Overview
The PDTC143ZU/ZLX is a 50 V, 100 mA NPN resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. This transistor is packaged in a small SOT323 (SC-70) surface-mounted device (SMD) plastic package, making it ideal for space-constrained designs. The built-in bias resistors simplify circuit design and reduce the overall component count, thereby lowering pick and place costs. This transistor is a cost-saving alternative to the BC847 series in digital applications and is widely used in controlling IC inputs and switching loads.
