Product details
Overview
VS-ETH1506STRR-M3 from Vishay Semiconductors is a hyperfast recovery rectifier optimized for high-efficiency PFC boost stages in AC/DC SMPS and inverter freewheeling applications. It delivers 15 A average forward current, 600 V repetitive peak reverse voltage, 1.25 V forward voltage at 15 A and 150 °C, 21 ns typical reverse recovery time at 1.0 A, and operates up to 175 °C junction temperature.
For engineers reviewing the VS-ETH1506STRR-M3 datasheet, VS-ETH1506STRR-M3 pinout, VS-ETH1506STRR-M3 application, or VS-ETH1506STRR-M3 equivalent, this device is selected for low switching loss, soft recovery behavior, and rugged thermal performance in high-frequency power conversion designs requiring precise charge control and minimal EMI generation.
Technical Context
This FRED Pt® diode uses platinum-doped lifetime control and planar junction architecture to achieve hyperfast, soft reverse recovery with low Qrr (60 nC typ. at 25 °C) and low IRRM (3.9 A typ.). Its stored charge is tightly controlled to minimize snubber stress and switching element over-dissipation.
The device is rated for 175 °C operation and qualified per JEDEC JESD47; it meets MSL Level 1 per J-STD-020 with 245 °C lead-free reflow peak. Thermal resistance from junction-to-case is 1.3–1.51 °C/W, enabling high-power density mounting on heatsinks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1506D | 600 V, 15 A, trr = 35 ns (typ.), VF = 1.7 V @ 15 A, 150 °C; TO-220AC package. | Higher trr and VF increase switching and conduction losses; requires larger heatsink due to higher RthJA. | Acceptable where cost sensitivity outweighs efficiency targets; not suitable for >80 kHz PFC or compact thermal layouts. |
| IXYS MUR1560CT | 600 V, 15 A dual common-cathode; trr = 35 ns (typ.), VF = 1.85 V @ 15 A; TO-220AB package. | Dual configuration enables half-wave bridge use but lacks single-diode optimization; higher Qrr (110 nC) increases snubber stress. | Only appropriate for non-critical freewheeling or legacy designs; not recommended for new PFC implementations targeting <150 mW standby loss. |
Compared with STTH1506D and IXYS MUR1560CT, the VS-ETH1506STRR-M3 offers superior dynamic performance (21 ns trr, 60 nC Qrr) and thermal capability (175 °C, 1.3 °C/W RthJC), making it the preferred choice for high-efficiency, high-power-density PFC and inverter designs where switching loss and thermal headroom are critical.

FAQ
What is the maximum junction temperature rating for the VS-ETH1506STRR-M3?
The VS-ETH1506STRR-M3 is rated for a maximum junction temperature of 175 °C, verified per JEDEC JESD47 qualification testing. This allows sustained operation in high-ambient environments such as enclosed telecom rectifiers or industrial inverters without derating at full current when properly heatsinked. The device maintains specified VF and trr performance up to this limit.
Does the VS-ETH1506STRR-M3 have a halogen-free and RoHS-compliant construction?
Yes, the VS-ETH1506STRR-M3 carries the "-M3" suffix, indicating full compliance with RoHS Directive 2011/65/EU and halogen-free material requirements per IEC 61249-2-21. Its terminations are lead (Pb)-free, and all packaging materials meet Vishay's Material Category 1 standards as defined in document 99912.
What is the reverse recovery charge (Qrr) of the VS-ETH1506STRR-M3 at 125 °C?
At TJ = 125 °C, the VS-ETH1506STRR-M3 exhibits a typical reverse recovery charge (Qrr) of 240 nC under test conditions of IF = 15 A, dIF/dt = 100 A/μs, and VR = 30 V. This value is confirmed in the Electrical Specifications table on page 2 of Vishay document 96331 and directly impacts snubber sizing and switching loss calculations.
Is the VS-ETH1506STRR-M3 pin-compatible with the VS-ETH1506S-M3?
Yes, the VS-ETH1506STRR-M3 shares identical D2PAK (TO-263AB) package dimensions, pinout (anode-pin 1, cathode-pin 2, thermal pad-pin 3), and solder footprint with the VS-ETH1506S-M3. Both use right-oriented tape-and-reel packaging (TRR), differing only in reel orientation-not electrical or mechanical form factor.
What thermal resistance values apply to the VS-ETH1506STRR-M3 in a typical PCB mount?
The VS-ETH1506STRR-M3 has a junction-to-case thermal resistance (RthJC) of 1.3–1.51 °C/W, measured from die to the exposed thermal pad. When mounted on a 1-in² 2-oz copper pad with thermal vias, typical junction-to-ambient resistance drops to ~35–45 °C/W-significantly lower than the 70 °C/W value listed for socket-mount reference conditions.
