Product details
Overview
SS8P3L-M3/87A from Vishay General Semiconductor is a high-current-density surface-mount Schottky barrier rectifier in SMPC (TO-277A) package, rated for 30 V repetitive peak reverse voltage, 8.0 A average forward current, and 0.472 V forward voltage at 8.0 A. It delivers low thermal resistance (RθJL = 3.5 °C/W), operates up to 150 °C junction temperature, and is used in DC/DC converters and polarity protection circuits.
For engineers reviewing the SS8P3L-M3/87A datasheet, SS8P3L-M3/87A pinout, SS8P3L-M3/87A application, or SS8P3L-M3/87A equivalent, key selection criteria include its 30 V VRRM, 150 A IFSM, 20 mJ non-repetitive avalanche energy, 330 pF junction capacitance, and AEC-Q101-qualified variants with HM3 suffix.
Technical Context
The SS8P3L-M3/87A implements a single-anode dual-cathode Schottky structure in SMPC (TO-277A) package, enabling high-current conduction with minimal forward loss. Its low RθJL of 3.5 °C/W and 1.1 mm profile support compact, thermally efficient PCB layouts in space-constrained power stages.
Designed for high-frequency switching applications, it exhibits 330 pF junction capacitance at 4.0 V/1 MHz and maintains stable reverse leakage (<35 mA at 125 °C, VR = 30 V), ensuring reliable freewheeling and reverse-biased blocking in DC/DC topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS8P3LHM3_A/I | AEC-Q101 qualified; identical electrical specs and SMPC package | Required for automotive-grade designs requiring qualification evidence | Select SS8P3LHM3_A/I when automotive reliability certification is mandatory |
| ON Semiconductor SB830 | Same 30 V VRRM, 8 A IF(AV), but TO-277 package (not TO-277A); RθJA = 60 °C/W vs. 3.5 °C/W RθJL | Higher thermal impedance limits power density in compact layouts | Choose SS8P3L-M3/87A over SB830 where board-level thermal performance is critical |
Compared with SS8P3LHM3_A/I, SS8P3L-M3/87A offers identical performance but lacks AEC-Q101 documentation; compared with SB830, it provides superior thermal coupling via RθJL = 3.5 °C/W, enabling higher sustained current in thermally constrained designs.

FAQ
What is the maximum junction temperature rating for SS8P3L-M3/87A?
The SS8P3L-M3/87A has a maximum operating junction temperature of +150 °C, verified per Vishay Document Number 89001. This rating enables reliable operation in high-temperature environments such as enclosed power supplies and automotive under-hood locations when proper thermal design is implemented. The device's RθJL of 3.5 °C/W supports effective heat dissipation to the PCB.
Does SS8P3L-M3/87A have AEC-Q101 qualification?
No, SS8P3L-M3/87A is the commercial-grade version with M3 suffix. AEC-Q101 qualification is only available in the HM3-suffixed variants such as SS8P3LHM3_A/I. The SS8P3L-M3/87A meets JESD 201 Class 2 whisker test and RoHS/halogen-free requirements but does not carry automotive qualification documentation.
What is the marking code for SS8P3L-M3/87A on the device body?
The SS8P3L-M3/87A is marked with "S83" on its top surface, as specified in the Vishay SS8P2L/SS8P3L datasheet (Document Number 89001). This marking distinguishes it from the SS8P2L variant, which uses "S82", and confirms its 30 V VRRM rating.
What package type does SS8P3L-M3/87A use, and is it compatible with automated assembly?
SS8P3L-M3/87A uses the SMPC (TO-277A) package - a 3-terminal surface-mount case with 1.1 mm typical height. It is explicitly designed for automated placement and meets J-STD-020 MSL Level 1 with 260 °C peak reflow profile, making it fully compatible with standard SMT lines.
How does the dual-anode structure of SS8P3L-M3/87A affect circuit layout?
The SS8P3L-M3/87A features two anode terminals (Anode 1 and Anode 2) sharing one cathode (K), allowing symmetrical current splitting and reduced current density per bond wire. In layout, both anodes must be routed to the same input net, while the cathode connects to the common return path - this configuration lowers localized heating and improves thermal uniformity versus single-anode equivalents.
