5. Recommend DrivingCircuit
The base current Ib should high enough so that it saturates the collectorcurrent of the transistor
with the CB load.
6. Soldering Condition
(1) Recommendablereflow soldering condition is as follows
(Reflow solderingis twice)
Note:It is requested that reflow soldering should be executed
after heat of product goes down to normal.
Heat resistant line
(Used when heat resistantreliability test is performed)
(2)Manualsoldering
Manual soldering temperature 350 ºC within 5 sec.
