BZT52C39-7-F Surface Mount Voltage Limiting Diode

BZT52C39-7-F is a 39 V Zener diode for regulation, voltage limiting, and protection networks. It combines a 500 mW power rating with an SOD123 surface-mount package. The higher nominal breakdown voltage suits circuit nodes that operate above common logic and low-voltage control rails. Use the part with correctly sized series impedance so Zener current remains within the intended operating region. Confirm dissipation during steady-state regulation as well as short-duration overvoltage events. The device can support shunt-reference stages, bias networks, and input clamps when its electrical limits match the design. During component selection, allow for voltage tolerance and temperature effects during worst-case analysis across expected supply and load conditions. Request a quote for BZT52C39-7-F.
