Product details
Overview
VS-30WQ10FNTRHM3 from Vishay Semiconductors is a surface-mount Schottky rectifier optimized for high-frequency switching power supplies and reverse battery protection. It delivers 3.5 A average forward current, 100 V reverse voltage rating, and 0.63 V forward voltage drop at 3 A and 125 °C - enabling low conduction loss in compact automotive and industrial DC/DC converters.
For engineers reviewing the VS-30WQ10FNTRHM3 datasheet, VS-30WQ10FNTRHM3 pinout, VS-30WQ10FNTRHM3 application, or VS-30WQ10FNTRHM3 equivalent, key selection criteria include its AEC-Q101 qualification, D-PAK (TO-252AA) thermal performance (RthJC = 4.7 °C/W), 5 mJ non-repetitive avalanche energy, and halogen-free RoHS-compliant M3 termination.
Technical Context
This Schottky rectifier employs a single-die construction with guard ring technology to enhance ruggedness and long-term reliability under repetitive surge stress. Its low forward slope resistance (30.89 mΩ) and typical junction capacitance (92 pF at 5 V) support efficient high-frequency operation in synchronous rectification and freewheeling roles.
The device operates across –40 °C to +150 °C junction temperature range and meets JESD201 Class 2 whisker test and MSL Level 1 (260 °C peak reflow), making it suitable for automotive under-hood and industrial control applications requiring robust thermal and mechanical stability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3L100S | 3 A IF(AV), 100 V VRRM, TO-277 package (smaller footprint, no thermal pad) | Limited thermal dissipation capability (RthJC ≈ 12 °C/W); unsuitable for >2 A continuous operation without forced cooling | Select when board space is critical and power dissipation remains below 1.2 W |
| ON Semiconductor SB3100 | 3 A IF(AV), 100 V VRRM, DO-214AB package; VF = 0.85 V @ 3 A, 25 °C | Higher forward voltage increases conduction loss by ~35 % at 125 °C; not AEC-Q101 qualified | Select for cost-sensitive consumer applications where automotive qualification is unnecessary |
Compared with STPS3L100S and SB3100, the VS-30WQ10FNTRHM3 offers superior thermal management via its D-PAK thermal pad, lower VF at elevated temperature, and automotive-grade reliability - making it the preferred choice for thermally demanding, safety-critical 3.5 A rectification tasks.

FAQ
What is the maximum junction temperature rating for the VS-30WQ10FNTRHM3?
The VS-30WQ10FNTRHM3 has a maximum junction temperature (TJ) of +150 °C, validated across its full operating range from –40 °C to +150 °C. This rating is supported by its AEC-Q101 qualification and thermal design - including RthJC = 4.7 °C/W - enabling reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 100 °C.
Is the VS-30WQ10FNTRHM3 suitable for automotive applications?
Yes, the VS-30WQ10FNTRHM3 is AEC-Q101 qualified and meets JESD201 Class 2 whisker testing and MSL Level 1 reflow standards. Its 100 V VRRM, 3.5 A IF(AV), and 5 mJ avalanche energy make it appropriate for reverse battery protection, engine control unit power rails, and ADAS subsystems where robustness against transients and thermal cycling is required.
What does the "M3" suffix indicate in VS-30WQ10FNTRHM3?
The "M3" suffix in VS-30WQ10FNTRHM3 denotes halogen-free, RoHS-compliant construction with lead (Pb)-free terminations, per JEDEC J-STD-609A. It confirms compliance with environmental regulations and supports lead-free reflow soldering profiles up to 260 °C peak, without compromising solder joint integrity or long-term reliability.
How does the D-PAK (TO-252AA) package of the VS-30WQ10FNTRHM3 improve thermal performance?
The D-PAK package of the VS-30WQ10FNTRHM3 features an exposed thermal pad (Pin 2) that directly interfaces with the PCB copper pour or heatsink. With RthJC = 4.7 °C/W, this design enables >3 W of power dissipation using standard 2 oz. copper and thermal vias - significantly outperforming DO-214AB or SOD-123 packages in sustained high-current operation.
What is the forward voltage drop of the VS-30WQ10FNTRHM3 at 3 A and 125 °C?
The VS-30WQ10FNTRHM3 exhibits a forward voltage drop (VF) of 0.63 V at 3 A and 125 °C, as specified in the Vishay datasheet (Document #94731). This low VF value - combined with its 30.89 mΩ forward slope resistance - ensures minimal conduction loss and stable thermal behavior under high-temperature, high-load conditions typical in automotive and industrial power systems.
