Product details
Overview
SK82C V6G from Taiwan Semiconductor is an 8A, 20V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching mode power supplies and adapters. It features low forward voltage (0.55 V at 8 A, 25°C), 150 A surge capability, 10,000 V/µs dV/dt rating, and junction temperature up to +125°C.
For engineers reviewing the SK82C V6G datasheet, SK82C V6G pinout, SK82C V6G application, or SK82C V6G equivalent, key selection criteria include repetitive peak reverse voltage (20 V), thermal resistance (20 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and cathode-band polarity marking.
Technical Context
The SK82C V6G implements a single-die Schottky barrier structure with guard ring overvoltage protection, enabling robust operation under transient conditions. Its low VF and high IFSM support high-frequency, high-current DC-DC conversion with minimal conduction loss.
Thermal performance is defined by RθJA = 20 °C/W and TJ max = +125°C, requiring adequate PCB copper area per DO-214AB pad layout. The device operates across -55°C to +125°C junction range and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Continuous Forward Current) | 8 A - supports sustained output current in compact SMPS designs without forced air cooling |
| VRRM (Repetitive Peak Reverse Voltage) | 20 V - suitable for low-voltage secondary-side rectification in 12 V and 5 V output rails |
| VF (Forward Voltage @ 8 A, 25°C) | 0.55 V - reduces conduction loss by ~30% vs. comparable 0.8 V Si diodes, improving efficiency |
| IFSM (Surge Current, 8.3 ms) | 150 A - withstands inrush and transient overload in AC-DC adapters and LED drivers |
| RθJA (Junction-to-Ambient) | 20 °C/W - requires ≥ 100 mm² of 2-oz copper on top layer for safe operation at full current |
| dV/dt (Critical Rate of Rise) | 10,000 V/µs - prevents false turn-on during fast-switching transitions in synchronous rectifier circuits |
| Moisture Sensitivity Level | Level 1 (per J-STD-020) - no baking required before reflow, compatible with standard SMT lines |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, matte tin-plated leads, cathode indicated by band. Weight: 0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Current entry point under forward bias | Connected to transformer secondary or switch node; must be routed with low-inductance trace |
| Cathode (Lead 2, banded end) | Current exit point under forward bias | Connected to output capacitor ground return; serves as reference for voltage sensing and feedback |
Key Features
| Feature | Design Value |
|---|---|

| Low VF at high IF | 0.55 V @ 8 A enables >92% efficiency in 12 V/5 A flyback outputs without heatsinking |
| J-STD-020 Level 1 MSL | Eliminates pre-bake step, reducing SMT line downtime and handling cost |
| UL 94V-0 molding compound | Meets flame-retardancy requirements for enclosed power adapters and lighting fixtures |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for global market access |
Applications
| AC-DC Adapters | LED Constant-Current Drivers |
|---|---|
Use Scenario: 12 V/3 A wall adapter for consumer electronics with <15 mm height constraint. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement, conducting during low-side MOSFET on-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-8EWH02FN-M3/45 | Same 8 A / 20 V rating, but TO-277 package (smaller footprint, higher RθJA = 25 °C/W) | Preferred where board space is constrained but thermal margin allows higher junction rise | Select when minimizing PCB area outweighs thermal derating needs |
| ON Semiconductor SB820-E3/45 | Identical DO-214AB package, but VF = 0.57 V (max) and IFSM = 120 A (lower surge tolerance) | Suitable for non-critical surge environments like low-cost consumer adapters | Choose when cost sensitivity dominates over peak-load robustness |
Compared with VS-8EWH02FN-M3/45 and SB820-E3/45, the SK82C V6G delivers superior surge immunity (150 A vs. 120–130 A) and lower thermal resistance (20 vs. 25 °C/W), making it preferred for industrial-grade 8 A rectification where reliability under transient stress is critical.

FAQ
What is the maximum junction temperature rating for the SK82C V6G?
The SK82C V6G has a maximum junction temperature (TJ) rating of +125°C, validated per absolute maximum ratings table in the L2102 datasheet. This allows continuous 8 A operation in ambient temperatures up to +85°C when mounted on a standard 2-layer PCB with ≥100 mm² of 2-oz copper per terminal. Exceeding +125°C risks irreversible degradation of the Schottky junction.
Does the SK82C V6G have a lead-free and halogen-free construction?
Yes, the SK82C V6G is RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound is UL 94V-0 rated. These attributes are confirmed in the Mechanical Data and Ordering Information sections of the L2102 datasheet.
What does the "V6G" suffix indicate in SK82C V6G?
The "V6G" suffix in SK82C V6G denotes Taiwan Semiconductor's internal revision and environmental code: "V6" indicates tape-and-reel packaging with 3,000 units per reel, and "G" signifies green (halogen-free) compound per IEC 61249-2-21. This coding aligns with TSC's standard ordering nomenclature documented in Version L2102.
Can the SK82C V6G replace the SK83C in a 30 V design?
No - the SK82C V6G is rated for 20 V VRRM only and must not be substituted for the SK83C (30 V) in circuits where reverse voltage exceeds 20 V. Doing so risks catastrophic failure due to avalanche breakdown. The SK82C V6G is strictly intended for ≤20 V applications such as 12 V output rails.
How is polarity marked on the SK82C V6G package?
Polarity is marked on the SK82C V6G via a distinct cathode band located at one end of the DO-214AB (SMC) body. Per the Marking Diagram in the L2102 datasheet, the banded end corresponds to the cathode terminal (Lead 2), while the unmarked end is the anode (Lead 1). This matches industry-standard SMC polarity convention.
