Vishay General Semiconductor - Diodes Division V15P6HM3_A/H

Overview

V15P6HM3_A/H from Vishay General Semiconductor is a high-current-density Trench MOS Barrier Schottky (TMBS®) rectifier in SMPC (TO-277A) package, rated for 15 A average forward current, 60 V reverse voltage, and 220 A surge capability, with ultra-low VF of 0.33 V at 5 A and 125 °C - optimized for DC/DC converters and polarity protection in space-constrained power stages.

For engineers reviewing the V15P6HM3_A/H datasheet, V15P6HM3_A/H pinout, V15P6HM3_A/H application, or V15P6HM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification status (denoted by HM3 suffix), 1.1 mm profile, J-STD-020 MSL Level 1 rating, and thermal resistance of 4 °C/W junction-to-mount on aluminum PCBs.

Technical Context

The V15P6HM3_A/H employs trench MOS Schottky technology to achieve low forward voltage and high efficiency, eliminating minority-carrier storage delay typical of PN junction rectifiers. Its single-anode dual-cathode configuration (pins 1 & 2 anode, pin 3 cathode) supports high-frequency switching up to MHz-range operation without reverse recovery loss.

Thermally, it is designed for direct mounting on aluminum PCBs (R_θJM = 4 °C/W) or standard FR-4 (R_θJA = 75 °C/W), with maximum junction temperature of 150 °C and dV/dt rating of 10,000 V/μs - enabling robust performance in noisy automotive and industrial environments.

FAQ

What is the meaning of the "HM3" suffix in V15P6HM3_A/H?

The "HM3" suffix in V15P6HM3_A/H indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" denotes the AEC-Q101 grade, while "M3" specifies the material and plating standard meeting JESD 201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow compatibility. This makes V15P6HM3_A/H suitable for automotive under-hood applications where reliability and process compatibility are critical.

Does V15P6HM3_A/H have a dual-anode configuration, and how is it used in layout?

Yes, V15P6HM3_A/H features a dual-anode configuration (pins 1 and 2) internally connected to a common anode node, with pin 3 as the shared cathode. In PCB layout, both anode pads should be routed to the same high-current input net, while the cathode connects to the output return. This structure improves current sharing and thermal spreading across the copper area, especially when mounted on aluminum substrates - a key design advantage of the V15P6HM3_A/H.

What is the thermal resistance RθJM for V15P6HM3_A/H, and under what conditions is it measured?

The thermal resistance RθJM for V15P6HM3_A/H is 4 °C/W, measured when mounted on a 30 mm × 30 mm aluminum PCB per the datasheet note. This value reflects junction-to-mount interface performance and enables accurate thermal modeling for forced-air or conduction-cooled designs. It is significantly lower than the RθJA of 75 °C/W (free air), confirming that V15P6HM3_A/H achieves optimal thermal performance only when properly mounted on thermally conductive substrates - a critical implementation detail for the V15P6HM3_A/H.

Is V15P6HM3_A/H suitable for use in synchronous rectification topologies?

No, V15P6HM3_A/H is a unidirectional Schottky rectifier and not controllable - it cannot replace a MOSFET in synchronous rectification. It functions as a passive freewheeling or output rectifier. For synchronous designs, external gate drivers and logic-controlled MOSFETs are required. However, the V15P6HM3_A/H remains ideal as a robust, low-VF alternative in non-synchronous buck, boost, or flyback outputs where simplicity and reliability are prioritized over peak efficiency.

What does the "_A/H" suffix indicate in the full part number V15P6HM3_A/H?

The "_A/H" suffix in V15P6HM3_A/H specifies packaging and reel configuration: "A" denotes revision level A per Vishay's internal change control, and "H" identifies the preferred package code for 7-inch plastic tape-and-reel delivery with 1500 units per reel. This matches the ordering information in Document 87716 and confirms the V15P6HM3_A/H is supplied in industry-standard automated assembly format compatible with pick-and-place equipment.
