1N3994AE3

The 1N3994AE3 is a Zener diode manufactured by ON Semiconductor. This device offers maximum current of 200 mA and maximum reverse voltage of 79V. Its maximum power dissipation is 500mW.This diode is primarily used for voltage regulation, providing a nice and accurate low-power voltage regulation for electronic devices. It is also used for reversed biasing applications, such as in switching power supplies, along with RF and ESD protection circuits.As a Zener diode, the 1N3994AE3 acts as a basic diode when a forward current is applied to it. With this device, a voltage of VZ (Voltage Zener) can be established by adjusting the current passing through it in the reverse direction.The 1N3994AE3’s reverse current is dependent on the applied voltage, and it will cause a predictable voltage at the device’s anode. This voltage can range from 5.1V (VZ) to 79V (VR), and it will remain in tolerance so long as the diode is kept within its specified operating current and power ratings.The 1N3994AE3 is available in a DO-35 package with a maximum junction temperature of 175°C. This diode can operate over a range of temperature from -65°C to +175°C with reliable performance. It is RoHS compliant and meets halogen-free requirements.The 1N3994AE3 is a useful and reliable device for regulating voltage in any circuit application. It can not only be used as a voltage regulation device, but also as a protection device, providing a safe and accurate current flow in any given circuit.
