series introduction
The 1SMB28 Series is a premier line of surface-mount transient voltage suppressors (TVS) designed to protect sensitive electronic components from voltage spikes and surges. Characterized by their robust construction and outstanding clamping performance, these devices are an essential choice for engineers seeking reliable over-voltage protection in a compact form factor. The 1SMB28 Series features a unidirectional configuration, accommodating reverse polarity applications while ensuring low leakage current, typically less than 5 µA. This makes them ideal for safeguarding circuits in both AC and DC applications.
These transient voltage suppressors are constructed using high-quality semiconductor materials that allow for rapid response times and excellent power dissipation capabilities. With a breakdown voltage of 28V, the 1SMB28 Series effectively mitigates the risk of damaging voltage spikes, providing a clamping voltage that is consistently below the maximum ratings of downstream components. The series is designed to handle peak pulse power ratings of up to 600W, making it suitable for a wide array of demanding environments and applications.
The compact package design of the 1SMB28 Series, adhering to the SMB footprint, allows for easy integration into various circuit layouts, making it particularly advantageous in space-constrained applications. These TVS diodes are well-suited for use in consumer electronics, telecommunications, automotive electronics, and industrial automation systems. They are commonly deployed for protecting communication lines, power supplies, and sensitive circuitry in devices such as smartphones, laptops, and automotive control modules.
In summary, the 1SMB28 Series combines high-performance surge protection with a versatile design, making it an excellent choice for engineers looking to safeguard their electronic designs against transient voltage events. With its reliable performance and extensive application range, the 1SMB28 Series stands out as a critical component for enhancing the longevity and durability of electronic systems.
