Product details
Overview
SK83C R7G from Taiwan Semiconductor is a 30V, 8A Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, featuring low forward voltage (0.55 V at 8 A, 25°C), high surge current capability (150 A), and junction temperature rating up to +150°C. It is used in high-efficiency switching mode power supplies and DC-DC converters where fast recovery and minimal conduction loss are critical.
For engineers reviewing the SK83C R7G datasheet, SK83C R7G pinout, SK83C R7G application, or SK83C R7G equivalent, key selection factors include its 30 V repetitive peak reverse voltage, 0.55 V forward voltage at rated current, 150 A surge rating, thermal resistance of 20 °C/W, and DO-214AB mechanical compatibility with automated SMT assembly.
Technical Context
The SK83C R7G employs a single-die Schottky junction optimized for low VF and high IFSM, enabling efficient operation in high-frequency SMPS topologies. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability requirements.
Rated for TJ = –55°C to +150°C and moisture sensitivity level 1 (per J-STD-020), it supports reflow-compatible assembly without baking. Reverse leakage is limited to 0.5 mA at 25°C and 15 mA at 100°C under rated VR, ensuring stable blocking performance across operating temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage the device blocks reliably in circuit |
| IF | 8 A - Continuous average forward current rating at TC = 110°C (derates above) |
| VF @ 8 A, 25°C | 0.55 V - Low conduction loss directly reduces power dissipation and improves system efficiency |
| IFSM | 150 A - Withstands short-duration inrush/surge currents without failure |
| RθJA | 20 °C/W - Thermal resistance from junction to ambient, defines heatsinking requirement for 8 A operation |
| TJ max | +150 °C - Maximum allowable junction temperature, enables high-temperature ambient deployment |
| IR @ VR, 25°C | 0.5 mA - Low reverse leakage preserves efficiency in high-impedance bias networks |

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 | Same DO-214AB package, 30 V VRRM, but VF = 0.49 V @ 8 A (lower), IR = 0.35 mA @ 25°C (lower) | Better efficiency at light loads; tighter IR spec suits precision bias rails | Preferred when <0.5 V VF or sub-0.4 mA IR is required; same footprint and thermal profile |
| ON Semiconductor SB830 | DO-214AB, 30 V VRRM, VF = 0.57 V @ 8 A, IFSM = 125 A (lower), TJ max = +125°C (lower) | Lower surge and temperature capability limits use in high-reliability or high-ambient designs | Acceptable for cost-sensitive consumer adapters where 125°C TJ and 125 A surge suffice |
Compared with VS-8EWH03FN-M3, SK83C R7G trades slightly higher VF for broader temperature range (+150°C vs. +125°C) and higher surge rating (150 A vs. 125 A); versus SB830, it delivers superior thermal robustness and surge margin at identical cost tier.

FAQ
What is the maximum junction temperature rating for SK83C R7G?
The SK83C R7G has a maximum junction temperature (TJ max) of +150°C, allowing reliable operation in enclosed or high-ambient-temperature environments such as industrial power modules and sealed LED drivers. This rating is confirmed in the Absolute Maximum Ratings table of the official TSC SK82C–SK810C datasheet (Version L2102), and exceeds the +125°C limit of many competing 30 V Schottky rectifiers like the SB830.
Does SK83C R7G have a halogen-free construction?
Yes, SK83C R7G is halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the TSC datasheet. This ensures compliance with environmental regulations including EU RoHS and supports safer end-of-life processing without release of toxic halogenated gases during recycling or incineration.
What is the forward voltage of SK83C R7G at 8 A and 25°C?
The forward voltage (VF) of SK83C R7G is 0.55 V at IF = 8 A and TJ = 25°C, per the Electrical Specifications table in the TSC datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and represents a key efficiency parameter-lower than SK84C (0.55 V) and significantly lower than SK85C (0.75 V) in the same family.
Is SK83C R7G suitable for automated SMT placement?
Yes, SK83C R7G is explicitly designed for automated placement, as noted in the FEATURES section of the TSC datasheet. Its DO-214AB (SMC) package, matte tin-plated leads compliant with J-STD-002, and moisture sensitivity level 1 (per J-STD-020) eliminate pre-baking and ensure robust solder joint formation in standard reflow profiles.
What does the "R7G" suffix indicate in SK83C R7G?
The "R7G" suffix in SK83C R7G denotes tape-and-reel packaging (R7 = 3,000 pcs/reel per TSC ordering code convention) and green molding compound (G = halogen-free, RoHS-compliant encapsulant). This matches the "PACKAGE" and "ORDERING INFORMATION" sections of the TSC SK82C–SK810C datasheet, confirming full compliance with environmental and logistics requirements.
