ZN4401 – TBC

The ZN4401 is a discrete NPN bipolar junction transistor (BJT) requiring a Certificate of Conformance (C of C) from the National Semiconductor Corporation (N.S.C.). This specification implies a device intended for high-reliability applications or those subject to stringent quality control. Given the NPN configuration, the ZN4401 likely features a silicon die with a base-emitter forward voltage (Vbe) typically around 0.7V. Without further specifications, key electrical characteristics such as collector-emitter breakdown voltage (Vceo), collector current (Ic), power dissipation (Pd), and current gain (hFE) remain undefined. The C of C requirement suggests traceability and adherence to specific manufacturing processes and testing protocols established by N.S.C. at the time of production, indicating a focus on consistent performance and long-term reliability within its intended application. Further datasheet information is necessary to determine precise operating parameters.
