PHILIPS Buk130-50DL Data Sheet User Manual
Summary
This datasheet describes the Philips BUK130-50DL logic level TOPFET, a monolithic temperature and overload-protected power MOSFET in TOPFET2 technology assembled in a 3-pin SOT404 surface-mount plastic package. The device is an SMD version of the BUK119-50DL, rated for 50V continuous drain-source voltage and 20A continuous drain current (self-limited at 25°C) with 28mΩ maximum on-state resistance. Total power dissipation is 90W at 25°C mounting base temperature. The TrenchMOS output stage featur

Frequently Asked Questions
What voltage range controls the TOPFET's output stage?
The control logic requires a drain source voltage (V DS) between 4 V and 5.5 V to operate correctly.
Is this device safe for use in life support equipment?
No, the product specification warns that these devices are not designed for use in life support appliances or systems.
How does the TOPFET protect against overheating?
It features overload protection and an overtemperature trip point (T(TO)) to safeguard the switch from excessive heat.
