Product details
Overview
SK83C M6G from Taiwan Semiconductor is an 8A, 30V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, featuring low forward voltage (0.55 V at 8 A, 25°C), 150 A surge capability, and junction temperature rating up to +150°C. It serves as a primary output rectifier in high-efficiency AC/DC adapters and DC/DC converters.
For engineers reviewing the SK83C M6G datasheet, SK83C M6G pinout, SK83C M6G application, or SK83C M6G equivalent, key selection criteria include repetitive peak reverse voltage (30 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 SK83C M6G implements a single-die Schottky junction optimized for low conduction loss in medium-voltage switching power supplies. Its 30 V VRRM, 0.55 V typical forward voltage at 8 A, and 150 A non-repetitive surge current support high-frequency operation with minimal thermal stress.
Designed for surface-mount assembly on PCBs with JESD201 Class 2 whisker resistance and matte tin-plated leads, it operates across -55°C to +150°C junction temperature range and meets UL 94V-0 flammability requirements in its DO-214AB molded package.

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-8EWH03FN-M3/45 | Same DO-214AB package, 8 A/30 V, but VF = 0.52 V (typ) at 8 A; slightly lower leakage at 100°C (5 mA vs 15 mA) | Better efficiency in thermally limited LED drivers; tighter IR spec suits higher ambient environments | Preferred where <0.53 V VF is required and 5 mA IR ceiling is mandated at 100°C |
| ON Semiconductor SB830 | DO-214AB, 8 A/30 V, VF = 0.57 V (max) at 8 A; TJ max = +125°C (not +150°C); MSL Level 1 confirmed | Limited to lower-temperature industrial enclosures; less margin for thermal runaway in high-power density designs | Select when cost sensitivity outweighs 25°C junction headroom and 0.02 V VF penalty is acceptable |
Compared with VS-8EWH03FN-M3/45 and SB830, the SK83C M6G offers superior high-temperature capability (+150°C vs +125°C) and balanced VF/IR trade-off for mainstream adapter and converter use, while maintaining identical footprint and assembly compatibility.

FAQ
What is the maximum junction temperature rating for SK83C M6G?
The SK83C M6G 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 thermally demanding applications such as enclosed AC/DC adapters and industrial power modules where ambient temperatures exceed 85°C. The SK83C M6G maintains specified electrical performance up to this limit when thermal design respects its 20 °C/W RθJA.
Does SK83C M6G have a halogen-free and RoHS-compliant construction?
Yes, the SK83C M6G is both RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet. Its molding compound, lead finish (matte tin), and internal materials meet these environmental standards, making it suitable for consumer electronics and industrial equipment sold in EU, China, and other regulated markets.
What is the forward voltage of SK83C M6G at rated current and room temperature?
The typical forward voltage (VF) of the SK83C M6G is 0.55 V at 8 A and 25°C, per the "Electrical Specifications" table in the official datasheet. This value is measured under pulse conditions (PW = 0.3 ms) and represents a key efficiency parameter-lower VF directly reduces conduction loss and thermal load in high-current rectification stages.
Is SK83C M6G suitable for automated SMT placement?
Yes, the SK83C M6G is explicitly designed for automated placement, as noted in its "Features" list. Its DO-214AB (SMC) package, gull-wing lead form, matte tin plating (solderable per J-STD-002), and J-STD-020 Level 1 moisture sensitivity enable robust, high-yield reflow assembly without baking or special handling-ideal for high-volume adapter and lighting production lines.
What does the "M6G" suffix indicate in SK83C M6G?
The "M6G" suffix in SK83C M6G denotes Taiwan Semiconductor's internal packaging and environmental coding: "M" indicates tape-and-reel packaging (3,000 pcs/reel), "6" specifies green molding compound (halogen-free), and "G" confirms RoHS compliance. This matches the ordering information table in the SK82C–SK810C datasheet (Version L2102), confirming full regulatory and mechanical alignment with the base SK83C device.
