Matched pair transistors are double transistors with matched current gain

h

most common applications is offered by means of several matching-categories

and different pinning options. Internally the transistors are fully isolated.

Key features

- Current gain matching:

h

- Base-emitter voltage matching:

V

- Standard double transistor pin-out for

BCM-types

- Application optimized pin-out for all

PMP-types

- Common emitter configuration for

5pin PMP-types

Key benefits

- Improved performance of current mirror

and differential amplifier circuits

- Drop-in replacement for standard double

transistors (BCM-series)

- Simplified board layout (PMP-series)

- Eliminates need for costly

additional trimming

Key applications

- Current mirror e.g. for current

measurement or to drive LED’s with a

constant current

- Differential amplifier e.g. sensor

signal amplification

- Comparator e.g. for DC/DC converters
