Product details
Overview
MBRB760HE3_B/I from Vishay General Semiconductor is a 60 V, 7.5 A average forward current Schottky barrier rectifier in TO-220AC package, featuring 0.65 V forward voltage at 7.5 A and 125 °C junction temperature, 150 A non-repetitive surge capability, and guardring-enhanced overvoltage protection-used as output rectifier in 12 V/24 V DC/DC converters.
For engineers reviewing the MBRB760HE3_B/I datasheet, MBRB760HE3_B/I pinout, MBRB760HE3_B/I application, or MBRB760HE3_B/I equivalent, key selection criteria include low VF at high temperature, TO-220AC thermal resistance (3.0 °C/W), reverse leakage at 125 °C (50 mA), and compatibility with 275 °C solder bath per JESD 22-B106.
Technical Context
This device implements a single-die, planar Schottky barrier structure with integrated guardring to suppress edge breakdown under transient overvoltage conditions. Its low VF and fast recovery enable high-efficiency operation in switching frequencies up to several hundred kHz without minority-carrier storage delay.
The TO-220AC package provides direct metal-to-heatsink mounting via pin 2 (cathode tab), supporting continuous conduction mode in high-current SMPS outputs. Thermal resistance from junction to case is 3.0 °C/W, enabling 7.5 A average current at TC ≤ 90 °C with standard heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - maximum repetitive reverse blocking voltage; defines safe operating limit in DC/DC converter secondary-side rectification |
| IF(AV) | 7.5 A - average forward current at TC = 25 °C; derates linearly to zero at TC = 150 °C per Fig. 1 |
| VF | 0.65 V @ 7.5 A, 125 °C - low conduction loss critical for >90 % efficiency in 12 V output rails |
| IFSM | 150 A @ 8.3 ms - withstands startup surges and load-dump transients in automotive-grade power supplies |
| RθJC | 3.0 °C/W - enables thermal design with minimal heatsink mass when mounted to chassis via cathode tab |
| IR @ 125 °C | 50 mA @ 60 V - higher leakage than silicon diodes but acceptable for low-voltage, high-frequency rectification |
| TJ max. | 150 °C - extended junction rating supports operation in enclosed industrial enclosures without forced air |
Pinout & Package
TO-220AC package with isolated mounting tab (pin 2 = cathode), lead-free matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, rated for 275 °C solder bath (10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction; connects to transformer secondary or switch node |
| Pin 2 | Cathode / Mounting Tab | Output terminal and thermally conductive mounting surface; electrically tied to cathode, requires isolation washer if heatsink is grounded |
Key Features
| Feature | Design Value |
|---|---|
| Guardring overvoltage protection | Prevents premature edge breakdown at VRRM, improving reliability in unclamped inductive switching |
| Low forward voltage drop | 0.65 V @ 7.5 A, 125 °C reduces conduction loss by ~30 % vs. comparable Si diodes in same package |
| High surge current capability | 150 A IFSM supports robustness against line transients and hot-plug events |
| High-frequency operation | No reverse recovery charge (Qrr ≈ 0) eliminates switching losses in >100 kHz topologies |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker test; suitable for commercial and industrial reflow assembly |
Applications
| DC/DC Converter Output Rectification | Polarity Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS745E | Same 45 V VRRM, 7.5 A IF(AV), but TO-220AC package with 0.72 V VF @ 7.5 A/125 °C | Higher forward drop increases conduction loss in high-duty-cycle applications | Select when lower cost outweighs 70 mV VF penalty and 45 V rating suffices |
| ON Semi MBR760G | Identical 60 V/7.5 A ratings, same TO-220AC package, but 0.68 V VF @ 7.5 A/125 °C and 120 A IFSM | Slightly lower surge rating may require derating in high-transient environments | Choose for second-source supply continuity where 3 mV VF difference is acceptable |
Compared with STPS745E and MBR760G, the MBRB760HE3_B/I delivers the lowest verified VF (0.65 V) at elevated temperature among TO-220AC 60 V Schottkys, directly reducing thermal load in space-constrained 12 V DC/DC designs.

FAQ
What is the maximum junction temperature rating for the MBRB760HE3_B/I?
The MBRB760HE3_B/I has a maximum junction temperature (TJ) of +150 °C, allowing operation in high-ambient environments such as enclosed industrial power supplies or automotive under-hood applications. This rating is validated per the Vishay datasheet Document Number 88680 and supports derating curves up to that limit without degradation in forward voltage or leakage performance.
Is the MBRB760HE3_B/I RoHS-compliant and lead-free?
Yes, the MBRB760HE3_B/I carries the E3 suffix indicating RoHS-compliance and lead-free construction. Its matte tin-plated leads meet J-STD-002 solderability standards and JESD 201 Class 1A whisker testing requirements, making it suitable for modern reflow and wave soldering processes in commercial and industrial manufacturing.
Does the MBRB760HE3_B/I have a guardring, and what function does it serve?
Yes, the MBRB760HE3_B/I incorporates a guardring structure to suppress edge breakdown under transient overvoltage conditions. This feature enhances reliability in unclamped inductive switching applications-such as freewheeling paths-by preventing localized avalanche at the die periphery and maintaining stable VRRM performance over lifetime.
What is the thermal resistance from junction to case (RθJC) for the MBRB760HE3_B/I?
The MBRB760HE3_B/I has a typical thermal resistance from junction to case (RθJC) of 3.0 °C/W, measured with the cathode tab (pin 2) mounted to an infinite heatsink. This value enables accurate thermal modeling for heatsink sizing in 7.5 A continuous applications and is specified in the Vishay datasheet under Thermal Characteristics.
Can the MBRB760HE3_B/I be used as a direct replacement for the MBR760?
Yes, the MBRB760HE3_B/I is a functionally identical and pin-compatible variant of the MBR760, sharing the same TO-220AC package, electrical specifications (60 V VRRM, 7.5 A IF(AV), 0.65 V VF), and thermal characteristics. The "B" and "HE3_B/I" suffixes denote packaging and tape-and-reel configuration variants-not functional differences-making MBRB760HE3_B/I a valid drop-in replacement.
