The 2N7002A-RTK/HS is a small signal N-Channel MOSFET manufactured by KEC. It's designed for low-voltage, low-current switching applications. The "-RTK/HS" likely refers to a specific tape and reel packaging configuration for automated assembly and potentially a specific binning or screening process.

Applications

• Low-Side Switching
• Logic Level Conversion
• Small Signal Amplification
• Relay Driving
• LED Driving

Features

• N-Channel MOSFET
• Low Threshold Voltage
• Fast Switching Speed
• Surface Mount Package (SOT-23 or similar)
• RoHS Compliant
• Tape and Reel Packaging (RTK/HS Indication)

Benefits

• Efficient Low-Voltage Switching due to low threshold voltage.
• Reduced Switching Losses due to fast switching speed.
• Compact Design suitable for space-constrained applications because of the small surface mount package.
