Product details
Overview
SK86C R7G from Taiwan Semiconductor is a single-die, 60 V repetitive peak reverse voltage Schottky barrier rectifier in DO-214AB (SMC) package, rated for 8 A average forward current and 150 A non-repetitive surge current, with 0.75 V typical forward voltage at 8 A and 25°C, used in high-efficiency SMPS secondary-side rectification.
For engineers reviewing the SK86C R7G datasheet, SK86C R7G pinout, SK86C R7G application, or SK86C R7G equivalent, key selection criteria include VRRM = 60 V, IF = 8 A, VF = 0.75 V (typ), IR = 10 mA @ 100°C, and thermal resistance RθJA = 20 °C/W - all critical for power loss budgeting and thermal design in compact AC/DC adapters and DC-DC converters.
Technical Context
The SK86C R7G implements a planar Schottky junction structure optimized for low forward voltage and fast switching, with no minority-carrier storage delay. Its guard ring design enhances ruggedness against transient overvoltage events common in flyback and LLC converter topologies.
Rated for continuous operation up to 150°C junction temperature and moisture sensitivity level 1 (J-STD-020), it supports lead-free reflow soldering and meets JESD201 Class 2 whisker resistance requirements - enabling reliable automated placement in high-volume industrial and consumer power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - maximum reverse blocking capability; defines safe operating range in 48 V output SMPS designs |
| IF | 8 A - continuous average forward current; sets minimum heatsink requirement for 60–100 W adapter outputs |
| VF (typ) | 0.75 V @ 8 A, 25°C - directly determines conduction loss (6.0 W at full load), critical for efficiency optimization |
| IFSM | 150 A - peak surge rating for 8.3 ms half-sine; withstands inrush and fault transients without failure |
| RθJA | 20 °C/W - junction-to-ambient thermal resistance; enables thermal modeling for PCB copper area and airflow planning |
| IR @ 100°C | 10 mA - reverse leakage at elevated temperature; impacts standby power and light-load regulation stability |
| dV/dt | 10,000 V/µs - critical rate-of-rise immunity; prevents false turn-on during high dv/dt switching node transitions |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode-indicating band; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to transformer secondary or low-side switch node; must handle full 8 A RMS current path |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output capacitor and load; polarity marking ensures correct PCB orientation during assembly |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring overvoltage protection | Enhances reliability under line surges and ringing in discontinuous conduction mode (DCM) flyback converters |
| Moisture sensitivity level 1 | Eliminates bake requirement before SMT reflow, reducing manufacturing cost and cycle time |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH06FN-M3/45 | Same DO-214AB package, 60 V VRRM, but 0.67 V VF (typ) at 8 A - lower conduction loss, higher leakage (25 mA @ 100°C) | Better efficiency at light loads; less suitable for high-temperature environments due to higher IR | Select when thermal headroom is available and <1% efficiency gain justifies tighter leakage control |
| ON Semiconductor SB860-E3/54 | 60 V VRRM, 0.72 V VF (typ), but only rated to 125°C TJ max and RθJA = 25 °C/W | Limited to lower-power adapters (<45 W) due to reduced thermal performance and junction temperature ceiling | Prefer for cost-sensitive, lower-power consumer adapters where 150°C operation is not required |
Compared with VS-8EWH06FN-M3/45 and SB860-E3/54, the SK86C R7G delivers superior high-temperature reliability (150°C TJ), balanced VF/IR trade-off, and industry-leading 20 °C/W thermal resistance - making it optimal for thermally constrained, high-power-density industrial and automotive-grade power supplies.

FAQ
What is the maximum junction temperature rating for the SK86C R7G?
The SK86C R7G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version L2102). This allows continuous operation in high-ambient environments such as enclosed LED drivers or under-hood automotive modules. The SK86C R7G maintains specified electrical parameters up to this limit, provided thermal design respects the 20 °C/W RθJA value.
Does the SK86C R7G have a halogen-free construction?
Yes, the SK86C R7G uses halogen-free molding compound compliant with IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor SK82C–SK810C datasheet (Version L2102). This supports environmental compliance for export to EU, Japan, and other regulated markets, and eliminates corrosive gas generation during PCB rework or end-of-life incineration.
What is the forward voltage specification of the SK86C R7G at 8 A and 25°C?
The SK86C R7G has a typical forward voltage (VF) of 0.75 V at 8 A and 25°C, per the "ELECTRICAL SPECIFICATIONS" table in the official Taiwan Semiconductor datasheet (Version L2102). This value is measured under pulse test conditions (PW = 0.3 ms) and serves as the primary basis for conduction loss calculation in power supply thermal design.
Is the SK86C R7G suitable for use in RoHS-compliant assemblies?
Yes, the SK86C R7G is RoHS compliant and features matte tin-plated leads that meet J-STD-002 solderability requirements. Its halogen-free construction and lead-free compatibility are explicitly stated in the "Features" section of the Taiwan Semiconductor SK82C–SK810C datasheet (Version L2102), confirming suitability for fully RoHS-compliant manufacturing processes.
What packaging format is available for the SK86C R7G?
The SK86C R7G is supplied in DO-214AB (SMC) package on 3,000-piece tape-and-reel format, as specified in the "ORDERING INFORMATION" section of the Taiwan Semiconductor datasheet (Version L2102). The reel conforms to EIA-481 standards and supports high-speed pick-and-place assembly without manual handling or polarity errors.
