Product specification

NPN general purpose transistors

BCY87; BCY88; BCY89

FEATURES

• Low current (max. 30 mA)

• Low voltage (max. 45 V).

APPLICATIONS

• Differential amplifier applications in general industrial

service e.g. instrumentation and control

• The BCY87 and BCY88 are intended for use in

pre-stages of differential amplifiers where low offset, low

drift and low noise are of prime importance

• The BCY89 is intended for use in second stages of

differential amplifiers, long-tailed pairs and more general

applications.

DESCRIPTION

Matched dual NPN transistors in a TO-71; SOT31 metal

package. Products are divided into 3 types according to

their matching accuracy.

PINNING

Note
