Overview
The PBSS4021NT/WD215 is a 20 V, 4.3 A NPN low VCEsat (BISS) transistor manufactured by Nexperia, previously part of NXP USA Inc. This transistor is designed for high-performance applications requiring low collector-emitter saturation voltage and high collector current capability. It is packaged in a compact SOT23 surface-mounted device (SMD) plastic package, making it ideal for space-constrained designs.
