Diodes - Zener - Single: SJPZ-N33VL Application Field and Working Principle

The SJPZ-N33VL diode is a popular voltage regulator diode designed to protect sensitive circuitry by clamping or regulating voltages to a specified level. This Zener diode is widely used in active device protection, power surge protection and voltage regulation applications. It is mainly used in medical equipment, power systems, household appliances and communication equipment.

The SJPZ-N33VL is a surface mount Zener diode that can have its voltage clamped to 33 volts. It is commonly used in high voltage power supplies and highly sensitive circuits, where supply currents and voltages vary significantly due to changing loads, or in fast switching applications where the diode can be used as a voltage transient suppressor. The diode is specified with a breakdown voltage of 33 V, at a nominal current rating of 500 mA.

Operating Principle of SJPZ-N33VL Diode

When the reverse bias voltage applied to the SJPZ-N33VL diode reaches its rated breakdown voltage of 33 V, the diode will begin conducting in the reverse direction. This causes the current to flow through the diode without any change in the voltage indication. In Zener diodes, at breakdown voltage, the device operates in the Avalanche Breakdown Region. The current flowing through the diode at this voltage is known as the zener current and is limited only by the external resistance.

Above the breakdown voltage the current is constant and the voltage drop across the device is equal to the breakdown voltage. As the voltage across the device is increased, the current increases exponentially due to the increased field strength between the diode junction. As the voltage is increased further, the junction starts to break down and become forward biased, thus allowing the current flow in the forward direction.

Other Essential Features of SJPZ-N33VL Diode

The SJPZ-N33VL diode also has an excellent surge current rating, which allows it to handle relatively high current loads. It also has a high immunity to vibrations, so it is well suited for rugged environments. Its maximum working temperature is 1 175 degrees Celsius and it can withstand a short circuit of up to 3 A for a period of 8 hours, which makes it suitable for military and industrial applications. The diode also has a very low leakage current of 0.1 micro amp and a linearly increasing reverse recovery time of 5 microseconds.

The SJPZ-N33VL diode is available in an 8 pin DIP package, so it is easy to install into the circuit without any special tools. It is also RoHS compliant, so it is certified to be lead-free, environmentally sound and safe for use in all types of applications. The diode is extremely affordable, making it a great choice for those who are looking to build their own voltage regulator. It is also highly reliable and provides superior performance even in extreme conditions.
