Matched pair transistors

Matched pair transistors are double transistors with matched current gain hFE1/hFE2 and matched base-emitter voltage VBE1 - VBE2. The optimal product for the 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: hFE1/hFE2 = 0.7, 0.9, 0.95, 0.98

- Base-emitter voltage matching: VBE1 - VBE2 = 2 mV

- Standard double transistor pin-out for BCM-types

- Application optimized pin-out for all PMP-types

- Common emitter con guration for 5pin PMP-types

Key bene ts

- Improved performance of current mirror and differential ampli er circuits

- Drop-in replacement for standard double transistors (BCM-series)

- Simpli ed 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 ampli er e.g. sensor signal ampli cation

- Comparator e.g. for DC/DC converters
