Product details
Overview
V10P45-M3/86A from Vishay General Semiconductor is a high-current-density Trench MOS Barrier Schottky (TMBS®) rectifier in SMPC (TO-277A) package, rated for 45 V reverse voltage, 10 A average forward current, and 180 A non-repetitive surge. It delivers ultra-low forward voltage (0.41 V at 10 A, 25 °C) and operates up to 150 °C junction temperature, enabling high-efficiency DC/DC converters in space-constrained power supplies.
For engineers reviewing the V10P45-M3/86A datasheet, V10P45-M3/86A pinout, V10P45-M3/86A application, or V10P45-M3/86A equivalent, key selection criteria include its low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, JESD 201 Class 2 whisker resistance, halogen-free RoHS-compliant construction, and suitability for automated SMT placement in automotive-grade and industrial power designs.
Technical Context
This device uses trench MOS Schottky technology to achieve lower VF and higher current density than planar Schottky diodes. Its single-anode dual-cathode configuration (Anode 1 & 2 tied internally) supports high-current freewheeling paths with minimized conduction loss.
Thermal performance is optimized for surface-mount use: RθJA = 75 °C/W (free air), RθJM = 4 °C/W (on 30 mm × 30 mm Al PCB), enabling stable operation under sustained 10 A loads without forced cooling in compact layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1045C-Y | Same VRRM (45 V), same IF(AV) (10 A), but VF = 0.52 V @ 10 A (25 °C); TO-277 package, not SMPC | Higher conduction loss; requires larger thermal pad due to higher RθJA (90 °C/W) | Select when legacy TO-277 footprint compatibility is required and 0.11 V higher VF is acceptable |
| SS1040B-TP | 40 V VRRM, 10 A IF(AV), VF = 0.50 V @ 10 A; SMA package, 2-pin, lower surge rating (100 A) | Not suitable for 45 V systems or high-surge environments; limited thermal performance (RθJA ≈ 120 °C/W) | Select only for cost-sensitive, low-power (<5 A), non-automotive applications where 5 V margin is acceptable |
Compared with STPS1045C-Y and SS1040B-TP, the V10P45-M3/86A provides superior thermal management (RθJM = 4 °C/W), lower VF, and automotive-grade reliability-making it preferred for high-efficiency, high-reliability 12–24 V power rails where board space and thermal headroom are constrained.

FAQ
What is the maximum junction temperature rating for the V10P45-M3/86A?
The V10P45-M3/86A has a maximum junction temperature (TJ) of +150 °C, validated per JEDEC standards. This rating allows continuous operation in high-ambient environments such as under-hood automotive locations or sealed industrial enclosures. Derating curves in the datasheet confirm usable current capacity down to -40 °C ambient, ensuring robustness across full industrial temperature ranges. The V10P45-M3/86A must be mounted per recommended pad layout to maintain thermal integrity at this limit.
Is the V10P45-M3/86A qualified for automotive applications?
The base V10P45-M3/86A is commercial-grade and RoHS-compliant but not AEC-Q101 qualified. For automotive use, Vishay offers the V10P45HM3_A/H variant with "HM3" suffix and underscored revision code (e.g., "A"), which carries full AEC-Q101 qualification. The V10P45-M3/86A itself meets MSL Level 1 and JESD 201 Class 2 whisker requirements-key prerequisites-but lacks the extended temperature cycling and lifetime testing required for automotive grade. Always specify HM3 variants for automotive designs.
What does the "/86A" suffix indicate in V10P45-M3/86A?
The "/86A" suffix in V10P45-M3/86A identifies the packaging configuration: 7-inch diameter plastic tape-and-reel, with 1500 units per reel. "86A" is Vishay's preferred package code for this format; "87A" denotes the 13-inch reel option (6500 units). Both share identical electrical and thermal specifications. The "M3" denotes halogen-free, RoHS-compliant matte tin plating meeting JESD 201 Class 2 whisker resistance-critical for long-term reliability in automated assembly.
How does the dual-anode configuration (Pins 1 & 2) of the V10P45-M3/86A improve performance?
The dual-anode design (Pins 1 and 2) in the V10P45-M3/86A reduces effective series resistance and distributes current across two parallel bond wires and copper traces. This lowers localized heating, improves surge current handling (180 A IFSM), and enhances thermal uniformity under high DC load. Unlike single-anode equivalents, the V10P45-M3/86A avoids current crowding at one terminal-directly supporting stable 10 A operation in compact layouts without additional thermal vias or copper pours.
Can the V10P45-M3/86A replace standard Schottky diodes like SB1040 in existing designs?
The V10P45-M3/86A can replace diodes such as SB1040 in many applications-but only after verifying layout compatibility: SB1040 uses DO-214AA (SMB), while V10P45-M3/86A uses SMPC (TO-277A), differing in pad dimensions and thermal pad requirements. Electrically, the V10P45-M3/86A offers lower VF (0.41 V vs. ~0.55 V) and higher IFSM (180 A vs. 120 A), improving efficiency and ruggedness. However, the V10P45-M3/86A requires updated stencil and reflow profile due to its MSL Level 1 rating and low-profile geometry.
