complementary transistors needed

[sss]

hello

i need power mosfets to make an H bridge for switching pupose
specs needed
Vds>14V
Ids>30A
P>50W
i found only N channel types ,no complementary p channel.
does someone know any complementary pair with those specs?
thanx

Why do you want P-channel devices to make an H-bridge, for a "switcher"? There must be areason why all the commercial H-bridges out there all N-channel.

Reason for N-channel

I think the reason is that the on resistance (often) is lower for N-Channel types than for P's.

For a bridge I think you really only need on type.
