Product details

900 V N-channel in an IPAK — the switching load you can fit in tight spaces

On-resistance and drive voltage — where the conduction loss lands

Gate threshold voltage is 5 V maximum at 100 µA drain current, so the device is fully enhanced only when the gate-source voltage exceeds that threshold by several volts.

The IPAK (TO-251) package has three leads on a 2.54 mm pitch, with the centre tab as the drain. It is a through-hole part, so it stands off the board and can be heatsunk via the tab to the PCB copper or an external clip. The package case code is TO-251-3 Long Leads, IPak, TO-251AB — the long-lead variant gives extra stand-off height for cleaning under the part.
