Product details
Overview
VS-4ESH01HM3/86A from Vishay Semiconductors is a hyperfast recovery rectifier diode in SMPC (TO-277A) package, rated for 100 V peak reverse voltage, 4 A average forward current, and 27 ns typical reverse recovery time at 25 °C. It features low forward voltage drop (0.73 V at 4 A, 125 °C), 175 °C maximum junction temperature, and AEC-Q101 qualification - designed for high-frequency snubber and boost circuits in automotive power supplies.
For engineers reviewing the VS-4ESH01HM3/86A datasheet, VS-4ESH01HM3/86A pinout, VS-4ESH01HM3/86A application, or VS-4ESH01HM3/86A equivalent, key selection criteria include trr ≤ 31 ns at 125 °C, Qrr = 70 nC at TJ = 125 °C, RthJM ≤ 3 °C/W, soft recovery behavior, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This device employs platinum-doped lifetime control on a planar silicon structure to achieve optimized trade-off between forward conduction loss and switching performance. Its hyperfast recovery (trr down to 20 ns at 25 °C under high dIF/dt) and low stored charge minimize switching losses in hard-switched topologies.
The SMPC package enables low thermal resistance (RthJM typ. 2.2 °C/W) and supports high-power-density mounting on PCBs with direct case thermal coupling. AEC-Q101 qualification confirms robustness for automotive under-hood applications requiring operation from –55 °C to +175 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4L06S | 600 V VRRM, 4 A IF(AV), trr = 35 ns (25 °C), VF = 1.15 V @ 4 A | Higher voltage rating but higher VF and slower recovery - suited for 600 V PFC, not 100 V snubbers | Select only if system requires >100 V blocking; avoid where low VF or <30 ns trr is critical |
| IXYS MBR4100CT | 100 V VRRM, dual common-cathode Schottky, VF = 0.65 V @ 4 A, no recovery time | No reverse recovery but limited to TJ ≤ 150 °C and higher IR - unsuitable for 175 °C ambient | Prefer for low-VF, low-noise apps below 150 °C; reject for AEC-Q101 or >150 °C operation |
Compared with STTH4L06S and IXYS MBR4100CT, the VS-4ESH01HM3/86A uniquely balances 100 V rating, 27 ns trr, 0.73 V VF at 125 °C, and AEC-Q101 compliance - making it optimal for thermally demanding, high-frequency automotive snubber and boost applications where Schottky limitations or Si hyperfast trade-offs must be avoided.

FAQ
What is the maximum junction temperature rating for the VS-4ESH01HM3/86A?
The VS-4ESH01HM3/86A has a maximum junction temperature of 175 °C, verified per absolute maximum ratings in Vishay Document #94999. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial power supplies. Derating curves in Figure 4 confirm allowable case temperature versus average forward current up to this limit.
Is the VS-4ESH01HM3/86A suitable for lead-free reflow soldering?
Yes, the VS-4ESH01HM3/86A meets MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads are solderable per J-STD-002, and the molding compound is UL 94 V-0 rated. No pre-baking is required prior to assembly.
Does the VS-4ESH01HM3/86A have AEC-Q101 qualification?
Yes, the VS-4ESH01HM3/86A is explicitly AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements. This qualification is documented in the "Features" section of Vishay Document #94999 and confirmed in the ordering information decoding table.
What is the reverse recovery time (trr) of the VS-4ESH01HM3/86A at elevated temperature?
The VS-4ESH01HM3/86A exhibits a typical trr of 31 ns at TJ = 125 °C under IF = 4 A, dIF/dt = 200 A/μs, and VR = 160 V. This value is specified in the Dynamic Recovery Characteristics table (page 2 of Document #94999) and reflects real-world performance in thermally stressed switching applications.
How is the anode configured on the VS-4ESH01HM3/86A in the SMPC package?
The VS-4ESH01HM3/86A uses a dual-anode configuration: Anode 1 and Anode 2 are internally paralleled within the SMPC (TO-277A) package. This design lowers effective series inductance and improves current distribution, as shown in the mechanical diagram and pinout description on page 1 of Document #94999.
