DESCRIPTION
Matched dual NPN transistors in a TO-71; SOT31 metal package. Products are divided into 3 types according to their matching accuracy.

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.
