The PD3Z284C36-7 is a single zener diode from a family of such devices developed to provide an effective way to protect sensitive components and circuitry by regulating a DC voltage. This device is housed in a 2-lead axial package, and is characterized by its low leakage, low capacitance, low power dissipation and a wide range of potential applications.

Application Field

The PD3Z284C36-7 is primarily used to provide an efficient and reliable form of circuit protection as well as protection from negative transients. It is most commonly found in consumer electronics, automotive, military and aerospace systems, power supplies, and telecommunications equipment.

The PD3Z284C36-7 is also suitable for protecting graphical processor units. GPUs are very sensitive devices and are liable to suffer permanent damage if exposed to high voltage transients. The PD3Z284C36-7 can be used to provide a sturdy and dependable form of protection to GPUs.

It is also suitable for voltage-clamping applications such as those in the circuit protection of data buses. These are special digital signal lines that are subject to transient outages or wide voltage swings to the power trains – due to transients, the data communication is disrupted. Using the PD3Z284C36-7 can guard against this, as it provides over-voltage protection.

Working Principle

The PD3Z284C36-7 is a single zener diode that is designed to regulate a voltage up to 36 Volts DC. It works by allowing current to flow passively in one direction and blocking it from flowing the other, the current flow is only uni-directional and the device can provide zener breakdown protection. This means that once the voltage reaches a specific level, the ‘zener’ action of the PD3Z284C36-7 kicks in to stabilize it by not allowing any further increases. The breakdown voltage is adjustable, to allow rising voltage values to reach tolerated levels.

The PD3Z284C36-7 is also able to provide transient protection by clamping voltage spikes and peaks. This is achieved through its ultra low leakage capability and its low capacitance, which keeps capacitive coupling of transient signals to a minimum. When used in parallel with a bypass diode and filter, it enables a power supply to reject any disturbances to the line.

Overall, the PD3Z284C36-7 is designed for use in applications which require protection from over-voltage transients, as well as providing voltage stabilization. With its low leakage current, low capacitance and wide range of potential applications, this device is perfectly suited for protecting sensitive components and built in circuitry.
