Product details
Overview
SS16 R3G 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 output rectifier in DC/DC converters and AC/DC adapters.
For engineers reviewing the SS16 R3G datasheet, SS16 R3G pinout, SS16 R3G application, or SS16 R3G 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 SMPS designs operating up to 125°C junction temperature.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring structure for enhanced overvoltage ruggedness. Its low forward voltage drop and fast switching speed stem from platinum-silicide or similar Schottky barrier metallization, enabling high-conversion efficiency in continuous conduction mode (CCM) and critical conduction mode (CrCM) topologies.
The device operates across -55°C to +125°C junction range, with thermal performance defined by RθJL = 28°C/W and RθJA = 88°C/W. Reverse leakage remains ≤5mA at 100°C and rated 60V reverse bias, supporting stable operation in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for output rectification in 48V-input DC/DC or 24V-output SMPS |
| IF | 1 A - Continuous forward current rating; defines steady-state power delivery capability without derating at TA ≤ 50°C |
| VF @ 1A, 25°C | 0.75 V - Forward voltage drop; determines conduction loss (0.75W at 1A), directly impacting thermal design and efficiency |
| IFSM | 40 A - Non-repetitive peak surge current (8.3ms half-sine); supports robustness against input line transients and startup inrush |
| TJ max | 125 °C - Maximum allowable junction temperature; constrains heatsinking requirements and ambient operating envelope |
| RθJL | 28 °C/W - Junction-to-lead thermal resistance; enables accurate thermal modeling when mounted on copper pour or thermal pad |
| IR @ 60V, 100°C | 5 mA - Reverse leakage current; affects standby power loss and stability in high-impedance feedback networks |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB160-E3/52T (Vishay) | Same 60V VRRM, 1A IF, but VF = 0.72V @ 1A/25°C; RθJA = 90°C/W vs. 88°C/W | Identical DO-214AC footprint; slightly lower VF yields marginal efficiency gain in low-ambient designs | Preferred where sub-10mV VF reduction justifies alternate sourcing; identical layout compatibility |
| SS16HE3_A/H (ON Semiconductor) | 60V VRRM, 1A IF, VF = 0.75V @ 1A/25°C; TJmax = 150°C vs. 125°C; RθJL = 25°C/W | Higher temperature rating supports extended life in sealed monitor enclosures; tighter thermal resistance improves power density | Select when operating ambient exceeds 70°C or long-term reliability at elevated TJ is critical |
Compared with SS16 R3G, SB160 offers marginally lower conduction loss but no thermal advantage, while SS16HE3_A/H provides superior thermal performance and 25°C higher junction rating-enabling longer lifetime in thermally aggressive applications without layout change.

FAQ
What is the maximum junction temperature rating for SS16 R3G?
The SS16 R3G has a maximum junction temperature (TJ) rating of +125°C. This value is specified in the Absolute Maximum Ratings table and applies under continuous forward conduction. Operation beyond this temperature risks irreversible degradation of the Schottky barrier and increased reverse leakage. Derating curves in the datasheet define safe IF limits above 25°C ambient, and thermal design must ensure junction temperature stays within this bound under worst-case load and ambient conditions for SS16 R3G.
Does SS16 R3G have a lead-free and RoHS-compliant finish?
Yes, SS16 R3G features matte tin-plated leads and is fully RoHS compliant and halogen-free per EU Directive 2015/863. The device meets J-STD-002 solderability requirements and carries moisture sensitivity level 1 (MSL-1), meaning it can be used directly from tape-and-reel packaging without pre-baking. These attributes are confirmed in the Mechanical Data and Features sections of the official Taiwan Semiconductor SS12–SS115 datasheet revision R2305 for SS16 R3G.
What is the forward voltage of SS16 R3G at 1A and 100°C junction temperature?
The forward voltage (VF) of SS16 R3G is 0.65V at 1A forward current and 100°C junction temperature. This value is specified in the Electrical Specifications table under "Forward voltage" with condition "IF = 1A, TJ = 100°C". It reflects reduced barrier height at elevated temperature and is critical for calculating conduction loss and thermal feedback in high-temperature operating environments for SS16 R3G.
Is SS16 R3G compatible with automated pick-and-place equipment?
Yes, SS16 R3G is explicitly designed for automated placement, as stated in its Features list. Its DO-214AC (SMA) package has standardized dimensions, matte tin-plated leads with proven solderability per J-STD-002, and a clear cathode band for optical recognition. The MSL-1 rating eliminates bake requirements, streamlining SMT line integration. These characteristics make SS16 R3G suitable for high-throughput manufacturing without process modification.
What is the peak non-repetitive forward surge current rating for SS16 R3G?
The peak non-repetitive forward surge current (IFSM) for SS16 R3G is 40A, tested per an 8.3ms single half-sine wave superimposed on rated load. This rating is defined in the Absolute Maximum Ratings table and ensures robustness against line transients, capacitor inrush, and short-duration overload events. Designers should verify that PCB trace width and thermal mass can handle this surge without exceeding the 125°C junction limit during the pulse for SS16 R3G.
