Product details
Overview
VS-30WQ10FNTRRHM3 from Vishay Semiconductors is a surface-mount Schottky rectifier optimized for low forward voltage drop and high-frequency switching in power conversion circuits. It delivers 3.5 A average forward current at 100 V reverse voltage, with 0.63 V VF at 3 A and 125 °C junction temperature, and is AEC-Q101 qualified for automotive-grade reliability in battery protection and DC/DC converter applications.
For engineers reviewing the VS-30WQ10FNTRRHM3 datasheet, VS-30WQ10FNTRRHM3 pinout, VS-30WQ10FNTRRHM3 application, or VS-30WQ10FNTRRHM3 equivalent, key selection criteria include its D-PAK (TO-252AA) thermal performance (RthJC = 4.7 °C/W), 5 mJ non-repetitive avalanche energy rating, and 10,000 V/μs dV/dt capability - all critical for robust freewheeling and reverse polarity protection designs.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring technology to enhance ruggedness and long-term reliability under thermal cycling and surge stress. Its low forward slope resistance (30.89 mΩ) and low junction capacitance (92 pF at 5 V) support efficient high-frequency operation in synchronous rectification and switching power supplies.
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 halogen-free, RoHS-compliant, lead-free terminations (M3 suffix) and AEC-Q101 qualification confirm suitability for automotive electronics requiring stringent process and reliability validation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 3.5 A average forward current at 135 °C case temperature - enables compact heatsink design in space-constrained 12–48 V DC/DC converters |
| VRRM | 100 V maximum repetitive reverse voltage - supports input stages of automotive 24 V systems and industrial 48 V power rails |
| VF @ 3 A, 125 °C | 0.63 V forward voltage - reduces conduction loss by ~35% vs. standard PN diodes, improving efficiency in battery charging paths |
| RthJC | 4.7 °C/W junction-to-case thermal resistance - allows direct mounting to PCB copper pour for passive thermal management without external heatsinks |
| EAS | 5.0 mJ non-repetitive avalanche energy - provides margin against inductive switching transients in motor drive freewheeling circuits |
| dV/dt | 10,000 V/μs maximum voltage rate of change - ensures stable operation during fast-switching transitions in SMPS and inverters |
| CT @ 5 V | 92 pF typical junction capacitance - minimizes switching losses and EMI generation in >100 kHz power topologies |
Pinout & Package
D-PAK (TO-252AA) package with exposed thermal pad on the base for enhanced heat dissipation; footprint compatible with JEDEC TO-252AA outline (Document #95519), dimensions: 6.09 × 6.54 × 2.29 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pins 1 & 4) | Forward current entry point | Internally connected pins provide parallel current path and lower effective series resistance; must be routed to high-current source node |
| Cathode (Pin 3) | Forward current exit / reverse blocking terminal | Single high-current output pin tied to internal die cathode; requires wide copper pour for thermal and current handling |
| Base (Pin 2) | Thermal pad / mechanical ground | Exposed metal tab electrically isolated but thermally coupled to die; must be soldered to large PCB copper area for RthJC = 4.7 °C/W performance |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents edge breakdown under high dv/dt and high-temperature bias, extending lifetime in automotive load dump conditions |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing - eliminates need for additional qualification in Tier-1 BOMs |
| Halogen-free & RoHS-compliant (M3) | Meets global environmental regulations without compromising solderability or thermal performance of SnAgCu terminations |
| MSL Level 1 (260 °C peak) | Enables standard SMT reflow without baking or special handling - reduces manufacturing cost and yield risk |
| Low IRM (4.9 mA @ 125 °C) | Minimizes leakage-induced standby power loss in always-on battery systems such as telematics and ADAS modules |

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 VF = 0.72 V @ 3 A/125 °C; TO-277 package (no thermal pad) | Lacks exposed thermal pad → higher RthJA; unsuitable for high-power-density automotive modules | Select when board-level thermal management is handled externally and footprint flexibility is prioritized over thermal performance |
| ON Semi SB3100 | 3 A IF(AV), 100 V VRRM, VF = 0.75 V @ 3 A/125 °C; D-PAK package but not AEC-Q101 qualified | No automotive qualification - requires full requalification for automotive BOM inclusion | Select for industrial or consumer applications where AEC-Q101 is not mandated and cost is primary driver |
Compared with STPS3L100S and SB3100, the VS-30WQ10FNTRRHM3 uniquely combines AEC-Q101 qualification, lowest VF (0.63 V), and D-PAK thermal pad integration - making it the only option among the three qualified for under-hood automotive power conversion without derating or redesign.

FAQ
What is the maximum junction temperature rating for the VS-30WQ10FNTRRHM3?
The VS-30WQ10FNTRRHM3 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 its AEC-Q101 qualification and thermal design - including 4.7 °C/W RthJC - enabling reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 85 °C. The VS-30WQ10FNTRRHM3 maintains specified electrical parameters up to this limit.
Is the VS-30WQ10FNTRRHM3 pin-compatible with other D-PAK Schottky rectifiers?
The VS-30WQ10FNTRRHM3 uses the standard JEDEC TO-252AA (D-PAK) outline with confirmed pin configuration: Anode on Pins 1 & 4, Cathode on Pin 3, and Base (thermal pad) on Pin 2. While footprint-compatible with most D-PAK rectifiers, true pin compatibility requires matching internal connectivity - which is confirmed only for Vishay's VS-30WQ10FNxHM3 variants. Cross-manufacturer substitution requires verification of anode/cathode pin mapping and thermal pad isolation.
Does the VS-30WQ10FNTRRHM3 support lead-free reflow assembly?
Yes, the VS-30WQ10FNTRRHM3 features M3-suffix terminations: halogen-free, RoHS-compliant, and lead (Pb)-free with SnAgCu solder finish. It is rated for MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C - fully compatible with standard lead-free SMT reflow profiles without pre-baking or special handling requirements.
What is the avalanche energy rating of the VS-30WQ10FNTRRHM3, and how is it applied in circuit design?
The VS-30WQ10FNTRRHM3 is rated for 5.0 mJ non-repetitive avalanche energy (EAS) at TJ = 25 °C with IAS = 1 A and L = 10 mH. This parameter defines safe single-pulse inductive energy absorption during switch turn-off events - critical for freewheeling in relay drivers, solenoid controls, and flyback converters. Designers use this value to size snubbers or verify margin against worst-case inductive kick without device failure.
How does the guard ring feature improve reliability of the VS-30WQ10FNTRRHM3 in automotive applications?
The guard ring in the VS-30WQ10FNTRRHM3 mitigates edge breakdown under high dv/dt and elevated temperature bias - a common failure mode during automotive load dump or cold-crank transients. By controlling electric field distribution at the silicon periphery, it enhances long-term ruggedness and extends operational lifetime in harsh environments, directly supporting AEC-Q101 stress test compliance including HTRB and temperature cycling.
