BZW50-12B – NJS

The BZW50-12B, manufactured by NJS, is a 50W transient voltage suppressor (TVS) diode packaged in an R-6 axial leaded configuration. This device is designed for transient overvoltage protection, specifically clamping voltages resulting from electrostatic discharge (ESD), inductive load switching, and other transient voltage events. The diode features a working peak reverse voltage (VWM) of 12V, indicating the maximum DC voltage that can be applied without significant leakage current. Its breakdown voltage is typically slightly above 12V. The clamping voltage (VC), specified at 28V, represents the maximum voltage the diode will allow to pass when subjected to a peak pulse current. The R-6 package provides adequate power dissipation for its 50W surge capability, making it suitable for protecting sensitive electronic components in various applications.
