Product details
Overview
VS-8ESU06HM3/H from Vishay Semiconductors is an AEC-Q101-qualified ultrafast recovery silicon rectifier in SMPC (TO-277A) package, rated for 600 V peak reverse voltage, 8 A average forward current, and 42 ns typical reverse recovery time at 25 °C. It delivers low forward voltage drop (1.01 V at 8 A, 150 °C), soft recovery, and 175 °C maximum junction temperature - optimized for PFC and CRM snubber circuits in automotive-grade AC/DC SMPS.
For engineers reviewing the VS-8ESU06HM3/H datasheet, VS-8ESU06HM3/H pinout, VS-8ESU06HM3/H application, or VS-8ESU06HM3/H equivalent, key selection criteria include trr ≤ 63 ns at 8 A/500 A/μs, Qrr = 460 nC (25 °C), RthJM ≤ 3.5 °C/W, AEC-Q101 qualification, and halogen-free RoHS-compliant construction.
Technical Context
This device uses platinum-doped lifetime control and a planar junction structure to achieve ultrafast soft recovery with minimized stored charge (Qrr) and low reverse recovery current (IRRM = 12 A typ. at 25 °C). Its dynamic performance is characterized across temperature (25–125 °C) and dIF/dt (100–1000 A/μs), enabling stable operation in high-frequency boost converters.
The SMPC (TO-277A) package provides low thermal resistance (RthJM = 2.4–3.5 °C/W), matte tin-plated leads compliant with J-STD-002, and MSL Level 1 rating (260 °C peak reflow). It supports single-diode configuration with cathode (K) and two anode terminals (A1, A2) electrically tied internally.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06DJF | 600 V, 8 A, trr = 55 ns (typ.), VF = 1.15 V @ 8 A/150 °C, TO-252 package | Larger footprint, higher RthJA, not AEC-Q101 qualified | Preferred where board space permits and automotive qualification is not required |

FAQ
What is the maximum junction temperature rating for the VS-8ESU06HM3/H?
The VS-8ESU06HM3/H has a maximum junction temperature of 175 °C, validated per Vishay Doc. #96985. This rating allows uninterrupted operation in high-ambient environments such as under-hood automotive systems or enclosed industrial power supplies. The device maintains full 8 A IF(AV) capability up to TJ = 175 °C when mounted per recommended PCB thermal pads, and its platinum-doped die ensures parameter stability across this range.
Is the VS-8ESU06HM3/H pin-compatible with other SMPC-packaged rectifiers?
The VS-8ESU06HM3/H uses the standard SMPC (TO-277A) footprint defined in JEDEC and Vishay Doc. #95570, with K, A1, and A2 terminals in fixed positions. While mechanical mounting is compatible with other SMPC devices, electrical pinout differs: VS-8ESU06HM3/H ties A1 and A2 internally as a single anode node, whereas some dual-anode variants use independent terminals. Always verify terminal function via schematic symbol and datasheet pin diagram before substitution.
Does the VS-8ESU06HM3/H meet automotive qualification standards?
Yes, the VS-8ESU06HM3/H is explicitly AEC-Q101 qualified, as stated in the Vishay datasheet revision 23-Feb-2022 (Doc. #96985). This qualification covers stress tests including HTGB, HTRB, TCT, and UHAST, confirming suitability for automotive power electronics such as on-board chargers, DC-DC converters, and body control modules where reliability under thermal cycling and humidity is mission-critical.
What is the typical reverse recovery charge (Qrr) of the VS-8ESU06HM3/H at 125 °C?
The VS-8ESU06HM3/H exhibits a typical Qrr of 930 nC at TJ = 125 °C, per the Dynamic Recovery Characteristics table in Vishay Doc. #96985. This value is measured under IF = 8 A, dIF/dt = 500 A/μs, and VR = 400 V conditions. Elevated Qrr at high temperature directly impacts snubber sizing and MOSFET turn-on loss - designers should use this figure for worst-case loss calculations in thermally demanding applications.
How does the soft recovery characteristic of the VS-8ESU06HM3/H benefit EMI performance?
The soft recovery of the VS-8ESU06HM3/H - enabled by platinum doping and planar junction design - limits the rate of current collapse (di(rec)M/dt) during turn-off, suppressing high-frequency ringing and voltage overshoot. In practice, this reduces conducted EMI amplitude by 8–12 dB in the 30–100 MHz band, allowing smaller Y-capacitors and fewer ferrite beads in EMI filters for PFC stages meeting CISPR-25 Class 5 requirements.
