Product details
Overview
VS-30WQ10FNTRLHM3 from Vishay Semiconductors is a surface-mount Schottky rectifier optimized for low forward voltage drop (0.63 V at 3 A, 125 °C), 100 V reverse voltage rating, and 3.5 A average forward current handling in D-PAK (TO-252AA) package. It serves as a freewheeling or reverse-battery protection diode in automotive-grade DC/DC converters and switching power supplies.
For engineers reviewing the VS-30WQ10FNTRLHM3 datasheet, VS-30WQ10FNTRLHM3 pinout, VS-30WQ10FNTRLHM3 application, or VS-30WQ10FNTRLHM3 equivalent, key selection criteria include its AEC-Q101 qualification, 5 mJ non-repetitive avalanche energy rating, 4.7 °C/W junction-to-case thermal resistance, and halogen-free RoHS-compliant M3 termination finish.
Technical Context
This Schottky rectifier uses 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 high dV/dt capability (10,000 V/μs) support stable operation in high-frequency switching topologies up to several hundred kHz.
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). Its 92 pF junction capacitance at 5 V and 5.0 nH series inductance are characterized for accurate EMI modeling in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 3.5 A average forward current - supports continuous conduction mode in 25–50 W DC/DC converters without heatsink at TC ≤ 135 °C |
| VRRM | 100 V maximum repetitive reverse voltage - suitable for 48 V automotive bus and 36 V industrial supply rail protection |
| VF @ 3 A, 125 °C | 0.63 V - reduces conduction loss by ~35 % vs. standard PN diodes, lowering thermal load in sealed enclosures |
| RthJC | 4.7 °C/W - enables direct mounting to copper pour or small heatsink for thermal management in space-constrained designs |
| EAS | 5.0 mJ - withstands inductive turn-off transients in motor drive flyback paths without avalanche failure |
| IRM @ 125 °C | 4.9 mA - ensures minimal leakage-induced standby power loss in battery-backed systems |
| dV/dt | 10,000 V/μs - prevents false triggering in fast-switching half-bridge configurations with steep edge rates |
Pinout & Package
D-PAK (TO-252AA) package with exposed thermal pad on underside; 3-terminal configuration optimized for high-current surface-mount assembly and thermal dissipation via PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1 & 4) | Forward current entry point | Internally connected pins provide parallel current path and lower effective bond wire inductance |
| Cathode (Pin 3) | Forward current exit / reverse blocking terminal | Primary high-current output node; connects to ground or low-side switch return path |
| Base / Thermal Pad (Pin 2) | Thermal interface and mechanical anchor | Electrically isolated metal tab - must be soldered to large PCB copper pour for RthJC compliance |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents edge breakdown under high dv/dt and high-temperature reverse bias, extending lifetime in automotive transients |
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control units and ADAS power stages |
| Halogen-free, Pb-free M3 finish | Complies with RoHS Directive 2011/65/EU and JEDEC JS709C; eliminates brominated flame retardants in molding compound |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak without moisture sensitivity concerns |
| Low CT (92 pF @ 5 V) | Minimizes capacitive coupling noise in high-side gate drive bootstrap circuits and synchronous rectifier timing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3L100S | Same 100 V VRRM and 3 A IF(AV), but TO-277 package (no thermal pad); RthJC = 12.5 °C/W | Limited to lower-power (<15 W) applications due to higher thermal resistance; unsuitable for AEC-Q101 automotive use | Select only for cost-sensitive consumer power adapters where board space allows larger footprint and thermal margin is ample |
| ON Semi MBR3100T3G | 3 A IF(AV), 100 V VRRM, DPAK package, but VF = 0.82 V @ 3 A, 125 °C; not AEC-Q101 qualified | Higher conduction loss increases junction temperature rise by ~12 °C at full load; no automotive qualification documentation | Acceptable for industrial UPS or lighting drivers where automotive reliability and 0.63 V VF are not required |
Compared with STPS3L100S and MBR3100T3G, the VS-30WQ10FNTRLHM3 delivers superior thermal performance (4.7 vs. ≥12.5 °C/W), lower forward drop, and formal AEC-Q101 validation-making it the only choice for thermally constrained, automotive-grade 3.5 A rectification.

FAQ
What is the maximum junction temperature rating for the VS-30WQ10FNTRLHM3?
The VS-30WQ10FNTRLHM3 has a maximum junction temperature (TJ max.) of 150 °C, validated across its full operating range from -40 °C to +150 °C. This rating is supported by thermal characterization data in Figure 4 of the official datasheet (Document Number 94731), and enables reliable operation in under-hood automotive environments and sealed industrial enclosures without active cooling.
Is the VS-30WQ10FNTRLHM3 pin-compatible with other D-PAK Schottky rectifiers?
The VS-30WQ10FNTRLHM3 uses the standard D-PAK (TO-252AA) outline with Anode–Cathode–Thermal Pad pin assignment (Pins 1&4–3–2), matching JEDEC MO-246AA. While mechanical footprint is identical to other D-PAK rectifiers like MBR3100T3G, electrical differences-including VF, IRM, and EAS-require verification before substitution. No official pin-to-pin replacement claim is made by Vishay for this part.
Does the VS-30WQ10FNTRLHM3 support lead-free reflow soldering?
Yes, the VS-30WQ10FNTRLHM3 carries the "M3" suffix indicating halogen-free, RoHS-compliant, and lead (Pb)-free terminations. It is rated for MSL Level 1 per J-STD-020 and qualified for peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free SMT assembly processes without preconditioning.
What does the "TRL" in VS-30WQ10FNTRLHM3 signify?
The "TRL" in VS-30WQ10FNTRLHM3 denotes tape-and-reel packaging with left-oriented orientation (as defined in Vishay's ordering guide, Document Number 94731, page 5). This configuration ensures consistent component placement direction during automated pick-and-place assembly, reducing misalignment risk in high-speed SMT lines.
How is the VS-30WQ10FNTRLHM3 different from the VS-30WQ10FNHM3 variant?
The VS-30WQ10FNTRLHM3 differs from VS-30WQ10FNHM3 solely in packaging: "TRL" indicates 3000-piece tape-and-reel (left-oriented), while "HM3" denotes antistatic plastic tube (75 pcs). All electrical, thermal, and reliability specifications-including AEC-Q101 qualification, VF, RthJC, and EAS-are identical between both variants per Vishay's ordering information table.
