ON Semiconductor SA28AG Product Overview

The ON Semiconductor SA28AG is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events. This high-performance device is a crucial component for industries where reliability and durability are paramount, such as in automotive, industrial, and telecommunication applications.

The SA28AG is characterized by its 28V standoff voltage, which is the voltage below which the device remains non-conductive and provides high impedance. It is capable of handling significant energy spikes with its 500W peak pulse power capability for a 10/1000μs waveform. This feature ensures that devices are shielded from sudden surges of power, which could otherwise cause irreparable damage.

ON Semiconductor has designed the SA28AG with a unidirectional configuration, meaning it provides protection in a single direction, making it ideal for DC power line applications. Its fast response time is critical for ensuring that protection is activated almost instantaneously upon detection of a voltage surge.

The SA28AG comes in a molded JEDEC DO-15 package, known for its compact size and reliability. The package is also lead-free and RoHS compliant, adhering to current environmental standards that aim to reduce hazardous substances in electronic components. This commitment to environmental sustainability does not compromise the device's performance or durability.

Key features of the SA28AG include its low incremental surge resistance and excellent clamping capability, which ensure that the device can effectively clamp transient voltages to a safe level, preventing damage to the protected component. It is also rated for operation over a wide temperature range, making it suitable for harsh environmental conditions.

In summary, the ON Semiconductor SA28AG is a high-quality, reliable solution for transient voltage suppression. Its ability to withstand significant power surges, combined with its fast response time and environmental compliance, make it an excellent choice for protecting sensitive electronic circuits in a variety of demanding applications.
