Product details
Overview
MBRB10100CT from Diodes Incorporated is a dual common-cathode 100 V, 5 A per leg Schottky barrier rectifier in TO263AB (D2PAK) package, featuring 0.84 V max forward voltage at 5 A and 0.1 mA max reverse leakage at 100 V and +25°C. It serves as polarity protection, recirculating, or switching diode in DC-DC converters and power supply output stages.
For engineers reviewing the MBRB10100CT datasheet, MBRB10100CT pinout, MBRB10100CT application, or MBRB10100CT equivalent, key selection criteria include per-leg forward current rating (5 A), peak repetitive reverse voltage (100 V), thermal resistance (5 °C/W junction-to-case), surge capability (110 A IFSM), and RoHS-compliant green packaging.
Technical Context
This dual Schottky rectifier integrates two independent anode terminals sharing one cathode terminal, enabling synchronous half-wave rectification or dual-path DC output management. Its guard ring die construction enhances transient immunity, while low VF minimizes conduction loss in high-frequency switching topologies.
Rated for operation from –55°C to +175°C, it delivers stable performance under thermal stress with typical RθJA of 20 °C/W on a 2-inch Al board. The device meets AEC-Q101 for high-reliability commercial applications but is not qualified for automotive safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each anode can block without breakdown |
| IO (per leg) | 5 A - Continuous average forward current per anode at TA = +25°C, derated above 25°C |
| VF (max) | 0.84 V @ 5 A, +25°C - Limits conduction loss to ≤4.2 W per leg at full load |
| IR (max) | 0.1 mA @ 100 V, +25°C - Ensures minimal standby power loss in hold-up or bias circuits |
| IFSM | 110 A - Withstands single half-sine surge (8.3 ms), supporting inrush current handling |
| RθJC | 5 °C/W - Enables direct heatsink mounting for efficient thermal management in compact layouts |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, 3-terminal plastic case with exposed copper thermal pad (cathode-connected). Dimensions conform to Type B/C variants per Diodes Inc. outline drawings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input path for first rectifier leg | Accepts AC or switched DC input; electrically isolated from Anode 2 |
| Anode 2 (Pin 2) | Input path for second rectifier leg | Enables dual-output or parallel-input configuration; shares cathode with Pin 1 |
| Cathode (Pin 3 / Tab) | Common output node | Thermally and electrically connected to large exposed metal tab; must be soldered to PCB copper pour for thermal and electrical integrity |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient voltage immunity without external clamping components |
| Low VF Schottky architecture | Reduces forward power dissipation by ~40% vs. comparable silicon rectifiers at 5 A |
| AEC-Q101 qualification | Validates reliability for industrial and extended-temperature commercial environments |
| Halogen- and antimony-free "Green" compound | Meets <900 ppm Br/Cl and <1000 ppm Sb; supports environmental compliance programs |
Applications
| DC-DC Converter Output Rectification | Polarity Protection Circuit |
|---|---|
Use Scenario: Secondary-side rectification in 12 V–48 V isolated flyback or forward converters powering telecom or server boards. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replacing center-tapped transformer + single diode or discrete dual-diode solutions. Use Value: 0.84 V VF reduces conduction loss by ≥1.5 W per leg vs. 1.1 V Si diodes, improving efficiency at 5 A load. | Use Scenario: Reverse-voltage blocking at main DC input of industrial PLC modules operating from 24 V rails. IC Role / Device Role / Timing Role: Polarity protection diode placed in series with input power rail before bulk capacitance. Use Value: 100 V VRRM provides 4× margin over 24 V nominal input; low IR prevents battery drain during standby. |
| Motor Drive Freewheeling Path | Re-Circulating Diode in Solenoid Drivers |
Use Scenario: Flyback path for brushed DC motor H-bridge outputs in HVAC actuators or robotic joints. IC Role / Device Role / Timing Role: Recirculating diode across motor winding to clamp inductive kickback during PWM off-time. Use Value: 110 A IFSM handles peak flyback currents exceeding 50 A; fast recovery avoids cross-conduction losses. | Use Scenario: Energy recirculation path for 24 V solenoid valves in factory automation I/O modules. IC Role / Device Role / Timing Role: Switching diode placed across solenoid coil to manage turn-off energy. Use Value: Low VF ensures rapid coil de-energization (<10 µs decay time); TO263AB thermal pad sustains repeated pulse duty cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR10100CT | Same 100 V/5 A per leg rating; VF = 0.85 V max at 5 A; RθJC = 5.5 °C/W | Slightly higher thermal resistance limits power density in thermally constrained layouts | Select when sourcing from Vishay-authorized channels or requiring alternate qualification documentation |
| ON Semiconductor MBR10100CT | Identical electrical specs; uses TO220AC package instead of TO263AB; no exposed thermal pad | Lacks integrated heatsink interface; requires external heatsink for >3 A continuous operation | Prefer for through-hole assembly or legacy board compatibility where surface-mount thermal management is impractical |
Compared with VS-MBR10100CT and MBR10100CT, the MBRB10100CT offers superior thermal performance via its TO263AB thermal pad and tighter VF tolerance, making it optimal for high-density, surface-mount power supplies where board space and thermal headroom are constrained.

FAQ
What is the maximum junction temperature for continuous operation?
The MBRB10100CT has an operating junction temperature range of –55°C to +175°C. For reliable continuous operation, junction temperature must remain below +175°C under worst-case ambient and power dissipation conditions, verified using RθJC = 5 °C/W and measured case temperature.
Is the cathode terminal electrically connected to the thermal pad?
Yes - the cathode (Pin 3) is internally bonded to the exposed metal thermal pad on the underside of the TO263AB package. This pad must be soldered to a PCB copper pour tied to the system ground or output rail to ensure both thermal conduction and correct circuit functionality.
Does this part support lead-free reflow soldering?
Yes - the MBRB10100CT features matte tin annealed over copper leadframe and complies with J-STD-020 moisture sensitivity Level 1. It is qualified for standard Pb-free reflow profiles up to 260°C peak temperature, with no pre-bake required.
Can MBRB10100CT replace a single 10 A Schottky in parallel configurations?
No - the MBRB10100CT is rated for 5 A per leg (10 A total only if both legs operate independently with separate thermal paths). Parallel use of both anodes for a single 10 A path violates SOA limits due to unequal current sharing and thermal coupling; a dedicated 10 A single-die device is required instead.
