Product details
Overview
SR010 A0G from Taiwan Semiconductor is a 0.5A, 100V Schottky barrier rectifier in DO-204AL (DO-41) package, featuring VF = 0.85 V at IF = 0.5 A and IR = 100 µA at TJ = 25°C, with 30 A surge capability and 125°C/150°C max junction temperature. It serves as a high-efficiency output rectifier in compact DC-DC converters.
For engineers reviewing the SR010 A0G datasheet, SR010 A0G pinout, SR010 A0G application, or SR010 A0G equivalent, key selection criteria include reverse voltage rating, forward voltage drop at rated current, leakage current at elevated temperature, thermal resistance (RθJA = 50°C/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This discrete Schottky diode uses a single-die construction optimized for low conduction loss in low-voltage, medium-current switching applications. Its guard ring structure enhances overvoltage robustness, while pure tin-plated leads ensure J-STD-002 solderability and JESD201 Class 2 whisker resistance.
The device operates across -55°C to +150°C storage range and supports continuous forward current up to 0.5 A with derating above 25°C ambient. Junction capacitance is 65 pF at 1 MHz and 4.0 V reverse bias, enabling stable high-frequency rectification in SMPS topologies.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for SR010 A0G?
The SR010 A0G has a VRRM rating of 100 V, meaning it can reliably block up to 100 V of reverse voltage in repetitive operation without breakdown. This rating is confirmed in the Absolute Maximum Ratings table on page 2 of the official TSC datasheet (Version H2104), and applies across the full operating temperature range.
Is SR010 A0G AEC-Q101 qualified?
SR010 A0G itself is not AEC-Q101 qualified; however, the SR010H and SR010HA0G variants are explicitly listed as AEC-Q101 qualified in the Ordering Information section. The "H" suffix denotes qualification, so SR010 A0G is the standard industrial-grade version without automotive validation.
What is the forward voltage drop of SR010 A0G at 0.5A and 25°C?
The SR010 A0G exhibits a typical forward voltage drop (VF) of 0.85 V at IF = 0.5 A and TJ = 25°C, as specified in the Electrical Specifications table on page 3 of the TSC datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) to minimize self-heating effects.
Does SR010 A0G have a guard ring structure?
Yes, SR010 A0G incorporates a guard ring structure for overvoltage protection, as stated in the FEATURES section of the TSC datasheet. This design feature enhances edge termination robustness and improves resistance to transient voltage spikes without requiring external protection components.
What is the junction-to-ambient thermal resistance (RθJA) for SR010 A0G in DO-41 package?
The junction-to-ambient thermal resistance (RθJA) for SR010 A0G is 50°C/W, as published in the Thermal Performance section of the TSC datasheet. This value assumes standard JEDEC test conditions (single device on FR-4 board with 1 in² copper area) and is critical for calculating allowable power dissipation at given ambient temperatures.
