The BZW50-33B is a high-performance transient voltage suppression (TVS) diode, part of STMicroelectronics' Transil range. This robust diode is specifically designed to protect sensitive electronic equipment against voltage transients induced by system inductive load switching and lightning. With its bidirectional clamping feature, it is an ideal solution for absorbing high transient overvoltages while maintaining a low clamping voltage to ensure the protection of the device it's safeguarding.

Key Features

• Peak Pulse Power: The BZW50-33B offers an impressive peak pulse power dissipation of 5000W (10/1000μs surge), making it capable of handling significant surge events.
• Stand-off Voltage: It has a stand-off voltage of 33V, which helps prevent the diode from conducting in normal operation, thus reducing power consumption.
• Breakdown Voltage: The breakdown voltage range is from 36.7V to 44.2V, which ensures the device activates only when the voltage exceeds the normal operating level.
• Low Clamping Voltage: Upon activation, the BZW50-33B clamps the overvoltage to a minimal level, protecting sensitive components from electrical stress.
• Fast Response Time: The diode's response time is virtually instantaneous (
• High Reliability: Thanks to its glass passivated chip junction, the BZW50-33B is highly reliable and stable over its lifespan.
• Package: Available in a molded package, it is designed for easy PCB mounting and is suitable for high-density installations.

Applications

The BZW50-33B is suitable for a wide range of applications where transient voltage protection is critical. These include:

• Power supply devices
• Telecommunication systems
• Industrial equipment
• Lightning protection
• Surge protection devices

With its combination of high surge capability, fast response, and low clamping voltage, the BZW50-33B from STMicroelectronics is an excellent choice for designers looking to enhance the durability and reliability of their electronic systems.
