Product details
Overview
SR4060PTH from Taiwan Semiconductor is a 40A, 60V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.70V forward voltage at 20A/25°C, 400A surge capability, and 1.2°C/W junction-to-case thermal resistance for high-efficiency power conversion in automotive and industrial SMPS.
For engineers reviewing the SR4060PTH datasheet, SR4060PTH pinout, SR4060PTH application, or SR4060PTH equivalent, key selection criteria include repetitive peak reverse voltage (60 V), forward current rating (40 A), thermal performance (RθJC = 1.2°C/W), AEC-Q101 qualification status, and TO-247AD mechanical compatibility.
Technical Context
This dual-die Schottky rectifier operates with low conduction loss due to its 0.70 V typical forward voltage at 20 A and 25°C, enabling high-efficiency DC–DC conversion. Its 60 V VRRM rating supports mid-voltage industrial and automotive power rails, while the guard ring structure provides overvoltage protection.
The device sustains 400 A non-repetitive surge current (8.3 ms half-sine) and operates up to 150°C junction temperature, with thermal resistance of 1.2°C/W ensuring effective heat transfer to heatsinks in high-power adapters and converters.

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-M3 | Same 60 V VRRM, 40 A IF, TO-247AC package; 0.72 V VF @ 20 A; not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial but not automotive OBC or ADAS modules | Select when AEC-Q101 is not required and Vishay supply chain preference applies |
| ON Semiconductor MBR4060CT | 60 V VRRM, 40 A IF, TO-220AB package; dual common-cathode; 0.75 V VF; no AEC-Q101 or UL recognition | Smaller TO-220 package limits thermal performance; unsuitable for >25 A continuous without forced airflow | Choose only for cost-sensitive, lower-power applications where thermal headroom exceeds 15°C |
Compared with VS-40CPH06-M3 and MBR4060CT, SR4060PTH delivers superior thermal management (1.2°C/W vs. ≥2.0°C/W), automotive qualification, and UL recognition-making it the preferred choice for thermally constrained, safety-critical, or automotive-grade designs requiring long-term reliability.

FAQ
What is the maximum junction temperature rating for SR4060PTH?
The SR4060PTH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings where thermal management is constrained. The SR4060PTH maintains full 40 A current capability up to 125°C and derates linearly beyond that point, with thermal shutdown not required below 150°C.
Is SR4060PTH pin-compatible with other parts in the SR40xPT family?
Yes, all SR40xPT and SR40xPTH variants-including SR4060PTH-share identical TO-247AD (TO-3P) package dimensions, pinout, and mechanical mounting features. The only differences are VRRM ratings (20 V to 100 V) and corresponding forward voltage and leakage characteristics; PCB layout and heatsink interface remain unchanged across the family.
Does SR4060PTH require a heatsink in 40 A continuous operation?
Yes, SR4060PTH requires a heatsink for 40 A continuous operation. With 0.70 V forward voltage, power dissipation reaches ~28 W at full load. Given its 1.2°C/W RθJC, a heatsink maintaining ≤45°C case temperature is necessary to keep junction temperature below 150°C. Natural convection alone is insufficient; forced-air or bonded aluminum heatsinks are recommended.
What does the "H" suffix in SR4060PTH signify?
The "H" suffix in SR4060PTH indicates AEC-Q101 qualification. This means the device has passed the full suite of automotive reliability tests-including temperature cycling, high-temperature reverse bias (HTRB), and ESD-per AEC-Q101 Rev D. It is not merely compliant with automotive-grade materials; it is fully qualified for use in automotive powertrain and charging systems.
How does SR4060PTH compare to standard silicon rectifiers in SMPS applications?
SR4060PTH replaces standard silicon rectifiers with significantly lower forward voltage (0.70 V vs. 1.1–1.3 V), reducing conduction losses by 35–45% at 20 A. Its zero-recovery characteristic eliminates switching loss and EMI associated with reverse recovery charge, enabling higher-frequency operation and smaller passive components. Unlike silicon, it does not require snubber networks in most topologies.
