Chip capacitors are passive components utilized by engineers and designers to store electrical energy to some extent, dissipate power surges, filter high frequency signals, or develop a timing delay between two signal lines. SMAJ22C-E3/61 is a special type of chip capacitor in the TVS-Diodes product family. It is a bi-directional transient voltage suppressor diode designed with silicon avalanche technology. Knowing how it works and where it can be used are essential components in investing in the right chip capacitor.

Applications of SMAJ22C-E3/61

SMAJ22C-E3/61 is used mostly on circuit elements where transient voltage overshoot protection is required from high voltage transients or electronic surges. Highly beneficial in the protection of high-speed data cables, control signals, and power supply circuits, SMAJ22C-E3/61 offers excellent clamping capability and low leakage current. It is widely utilized in telecommunication equipment, digital cameras, computer peripheral products, power lines, and automotive electronic systems, among others.

Working Principle of SMAJ22C-E3/61

Transient voltages are generated in many circumstances like switching, lightning surges, and ESD. Charged with a special polarity of electrons in the PN junction region, silicon avalanche voltage in the reverse direction determines the flow of current at low breakdown strength and limits the reverse energy created from the surge. When applied reverse voltage becomes higher than the breakdown voltage value, avalanche breakdown occurs, and the diode starts conducting.

As the avalanche breakdown in SMAJ22C-E3/61 is highly temperature dependent and very fast in comparison to other types of devices, it is highly beneficial in providing voltage clamping protection against severe surges. Its internal temperature limit helps to avoid catastrophic events during any high current tvs surge.

Conclusion

SMAJ22C-E3/61 is an excellent component for protecting circuit elements from transient voltage overshoot. It is specifically designed for coaxial cable systems, signal lines, impulse protection, and more. Being an avalanche diode, it is temperature-independent and highly efficient in providing a low clamping voltage with a low leakage current in comparison to other diode technologies. Its high surge handling capability and fast response are especially beneficial in ensuring voltage transient protection.
