Microchip Technology's SMBJ28CE3/TR13 Transient Voltage Suppressor Diode

The SMBJ28CE3/TR13 from Microchip Technology is a high-quality transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage spikes and surges. This robust component is part of Microchip's extensive range of circuit protection devices, offering reliable performance in a compact SMB (Surface-Mounted Device) package. It is specifically tailored for applications that require a 28V stand-off voltage, making it suitable for a variety of industrial, computing, and consumer electronics applications.

This TVS diode is capable of handling high transient power with its peak pulse power dissipation of 600W for a 10/1000μs waveform. This ensures that devices are shielded from sudden and momentary overvoltage events, such as those caused by lightning strikes, electrostatic discharge (ESD), or switching transients in the power supply. The SMBJ28CE3/TR13 is designed to respond rapidly, clamping the excess voltage and diverting the surge current away from the protected component, thereby preventing potential damage.

Featuring a unidirectional configuration, the SMBJ28CE3/TR13 offers precise clamping characteristics. Its low incremental surge resistance helps in maintaining a low clamping voltage during surge events, which is critical for the protection of sensitive circuitry. The device is compliant with the IEC 61000-4-2 standard for ESD immunity, ensuring that it can withstand ESD strikes without degradation of its performance.

The SMBJ28CE3/TR13 is provided in a tape and reel format with the designation TR13, indicating that it is ready for automated pick-and-place assembly processes, which is ideal for high-volume production environments. The device also meets the RoHS and REACH standards, ensuring that it is free from hazardous substances and compliant with environmental regulations.

Overall, the SMBJ28CE3/TR13 TVS diode from Microchip Technology is a reliable and efficient solution for protecting sensitive electronics from voltage transients. Its quick response time, high surge capability, and compliance with industry standards make it an excellent choice for designers looking to enhance the durability and reliability of their electronic systems.
