Product details
Overview
V20PWM63HM3/I from Vishay General Semiconductor is a high-current-density Trench MOS Barrier Schottky (TMBS®) rectifier in SlimDPAK (TO-252AE) package, rated for 60 V reverse voltage and 20 A average forward current, with ultra-low 0.55 V forward voltage at 20 A and 125 °C junction temperature - deployed in automotive-grade DC/DC converters and polarity protection circuits.
For engineers reviewing the V20PWM63HM3/I datasheet, V20PWM63HM3/I pinout, V20PWM63HM3/I application, or V20PWM63HM3/I equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, 65 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on FR4 PCBs with defined copper pad layouts.
Technical Context
This device implements trench MOS Schottky barrier technology to achieve lower forward voltage and higher current density than planar Schottky diodes. Its single-anode/cathode configuration supports unidirectional conduction in low-voltage, high-frequency switching paths where fast recovery and minimal conduction loss are critical.
Thermal performance is defined by RθJA = 65 °C/W (free air, recommended copper pad) and RθJM = 1.8 °C/W (infinite heatsink), enabling operation up to 175 °C junction temperature. It meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker testing requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V20PWM63-M3/I | Same die, identical electrical specs, but not AEC-Q101 qualified; halogen-free and RoHS-compliant. | Targeted at industrial/commercial power supplies where automotive qualification is not required. | Select when AEC-Q101 is unnecessary and cost sensitivity favors non-automotive grade. |
| SS20P6 | Planar Schottky, 60 V/20 A, VF = 0.65 V @ 20 A/125 °C; RθJA = 75 °C/W; no AEC-Q101 qualification. | Suitable for non-automotive, lower-efficiency DC/DC where thermal margin allows higher VF. | Choose only if footprint compatibility exists and 0.1 V higher VF is acceptable for system efficiency targets. |
Compared with V20PWM63HM3/I, the V20PWM63-M3/I offers identical performance without automotive qualification, while SS20P6 trades 0.1 V higher forward drop and inferior thermal resistance for broader commercial availability - making V20PWM63HM3/I optimal where AEC-Q101 compliance and lowest conduction loss are mandatory.

FAQ
What is the AEC-Q101 qualification status of V20PWM63HM3/I?
V20PWM63HM3/I is fully AEC-Q101 qualified per the Vishay datasheet revision dated 08-Oct-2021. This includes stress testing for temperature cycling, humidity bias, high-temperature operating life, and mechanical shock - confirming suitability for automotive under-hood applications. The HM3 suffix explicitly denotes AEC-Q101 compliance, unlike the M3 variant.
Does V20PWM63HM3/I support lead-free reflow assembly?
Yes, V20PWM63HM3/I meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 260 °C, making it compatible with standard lead-free soldering processes. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 2 whisker testing.
What is the thermal resistance of V20PWM63HM3/I when mounted on a standard PCB?
V20PWM63HM3/I has a typical RθJA of 65 °C/W when mounted on the recommended FR4 copper pad area per the datasheet layout. This value assumes natural convection cooling and is used to calculate junction temperature rise: TJ = TA + (PD × RθJA). For higher power, the exposed cathode tab must be soldered to a thermal pad.
How does the forward voltage of V20PWM63HM3/I compare at different temperatures?
V20PWM63HM3/I exhibits a negative temperature coefficient: VF drops from 0.61 V at 25 °C to 0.55 V at 125 °C (at 20 A). At 5 A, VF is 0.39 V at 125 °C - confirming improved conduction efficiency at elevated operating temperatures typical in automotive environments.
Is V20PWM63HM3/I pin-compatible with other SlimDPAK Schottky rectifiers?
V20PWM63HM3/I uses the standard SlimDPAK (TO-252AE) outline with 3 terminals (anode, cathode, heatsink tab), matching mechanical footprint and solder pad layout of industry-standard TO-252AE devices. However, electrical characteristics - especially VF, IFSM, and thermal resistance - differ significantly from non-TMBS® alternatives like SS20P6.
