STMicroelectronics BZW04-376B Transil™ Diode

The BZW04-376B is a robust Transil™ diode from the reputable manufacturer, STMicroelectronics. This transient voltage suppressor (TVS) is engineered to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. It is a bidirectional device, meaning it can clamp both positive and negative voltage transients to a safe level.

With a stand-off voltage of 376V, the BZW04-376B ensures that devices remain safeguarded under specific voltage conditions, making it an ideal choice for a broad range of applications, including protection of I/O interfaces, VCC bus, and other vulnerable circuits. The device is capable of handling a peak pulse power dissipation of 1500W (10/1000µs), which is critical for high-energy transient protection.

The BZW04-376B comes in a DO-204AL package, also known as DO-15, which is a through-hole mounting design. This package type is widely used and recognized for its reliability and ease of soldering onto printed circuit boards. The diode's junction passivation optimized design and axial leads provide enhanced mechanical strength and thermal resistance, ensuring stable performance across a wide temperature range of -55°C to +175°C.

STMicroelectronics has designed the BZW04-376B with a fast response time, typically in the picosecond range, providing immediate protection against transient overvoltages. Additionally, its low clamping factor and high surge capability make it an efficient solution for protecting sensitive components.

The device is compliant with the IEC 61000-4-2 and IEC 61000-4-4 standards, which are important for electromagnetic compatibility (EMC). It is also RoHS compliant, ensuring that it meets the latest environmental regulations and restrictions on hazardous substances.

In summary, the STMicroelectronics BZW04-376B Transil™ diode is a high-performance solution for transient voltage suppression. Its robust design, high power dissipation, and compliance with industry standards make it a reliable and essential component for circuit protection in a wide array of electronic systems.
