Taiwan Semiconductor Corporation SRS1060

Overview

SRS1060 from Taiwan Semiconductor is a 10A, 60V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, featuring dual-die construction, 120A surge capability, and 2°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in DC–DC converters and AC–DC adapters where low forward voltage and fast switching are critical.

For engineers reviewing the SRS1060 datasheet, SRS1060 pinout, SRS1060 application, or SRS1060 equivalent, key selection criteria include its 0.70V typical forward voltage at 5A/25°C, 10mA reverse leakage at 125°C, 60V repetitive peak reverse voltage, and compatibility with automated placement and J-STD-002 soldering standards.

Technical Context

The SRS1060 integrates two independent Schottky die in a single TO-263AB thermally optimized package, enabling dual-channel or parallel rectification without external paralleling. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet JESD 201 Class 2 whisker resistance requirements.

Designed for operation up to 150°C junction temperature, the device delivers stable performance under high ambient conditions typical in compact power supplies. Its 2°C/W R_θJC supports direct heatsinking to PCB copper planes or external metal slugs, reducing thermal derating in high-power density designs.

Key Specifications

Pinout & Package

TO-263AB (D2PAK) package with three terminals: Anode 1, Cathode (common), Anode 2. The cathode tab is electrically connected to the exposed metal pad on the underside, serving as both thermal path and circuit return node.

Compared with VS-10BQ060-M3 and SB1060, the SRS1060 uniquely offers dual-anode isolation in a single package plus 150°C junction rating-making it the only option among the three suitable for dual-rail, high-temperature industrial power conversion without layout duplication or thermal compromise.

Availability

SRS1060 is available at Aetrix Electronics and suitable for switching mode power supplies, DC–DC converters, and AC–DC adapters requiring stable component supply, high surge robustness, and extended temperature operation.

Supply support for SRS1060 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 semiconductor manufacturer headquartered in Hsinchu, Taiwan, specializing in rectifiers, TVS diodes, MOSFETs, and ICs since 1979.

The SRS1020–SRS10150 series was designed specifically for high-efficiency, high-reliability surface-mount rectification in space-constrained power supplies-emphasizing thermal performance, surge resilience, and automated assembly compatibility.

FAQ

What is the maximum junction temperature rating for the SRS1060?

The SRS1060 has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version N2103). This allows uninterrupted operation in sealed industrial enclosures or high-ambient environments where traditional 125°C-rated Schottkys would require derating. The SRS1060 maintains specified electrical parameters up to this limit when thermal design meets R_θJC = 2°C/W.

Does the SRS1060 support automated pick-and-place assembly?

Yes, the SRS1060 is explicitly qualified for automated placement per manufacturer documentation. Its TO-263AB (D2PAK) package features matte tin-plated leads compliant with J-STD-002 solderability standards, and its moisture sensitivity level is rated Level 1 per J-STD-020-eliminating bake requirements prior to reflow. The SRS1060's standardized footprint and marking diagram ensure compatibility with high-speed SMT lines.

How does the dual-die structure of the SRS1060 benefit circuit design?

The SRS1060 integrates two electrically isolated Schottky dies sharing a common cathode, enabling independent anode routing for dual-output or interleaved rectification without adding components. This reduces PCB area by ~40% versus two discrete TO-263AB diodes and eliminates mismatch-induced timing skew. In the SRS1060, each anode handles up to 10A continuously, supporting phase-split topologies in high-density DC–DC converters.

What is the typical forward voltage of the SRS1060 at operating conditions?

The SRS1060 exhibits a typical forward voltage (V_F) of 0.70 V at 5A and 25°C, as confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet (Version N2103). At 10A and 125°C, V_F rises to approximately 0.82 V. This value directly determines conduction loss: at 10A, the SRS1060 dissipates ~8.2 W, making thermal management via the cathode tab essential for sustained operation.

Is the SRS1060 halogen-free and RoHS compliant?

Yes, the SRS1060 is both halogen-free per IEC 61249-2-21 and RoHS compliant, as stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Version N2103). The molding compound contains no brominated or chlorinated flame retardants, and all homogeneous materials meet EU Directive 2011/65/EU restrictions on lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. This ensures global regulatory acceptance for consumer, industrial, and medical-adjacent applications.
