2N3498U4/TR

Single Bipolar Transistors Overview

The Microchip Technology 2N3498U4/TR is a silicon NPN single bipolar junction transistor (BJT) designed for through-hole mounting in TO-39-3 packages. It supports a maximum DC collector current of 500 mA and withstands collector-emitter voltages up to 100 V, with a collector-base voltage rating of 100 V and an emitter-base voltage limit of 6 V. The device dissipates 1 W of power and operates within a temperature range of -65°C to +200°C. Its DC current gain ranges from a minimum of 15 at 500 mA to a maximum of 120 at 150 mA, both measured at 10 V. Collector-emitter saturation voltage is specified at 600 mV.
