Taiwan Semiconductor Corporation SRS10100

Overview

SRS10100 from Taiwan Semiconductor is a 10A, 100V Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring dual-die construction, 120A surge capability, 0.90V forward voltage at 5A/25°C, and 100µA reverse leakage at rated VR/25°C. It serves as a high-efficiency output rectifier in DC-DC converters and SMPS secondary-side circuits.

For engineers reviewing the SRS10100 datasheet, SRS10100 pinout, SRS10100 application, or SRS10100 equivalent, key selection factors include its 100V VRRM rating, thermal resistance of 2°C/W (junction-to-case), 125°C max operating junction temperature, and compatibility with automated SMT placement per J-STD-002 solderability standards.

Technical Context

The SRS10100 employs dual Schottky die in a single TO-263AB package to deliver 10A continuous forward current with low conduction loss. Its 100V repetitive peak reverse voltage and 70V RMS reverse voltage support mid-range industrial and telecom power supplies.

Thermal performance is defined by a 2°C/W junction-to-case resistance and operation up to 125°C (with derating above 80°C case temperature). Reverse leakage remains ≤100µA at 25°C and ≤5mA at 125°C, enabling stable performance in thermally constrained environments.

FAQ

What is the maximum junction temperature rating for the SRS10100?

The SRS10100 has a maximum junction temperature (TJ max) of 125°C, as specified in its absolute maximum ratings table. This rating applies under continuous operation with appropriate thermal management. Derating is required above 80°C case temperature, per the forward current derating curve in the datasheet. The SRS10100 must not exceed 125°C at the silicon junction during operation to ensure reliability and lifetime compliance.

Does the SRS10100 support automated pick-and-place assembly?

Yes, the SRS10100 supports automated placement per industry standards. Its TO-263AB (D2PAK) package features matte tin-plated leads compliant with J-STD-002 for solderability, and its moisture sensitivity level is rated J-STD-020 Level 1-meaning it has unlimited floor life and requires no pre-baking before reflow. These attributes make the SRS10100 fully compatible with high-speed SMT lines used in volume manufacturing of power supplies.

What is the forward voltage of the SRS10100 under typical operating conditions?

The SRS10100 exhibits a typical forward voltage (VF) of 0.90 V at 5A and 25°C junction temperature, as measured under pulsed conditions (PW = 0.3ms). At higher temperatures or currents, VF decreases slightly due to negative temperature coefficient behavior of Schottky diodes. This value directly determines conduction loss and thermal dissipation in the SRS10100 during steady-state operation in power conversion circuits.

How does the SRS10100 handle surge current events?

The SRS10100 is rated for a non-repetitive peak forward surge current (IFSM) of 120A for an 8.3ms single half-sine wave, superimposed on rated load. This capability enables robust handling of inrush currents during power-up, short-circuit transients, and line surges in SMPS and DC-DC applications. The dual-die construction and low RθJC help distribute and dissipate surge energy effectively, preserving device integrity across repeated stress events.

Is the SRS10100 halogen-free and RoHS compliant?

Yes, the SRS10100 is both halogen-free in accordance with IEC 61249-2-21 and RoHS compliant. Its molding compound contains no brominated or chlorinated flame retardants, and all homogeneous materials meet EU Directive 2011/65/EU restrictions on hazardous substances. This compliance supports use in environmentally regulated industrial, telecom, and computing equipment sold globally.
