BUK206-50X is an overload protected power switch based on MOSFET technology, with features such as low on-state resistance and 5V logic compatible input. It can be used for driving lamps, motors, solenoids, and heaters.
The document describes the BUK206-50X, an SMD version of the BUK202-50X. It is a vertical power DMOS switch configured as a single high side switch in a 5-pin plastic surface mount envelope (SOT426). The device features monolithic temperature and overload protection based on MOSFET technology.
| Nominal load current (ISO) | 9 A |
|---|---|
| Continuous off-state supply voltage | 50 V |
| Continuous load current | 20 A |
| Continuous junction temperature | 150 °C |
| On-state resistance (typical) | 38 mΩ |
The device supports a maximum continuous off-state supply voltage of 50 V.
When the load is open, the status output goes low while the switch remains in the on state.
The input voltage must be toggled low for the switch to resume normal operation.
