Product details
Overview
V8PAM103S-M3/H from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in SMPA (DO-221BC) package, rated for 100 V repetitive peak reverse voltage and 8.0 A average forward current at 175 °C junction temperature, with 0.63 V forward voltage at 8.0 A and 125 °C - optimized for high-efficiency DC/DC converters and automotive polarity protection.
For engineers reviewing the V8PAM103S-M3/H datasheet, V8PAM103S-M3/H pinout, V8PAM103S-M3/H application, or V8PAM103S-M3/H equivalent, key selection criteria include its low-profile 0.95 mm height, AEC-Q101 qualification (via HM3 variant), MSL Level 1 rating, and thermal resistance of 100 °C/W (junction-to-ambient on FR4).
Technical Context
This TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and reduced switching losses versus planar Schottky diodes. Its single-anode/cathode configuration supports unidirectional conduction in high-frequency power conversion stages where fast recovery and minimal reverse recovery charge are critical.
The device operates across -40 °C to +175 °C junction temperature range and is qualified per JESD22-B102 for solderability and JESD201 Class 2 for tin whisker resistance. Thermal performance relies on copper pad area optimization - RθJA drops from 100 °C/W (2 oz FR4) to ~50 °C/W with larger pads, while RθJM is 5 °C/W when mounted on aluminum PCB.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V8PAM103SHM3/H | AEC-Q101 qualified; identical electrical specs and package; HM3 suffix denotes automotive qualification | Required for automotive production programs needing PPAP and long-term supply assurance | Select V8PAM103SHM3/H when automotive qualification is mandatory; otherwise V8PAM103S-M3/H suffices for commercial use |
| SS8P10L-M3/84A | Same 100 V / 8 A rating, DO-221BC package, but planar Schottky; VF = 0.75 V @ 8 A / 125 °C (vs. 0.63 V) | Higher conduction loss limits use in thermally constrained designs; not AEC-Q101 qualified | Choose SS8P10L-M3/84A only if cost sensitivity outweighs efficiency and qualification needs |
Compared with V8PAM103S-M3/H, the HM3 variant adds automotive qualification without electrical trade-offs, while SS8P10L-M3/84A offers lower cost at the expense of 0.12 V higher forward drop and no AEC-Q101 validation - making V8PAM103S-M3/H optimal for high-efficiency commercial power stages requiring robust thermal performance.

FAQ
What is the maximum junction temperature rating for the V8PAM103S-M3/H?
The V8PAM103S-M3/H has a maximum junction temperature (TJ max.) of +175 °C, enabling reliable operation in under-hood automotive environments and sealed industrial enclosures. This rating is validated per JEDEC JESD22-A108 and supported by thermal characterization data showing stable RθJA and RθJM values across the full temperature range. The V8PAM103S-M3/H maintains specified electrical performance up to this limit without derating when mounted on appropriate copper area.
Is the V8PAM103S-M3/H AEC-Q101 qualified?
No - the V8PAM103S-M3/H is the commercial-grade version. AEC-Q101 qualification applies only to the V8PAM103SHM3/H variant (HM3 suffix). Both share identical electrical specifications and SMPA package, but only the HM3 version undergoes the full AEC-Q101 stress test sequence including HTGB, HTRB, and temperature cycling. The V8PAM103S-M3/H remains suitable for non-automotive applications requiring high reliability and thermal robustness.
What does the "-M3/H" suffix indicate in V8PAM103S-M3/H?
The "-M3" denotes Vishay's standard halogen-free, RoHS-compliant tape-and-reel packaging, while "/H" specifies the reel size: 7-inch diameter plastic tape and reel containing 3500 units. This packaging format ensures compatibility with high-speed pick-and-place equipment and meets J-STD-020 moisture sensitivity Level 1 requirements - no baking required prior to reflow. The V8PAM103S-M3/H is fully compatible with lead-free soldering profiles peaking at 260 °C.
How does the V8PAM103S-M3/H compare to planar Schottky rectifiers in terms of forward voltage?
The V8PAM103S-M3/H achieves 0.63 V forward voltage at 8.0 A and 125 °C, which is approximately 0.12 V lower than comparable planar Schottky rectifiers like the SS8P10L-M3/84A under identical conditions. This reduction stems from its trench MOS barrier structure, which lowers series resistance and improves carrier injection efficiency. As a result, the V8PAM103S-M3/H delivers measurably lower conduction losses - critical for maintaining efficiency in high-current, high-temperature DC/DC converters.
What is the thermal resistance junction-to-ambient (RθJA) for the V8PAM103S-M3/H?
The V8PAM103S-M3/H has a typical RθJA of 100 °C/W when mounted on a 2 oz copper pad on FR4 PCB, per JEDEC 51-7 test conditions. This value assumes a recommended 3 cm × 3 cm copper area. With increased pad area or aluminum substrate, RθJA can improve significantly - down to ~50 °C/W on 6 cm² copper or ~5 °C/W (RθJM) on aluminum PCB. Proper thermal layout is essential to sustain 8.0 A IF(AV) without exceeding 175 °C junction temperature.
