PDTC144ET/DG/B2,21

Overview

The PDTC144ET/DG/B2,21 is an NPN Resistor-Equipped Transistor (RET) from the PDTC144E series, housed in a SOT23 plastic surface-mounted package. It integrates bias resistors with R1 = 47 kΩ and R2 = 47 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, output current capability of 100 mA, and DC current gain (hFE) minimum of 80 at IC = 5 mA. The device operates within a junction temperature range of -65 °C to +150 °C and features a total power dissipation of 250 mW.
