I've been through three online transistor cross references without
luck. I am looking for a small NPN that would cross to this:
Original transistor: BC407B
Material of Transistor: Si
Polarity: NPN
Maximum Collector Power Dissipation (Pc): 0.25 W
Maximum Collector-Base Voltage |Vcb|: 50 V
Maximum Collector-Emitter Voltage |Vce|: 45 V
Maximum Emitter-Base Voltage |Veb|: 6 V
Maximum Collector Current |Ic max|: 0.1 A
Max. Operating Junction Temperature (Tj): 125 °C
Transition Frequency (ft): 150 MHz
Collector Capacitance (Cc): 5 pF
Forward Current Transfer Ratio (hFE), MIN: 200
This transistor is used in the audio amplifier board of a Ten-Tec
Argonaut 505. I have several small NPN's on hand but nothing that
quite matches a BC407B.
Thanks,
