What the HJ8205 family does
The HJ8205 is an N-channel trench power MOSFET in the SOT-23-6L package. It features a 20 V drain-source voltage rating, 4.3 A continuous drain current, and less than 30 mΩ on-resistance at 4.0 V gate drive. The device includes a fast switching body diode capable of 1.7 A. Engineers typically use this component in battery-operated systems, load switches, and uninterruptible power supplies. It operates across a junction temperature range of -55 to +150 °C and meets RoHS compliance standards.
