Product details
Overview
V15P103-M3/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 repetitive peak reverse voltage and 15 A average forward current at 125 °C, with ultra-low forward voltage of 0.54 V at 15 A - optimized for DC/DC converters and freewheeling in automotive and industrial power supplies.
For engineers reviewing the V15P103-M3/H datasheet, V15P103-M3/H pinout, V15P103-M3/H application, or V15P103-M3/H equivalent, key selection criteria include its 0.37 V VF at 5 A/125 °C, AEC-Q101 qualification option (HM3 suffix), MSL Level 1 rating, 75 °C/W junction-to-ambient thermal resistance, and compatibility with 260 °C lead-free reflow.
Technical Context
This TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and higher current density than planar Schottky diodes. Its single-cathode, dual-anode configuration (pins 1 & 2 = anode, pin 3 = cathode) enables low-loss unidirectional conduction with minimal reverse recovery charge.
Designed for surface-mount operation on aluminum PCBs, it delivers stable performance across -40 °C to +150 °C junction temperature range. Thermal resistance RθJM is 4 °C/W when mounted on 30 mm × 30 mm aluminum PCB, supporting high-efficiency thermal management in space-constrained power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input rails up to 80 V DC with 20 % safety margin in buck converters and polarity protection circuits |
| IF(AV) | 15 A at 125 °C - enables continuous conduction mode operation in 50–100 W DC/DC stages without forced air cooling |
| VF @ 15 A / 125 °C | 0.54 V - reduces conduction loss to ≤8.1 W per device, critical for thermally limited board areas |
| IFSM | 220 A (10 ms half-sine) - withstands inrush and short-circuit surge currents in motor drive freewheeling paths |
| RθJA | 75 °C/W - requires ≥30 mm × 30 mm copper pad area on FR4 for safe 15 A operation at 25 °C ambient |
| Junction Cap. (CJ) | 2350 pF @ 4 V - limits high-frequency switching noise in >100 kHz converters; impacts EMI filter sizing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V15P103HM3/H | AEC-Q101 qualified; identical electrical specs but certified for automotive use; same SMPC package and pinout | Required for automotive OEM designs; not needed for commercial-grade industrial power supplies | Select V15P103HM3/H only when automotive qualification documentation (PPAP, test reports) is mandatory |
| SS15100L-TP | 15 A/100 V Schottky; VF = 0.58 V @ 15 A/125 °C; TO-277 package (mechanically identical but non-TMBS® construction) | Higher VF increases conduction loss by ~0.6 W at full load; suitable where cost sensitivity outweighs efficiency targets | Choose SS15100L-TP for cost-driven consumer power adapters where 0.04 V VF penalty is acceptable |
Compared with V15P103HM3/H, the V15P103-M3/H offers identical performance without automotive certification overhead; versus SS15100L-TP, it delivers measurable efficiency gain via trench MOS architecture - critical for thermally constrained 15 A applications.

FAQ
What is the maximum junction temperature rating for the V15P103-M3/H?
The V15P103-M3/H has a maximum junction temperature (TJ max.) of +150 °C, verified per JEDEC standards. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves confirm 15 A IF(AV) capability at 125 °C case temperature, with thermal resistance RθJA = 75 °C/W on standard FR4 PCBs. The V15P103-M3/H must be mounted on recommended pad areas to maintain this limit.
Is the V15P103-M3/H pin-compatible with the AEC-Q101 qualified V15P103HM3/H?
Yes, the V15P103-M3/H is mechanically and electrically pin-compatible with V15P103HM3/H - both use identical SMPC (TO-277A) packaging, dual-anode/single-cathode pinout (pins 1 & 2 = anode, pin 3 = cathode), and share all primary electrical ratings. The only difference is automotive qualification: V15P103HM3/H carries AEC-Q101 certification, while V15P103-M3/H is commercial grade. No PCB changes are required when upgrading to the HM3 variant.
What is the forward voltage of the V15P103-M3/H at 5 A and 125 °C?
The V15P103-M3/H exhibits a typical forward voltage (VF) of 0.37 V at 5 A and 125 °C, as specified in the Vishay datasheet (Document Number: 98457). This ultra-low VF is enabled by trench MOS barrier Schottky technology and directly reduces conduction losses in high-duty-cycle applications such as DC/DC converter outputs. At room temperature, VF is 0.45 V under the same conditions.
Does the V15P103-M3/H meet lead-free reflow requirements?
Yes, the V15P103-M3/H is fully compatible with lead-free reflow soldering processes, rated for a maximum peak temperature of 260 °C per J-STD-020. It meets MSL Level 1 moisture sensitivity classification, meaning it can be stored indefinitely at ambient conditions without baking prior to assembly. Matte tin-plated terminals ensure robust wetting and intermetallic formation during reflow.
What is the reverse leakage current of the V15P103-M3/H at 100 V and 125 °C?
At VR = 100 V and TJ = 125 °C, the V15P103-M3/H has a maximum reverse leakage current (IR) of 70 mA, with a typical value of 23 mA. This parameter is critical for low-power standby modes and polarity protection circuits where leakage must be minimized. The V15P103-M3/H maintains significantly lower IR than conventional fast recovery diodes under identical conditions, improving system efficiency.
