Product details
Overview
SR16150PT from Taiwan Semiconductor is a 16A, 150V Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 1.00V forward voltage at 8A and 100µA reverse current at rated VR and 25°C. It delivers high surge capability (200A IFSM), junction-to-case thermal resistance of 3°C/W, and operates up to 150°C TJ. Used in high-efficiency SMPS and DC-DC converters where low conduction loss and robust transient handling are critical.
For engineers reviewing the SR16150PT datasheet, SR16150PT pinout, SR16150PT application, or SR16150PT equivalent, key selection criteria include its 150V VRRM rating, dual-die configuration, AEC-Q101 qualification availability (SR16150PTH), TO-247AD mechanical compatibility, and thermal performance validated per JESD201 Class 2 whisker testing.
Technical Context
This device is a single-phase, dual-die Schottky rectifier optimized for high-current, high-voltage switching applications. Its architecture enables low VF at elevated currents while maintaining tight thermal resistance (RθJC = 3°C/W) and high IFSM (200A) under 8.3ms half-sine surge conditions.
The SR16150PT operates with a maximum junction temperature of +150°C and exhibits 5mA reverse leakage at 125°C - a critical parameter for thermal design in compact power supplies. Its guard ring structure provides overvoltage protection, and matte tin-plated leads ensure solderability per J-STD-002.

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-16EWH15 | 16A, 150V, TO-247AC package; VF = 0.92V @ 8A; RθJC = 3.5°C/W | Slightly lower VF but higher thermal resistance; no AEC-Q101 variant listed | Preferred where absolute lowest conduction loss is prioritized over thermal coupling efficiency |
| ON Semiconductor MUR1615CT | 16A, 150V, TO-220AB package; fast recovery (not Schottky); VF ≈ 1.25V @ 8A | Higher VF increases conduction loss; TO-220AB has inferior thermal performance (RθJC ≈ 5.0°C/W) | Only suitable if Schottky characteristics are not required and board space limits TO-247 adoption |
Compared with VS-16EWH15 and MUR1615CT, the SR16150PT offers superior thermal coupling (3°C/W), AEC-Q101 qualification path (via SR16150PTH), and consistent Schottky behavior across temperature - making it optimal for automotive-grade or thermally aggressive industrial designs.

FAQ
What is the maximum junction temperature rating for SR16150PT?
The SR16150PT has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official TSC datasheet Version J2103. This allows operation in thermally demanding environments such as enclosed power adapters or industrial motor drives. The SR16150PT maintains specified electrical parameters up to this limit when thermal design respects the 3°C/W RθJC value.
Is SR16150PT pin-compatible with other parts in the SR16xxPT family?
Yes, all SR16xxPT variants - including SR1620PT through SR16150PT - share identical TO-247AD (TO-3P) packaging and 3-pin pinout (Anode, Cathode, Cathode-connected tab). The SR16150PT uses the same mechanical footprint and mounting torque specification (1.13 N·m max), enabling direct PCB layout reuse across voltage grades.
Does SR16150PT meet AEC-Q101 reliability standards?
The SR16150PT itself is not AEC-Q101 qualified, but its qualified variant SR16150PTH is explicitly listed in TSC documentation as AEC-Q101 compliant. The "H" suffix denotes qualification per AEC-Q101 Rev D, including stress tests for temperature cycling, humidity, and high-temperature operating life - critical for automotive infotainment and ADAS power supplies.
What is the forward voltage of SR16150PT at 16A and 125°C?
The SR16150PT datasheet specifies VF = 1.00V at IF = 8A and TJ = 25°C. At 16A and 125°C, VF increases due to temperature coefficient and current scaling; typical curves (Fig.4) show ~1.15–1.20V under those conditions. Designers should use the derating curve (Fig.1) and thermal model to confirm actual VF in system-level thermal environments.
How does SR16150PT's reverse leakage compare to lower-voltage variants in the same family?
At 25°C and rated VR, SR16150PT exhibits 100µA IR - lower than SR1620PT–SR1660PT (500µA) but aligned with SR1690PT–SR16100PT (100µA). This reflects optimized doping and guard ring design for higher-voltage Schottky structures. At 125°C, SR16150PT shows 5mA IR, matching SR1690PT–SR16100PT and significantly better than lower-voltage parts that degrade faster with temperature.
