Product details

Overview

SK810C from Taiwan Semiconductor is a 100 V, 8 A surface-mount Schottky barrier rectifier in DO-214AB (SMC) package, featuring 0.90 V forward voltage at 8 A and 10 mA reverse leakage at 100 V and 100°C, optimized for high-efficiency switching mode power supplies and DC-DC converters.

For engineers reviewing the SK810C datasheet, SK810C pinout, SK810C application, or SK810C equivalent, key selection criteria include repetitive peak reverse voltage (100 V), surge current rating (150 A), thermal resistance (20 °C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance.

Technical Context

The SK810C employs a single-die Schottky structure with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 100 V V_RRM and 150 A I_FSM support robust transient handling in high-frequency switching topologies.

Thermal performance is defined by a junction-to-ambient thermal resistance of 20 °C/W and maximum junction temperature of +150°C, enabling operation in compact, convection-cooled power stages without forced airflow.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse blocking voltage; sets upper limit for input/output rail isolation in buck/boost converters.
I_F	8 A - Continuous forward current rating; defines steady-state power delivery capability at rated case temperature.
I_FSM	150 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance in AC/DC front-ends.
V_F @ 8 A, 25°C	0.90 V - Forward voltage drop; directly determines conduction loss (P_cond ≈ 7.2 W at 8 A) and thermal load.
I_R @ 100 V, 100°C	10 mA - High-temperature reverse leakage; impacts standby power and thermal runaway risk in parallel configurations.
R_θJA	20 °C/W - Junction-to-ambient thermal resistance; enables ~7.5 W max dissipation at ΔT = 150°C in standard SMC layout on 1 oz Cu.
T_J max	+150°C - Maximum junction temperature; allows extended operation in industrial ambient (e.g., 85°C) with sufficient margin.

Pinout & Package

Package: DO-214AB (SMC), surface-mount, cathode indicated by band, moisture sensitivity level 1 per J-STD-020, weight ≈ 0.210 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential node (e.g., switch node in synchronous rectification); requires low-inductance trace routing.
Cathode	Forward current exit / reverse blocking terminal	Connected to output rail or ground return; cathode band marking ensures correct PCB polarity alignment during automated placement.

Key Features

Feature	Design Value

150 A surge rating	Withstands repeated cold-start surges in 100–240 VAC adapters without derating or parallel devices.
Halogen-free & RoHS compliant	Meets IEC 61249-2-21 and EU RoHS directives, supporting green manufacturing and export compliance for global OEMs.
J-STD-002 solderable leads	Ensures reliable reflow joint formation in lead-free (SAC305) processes without voiding or dewetting issues.

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-8EWH10FN-M3	100 V, 8 A, V_F = 0.82 V @ 8 A, 25°C; R_θJA = 25 °C/W; DO-214AB package.	Lower V_F improves light-load efficiency but higher thermal resistance limits power density in compact layouts.	Preferred where ultra-low conduction loss dominates over thermal footprint constraints.
ON Semiconductor SB8100	100 V, 8 A, V_F = 0.95 V @ 8 A, 25°C; I_R = 12 mA @ 100 V, 125°C; DO-214AB package.	Slightly higher leakage and V_F increase conduction loss and standby power vs. SK810C.	Valid alternative when sourcing diversity is required and 5% efficiency penalty is acceptable.

Compared with VS-8EWH10FN-M3 and SB8100, the SK810C delivers optimal balance of low V_F (0.90 V), tight thermal resistance (20 °C/W), and low high-temp leakage (10 mA), making it especially suitable for space-constrained, high-ambient industrial converters where thermal management and standby loss are critical.

FAQ

What is the maximum junction temperature rating for the SK810C?

The SK810C has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version L2102). This allows operation in industrial environments up to 85°C ambient with appropriate PCB copper area, and confirms suitability for applications requiring extended thermal margin beyond standard 125°C-rated devices. The SK810C maintains full electrical specifications within this range.

Does the SK810C have a guard ring structure, and what is its function?

Yes, the SK810C incorporates a guard ring structure explicitly stated in its features list. This design enhances edge termination robustness, improving resistance to transient overvoltage events such as line surges or inductive kickback without requiring external snubber networks. In practical use, this increases reliability in flyback and resonant converter topologies where voltage overshoot is common, and is confirmed in the "FEATURES" section of the SK82C–SK810C datasheet.

What is the forward voltage of the SK810C at 8 A and 25°C?

The forward voltage (V_F) of the SK810C is 0.90 V at 8 A and 25°C, as specified in the "ELECTRICAL SPECIFICATIONS" table under "Forward voltage(1)" for SK810C. This value is measured using a pulse test with 0.3 ms pulse width and is critical for calculating conduction losses in power stage design. It is higher than lower-voltage SK8xC variants due to increased barrier height for 100 V rating.

Is the SK810C RoHS and halogen-free compliant?

Yes, the SK810C is RoHS compliant and halogen-free according to IEC 61249-2-21, as documented in the "FEATURES" section of the official Taiwan Semiconductor datasheet. This compliance applies to all materials including molding compound and lead finish, and is verified for production lots. The SK810C meets environmental requirements for global commercial and industrial electronics without requiring special handling or exemptions.

What is the surge current rating of the SK810C, and how is it defined?

The SK810C has a surge peak forward current (I_FSM) rating of 150 A, defined for an 8.3 ms single half-sine wave superimposed on rated load, per the "ABSOLUTE MAXIMUM RATINGS" table. This rating reflects short-duration overload capability during power-up or fault conditions and is validated through standardized JEDEC testing. It is identical across the SK8xC family and enables robust design in AC/DC adapters and server PSUs without additional parallel devices.
