Protection of electronic equipment has become an important consideration, and transient voltage suppressor (TVS) diodes have become an essential component in sustaining that protection. The growth in more sophisticated applications are placing greater demands on the TVS component, and the SMBJ16A-Q is one such product designed to meet the changes in design criteria. It delivers advanced features and desired performance to ensure reliable protection for sensitive electrical and electronic components.

SMBJ16A-Q is a TVS diode series available in a DO-214AA surface mount package, and is specifically designed to protect voltage sensitive components from high voltage transients. It is well suited for a broad range of industrial, military, and medical applications. It is suitable for use in both AC and DC systems, and is highly reliable yet provides excellent electrical performance. Its low capacitance and reverse leakage current ensure that it is highly suitable for use in circuit designs which involve the transmission of high frequency signals.

SMBJ16A-Q is a bidirectional transient voltage suppressor diode based on PN junction technology. It can handle transient voltages up to 16V, and has a low Clamping Voltage (Vc) of 8V. It also offers excellent peak pulse power dissipation with a maximum peak pulse power rating of 600 W. The maximum leakage current is very low – only 0.04 μA at a test voltage of 16V.

The SMBJ16A-Q provides reliable protection for a wide variety of applications. It is commonly found in automotive power systems, power supply circuits, medical equipment, and communication systems. It is rated for operation from -55 °C to 150 °C, and is RoHS (Restriction of Hazardous Substances) compliant, making it an environmentally-friendly choice for designs where hazardous substances are prohibited.

In terms of working principle, the SMBJ16A-Q adopts a Zener effect mechanism. When a transient voltage greater than 16V is applied to the device, the diode will automatically conduct current. This current provides an alternate path for the transient current to flow, thus eliminating the chance of damaging the components in the circuit. The current-limiting characteristics of the device further reduce the dissipated power, making it an effective solution for protecting sensitive electronics from transient voltages.

Overall, the SMBJ16A-Q provides a simple yet highly effective solution for protecting sensitive electronics from transient voltages. With its low capacitance and great peak pulse power performance, it is a versatile solution for a variety of applications. Its low leakage current contributes to its dependability, making it a reliable component for protecting electronic circuits. It is RoHS compliant, and is rated to both AC and DC operation, making it an excellent choice for designers looking for a reliable TVS diode solution.
