Microchip Technology SMAJ90E3/TR13 TVS Diode

The SMAJ90E3/TR13 from Microchip Technology is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system level events such as load dump, lightning, and electrostatic discharge (ESD). This TVS diode is a preferred choice for safeguarding vulnerable circuits in a wide range of applications including consumer electronics, automotive systems, and industrial equipment.

Encased in a compact SMA package, the SMAJ90E3/TR13 offers a discrete and space-saving solution for circuit protection. It is characterized by a standoff voltage of 90V, which makes it suitable for protecting systems operating at high voltage levels. Its peak pulse power dissipation is rated at 400W for a 10/1000μs waveform, ensuring that it can handle significant transient power spikes without compromising the integrity of the protected component.

The device features a fast response time, typically in the order of picoseconds, providing immediate protection against overvoltage events. This is critical for preserving the lifespan and functionality of sensitive components that can be damaged by rapid voltage increases. Moreover, the SMAJ90E3/TR13 is designed to maintain a low clamping voltage, which is the voltage level at which the device starts to conduct significant current to shunt excess energy away from the protected load. A lower clamping voltage translates to better protection for the end equipment.

Manufactured by Microchip Technology, a leader in microcontroller, mixed-signal, analog, and Flash-IP solutions, the SMAJ90E3/TR13 is a testament to the company's commitment to quality and reliability. The device is compliant with industry standards, including RoHS and REACH, ensuring environmental safety and global acceptance. It is provided in tape and reel packaging, designated by the "/TR13" suffix, which facilitates automated pick-and-place assembly processes for high-volume production environments.

With its combination of high surge capability, fast response time, and reliable performance under extreme conditions, the SMAJ90E3/TR13 TVS diode is an essential component for designers looking to enhance the durability and safety of their electronic systems.
