Product details
Overview
SK82C from Taiwan Semiconductor is an 8A, 20V 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 +125°C. It serves as a primary output rectifier in compact AC/DC adapters and high-efficiency DC-DC converters.
For engineers reviewing the SK82C datasheet, SK82C pinout, SK82C application, or SK82C equivalent, key selection criteria include its 20 V repetitive peak reverse voltage, 20 °C/W junction-to-ambient thermal resistance, moisture sensitivity level 1 compliance, and cathode-band polarity marking for reliable automated assembly.
Technical Context
The SK82C employs a single-die Schottky junction optimized for low conduction loss in medium-voltage switching power supplies. Its 0.55 V forward voltage at 8 A and 25°C directly reduces power dissipation versus silicon diodes, while the 150 A non-repetitive surge rating supports transient load conditions in SMPS designs.
Thermally, the DO-214AB (SMC) package delivers 20 °C/W RθJA, enabling operation up to 125°C junction temperature without forced cooling. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards, supporting robust industrial and consumer-grade board assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 8 A continuous - supports high-current secondary-side rectification in 30–60 W adapters |
| Repetitive Peak Reverse Voltage (VRRM) | 20 V - suitable for 12 V output rails with margin against voltage spikes |
| Forward Voltage (VF) | 0.55 V @ 8 A, 25°C - reduces conduction loss by ~40% vs. comparable silicon diodes |
| Surge Current (IFSM) | 150 A @ 8.3 ms - withstands inrush and short-circuit transients in SMPS |
| Junction Temperature (TJ) | –55°C to +125°C - enables operation in sealed enclosures without active cooling |
| Thermal Resistance (RθJA) | 20 °C/W - allows 4.5 W power dissipation with ≤100°C ambient under standard PCB layout |
| Moisture Sensitivity Level | Level 1 per J-STD-020 - no bake required before reflow, simplifying SMT line handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS82P-E3/5AT (Vishay) | Same 20 V VRRM, 8 A IF, but VF = 0.57 V @ 8 A; RθJA = 22 °C/W | Slightly higher thermal resistance requires larger copper area for same power dissipation | Preferred where Vishay's qualification history in automotive-grade modules is required |
| MBR820G (ON Semiconductor) | 20 V VRRM, 8 A IF, VF = 0.54 V @ 8 A; DO-214AB package; TJ max = 125°C | Nearly identical electrical and thermal specs; minor VF advantage of 0.01 V | Drop-in alternative when ON Semi's supply chain continuity is prioritized |
Compared with SS82P-E3/5AT and MBR820G, the SK82C offers identical voltage/current ratings and industry-standard DO-214AB footprint, with a balanced trade-off between VF (0.55 V), thermal resistance (20 °C/W), and cost-effective green compound packaging.

Manufacturer
Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global power electronics markets since 1979.

FAQ
What is the maximum junction temperature rating for the SK82C?
The SK82C has a maximum junction temperature (TJ) rating of +125°C. This specification is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2102). Operation beyond this limit risks irreversible degradation of the Schottky junction. Derating curves in Figure 1 show that continuous 8 A current is sustainable only up to ~70°C ambient when using standard PCB copper area, due to its 20 °C/W RθJA.
Does the SK82C have a halogen-free construction?
Yes, the SK82C is halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This applies to the molding compound and ensures compliance with environmental directives for consumer and industrial electronics. The "G" in the part marking "SK82C M6G" denotes green compound, confirming halogen-free status per TSC's internal coding.
What does the "M6G" suffix mean in SK82C M6G?
The "M6G" suffix in SK82C M6G identifies a specific manufacturing variant: "M6" indicates a date code (e.g., week 6 of year 202X), and "G" confirms halogen-free green compound per IEC 61249-2-21. This coding aligns with TSC's marking diagram on page 5 of the SK82C–SK810C datasheet (Version L2102). No electrical or thermal parameter differences exist between M6G and other SK82C variants.
Is the SK82C suitable for use in automotive applications?
No, the SK82C is not qualified for automotive applications. Taiwan Semiconductor explicitly states in the Notice section (page 6) that "The products shown herein are not designed for use in medical, life-saving, or life-sustaining applications." It lacks AEC-Q101 qualification, extended temperature range beyond +125°C, and automotive-specific reliability testing. For automotive 12 V systems, consider AEC-Q101-rated alternatives like STPS820CB-TR.
What is the moisture sensitivity level (MSL) of the SK82C?
The SK82C has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, as documented in the FEATURES section. This means the device may be stored indefinitely at ≤30°C/60% RH and requires no baking prior to reflow soldering. Level 1 is the least stringent MSL rating and reflects the robustness of its DO-214AB (SMC) package and green molding compound.
