If you need power transistors, you can use some of these:

 MOSFET  Channel P:

• IRF9540    Vds=-100V, RdsON=0.20 Ohm at Vgs=-10V

Third generation Power MOSFETs from Vishay provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness. The TO-220AB package is universally preferred for all commercial-industrial applications at power dissipation levels to approximately 50 W. The low thermal resistance and low package cost of the TO-220AB contribute to its
wide acceptance throughout the industry.

 Bipolar NPN:

• 2SC1815   Vceo=50V, Ice=150 mA, hfe=100 (typ.)
