Product details
Overview
MBR4060PT from Taiwan Semiconductor is a 40A, 60V dual-die Schottky barrier rectifier in TO-247AD package, featuring 0.77V max forward voltage at 20A/25°C, 330A surge capability, and AEC-Q101 qualification option. It serves as a high-efficiency output rectifier in DC-DC converters and SMPS for industrial power supplies.
For engineers reviewing the MBR4060PT datasheet, MBR4060PT pinout, MBR4060PT application, or MBR4060PT equivalent, key selection criteria include VRRM = 60 V, IF = 40 A continuous, RθJC = 1.2 °C/W, low IR ≤ 1000 µA at 25°C, and TO-247AD mechanical compatibility with heatsink mounting.
Technical Context
This dual-die Schottky rectifier uses guard ring structure for overvoltage protection and meets UL 94V-0 flammability rating. Its junction temperature range spans –55°C to +150°C, with dV/dt rating of 10,000 V/µs and JESD201 Class 2 whisker resistance.
Designed for high-frequency switching applications, it delivers low conduction loss (VF ≤ 0.77 V @ 20A/25°C) and high thermal efficiency via low RθJC = 1.2 °C/W. Reverse leakage remains ≤20 mA at 125°C and rated VR, supporting stable operation in thermally demanding environments.

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-40CPH06 | Same 60V VRRM, 40A IF, TO-247AC package; slightly higher VF (0.82 V typ @ 20A) | Identical use in SMPS output stages; lower thermal resistance (1.0 °C/W) but no AEC-Q101 variant | Select when lower RθJC is prioritized and automotive qualification is not required |
| ON Semiconductor MBR4060CT | 60V VRRM, 40A IF, TO-220AB package; single-die, non-isolated tab, higher RθJC (2.5 °C/W) | Suitable for lower-power or cost-sensitive adapters; limited to <25A continuous without heatsink | Select for space-constrained consumer adapters where TO-247 mounting is impractical |
Compared with VS-40CPH06 and MBR4060CT, the MBR4060PT offers superior thermal performance in TO-247AD with isolated tab, AEC-Q101 availability, and tighter VF control-making it optimal for industrial and automotive-grade 40A rectification where reliability and thermal margin are critical.

FAQ
What is the maximum junction temperature rating for the MBR4060PT?
The MBR4060PT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in enclosed industrial power supplies and automotive under-hood environments where ambient temperatures exceed 85°C. Derating curves confirm usable current down to 25A at 125°C case temperature. The MBR4060PT must be mounted to a heatsink meeting thermal impedance targets to sustain this rating.
Does the MBR4060PT have AEC-Q101 qualification?
The base MBR4060PT is not AEC-Q101 qualified; however, the variant MBR4060PTH (with 'H' suffix) is explicitly AEC-Q101 qualified per ordering information. The MBR4060PT shares identical electrical and thermal specifications with the 'H' version except for the qualification testing. For automotive applications requiring AEC-Q101, specify MBR4060PTH-not MBR4060PT-to ensure compliance.
What is the forward voltage specification for the MBR4060PT at full rated current?
The MBR4060PT specifies a maximum forward voltage (VF) of 0.77 V at 20A and 25°C, per electrical specifications table. At 40A and 25°C, the datasheet does not list a guaranteed maximum VF, but typical curves show ~0.85 V. For design margin, engineers should use 0.77 V at 20A or apply derating; the MBR4060PT is not characterized for 40A VF at 25°C in the published data.
How is the TO-247AD package of the MBR4060PT mechanically configured for mounting?
The MBR4060PT uses TO-247AD (also called TO-3P) with three leads and an isolated metal tab. Mounting torque must not exceed 1.13 N·m. The tab is electrically isolated from all leads per JEDEC outline, enabling direct heatsink attachment without insulating hardware. Polarity is marked on the device body, and terminals are matte tin-plated for J-STD-002 solderability. Weight is approximately 6.10 g.
What is the reverse leakage current of the MBR4060PT at elevated temperature?
At rated 60V reverse voltage and 125°C junction temperature, the MBR4060PT exhibits a maximum reverse leakage current (IR) of 20 mA, per electrical specifications. This value is critical for standby power budgeting in always-on systems. At 25°C and 60V, leakage is capped at 1000 µA. The MBR4060PT's leakage remains stable across its full –55°C to +150°C operating range, supporting consistent performance in wide-temperature deployments.
