Product details
Overview
SRT15 R0G from Taiwan Semiconductor is a 1 A, 50 V Schottky barrier rectifier in TS-1 package, featuring low forward voltage (0.70 V @ 1 A, 25°C), high surge current capability (25 A), and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in compact DC/DC converters requiring high efficiency and thermal robustness.
For engineers reviewing the SRT15 R0G datasheet, SRT15 R0G pinout, SRT15 R0G application, or SRT15 R0G equivalent, key selection criteria include its 50 V repetitive peak reverse voltage, 125°C maximum junction temperature, TS-1 mechanical outline, cathode-band polarity marking, and suitability for space-constrained power conversion designs.
Technical Context
This discrete Schottky diode operates with unidirectional conduction, optimized for high-frequency switching applications where low forward voltage drop and fast recovery are critical. Its single-die TS-1 construction delivers 50°C/W junction-to-ambient thermal resistance and supports 8.3 ms non-repetitive surge currents up to 25 A.
The device exhibits 80 pF junction capacitance at 1 MHz and 4.0 V reverse bias, enabling stable performance in 100–500 kHz SMPS topologies. Reverse leakage remains ≤500 µA at 25°C and ≤5 mA at 100°C under rated 50 V reverse voltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS15 | Same 1 A / 50 V rating, but VF = 0.52 V @ 1 A; TS-1 package; no AEC-Q101 documentation confirmed | Better efficiency in low-voltage, high-current rails; lacks automotive qualification evidence | Select when absolute lowest VF dominates over qualification requirements |
| ON Semiconductor SB150 | 50 V VRRM, 1 A IF, VF = 0.72 V @ 1 A; DO-214AC package; AEC-Q101 qualified | Larger footprint (DO-214AC vs. TS-1); higher RθJA (~65°C/W) demands more PCB copper | Select when legacy DO-214AC layout reuse is prioritized over space savings |
Compared with SS15 and SB150, the SRT15 R0G uniquely balances AEC-Q101 compliance, TS-1 space efficiency, and verified 0.70 V forward voltage-making it optimal for new automotive and industrial designs where board area and qualification are co-constrained.

FAQ
What is the maximum junction temperature rating for the SRT15 R0G?
The SRT15 R0G has a maximum junction temperature (TJ) rating of +125°C, validated across its full operating range. This specification enables reliable use in automotive under-hood applications and enclosed industrial power supplies where ambient temperatures exceed 85°C. The SRT15 R0G maintains specified electrical parameters up to this limit, provided thermal design respects its 50°C/W RθJA.
Does the SRT15 R0G meet AEC-Q101 reliability standards?
Yes, the SRT15 R0G is explicitly AEC-Q101 qualified, as confirmed in Taiwan Semiconductor's official documentation (Version I2104). This includes passing high-temperature operating life (HTOL), temperature cycling (TCT), and high-temperature reverse bias (HTRB) tests. The "R0G" suffix denotes green-compliant packaging but does not affect qualification status-the AEC-Q101 compliance applies to the base SRT15 part.
What is the forward voltage drop of the SRT15 R0G at 1 A and 25°C?
The SRT15 R0G exhibits a typical forward voltage (VF) of 0.70 V at 1 A forward current and 25°C junction temperature, per the Electrical Specifications table in the official datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and represents a key efficiency metric for the SRT15 R0G in continuous conduction mode power stages.
What package type does the SRT15 R0G use, and what are its key mechanical features?
The SRT15 R0G uses the TS-1 surface-mount package-a compact, molded-outline case with pure tin-plated leads. Key mechanical features include UL 94V-0 flammability rating, J-STD-002 solderability compliance, JESD201 Class 2 whisker resistance, and cathode polarity indicated by a visible band. Its weight is approximately 0.200 g.
How does the SRT15 R0G compare to the SRT14 and SRT16 in terms of voltage rating and forward voltage?
The SRT15 R0G is rated for 50 V VRRM, positioned between the 40 V SRT14 and 60 V SRT16. Its typical VF is 0.70 V @ 1 A, matching the SRT16 but higher than the 0.55 V of the SRT12–SRT14 group. This reflects the trade-off between reverse voltage capability and forward conduction loss inherent in Schottky diode design across the SRT12–SRT115 family.
