Product details
Overview
SRA8100HC0G from Taiwan Semiconductor is an AEC-Q101-qualified 8A, 100V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.85 V at 8 A, 25°C), high surge current capability (150 A), and guard ring overvoltage protection-used in automotive-grade DC/DC converters and industrial SMPS.
For engineers reviewing the SRA8100HC0G datasheet, SRA8100HC0G pinout, SRA8100HC0G application, or SRA8100HC0G equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 5 mA reverse leakage at 125°C, junction-to-case thermal resistance of 4°C/W, and RoHS/halogen-free compliance for under-hood power conversion designs.
Technical Context
This single-die Schottky rectifier operates with a maximum junction temperature of +150°C and supports repetitive reverse voltages up to 100 V. Its dv/dt rating of 10,000 V/µs ensures robustness against fast transient voltage spikes in switching circuits.
The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD 201 Class 2 whisker resistance. Its TO-220AC case delivers mechanical stability and thermal performance suitable for bolt-down heatsink mounting in high-reliability power supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH10FN-M3 | Same 100 V VRRM, 8 A IF, TO-220AC; VF = 0.79 V @ 8 A, 25°C; lower IR (50 µA @ 100 V) | Not AEC-Q101 qualified; intended for commercial/industrial use only | Select when automotive qualification is not required and lower leakage is prioritized |
| ON Semiconductor MUR8100CT | 100 V, 8 A, TO-220AC; ultrafast recovery (trr = 75 ns); higher VF (1.15 V) and IR (100 µA) | Designed for high-frequency switching; less efficient in low-VF-dominated applications | Select when fast reverse recovery is needed over conduction loss minimization |
Compared with VS-8EWH10FN-M3 and MUR8100CT, the SRA8100HC0G uniquely balances automotive qualification, low forward voltage, and controlled leakage-making it optimal for thermally constrained, safety-critical 100 V rectification where efficiency and reliability are jointly prioritized.

FAQ
What is the maximum junction temperature rating for the SRA8100HC0G?
The SRA8100HC0G has a maximum junction temperature (TJ) rating of +150°C, verified per its absolute maximum ratings table. This enables operation in high-ambient-temperature environments such as automotive engine bays or enclosed industrial power supplies. The SRA8100HC0G's thermal performance is further supported by a junction-to-case resistance of 4°C/W, allowing effective heat transfer to external heatsinks.
Is the SRA8100HC0G pin-compatible with other devices in the SRA8xxx family?
Yes-the SRA8100HC0G shares identical TO-220AC package dimensions, pinout, and mechanical mounting features with all SRA8xxx variants (e.g., SRA850HC0G, SRA8150HC0G). All devices use the same center-anode tab configuration and non-functional lead 1, enabling layout reuse across voltage grades within the family. The SRA8100HC0G maintains consistent mechanical compatibility without requiring PCB redesign.
Does the SRA8100HC0G meet automotive qualification standards?
Yes-the "H" suffix in SRA8100HC0G explicitly denotes AEC-Q101 qualification, confirmed in the ordering information and features section of the official datasheet. This certification covers stress testing for temperature cycling, humidity bias, and mechanical shock-validating suitability for automotive power electronics including body control modules and ADAS subsystems. The SRA8100HC0G is not just automotive-capable; it is formally qualified.
What is the forward voltage specification for the SRA8100HC0G at full rated current?
The SRA8100HC0G exhibits a typical forward voltage (VF) of 0.85 V at 8 A and 25°C, as specified in the electrical characteristics table. This value is measured under pulsed conditions (PW = 0.3 ms) to minimize self-heating effects. At higher junction temperatures (e.g., 125°C), VF decreases slightly-consistent with Schottky diode behavior-and remains below 0.80 V, preserving efficiency in thermally loaded systems using the SRA8100HC0G.
How does the guard ring feature improve reliability in the SRA8100HC0G?
The guard ring structure in the SRA8100HC0G mitigates edge breakdown under high-voltage transients by distributing electric field stress away from the active junction periphery. This design enhances ruggedness during rapid voltage transitions (dv/dt up to 10,000 V/µs), preventing premature avalanche failure in switching-mode applications. In real-world use, this directly extends service life in noisy power conversion circuits where the SRA8100HC0G serves as the primary output rectifier.
