Product details
Overview
SR4060PT from Taiwan Semiconductor is a 40A, 60V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.70 V forward voltage at 20 A and 25°C, 400 A surge capability, and dual-die construction for high-efficiency DC/DC conversion in automotive and industrial power supplies.
For engineers reviewing the SR4060PT datasheet, SR4060PT pinout, SR4060PT application, or SR4060PT equivalent, key selection criteria include repetitive peak reverse voltage (60 V), junction-to-case thermal resistance (1.2 °C/W), TJ max rating (150°C), reverse leakage (20 mA at 100°C), and UL recognition (E-326243).
Technical Context
The SR4060PT uses dual Schottky die architecture in a single TO-247AD package to deliver parallel conduction paths, enabling 40 A continuous forward current with low conduction loss. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.
Thermally, it achieves 1.2 °C/W junction-to-case resistance, supporting high-power density designs. The device operates across –55°C to +150°C junction temperature range and is rated for 8.3 ms half-sine surge current up to 400 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines usable input voltage headroom in buck or flyback secondary-side rectification |
| IF | 40 A - Continuous forward current rating at case temperature ≤ 125°C; determines minimum heatsink sizing for steady-state operation |
| IFSM | 400 A - Non-repetitive surge current (8.3 ms); supports inrush and transient overload tolerance in SMPS outputs |
| VF | 0.70 V @ 20 A, 25°C - Low forward drop reduces conduction loss and improves system efficiency vs. silicon diodes |
| RθJC | 1.2 °C/W - Thermal resistance from junction to case; enables precise thermal modeling when mounted to heatsink |
| TJ max | +150°C - Maximum allowable junction temperature; permits operation in under-hood automotive environments |
| IR | 20 mA @ 60 V, 100°C - Reverse leakage at elevated temperature; impacts standby power in high-temperature DC/DC converters |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal through-hole package with isolated mounting tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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; VF = 0.69 V @ 20 A but no AEC-Q101 qualification | Not qualified for automotive under-hood use; suitable for industrial/commercial SMPS only | Select when AEC-Q101 is not required and UL recognition is secondary to cost |
| ON Semiconductor MBR4060CT | 60 V VRRM, 40 A IF, TO-220AB package; VF = 0.72 V @ 20 A; no UL file or halogen-free claim | Lower thermal performance (RθJC ≈ 2.5 °C/W); limited to lower-power adapters and non-automotive applications | Select when board space constraints favor TO-220 and thermal budget allows higher RθJC |
Compared with VS-40CPH06-M3 and MBR4060CT, the SR4060PT uniquely combines AEC-Q101 qualification, UL recognition, halogen-free compliance, and 1.2 °C/W thermal resistance-making it the only option qualified for thermally demanding, safety-critical automotive and industrial power systems requiring long-term reliability.

FAQ
What is the maximum junction temperature rating for the SR4060PT?
The SR4060PT 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. Derating curves in the official datasheet specify that continuous forward current drops to approximately 28 A at 125°C case temperature. The SR4060PT must be thermally managed using its TO-247AD mounting tab to maintain junction temperature within this limit.
Is the SR4060PT pin-compatible with other parts in the SR40xxPT series?
Yes, all SR40xxPT devices-including SR4060PT-share identical TO-247AD (TO-3P) mechanical footprint, pinout, and terminal configuration. The only differences are VRRM (20 V to 100 V) and associated electrical parameters like forward voltage and reverse leakage. This enables drop-in voltage-scaling flexibility during design validation or BOM optimization without PCB layout changes.
Does the SR4060PT have UL recognition, and what is the file number?
Yes, the SR4060PT is UL Recognized under File # E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for end-product safety certification. This applies to the entire SR40xxPT family and covers flammability (UL 94V-0), terminal solderability (J-STD-002), and whisker resistance (JESD 201 Class 2). The recognition is valid for both standard and AEC-Q101-qualified versions (SR4060PTH).
What is the forward voltage specification for the SR4060PT at 40 A?
The SR4060PT datasheet specifies forward voltage (VF) at 20 A (0.70 V typical, 25°C), not 40 A. At 40 A, VF rises due to resistive and thermal effects; typical values exceed 0.85 V at 25°C and increase further at elevated temperatures. Designers should consult Figure 4 (Typical Forward Characteristics) in the official SR4020PT–SR40100PT datasheet to interpolate VF at 40 A and target junction temperature.
How does the guard ring feature improve reliability in the SR4060PT?
The guard ring in the SR4060PT is a diffusion-based edge termination structure that distributes electric field stress away from the active junction periphery. This prevents premature avalanche breakdown during voltage transients-such as load dump or inductive switching spikes in automotive 12 V systems-and extends device lifetime under repetitive overvoltage conditions. It eliminates the need for external clamping circuits in many 60 V-class applications.
