Introduction to BZX84C4V3LFHT116

The BZX84C4V3LFHT116 is a small signal Zener diode from Diodes Incorporated. It is a single-diode device packaged in a SOD-123 package. This diode is designed to operate over an extended temperature range, from -65°C to +150°C.

Application Fields

The BZX84C4V3LFHT116 is suitable for use in a wide range of applications. It is primarily used as an overvoltage protection device, as it has a very sharp breakdown voltage and low on-state resistance. It can also be used as a voltage reference, voltage limiter, and low-power switch, as well as in linear regulator systems.

Working Principle

The BZX84C4V3LFHT116 is a Zener diode. When forward biased, the diode allows current to flow. When reverse biased, the diode is in its blocking mode, where current cannot flow. The Zener voltage of the diode is the voltage at which the diode conducts in reverse bias as soon as a certain threshold voltage is exceeded. At this point, the diode breakdown resistance begins to decrease rapidly and becomes extremely low. The breakdown voltage of the BZX84C4V3LFHT116 is 4.3V, with a maximum reverse current of 47nA. The maximum power dissipation is 500 mW and the maximum operating temperature is 150°C.

Conclusion

The BZX84C4V3LFHT116 is a versatile diode suitable for a wide range of applications. It has a sharp breakdown voltage and very low on-state resistance, making it an ideal protection device. It can also be used in other applications such as voltage reference, voltage limiter, and low-power switch. As such, it is well suited for a variety of applications.
