Product details
Overview
VS-35EPF06LHM3 from Vishay Semiconductors is a fast soft recovery rectifier diode rated for 35 A average forward current and 600 V peak reverse voltage, with 1.27 V forward voltage at 15 A and 25 °C, 60 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability in on-board EV battery chargers.
For engineers reviewing the VS-35EPF06LHM3 datasheet, VS-35EPF06LHM3 pinout, VS-35EPF06LHM3 application, or VS-35EPF06LHM3 equivalent, this device supports high-efficiency AC/DC rectification in high-surge, high-temperature environments where low conduction loss and controlled recovery behavior are critical.
Technical Context
This single-diode configuration uses a glass-passivated pellet chip junction to achieve very low forward voltage drop (1.46 V at 35 A, 25 °C) while maintaining moderate leakage (6 mA at 150 °C) and short reverse recovery time (160 ns at 20 A, 100 A/μs, 25 °C). Its snap factor of 0.6 indicates controlled soft recovery behavior ideal for reducing EMI in switching power stages.
The TO-247AD 2L package provides low thermal resistance (0.6 °C/W junction-to-case) and direct base-cathode mounting, enabling efficient heat dissipation in high-power DC charging stations and renewable energy inverters operating up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 35 A - maximum continuous average forward current at TC = 103 °C, suitable for high-duty-cycle rectifier bridges |
| VRRM | 600 V - peak repetitive reverse voltage rating, enabling use in 400 V AC line and 600 V DC bus applications |
| VF at 15 A, 25 °C | 1.27 V - low conduction loss reduces power dissipation and improves system efficiency in high-current paths |
| trr | 60 ns - measured under 1 A, 100 A/μs conditions; enables high-frequency operation with reduced switching losses |
| IFSM | 320 A - non-repetitive surge current capability (10 ms sine pulse, no voltage reapplied), supporting robust inrush handling |
| RthJC | 0.6 °C/W - low junction-to-case thermal resistance allows direct heatsink mounting without thermal interface degradation |
| AEC-Q101 | Qualified - meets JESD201 Class 1A whisker test, confirming suitability for automotive on-board charger modules |
Pinout & Package
VS-35EPF06LHM3 is housed in a TO-247AD 2L package with isolated metal base acting as cathode terminal and single anode lead. The 2-pin configuration eliminates internal connection ambiguity and simplifies PCB layout for high-current, low-inductance paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Base (Metal Tab) | Cathode | Electrically active thermal path; must be electrically isolated from heatsink unless system design permits common-cathode grounding |
| Lead 1 (Anode) | Anode | Single high-current input terminal; optimized for low-inductance connection to AC source or bridge input node |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF | 1.46 V at 35 A, 25 °C - minimizes conduction loss in high-current rectification, directly improving thermal margin |
| Glass passivation | Hermetic junction protection - ensures long-term reliability under humidity, thermal cycling, and bias stress |
| Fast soft recovery | Snap factor = 0.6 - suppresses voltage overshoot and EMI during turn-off, easing EMI filter design |
| AEC-Q101 qualified | JESD201 Class 1A whisker test passed - validated for automotive-grade deployment without derating |
| TO-247AD 2L | 0.6 °C/W RthJC - enables >90 W power dissipation at ΔT = 54 °C, supporting compact thermal solutions |
Applications
| On-board EV Battery Charger | Off-board DC Fast Charging Station |
|---|---|
Use Scenario: High-power AC/DC conversion in vehicle-integrated bidirectional chargers operating at 11–22 kW. IC Role / Device Role / Timing Role: Main rectifier in three-phase uncontrolled or semi-controlled bridge, conducting full-line current during positive half-cycles. Use Value: Low VF (1.27 V) reduces conduction loss by ~12% vs. standard 600 V fast recovery diodes, lowering heatsink requirements. |
Use Scenario: Front-end rectification in 150–350 kW liquid-cooled DC fast chargers with multi-level topologies. IC Role / Device Role / Timing Role: Surge-tolerant output rectifier in secondary-side synchronous or hybrid rectifier stages. Use Value: 320 A IFSM and 60 ns trr support high dI/dt transients during fault clearing and enable faster gate drive timing margins. |
| Renewable Energy Inverter | Industrial Motor Drive Rectifier |
Use Scenario: Grid-tied solar or wind inverters requiring high-voltage DC link formation from AC generator output. IC Role / Device Role / Timing Role: Input-stage rectifier in boost PFC or Vienna rectifier front ends, handling 50/60 Hz and harmonic-rich waveforms. Use Value: 150 °C TJ max and 0.6 °C/W RthJC allow sustained operation at 95% load in outdoor-rated enclosures without forced air. |
Use Scenario: Regenerative braking energy recovery circuits in HVAC and industrial servo drives. IC Role / Device Role / Timing Role: Bidirectional freewheeling diode in IGBT-based inverter legs, conducting reverse current during motor deceleration. Use Value: Soft recovery (snap factor 0.6) limits voltage spikes across IGBTs, reducing snubber component count and cost. |
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 |
|---|---|---|---|
| VS-35APF06LHM3 | Same die, TO-247AD 3L package with separate anode/cathode/thermal tab leads; 3-pin layout adds routing flexibility but increases parasitic inductance | Preferred where independent anode/cathode routing or thermal pad isolation is required; not pin-compatible with VS-35EPF06LHM3 | Select VS-35APF06LHM3 only when board layout requires 3-terminal separation or thermal pad grounding independence. |
| STTH30L06D | 600 V, 30 A, 1.85 V VF at 15 A, 100 ns trr, TO-247AC package; higher VF and slower recovery than VS-35EPF06LHM3 | Acceptable in lower-efficiency or cost-sensitive industrial SMPS where 5 A current margin and 40 ns slower recovery are tolerable | Choose STTH30L06D only if thermal budget allows +3.2 W extra conduction loss per device and EMI filtering can accommodate longer trr. |
Compared with VS-35APF06LHM3, the VS-35EPF06LHM3 offers lower package inductance and simpler layout via its 2-pin base-cathode configuration; versus STTH30L06D, it delivers 0.58 V lower VF and 40 ns faster trr-directly enabling higher efficiency and tighter EMI compliance in automotive and renewable energy systems.

FAQ
What is the maximum junction temperature rating for VS-35EPF06LHM3?
The VS-35EPF06LHM3 has a maximum junction temperature (TJ) rating of +150 °C, verified across its full operating range from –40 °C to +150 °C. This rating is supported by its glass-passivated junction and TO-247AD 2L package with 0.6 °C/W junction-to-case thermal resistance, allowing reliable operation in high-ambient environments such as under-hood EV charger modules.
Is VS-35EPF06LHM3 pin-compatible with VS-35APF06LHM3?
No, VS-35EPF06LHM3 is not pin-compatible with VS-35APF06LHM3. The VS-35EPF06LHM3 uses a TO-247AD 2L package with base-cathode configuration, while VS-35APF06LHM3 uses TO-247AD 3L with separate anode, cathode, and thermal tab leads. Their pinouts differ fundamentally-VS-35EPF06LHM3 has two terminals (base cathode + anode lead), whereas VS-35APF06LHM3 has three distinct leads.
What does the 'H' suffix in VS-35EPF06LHM3 indicate?
The 'H' suffix in VS-35EPF06LHM3 denotes AEC-Q101 qualification per JESD201 Class 1A whisker test, confirming the device meets automotive reliability standards for use in on-board and off-board EV battery chargers. This qualification is explicitly documented in Vishay's datasheet revision 22-Feb-18 (Document Number: 96494).
What is the reverse recovery time (trr) specification for VS-35EPF06LHM3 under typical operating conditions?
The VS-35EPF06LHM3 specifies trr = 60 ns under test conditions of 1 A forward current and 100 A/μs di/dt at 25 °C. At higher stress levels (20 A, 100 A/μs, 25 °C), trr increases to 160 ns-both values are measured and published in the official datasheet, reflecting its fast soft recovery behavior essential for minimizing switching losses and EMI.
Does VS-35EPF06LHM3 support RoHS and halogen-free compliance?
Yes, the 'M3' suffix in VS-35EPF06LHM3 confirms full compliance with RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. The device features lead (Pb)-free terminations and halogen-free molding compound, as verified in Vishay's material declaration documentation referenced in the datasheet.
