BZW50-68

BZW50-68 Description

The BZW50-68 from STMicroelectronics' BZW50, TRANSIL™ series is a high-performance unidirectional Zener-type TVS diode designed for general-purpose transient voltage suppression. With a 68V reverse standoff voltage (Typ) and a minimum breakdown voltage of 75.6V, it provides robust protection against voltage spikes. The diode features an exceptionally high peak pulse current capability of 382A (8/20µs) and a clamping voltage of 157V at peak pulse current (Ipp), ensuring reliable safeguarding for sensitive electronics. Its low capacitance of 3000pF @ 1MHz minimizes signal distortion, making it suitable for high-speed circuits.

BZW50-68 Features

• High Power Handling: 5000W (5kW) peak pulse power dissipation for superior surge protection.
• Low Clamping Ratio: Tight voltage clamping (157V max) limits overvoltage stress on downstream components.
• Fast Response Time: Rapid reaction to transient events, ensuring minimal exposure to damaging spikes.
• RoHS3 & REACH Compliant: Environmentally friendly and meets global regulatory standards.
• Through-Hole Mounting: Easy integration into PCB designs for robust mechanical and electrical connections.
• Unidirectional Protection: Optimized for DC circuits, providing effective suppression of positive transients.

BZW50-68 Applications

• Industrial Electronics: Protects control systems, PLCs, and motor drives from voltage surges.
