BLW81 is UHF power transistor manufactured by NXP Semiconductors.
DISCRETE SEMICONDUCTORS DATA SHEET BLW81 UHF power transistor Product specification March 1993 Philips Semiconductors UHF power transistor DESCRIPTION N-P-N silicon planar epitaxial transistor intended for transmitting applications in class-A, B or C in the u.h.f. and v.h.f. range for a nominal supply voltages up to 13,5 V. The resistance stabilization of the transistor provides protection against device damage at severe load mismatch conditions. The transistor is housed in a 1⁄4" capstan envelope with a ceramic cap.
