Diodes have become an integral component in many electronic circuits, and the BZD27C20PW zener diode is no exception. When used as a voltage reference, the BZD27C20PW allows a defined voltage to be maintained. It can also be used in the protection of circuits from unanticipated high voltages by limiting the voltage to a safe level.

The BZD27C20PW is a single zener diode and is available in a wide range of breakdown voltages ranging from 5.1V to 68V. The BZD27C20PW is a temperature-sensitive device, with a temperature coefficient of 8.5mV/°C. The device has maximum power dissipation of 3W and a maximum surge current of 18A.

The BZD27C20PW has a wide range of application fields. It can be used as a voltage regulator in battery power systems, to regulate line voltages to protect delicate circuitry. It can also be used as a voltage reference in digital logic circuits. In audio applications it can be used to maintain low distortion in amplifier circuits.

The working principle of the BZD27C20PW is based on the principle of vacuum breakdown. When the voltage across the BZD27C20PW is greater than its breakdown voltage, a field of electrons is formed, allowing current to flow through the diode. Current flow, however, is limited to a relatively safe level. As the voltage across the diode increases, so does the current. At a certain point, the device reaches its maximum power dissipation limit, and the current will no longer increase.

The BZD27C20PW is a temperature-sensitive device, so when temperature rises above its maximum operating temperature, the breakdown voltage and power dissipation limit will decrease. To prevent heat build-up, it is important to use a heat sink when using the BZD27C20PW.

In summary, the BZD27C20PW is a single zener diode and is available in a wide range of breakdown voltages. It has a wide range of application fields and is based on the principle of vacuum breakdown. The device is temperature-sensitive, with a temperature coefficient of 8.5mV/°C, and has a maximum power dissipation of 3W and a maximum surge current of 18A. It is important to use a heat sink when using the BZD27C20PW in order to prevent heat build-up.
