Taiwan Semiconductor Corporation SRS2060

Overview

SRS2060 from Taiwan Semiconductor is a 20A, 60V Schottky barrier rectifier in TO-263AB (D2PAK) package, designed for high-efficiency DC/DC conversion and SMPS secondary-side rectification. It features 0.70V forward voltage at 10A/25°C, 200A non-repetitive surge capability, 1.5°C/W junction-to-case thermal resistance, and operates up to +150°C junction temperature.

For engineers reviewing the SRS2060 datasheet, SRS2060 pinout, SRS2060 application, or SRS2060 equivalent, key selection factors include its 60V VRRM rating, dual-die configuration, moisture sensitivity level 1 compliance, JESD201 Class 2 whisker resistance, and suitability for automated SMT placement in high-density power supplies.

Technical Context

The SRS2060 integrates two Schottky die in a single TO-263AB thermally optimized package, enabling parallel conduction paths without external paralleling. Its guard ring structure provides overvoltage protection, while the matte tin-plated leads ensure reliable solderability per J-STD-002.

Rated for continuous 20A forward current and 200A surge (8.3ms half-sine), the device maintains low conduction loss with 0.70V VF at 10A/25°C and exhibits only 10mA reverse leakage at 100°C under rated 60V reverse bias - critical for thermal stability in compact converters.

FAQ

What is the maximum junction temperature rating for the SRS2060?

The SRS2060 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This rating allows uninterrupted operation in sealed enclosures or high-ambient environments without derating, provided thermal design meets RθJC = 1.5°C/W and sufficient PCB copper area is allocated to the cathode tab. The SRS2060 maintains specified electrical parameters up to this limit.

Does the SRS2060 have a dual-die configuration, and how does it affect circuit design?

Yes, the SRS2060 integrates two independent Schottky diodes sharing a common cathode terminal in a single TO-263AB package. This dual-die structure enables current sharing in center-tapped transformer designs or redundant conduction paths without external paralleling. It eliminates mismatch-induced thermal imbalance and reduces PCB footprint versus discrete dual-diode solutions - a key advantage in the SRS2060 implementation.

What is the forward voltage specification for the SRS2060 at operating conditions?

The SRS2060 specifies a typical forward voltage (VF) of 0.70 V at IF = 10 A and TJ = 25°C, per the Electrical Specifications table. At elevated temperatures (100°C), VF remains stable near 0.65 V due to Schottky characteristics. This value is measured under pulse test conditions (PW = 0.3 ms), and actual system VF depends on thermal management - confirming the SRS2060's low-loss behavior in real-world 20A applications.

Is the SRS2060 compatible with lead-free reflow processes?

Yes, the SRS2060 features matte tin-plated leads qualified per J-STD-002 for solderability and is rated for lead-free reflow profiles up to 260°C peak temperature. Its moisture sensitivity level is Level 1 per J-STD-020, meaning it can be stored indefinitely in dry packs and placed directly into reflow without baking. This ensures high first-pass yield and process robustness for the SRS2060 in modern SMT lines.

How does the guard ring feature in the SRS2060 improve reliability?

The guard ring in the SRS2060 is a diffusion-based edge termination structure that distributes electric field stress away from the active junction periphery. This prevents premature avalanche breakdown under transient overvoltage conditions - such as output short-circuit recovery or input line surges - thereby enhancing long-term reliability in switching power supplies. This structural feature is explicitly documented in the SRS2060 product brief and distinguishes it from basic planar Schottky rectifiers.
