Product details
Overview
VS-15ETH03-1-M3 from Vishay Semiconductors is a hyperfast recovery rectifier diode rated for 300 V repetitive peak reverse voltage and 15 A average forward current, featuring 40 ns typical reverse recovery time (trr), 0.85 V forward voltage at 15 A and 125 °C, and 175 °C maximum junction temperature. It serves as an output rectifier in high-frequency SMPS and DC/DC converters where low switching loss and thermal robustness are critical.
For engineers reviewing the VS-15ETH03-1-M3 datasheet, VS-15ETH03-1-M3 pinout, VS-15ETH03-1-M3 application, or VS-15ETH03-1-M3 equivalent, this device is selected for high-efficiency power conversion stages requiring fast recovery, low VF, and rugged TO-262AA packaging with validated thermal resistance of 1.02 °C/W (junction-to-case).
Technical Context
This device employs a planar structure with platinum doping for lifetime control, enabling optimized trade-off between forward voltage drop and reverse recovery performance. Its hyperfast trr (32–45 ns across temperature) and low Qrr (38–137 nC) minimize snubber dissipation and switching losses in hard-switched topologies.
The TO-262AA package provides mechanical compatibility with TO-220 footprints while supporting higher thermal performance than standard TO-220, with RthJC = 1.02 °C/W and case-to-heatsink thermal resistance of 0.2 °C/W under greased mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (VRRM) | 300 V - Withstands up to 300 V reverse blocking without breakdown, suitable for 24–48 V output DC/DC and UPS systems with 300 V bus margin. |
| IF(AV) | 15 A at TC = 142 °C - Sustains continuous 15 A conduction when mounted on heatsink maintaining case temperature ≤142 °C. |
| VF @ 15 A / 125 °C | 0.85 V (typ.) - Reduces forward conduction loss to ~12.75 W per device, critical for efficiency in high-current output stages. |
| trr (typ.) | 40 ns at 25 °C, 45 ns at 125 °C - Enables operation at >100 kHz switching frequencies with minimal reverse recovery tail and EMI generation. |
| Qrr | 137 nC at 125 °C - Low stored charge reduces peak recovery current (IRRM = 6.1 A) and associated stress on MOSFETs and snubbers. |
| RthJC | 1.02 °C/W (typ.) - Allows direct thermal path from junction to heatsink, supporting compact thermal design with <2 °C rise per watt. |
| TJ max. | 175 °C - Enables reliable operation in high-ambient industrial environments without derating below full current rating. |
Pinout & Package
VS-15ETH03-1-M3 is housed in TO-262AA (JEDEC variant of TO-220 with isolated tab), a through-hole package with three leads and electrically isolated metal tab for direct heatsink mounting. The package supports 6.0–12 kgf·cm mounting torque and weighs 2.0 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Primary current entry point; connects to switching node in flyback or forward converters. |
| 2 (Cathode) | Cathode connection | Output rail connection; carries full load current to +VOUT bus with minimal VF drop. |
| 3 (Anode) | Second anode terminal | Redundant anode lead for dual-die configuration - enables parallel conduction path and lower effective series resistance. |
| Metal Tab | Electrically isolated thermal pad | Provides low-thermal-resistance path to heatsink (RthCS = 0.2 °C/W) without electrical connection to any terminal. |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: Anti-parallel diode across IGBTs to handle reactive current during commutation. Use Value: Low Qrr (137 nC @ 125 °C) limits IRRM to 6.1 A, reducing IGBT turn-off voltage overshoot and snubber capacitor stress. |
Use Scenario: Snubber diode in 24–72 V brushed DC chopper drives for material handling equipment. IC Role / Device Role / Timing Role: Clamp diode absorbing inductive kickback energy during MOSFET turn-off. Use Value: Hyperfast 40 ns trr ensures clean energy transfer into RC snubber without oscillation, extending MOSFET lifetime by reducing dv/dt-induced gate stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15ETH03S-M3 | D2PAK (TO-263AB) surface-mount package; identical electrical specs but 1.25 °C/W RthJC and 0.35 °C/W RthCS. | Suitable for automated SMT assembly; requires PCB copper area for thermal management instead of external heatsink. | Select VS-15ETH03S-M3 for space-constrained board-level designs where reflow compatibility and footprint density outweigh discrete heatsink flexibility. |
| ON Semiconductor MUR1530CT | TO-220 package; 300 V/15 A; trr = 60 ns (typ.), VF = 1.15 V @ 15 A/125 °C; no platinum doping. | Higher VF and slower recovery increase conduction + switching loss by ~22% at 200 kHz; not rated for 175 °C TJ. | Choose MUR1530CT only for cost-sensitive, lower-frequency (<100 kHz), non-derated ambient applications where thermal headroom exceeds 25 °C. |
Compared with VS-15ETH03S-M3, VS-15ETH03-1-M3 offers superior thermal interface via TO-262AA's isolated tab and lower RthJC, while versus MUR1530CT it delivers measurable efficiency gain and extended high-temperature reliability - making it optimal for thermally demanding, high-frequency industrial power stages.

FAQ
What is the maximum junction temperature rating for VS-15ETH03-1-M3?
The VS-15ETH03-1-M3 has a maximum junction temperature (TJ max.) of 175 °C, verified per Vishay's datasheet revision 22-Nov-2021 (Doc. #96230). This allows continuous operation in high-ambient industrial environments without derating, provided thermal design maintains junction temperature below this limit. The device's 175 °C rating is enabled by platinum-doped silicon and robust planar construction.
How does VS-15ETH03-1-M3 differ from VS-15ETH03S-M3?
The VS-15ETH03-1-M3 uses a TO-262AA through-hole package with electrically isolated metal tab, whereas VS-15ETH03S-M3 uses D2PAK (TO-263AB) surface-mount packaging. Both share identical electrical characteristics - 300 V VRRM, 15 A IF(AV), 40 ns trr, and 0.85 V VF at 15 A/125 °C - but differ in thermal resistance: VS-15ETH03-1-M3 achieves 1.02 °C/W RthJC vs. 1.25 °C/W for VS-15ETH03S-M3.
What is the reverse recovery charge (Qrr) of VS-15ETH03-1-M3 at 125 °C?
At TJ = 125 °C, the VS-15ETH03-1-M3 exhibits a typical reverse recovery charge (Qrr) of 137 nC, as specified in the "Dynamic Recovery Characteristics" table of its official datasheet (Doc. #96230). This low Qrr directly reduces peak reverse recovery current (IRRM = 6.1 A) and associated switching losses in high-frequency converters.
Is VS-15ETH03-1-M3 compatible with lead-free reflow soldering?
Yes, VS-15ETH03-1-M3 meets MSL Level 1 per J-STD-020 with a maximum lead-free reflow peak temperature of 245 °C, confirmed in its Vishay datasheet. The -M3 suffix denotes halogen-free, RoHS-compliant construction with lead (Pb)-free terminations, making it fully compatible with standard Pb-free assembly processes without preconditioning.
What is the thermal resistance from junction to case (RthJC) for VS-15ETH03-1-M3?
The VS-15ETH03-1-M3 has a typical junction-to-case thermal resistance (RthJC) of 1.02 °C/W, as published in the "Thermal-Mechanical Specifications" section of its Vishay datasheet (Doc. #96230). This value is measured under standard test conditions and enables accurate thermal modeling for heatsink sizing in high-power rectification applications.
