BA423

BA423 is a switching diode in hermetically sealed glass DO-34 envelope.It is intended for band switching in AM radio receivers.

What comes next is about the BA423 ratings (limiting values in accordance with the absolute maximum system (IEC 134)).The maximum V_R (continuous reverse voltage) is 20 V.The maximum I_F (forward current) is 50 mA.The T_stg (storage temperature) is from -65 to +150.The maximum T_j (junction temperature) is 150.The R_thj-a (thermal resistance from junction to ambient in free air mounted on a printed-circuit board at a lead-length of 10 mm) is 0.4 K/mW.

The following is about the BA423 characteristics (T_j=25).The V_F (forward voltage) is < 0.9 V at I_F=50 mA.The I_R (reverse current) is < 100 nA at V_R=20 V and is < 5 A at V_R=20 V,T_j=125.The C_d (diode capacitance) is < 2.5 pF at f=1 MHz,V_R=3 V.The r_s (series resistance) is <1.2 at I_F=10 mA,f=1 MHz.
