DISCRETE SEMICONDUCTORS DATA SHEET BF510 to 513 N-channel silicon field-effect transistors December 1997 Product specification File under Discrete Semiconductors, SC07 Philips Semiconductors Product specification N-channel silicon field-effect transistors BF510 to 513 DESCRIPTION MARKING CODE Asymmetrical N-channel planar BF510 = S6p epitaxial junction field-effect BF511 = S7p transistors in the miniature plastic BF512 = S8p envelope intended for applications up BF513 = S9p to the v.h.f. range in hybrid thick and thin-film circuits. Special features are the low feedback capacitance and the low noise figure. These features make the product very suitable for applications such as the r.f. stages in f.m. portables (BF510), car radios 3 handbook, halfpage (BF511) an
