Taiwan Semiconductor Corporation MBR760

Overview

MBR760 from Taiwan Semiconductor is a 7.5A, 60V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.75V at 7.5A, 25°C), 150A surge capability, and AEC-Q101 qualification option. It serves as a high-efficiency output rectifier in DC/DC converters and SMPS where low conduction loss and thermal robustness are critical.

For engineers reviewing the MBR760 datasheet, MBR760 pinout, MBR760 application, or MBR760 equivalent, key selection criteria include its 60V V_RRM, 0.75V forward drop at rated current, 150A I_FSM, junction-to-case thermal resistance of 5°C/W, and TO-220AC mechanical compatibility with standard heatsink mounting.

Technical Context

The MBR760 operates as a single-die, unidirectional Schottky rectifier optimized for high-frequency switching applications. Its 60V repetitive peak reverse voltage and 10,000 V/µs dV/dt rating support stable operation in fast-switching topologies with steep voltage transients.

Thermally, it delivers 15°C/W junction-to-ambient resistance under free-air conditions and 5°C/W junction-to-case resistance, enabling effective heat transfer to external heatsinks. The device is rated for continuous operation from –55°C to +150°C junction temperature.

FAQ

What is the maximum junction temperature rating for the MBR760?

The MBR760 has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as automotive under-hood locations or enclosed industrial power supplies. Derating curves in the datasheet define allowable current versus case temperature, and thermal design must ensure junction temperature remains below this limit under worst-case load and ambient conditions. The MBR760's 5°C/W R_θJC supports effective heatsinking to maintain safe T_J.

Is the MBR760 pin-compatible with other devices in the MBR7xx family?

Yes, all MBR7xx devices - including MBR735, MBR745, MBR750, MBR760, MBR790, MBR7100, and MBR7150 - share identical TO-220AC packaging and pinout: anode (lead 1), cathode (lead 2), and electrically connected case/tab (lead 3). This enables direct voltage-rating substitution within the same board layout, provided thermal and electrical margins (e.g., V_RRM, V_F, I_FSM) are validated for the target application. No PCB changes are required for voltage upgrades or downgrades across the family.

Does the MBR760 have automotive qualification?

The base MBR760 is not AEC-Q101 qualified, but its variant MBR760H is explicitly qualified per AEC-Q101 Rev D for automotive applications. The "H" suffix denotes qualification including stress tests such as HTGB, HTRB, temperature cycling, and ESD. Designers requiring automotive-grade reliability must specify MBR760H - which maintains identical electrical and thermal specifications as MBR760 but adds full qualification documentation and lot-level traceability per automotive requirements.

What is the forward voltage specification for the MBR760 at elevated temperature?

At 7.5A and TJ = 125°C, the MBR760 exhibits a maximum forward voltage (V_F) of 0.65V, per the Electrical Specifications table. This represents a reduction from the 25°C value (0.75V max), reflecting the negative temperature coefficient typical of Schottky diodes. This behavior improves thermal stability in high-temperature operation, as lower V_F reduces self-heating and mitigates thermal runaway risk under sustained load.

How does the guard ring feature improve reliability in the MBR760?

The guard ring in the MBR760 is a diffusion-based structural element surrounding the active junction that controls electric field distribution at the die edge. It prevents premature avalanche breakdown during transient overvoltage events - such as line surges or inductive kickback - thereby increasing the device's ruggedness without requiring external protection components. This feature directly enhances long-term reliability in unregulated or noisy power environments like industrial motor drives or automotive battery systems.
