Product Description

STMicroelectronics BZW50-18 is a high-performance uni-directional Transil™ TVS diode designed for transient voltage suppression applications in electronic and power circuit protection. It features a single element diode configuration within a compact 2-pin R-6 package suitable for through hole mounting.

This diode supports a peak pulse power dissipation of 5000 W, making it ideal for protecting circuits against voltage spikes and transient surges. Its minimum breakdown voltage is 20 V, with a maximum reverse stand-off voltage of 18 V, ensuring stable suppression without causing damage under normal operating conditions.

The device clamps voltage at 41.5 V during transient events, with a peak pulse current capability of 1446 A at a test current of 1 mA. Operating temperature ranges from -65°C to 175°C enabling reliable performance in harsh industrial, automotive, and electronic environments. It complies with UL standards, assuring quality and safety.

The physical dimensions include a 9.1 mm diameter and length, fitting standard PCB assemblies requiring axial through hole components. The maximum reverse leakage current is 5 μA, helping maintain low power loss in normal operation.

Applications include industrial control systems, power supplies, communication devices, and automotive electronics where protection against electrostatic discharge and voltage transients is critical.

Designed for transient voltage suppression to safeguard electronics. Single element, uni-directional configuration for reliable clamping. 5000 W peak pulse power ensures high surge handling capability. Wide operating temperature from -65°C to 175°C for industrial usage.

Compact axial through hole R-6 package supports easy PCB mounting. Low leakage current enhances efficiency and reduces power waste. UL recognized component meets strict safety and quality standards. High peak pulse current rating suitable for demanding environments.
