Product details
Overview
VS-8ETH06HN3 from Vishay Semiconductors is a hyperfast recovery rectifier optimized for PFC boost stages in AC/DC SMPS and inverter freewheeling applications, featuring 600 V repetitive peak reverse voltage, 8 A average forward current, 18 ns typical reverse recovery time at 1 A, 1.3 V forward voltage at 8 A and 150 °C, and AEC-Q101 qualification.
For engineers reviewing the VS-8ETH06HN3 datasheet, VS-8ETH06HN3 pinout, VS-8ETH06HN3 application, or VS-8ETH06HN3 equivalent, this page delivers verified electrical specs, TO-220AC terminal mapping, thermal resistance (RthJC = 1.4–2.0 °C/W), junction capacitance (17 pF at 600 V), and real-world recovery behavior under dIF/dt up to 600 A/μs.
Technical Context
This device uses platinum-doped lifetime control and a planar silicon structure to achieve soft, hyperfast recovery with low Qrr (25 nC typ. at 25 °C) and minimal di(rec)M/dt-induced EMI. Its 175 °C max junction temperature and 0.5 °C/W case-to-heatsink thermal resistance support high-power-density designs.
Designed for hard-switched topologies, it delivers stable trr < 33 ns even at TJ = 125 °C, IF = 8 A, dIF/dt = 600 A/μs, VR = 390 V - enabling reduced snubber losses and lower stress on MOSFETs/IGBTs in PFC and inverter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports universal AC input (85–265 VAC) with margin in PFC boost designs |
| IF(AV) | 8 A at TC = 144 °C - enables compact heatsinking in 300–500 W SMPS |
| VF @ 8 A / 150 °C | 1.3 V - reduces conduction loss by ~15% vs. standard fast diodes at elevated temperature |
| trr (typ.) | 18 ns @ IF = 1 A, dIF/dt = 100 A/μs - ensures minimal switching loss in >100 kHz PFC controllers |
| Qrr (typ.) | 25 nC @ 25 °C - lowers peak IRRM and EMI generation during turn-off |
| RthJC | 1.4–2.0 °C/W - allows direct mounting to heatsink without thermal interface pad degradation |
| TJ max | 175 °C - supports operation in automotive under-hood and industrial ambient environments |
Pinout & Package
Package: TO-220AC - single-diode configuration with isolated tab (cathode-connected base), matte tin-plated leads, UL 94 V-0 molding compound, and 2.0 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 | Anode | Main current entry point; electrically isolated from case; requires PCB trace routing for high di/dt paths |
| Lead 2 | Cathode | Common cathode connection; tied to metal tab; must be thermally coupled to heatsink |
| Tab (Base) | Cathode | Electrically and thermally connected to Lead 2; provides primary heat path to heatsink; no isolation required |
Key Features
| Feature | Design Value |
|---|---|
| Platinum-doped lifetime control | Enables precise trr and Qrr tuning without compromising VF or ruggedness across temperature |
| Soft recovery characteristic | Reduces voltage overshoot and ringing during turn-off, lowering EMI filter component count |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8L06D | 600 V, 8 A, trr = 25 ns (typ.), VF = 1.55 V @ 8 A/150 °C, TO-220AC, not AEC-Q101 qualified | Lacks automotive qualification; higher VF increases conduction loss by ~19% at 150 °C | Preferred where cost sensitivity outweighs automotive compliance and thermal margin |
| IXYS MUR860E | 600 V, 8 A, trr = 35 ns (typ.), VF = 1.7 V @ 8 A/125 °C, TO-220AC, no AEC-Q101, higher Qrr (45 nC) | Slower recovery and higher Qrr increase switching loss and EMI in >75 kHz designs | Suitable for legacy 50–60 kHz PFC where layout constraints limit snubber optimization |
Compared with STTH8L06D and IXYS MUR860E, the VS-8ETH06HN3 delivers superior thermal robustness (175 °C vs. 150 °C), lower trr/Qrr, and automotive-grade reliability - making it optimal for next-generation high-frequency, high-temperature PFC and inverter designs where efficiency and qualification matter.

FAQ
What is the maximum junction temperature rating for VS-8ETH06HN3?
The VS-8ETH06HN3 has a maximum junction temperature (TJ max) of +175 °C, validated per AEC-Q101 stress testing and confirmed in thermal characterization data. This rating enables operation in under-hood automotive environments and high-ambient industrial settings where standard 150 °C diodes would require derating or oversized heatsinks. The VS-8ETH06HN3 maintains specified trr and VF performance up to this limit.
Is VS-8ETH06HN3 pin-compatible with other TO-220AC rectifiers?
Yes, the VS-8ETH06HN3 uses the standard JEDEC TO-220AC outline with Anode on Lead 1, Cathode on Lead 2 and Tab - matching mechanical and electrical pinout of industry-standard 8 A, 600 V TO-220AC rectifiers. Mounting hole spacing, lead pitch, and tab dimensions comply with document 95221, ensuring drop-in replacement in existing layouts without PCB revision.
Does VS-8ETH06HN3 meet automotive qualification standards?
Yes, the VS-8ETH06HN3 is AEC-Q101 qualified and passes JESD201 Class 2 whisker testing. Its construction - including platinum doping, planar die architecture, and halogen-free molding compound - was specifically validated for automotive powertrain and body electronics applications. The "H" in the part number explicitly denotes AEC-Q101 compliance per Vishay's marking convention.
What is the typical reverse recovery charge (Qrr) of VS-8ETH06HN3 at 125 °C?
The typical reverse recovery charge (Qrr) of VS-8ETH06HN3 is 120 nC at TJ = 125 °C, IF = 8 A, dIF/dt = 100 A/μs, and VR = 30 V - per Dynamic Recovery Characteristics table on page 2 of document 94768. This value increases from 25 nC at 25 °C, reflecting temperature-dependent carrier lifetime effects critical for thermal design in high-power applications.
How does the forward voltage of VS-8ETH06HN3 compare at elevated temperature?
At 8 A and TJ = 150 °C, the VS-8ETH06HN3 exhibits a forward voltage (VF) of 1.3 V (typ.) - significantly lower than conventional fast recovery diodes (typically ≥1.6 V). This low VF at high temperature directly reduces conduction losses in PFC boost diodes, improving full-load efficiency and easing thermal management in compact power supplies.
