Description

The BFW11 is a silicon N-channel junction field-effect transistor (JFET) listed in the Agenda radioelectronistului (2nd edition, 1989) among the field-effect transistors made in Romania by ICCE (marked in the Agenda as a CCSIT-CE component), in a TO-72 package [1].

Coded as (Pro Electron system) [2]:

Part Meaning
B base material with an activation energy of 1.0–1.3 eV, e.g. silicon (1.1 eV)
F high-frequency, low-power transistor
W11 serial number for components for professional use: a letter (X, Y, Z…, with no coded meaning) and two digits (10–99)
