STMicroelectronics 1-Element Bi-Directional TVS Diode 5 kW 2-Pin R-6 BZW50-120B

STMicroelectronics BZW50-120B 1-Element Bi-Directional TVS Diode provides high reliability transient voltage suppression with 5 kW peak pulse power dissipation and a 2-pin R-6 through-hole package.

This single-element bi-directional diode configuration is optimized for protecting sensitive electronic components from voltage spikes and transient surges commonly encountered in industrial, electronic, and power supply applications.

The diode has a minimum breakdown voltage of 133 volts with a maximum standby reverse voltage of 120 volts ensuring robust operation under normal conditions. Its clamping voltage peaks at 274 volts, effectively limiting transient overvoltage to safe levels while the maximum peak pulse current rating of 219 amps allows handling of high surge currents.

With an operating temperature range from -65°C to +175°C, this diode is suitable for use in extreme environmental conditions, maintaining consistent surge protection performance. The compact axial R-6 package measures 9.1 mm in diameter, length, width, and height, making it convenient for space-constrained PCB designs with through-hole mounting.

The maximum reverse leakage current is very low at 5 microamperes, minimizing standby power consumption and ensuring efficiency.

This TVS Diode is an ideal choice for transient suppression in industrial electronics, power supplies, automotive systems (though not automotive certified), and other applications requiring robust voltage spike protection.

This diode is indispensable for safeguarding circuits from damaging voltage transients in industrial and electronic equipment. Its compact size and through-hole mounting enable easy integration into existing PCB designs.
