Product details
Overview
SRT13 R0G from Taiwan Semiconductor is a 1 A, 30 V Schottky barrier rectifier in TS-1 package, featuring low forward voltage (0.55 V at 1 A, 25°C), high surge current capability (25 A), and AEC-Q101 qualification for automotive-grade reliability. It delivers high efficiency in compact DC/DC converters and AC/DC adapters.
For engineers reviewing the SRT13 R0G datasheet, SRT13 R0G pinout, SRT13 R0G application, or SRT13 R0G equivalent, key selection criteria include its 30 V repetitive peak reverse voltage, 125°C maximum junction temperature, TS-1 mechanical outline, cathode-band polarity marking, and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring technology to enhance overvoltage robustness. Its low VF and 50 °C/W junction-to-ambient thermal resistance support thermally constrained board layouts in high-frequency switching topologies.
Designed for unidirectional power conversion, it operates across -55°C to +125°C junction range (with storage up to +150°C) and exhibits 500 µA max reverse leakage at 30 V and 25°C, dropping to 10 mA at 100°C - critical for thermal stability in SMPS output stages.

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-1EQH03-M3/45 | Same 30 V VRRM, 1 A IF, but TO-277 package (larger footprint, higher RθJA = 65 °C/W) | Less suitable for ultra-compact layouts; requires larger pad area and thermal relief | Prefer SRT13 R0G when board space or thermal resistance below 55 °C/W is critical |
| ON Semiconductor SB130 | 30 V VRRM, 1 A IF, DO-214AA package; VF = 0.52 V (slightly lower), but no AEC-Q101 qualification | Not approved for automotive use; limited to commercial/industrial environments | Select SRT13 R0G for automotive designs requiring AEC-Q101; choose SB130 only if qualification is unnecessary and VF < 0.53 V is prioritized |
Compared with VS-1EQH03-M3/45 and SB130, the SRT13 R0G uniquely combines AEC-Q101 qualification, TS-1 compactness (0.200 g), and 50 °C/W thermal resistance - making it optimal for space-constrained automotive and industrial power supplies where reliability and thermal performance are jointly critical.

FAQ
What is the maximum junction temperature rating for the SRT13 R0G?
The SRT13 R0G has a maximum junction temperature (TJ) of +125°C under normal operating conditions. This rating applies to continuous operation and is validated per the device's absolute maximum ratings table. Derating is required above this temperature, and the device must not exceed +125°C during sustained conduction to maintain reliability and avoid parametric shift. The SRT13 R0G also supports storage up to +150°C.
Is the SRT13 R0G AEC-Q101 qualified?
Yes, the SRT13 R0G is AEC-Q101 qualified. The "R0G" suffix indicates RoHS-compliant, halogen-free, and AEC-Q101-qualified version per Taiwan Semiconductor's ordering nomenclature. This qualification covers stress testing for temperature cycling, humidity bias, and high-temperature operating life - confirming suitability for automotive underhood and cabin applications.
What does the "R0G" suffix mean in SRT13 R0G?
The "R0G" suffix in SRT13 R0G denotes RoHS-compliant, halogen-free packaging using UL 94V-0 molding compound and pure tin-plated leads. It also signifies AEC-Q101 qualification. This distinguishes it from non-automotive variants like SRT13 (no suffix) or SRT13H (AEC-Q101 but not necessarily halogen-free). The SRT13 R0G is specifically intended for environmentally regulated and automotive-grade deployments.
What is the forward voltage drop of the SRT13 R0G at rated current?
The SRT13 R0G exhibits a typical forward voltage (VF) of 0.55 V at 1 A forward current and 25°C junction temperature. This value is measured under pulsed conditions (0.3 ms pulse width) and represents the conduction loss under nominal load. At elevated temperatures (e.g., 100°C), VF decreases slightly, improving efficiency in thermally stressed operation.
Does the SRT13 R0G have a specified junction-to-ambient thermal resistance?
Yes, the SRT13 R0G has a typical junction-to-ambient thermal resistance (RθJA) of 50 °C/W, measured on standard JEDEC 2-layer test board conditions. This value is critical for thermal design - for example, at 1 A and 0.55 V drop (0.55 W dissipation), the junction rise above ambient is ~27.5°C. Layout enhancements (copper pour, thermal vias) can improve actual performance beyond this baseline.
