BZD17C36P-E3-08 application field and working principle

The BZD17C36P-E3-08 is a type of Zener diode. It is mainly used for voltage regulation and clamping in most applications. It can also be used in voltage-dependent resistors for transient suppression.

The characteristic of a Zener diode is its ability to conduct current in reverse bias conditions when the Zener voltage is exceeded. This process of breakdown is known as Zener breakdown. The reverse biased Zener junction displays a nearly flat voltage-current characteristic with a very small slope. The small amount of current that passes the junction is the sum of the leakage current and the Zener current. The Zener current is not constant, but depends on the temperature. The breakdown voltage, which is almost constant up to a certain current, is the nominal Zener voltage or Zener voltage, as it is marked on the diode specification.

The BZD17C36P-E3-08 is a single Zener diode with a nominal Zener voltage of 36V and a maximum reverse current of 12µA through a power dissipation of 500mW. The maximum peak pulse current rating for the diode is 150mA with a maximum surge current of 250mA. The diode has a maximum operating temperature of 175℃ and a reverse recovery time of 50ns.

The most common use of the BZD17C36P-E3-08 is as a voltage regulator in a simple circuit. In such a circuit, the diode is placed between the power source and the load, with the anode being connected to the power source and the cathode to the load. This arrangement ensures that the voltage across the load stays within the Zener voltage range, no matter what the variation in the input or output voltage. As the input voltage increases, the Zener diode begins to conduct, resulting in a stable voltage across the load. The diode can also be used as a clamp for transient protection. When the transient voltage exceeds the Zener voltage, the diode diverts the voltage away from the load, thus protecting it from the transient.

The BZD17C36P-E3-08 is a very versatile diode and can be used for many purposes such as voltage regulation, overvoltage protection, and shunting. Its low leakage and reverse current make it an excellent choice for many applications.
