BZX384-B39,115 Description

Short technical summary and product information.

The BZX384-B39,115 is a low-power voltage regulator diode from the Nexperia BZX384 series. It provides a nominal zener voltage of 39V with a ±2% tolerance (BZX384-B grade). This diode is designed for general regulation functions and offers a maximum power dissipation of 300mW at ambient temperatures up to 25°C when mounted on a standard FR4 PCB. Key electrical characteristics include a maximum forward voltage of 0.9V at 10mA and 1.1V at 100mA, with a maximum reverse leakage current of 50nA at 27.3V. The zener impedance is 130Ω maximum. The device is housed in an SOD323 (SC-76) plastic surface-mount package, ideal for compact designs. It operates over a temperature range of -65°C to 150°C. The BZX384 series includes 37 breakdown voltages from 2.4V to 75V, with this specific variant being the 39V ±2% option. Applications include voltage regulation in low-power circuits.
