Product details
Overview
SS16/1 from Vishay General Semiconductor is a surface-mount Schottky barrier rectifier in SMA (DO-214AC) package, rated for 60 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 40 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (0.75 V at 1.0 A), operates up to +150 °C junction temperature, and is used in DC/DC converters and polarity protection circuits.
For engineers reviewing the SS16/1 datasheet, SS16/1 pinout, SS16/1 application, or SS16/1 equivalent, key selection criteria include its 60 V VRRM, 0.75 V VF at 1.0 A, SMA package thermal resistance (RθJA = 88 °C/W), AEC-Q101 qualification availability, and suitability for high-frequency, low-loss rectification in space-constrained power designs.
Technical Context
The SS16/1 implements a single-diode Schottky junction with guardring structure for overvoltage robustness and meets MSL Level 1 per J-STD-020 with 260 °C peak reflow tolerance. Its low VF and high IFSM enable efficient operation in high-switching-frequency topologies such as synchronous buck converters.
Designed for surface-mount assembly on PCBs with 5.0 mm × 5.0 mm copper pads, the device exhibits RθJL = 28 °C/W and supports automated placement. Polarity is marked by a cathode band; terminals are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR160-E3/52T | Same SMA package, 60 V VRRM, but higher VF (0.82 V @ 1 A) and lower IFSM (30 A) | Suitable for less demanding surge environments; slightly lower efficiency at full load | Select when cost sensitivity outweighs marginal efficiency gain and surge margin is not critical |
| SS60HE3_A/H | Same Vishay family, AEC-Q101 qualified, identical VRRM/VF/IF(AV), but different marking and tape/reel packaging | Drop-in replacement where automotive qualification is mandatory and traceability is required | Choose for automotive production programs requiring certified reliability documentation and lot traceability |
Compared with MBR160-E3/52T, SS16/1 offers lower conduction loss and higher surge tolerance; compared with SS60HE3_A/H, it shares electrical specs but lacks formal AEC-Q101 certification unless ordered with HE3 suffix-making SS16/1 ideal for commercial-grade high-efficiency power conversion where qualification overhead is unnecessary.

FAQ
What is the maximum junction temperature rating for SS16/1?
The SS16/1 has a maximum operating junction temperature (TJ) of +150 °C, verified per Vishay Document Number 88746. This rating allows reliable operation in thermally demanding environments such as enclosed power supplies or automotive under-dash modules. Derating curves in the SS16/1 datasheet define safe current limits above 125 °C ambient, and the device maintains specified VF and leakage performance within this range.
Is SS16/1 RoHS-compliant and halogen-free?
Yes, SS16/1 is available in both RoHS-compliant commercial-grade (suffix -E3) and halogen-free RoHS-compliant (suffix -M3) variants. The base part number SS16/1 corresponds to the commercial-grade version; ordering codes like SS16-M3/61T explicitly denote halogen-free construction. All versions meet JESD 201 Class 2 whisker testing and UL 94 V-0 flammability requirements.
Does SS16/1 have AEC-Q101 qualification?
The SS16/1 itself is not inherently AEC-Q101 qualified; qualification applies only to specific ordering variants such as SS16HE3_B/H or SS16HM3_B/I, which carry the HE3 or HM3 suffix. These versions undergo additional stress testing and traceability controls per AEC-Q101. Standard SS16/1 (e.g., SS16-E3/61T) is commercial-grade and intended for non-automotive applications unless explicitly ordered with automotive suffixes.
What is the forward voltage drop of SS16/1 at 1.0 A?
The SS16/1 exhibits a maximum instantaneous forward voltage (VF) of 0.75 V at 1.0 A and 25 °C, as specified in Vishay Document Number 88746. This value is measured under pulsed conditions (300 μs, 1 % duty cycle) to minimize self-heating effects. At elevated temperatures or continuous DC operation, VF decreases slightly due to negative temperature coefficient of Schottky junctions.
What package type does SS16/1 use and what are its key mechanical features?
SS16/1 uses the SMA (DO-214AC) surface-mount package, featuring a low-profile molded case compliant with UL 94 V-0 flammability rating. Key mechanical attributes include matte tin-plated leads solderable per J-STD-002, cathode identification via color band, and dimensions of 4.93 mm × 2.54 mm × 2.29 mm (L × W × H). The package supports MSL Level 1 handling and 260 °C peak reflow per J-STD-020.
