Product details
Overview
SS8P3L-E3/86A from Vishay General Semiconductor is a high-current-density surface-mount Schottky barrier rectifier rated for 30 V repetitive peak reverse voltage, 8.0 A average forward current, and 150 A non-repetitive surge current; it delivers 0.472 V forward voltage at 8.0 A and 125 °C, enabling efficient low-voltage DC-DC conversion in space-constrained power supplies.
For engineers reviewing the SS8P3L-E3/86A datasheet, SS8P3L-E3/86A pinout, SS8P3L-E3/86A application, or SS8P3L-E3/86A equivalent, key selection criteria include its TO-277A (SMPC) package, 3.5 °C/W junction-to-lead thermal resistance, AEC-Q101 qualification status (via HE3/HM3 variants), and suitability for freewheeling and polarity protection in automotive and industrial converters.
Technical Context
This Schottky rectifier uses a planar metal-silicon junction to achieve low forward voltage and fast switching with no minority-carrier storage delay. Its 30 V VRRM, 8.0 A IF(AV), and 20 mJ EAS rating support robust operation in high-frequency synchronous rectification and flyback snubber circuits.
The device features a thermally optimized TO-277A (SMPC) package with dual anode terminals and a common cathode, delivering 60 °C/W junction-to-ambient and only 3.5 °C/W junction-to-lead thermal resistance when mounted on a 1 oz. copper PCB pad per Vishay's recommended layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SB830 | Same TO-277A package, 30 V VRRM, but 0.52 V VF @ 8 A/125 °C; higher RθJA (65 °C/W) | Limited to lower ambient or forced-air cooled designs due to higher thermal resistance | Prefer SS8P3L-E3/86A where board-level thermal management is passive or space-limited |
| Diodes Inc. SBRA830 | TO-277A, 30 V, 8 A, but 0.55 V VF @ 8 A/125 °C; no AEC-Q101 variant available | Not suitable for automotive under-hood deployment requiring AEC-Q101 qualification | Select SS8P3L-E3/86A for commercial use or SS8P3LHE3/86A for automotive-compliant designs |
Compared with SB830 and SBRA830, SS8P3L-E3/86A offers the lowest forward voltage and best thermal resistance in the TO-277A 8 A class, making it optimal for high-efficiency, thermally constrained, or automotive-qualified applications where conduction loss and junction temperature are critical.

FAQ
What is the maximum junction temperature rating for SS8P3L-E3/86A?
The SS8P3L-E3/86A has a maximum operating junction temperature of +150 °C, verified per Vishay Document Number 89001. This rating enables reliable operation in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies. Derating curves in Figure 1 confirm 8.0 A IF(AV) is sustainable up to 125 °C ambient with appropriate PCB copper area. The SS8P3L-E3/86A must not exceed this limit to maintain long-term reliability and parametric stability.
Does SS8P3L-E3/86A meet automotive qualification standards?
The SS8P3L-E3/86A itself is the commercial-grade RoHS-compliant variant (E3 suffix). It is not AEC-Q101 qualified. However, the SS8P3LHE3/86A variant-identical in electrical specs and package-is explicitly qualified to AEC-Q101 for automotive applications. Engineers requiring automotive compliance must specify the HE3 suffix version; SS8P3L-E3/86A remains suitable for industrial and computing applications where AEC-Q101 is not mandated.
What is the forward voltage of SS8P3L-E3/86A at 8.0 A and 125 °C?
The SS8P3L-E3/86A exhibits a typical forward voltage of 0.472 V at 8.0 A and 125 °C, as specified in the Electrical Characteristics table of Vishay Document 89001. This value is measured under pulsed conditions (≤40 ms) and reflects real-world performance in thermally stressed converter outputs. At 25 °C, VF is 0.533 V max, confirming strong temperature coefficient behavior ideal for high-temperature efficiency maintenance.
What packaging format does SS8P3L-E3/86A ship in?
SS8P3L-E3/86A ships in 7-inch diameter plastic tape and reel format, with a base quantity of 1500 units per reel (ordering code /86A). The tape conforms to EIA-481 standards and is compatible with standard high-speed pick-and-place equipment. Reel dimensions, orientation, and sprocket hole pitch match JEDEC TO-277A handling requirements, ensuring reliable automated assembly without modification to existing SMT lines.
How does the dual-anode configuration of SS8P3L-E3/86A improve performance?
The dual-anode configuration in SS8P3L-E3/86A reduces effective series resistance by distributing current across two parallel internal die connections, lowering total conduction loss and thermal hotspot formation. Electrically, Anode 1 and Anode 2 are internally tied and interchangeable-no sequencing or balancing circuitry is required. This architecture enables higher current density within the same TO-277A footprint versus single-anode equivalents like SB830, directly supporting the 8.0 A rating with minimal voltage drop.
