Philips Semiconductors Product specification HF/VHF power transistor BLW77
DESCRIPTION
N-P-N silicon planar epitaxial transistor intended for use in class-AB or class-B operated high power bands. The transistor presents excellent performance as a linear amplifier in the h.f. band. It is resistance stabilized and is guaranteed to withstand severe load mismatch conditions. Transistors are delivered in matched h FE groups. The transistor has a1⁄2" flange envelope with a ceramic cap. All leads are isolated from the flange. QUICK REFERENCE DATA R.F. performance up to T h = 25°C Note 1. At 130 W P.E.P.
