Vishay General Semiconductor - Diodes Division V15K170C-M3/H

Overview

V15K170C-M3/H from Vishay General Semiconductor is a dual common-cathode Trench MOS Barrier Schottky (TMBS®) rectifier in FlatPAK 5×6 package, rated for 170 V reverse voltage and 2 × 7.5 A average forward current per diode, with ultra-low 0.66 V forward voltage at 7.5 A and 125 °C junction temperature-optimized for high-efficiency DC/DC converters and freewheeling in automotive and industrial power supplies.

For engineers reviewing the V15K170C-M3/H datasheet, V15K170C-M3/H pinout, V15K170C-M3/H application, or V15K170C-M3/H equivalent, key selection criteria include its dual common-cathode configuration, 130 A surge rating, AEC-Q101 qualification eligibility (via HM3 suffix), thermal resistance of 2.5 °C/W junction-to-mount, and halogen-free RoHS-compliant construction.

Technical Context

This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous rectification or dual-path freewheeling in compact board space. Its trench MOS barrier structure achieves lower VF and higher current density than planar Schottky diodes, with junction capacitance of 460 pF at 4.0 V and 1 MHz.

Thermal performance is defined by RθJM = 2.5 °C/W (junction-to-mount) under infinite heatsink conditions and RθJA = 75 °C/W in free air on recommended copper pad area. The device operates across –40 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 reflow profile (260 °C peak).

FAQ

What is the maximum junction temperature rating for the V15K170C-M3/H?

The V15K170C-M3/H has a maximum operating junction temperature (TJ max.) of +150 °C, verified per datasheet revision 15-Dec-2025. This rating allows reliable operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures. Derating curves in Figure 1 confirm usable current capacity down to –40 °C ambient, and thermal resistance values (RθJM = 2.5 °C/W) support stable thermal design when mounted to appropriate copper area or heatsink.

Is the V15K170C-M3/H pin-compatible with the V15K170CHM3_A/H variant?

Yes-the V15K170C-M3/H and V15K170CHM3_A/H share identical FlatPAK 5×6 mechanical dimensions, pinout, and electrical specifications; only the marking and qualification status differ. The HM3_A variant adds AEC-Q101 qualification and revision-coded marking ("A"), but both use the same 8-pin layout with pins 1–2 (Anode 1), 3–4 (Anode 2), and 5–8 (Common Cathode). No PCB layout change is required when upgrading to the automotive-qualified version.

What does the "-M3/H" suffix indicate in V15K170C-M3/H?

The "-M3/H" suffix denotes Vishay's standard halogen-free, RoHS-compliant packaging: "M3" specifies matte tin plating and JESD 201 Class 2 whisker resistance, while "/H" indicates 7-inch plastic tape-and-reel packaging with 1500 units per reel. This matches the ordering information table in Document Number 98154 and confirms compliance with environmental standards without automotive qualification-distinct from the "HM3" suffix used for AEC-Q101 versions.

Can the V15K170C-M3/H be used in a single-diode configuration?

Yes-the V15K170C-M3/H contains two electrically isolated Schottky diodes sharing a common cathode; either anode (pins 1–2 or 3–4) can be used independently while leaving the other anode unconnected. However, doing so forfeits the thermal and layout advantages of dual utilization. The device remains fully functional with one anode unused, maintaining its 170 V VRRM and 7.5 A IF(AV) rating per active diode.

What is the typical forward voltage of the V15K170C-M3/H at room temperature and 5 A?

The typical forward voltage (VF) of the V15K170C-M3/H is 0.77 V at IF = 5 A and TJ = 25 °C, as specified in the Electrical Characteristics table (Document Number 98154, page 2). This value is measured per diode under pulsed conditions (300 μs, 1 % duty cycle) and reflects the low-loss performance enabled by Vishay's Trench MOS Barrier Schottky technology-significantly lower than conventional silicon rectifiers in the same voltage class.
