Product details
Overview
VS-10ETF04STRL-M3 from Vishay Semiconductors is a surface-mount fast soft recovery rectifier diode rated for 400 V peak reverse voltage (VRRM), 10 A average forward current (IF(AV)), and 1.2 V forward voltage drop at 10 A and 25 °C. It features 50 ns reverse recovery time (trr), 0.6 snap factor, and D2PAK (TO-263AB) package with base cathode configuration - optimized for high-efficiency output rectification in DC/DC converters and freewheeling in motor choppers.
For engineers reviewing the VS-10ETF04STRL-M3 datasheet, VS-10ETF04STRL-M3 pinout, VS-10ETF04STRL-M3 application, or VS-10ETF04STRL-M3 equivalent, key selection criteria include its soft recovery behavior (low EMI), thermal resistance of 1.5 °C/W (junction-to-case), 140 A non-repetitive surge rating, and RoHS-compliant halogen-free construction - critical for industrial power supplies and automotive-grade inverters requiring stable switching performance under thermal cycling.
Technical Context
This diode employs a glass-passivated pellet chip junction qualified to JEDEC JESD47, meeting MSL level 1 (245 °C peak reflow). Its soft recovery profile minimizes voltage overshoot and ringing during commutation, reducing conducted EMI in high-frequency switching topologies.
The D2PAK package enables high-power dissipation with low thermal resistance (RthJC = 1.5 °C/W) and supports PCB mounting on 1"² FR-4 copper (4 oz), delivering 40 °C/W junction-to-ambient thermal resistance under standard conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive peak reverse voltage; defines safe blocking capability in 400 V bus applications |
| IF(AV) | 10 A - average forward current at TC = 128 °C; supports continuous conduction in high-current power stages |
| trr | 50 ns - reverse recovery time at 1 A, 100 A/μs; enables operation up to ~200 kHz with controlled turn-off loss |
| VF | 1.2 V at 10 A, 25 °C - low forward drop reduces conduction loss and improves efficiency in 12–48 V output stages |
| Snap factor | 0.6 - ratio of peak reverse recovery current to diode forward current; indicates soft recovery for low EMI |
| RthJC | 1.5 °C/W - junction-to-case thermal resistance; allows direct heatsinking via PCB copper pour or external heatsink |
| IFSM | 140 A - non-repetitive surge current (10 ms sine pulse, no voltage reapplied); withstands inrush and fault transients |
Pinout & Package
Package: D2PAK (TO-263AB), surface-mount, single-diode configuration with base cathode (pin 2 = cathode tab). Thermal pad on underside provides primary heat path to PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Input terminal for forward current flow; connects to switching node or transformer secondary |
| 2 (Cathode Tab) | Cathode / thermal pad | Primary current return path and main thermal interface; must be soldered to large copper area for thermal management |
| 3 (Anode) | Anode connection | Second anode lead for mechanical stability and parallel current path; electrically tied to pin 1 |
Key Features
| Feature | Design Value |

| Soft recovery (S = 0.6) | Reduces high-frequency ringing and EMI during turn-off, easing compliance with CISPR-22/EN55022 Class B |
| D2PAK thermal performance | 1.5 °C/W RthJC enables >10 W power dissipation with minimal case temperature rise under DC load |
| JEDEC JESD47 qualification | Validated reliability for industrial and automotive environments, including temperature cycling and humidity testing |
| Halogen-free, RoHS-compliant | M3 suffix confirms lead-free terminations and halogen-free molding compound per IEC 61249-2-21 |
Applications
| Motor Drive Freewheeling | DC/DC Converter Output Rectification |
|---|---|
|
Use Scenario: Bidirectional energy recirculation in H-bridge motor drivers during PWM dead-time. IC Role / Device Role / Timing Role: Freewheeling diode providing low-loss current path when upper/lower MOSFETs are off. Use Value: 50 ns trr and soft recovery minimize voltage spikes across MOSFETs, reducing stress and enabling higher PWM frequency. |
Use Scenario: Secondary-side rectification in isolated flyback or forward converters for industrial PLC power supplies. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC bus. Use Value: 1.2 V VF at 10 A lowers conduction loss by ~15% vs. standard fast recovery diodes, improving full-load efficiency. |

IC Role / Device Role / Timing Role: Input rectifier managing line-frequency AC conversion with minimal high-frequency noise generation. Use Value: Snap factor of 0.6 ensures smooth reverse recovery, reducing differential-mode noise on primary-side filter components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast soft recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY1004 | 400 V VRRM, 10 A IF(AV), but trr = 75 ns and VF = 1.35 V at 10 A - slower, higher conduction loss | Higher EMI risk in >100 kHz designs; less suitable for compact EMI-filter-limited layouts | Acceptable where cost sensitivity outweighs efficiency/EMI requirements |
| STTH10R04DJF | 400 V VRRM, 10 A IF(AV), trr = 45 ns, VF = 1.15 V - slightly faster and lower VF, but TO-220AC package (higher RthJA) | Requires through-hole mounting and external heatsink; unsuitable for fully SMT production | Preferred only if board-level thermal design permits discrete heatsinking and layout accommodates through-hole footprint |
Compared with VSKY1004 and STTH10R04DJF, the VS-10ETF04STRL-M3 delivers optimal balance of soft recovery (0.6 snap factor), low thermal resistance (1.5 °C/W), and SMT manufacturability - making it the preferred choice for space-constrained, high-efficiency, EMI-sensitive power stages where D2PAK mounting is feasible.

FAQ
What is the maximum junction temperature rating for the VS-10ETF04STRL-M3?
The VS-10ETF04STRL-M3 has a maximum junction temperature (TJ) of +150 °C, validated per JEDEC JESD47 qualification. This rating allows reliable operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations when mounted with adequate PCB copper thermal mass. The device maintains specified electrical parameters up to this limit.
Does the VS-10ETF04STRL-M3 have a built-in thermal pad, and how should it be connected?
Yes, the VS-10ETF04STRL-M3 uses a D2PAK (TO-263AB) package with an exposed cathode thermal pad (pin 2) that serves as both electrical cathode and primary thermal interface. It must be soldered to a minimum 1"² (650 mm²) FR-4 PCB copper area with 4 oz (140 μm) copper thickness to achieve the specified 40 °C/W RthJA. Thermal vias under the pad are recommended for enhanced heat transfer to internal layers.
How does the snap factor of 0.6 affect EMI performance in the VS-10ETF04STRL-M3?
The snap factor of 0.6 in the VS-10ETF04STRL-M3 quantifies its soft recovery behavior - indicating moderate peak reverse recovery current relative to forward current. This reduces high-frequency spectral content during turn-off, lowering both conducted and radiated EMI compared to standard fast recovery diodes (snap factor > 0.8). It directly eases compliance with EN 55022 Class B limits without oversized input filters.
Is the VS-10ETF04STRL-M3 suitable for use in automotive applications?
The VS-10ETF04STRL-M3 is not AEC-Q101 qualified, but its JEDEC JESD47 qualification, -40 °C to +150 °C operating range, and glass-passivated junction support use in non-safety-critical automotive subsystems - such as body control modules or infotainment power supplies - provided system-level validation confirms robustness under vehicle-specific thermal and vibration profiles.
What is the difference between VS-10ETF04S-M3 and VS-10ETF04STRL-M3?
The VS-10ETF04STRL-M3 is identical in die and package to VS-10ETF04S-M3 but supplied in left-oriented tape-and-reel packaging (TRL), whereas VS-10ETF04S-M3 is supplied in antistatic plastic tubes. Both share identical electrical, thermal, and reliability specifications - the suffix change reflects only packaging format and orientation for automated pick-and-place compatibility.
