Product details
Overview
V10PM103HM3/H from Vishay General Semiconductor is a high-current-density Trench MOS Barrier Schottky (TMBS®) rectifier in SMPC (TO-277A) package, rated for 100 V reverse voltage and 10 A average forward current at 125 °C, with ultra-low forward voltage of 0.54 V at 10 A/125 °C - optimized for DC/DC converters, freewheeling diodes, and polarity protection in automotive and industrial power supplies.
For engineers reviewing the V10PM103HM3/H datasheet, V10PM103HM3/H pinout, V10PM103HM3/H application, or V10PM103HM3/H equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, 1.1 mm profile, 75 °C/W junction-to-ambient thermal resistance, and low VF performance under high-temperature, high-current conditions.
Technical Context
This device uses trench MOS Schottky technology to achieve lower forward voltage and higher efficiency than planar Schottky or standard PN rectifiers. Its single-diode configuration supports unidirectional conduction with cathode-common mounting on aluminum PCBs, leveraging RθJM = 4 °C/W for enhanced thermal management.
The V10PM103HM3/H operates across -40 °C to +175 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. It delivers 180 A non-repetitive surge capability and exhibits 1730 pF junction capacitance at 4.0 V/1 MHz - critical for high-frequency switching noise and EMI behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in DC/DC output rectification and flyback clamp circuits |
| IF(AV) | 10 A at 125 °C - continuous forward current rating on 30 mm × 30 mm Al PCB; enables compact high-power density designs |
| VF @ 10 A / 125 °C | 0.54 V - low conduction loss reduces heat generation and improves system efficiency in 12 V–48 V bus applications |
| IFSM | 180 A - peak surge current handling for transient load dumps or startup inductance energy dissipation |
| TJ max | +175 °C - extended thermal capability supports under-hood automotive environments and sealed industrial enclosures |
| RθJA | 75 °C/W - thermal resistance in free-air condition; informs heatsinking requirements when mounted on standard FR4 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V10PM103-M3/H | Commercial-grade version; same electrical specs but not AEC-Q101 qualified; RθJA identical; no automotive qualification testing | Preferred for cost-sensitive industrial or consumer power supplies where automotive reliability is not mandated | Select V10PM103-M3/H when AEC-Q101 is unnecessary and BOM cost optimization is prioritized |
| STPS10H100CG-TR | 100 V / 10 A Schottky; VF = 0.69 V @ 10 A / 125 °C; TO-277 package; not AEC-Q101 qualified; higher VF increases conduction loss by ~28 % | Used in general-purpose industrial SMPS; lacks automotive qualification and low-VF advantage of TMBS® architecture | Choose STPS10H100CG-TR only if Vishay supply constraints exist; expect higher thermal load and reduced efficiency vs. V10PM103HM3/H |
Compared with V10PM103-M3/H and STPS10H100CG-TR, the V10PM103HM3/H delivers superior thermal performance (175 °C TJ max), lower forward voltage, and verified automotive qualification - making it the optimal choice for high-reliability, high-efficiency 10 A rectification where qualification and efficiency are jointly critical.

FAQ
What is the maximum junction temperature rating for the V10PM103HM3/H?
The V10PM103HM3/H has a maximum junction temperature (TJ) of +175 °C, validated per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and thermally demanding industrial enclosures. The device maintains specified electrical characteristics up to this temperature, with forward voltage increasing predictably per datasheet curves. Thermal design must ensure dPD/dTJ < 1/RθJA to avoid thermal runaway.
Is the V10PM103HM3/H pin-compatible with other TO-277A Schottky rectifiers?
The V10PM103HM3/H uses the standard SMPC (TO-277A) footprint with three terminals: two anodes (pins 1 and 2) and one cathode (pin 3). It shares mechanical compatibility with other TO-277A devices like STPS10H100CG-TR and SB10100, but pin function alignment must be verified per datasheet - some variants use different pinouts (e.g., cathode-anode-anode). Always confirm terminal mapping before PCB layout reuse.
Does the V10PM103HM3/H meet automotive qualification standards?
Yes, the V10PM103HM3/H is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3". This qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per AEC-Q101 Rev D. The device is intended for automotive powertrain, chassis, and body electronics where robustness against thermal and electrical stress is required.
What is the forward voltage of the V10PM103HM3/H at 5 A and 25 °C?
The V10PM103HM3/H exhibits a typical forward voltage (VF) of 0.53 V at 5 A and 25 °C, with a maximum of 0.61 V under those conditions. This low VF is enabled by its trench MOS barrier Schottky construction and contributes directly to reduced conduction losses in low-voltage, high-current applications such as 12 V output rectification.
How does the thermal resistance of the V10PM103HM3/H compare between junction-to-mount and junction-to-ambient?
The V10PM103HM3/H has RθJM = 4 °C/W when mounted on a 30 mm × 30 mm aluminum PCB, and RθJA = 75 °C/W in free air on recommended pad areas. This 18.75× difference highlights the critical impact of thermal interface design: using a metal-core PCB reduces thermal impedance dramatically, enabling higher sustained current without exceeding TJ max. Layout must prioritize cathode pad thermal coupling.
