Taiwan Semiconductor Corporation MBR760H

Overview

MBR760H from Taiwan Semiconductor is a 7.5A, 60V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.75V forward voltage at 7.5A/25°C, 150A surge capability, and guard ring overvoltage protection. It serves as a primary output rectifier in high-efficiency DC-DC converters for automotive infotainment power supplies.

For engineers reviewing the MBR760H datasheet, MBR760H pinout, MBR760H application, or MBR760H equivalent, key selection criteria include its 60V V_RRM, 150°C junction rating, AEC-Q101 qualification status, thermal resistance (R_θJC = 5°C/W), and low VF performance at elevated temperature.

Technical Context

This single-die Schottky rectifier uses platinum-silicide barrier technology to achieve low forward voltage and fast switching with no minority-carrier storage delay. Its guard ring structure enhances ruggedness against transient overvoltage events common in automotive load-dump conditions.

The device operates across -55°C to +150°C junction temperature range and supports 8.3ms half-sine surge currents up to 150A. Thermal design is enabled by validated R_θJA = 15°C/W (free-air) and R_θJC = 5°C/W metrics for heatsink interface planning.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global automotive, industrial, and computing markets since 1979.

The MBR760H belongs to TSC's AEC-Q101-qualified Schottky rectifier product line, engineered specifically for high-reliability 12V/24V/48V automotive power conversion where low VF, surge robustness, and thermal stability are critical.

FAQ

What is the maximum junction temperature rating for MBR760H?

The MBR760H has a maximum junction temperature (T_J) of +150°C, validated per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive environments where ambient temperatures reach 125°C, provided thermal design maintains junction temperature within this limit using the confirmed R_θJC = 5°C/W path. The MBR760H datasheet specifies derating curves starting at 25°C ambient.

Is MBR760H pin-compatible with standard TO-220AC rectifiers?

Yes, the MBR760H uses JEDEC-standard TO-220AC mechanical outline with Anode–Cathode–Tab pinout (Lead 1 = Anode, Lead 2 = Cathode, Tab = isolated thermal pad). It matches footprint and mounting hole positions of industry-standard 7.5A Schottky rectifiers like STPS745, VBSE760, and VS-MBR760, enabling direct PCB replacement without layout changes.

Does MBR760H require a heatsink in 7.5A continuous operation?

Yes, sustained 7.5A conduction requires heatsinking. With R_θJC = 5°C/W and R_θCA dependent on heatsink size, a typical 15°C/W heatsink yields ~105°C junction rise above ambient at full load. For 75°C ambient, this reaches 180°C-exceeding the 150°C limit. A minimum 8°C/W heatsink is recommended for 7.5A continuous use, verified using the MBR760H derating curve in Figure 1.

What does the "H" suffix signify in MBR760H?

The "H" suffix in MBR760H denotes full AEC-Q101 qualification per Rev D test plan, including HTGB, TC, HTRB, uHAST, and ESD testing. Unlike standard MBR760, the MBR760H undergoes additional screening for automotive use, with certified lot traceability, PPAP documentation support, and guaranteed parametric stability across temperature and lifetime. This makes MBR760H suitable for safety-critical vehicle subsystems.

How does MBR760H perform at elevated temperature compared to room temperature?

At 125°C junction temperature, the MBR760H exhibits VF = 0.65V @ 7.5A-only 0.10V higher than its 0.75V rating at 25°C. Reverse leakage rises to 10mA at 125°C (vs. <100µA at 25°C), remaining well within design margins for most 12V systems. These values are measured and published in the MBR760H electrical specifications table, confirming stable performance across the full -55°C to +150°C operating range.
