Philips Semiconductors Product specification VHF power transistor BLV20

DESCRIPTION

N-P-N silicon planar epitaxial transistor intended for use in class-A, transmitters with a nominal supply voltage of 28 V. The transistor is resistance stabilized and is guaranteed to withstand severe load mismatch conditions. It has a 3/8" flange envelope with a ceramic cap. All leads are isolated from the flange. PINNING - SOT123 PIN DESCRIPTION 1 collector 2 emitter 3 base 4 emitter QUICK REFERENCE DATA R.F. performance up to Th = 25°C in an unneutralized common-emitter class-B circuit PIN CONFIGURATION PRODUCT SAFETY This device incorporates beryllium oxide, the dust of which is toxic. The device is entirely safe provided that the BeO disc is not damaged.
