ON Semiconductor P6SMB18AT3 Transient Voltage Suppressor

The ON Semiconductor P6SMB18AT3 is a robust transient voltage suppressor (TVS) designed to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events. This high-performance device is part of ON Semiconductor's P6SMB series, which is known for its reliability and efficiency in safeguarding circuits by clamping excessive transient voltages to a safe level before they can damage sensitive components.

Constructed with a surface-mount SMB (DO-214AA) package, the P6SMB18AT3 is suitable for automated assembly processes and occupies minimal board space, making it an excellent choice for compact electronic designs. The TVS diode offers a standoff voltage of 18V, which is the maximum voltage that can be applied continuously to the device without causing it to conduct significant current. This feature ensures that the device remains inactive during normal operation and only responds when the voltage exceeds its designed threshold.

Featuring a 600W peak pulse power capability with a 10/1000μs waveform, the P6SMB18AT3 is capable of handling substantial power surges, ensuring reliable protection against high energy transients. The response time of the device is less than 1 picosecond from 0V to BV min, providing immediate protection when a transient voltage occurs.

The P6SMB18AT3 is also characterized by its excellent clamping capability, low incremental surge resistance, and fast response time, which make it an ideal choice for protecting voltage-sensitive components such as ICs, MOSFETs, and signal lines from electrical threats. Moreover, it meets the ISO 7637-2 surge specification and is compliant with the RoHS directive, which restricts the use of certain hazardous substances in electronic equipment.

With its robust construction and reliable performance, the ON Semiconductor P6SMB18AT3 is a suitable protective component for a wide range of applications, including automotive systems, industrial equipment, power supplies, and communication devices. Its ability to safeguard against transient overvoltages makes it an essential component for any design that requires high levels of circuit protection.
