Vishay General Semiconductor - Diodes Division V10P22HM3/H

Overview

V10P22HM3/H from Vishay General Semiconductor is a high-current-density Trench MOS Barrier Schottky (TMBS®) rectifier in SMPC (TO-277A) package, rated for 200 V repetitive peak reverse voltage and 10 A average forward current, with ultra-low 0.68 V forward voltage at 10 A and 175 °C maximum junction temperature - deployed in DC/DC converters, freewheeling paths, and polarity protection circuits.

For engineers reviewing the V10P22HM3/H datasheet, V10P22HM3/H pinout, V10P22HM3/H application, or V10P22HM3/H equivalent, key selection criteria include its AEC-Q101 qualification status (HM3 suffix), low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and thermal resistance of 4 °C/W junction-to-mount on recommended PCB layout.

Technical Context

This device implements trench MOS Schottky technology to achieve lower forward voltage and higher current density than planar Schottky diodes. Its single-anode–dual-cathode configuration (Anode 1 & 2 tied internally) enables high-reliability unidirectional conduction with minimized switching losses in high-frequency operation.

Thermal design is constrained by R_θJM = 4 °C/W (junction-to-mount) and R_θJA = 80 °C/W (junction-to-ambient on 30 mm × 30 mm Al PCB), requiring careful pad layout per JEDEC TO-277A footprint. It supports automated placement and meets JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards.

FAQ

What is the maximum junction temperature rating for the V10P22HM3/H?

The V10P22HM3/H has a maximum junction temperature (T_J) of +175 °C, validated across its full operating range and confirmed in Vishay's datasheet revision 19-Apr-2023. This rating enables reliable operation in under-hood automotive environments and high-power-density industrial converters where ambient temperatures exceed 125 °C. The V10P22HM3/H maintains specified electrical characteristics up to this limit when mounted per recommended thermal pad layout.

Is the V10P22HM3/H pin-compatible with the V10P22-M3/H?

Yes, the V10P22HM3/H and V10P22-M3/H share identical SMPC (TO-277A) package dimensions, pin assignment (Anode 1, Anode 2, Cathode), and mechanical footprint. Both parts use the same 3-terminal configuration and mounting pad layout per JEDEC TO-277A. The only functional difference is AEC-Q101 qualification - present in V10P22HM3/H but not in V10P22-M3/H - making them drop-in replacements where automotive qualification is not required.

What does the "HM3" suffix indicate in V10P22HM3/H?

The "HM3" suffix in V10P22HM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering documentation, "HM3" identifies the automotive-grade variant - distinct from "M3" (commercial grade) - and confirms compliance with JESD 201 Class 2 whisker resistance, J-STD-020 MSL Level 1, and full AEC-Q101 stress testing. The "/H" indicates 7-inch tape-and-reel packaging with 1500 units per reel.

What is the typical forward voltage of the V10P22HM3/H at 5 A and 125 °C?

The typical forward voltage (V_F) of the V10P22HM3/H is 0.60 V at 5 A and 125 °C, as specified in the Electrical Characteristics table of Vishay document 87002. This value reflects reduced voltage drop at elevated temperature due to the TMBS® trench structure's improved carrier transport, supporting stable performance in thermally demanding applications like engine-control DC/DC converters where junction temperatures routinely reach 125 °C.

Does the V10P22HM3/H require special PCB layout considerations for thermal performance?

Yes, the V10P22HM3/H requires adherence to Vishay's recommended mounting pad layout for optimal thermal performance: a minimum 30 mm × 30 mm copper area on aluminum PCB achieves R_θJA = 80 °C/W, while the 4 °C/W R_θJM rating assumes direct thermal coupling to a heatsink or metal-core PCB. Deviation from the specified SMPC (TO-277A) footprint - including pad size, copper thickness (2 oz.), and thermal via placement - degrades junction-to-mount thermal resistance and risks exceeding 175 °C T_J under full 10 A load.
