Product details
Overview
SS16HR3G from Taiwan Semiconductor is a 1A, 60V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, featuring 0.75V forward voltage at 1A/25°C, 40A peak surge current, and 125°C maximum junction temperature. It serves as a low-loss freewheeling or output rectifier in compact DC/DC converters and AC/DC adapters.
For engineers reviewing the SS16HR3G datasheet, SS16HR3G pinout, SS16HR3G application, or SS16HR3G equivalent, key selection criteria include its 60V VRRM, 0.75V VF at rated current, thermal resistance of 28°C/W (junction-to-lead), RoHS/halogen-free compliance, and suitability for high-efficiency, space-constrained power conversion designs.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring protection to enhance ruggedness against transient overvoltage events. Its low forward voltage drop and fast recovery (inherent to Schottky architecture) minimize conduction losses and reduce switching-related EMI in high-frequency SMPS topologies.
The device operates across –55°C to +125°C junction temperature range and exhibits 200μA maximum reverse leakage at 60V and 25°C. Thermal performance is characterized by RθJL = 28°C/W and RθJA = 88°C/W, supporting reliable operation under continuous 1A DC load with appropriate PCB copper area.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS16HE3/73 (Vishay) | Same 60V VRRM, 1A IF, DO-214AC package; VF = 0.72V @ 1A, 25°C; RθJA = 90°C/W | Slightly lower VF but higher thermal resistance; less efficient under sustained load | Prefer SS16HR3G where board-level thermal management is limited |
| SB160-TB (ON Semiconductor) | 60V VRRM, 1A IF, DO-214AC; VF = 0.78V @ 1A, 25°C; IR = 500μA @ 60V, 25°C | Higher leakage reduces standby efficiency; otherwise functionally aligned | Choose SS16HR3G for ultra-low leakage in energy-sensitive standby rails |
Compared with SS16HE3/73 and SB160-TB, SS16HR3G delivers the optimal balance of low forward voltage (0.75V), tight reverse leakage (200μA), and proven thermal performance (28°C/W RθJL) for high-density, thermally constrained power supply designs requiring long-term reliability.

FAQ
What is the maximum junction temperature rating for SS16HR3G?
The SS16HR3G has a maximum junction temperature (TJ) rating of +125°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet revision R2305. This allows operation in ambient environments up to approximately 85°C when mounted on standard FR-4 PCB with 1-inch² 2-oz copper pad, assuming 28°C/W junction-to-lead thermal resistance. Exceeding this limit risks parametric shift and accelerated degradation of the SS16HR3G.
Does SS16HR3G have a halogen-free and RoHS-compliant construction?
Yes, SS16HR3G is explicitly stated as RoHS compliant and halogen-free in the "Features" section of the Taiwan Semiconductor SS12–SS115 datasheet (R2305). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002, confirming full compliance with EU RoHS Directive 2011/65/EU and IEC 61249-2-21 for halogen content.
What is the forward voltage of SS16HR3G at 1A and 100°C junction temperature?
The forward voltage of SS16HR3G is 0.65V at 1A and 100°C junction temperature, as specified in the "ELECTRICAL SPECIFICATIONS" table (page 2, R2305). This value reflects reduced series resistance at elevated temperature and is critical for thermal stability analysis in high-ambient applications such as enclosed adapters or TV power supplies where the SS16HR3G may operate near its TJ limit.
Is SS16HR3G suitable for use in automotive infotainment power supplies?
SS16HR3G is not qualified for automotive applications per the manufacturer's notice on page 8 of the R2305 datasheet, which states: "The products shown herein are not designed for use in medical, life-saving, or life-sustaining applications." While its 125°C TJ max and 40A IFSM meet some under-hood thermal demands, SS16HR3G lacks AEC-Q101 qualification, PPAP documentation, and guaranteed automotive-grade lot traceability required for infotainment systems.
What packaging format is used for SS16HR3G and how many units are supplied per reel?
SS16HR3G is supplied in DO-214AC (SMA) package on 7,500-unit tape-and-reel format, as confirmed in the "ORDERING INFORMATION" section (page 3, R2305). The reel complies with EIA-481 standards and supports automated SMT placement. Each reel contains 7,500 SS16HR3G units, with standard carrier tape width and pocket dimensions matching JEDEC DO-214AC mechanical specifications.
