Product details
Overview
SR20150 from Taiwan Semiconductor is a 20A, 150V Schottky barrier rectifier in TO-220AB package, featuring dual-die construction, 1.00V forward voltage at 10A/25°C, 100µA reverse leakage at rated VR/25°C, and 200A surge capability-designed for high-efficiency DC/DC converters in automotive power supplies.
For engineers reviewing the SR20150 datasheet, SR20150 pinout, SR20150 application, or SR20150 equivalent, key selection criteria include its 150V VRRM rating, 125–150°C junction temperature range, AEC-Q101 qualification option (SR20150H), thermal resistance of 1°C/W, and TO-220AB mechanical compatibility with standard heatsink mounting.
Technical Context
The SR20150 implements a dual-die Schottky structure optimized for low conduction loss at high blocking voltage, enabling operation up to 150V reverse bias while maintaining fast switching with no minority-carrier recovery. Its guard ring design enhances ruggedness against transient overvoltage events.
Thermal performance is defined by a junction-to-case resistance of 1°C/W and a maximum junction temperature of 150°C under continuous operation, supporting stable performance in compact, convection-cooled SMPS layouts where thermal management is constrained.

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-20CPH15 | Same 20A/150V rating, TO-247AC package, VF = 0.92V @ 10A, RθJC = 0.9°C/W | Higher thermal performance but larger footprint; requires PCB rework for TO-220AB-to-TO-247AC transition | Preferred when thermal headroom is critical and board space allows TO-247AC mounting |
| ON Semiconductor MUR20150CT | Ultrafast recovery diode (not Schottky), VF = 1.75V @ 10A, TJ max = 175°C, higher switching loss | Used where high-temperature operation (>150°C) is required, but sacrifices efficiency in high-frequency designs | Select only if junction temperature exceeds 150°C or if reverse recovery robustness outweighs conduction loss concerns |
Compared with VS-20CPH15 and MUR20150CT, the SR20150 delivers optimal balance of low VF (1.00V), industry-standard TO-220AB fit, and AEC-Q101 availability-making it the preferred choice for cost-sensitive, space-constrained 150V Schottky rectification where thermal design targets ≤150°C junction.

FAQ
What is the maximum junction temperature rating for SR20150?
The SR20150 has a maximum junction temperature (TJ max) of 150°C under continuous operation. This rating applies to the standard version and defines the upper thermal limit for reliable long-term operation. Derating curves in the datasheet specify allowable forward current reduction above 75°C case temperature to maintain this junction limit.
Is SR20150 available in an AEC-Q101 qualified version?
Yes, the SR20150H is the AEC-Q101 qualified variant of the SR20150. It undergoes additional stress testing per the AEC-Q101 standard for discrete semiconductors and is marked with the "H" suffix in the ordering code. The SR20150H shares identical electrical and thermal specifications with the base SR20150.
What is the forward voltage drop of SR20150 at rated current?
The SR20150 exhibits a typical forward voltage (VF) of 1.00 V at 10 A and 25°C junction temperature. This value is measured per diode under pulsed conditions (PW = 0.3 ms). At higher temperatures or currents, VF increases slightly-e.g., ~1.15 V at 10 A and 100°C.
Does SR20150 have a common-cathode configuration?
Yes, the SR20150 uses a common-cathode dual-die configuration in TO-220AB package. The cathode terminals of both Schottky dies are internally bonded to the metal tab and Pin 2, while Anode 1 and Anode 2 are brought out to Pins 1 and 3 respectively-enabling independent anode control in two-phase or interleaved topologies.
What is the reverse leakage current specification for SR20150 at full rated voltage?
The SR20150 specifies a maximum reverse leakage current (IR) of 100 µA at 150 V reverse voltage and 25°C junction temperature. At elevated temperatures, IR rises: it reaches 5 mA at 125°C and 150 V, which remains within acceptable limits for most high-efficiency power supply standby modes.
