STMicroelectronics BZW50-39 Transil™ Bidirectional Transient Voltage Suppressor

The BZW50-39 from STMicroelectronics is a high-quality Transil™ transient voltage suppressor (TVS) designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. This robust component is an essential part of any circuit where reliable protection against voltage spikes is crucial.

With its bidirectional clamping feature, the BZW50-39 is capable of protecting circuits on both positive and negative transients, making it a versatile solution for a wide range of applications. This TVS device is particularly well-suited for protecting voltage-sensitive components which can be found in telecom systems, computer interfaces, and other industrial and consumer electronics.

Constructed with high-surge capability, the BZW50-39 can handle pulses from 10/1000μs up to 50A, ensuring that devices remain safe even under extreme conditions. Its standoff voltage is 39V, which is the maximum voltage that can be applied while maintaining the device in its non-conductive state, providing a substantial margin against electrical surges.

The BZW50-39 comes in a rugged axial-lead package and is designed to meet the rigorous standards of IEC 61000-4-5 and ISO 7637-2, which are the international standards for lightning and surge protection. This certification underscores its reliability and effectiveness in safeguarding electronic components.

Key features of the BZW50-39 include:

• Peak pulse power: 1500W (10/1000μs)
• Standoff voltage: 39V
• Breakdown voltage range: From 43.5V to 48.1V
• Maximum clamping voltage: 64.8V at 23.3A
• Low incremental surge resistance
• High-temperature soldering guaranteed: 260°C/10s/0.375” (9.5mm) lead length at 5 lbs (2.3kg) tension

With its high surge capability and robust construction, the BZW50-39 is an excellent choice for ensuring the longevity and reliability of electronic systems. Whether used in power supply units, consumer electronics, or industrial applications, this TVS diode from STMicroelectronics provides critical protection against transient overvoltage, securing the integrity of your electronic equipment.
