Product details
Overview
MBR10H100-E3/45 from Vishay General Semiconductor is a high-voltage Schottky rectifier in TO-220AC package, rated for 100 V repetitive peak reverse voltage (VRRM), 10 A average forward current (IF(AV)), and 250 A non-repetitive surge (IFSM). It delivers low forward voltage drop (0.64 V at 10 A, 125 °C) and ultra-low leakage (4.5 µA at 25 °C), enabling high-efficiency operation in switching power supplies and DC/DC converters.
For engineers reviewing the MBR10H100-E3/45 datasheet, MBR10H100-E3/45 pinout, MBR10H100-E3/45 application, or MBR10H100-E3/45 equivalent, key selection criteria include thermal resistance (RθJC = 2.7 °C/W), high-temperature junction rating (TJ max = 175 °C), guardring-enabled overvoltage protection, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This device uses high-barrier Schottky technology to suppress thermally induced leakage and sustain stable conduction up to 175 °C junction temperature. Its single-diode configuration, TO-220AC mechanical outline, and 2.7 °C/W junction-to-case thermal resistance support direct heatsink mounting without isolation hardware.
The MBR10H100-E3/45 operates with fast recovery (dV/dt = 10,000 V/µs) and high-frequency capability due to low junction capacitance and absence of minority-carrier storage. Guardring integration provides robust transient overvoltage tolerance beyond standard VRRM rating, critical for flyback and freewheeling applications with inductive kickback.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in rectifier and polarity protection circuits. |
| IF(AV) | 10 A - Average forward current at case temperature ≤ 100 °C; determines continuous power handling in SMPS output stages. |
| VF | 0.64 V @ 10 A, 125 °C - Low conduction loss reduces heat generation and improves system efficiency at elevated temperatures. |
| IR | 4.5 µA @ 100 V, 25 °C - Ultra-low reverse leakage minimizes standby power loss in battery-backed or energy-sensitive systems. |
| IFSM | 250 A @ 8.3 ms - High surge rating enables reliable operation during startup inrush or load-dump transients. |

Package: TO-220AC - Insulated tab, single-ended heatsink-mountable plastic package with two leads. Meets UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input terminal for forward conduction path | Connected to input source (e.g., transformer secondary or switch node); must be routed with low-inductance layout for high-frequency stability. |
| Pin 2 (Cathode) | Output terminal for forward conduction path | Delivers rectified output to filter capacitor or load; serves as reference node for gate drive or feedback sensing in synchronous topologies. |
| Heatsink Tab (K) | Electrically connected to cathode (Pin 2) | Provides primary thermal path to external heatsink; requires electrically insulating mounting hardware if cathode is not at chassis ground potential. |
Key Features
| Feature | Design Value |
|---|---|
| High-barrier Schottky technology | Enables stable 175 °C operation with <5 µA leakage at 25 °C and <6 mA at 125 °C-critical for high-reliability industrial power supplies. |
| Integrated guardring | Provides intrinsic overvoltage clamping beyond VRRM, eliminating need for external TVS in flyback snubberless designs. |
| Low thermal resistance (RθJC = 2.7 °C/W) | Allows direct bolt-down heatsinking without thermal interface material in many 10 A applications, reducing BOM count and assembly cost. |

IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency AC from transformer secondary into regulated DC output. Use Value: 0.64 V VF at 125 °C reduces conduction loss by ~35% vs. standard silicon diodes, directly improving full-load efficiency and easing thermal design. |
Use Scenario: Freewheeling path in buck, boost, and flyback converters where inductor current must recirculate during switch-off phase. IC Role / Device Role / Timing Role: Fast-recovery path preventing voltage spikes across power MOSFETs during turn-off transitions. Use Value: 10,000 V/µs dV/dt rating and zero minority-carrier storage enable clean commutation at >1 MHz, minimizing EMI and gate driver stress. |
| Polarity Protection Circuit | Industrial Motor Drive Snubber |
|
Use Scenario: Reverse-voltage blocking in 24–48 V DC input rails for PLC I/O modules, sensors, and fieldbus interfaces. IC Role / Device Role / Timing Role: Series-connected anode-in protection diode ensuring system integrity against accidental battery reversal or miswiring. Use Value: 4.5 µA reverse leakage at 25 °C ensures <1 mW standby loss in always-on systems; guardring prevents latch-up during 100 V transients. |
Use Scenario: Clamp diode across IGBT collector-emitter in 3–10 kW variable-frequency drives handling inductive motor loads. IC Role / Device Role / Timing Role: Passive snubber absorbing turn-off energy and limiting dv/dt stress on main switching devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS10H100CG | Same VRRM (100 V), IF(AV) (10 A), TO-220AC package; higher VF (0.75 V @ 10 A, 25 °C) and lower IFSM (200 A). | Less suitable for high-temperature or high-surge environments; acceptable where ambient stays <85 °C and inrush is limited. | Select when cost sensitivity outweighs thermal margin requirements and surge immunity is secondary. |
| ON Semi MUR10100CT | Ultrafast silicon rectifier (not Schottky); higher VF (1.2 V), higher IR (50 µA), but higher TJ max (175 °C) and same IFSM. | Used where reverse recovery noise must be avoided (e.g., near RF sections); trades efficiency for EMI robustness. | Select only when Schottky leakage or EMI from soft recovery is unacceptable-requires re-evaluation of thermal design due to +0.56 V higher VF. |
Compared with STPS10H100CG and MUR10100CT, the MBR10H100-E3/45 offers the lowest conduction loss at elevated temperature and highest surge tolerance among the three, making it optimal for thermally constrained or high-reliability industrial power conversion where efficiency and ruggedness are prioritized.

FAQ
What is the maximum junction temperature rating for the MBR10H100-E3/45?
The MBR10H100-E3/45 has a maximum junction temperature (TJ) of 175 °C, verified per Vishay's thermal characterization and supported by its high-barrier Schottky construction. This rating enables reliable operation in industrial control cabinets, enclosed LED drivers, and automotive under-hood power modules where ambient temperatures exceed 105 °C. The MBR10H100-E3/45 maintains specified leakage and forward voltage performance up to this limit.
Is the MBR10H100-E3/45 pin-compatible with other TO-220AC Schottky rectifiers?
Yes-the MBR10H100-E3/45 uses standard TO-220AC mechanical dimensions and pinout: Pin 1 = Anode, Pin 2 = Cathode, Heatsink Tab = Cathode. It is mechanically interchangeable with industry-standard 10 A, 100 V TO-220AC Schottky rectifiers such as STPS10H100CG and ON Semi SB10100. However, electrical differences in VF, IR, and IFSM require validation in the target circuit before substitution.
Does the MBR10H100-E3/45 require thermal interface material when mounted to a heatsink?
No-the MBR10H100-E3/45's TO-220AC package features an insulated tab and is designed for direct bolt-down heatsinking. With RθJC = 2.7 °C/W, typical thermal performance is achieved using only mechanical pressure (≤10 in-lbs torque) and clean metal-to-metal contact. Thermal interface material is optional and only recommended if surface flatness or oxide layer concerns exist-no dielectric isolation pad is needed since the tab is electrically tied to the cathode.
What is the reverse leakage current specification for the MBR10H100-E3/45 at 125 °C?
At 125 °C junction temperature and rated VR = 100 V, the MBR10H100-E3/45 exhibits a maximum reverse leakage current (IR) of 6.0 mA, as specified in Vishay's Electrical Characteristics table. This value reflects the device's high-barrier design trade-off: while leakage increases with temperature, it remains significantly lower than conventional silicon rectifiers at the same condition-enabling stable operation in hot-running power supplies.
Can the MBR10H100-E3/45 be used in place of a standard silicon rectifier like the 1N5408?
No-the MBR10H100-E3/45 is not a drop-in replacement for general-purpose silicon rectifiers such as the 1N5408. While both are TO-220AC packaged, the MBR10H100-E3/45 is a Schottky device with 100 V VRRM, whereas the 1N5408 is a 1000 V silicon rectifier. Substituting the MBR10H100-E3/45 in high-voltage AC line applications would result in catastrophic failure. It is intended only for low-VF, high-frequency DC applications where its 100 V rating is sufficient.
