Bipolar transistors

Eliminate the need for costly trimming

Our new matched pair transistors ensure accurate base-emitter voltage (VBE1 / VBE2) and current gain (hFE1 / hFE2) matching and are fully internally isolated. As a replacement for standard double transistors in current mirror and differential amplifier applications, they eliminate the need for further costly trimming.
