Product details
Overview
VS-ETX1506STRR-M3 from Vishay Semiconductors is a hyperfast recovery rectifier optimized for high-efficiency PFC boost stages and freewheeling applications in AC/DC SMPS and inverters. It delivers 15 A average forward current, 600 V repetitive peak reverse voltage, 18 ns typical reverse recovery time at 15 A/100 A/μs, 1.55 V forward voltage at 15 A and 150 °C, and operates up to 175 °C junction temperature.
For engineers reviewing the VS-ETX1506STRR-M3 datasheet, VS-ETX1506STRR-M3 pinout, VS-ETX1506STRR-M3 application, or VS-ETX1506STRR-M3 equivalent, this device is selected for its ultra-low Qrr (26 nC typ. at 25 °C), soft recovery behavior, low leakage (<0.02 μA at 25 °C), and rugged planar platinum-doped construction qualified to JEDEC JESD47.
Technical Context
This FRED Pt® diode employs platinum diffusion lifetime control to achieve precise trade-off between forward voltage and recovery speed. Its planar structure ensures stable trr across temperature and current, with soft recovery minimizing EMI and snubber stress.
Dynamic performance is characterized under standardized conditions: trr = 18 ns (IF = 15 A, dIF/dt = 100 A/μs, VR = 30 V, TJ = 25 °C), Qrr = 26 nC (same conditions), and IRRM = 2.7 A - enabling accurate loss modeling in hard-switched topologies like boost PFC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 400 VAC input systems with ≥2× safety margin against line transients in industrial and telecom PFC designs. |
| IF(AV) | 15 A at TC = 127 °C - enables compact heatsink sizing in continuous conduction mode (CCM) PFC stages operating near full load. |
| VF @ 15 A / 150 °C | 1.55 V - reduces conduction losses by ~25% vs. standard FRDs, directly improving system efficiency at elevated temperatures. |
| trr (typ.) | 18 ns - limits switching loss contribution during turn-off and suppresses voltage overshoot in fast-switching Si MOSFET-based PFC controllers. |
| Qrr (typ.) | 26 nC - minimizes stored charge dissipation in switching devices and snubbers, critical for maintaining efficiency at >100 kHz operation. |
| RthJC | 1.3–1.51 °C/W - allows thermal design with ≤15 W power dissipation using standard D2PAK-compatible heatsinks. |
| TJ max. | 175 °C - supports operation in high-ambient environments (e.g., enclosed server PSUs, solar inverters) without derating penalties. |
Pinout & Package
D2PAK (TO-263AB) surface-mount package with isolated thermal pad; 3-terminal single-diode configuration. Anode and cathode terminals are electrically and thermally optimized for high-current PCB mounting with minimal parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Main current entry point; bonded to internal die anode; requires low-inductance trace routing to minimize voltage spikes during commutation. |
| 2 | Cathode | Main current exit point; connected to large copper pour for thermal dissipation and low-impedance return path to ground or bus rail. |
| 3 | Thermal Pad (Exposed Die Attach) | Electrically isolated but thermally conductive base; must be soldered to PCB copper area ≥11 mm × 9.65 mm for RthJC compliance and 175 °C operation. |
Key Features
| Feature | Design Value |
|---|---|
| Platinum-doped lifetime control | Enables reproducible trr <23 ns and Qrr <30 nC across production lots and temperature, eliminating post-manufacture sorting. |
| Soft reverse recovery | di(rec)/dt-limited waveform reduces EMI generation and eliminates need for external RC snubbers in most 65–200 kHz PFC designs. |
| JEDEC JESD47 qualification | Validated for 1000+ hours HTOL, 1000-cycle temperature cycling, and HAST - ensuring reliability in 10-year industrial power supplies. |
| MSL Level 1 (245 °C peak) | Compatible with standard lead-free reflow profiles without baking or special handling, reducing manufacturing cost and risk. |
| Halogen-free & RoHS-compliant | Meets IPC-1752A Class 2 material declarations and EU Directive 2011/65/EU, supporting green product certifications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY1506TR-M3 | Same 600 V / 15 A rating but uses silicon carbide Schottky architecture; zero Qrr, VF = 1.7 V @ 15 A, TJ max = 175 °C. | Eliminates reverse recovery entirely but exhibits higher forward drop and sensitivity to voltage transients above 600 V. | Select when EMI reduction is paramount and input voltage is tightly regulated below 550 V; avoid in unregulated AC/DC front-ends with high line surges. |
| STTH1506D | 600 V / 15 A hyperfast diode with trr = 35 ns (typ.), VF = 1.85 V @ 15 A, RthJC = 1.7 °C/W, TO-220AC package. | Higher trr and VF increase switching/conduction losses; through-hole package limits high-frequency layout density. | Choose for cost-sensitive, lower-frequency (<65 kHz) designs where PCB space and thermal performance are less constrained. |
Compared with VSKY1506TR-M3 and STTH1506D, the VS-ETX1506STRR-M3 offers optimal balance of ultra-low Qrr (26 nC), moderate VF (1.55 V), and robust 175 °C operation in surface-mount D2PAK - making it the preferred choice for high-density, high-efficiency PFC stages requiring proven reliability and manufacturability.

FAQ
What is the maximum allowable case temperature for VS-ETX1506STRR-M3 at 15 A average forward current?
The maximum allowable case temperature for VS-ETX1506STRR-M3 at 15 A IF(AV) is 127 °C, as specified in the Absolute Maximum Ratings table. This value is derived from thermal modeling using RthJC = 1.3–1.51 °C/W and ensures safe operation within the 175 °C junction limit. Exceeding 127 °C case temperature risks exceeding TJ max and triggering thermal failure. The VS-ETX1506STRR-M3 datasheet Fig. 5 provides derating curves for lower currents.
Does VS-ETX1506STRR-M3 support lead-free reflow soldering?
Yes, VS-ETX1506STRR-M3 meets MSL Level 1 per J-STD-020 and is rated for a maximum lead-free reflow peak temperature of 245 °C. Its halogen-free, RoHS-compliant terminations and packaging are fully compatible with standard Pb-free SAC305 profiles. No pre-baking is required, and the device maintains parameter integrity after exposure to industry-standard reflow cycles - a key advantage confirmed in Vishay's qualification report for VS-ETX1506STRR-M3.
How does the platinum doping in VS-ETX1506STRR-M3 improve recovery consistency?
Platinum doping in VS-ETX1506STRR-M3 provides precise, uniform carrier lifetime control across the silicon die, resulting in highly repeatable trr (17–23 ns) and Qrr (26–130 nC) values across temperature and current. Unlike gold-doped or electron-irradiated diodes, platinum offers superior thermal stability - meaning VS-ETX1506STRR-M3 maintains tight recovery specs from -65 °C to 175 °C without parameter drift, critical for automotive and industrial designs.
Can VS-ETX1506STRR-M3 replace TO-220 packaged diodes in existing layouts?
No, VS-ETX1506STRR-M3 uses the D2PAK (TO-263AB) surface-mount package with a 3-pin footprint and exposed thermal pad, which is mechanically and thermally incompatible with through-hole TO-220 footprints. Direct replacement would require PCB redesign, including new land patterns, stencil apertures, and thermal copper pour. For drop-in alternatives, consider Vishay's TO-220 variant VS-ETX1506-M3 - not VS-ETX1506STRR-M3.
What is the typical junction capacitance of VS-ETX1506STRR-M3 at 600 V reverse bias?
The typical junction capacitance (CT) of VS-ETX1506STRR-M3 at VR = 600 V is 12 pF, as specified in the Electrical Specifications table. This low CT value minimizes displacement current during high dv/dt switching events, reducing gate drive loading and EMI in high-frequency PFC circuits. Measured at 1 MHz, CT remains stable across temperature due to the planar structure - a verified characteristic of the VS-ETX1506STRR-M3 device family.
