CDLL5246 Application Field and Working Principle

CDLL5246 is a single Zener diode manufactured by Microsemi Corporation. Its purpose is to provide a safe and convenient way to provide circuit protection against voltage variations in the power source, which can be caused by electrostatic discharge, voltage spikes or transients. It is designed to dissipate up to 500mW of power and can withstand a maximum reverse voltage of 5.6V.

Applications

The CDLL5246 is typically used in automotive, telecom and medical applications and is available in both thru-hole and surface mount packages. In automotive applications, it is typically used as a protection circuit for components such as fuses and relays. In telecom and medical applications, it is most commonly used for surge protection and EMI/RFI filtering. It is frequently used in switch-mode power supplies, for protection against spikes and transients generated during switching. Additionally, it can be used in combination with transistors and BJTs to create a switchable current source.

Working Principle

The CDLL5246 is a single Zener diode, which is an electronic component that permits current to pass in one direction only and blocks it when the voltage between its terminals exceeds a specified level. When forward-biased, the diode behaves as a usual diode in that it will pass a current when the voltage between its terminals is increased to a certain level. When reverse-biased, the diode can be set to "breakdown" at a specific voltage, such that if the voltage increases above this level, it will conduct a large current while maintaining that voltage across its terminals. This breakdown voltage level is set by the designer, and is typically established through a constant current source.

The CDLL5246 is designed to trigger breakdown at a voltage of 5.6V. When the voltage between its terminals reaches this level, it will trigger the breakdown and become highly conductive. This enables the diode to absorb any voltage spikes or transients without damaging the underlying circuitry. The diode will dissipate the energy of any excessive voltage that is applied to its terminals, thereby protecting the rest of the circuit.

Conclusion

In conclusion, the CDLL5246 is a single Zener diode designed for use in automotive, telecom and medical applications. It is designed to trigger breakdown at a voltage of 5.6V, and is capable of dissipating up to 500mW of energy to protect underlying circuitry from voltage surges and transients. It is an ideal protection device for automotive and telecom components and is widely used in switch-mode power supplies.
