Product details
Overview
SK85C V6G from Taiwan Semiconductor is an 8A, 50V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, featuring 0.75V forward voltage at 8A/25°C, 150A surge capability, and 10,000 V/µs dV/dt rating-used in high-efficiency AC/DC adapters and DC/DC converters.
For engineers reviewing the SK85C V6G datasheet, SK85C V6G pinout, SK85C V6G application, or SK85C V6G equivalent, key selection criteria include its 50V VRRM rating, thermal resistance of 20°C/W, junction temperature range up to +150°C, and RoHS/halogen-free compliance for industrial power supply designs.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its low VF enables reduced conduction loss in high-frequency switching topologies.
Rated for 8A average forward current and 150A non-repetitive surge (8.3ms half-sine), it operates across –55°C to +150°C junction temperature, with reverse leakage limited to 0.5mA at 25°C and 10mA at 100°C under rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines usable input voltage headroom in buck or flyback secondary-side rectification |
| IF(AV) | 8 A - Continuous DC forward current rating at TC = 110°C; determines heatsink sizing in sustained-load applications |
| VF @ 8A, 25°C | 0.75 V - Forward voltage drop; directly impacts conduction loss (Pcond ≈ IF × VF) and thermal design |
| IFSM | 150 A - Peak non-repetitive surge current; supports inrush tolerance during cold-start in SMPS |
| RθJA | 20 °C/W - Junction-to-ambient thermal resistance; used with power dissipation to estimate worst-case TJ rise on PCB without heatsink |
| TJ max | +150 °C - Maximum allowable junction temperature; sets upper limit for thermal derating curves and reliability margin |
| dV/dt | 10,000 V/µs - Critical rate of rise of off-state voltage; ensures stability against false turn-on in fast-switching circuits |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode-indicated by band, matte tin-plated leads, moisture sensitivity level 1 (per J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node return path) |
| Cathode | Forward current exit point | Connected to output rail; polarity marked by visible band on body; must align with PCB silkscreen |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances ruggedness against transient overvoltage events without external snubbers |
| Low VF at high IF | 0.75 V @ 8A reduces conduction loss by ~20% vs. comparable 60V Schottkys, improving efficiency in 12–24V output supplies |
| High IFSM | 150 A surge rating supports >10× nominal current for short durations, enabling robust startup in high-capacitance-output converters |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive; suitable for export-constrained industrial and consumer end equipment |
Applications
| AC/DC Adapters | DC/DC Converters |
|---|---|
Use Scenario: 12V/5A wall adapter for networking equipment with 65kHz flyback topology. IC Role / Device Role / Timing Role: Secondary-side synchronous rectification replacement; handles 8A continuous output current with minimal voltage drop. Use Value: 0.75V VF reduces rectifier loss to <6W, lowering thermal stress and enabling compact enclosure design. | Use Scenario: Isolated 48V-to-12V telecom intermediate bus converter operating at 300kHz. IC Role / Device Role / Timing Role: Output rectifier in active-clamp forward or LLC resonant secondary stage. Use Value: 10,000 V/µs dV/dt rating prevents spurious conduction during fast voltage transitions in high-frequency operation. |
| LED Drivers | Industrial Power Supplies |
Use Scenario: Constant-current LED driver for street lighting with 36V output and 700mA–3A adjustable range. IC Role / Device Role / Timing Role: Output rectifier in boost-derived SEPIC or Cuk topology powering multi-string LEDs. Use Value: +150°C TJ max allows reliable operation in sealed, thermally constrained outdoor enclosures. | Use Scenario: 24V/10A DIN-rail power supply for PLC I/O modules with wide ambient (-25°C to +70°C). IC Role / Device Role / Timing Role: Main output rectifier in dual-switch forward converter with active reset. Use Value: 20°C/W RθJA enables direct PCB copper pour cooling-no heatsink required at full load below 50°C ambient. |
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-8EWH05FN-M3/45 | Same DO-214AB package, 8A/50V, VF = 0.71V @ 8A, IR = 0.45mA @ 25°C | Slightly lower VF and IR; tighter parametric distribution per lot | Preferred where ultra-low leakage or tighter VF binning is required in medical-grade adapters |
| ON Semiconductor SB850 | DO-214AB, 8A/50V, VF = 0.78V @ 8A, IR = 0.6mA @ 25°C, TJ max = +150°C | Near-identical ratings; different thermal impedance (RθJA = 22°C/W) | Valid alternative when sourcing flexibility is prioritized and 2°C/W RθJA difference is accommodated in layout |
Compared with SK85C V6G, VS-8EWH05FN-M3/45 offers marginally better conduction and leakage specs, while SB850 trades slightly higher VF and thermal resistance for broader global distribution-both require no PCB redesign but may need minor thermal validation.

FAQ
What is the maximum junction temperature rating for SK85C V6G?
The SK85C V6G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet revision L2102. This rating applies under steady-state conditions with appropriate thermal management and allows operation in high-ambient environments such as enclosed LED drivers or industrial DIN-rail supplies. The SK85C V6G must not exceed this limit to ensure reliability and parametric stability.
Does SK85C V6G have a halogen-free construction?
Yes, SK85C V6G is halogen-free in accordance with IEC 61249-2-21 and RoHS compliant, as confirmed in the "Features" section of the TSC SK82C–SK810C datasheet (Version L2102). The molding compound and plating meet environmental compliance requirements for export to EU, Japan, and other regulated markets. This specification applies directly to the SK85C V6G variant.
What is the forward voltage of SK85C V6G at 8A and 25°C?
The forward voltage (VF) of SK85C V6G is 0.75 V at 8A and TJ = 25°C, per the "ELECTRICAL SPECIFICATIONS" table in the TSC datasheet (Version L2102). This value is measured under pulse test conditions (PW = 0.3ms) and represents typical conduction loss behavior. The SK85C V6G maintains this VF performance across its defined operating range without requiring external bias or control.
Is SK85C V6G compatible with lead-free reflow soldering processes?
Yes, SK85C V6G features matte tin-plated leads that are solderable per J-STD-002 and rated for lead-free reflow profiles. Its moisture sensitivity level is Level 1 (per J-STD-020), meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. The SK85C V6G is fully compatible with standard IPC-7095-compliant SMT lines.
What does the "V6G" suffix indicate in SK85C V6G?
The "V6G" suffix in SK85C V6G denotes Taiwan Semiconductor's internal packaging and environmental coding: "V" indicates tape-and-reel packaging (3,000 pcs/reel), "6" specifies green compound (halogen-free), and "G" confirms RoHS compliance. This marking is consistent across TSC's SK8xC family and appears in the "ORDERING INFORMATION" section of the datasheet.
