USA3A

      USA3A is a kind of ultrafast avalanche diode.Here you can get some information about the features.First,the maximum solder temperature is 260.Secondly,the plastic material has UL classification 94V-0.Then is about the mechanical data.The plastic case is SMC/DO-214AB.The weight approx. is 0.21 g.The terminals are plated terminals solderable per MIL-STD-750.The mounting position is not limited.The standard packaging is 3000 pieces per reel.
      What comes next is about the absolute maximum ratings of USA3A (T_A=25).The I_FAV (maximum average forward current,R-load,T_T=100) is 3 A.The IFRM (repeatitive peak forward current,f>15 Hz) is 15 A.The I_FSM (peak forward surge current 50 Hz half sinus-wave) is 100 A.The I²t (rating for fusing,t<10 ms) is 50 A²s.The R_thA (maximum thermal resistance junction to ambient) is 50 K/W.The R_thT (maximum thermal resistance junction to terminals) is 10 K/W.The Tj (operating junction temperature) is from -50 to +150.The Ts (storage temperature) is from -50 to +150.
      The following is about the characteristics of USA3A (T_A=25).The I_R (maximum leakage current) is <3A.The E_RSM (non repeatitive peak reverse avalanche energy) is 20 mJ at I_R=1 mA,T_j=25,inductive load switched off.The V_RRM (repeatitive peak reverse voltage) is 50 V.The V_RSM (surge peak reverse voltage) is 50 V.The V_F (maximum forward voltage) is  1 V at T_j=25,I_F=2 A.The t_rr (maximum reverse recovery time) is 50 ns at I_F=0.5 A,I_R=1 A,I_RR=0.25 A.
