Product details
Overview
SS36-E3/9AT from Vishay General Semiconductor is a surface-mount Schottky barrier rectifier rated for 60 V repetitive peak reverse voltage, 3.0 A average forward current, and 100 A non-repetitive surge current, with 0.75 V typical forward voltage at 3.0 A - used in DC/DC converters, freewheeling diode circuits, and polarity protection in automotive and industrial power supplies.
For engineers reviewing the SS36-E3/9AT datasheet, SS36-E3/9AT pinout, SS36-E3/9AT application, or SS36-E3/9AT equivalent, key selection criteria include its SMC (DO-214AB) package, AEC-Q101 qualification eligibility via HE3/HM3 variants, low VF for high-efficiency 12–48 V systems, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This Schottky rectifier operates as a single-anode/cathode unidirectional power device optimized for high-frequency switching applications. Its guardring structure provides overvoltage protection, while the low VF (0.75 V @ 3.0 A) and high IFSM (100 A) support robust transient handling in synchronous buck and flyback topologies.
Thermal performance is defined by RθJA = 55 °C/W (PCB-mounted on 14 mm × 14 mm copper pad) and RθJL = 17 °C/W, enabling reliable operation up to TJ = 150 °C. The device exhibits 20 mJ non-repetitive avalanche energy (IAS = 2.0 A, L = 10 mH), confirming ruggedness under inductive load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - maximum blocking voltage ensures safe operation in 48 V nominal bus systems with 20 % transients |
| IF(AV) | 3.0 A - continuous DC current rating supports medium-power converter outputs without forced cooling |
| VF @ 3.0 A | 0.75 V - low conduction loss reduces power dissipation to ~2.25 W, improving system efficiency |
| IFSM | 100 A - handles 8.3 ms half-sine surges common in motor startup or capacitor charging events |
| EAS | 20 mJ - avalanche energy rating validates reliability during inductive turn-off stress in freewheeling paths |
| TJ max. | 150 °C - extended junction temperature enables use in under-hood automotive environments |
| RθJA | 55 °C/W - thermal resistance measured on standard 14 mm × 14 mm PCB copper pad, guides heatsinking design |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal under forward bias | Connected to lower-potential side (e.g., switch node in buck converter); requires low-inductance layout |

Key Features
| Feature | Design Value |
|---|---|
| Guardring structure | Provides controlled avalanche behavior and enhanced dv/dt immunity (10,000 V/μs rating) |
| Low forward voltage drop | 0.75 V @ 3.0 A minimizes conduction losses in high-duty-cycle DC/DC stages |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without preconditioning or baking |
| AEC-Q101 qualification path | HE3/HM3 variants available for automotive-grade reliability validation (not applicable to E3 suffix) |
| High surge capability | 100 A IFSM enables survival of repeated inrush and fault currents in industrial SMPS |
Applications
| DC/DC Converters | Freewheeling Diodes |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3L60S | Same SMC package, 60 V VRRM, 3 A IF(AV), but VF = 0.72 V @ 3 A; RθJA = 60 °C/W | Slightly lower VF improves efficiency marginally, but higher thermal resistance requires larger copper area | Prefer when minimal conduction loss dominates over thermal layout constraints |
| MBR360T3G | TO-277 package (not SMC), 60 V VRRM, 3 A IF(AV), VF = 0.71 V @ 3 A; AEC-Q101 qualified | Requires PCB footprint change; qualified for automotive use out-of-box (E3 variant is commercial only) | Choose when AEC-Q101 compliance is mandatory and board redesign is acceptable |
Compared with STPS3L60S and MBR360T3G, the SS36-E3/9AT offers standardized SMC footprint compatibility, MSL Level 1 reflow readiness, and verified 150 °C operation - making it optimal for cost-sensitive industrial designs where qualification beyond commercial grade is not required.

FAQ
What is the maximum junction temperature rating for SS36-E3/9AT?
The SS36-E3/9AT has a maximum operating junction temperature (TJ max.) of +150 °C, validated per the Vishay datasheet 88751. This allows deployment in thermally demanding environments such as enclosed industrial enclosures or under-hood automotive locations when mounted on adequate copper area. Derating curves in Figure 1 confirm sustained 3.0 A operation up to 115 °C ambient with standard PCB heatsinking.
Is SS36-E3/9AT AEC-Q101 qualified?
No, the SS36-E3/9AT is a commercial-grade part with RoHS-compliant matte tin plating (E3 suffix). AEC-Q101 qualification applies only to variants with HE3 or HM3 suffixes (e.g., SS36HE3_B/I). The SS36-E3/9AT meets MSL Level 1 and JESD 201 Class 2 whisker resistance, but does not carry automotive qualification documentation or test reports.
What does the "9AT" in SS36-E3/9AT indicate?
The "9AT" suffix denotes the packaging configuration: 13-inch diameter plastic tape and reel, containing 3500 units per reel. This is distinct from "57T", which indicates 7-inch tape-and-reel (850 units). Both share identical electrical and thermal specifications; only the delivery format differs. The base part SS36-E3 remains unchanged across tape sizes.
What is the forward voltage drop of SS36-E3/9AT at 1.5 A?
Per the Vishay datasheet 88751 Figure 3 (Typical Instantaneous Forward Characteristics), the SS36-E3/9AT exhibits approximately 0.65 V forward voltage at 1.5 A and 25 °C junction temperature. At 150 °C, VF drops slightly to ~0.62 V due to negative temperature coefficient of Schottky diodes - a key advantage for thermal stability in high-load conditions.
Can SS36-E3/9AT replace SS34-E3/9AT in a design?
Yes, the SS36-E3/9AT can directly replace SS34-E3/9AT in most cases because both share identical SMC (DO-214AB) package, pinout, thermal characteristics, and 3.0 A IF(AV) rating - differing only in VRRM (60 V vs. 40 V) and VF (0.75 V vs. 0.50 V). Designers must verify that 60 V blocking margin is acceptable and that the higher VF does not exceed thermal budget in the target application.
