Product details
Overview
SRT15HR0G from Taiwan Semiconductor is a 1 A, 50 V AEC-Q101-qualified Schottky barrier rectifier in TS-1 package, featuring 0.70 V forward voltage at 1 A and 25 A surge current capability; used in automotive-grade DC/DC converters and industrial SMPS where low conduction loss and high reliability are required.
For engineers reviewing the SRT15HR0G datasheet, SRT15HR0G pinout, SRT15HR0G application, or SRT15HR0G equivalent, key selection criteria include its 50 V repetitive peak reverse voltage, 125 °C maximum junction temperature, AEC-Q101 qualification status, TS-1 mechanical outline, and cathode-band polarity marking.
Technical Context
This Schottky rectifier employs a single-die construction with guard ring structure for overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its thermal resistance is 50 °C/W (junction-to-ambient), enabling stable operation up to 125 °C junction temperature under rated DC current.
Electrical behavior is defined by low VF (0.70 V typ. @ 1 A, 25 °C), low IR (500 µA max. @ 50 V, 25 °C), and junction capacitance of 80 pF @ 4 V - characteristics optimized for high-frequency switching efficiency in compact power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse blocking voltage; sets upper limit for input/output rail isolation in buck or flyback topologies |
| IF | 1 A continuous - average forward current rating; defines steady-state power delivery capacity without derating |
| IFSM | 25 A - non-repetitive surge current handling; supports inrush and transient overload conditions in adapter inputs |
| VF | 0.70 V typ. @ 1 A, 25 °C - low conduction loss directly reduces heat generation and improves system efficiency |
| TJ max | 125 °C - maximum operating junction temperature; enables use in under-hood automotive environments |
| CJ | 80 pF @ 1 MHz, 4 V - low junction capacitance minimizes switching losses and EMI in high-frequency converters |

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-1EWH05-M3/5AT | Same 1 A / 50 V rating, but TO-277 package; VF = 0.55 V typ., higher IR (1 mA @ 50 V) | TO-277 offers better thermal dissipation but larger footprint; less suitable for ultra-thin automotive modules | Select when board-level thermal management allows larger package and lower VF is prioritized over AEC-Q101 compliance |
| ON Semiconductor SB150 | 1 A / 50 V, DO-214AA package; VF = 0.75 V typ.; not AEC-Q101 qualified; TJ max = 125 °C | DO-214AA lacks automotive qualification and has higher VF; suited for cost-sensitive industrial adapters only | Choose for non-automotive designs where qualification overhead is unnecessary and legacy DO-214AA footprint is fixed |
Compared with VS-1EWH05-M3/5AT and SB150, the SRT15HR0G uniquely combines AEC-Q101 qualification, TS-1 space efficiency, and balanced VF/IR trade-off - making it the preferred choice for next-generation automotive and industrial power supplies demanding both reliability and miniaturization.

FAQ
What is the peak repetitive reverse voltage rating for SRT15HR0G?
The SRT15HR0G has a repetitive peak reverse voltage (VRRM) rating of 50 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2104), where SRT15 corresponds to the 50 V variant in the SRT12–SRT115 series. It defines the maximum DC or sinusoidal AC reverse voltage the device can block continuously without breakdown.
Is SRT15HR0G qualified to AEC-Q101 standards?
Yes, SRT15HR0G is AEC-Q101 qualified. The "H" suffix in the ordering code explicitly denotes AEC-Q101 qualification per the Ordering Information section of the Taiwan Semiconductor datasheet. This certification covers stress tests including HTGB, HTRB, TCT, and ESD, validating suitability for automotive electronic systems.
What package type does SRT15HR0G use, and what are its key mechanical features?
SRT15HR0G uses the TS-1 surface-mount package. Key mechanical features include UL 94V-0 flammability-rated molding compound, pure tin-plated leads compliant with J-STD-002, cathode polarity marked by a visible band, and a mass of approximately 0.200 g. The TS-1 outline is documented in the Package Outline Dimensions section of the datasheet.
What is the typical forward voltage drop of SRT15HR0G at rated current?
The typical forward voltage drop (VF) of SRT15HR0G is 0.70 V at IF = 1 A and TJ = 25 °C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects low conduction loss essential for high-efficiency power conversion.
Does SRT15HR0G have a guard ring structure, and what benefit does it provide?
Yes, SRT15HR0G incorporates a guard ring structure, explicitly listed under FEATURES in the datasheet. This design enhances edge termination robustness, improving resistance to avalanche breakdown during transient overvoltage events such as load dump or inductive switching spikes - critical for automotive and industrial reliability.
