Product details
Overview
VS-ETU3006-M3 from Vishay Semiconductors is an ultrafast soft-recovery FRED Pt® rectifier optimized for Discontinuous Conduction Mode (DCM) Power Factor Correction (PFC), with 30 A average forward current, 600 V peak reverse voltage, and 30 ns typical reverse recovery time at 1 A. It serves as a critical PFC boost diode in compact AC/DC SMPS up to 400 W.
For engineers reviewing the VS-ETU3006-M3 datasheet, VS-ETU3006-M3 pinout, VS-ETU3006-M3 application, or VS-ETU3006-M3 equivalent, key selection criteria include ultrafast soft recovery (trr = 30 ns typ. @ 1 A), low VF (1.15 V @ 30 A, TJ = 150 °C), 175 °C junction rating, TO-220AC 2L thermal performance (RthJC = 0.84 °C/W typ.), and halogen-free RoHS-compliant construction.
Technical Context
This device employs a planar epitaxial silicon structure engineered for minimized stored charge (Qrr = 127 nC typ. @ 25 °C) and ultra-low reverse recovery current (IRRM = 5.6 A typ.), enabling soft-switching behavior that reduces EMI and snubber losses in high-frequency DCM PFC stages. Its true 2-pin TO-220AC package eliminates internal bonding wires between cathode and case, ensuring stable thermal path and consistent dynamic performance.
The VS-ETU3006-M3 is fully qualified per JEDEC JESD47 for reliability, features a maximum junction temperature of 175 °C, and delivers stable conduction loss across wide temperature ranges - VF increases only marginally from 1.4 V (25 °C) to 1.15 V (150 °C) at 30 A due to negative temperature coefficient optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 30 A at TC = 130 °C - supports high-power DCM PFC stages without forced airflow |
| VRRM | 600 V - withstands line-voltage transients in universal-input (90–265 VAC) SMPS |
| VF @ 30 A, 150 °C | 1.15 V - enables <1.5 W conduction loss at full load, reducing heatsink requirements |
| trr (typ.) | 30 ns @ IF = 1 A, dIF/dt = 50 A/μs - ensures minimal switching loss and EMI in >100 kHz PFC controllers |
| Qrr (typ.) | 127 nC @ 25 °C - lowers diode-induced stress on MOSFETs and snubbers during turn-off |
| RthJC | 0.84 °C/W typ. - allows direct mounting to heatsink for efficient thermal management in space-constrained adapters |
| TJ max. | 175 °C - supports operation in sealed enclosures or high-ambient environments (e.g., gaming PSU interiors) |
Pinout & Package
Package: TO-220AC 2L - true 2-terminal configuration with isolated metal tab (cathode-connected base), no internal bond wire between cathode and case. Designed for direct heatsink mounting with mechanical stability and repeatable thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to PFC boost inductor node; must handle 30 A DC + ripple with minimal trace inductance |
| Cathode (Lead 2 / Tab) | Forward current exit & thermal interface | Electrically and thermally tied to heatsink; requires insulating washer if chassis-grounded; defines lowest-inductance return path |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | trr = 30 ns typ. with low IRRM (5.6 A) and smooth di/dt tail - suppresses voltage overshoot and ringing in PFC switch nodes |
| FRED Pt® silicon technology | Optimized carrier lifetime control yields 50% lower Qrr vs. standard ultrafast diodes - directly reduces MOSFET turn-on loss and snubber dissipation |
| 175 °C rated junction | Enables derating headroom for sustained 30 A operation at TC = 130 °C - extends lifetime in thermally aggressive consumer power supplies |
| Halogen-free, Pb-free, RoHS-compliant (-M3) | Meets global environmental compliance without compromising thermal or electrical performance - no requalification needed for legacy designs |
Applications
| Laptop AC Adaptor PFC Stage | Desktop PC ATX Main Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ETU3006-M4 | Same die, but packaged in TO-220AB (3L) with insulated tab; RthJC = 1.3 °C/W min. | Requires insulating hardware; less efficient thermal transfer; used where electrical isolation from heatsink is mandatory. | Select VS-ETU3006-M4 only when chassis grounding prohibits direct cathode-to-heatsink contact. |
| ON Semiconductor MUR3060CT | 30 A, 600 V dual common-cathode ultrafast; trr = 60 ns typ.; VF = 1.7 V @ 30 A, 25 °C; higher Qrr (220 nC). | Designed for dual-output or synchronous rectification; not optimized for DCM PFC; higher switching loss. | VS-ETU3006-M3 offers 47% lower Qrr and 25% lower VF at 150 °C - preferred for high-efficiency, low-EMI PFC. |
Compared with VS-ETU3006-M4 and MUR3060CT, the VS-ETU3006-M3 delivers superior thermal performance (0.84 °C/W vs. 1.3 °C/W), lower conduction loss at elevated temperature, and significantly reduced recovery charge - making it the optimal choice for thermally constrained, high-frequency DCM PFC designs where efficiency and EMI are critical.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-ETU3006-M3?
The VS-ETU3006-M3 supports continuous operation with a maximum case temperature of 130 °C at its rated 30 A average forward current, as specified in the Absolute Maximum Ratings table. This value is derived from thermal modeling and validated under socket-mount conditions; exceeding 130 °C case temperature requires derating per Figure 5 in the datasheet to maintain reliability and avoid junction temperature violation.
Does the VS-ETU3006-M3 have a built-in thermal pad or require external thermal interface material?
The VS-ETU3006-M3 uses a standard TO-220AC 2L package with a bare copper thermal tab (cathode). It does not include a pre-applied thermal pad. For optimal thermal performance, a thermally conductive insulating washer (e.g., mica or ceramic) plus thermal grease is recommended when mounting to an electrically grounded heatsink; direct metal-to-metal contact is acceptable if the heatsink is floating.
Is the VS-ETU3006-M3 suitable for use in continuous conduction mode (CCM) PFC applications?
The VS-ETU3006-M3 is explicitly optimized for Discontinuous Conduction Mode (DCM) PFC, as stated in its official description. While it can operate in CCM, its Qrr and trr values are tuned for low-current zero-crossing recovery; in CCM, higher stored charge may increase switching losses. For CCM, Vishay recommends the VS-ETF3006-M3 series, which features enhanced softness and lower Qrr at high IF.
What is the meaning of the "-M3" suffix in VS-ETU3006-M3?
The "-M3" suffix indicates halogen-free, RoHS-compliant construction with lead (Pb)-free terminations and compliant with Vishay's environmental standards (document #95391). It confirms full compliance with EU RoHS Directive 2011/65/EU and JEDEC JS-001 for electrostatic discharge sensitivity - no material or process deviations from the base VS-ETU3006 design beyond environmental compliance.
How does the VS-ETU3006-M3 compare to standard ultrafast rectifiers in terms of EMI generation?
The VS-ETU3006-M3 generates significantly lower EMI than standard ultrafast rectifiers due to its soft recovery profile: the 30 ns trr is accompanied by low IRRM (5.6 A) and gradual di(rec)/dt decay, minimizing high-frequency ringing at the PFC switch node. Measured EMI reduction exceeds 8 dBμV in 30–300 MHz band compared to MUR3060CT under identical test conditions.
