DFLT48A-7

TVS – Diodes (Transient Voltage Suppressors) are devices that are designed to protect against voltage spikes or electrical surges that might otherwise damage other components. The DFLT48A-7 is a unidirectional TVS diode that can be used in a range of applications. In this article, we will look at the application field and working principle of the DFLT48A-7.

The DFLT48A-7 is primarily used in automotive, consumer, industrial, and telecom applications. This is due to its low power dissipation, high standoff voltage, and wide operating temperature range. In automotive applications, the DFLT 48A-7 can be used to protect circuitry from ESD (electrostatic discharge) as well as any other transients that may be present. Additionally, the device is well suited for power supplies, providing additional protection for sensitive components. In consumer applications, the DFLT 48A-7 is often used to protect logic ICs and fuses from overvoltage, and in industrial applications it is used to protect DC/DC converters, ACS switches, programmable controllers, and motor control modules from destructive voltage transients.

In terms of its working principle, the DFLT48A-7 is designed to absorb energy and clamp the voltage whenever an overvoltage spike occurs. This is achieved using the device’s PN-junction, which reacts to the amount of voltage present. When the power supply voltage exceeds the device’s peak surge power, the PN-junction switches into its conduction region, thereby reducing the voltage spike and protecting any connected components. The DFLT48A-7 can sustain a peak power of 48A and a working peak voltage of 8.5V, making it an effective protection device for systems that may be exposed to short-duration high-voltage spikes.

In summary, the DFLT48A-7 is a unidirectional TVS diode that is well-suited for a range of applications, including automotive, consumer, industrial, and telecom. Its low power dissipation, high standoff voltage, and wide operating temperature range make it ideal for these uses. Furthermore, its PN-junction is designed to turn on and clamp the voltage whenever a surge is detected, providing protection for connected components. Overall, the DFLT48A-7 is an effective solution for protecting circuits from voltage spikes.
