Product details
Overview
SS26S-M3/5AT from Vishay General Semiconductor is a surface-mount Schottky barrier rectifier rated for 60 V repetitive peak reverse voltage, 2.0 A average forward current, and 40 A surge capability, with a low 0.53 V forward voltage at 2.0 A and operation up to +150 °C junction temperature-used in DC/DC converters, freewheeling diode circuits, and polarity protection in compact power supplies.
For engineers reviewing the SS26S-M3/5AT datasheet, SS26S-M3/5AT pinout, SS26S-M3/5AT application, or SS26S-M3/5AT equivalent, key selection considerations include its SMA (DO-214AC) package, cathode-band polarity marking, M3 halogen-free RoHS-compliant construction, and thermal resistance of 100 °C/W (junction-to-ambient, PCB-mounted).
Technical Context
This device implements a single-diode Schottky barrier structure optimized for high-frequency switching and low conduction loss. Its guardring design provides overvoltage protection, while the low VF and high IFSM support efficient energy recovery in flyback and synchronous rectification topologies.
Rated for operation from –55 °C to +150 °C, it meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker testing. The matte tin-plated leads ensure solderability per J-STD-002 and JESD 22-B102, and the UL 94 V-0 molding compound supports reliable reflow assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - maximum reverse blocking voltage before breakdown; defines safe operating range in DC/DC output stages |
| IF(AV) | 2.0 A - continuous forward current rating on standard PCB pad; sets minimum trace width and thermal pad requirements |
| IFSM | 40 A - non-repetitive surge current handling; enables robustness against inrush and transient overloads |
| VF @ 2.0 A | 0.53 V - low conduction loss at rated current; reduces power dissipation and improves system efficiency |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance with 0.2" × 0.2" copper pads; informs heatsinking and layout decisions |
| TJ max. | +150 °C - maximum junction temperature; allows operation in high-ambient industrial environments |
| IR @ 60 V | 200 µA @ 25 °C - low leakage ensures minimal standby power loss in battery-backed systems |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, single-diode configuration. Cathode identified by molded color band. Matte tin-plated leads, halogen-free, RoHS-compliant, M3 suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return); must withstand 40 A surge |
| Cathode | Forward current exit point | Marked with color band; connects to higher-potential rail (e.g., output or input bus); carries full load current |
Key Features
| Feature | Design Value |
|---|---|

| Low VF (0.53 V @ 2.0 A) | Reduces conduction loss by ~30% vs. comparable silicon rectifiers, improving thermal margin |
| MSL Level 1 rating | Enables single-pass reflow without moisture sensitivity concerns-no baking required pre-assembly |
| Junction temperature range (–55 to +150 °C) | Supports deployment in automotive under-hood, industrial motor drives, and outdoor power equipment |
| Halogen-free, RoHS-compliant M3 construction | Meets global environmental compliance mandates and supports lead-free manufacturing |
Applications
| DC/DC Converters | Freewheeling Diodes |
|---|---|
Use Scenario: Output rectification in buck, boost, and flyback converters operating at 100 kHz–1 MHz switching frequencies. IC Role / Device Role / Timing Role: Primary unidirectional current path during off-time; recovers stored inductor energy. Use Value: Low VF minimizes conduction loss; high IFSM tolerates peak inductor currents during startup or overload. | Use Scenario: Inductive load snubbing in relay drivers, solenoid controls, and motor H-bridge commutation. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when inductive current is interrupted. Use Value: Fast recovery and low VF reduce voltage spikes and heat generation, extending MOSFET lifetime. |
| Polarity Protection | Low-Voltage Inverters |
Use Scenario: Reverse-voltage blocking at input stage of USB-powered devices, PoE injectors, and portable battery chargers. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-system-rail; blocks reverse current flow. Use Value: 60 V VRRM accommodates 48 V systems with margin; low VF avoids significant input voltage drop. | Use Scenario: High-frequency AC output stage in micro-inverters and solar optimizer modules. IC Role / Device Role / Timing Role: Synchronous rectification element in half-bridge output leg. Use Value: Low junction capacitance (typ. 100 pF @ 4 V) maintains high-frequency performance without excessive switching loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS26H-M3/5AT | Same electrical specs but in SMA (DO-214AC) package with enhanced thermal pad (RθJL = 28 °C/W vs. 100 °C/W RθJA) | Better suited for high-power-density designs requiring lower junction-to-lead thermal resistance | Select SS26H-M3/5AT when board-level thermal management is constrained and lead-frame cooling is available |
| MBR260T3G | 60 V VRRM, 2.0 A IF(AV), but TO-277 package (lower profile than SMA, no leads); VF = 0.65 V @ 2.0 A | Leadless package enables tighter layouts and improved high-frequency EMI behavior | Choose MBR260T3G for space-constrained, high-switching-frequency applications where lead inductance must be minimized |
Compared with SS26S-M3/5AT, SS26H-M3/5AT offers superior thermal conduction via the lead frame, while MBR260T3G trades leaded mounting for lower parasitic inductance-both require layout review but provide viable alternatives depending on thermal or EMI priorities.

FAQ
What is the maximum junction temperature rating for SS26S-M3/5AT?
The SS26S-M3/5AT has a maximum junction temperature (TJ max.) of +150 °C, enabling reliable operation in high-ambient environments such as industrial motor drives and automotive under-dash electronics. This rating is validated per the Vishay datasheet revision 15-May-2020 and applies across the full operating range of –55 °C to +150 °C. Derating curves in Figure 1 confirm usable current capacity down to –55 °C ambient.
Does SS26S-M3/5AT have a halogen-free and RoHS-compliant construction?
Yes, SS26S-M3/5AT uses M3-suffix construction, which is explicitly defined in the Vishay documentation as halogen-free, RoHS-compliant, and commercial-grade. The molding compound meets UL 94 V-0 flammability standards, and terminals are matte tin plated per J-STD-002. These attributes are confirmed in Document Number 89410, Revision 15-May-2020.
What is the forward voltage drop of SS26S-M3/5AT at 2.0 A and 25 °C?
The SS26S-M3/5AT exhibits a typical forward voltage drop (VF) of 0.53 V at 2.0 A and 25 °C, with a maximum of 0.62 V under those conditions. This value is specified in the Electrical Characteristics table of the official Vishay datasheet and reflects the device's low-loss Schottky architecture-critical for minimizing conduction losses in high-efficiency power designs.
Is SS26S-M3/5AT suitable for use in DC/DC converter output rectification?
Yes, SS26S-M3/5AT is specifically recommended for DC/DC converter output rectification, as stated in the "Typical Applications" section of its datasheet. Its 60 V VRRM, 2.0 A IF(AV), low VF, and fast recovery make it well-suited for buck, boost, and flyback topologies operating up to 1 MHz. The SMA package supports automated placement and reflow compatibility.
What does the "5AT" suffix indicate in SS26S-M3/5AT?
The "5AT" suffix in SS26S-M3/5AT denotes the preferred packaging format: 13-inch diameter plastic tape and reel, with a base quantity of 7500 units. This differs from "61T", which specifies a 7-inch reel with 1800 units. Both share identical electrical and mechanical specifications-the suffix solely identifies reel size and quantity for logistics and assembly line feeding.
