Product details
Overview
SRAS830H from Taiwan Semiconductor is an AEC-Q101-qualified Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 30 V repetitive peak reverse voltage (VRRM), 8 A average forward current (IF), and 150 A non-repetitive surge current (IFSM). It delivers low 0.55 V forward voltage at 8 A and 25°C, enabling high-efficiency DC/DC conversion in automotive lighting and reverse battery protection circuits.
For engineers reviewing the SRAS830H datasheet, SRAS830H pinout, SRAS830H application, or SRAS830H equivalent, key selection factors include its 30 V VRRM, 0.55 V VF @ 8 A, 150 A IFSM, AEC-Q101 qualification, and TO-263AB thermal performance (RθJC = 3°C/W).
Technical Context
The SRAS830H uses a single-die Schottky junction structure optimized for low forward voltage and fast switching, with guard ring design enhancing overvoltage robustness. Its 30 V VRRM and 0.55 V VF balance conduction loss and breakdown margin for 12–24 V automotive systems.
Thermally, it features a low 3°C/W junction-to-case resistance and operates up to +150°C junction temperature. Moisture sensitivity is Level 1 per J-STD-020, and terminals are matte tin-plated for reliable solderability.

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-8EWH03-M3 | Same 30 V VRRM, 8 A IF, but TO-252 (DPAK); RθJC = 4.5°C/W | Limited thermal performance in high-power density layouts | Prefer SRAS830H where board space allows D2PAK and thermal management is critical |
| ON Semiconductor SB830 | 30 V VRRM, 8 A IF, TO-263AB, but AEC-Q101 not claimed; VF = 0.60 V @ 8 A | Not qualified for automotive safety-critical subsystems | Select SRAS830H for AEC-Q101-compliant designs requiring validated reliability |
Compared with VS-8EWH03-M3 and SB830, the SRAS830H offers superior thermal resistance (3°C/W), guaranteed AEC-Q101 qualification, and lower forward voltage-making it preferred for thermally constrained, automotive-grade freewheeling and reverse protection roles.

FAQ
What is the maximum junction temperature rating for the SRAS830H?
The SRAS830H has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This enables reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains case temperature within derating limits defined in the forward current derating curve.
Is the SRAS830H pin-compatible with other parts in the SRAS8xxH series?
Yes, all SRAS8xxH devices-including SRAS830H-share identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout. Voltage ratings differ across the series (20–150 V), but mechanical and soldering requirements remain consistent, allowing common PCB footprint reuse across designs.
Does the SRAS830H require a moisture bake before reflow soldering?
No. The SRAS830H is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and processed using standard lead-free reflow profiles without pre-bake. This simplifies SMT line integration and eliminates yield risk from moisture-induced popcorning.
What is the typical forward voltage of the SRAS830H at 8 A and 125°C?
The SRAS830H exhibits a typical forward voltage of approximately 0.48 V at 8 A and 125°C, based on extrapolation from the published 25°C (0.55 V) and 100°C (0.49 V) data points in the electrical specifications table. This low VF drift supports stable efficiency across full automotive temperature range.
How does the guard ring in the SRAS830H improve reliability?
The guard ring in the SRAS830H mitigates edge breakdown under high dv/dt conditions by shaping the electric field distribution at the die periphery. This design enables stable operation at 10,000 V/μs critical rate of rise, preventing premature avalanche and enhancing robustness in fast-switching automotive inverters and DC/DC converters where the SRAS830H serves as freewheeling or output rectifier.
