Product details
Overview
SR3060PT from Taiwan Semiconductor is a 30A, 60V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.70 V forward voltage at 15 A and 25°C, 300 A surge capability, 1.5 °C/W junction-to-case thermal resistance, and guard ring overvoltage protection - used in high-efficiency DC/DC converters and automotive-grade power supplies.
For engineers reviewing the SR3060PT datasheet, SR3060PT pinout, SR3060PT application, or SR3060PT equivalent, key selection criteria include repetitive peak reverse voltage (60 V), forward current rating (30 A), thermal performance (RθJC = 1.5 °C/W), AEC-Q101 qualification status, and TO-247AD mechanical compatibility for high-power thermal management.
Technical Context
The SR3060PT is a dual-die Schottky rectifier optimized for low conduction loss in high-frequency switching applications. Its 60 V VRRM, 30 A average forward current, and 300 A non-repetitive surge rating support robust operation in SMPS and automotive DC/DC stages where fast recovery and minimal reverse recovery charge are critical.
Thermal design is enabled by its TO-247AD package with 1.5 °C/W RθJC, matte tin-plated leads compliant with J-STD-002, and UL 94V-0 molding compound. Junction temperature range spans –55°C to +150°C, supporting extended-life operation under sustained load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in DC/DC flyback or buck output rectification. |
| IF | 30 A - Continuous average forward current at case temperature ≤ 125°C; determines steady-state power handling capacity. |
| IFSM | 300 A - Peak non-repetitive surge current (8.3 ms half-sine); enables tolerance of inrush and transient overload events. |
| VF | 0.70 V @ 15 A, 25°C - Low forward drop reduces conduction loss and improves system efficiency in high-current paths. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; allows accurate heatsink sizing for thermal management in TO-247AD mounting. |
| TJ max | +150°C - Maximum junction temperature rating; supports extended reliability in under-hood or enclosed industrial environments. |
| IR | 15 mA @ 60 V, 100°C - Reverse leakage current at elevated temperature; impacts standby power and thermal runaway risk in parallel configurations. |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal through-hole package with isolated metal 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 |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to source-side of switching node; requires low-inductance layout to minimize voltage spikes during commutation. |
| Cathode (Lead 2) | Output current exit point | Common cathode connection for dual-die configuration; electrically tied to metal tab for enhanced thermal conduction. |
| Metal Tab (Cathode) | Thermal & electrical cathode node | Provides primary heat path to heatsink; must be electrically isolated unless system-level cathode reference permits direct mounting. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics per stress test requirements including HTOL, TC, HTRB, and UHAST - enables use in engine control, ADAS, and infotainment power rails. |
| Guard ring structure | Integrated edge termination enhances voltage standoff margin and prevents premature avalanche breakdown under transient overvoltage conditions. |
| High surge current capability | 300 A IFSM supports reliable operation during cold-crank or load-dump transients without bond-wire fusing. |
| Low forward voltage | 0.70 V VF at 15 A reduces conduction loss by ~25% vs. comparable 60 V Si diodes, directly improving converter efficiency at 12–48 V input ranges. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - required for automotive OEM and industrial equipment environmental compliance. |

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-30CPH06-M3 | Same 60 V VRRM, 30 A IF, TO-247AC package; VF = 0.69 V @ 15 A but no AEC-Q101 qualification. | Not approved for automotive use; suitable for industrial/commercial SMPS only. | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs. |
| ON Semiconductor MUR3060CT | 60 V, 30 A, TO-247AC; ultrafast recovery silicon diode (trr = 60 ns), VF = 1.15 V - higher conduction loss, no Schottky advantages. | Used where reverse recovery noise must be minimized despite efficiency penalty; not a Schottky replacement. | Select only if EMI constraints prohibit Schottky reverse leakage or require controlled soft recovery. |
Compared with VS-30CPH06-M3 and MUR3060CT, the SR3060PT uniquely combines AEC-Q101 qualification, Schottky low-VF performance (0.70 V), and TO-247AD thermal robustness - making it the preferred choice for automotive and high-reliability industrial DC/DC rectification where both efficiency and qualification are mandatory.

FAQ
What is the maximum junction temperature rating for the SR3060PT?
The SR3060PT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official datasheet. This allows operation in high-ambient environments such as automotive under-hood locations or sealed industrial enclosures. The SR3060PT maintains specified electrical performance up to this limit when thermal design respects the 1.5 °C/W RθJC and proper heatsinking is applied. Derating curves confirm usable current capacity down to 0 A at 150°C case temperature.
Is the SR3060PT AEC-Q101 qualified?
Yes, the SR3060PT is AEC-Q101 qualified, as confirmed in the "Features" section and ordering code notes (SR3060PTH denotes AEC-Q101 version). Qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). This makes the SR3060PT suitable for automotive power modules, body control units, and ADAS subsystems where component reliability is mandated.
What is the forward voltage specification for the SR3060PT at rated current?
The SR3060PT exhibits a typical forward voltage (VF) of 0.70 V at 15 A and 25°C, per the Electrical Specifications table. This value is measured under pulse conditions (PW = 0.3 ms) and reflects low conduction loss essential for high-efficiency designs. At higher junction temperatures (e.g., 100°C), VF decreases slightly, while forward current capability is thermally limited per the derating curve - ensuring predictable behavior across operating conditions.
Does the SR3060PT have a guard ring structure, and what is its function?
Yes, the SR3060PT incorporates a guard ring structure, explicitly listed under "Features" in the datasheet. This edge termination design increases the effective breakdown voltage margin and prevents localized electric field concentration at the die periphery. It enhances robustness against transient overvoltage events such as load dump or inductive switching spikes - a critical feature for automotive and industrial power rectification where reliability under electrical stress is paramount.
What packaging and marking information applies to the SR3060PT?
The SR3060PT is supplied in TO-247AD (TO-3P) package with matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on the device body. Marking code is "SR3060PT", followed by green compound indicator (G), date code (YWW), and factory code (F). Packing is 30 units per tube. Mechanical drawings confirm lead spacing, tab dimensions, and mounting torque limit of 1.13 N·m - all documented in the "Package Outline Dimensions" section of the datasheet.
