Product details
Overview
VS-4CSH01HM3/86A from Vishay Semiconductors is a hyperfast dual common-cathode rectifier in SMPC (TO-277A) package, rated 100 V reverse voltage, 2 A per diode average forward current, 24 ns typical reverse recovery time, and 0.75 V forward voltage at 2 A and 125 °C - optimized for high-frequency snubber and boost converter freewheeling paths in automotive and industrial power supplies.
For engineers reviewing the VS-4CSH01HM3/86A datasheet, VS-4CSH01HM3/86A pinout, VS-4CSH01HM3/86A application, or VS-4CSH01HM3/86A equivalent, key selection criteria include trr ≤ 25 ns, Qrr ≤ 30 nC at 125 °C, AEC-Q101 qualification, common-cathode configuration, and SMPC thermal resistance of 4.5–5.5 °C/W per diode.
Technical Context
This device integrates two hyperfast FRED Pt® rectifiers in a single common-cathode SMPC package, using platinum-doped lifetime control to achieve soft recovery and low stored charge. Its planar structure ensures ruggedness under repetitive surge conditions up to 50 A per diode (IFSM).
The VS-4CSH01HM3/86A operates with junction temperatures from –65 °C to +175 °C and is specified for both output rectification and snubber networks. Dynamic performance is characterized at dIF/dt = 200 A/μs and VR = 160 V, delivering trr = 16 ns at 25 °C and 22 ns at 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 100 V - maximum blocking voltage for DC/AC line-side and secondary-side rectification in 48 V–96 V systems |
| IF(AV) per diode | 2 A - continuous forward current rating per anode at TSp = 165 °C, supporting compact heatsink designs |
| trr (typ.) | 24 ns - enables >1 MHz switching in resonant converters without excessive EMI or switching loss penalties |
| VF @ 2 A, 125 °C | 0.75 V - reduces conduction loss by ~15% vs. standard fast rectifiers at elevated temperature |
| Qrr @ 125 °C | 30 nC - minimizes turn-on loss in synchronous rectifier-controlled topologies and limits dv/dt stress on MOSFETs |
| TJ(max) | 175 °C - supports operation in under-hood automotive environments and sealed industrial enclosures |
| RthJM per diode | 4.5–5.5 °C/W - enables direct mounting to PCB copper pour or metal-core substrate for thermal management |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads, MSL Level 1 (260 °C peak reflow), weight 0.1 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input terminal for first rectifier path | Accepts AC or pulsed input; connects to switch node in boost or flyback secondary |
| Anode 2 (Pin 2) | Input terminal for second rectifier path | Enables dual-output or interleaved topology without discrete cathode tie |
| Cathode (Pin 3) | Common output node for both diodes | Provides single low-inductance return path; critical for minimizing loop inductance in high-dI/dt applications |
Key Features
| Feature | Design Value |
|---|---|
| Hyperfast soft recovery | trr = 24 ns typ., IRRM = 2 A max at 25 °C - suppresses voltage overshoot and ringing during turn-off |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast dual common-cathode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY12010HM3/86A | Same SMPC package, 120 V VR, 24 ns trr, but higher VF (0.85 V @ 2 A, 125 °C) | Better suited for 100–120 V bus systems where margin above 100 V is required | Select when system transient overvoltage exceeds 100 V but thermal budget allows +0.1 V VF |
| VS-4CSH02HM3/86A | Identical package and construction, but 200 V VR; trr = 26 ns, Qrr = 32 nC at 125 °C | Used in 150–200 V intermediate bus converters where higher blocking is mandatory | Choose only if design requires ≥200 V rating; trade-off is +2 ns trr and +2 nC Qrr |
Compared with VS-4CSH01HM3/86A, VSKY12010HM3/86A offers higher voltage margin at slightly increased conduction loss, while VS-4CSH02HM3/86A extends blocking capability to 200 V with minimal dynamic penalty - neither is pin-compatible drop-in replacements, but both share identical SMPC footprint and thermal interface.

FAQ
What is the maximum junction temperature rating for the VS-4CSH01HM3/86A?
The VS-4CSH01HM3/86A has a maximum junction temperature (TJ(max)) of +175 °C, validated per AEC-Q101 stress testing. This rating enables operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105 °C. Derating curves in the datasheet confirm sustained 2 A per diode operation at TSp = 165 °C.
Is the VS-4CSH01HM3/86A pin-compatible with other SMPC dual-diode rectifiers?
The VS-4CSH01HM3/86A uses the standard SMPC (TO-277A) outline with Anode 1 (Pin 1), Anode 2 (Pin 2), and Common Cathode (Pin 3). While footprint and pin assignment match Vishay's eSMP® dual-diode family (e.g., VS-4CSH02HM3/86A), electrical parameters differ - no manufacturer declares it pin-compatible with non-Vishay SMPC parts. PCB layout reuse is possible only within Vishay's SMPC common-cathode series.
Does the VS-4CSH01HM3/86A meet automotive qualification standards?
Yes, the VS-4CSH01HM3/86A is AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements. It is also rated for MSL Level 1 per J-STD-020 and features halogen-free, RoHS-compliant construction. These qualifications make it suitable for automotive powertrain, body control, and ADAS subsystems where long-term reliability under thermal cycling and vibration is critical.
What is the typical reverse recovery charge (Qrr) of the VS-4CSH01HM3/86A at 125 °C?
The VS-4CSH01HM3/86A has a typical Qrr of 30 nC at TJ = 125 °C, measured under IF = 2 A, dIF/dt = 200 A/μs, and VR = 160 V. This value is confirmed in the "Dynamic Recovery Characteristics" table of datasheet 94997. At 25 °C, Qrr drops to 16 nC, reflecting temperature-dependent carrier lifetime behavior inherent to platinum-doped silicon.
How does the soft recovery characteristic of the VS-4CSH01HM3/86A benefit EMI performance?
The soft recovery of the VS-4CSH01HM3/86A - evidenced by low IRRM (2 A at 25 °C) and gradual current decay - reduces high-frequency spectral content in switching node waveforms. This directly lowers conducted and radiated EMI, easing compliance with CISPR 25 Class 5 in automotive applications and reducing filter component count in industrial power supplies.
