Taiwan Semiconductor Corporation SRS2030

Overview

SRS2030 from Taiwan Semiconductor is a 20A, 30V repetitive peak reverse voltage Schottky barrier rectifier in TO-263AB (D2PAK) package, designed for high-efficiency DC/DC conversion and SMPS secondary-side rectification with low forward voltage drop and high surge current capability.

For engineers reviewing the SRS2030 datasheet, SRS2030 pinout, SRS2030 application, or SRS2030 equivalent, key selection criteria include its 0.55 V forward voltage at 10 A/25°C, 200 A non-repetitive surge rating, 1.5 °C/W junction-to-case thermal resistance, and dual-die configuration enabling high-current handling in compact surface-mount form.

Technical Context

The SRS2030 employs a dual-die Schottky barrier structure housed in a single TO-263AB (D2PAK) package, delivering 20 A average forward current with thermal performance optimized via low R_θJC of 1.5 °C/W. Its guard ring design provides overvoltage protection while maintaining fast switching behavior and low reverse recovery charge.

Rated for operation up to +150°C junction temperature, the device supports high-density power designs requiring robust surge immunity (200 A I_FSM, 8.3 ms half-sine) and moisture-insensitive assembly (J-STD-020 Level 1). Reverse leakage remains ≤500 µA at 25°C and ≤15 mA at 100°C under rated V_RRM.

FAQ

What is the maximum junction temperature rating for the SRS2030?

The SRS2030 has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows sustained operation in high-ambient environments such as enclosed power supplies or industrial control cabinets. Derating curves confirm usable current capacity down to 12 A at 100°C case temperature. The SRS2030 must be mounted on adequate copper area to maintain this limit under full 20 A load.

Does the SRS2030 have a guard ring structure, and what benefit does it provide?

Yes, the SRS2030 incorporates a guard ring for overvoltage protection, explicitly stated in its features list. This structure improves edge termination uniformity and suppresses premature avalanche breakdown during voltage transients. In practice, this increases reliability in flyback or LLC resonant converters where reflected spikes may exceed nominal V_RRM. The guard ring is integral to the SRS2030 die design and not present in many competing 30 V Schottky rectifiers.

Is the SRS2030 suitable for automated SMT assembly, and what is its moisture sensitivity level?

Yes, the SRS2030 is explicitly designed for automated placement, as confirmed in its features list. It carries J-STD-020 Moisture Sensitivity Level 1, meaning it can be stored indefinitely at ambient conditions and requires no baking prior to reflow soldering. Its matte tin-plated leads also comply with J-STD-002 for solderability, ensuring consistent wetting and joint integrity in high-volume SMT lines using standard lead-free profiles.

What is the forward voltage specification for the SRS2030, and under what test conditions is it measured?

The SRS2030 has a typical forward voltage (V_F) of 0.55 V at 10 A and 25°C junction temperature, per electrical specifications table. This value is measured using a pulse test with 0.3 ms pulse width to avoid self-heating effects. At elevated temperatures (e.g., 100°C), V_F decreases slightly, improving conduction efficiency in thermally stressed operation. The SRS2030's low V_F directly contributes to reduced power loss versus higher-V_F alternatives like the SB2030 or VS-20CPH03-M3.

How is the dual-die configuration of the SRS2030 implemented electrically and thermally?

The SRS2030 integrates two independent Schottky dies sharing a common cathode terminal (Pin 2), with separate anode terminals (Pins 1 and 3). Electrically, this enables parallel current paths without external paralleling components. Thermally, both dies bond to the same copper tab, allowing combined heat dissipation through a single low-R_θJC path of 1.5 °C/W. This architecture is confirmed in the "Configuration: Dual dies" line of the KEY PARAMETERS section and distinguishes the SRS2030 from single-die equivalents such as the SRS2030's sibling SRS2030-1 (not offered).
