On a lot of projects I often use an IRLML6402 P Channel MOSFET to switch VCC to devices, so as to turn them on and off.
The IRLML6402 has an RDS(on) of 0.08 ohm typical, a gate threshold of 0.55v and a drain current of 2A or so. It works well in 3.3V powered projects. Its a surface mount device.
Does anyone know of a TO92 packaged MOSFET that would do as a replacement, it only needs to handle 250mA or so.
A parameter search at Farnell\Element14 was not successful.
