Product details
Overview
VS-ETU1506STRR-M3 from Vishay Semiconductors is an ultrafast recovery silicon rectifier optimized for discontinuous conduction mode (DCM) power factor correction (PFC), delivering 15 A average forward current, 600 V repetitive peak reverse voltage, and 24 ns typical reverse recovery time at 1 A/100 A/μs - deployed in high-efficiency AC/DC SMPS up to 400 W.
For engineers reviewing the VS-ETU1506STRR-M3 datasheet, VS-ETU1506STRR-M3 pinout, VS-ETU1506STRR-M3 application, or VS-ETU1506STRR-M3 equivalent, key selection criteria include soft-switching recovery behavior, 175 °C junction temperature rating, low 1.1 V forward voltage at 15 A/150 °C, and D2PAK (TO-263AB) package compatibility with thermal management in compact power adapters and desktop PC supplies.
Technical Context
This device implements FRED Pt® (Fast Recovery Epitaxial Diode) technology with soft reverse recovery characteristics, minimizing stored charge (Qrr = 107 nC typ. at 25 °C) and peak recovery current (IRRM = 5 A typ.) to reduce switching losses and snubber stress in PFC boost stages.
It operates as a single-anode, single-cathode unidirectional rectifier with no internal series or parallel die configuration - validated for use as both PFC output diode and freewheeling diode in flyback and LLC topologies where low conduction loss and fast turn-off are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks full-line transients in universal-input 85–265 VAC SMPS without derating |
| IF(AV) | 15 A at TC = 143 °C - supports continuous conduction in high-power laptop/TV adapters |
| VF | 1.1 V at 15 A / 150 °C - reduces conduction loss by ~15% vs. standard FRDs in thermally constrained layouts |
| trr | 24 ns typ. at 1 A / 100 A/μs - enables >100 kHz PFC operation with minimal EMI generation |
| TJ(max) | 175 °C - allows sustained operation under high ambient conditions in enclosed enclosures |
| RthJC | 1.3 °C/W typ. - enables 25 W dissipation with ≤32.5 °C case-to-junction rise at 15 A DC |
| Qrr | 107 nC typ. at 25 °C - lowers diode-induced switching loss in hard-switched boost converters |
Pinout & Package
D2PAK (TO-263AB) surface-mount package with exposed thermal pad; 3-terminal configuration: Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = N/C (no connection). Mounting requires soldering the thermal pad to a copper pour for RthJC compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Main current entry point; connects to PFC inductor node or switch drain in boost topology |
| 2 | Cathode | Main current exit point; ties to bulk capacitor positive rail or output filter inductor |
| 3 | N/C | No internal connection; must remain unconnected or grounded only if PCB layout demands mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | 24 ns trr with low IRRM and Qrr minimizes voltage overshoot and EMI during turn-off |
| Low VF at high TJ | 1.1 V at 15 A / 150 °C maintains efficiency in thermally saturated PFC stages |
| 175 °C rated junction | Enables reliable operation in sealed consumer power supplies without forced air cooling |
| JEDEC JESD47 qualified | Validated for 1000+ thermal cycles and 1000 hrs HTOL - suitable for industrial-grade BOMs |
| Halogen-free, RoHS, Pb-free | M3 suffix confirms full compliance with IPC/JEDEC J-STD-609 Class 1 moisture sensitivity and environmental mandates |
Applications
| Laptop AC Adaptor | Desktop PC Power Supply |
|---|---|
Use Scenario: 90–240 VAC input, 65–120 W output, active PFC stage operating in DCM. IC Role / Device Role / Timing Role: Primary PFC output rectifier handling 15 A average current at 65–100 kHz switching frequency. Use Value: Low Qrr and soft recovery reduce MOSFET voltage spikes and snubber losses, improving overall efficiency by ≥0.5% at full load. | Use Scenario: ATX-style 250–400 W PSU with interleaved or single-stage boost PFC. IC Role / Device Role / Timing Role: High-current freewheeling diode in secondary-side synchronous rectification or PFC output stage. Use Value: 175 °C TJ(max) and 1.3 °C/W RthJC allow direct mounting to heatsink without thermal derating in space-constrained chassis. |
| Flat Panel TV Power Board | Printer AC/DC Module |
Use Scenario: 120–240 W integrated power board with integrated PFC + LLC half-bridge. IC Role / Device Role / Timing Role: Output rectifier in PFC boost stage, subjected to high dI/dt (>200 A/μs) during zero-crossing transitions. Use Value: 36 ns trr at 15 A/100 A/μs ensures clean commutation and prevents cross-conduction in adjacent switches. | Use Scenario: 70–150 W multi-output printer power supply with high peak current demands during motor startup. IC Role / Device Role / Timing Role: Freewheeling diode across primary-side clamp circuit and secondary-side output inductor. Use Value: Low leakage (<0.01 μA at 25 °C) prevents standby power drift; 160 A IFSM withstands motor surge currents without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY1506TR-M3 | Same VRRM/IF(AV), but 32 ns trr (typ.), higher VF (1.45 V @ 15 A/25 °C) | Slightly higher conduction loss; less effective in high-frequency DCM PFC | Select when cost sensitivity outweighs 0.35 V VF advantage and 8 ns trr penalty is acceptable |
| STTH1506D | 600 V/15 A, 35 ns trr, 1.75 V VF @ 15 A/25 °C, TO-220AC package | Through-hole mounting; higher RthJA; not suitable for high-density SMT designs | Choose only if legacy through-hole assembly or lower procurement cost is prioritized over thermal performance |
Compared with VSKY1506TR-M3 and STTH1506D, the VS-ETU1506STRR-M3 delivers superior high-temperature forward voltage and faster recovery - enabling higher efficiency in compact, thermally limited 70–400 W AC/DC systems where D2PAK thermal performance and soft switching are design-critical.

FAQ
What is the maximum allowable case temperature for VS-ETU1506STRR-M3 at 15 A average forward current?
The maximum allowable case temperature for VS-ETU1506STRR-M3 is 143 °C at 15 A IF(AV), per the Absolute Maximum Ratings table. This value is derived from thermal modeling using RthJC = 1.3 °C/W and TJ(max) = 175 °C, ensuring safe operation without exceeding junction limits under steady-state conduction.
Does VS-ETU1506STRR-M3 support lead-free reflow soldering per JEDEC J-STD-020?
Yes, VS-ETU1506STRR-M3 meets MSL level 1 and LF peak of 245 °C per J-STD-020, as confirmed in its qualification documentation. The M3 suffix explicitly denotes halogen-free, RoHS-compliant, and lead (Pb)-free terminations compatible with standard Pb-free reflow profiles.
Can VS-ETU1506STRR-M3 be used as a freewheeling diode in a flyback converter?
Yes, VS-ETU1506STRR-M3 is explicitly intended for freewheeling applications in power supplies, including flyback converters. Its 24 ns trr, low Qrr, and soft recovery minimize voltage ringing and MOSFET stress during secondary-side commutation at frequencies up to 100 kHz.
What is the reverse leakage current specification for VS-ETU1506STRR-M3 at 150 °C?
At TJ = 150 °C and rated VR, the reverse leakage current for VS-ETU1506STRR-M3 is 20–200 μA (max), per the Electrical Specifications table. This elevated leakage is typical for silicon rectifiers at high temperature but remains well below failure thresholds in properly designed PFC hold-up circuits.
Is the thermal pad on the D2PAK package of VS-ETU1506STRR-M3 electrically isolated?
No, the thermal pad on the D2PAK (TO-263AB) package of VS-ETU1506STRR-M3 is internally connected to the cathode (Pin 2). It must be soldered to a cathode-referenced copper pour to maintain electrical safety and achieve the specified RthJC = 1.3 °C/W.
