Do you mean complimentary or a dual device like a 2SK389?

For complimentary the 2SJ164/2SK1104 from Panasonic might be the closest thing.

  J164  K1104
VGDS 65V  -65V
ID  -20mA  20mA
PD  300mW 300mW
Yfs 2.5mS 2.5mS
Ciss 10pF  7pF
Coss 3pF  1p3F
Crss 3pF  1p5F 

IDSS comes in five ranges

0.2 > 1 0.6 > 1.5 1 > 3 2.5 > 6 

The data sheet has no info on noise just says low noise and low on-resistance

They are also available in surface mount 2SJ163/2SK1103
