Product details
Overview
V15PM103-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 reverse voltage and 15 A average forward current at 125 °C, with ultra-low forward voltage of 0.56 V at 15 A - optimized for DC/DC converters, freewheeling diodes, and polarity protection in automotive and industrial power supplies.
For engineers reviewing the V15PM103-M3/H datasheet, V15PM103-M3/H pinout, V15PM103-M3/H application, or V15PM103-M3/H equivalent, key selection criteria include its 0.42 V VF at 5 A/125 °C, AEC-Q101 qualification (HM3 variant), 175 °C max junction temperature, MSL Level 1 rating, and low-profile 1.1 mm height - critical for thermally constrained, high-efficiency 12–48 V systems.
Technical Context
This TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and higher current density than planar Schottky diodes, enabling reduced conduction losses in high-frequency switching topologies. Its single-cathode, dual-anode configuration (pins 1 & 2 = anode, pin 3 = cathode) supports high-current PCB mounting with low thermal resistance (RθJM = 4 °C/W on aluminum substrate).
The device operates across -40 °C to +175 °C junction temperature range and delivers 220 A non-repetitive surge capability. Its 2350 pF junction capacitance at 4 V/1 MHz and low leakage (<0.38 mA at 100 V/25 °C) support stable performance in fast-switching DC/DC stages without excessive ringing or EMI.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V15PM103HM3/H | AEC-Q101 qualified; identical electrical specs; HM3 suffix denotes automotive qualification | Required for automotive-grade designs needing PPAP documentation and extended temperature validation | Select HM3 variant when automotive compliance (e.g., ISO/TS 16949, AEC-Q101 test reports) is mandatory |
| SS15100L-TP | 15 A/100 V Schottky; VF = 0.65 V @ 15 A/25 °C; TO-277 package; no AEC-Q101 or MSL Level 1 rating | Suitable for commercial-grade 48 V systems where automotive qualification and reflow compatibility are not required | Choose SS15100L-TP only for cost-sensitive, non-automotive applications with relaxed thermal and reliability requirements |
Compared with V15PM103-M3/H, the HM3 variant adds automotive qualification without electrical trade-offs, while SS15100L-TP offers similar ratings but lacks MSL Level 1 and AEC-Q101 - making V15PM103-M3/H the optimal choice for high-reliability, high-volume SMT production in industrial and automotive-adjacent systems.

FAQ
What is the maximum junction temperature rating for the V15PM103-M3/H?
The V15PM103-M3/H has a maximum junction temperature (TJ max.) of +175 °C, verified per Vishay's datasheet revision 09-Jan-2023. This rating allows reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105 °C. Thermal design must maintain dPD/dTJ < 1/RθJA to avoid thermal runaway.
Is the V15PM103-M3/H pin-compatible with the V15PM103HM3/H?
Yes, the V15PM103-M3/H and V15PM103HM3/H share identical SMPC (TO-277A) package dimensions, pinout (anode-anode-cathode), and solder pad layout. The HM3 variant adds AEC-Q101 qualification but retains full mechanical and electrical compatibility - enabling drop-in replacement where automotive qualification is later required.
What does the "-M3/H" suffix indicate in V15PM103-M3/H?
The "-M3" suffix denotes halogen-free, RoHS-compliant, commercial-grade construction per JESD201 Class 2 whisker testing. The "/H" indicates packaging in 7-inch plastic tape-and-reel format with 1500 units per reel. This ordering code ensures traceable, SMT-ready delivery aligned with IPC-7351 standards.
Can the V15PM103-M3/H be used in synchronous rectification topologies?
No - the V15PM103-M3/H is a passive Schottky rectifier and cannot replace a MOSFET in synchronous rectification. It serves as a freewheeling or output rectifier in non-synchronous buck, flyback, or forward converters. For synchronous designs, use a logic-level N-channel MOSFET controlled by a dedicated gate driver.
What is the thermal resistance from junction to mount (RθJM) for V15PM103-M3/H?
The V15PM103-M3/H has a typical RθJM of 4 °C/W when mounted on a 30 mm × 30 mm aluminum PCB, per datasheet Figure 1 and Thermal Characteristics table. This value assumes direct thermal interface between the cathode pad and metal substrate - critical for achieving rated 15 A current in high-power-density applications.
