Product details

Overview

SK810C R7G from Taiwan Semiconductor is an 8A, 100V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, designed for high-efficiency DC/DC conversion in switching power supplies, with 0.90V forward voltage at 8A and 150A surge capability.

For engineers reviewing the SK810C R7G datasheet, SK810C R7G pinout, SK810C R7G application, or SK810C R7G equivalent, key selection criteria include reverse voltage rating (100V), thermal resistance (20°C/W), junction temperature range (–55°C to +150°C), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.

Technical Context

This discrete Schottky diode uses a single-die construction optimized for low conduction loss in high-frequency SMPS topologies. Its 100V V_RRM, 150A I_FSM, and 10,000 V/µs dV/dt support robust operation under transient overvoltage and repetitive surge conditions.

The device features a guard ring structure for enhanced overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Thermal performance is characterized by R_θJA = 20°C/W, enabling reliable 8A continuous operation with appropriate PCB copper area.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse voltage before breakdown; defines upper limit for DC bus or output rail voltage handling
I_F	8 A - Continuous average forward current at T_A = 25°C; derates linearly above 25°C per forward current derating curve
I_FSM	150 A - Non-repetitive peak surge current (8.3 ms half-sine); supports inrush and fault-current tolerance in AC-DC front-ends
V_F	0.90 V @ 8A, 25°C - Low forward drop reduces conduction loss and improves system efficiency in high-current paths
R_θJA	20 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area and heatsinking for thermal management
T_J max	+150 °C - Maximum allowable junction temperature; enables operation in high-ambient industrial environments
MSL	Level 1 (per J-STD-020) - No floor life limitation; suitable for standard SMT reflow without dry-pack or baking requirements

Pinout & Package

Package: DO-214AB (SMC) - Surface-mount plastic case with cathode band marking; 0.210 g weight; UL 94V-0 rated molding compound; matte tin-plated leads.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side (e.g., switch node in buck converter or secondary winding in flyback)
Cathode	Forward current exit point	Marked by band; connected to higher-potential output rail or return path; carries full load current to ground or input

Key Features

Feature	Design Value
Guard ring structure	Enhances ruggedness against transient overvoltage events without requiring external snubbers
High surge current capability	150A I_FSM supports repeated cold-start and short-circuit stress in power adapters and LED drivers
Low forward voltage	0.90V at 8A minimizes power dissipation (7.2W) and simplifies thermal design vs. higher-V_F alternatives
Moisture sensitivity level 1	Enables direct placement from reel without dry storage or bake-out, reducing manufacturing overhead
Halogen-free & RoHS compliant	Meets IEC 61249-2-21 and EU RoHS Directive; supports green electronics manufacturing and export compliance

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-M3/45	Same DO-214AB package, 8A/100V, but V_F = 0.82V @ 8A; R_θJA = 22°C/W; MSL Level 1	Slightly lower V_F improves efficiency marginally; higher R_θJA requires larger copper area for same thermal performance	Preferred where ultra-low conduction loss dominates over thermal layout constraints
ON Semiconductor SB8100E	DO-214AB, 8A/100V, V_F = 0.92V @ 8A; I_FSM = 120A; R_θJA = 20°C/W; MSL Level 1	Lower surge rating (120A vs. 150A); identical thermal resistance and compliance profile	Valid alternative when surge stress is moderate and supply chain diversification is prioritized

Compared with VS-8EWH10FN-M3/45 and SB8100E, the SK810C R7G offers the highest surge current rating (150A) while matching the thermal resistance (20°C/W) of SB8100E and maintaining full MSL Level 1 handling-making it optimal for high-stress industrial and telecom rectification.

FAQ

What is the maximum junction temperature rating for SK810C R7G?

The SK810C R7G has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version L2102). This rating applies across the full operating range and enables use in high-ambient industrial environments where thermal headroom is critical. The SK810C R7G must be mounted on adequate PCB copper to maintain T_J ≤ 150°C under full 8A load.

Is SK810C R7G pin-compatible with other SK8xC series devices?

Yes, all SK8xC devices-including SK810C R7G-share identical DO-214AB (SMC) package dimensions, pinout (anode/cathode), polarity marking (cathode band), and mechanical footprint. Voltage variants (20V–100V) are mechanically interchangeable, though electrical substitution requires verification of V_RRM, V_F, and I_FSM for the target application.

What is the forward voltage of SK810C R7G at 8A and 100°C junction temperature?

The SK810C R7G forward voltage is not specified at 100°C in the official datasheet; only V_F = 0.90V @ 8A, 25°C and IR = 10 mA @ 100°C are provided. Forward voltage increases with temperature-typical curves show ~0.75–0.80V at 100°C for similar 100V Schottky diodes-but exact value for SK810C R7G requires interpolation from Fig.4 (Typical Forward Characteristics) in the datasheet.

Does SK810C R7G meet JESD201 whisker testing requirements?

Yes, the SK810C R7G meets JESD201 Class 2 whisker test requirements, as confirmed in the Mechanical Data section of the Taiwan Semiconductor datasheet. This ensures long-term reliability of matte tin-plated leads under thermal cycling and storage, preventing tin whisker growth that could cause latent short circuits in high-reliability applications.

What packaging and reel quantity is available for SK810C R7G?

The SK810C R7G is supplied in DO-214AB (SMC) package on tape-and-reel format, with 3,000 units per reel, consistent with the ordering information table in the Taiwan Semiconductor SK82C–SK810C datasheet (Version L2102). Reel specifications comply with EIA-481 standards for automated SMT placement.
