ASY48

ASY48 is alloyed germanium PNP transistor in 1 A 3 DIN 41871 case (similar to TO 1).The leads are electrically insulated from the case.The collector terminal is marked by a red dot at the edge of the case.The transistor is particularity suitable for switching applications.

What comes next is about the maximum ratings of ASY48.The -V_CEO (collector-emitter voltage) is 45 V.The -V_CEV (collector-emitter voltage) is 64 V when V_BE0.2 V.The -V_CBO (collector-base voltage) is 64 V.The -V_EBO (emitter base voltage) is 16 V.The -I_C (collector current) is 300 mA.The -I_B (base current) is 60 mA.The T_j (junction temperature) is 90.The T_stg (storage temperature range) is from -55 to +75.The P_tot (total power dissipation (T_case=45)) is 900 mW.Then is about the thermal resistance.The R_thJA (junction to ambient air) is 300 K/W.The R_thJC (junction to case) is 50 K/W.

The following is about the static characteristics of ASY48 (T_amb=25).The -I_CBO (collector cutoff current) is <10 A at -V_CBO=10 V and is 6 (<18) A at -V_CBO=64 V.The -I_EBO (emitter cutoff current) is 4 (<18) A at -V_EBO=16 V.The -I_CEV (collector cutoff current) is 6 (<18) A at -V_CEV=64 V,V_BE0.2 V. The -V_CEsat (collector-emitter saturation voltage) is 0.15 (<0.25) V.
