ULN2065B Description

Short technical summary and product information.

The STMicroelectronics ULN2065B is a quad NPN Darlington transistor array. It is rated for up to 80V and can handle a continuous current of 1.75A per channel. The device operates within a temperature range of -20°C to 85°C.

 

This transistor array is housed in a 16-pin PowerDIP package, suitable for through-hole mounting. Its Vce saturation is a maximum of 1.5V at 2.25mA base current and 1.5A collector current. The component has a power dissipation rating of 1W.

 

Key electrical characteristics include its 80V breakdown voltage and 1.75A current handling capability. The 4 NPN Darlington configuration makes it suitable for driving loads such as relays, solenoids, and lamps where higher current gain is required.
