The BA12001B, BA12003B, BA12003BF, and BA12004B are high voltage, high current, high sustain voltage transistor
arrays consisting of seven circuits of Darlington transistors.
Because it incorporates built-in surge-absorbing diodes and base current-control resistors needed when using inductive
loads such as relay coils, attachments can be kept to a minimum.
With an output sustain voltage as high as 60V and an output current (sink current) of 500mA, this product is ideal for use
with various drivers and as an interface with other elements.
zApplications
Drivers for LEDs, lamps, relays and solenoids

3) Seven Darlington transistors built in.
4) Built-in surge-absorbing clamp diode.
(Note : Refer to the “Reference items when using in application.” )
