Product details
Overview
SR4060PT from Taiwan Semiconductor is a 40A, 60V Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring dual-die construction, 400A surge capability, 1.2°C/W junction-to-case thermal resistance, and 0.70V forward voltage at 20A/25°C. It serves as a high-efficiency output rectifier in automotive-grade SMPS and DC-DC converters.
For engineers reviewing the SR4060PT datasheet, SR4060PT pinout, SR4060PT application, or SR4060PT equivalent, key selection criteria include its AEC-Q101 qualification option (SR4060PTH), 60V VRRM, 20mA reverse leakage at 100°C, -55°C to +150°C operating junction range, and TO-247AD mechanical compatibility with high-power thermal management requirements.
Technical Context
This device implements a dual-die Schottky architecture optimized for low conduction loss in high-current switching power supplies. Its guard ring structure provides overvoltage protection, while the matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance standards.
The SR4060PT operates across -55°C to +150°C junction temperature range with 1.2°C/W RθJC, enabling stable performance under sustained 40A DC load when mounted with ≤1.13 N·m torque on heatsinks. Reverse leakage remains ≤20mA at 100°C and rated 60V VR.
Key Specifications

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; 0.72V VF @ 20A, higher 1.5°C/W RθJC | Lacks AEC-Q101 option; not UL Recognized | Prefer SR4060PT where automotive qualification or UL safety listing is required |
| ON Semiconductor MUR460 | 600V PIV, 4A IF, DO-201AD package; fast recovery silicon, not Schottky | Lower current rating, higher VF (~1.7V), unsuitable for high-efficiency 40A designs | Only consider for low-cost, low-power legacy replacements-not a functional alternative for SR4060PT's 40A/60V role |
Compared with VS-40CPH06, SR4060PT offers lower thermal resistance and automotive qualification; compared with MUR460, it delivers 10× higher current capacity and Schottky-level efficiency-making it irreplaceable in modern high-power, high-efficiency rectification.

FAQ
What is the maximum junction temperature rating for SR4060PT?
The SR4060PT has a maximum junction temperature (TJ) of +150°C, with operational range from -55°C to +150°C. This rating is validated per absolute maximum ratings table and supports use in under-hood automotive environments and thermally constrained industrial enclosures where ambient temperatures exceed 85°C.
Is SR4060PT pin-compatible with other devices in the SR40xxPT family?
Yes, all SR40xxPT devices-including SR4020PT, SR4030PT, SR4040PT, SR4050PT, SR4060PT, SR4090PT, and SR40100PT-share identical TO-247AD (TO-3P) package dimensions, pinout, and mechanical mounting. Only VRRM and associated electrical parameters differ across the family.
Does SR4060PT have AEC-Q101 qualification?
The SR4060PT itself is not AEC-Q101 qualified; however, the SR4060PTH variant-identical in all electrical and mechanical specifications except for qualification status-is fully AEC-Q101 certified. Customers requiring automotive qualification must specify SR4060PTH in ordering code.
What is the forward voltage specification for SR4060PT at elevated temperature?
Per electrical specifications, SR4060PT exhibits typical forward voltage of 0.70V at 20A and 25°C. At 100°C junction temperature, VF decreases slightly due to Schottky physics, but datasheet does not publish a specific value-designers should use 0.70V as worst-case for room-temperature thermal margining.
How is polarity marked on the SR4060PT package?
Polarity is marked on the top surface of the SR4060PT TO-247AD package per the official marking diagram: cathode is indicated by a band or "K" symbol adjacent to the cathode lead; anodes are unmarked and identified by position relative to the cathode in the standard TO-247AD pinout orientation.
