Product details
Overview
VS-4CSH02HM3/86A from Vishay Semiconductors is a dual common-cathode hyperfast recovery rectifier in SMPC (TO-277A) package, rated 200 V reverse voltage, 2 A per diode average forward current, and 24 ns typical reverse recovery time at 25 °C. It delivers low forward voltage (0.75 V at 2 A, 125 °C), soft recovery, and AEC-Q101 qualification - designed for high-frequency snubber and boost circuits in automotive power supplies.
For engineers reviewing the VS-4CSH02HM3/86A datasheet, VS-4CSH02HM3/86A pinout, VS-4CSH02HM3/86A application, or VS-4CSH02HM3/86A equivalent, key selection criteria include trr ≤ 25 ns, Qrr ≤ 30 nC at 125 °C, TJ max = 175 °C, common-cathode configuration, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This device integrates two platinum-doped FRED Pt® diodes in a planar structure to achieve optimized trade-off between forward conduction loss and switching performance. Its hyperfast recovery is enabled by controlled carrier lifetime, resulting in low Qrr (16 nC typ. at 25 °C) and soft reverse recovery waveform with minimal voltage overshoot.
The common-cathode configuration supports synchronous freewheeling and interleaved boost topologies. Thermal resistance RthJM is 4.5–5.5 °C/W per diode, enabling high-power-density designs when mounted on thermally robust PCB pads per JEDEC TO-277A footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V repetitive reverse voltage without breakdown, suitable for 12 V–48 V automotive DC-DC stages. |
| IF(AV) per diode | 2 A - continuous average forward current rating per anode under TSp = 165 °C mounting condition. |
| VF @ 2 A, 125 °C | 0.75 V - low conduction loss enables <1.5 W forward power dissipation per diode at 2 A DC. |
| trr (typ.) | 24 ns - ultra-fast recovery minimizes switching losses in >100 kHz converters and reduces EMI generation. |
| Qrr (typ., 125 °C) | 30 nC - low stored charge reduces turn-off stress on MOSFETs/IGBTs in hard-switched topologies. |
| TJ max | 175 °C - extended junction temperature rating supports operation in under-hood automotive environments. |
| RthJM | 4.5–5.5 °C/W - thermal resistance from junction to mount surface enables direct heatsinking via PCB copper area. |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Dimensions conform to JEDEC TO-277A standard; mounting pad layout requires 0.268" × 0.186" (6.80 mm × 4.72 mm) copper area for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input terminal for first diode | Connects to switching node in boost converter or snubber circuit; rated for 50 A non-repetitive surge. |
| Anode 2 (Pin 3) | Input terminal for second diode | Enables dual-channel operation - e.g., interleaved PFC or dual-phase output rectification. |
| Cathode (Pin 2) | Common output node | Shared cathode simplifies PCB routing and reduces parasitic inductance in high-di/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| Hyperfast soft recovery | trr ≤ 25 ns with low IRRM (≤3 A) and smooth di/dt transition - reduces EMI and gate drive stress on adjacent switches. |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per JESD201 Class 2 whisker test - supports PPAP-ready designs. |
| FRED Pt® lifetime control | Platinum doping ensures stable trr and Qrr over temperature and lifetime - eliminates parameter drift in 15-year deployments. |
| MSL Level 1 | Rated for peak reflow at 260 °C - compatible with standard lead-free SMT assembly without baking or special handling. |
| Low leakage at 125 °C | IR ≤ 8 μA at VR = 200 V and TJ = 125 °C - maintains efficiency in high-temperature hold conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-4CSH02HM3/87A | Identical electrical specs and package; differs only in reel quantity (6500 vs. 1500) and tape/reel diameter (13" vs. 7"). | No functional difference; selected for high-volume production runs requiring longer reel life. | Choose /87A for automated SMT lines with large batch builds; /86A suits prototyping and medium-volume releases. |
| ON Semiconductor NCV47822MNTXG | Single-diode AEC-Q101 hyperfast rectifier (200 V, 2 A, trr = 25 ns), SO-8FL package; no common-cathode dual configuration. | Lacks dual-anode integration - requires two devices and extra PCB area to match VS-4CSH02HM3/86A functionality. | Select only if board space permits discrete placement and thermal management supports SO-8FL's higher RthJA. |
Compared with VS-4CSH02HM3/86A, the /87A variant offers identical performance with larger reel packaging for production efficiency, while the NCV47822MNTXG provides AEC-Q101 compliance in a different form factor but lacks integrated dual-anode convenience and thermal advantage of SMPC mounting.

FAQ
What is the maximum junction temperature rating for VS-4CSH02HM3/86A?
The VS-4CSH02HM3/86A has a maximum junction temperature (TJ max) of 175 °C, validated per AEC-Q101 stress testing. This rating allows sustained operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet show allowable IF(AV) decreases linearly above 125 °C case temperature, with full 2 A per diode rating maintained up to TSp = 165 °C mounting point temperature.
Is VS-4CSH02HM3/86A pin-compatible with other Vishay SMPC dual-diode rectifiers?
Yes - VS-4CSH02HM3/86A uses the standard SMPC (TO-277A) footprint defined in Vishay document 95570, with identical pin 1 (Anode 1), pin 2 (Cathode), and pin 3 (Anode 2) assignment. It shares mechanical compatibility with VS-4CSH04HM3 and VS-4CSH06HM3, though voltage and current ratings differ; PCB layout can be reused across this family with electrical validation.
Does VS-4CSH02HM3/86A meet lead-free soldering requirements?
Yes - VS-4CSH02HM3/86A is RoHS-compliant, halogen-free, and features matte tin-plated terminations qualified per J-STD-002 for solderability. It is rated MSL Level 1 and supports peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free SMT processes without pre-baking or special handling.
What is the reverse recovery charge (Qrr) of VS-4CSH02HM3/86A at elevated temperature?
At TJ = 125 °C, the VS-4CSH02HM3/86A exhibits a typical Qrr of 30 nC under standard test conditions (IF = 2 A, dIF/dt = 200 A/μs, VR = 160 V). This value is confirmed in the "Dynamic Recovery Characteristics" table of datasheet 94973 and reflects real-world degradation of carrier lifetime at high temperature - critical for loss calculation in hot-running boost converters.
How is the common-cathode configuration of VS-4CSH02HM3/86A leveraged in interleaved PFC designs?
In interleaved PFC, the VS-4CSH02HM3/86A's common-cathode architecture allows both anodes to feed separate boost phases while sharing a single low-inductance cathode return path to the output capacitor. This reduces layout complexity, minimizes ground loop area, and improves current balance - directly lowering total harmonic distortion (THD) and thermal asymmetry versus discrete diode solutions.
