A TVS - Diodes device is an electrical component designed to protect sensitive circuits, such as those found in automotive, industrial, and audio applications, from electrical transients. The SMDJ45CA is a type of transient voltage suppression (TVS) diode designed specifically to protect sensitive components from high-energy, transient voltage events up to 45V.
TVS - Diodes offer surge protection, as they act immediately (typically within nanoseconds) to clamp and absorb any transient voltages that are higher than the TVS’s rating, thus protecting delicate or vulnerable circuits from damage. The SMDJ45CA can be used in a wide range of applications, including computers, data lines, telecommunication equipment, test and measurement equipment, LEDs, and other sensitive electronic circuits.
Working Principle
The SMDJ45CA works in much the same way as other traditional TVS diode devices, through a process known as "clamping". When a transient voltage event is detected, the SMDJ45CA activates to reduce the voltage by clamping the applied voltage between two levels – the breakdown voltage and the clamping voltage. Once the voltage has been clamped, the dielectric and breakdown capacitance within the SMDJ45CA provide additional protection against the transient surge.
The SMDJ45CA has a voltage rating of 45V and is capable of withstanding continuous operating voltages of up to 35V. This makes it ideal for use in applications where the input voltage might frequently exceed the rated value without permanent damage to the device. The SMDJ45CA can handle up to 10A of DC current, and up to 8A of peak pulse current.
The SMDJ45CA has a reverse stand-off voltage of 37.5V and a reverse break-down voltage of 55V. In order to protect the diodes from damage, the reverse break-down voltage must be below 50V. This ensures that the device can withstand transient surges without suffering any catastrophic failure.
Package and mounting
The SMDJ45CA is available in two lead-free packages, in both standard and surge versions. The standard package is available in 0805 and 1206 sizes, whilst the surge version is available in both 0201 and 0402 sizes. The 0201 and 0402 sizes are particularly suitable for use in applications requiring small size and high density mounting.
The device is also compatible with reflow solder mounting techniques, making it suitable for high-volume manufacturing processes. The standard package is also UL-recognized for top side mounting, whilst the surge package is recognized for reflow or bottom side mounting.
Applications
The SMDJ45CA can be used in a wide variety of applications, including automotive, industrial, and audio applications. It is also suitable for use in computers, data lines, telecommunication equipment, test and measurement equipment, and lighting systems.
In automotive applications, the SMDJ45CA is well suited for providing protection against voltage spikes due to ignition systems, alternators, starters, and electro-magnetic interference. In industrial applications, the SMDJ45CA can be used to protect against transients caused by lightning and switching noise.
In audio applications, the SMDJ45CA is capable of providing protection against transients which can be caused by speakers, headsets, and sound cards. The device is also well suited for protection against EMI generated by microwaves, radio waves, and cellular phones.
Conclusion
The SMDJ45CA is a reliable and robust transient voltage suppression (TVS) diode designed for use in a wide range of applications. It can provide protection against electrical transients up to 45V, and can handle up to 10A of DC current, and up to 8A of peak pulse current.
The device is available in two lead-free packages, in both standard and surge versions, and is compatible with reflow solder mounting techniques for high-volume manufacturing. The SMDJ45CA is suitable for use in automotive, industrial, and audio applications, as well as computers, data lines, telecommunication equipment, test and measurement equipment, and LED lighting systems.
