TVS – Diodes

The ESDALC7-1BF4 is a TVS (Transient Voltage Suppression) diode designed to protect sensitive electronic circuits from voltage transients. These transients can be caused either by electrical noise from the environment or simply by electrical overstress (EOS) or electrostatic discharge (ESD) when the device is handled improperly. The ESDALC7-1BF4 is mainly used in automotive, telecoms, consumer and data communication applications.

Application Fields

The ESDALC7-1BF4 can be used in a variety of different applications across the automotive, telecom, consumer and data communication markets. Automotive: This TVS diode can be used in a variety of different applications in the automotive industry including sensors, actuators, control circuitry and communications hardware. Telecom: It can be used for surge protection in telecoms equipment including routers, switches, radio receivers, electronic cables, and much more. Consumer: It can also be used in consumer electronics products such as smartphones, tablets, and other electronic devices. Data Communications: Additionally, it is often used in data communications equipment as a protection against ESD events.

Working Principle

The ESDALC7-1BF4 is designed to protect sensitive circuits from voltage transients by using a unique protection circuit. This circuit contains two diodes, which are connected in series and in reverse polarity across the sensitive circuitry. When subjected to an ESD ( Electro-Static Discharge) , the ESDALC7-1BF4 will absorb the energy and rapidly limit the voltage spike. It does this by having both the anode and the cathode, absorb the voltage transient as it is being discharged and thus, prevent any damage to the surrounding circuitry. In addition, the ESDALC7-1BF4 is designed to absorb up to 315 volts without any damage to the device itself.

Conclusion

The ESDALC7-1BF4 is a special kind of TVS (Transient Voltage Suppression) diode which is mainly used in a variety of different applications across the automotive, telecom, consumer and data communication markets. This device is highly effective in protecting circuits from voltage transients which can be caused by either electrical noise from the environment or by electrostatic discharge. It is designed with a specialized protection circuit which consists of two diodes connected in series and in reverse polarity. This allows the device to absorb the energy from the transient and rapidly limit the voltage spike, thereby preventing any further damage to surrounding circuitry. Furthermore, the ESDALC7-1BF4 is rated to absorb up to 315V without any damage to itself.
