DMMT32N45CV-7R

Overview

The DMMT32N45CV-7R is a matched pair of NPN small-signal transistors housed in an SOT563 surface-mount package. It features a collector-emitter voltage (VCEO) of 45 V and a continuous collector current (IC) of 100 mA. The device provides a typical DC current gain (hFE) of 290 at IC = 2 mA, with a guaranteed matching ratio between the two dies of 0.95 to 1. Base-emitter voltage matching is maintained within a maximum differential of 2 mV. Electrical characteristics include a transition frequency (fT) of 300 MHz, low saturation voltages, and robust ESD protection rated at 4000 V via the Human Body Model.
