Taiwan Semiconductor Corporation SRS10150

Overview

SRS10150 from Taiwan Semiconductor is a 10A, 150V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, featuring dual-die construction, 1.00V forward voltage at 5A/25°C, 100µA reverse leakage at rated VR and 120A surge capability - deployed in high-efficiency DC-DC converters and industrial SMPS.

For engineers reviewing the SRS10150 datasheet, SRS10150 pinout, SRS10150 application, or SRS10150 equivalent, key selection factors include its 150V V_RRM, 125–150°C junction temperature range, TO-263AB thermal resistance of 2°C/W, and low-leakage performance at elevated temperatures.

Technical Context

The SRS10150 implements a dual-die Schottky structure optimized for high-voltage switching rectification, with guard ring overvoltage protection and JESD201 Class 2 whisker resistance. Its 150V V_RRM rating enables use in 48V+ bus systems where higher reverse standoff is required versus lower-voltage variants like SRS1060.

Thermal design leverages the TO-263AB package's 2°C/W junction-to-case resistance and 1.37g mass, supporting continuous 10A conduction up to 125°C ambient when properly heatsinked - validated by derating curves showing 0A at 150°C case temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Compared with VS-10BQ150P-M3 and SB10150, the SRS10150 offers the lowest reverse leakage (100µA) among 150V/10A Schottkys, making it optimal for energy-efficient adapters and always-on industrial controllers - though its 1.00V V_F sits between the two alternatives.

Availability

SRS10150 is available at Aetrix Electronics and suitable for server power supplies, industrial DC-DC converters, and telecom rectifier modules requiring stable component supply, long-lifecycle assurance, and RoHS/halogen-free compliance.

Supply support for SRS10150 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and power discrete manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, computing, and telecom markets since 1979.

The SRS series targets high-efficiency switching rectification, with the SRS10150 specifically engineered for 150V-class SMPS outputs where low leakage and robust surge handling are prioritized over minimal forward voltage.

FAQ

What is the maximum junction temperature rating for the SRS10150?

The SRS10150 has a maximum junction temperature (T_J) rating of +150°C, confirmed in the Absolute Maximum Ratings table. This allows operation in high-ambient environments such as sealed industrial enclosures or under forced-air cooling in telecom power shelves. The device is rated for continuous 10A conduction up to 125°C case temperature, with derating applied beyond that point per the published forward current derating curve.

Does the SRS10150 have a guard ring structure, and what benefit does it provide?

Yes, the SRS10150 incorporates a guard ring structure explicitly listed in its FEATURES section. This design enhances edge termination robustness, improving resistance to transient overvoltage events such as line surges or switching-induced dv/dt stress - reducing the need for external snubber networks in high-reliability applications like EV charging auxiliary supplies.

What is the reverse leakage current specification for the SRS10150 at 150V and 25°C?

The SRS10150 specifies a maximum reverse leakage current (I_R) of 100 µA at rated V_R = 150V and T_J = 25°C, per the Electrical Specifications table. This value is significantly lower than comparable 150V Schottkys (e.g., SB10150 at 200 µA), making the SRS10150 especially suitable for low-standby-power applications such as always-on industrial controllers.

Is the SRS10150 RoHS and halogen-free compliant?

Yes, the SRS10150 is RoHS compliant and halogen-free according to IEC 61249-2-21, as stated in the FEATURES section. Its molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 - confirming full compliance with environmental and assembly standards for modern industrial and telecom equipment.

What is the thermal resistance from junction to case (R_θJC) for the SRS10150?

The SRS10150 has a typical junction-to-case thermal resistance (R_θJC) of 2°C/W, as specified in the Thermal Performance section. This value applies to the TO-263AB (D2PAK) package with proper mounting to a copper heatsink area, enabling efficient thermal transfer in high-power-density designs such as server PSUs and industrial DC-DC converters.
