In today's demanding automotive and power electronics markets, high-efficiency rectification with minimal forward voltage drop is critical. The SK810CHM6G Schottky diode from Taiwan Semiconductor Corporation meets these needs with its 100V/8A rating, AEC-Q101 qualification, and compact SMC packaging. As industries push for higher power density and reliability, this discontinued-but-still-relevant component offers a proven solution for designers seeking robust performance. Read on to explore its key parameters, applications, and alternatives to optimize your electronic component selection.
The SK810CHM6G is a surface-mount Schottky barrier diode housed in a DO-214AB (SMC) package, delivering:
High current capability: 8A average rectified current (Io)
Low forward voltage: 900mV max at 8A (reducing power loss)
Fast switching: Recovery time <500ns
Automotive-grade reliability: AEC-Q101 qualified for harsh environments
| Parameter | Value | Standard/Test Condition |
|---|---|---|
| Reverse Voltage (Vr) | 100V | Max DC |
| Forward Current (Io) | 8A | Average rectified |
| Forward Voltage (Vf) | 900mV max | @ 8A, 25°C |
| Reverse Leakage (Ir) | 500µA max | @ 100V, 25°C |
| Junction Temperature | -55°C to +150°C | Operating range |
| Package | DO-214AB (SMC) | Tape & Reel |
When choosing the SK810CHM6G or alternatives, consider:
Voltage requirements: Ensure Vr exceeds circuit needs by 20-30% margin
Current handling: Account for peak/average currents and thermal management
Switching speed: Fast recovery (<500ns) suits high-frequency apps
Environment: AEC-Q101 certification validates automotive use
| Model | Vr (V) | Io (A) | Vf @ Io | Package | Key Difference |
|---|---|---|---|---|---|
| SK810CHM6G | 100 | 8 | 900mV @8A | DO-214AB | Discontinued |
| SS8P6-M3/84A | 60 | 8 | 700mV @8A | DO-214AB | Lower Vr, better Vf |
| MBR8H100SFT3G | 100 | 8 | 850mV @8A | TO-277A | Active part, higher cost |
Used in:
DC-DC converters (12V/48V systems)
Reverse polarity protection
Alternator rectification
Benefits:
Low Vf improves efficiency in SMPS secondary-side rectification
Fast recovery reduces switching losses
According to industry reports:
Automotive Schottky diode market grows at 5.8% CAGR (2023-2030)
Demand for 60-100V diodes increases with 48V mild-hybrid systems
SMC packaging remains popular for space-constrained designs
While the SK810CHM6G is discontinued, its successor models will likely feature:
Lower Vf (SiC/GaN hybrid designs)
Higher temperature ratings (>175°C)
Improved surge current handling
Q1: Is the SK810CHM6G still recommended for new designs?
A: As a discontinued part, it's better to select active alternatives unless existing inventory is available.
Q2: What's the typical reverse recovery time?
A: <500ns per datasheet, making it suitable for switching frequencies up to ~100kHz.
Q3: Can this diode handle automotive load-dump pulses?
A: While AEC-Q101 qualified, verify against specific pulse requirements (ISO 7637-2).
Q4: What's the recommended PCB land pattern?
A: Follow IPC-7351B for DO-214AB (SMC) packages with adequate thermal relief.
Q5: How does its Vf compare to silicon diodes?
A: Schottky diodes typically offer 30-50% lower Vf than PN junction diodes at same current.
The SK810CHM6G exemplifies Taiwan Semiconductor's capability in automotive-grade Schottky diodes, balancing performance and packaging efficiency. While discontinued, its parameters set benchmarks for replacement selection. For current designs, consider newer AEC-Q101 diodes with similar specs but improved availability.
