Product details
Overview
SK510C R6G from Taiwan Semiconductor is a 5A, 100V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching power supplies with low forward voltage (0.85 V at 5 A, 25°C) and high surge capability (120 A IFSM). It features guard ring overvoltage protection, moisture sensitivity level 1, and RoHS/halogen-free compliance.
For engineers reviewing the SK510C R6G datasheet, SK510C R6G pinout, SK510C R6G application, or SK510C R6G equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 0.3 mA max reverse leakage at 25°C, junction-to-lead thermal resistance of 13°C/W, and suitability for compact, thermally constrained SMPS and adapter designs.
Technical Context
The SK510C R6G implements a single-die Schottky structure with metal-semiconductor junction enabling fast recovery (no minority carrier storage) and low conduction loss. Its 100 V VRRM rating targets mid-voltage DC-DC conversion stages where efficiency and thermal management are critical.
Thermal performance is defined by RθJL = 13°C/W on a 16 mm × 16 mm PCB copper pad, supporting continuous 5 A operation up to 150°C junction temperature. The cathode band polarity marking and matte tin-plated leads ensure reliable automated assembly per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; sets upper limit for output rectification in 12–48 V input SMPS secondary side |
| IF | 5 A - Continuous forward current rating; supports typical 60–100 W adapter output stages |
| VF @ 5 A, 25°C | 0.85 V - Low conduction loss reduces heat generation and improves system efficiency vs. silicon diodes |
| IR @ 100 V, 25°C | 0.3 mA - Low leakage preserves standby power budget in energy-efficient designs |
| IFSM (8.3 ms) | 120 A - Withstands inrush and transient surges without failure during startup or fault conditions |
| RθJL | 13 °C/W - Enables direct thermal coupling to PCB copper, simplifying heatsinking in space-constrained layouts |
| TJ max | 150 °C - Allows operation in high-ambient environments such as enclosed LED drivers or industrial adapters |
Pinout & 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-50WQ10FN-M3/45 | Same 100 V VRRM, 5 A IF, but TO-220AC package; higher RθJA (40°C/W), no SMC footprint | Requires through-hole mounting and heatsink; unsuitable for ultra-thin adapters | Select only when board-level thermal mass is insufficient for SMC package or legacy TO-220 layout reuse is required |
| ON Semiconductor SB5100-E3/54 | Same DO-214AB package, 100 V VRRM, but VF = 0.82 V (typ) at 5 A; IR = 0.5 mA (max) at 25°C | Slightly lower conduction loss but higher leakage; may impact light-load efficiency in energy-star designs | Prefer for lowest VF priority; verify IR impact on standby power if <30 mW target exists |
Compared with VS-50WQ10FN-M3/45 and SB5100-E3/54, the SK510C R6G delivers optimal balance of low VF (0.85 V), ultra-low IR (0.3 mA), and SMC package thermal performance (RθJL = 13°C/W), making it especially suitable for space- and efficiency-critical adapter and LED driver designs.

FAQ
What is the maximum junction temperature rating for the SK510C R6G?
The SK510C R6G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision S2311. This rating allows sustained operation in thermally demanding environments such as enclosed LED drivers or industrial power modules, provided PCB thermal design meets the specified 16 mm × 16 mm copper pad requirement for RθJL = 13°C/W. The SK510C R6G must not be operated beyond this limit to ensure reliability.
Does the SK510C R6G have a lead-free and RoHS-compliant construction?
Yes, the SK510C R6G is RoHS compliant and halogen-free, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet (S2311). Its matte tin-plated leads meet J-STD-002 solderability standards, and the molding compound satisfies UL 94V-0 flammability requirements. These attributes make the SK510C R6G suitable for environmentally regulated end equipment including consumer electronics and industrial controls sold in EU and other RoHS-enforced markets.
What is the forward voltage drop of the SK510C R6G at rated current?
The SK510C R6G exhibits a maximum forward voltage (VF) of 0.85 V at 5 A forward current and 25°C junction temperature, per the "ELECTRICAL SPECIFICATIONS" table in the official datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated temperatures (e.g., 125°C), VF decreases slightly due to Schottky junction characteristics, but system-level thermal design must still account for worst-case conduction loss using the 25°C spec.
Is the SK510C R6G suitable for use in high-surge applications like AC-DC adapter startup?
Yes, the SK510C R6G supports a non-repetitive peak forward surge current (IFSM) of 120 A for an 8.3 ms half-sine waveform, as confirmed in the "ABSOLUTE MAXIMUM RATINGS" table. This capability enables robust handling of inrush currents during cold-start conditions in universal-input AC-DC adapters, eliminating the need for external surge-limiting resistors or NTC thermistors in many designs. The SK510C R6G's guard ring structure further enhances transient voltage ruggedness.
What package type does the SK510C R6G use, and what are its key mechanical features?
The SK510C R6G uses the DO-214AB (SMC) surface-mount package, with dimensions matching JEDEC standard variation AB. Key mechanical features include a 16 mm × 16 mm copper pad footprint for thermal performance validation, cathode polarity indicated by a molded band, matte tin-plated leads for solderability, and a UL 94V-0 rated molding compound. Its weight is approximately 0.210 g, and it meets JESD201 Class 2 whisker resistance requirements.
