Product details
Overview
SK810CH from Taiwan Semiconductor is a 100V, 8A surface-mount Schottky barrier rectifier in DO-214AB (SMC) package, featuring 0.90V forward voltage at 8A/25°C, 150A surge capability, AEC-Q101 qualification, and guard ring for over-voltage protection-used in automotive reverse battery protection and DC/DC converters.
For engineers reviewing the SK810CH datasheet, SK810CH pinout, SK810CH application, or SK810CH equivalent, key selection criteria include peak reverse voltage (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 Schottky rectifier uses a single-die construction with platinum-silicide or similar low-barrier metallization to achieve fast switching and low VF. Its 100V VRRM rating targets mid-range automotive and industrial power conversion where higher blocking voltage is required without sacrificing efficiency.
The device operates up to +150°C junction temperature and exhibits 10 mA reverse leakage at rated VR and 100°C, enabling reliable freewheeling in high-temperature engine-bay environments. Its 10,000 V/µs dV/dt rating supports robust operation in noisy inverter and SMPS circuits.
Key Specifications

| VF @ 8A, 25°C | 0.90 V - forward conduction loss directly impacts system efficiency and thermal design |
| IFSM | 150 A - non-repetitive surge current handling for startup/load dump events |
| RθJA | 20 °C/W - junction-to-ambient thermal resistance defines heatsinking requirements on standard FR-4 |

FAQ
What is the maximum junction temperature rating for SK810CH?
The SK810CH has a maximum junction temperature (TJ max) of +150°C, verified per AEC-Q101 stress testing. This allows operation in under-hood automotive environments where ambient temperatures exceed 105°C. The device's thermal resistance (RθJA = 20°C/W) and 100V blocking capability make SK810CH suitable for sustained high-power dissipation when properly mounted on copper pour. Always refer to the derating curve in the SK810CH datasheet for current limits above 25°C ambient.
Is SK810CH pin-compatible with other SK8xCH variants like SK86CH?
Yes, all SK8xCH devices-including SK810CH, SK86CH, and SK82CH-share identical DO-214AB (SMC) package dimensions, pinout, and terminal configuration (anode/cathode). However, electrical parameters differ: SK810CH is rated for 100V VRRM and 0.90V VF, whereas SK86CH is 60V/0.75V. Substitution requires verification of voltage margin and thermal performance in the target application. SK810CH cannot be replaced by lower-VRRM variants in 100V systems.
Does SK810CH require special handling due to moisture sensitivity?
No-SK810CH is rated J-STD-020 Level 1, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without baking. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94V-0 molding compound ensures flame resistance. This eliminates moisture-related popcorning risk and simplifies manufacturing for SK810CH in high-volume SMT lines.
What is the reverse leakage current specification for SK810CH at elevated temperature?
At rated 100V reverse voltage and TJ = 100°C, SK810CH specifies a maximum reverse leakage current (IR) of 10 mA-measured per pulse test (PW = 30 ms). This value is critical for standby power budgeting in always-on automotive modules. At 25°C and 100V, IR is limited to 0.5 mA. These values are confirmed in the Electrical Specifications table of the official SK810CH datasheet (Version A2102).
How does the guard ring feature improve reliability of SK810CH?
The guard ring in SK810CH mitigates edge breakdown under high dV/dt stress (rated 10,000 V/µs), preventing premature failure during voltage transients such as load dump or inductive switching. It enhances field distribution at the die periphery, allowing SK810CH to sustain 100V blocking with higher ruggedness than non-guarded Schottky diodes. This feature directly supports AEC-Q101 qualification and is essential for reverse battery protection and freewheeling roles in harsh automotive environments.
