STMicroelectronics 1-Element Bi-Directional TVS Diode 5 kW, 2-Pin R-6 BZW50-39B

STMicroelectronics BZW50-39B is a robust 1-element bi-directional TVS diode designed to provide transient voltage suppression at a peak pulse power dissipation of 5 kW. Packaged in a through-hole R-6 axial form factor, it features a single diode configuration optimized for protection against high-energy voltage spikes and surges.

The diode supports both AC and DC applications with its bi-directional capability, delivering reliable performance by clamping transient voltages at 90 volts while sustaining a minimum breakdown voltage of 43.3 volts and a maximum reverse stand-off voltage of 39 volts. This makes it well-suited for safeguarding sensitive electronic components in industrial, automotive, and consumer electronics environments where voltage surges can cause damage.

The compact 9.1 mm diameter and length dimensions facilitate easy integration on printed circuit boards with standard through-hole mounting. It can withstand maximum peak pulse currents up to 667 amperes, ensuring protection against significant surge events. Moreover, its low maximum reverse leakage current of 5 microamperes minimizes power dissipation during normal operation, improving overall system efficiency.

Designed to operate at temperatures up to 175°C, the BZW50-39B diode is suitable for harsh environments requiring stable electrical performance. Its package type R-6 and axial leaded design simplify assembly and replacement in various electronic circuits.

This transient voltage suppressor diode is an essential component for power electronics protection in industrial automation, telecommunications, and power supply applications. It helps enhance system reliability by preventing damage induced by sudden transient voltage spikes.
