55°C to +150°C - Wide junction temperature range supports operation in sealed industrial enclosures without active cooling. |
| RθJC | 4.5 °C/W - Measured junction-to-case thermal resistance for TO-220F-3 package; enables predictable heatsink sizing for thermal management. |
Pinout & Package
MBR10100CT-E1 uses the TO-220F-3 package: insulated plastic case with three leads, flanged metal tab (cathode-connected), and matte tin-plated copper leadframe. Mounting requires mechanical isolation from heatsink unless cathode is referenced to ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 (A1) | Anode of Diode Leg 1 | Connects to transformer secondary or switching node; carries full 5 A forward current in half-wave configuration. |
| Lead 2 (K) | Common Cathode | Shared output terminal for both diode legs; must be routed with low-inductance path to bulk capacitor and load return. |
| Lead 3 (A2) | Anode of Diode Leg 2 | Enables dual-output or center-tapped transformer rectification; electrically isolated from A1 but thermally coupled via shared case. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.85 V @ 5 A ensures <0.43 W conduction loss per diode leg at room temperature - critical for >90% efficiency targets. |
| Guard-ring protected junction | Enhances ruggedness against line transients and ESD events (>8 kV HBM), reducing field failure risk in unregulated input stages. |
| High TJ rating | +150°C maximum junction temperature allows operation in confined spaces without derating at ambient up to +85°C with proper heatsinking. |
| Pb-free & Halogen-free | RoHS 3 compliant (2015/863/EU) and "Green" certified (<900 ppm Br/Cl, <1000 ppm Sb); meets automotive and industrial environmental mandates. |
Applications
| AC-DC Adapter Output Rectification | Industrial DC-DC Converter Secondary Side |
|---|---|
|
Use Scenario: 24 V/5 A output stage in universal-input 100–240 VAC adapter for industrial control panels. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replacing fast recovery diodes to reduce switching loss and eliminate reverse recovery noise. Use Value: 0.85 V VF cuts conduction loss by ~35% vs. silicon FRD, improving full-load efficiency from 87% to 90.2% at 50 kHz switching. |
Use Scenario: 12 V/10 A isolated output in 48 V input telecom DC-DC module with synchronous rectification not feasible. IC Role / Device Role / Timing Role: Common-cathode dual rectifier enabling interleaved or dual-winding transformer topology with shared output filter. Use Value: 100 A IFSM withstands 2× inrush surges during hot-swap insertion; RθJC = 4.5 °C/W permits passive heatsinking in 1U chassis. |
| LED Driver Secondary Rectification | Server PSU Hold-Up Capacitor Charging Path |
|
Use Scenario: Constant-current LED driver with 36 V output driving high-brightness arrays in outdoor signage. IC Role / Device Role / Timing Role: High-frequency rectifier in quasi-resonant flyback, operating at 130 kHz with minimal EMI generation. Use Value: Near-zero Qrr eliminates switching spikes that interfere with current-sense accuracy; 0.1 mA IR prevents standby drain on hold-up capacitors. |
Use Scenario: Input-stage rectifier in redundant 12 V server power supply, handling bulk capacitor pre-charge after AC restoration. IC Role / Device Role / Timing Role: Dual-anode configuration allows parallel connection to split surge current between two internal diodes during inrush. Use Value: 100 A IFSM rating exceeds typical 60–80 A pre-charge peaks; TO-220F-3 insulation avoids need for additional creepage barriers. |
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-10BQ100-M3 | Same 100 V/5 A per leg, but TO-263-2 package (RθJC = 2.0 °C/W); VF = 0.82 V @ 5 A, +25°C. | Better thermal performance in surface-mount designs; lacks TO-220F-3's built-in insulation. | Select when PCB space is constrained and heatsinking is via copper pour rather than external heatsink. |
| ON Semiconductor MBR10100CT | Identical electrical specs but TO-220-3 (2) non-insulated package (RθJC = 3.0 °C/W); no flange isolation. | Requires insulating washer for heatsink mounting; higher thermal conductivity but lower safety clearance. | Select when cost sensitivity outweighs isolation requirement and mechanical mounting permits direct case grounding. |
Compared with VS-10BQ100-M3 and MBR10100CT, MBR10100CT-E1 uniquely combines flanged insulation (TO-220F-3), RoHS 3/Green compliance, and verified 4.5 °C/W thermal resistance - making it optimal for safety-critical, thermally dense, and environmentally regulated industrial power designs.

FAQ
What is the thermal resistance from junction to case for MBR10100CT-E1?
The junction-to-case thermal resistance (RθJC) is 4.5 °C/W for the TO-220F-3 package, measured under standard test conditions with the metal tab mounted to a heatsink. This value assumes full contact area and proper mounting torque; actual system-level thermal performance depends on interface material and heatsink fin density.
Can MBR10100CT-E1 replace a single 10 A Schottky diode?
No - MBR10100CT-E1 contains two independent 5 A diodes sharing a common cathode; it is not rated for 10 A continuous current through one anode. For 10 A single-path rectification, use a dedicated 10 A Schottky such as MBR20100CT, which has identical pinout but higher per-leg rating.
Is the TO-220F-3 package electrically insulated?
Yes - the TO-220F-3 variant features an insulated flange: the metal tab is internally isolated from all three leads, allowing direct mounting to a grounded heatsink without shorting the cathode. This differs from standard TO-220-3 (2), where the tab connects to the cathode terminal.
What is the maximum allowable case temperature during continuous operation?
The maximum recommended case temperature is +136°C, derived from the IF(AV) = 5 A rating condition. Exceeding this temperature causes progressive derating of forward current; at +100°C case, the device supports ~7.2 A average current per leg based on thermal resistance and junction limit of +150°C.
