Product details
Overview
VS-ETL1506STRR-M3 from Vishay Semiconductors is an ultrafast FRED Pt® rectifier optimized for Discontinuous Mode (DCM) Power Factor Correction in AC/DC SMPS. It delivers 15 A average forward current, 600 V repetitive peak reverse voltage, and 60 ns typical reverse recovery time at 1 A with soft-switching characteristics for reduced EMI and snubber losses in laptop adapters and desktop PC power supplies.
For engineers reviewing the VS-ETL1506STRR-M3 datasheet, VS-ETL1506STRR-M3 pinout, VS-ETL1506STRR-M3 application, or VS-ETL1506STRR-M3 equivalent, this device is selected for high-efficiency PFC stages requiring low conduction loss (0.85 V VF at 15 A, 150 °C), 175 °C junction operation, and D2PAK (TO-263AB) surface-mount packaging with right-oriented tape-and-reel delivery.
Technical Context
This single-die ultrafast rectifier uses FRED Pt® technology to achieve soft reverse recovery with minimized stored charge (2.2 μC typical Qrr at 25 °C) and low peak recovery current (20 A IRRM), reducing switching stress on MOSFETs in critical-conduction-mode PFC circuits. Its 1.3–1.51 °C/W junction-to-case thermal resistance supports high-power-density designs when mounted on heatsinks.
The device is qualified per JEDEC JESD47, rated MSL Level 1 (245 °C reflow), and features matte tin-plated leads compliant with J-STD-002. Its D2PAK package enables high-current handling while maintaining low parasitic inductance (8.0 nH series inductance) and junction capacitance (12 pF at 600 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1506D | Same 600 V / 15 A rating but TO-220AC package; higher VF (1.15 V typ. at 15 A); 75 ns trr (1 A). | Requires through-hole mounting and larger heatsink footprint; less suitable for high-density SMT PFC designs. | Select when legacy through-hole layout exists and thermal budget allows higher conduction loss. |
| IXYS MUR1560CT | Dual common-cathode configuration in TO-220AB; each die rated 15 A / 600 V; VF = 1.0 V (15 A); trr = 65 ns. | Not single-diode; dual topology adds routing complexity and requires separate cathode tie; unsuitable for single-switch PFC. | Consider only for dual-output or redundant PFC architectures where shared cathode simplifies layout. |
Compared with STTH1506D and IXYS MUR1560CT, the VS-ETL1506STRR-M3 offers superior thermal performance in surface-mount form, lower forward voltage at high temperature, and optimized soft recovery for DCM PFC-making it the preferred choice for space- and efficiency-critical consumer power supplies.

FAQ
What is the maximum junction temperature rating for the VS-ETL1506STRR-M3?
The VS-ETL1506STRR-M3 has a maximum junction temperature of 175 °C, validated per JEDEC JESD47. This rating allows sustained operation in thermally demanding environments such as enclosed gaming console power units or slim TV power modules where ambient temperatures exceed 60 °C. The 175 °C limit provides design margin for thermal derating without compromising reliability.
Does the VS-ETL1506STRR-M3 have a soft recovery characteristic, and why does it matter?
Yes, the VS-ETL1506STRR-M3 exhibits soft reverse recovery due to its FRED Pt® silicon process, evidenced by low peak recovery current (20 A IRRM at 25 °C) and controlled di(rec)/dt. This softness reduces voltage overshoot across the switching MOSFET, lowers EMI generation, and minimizes snubber losses-critical for meeting CISPR-32 Class B emissions in consumer-grade AC/DC power supplies using the VS-ETL1506STRR-M3.
What package type and orientation does the VS-ETL1506STRR-M3 use?
The VS-ETL1506STRR-M3 is packaged in D2PAK (TO-263AB) with right-oriented tape-and-reel (TRR) configuration, as indicated by the "TRR" suffix. Pin 1 is anode, Pin 2 is cathode, and the exposed thermal pad (Pin 3) is electrically tied to the cathode. This surface-mount package supports automated assembly and efficient thermal transfer to PCB copper layers.
How does the forward voltage of the VS-ETL1506STRR-M3 compare at elevated temperature?
The VS-ETL1506STRR-M3 maintains a low forward voltage of 0.85 V at 15 A and 150 °C, significantly lower than standard fast recovery diodes (typically >1.05 V under same conditions). This temperature-stable VF reduces conduction loss drift across operating range, enabling tighter thermal design margins and improved full-load efficiency in high-ambient applications using the VS-ETL1506STRR-M3.
Is the VS-ETL1506STRR-M3 suitable for Discontinuous Conduction Mode (DCM) PFC applications?
Yes-the VS-ETL1506STRR-M3 is explicitly optimized for DCM PFC, as confirmed in Vishay's official documentation. Its combination of ultrafast recovery (60 ns trr at 1 A), low Qrr (2.2 μC), and soft switching behavior minimizes switching losses and improves power factor correction efficiency in 70–400 W AC/DC supplies such as laptop adapters and desktop PC PSUs using the VS-ETL1506STRR-M3.
