Diodes - Zener - Single: BZX84-B2V4, 215

The BZX84-B2V4,215 Zener single diode by NXP is a silicon planar, voltage regulator diode. Its main uses include miniaturized electronics, especially where space is at a premium and a minimal number of components is desired. It has a high stability voltage regulation across a wide variety of temperature and current conditions, making it suitable for use in industrial and telecommunications environments. The diode is packaged in a SOT-23 body, with a Cathode Marking of ‘C’.

The Zener Voltage of the BZX84-B2V4,215 is 215 Volts. This means that when the reverse voltage is at or below the Zener Voltage, the reverse current will remain constant. The Maximum Reverse Power Dissipation of this diode is 375mW, the Maximum Reverse Voltage is 200V, and the Maximum Forward Voltage is 1.2V. The diode also has a Peak Pulse Forward Current of 100mA. It also has a thermal resistance of 300mΩ and a clamping voltage of 241V.

The working principle of the BZX84-B2V4,215 Zener Single Diode can be best explained by considering it as a silicon junction diode that has one region doped to achieve a very narrow depletion region - this region is known as the Zener region. Current does not flow through the diode until the reverse voltage is greater than the Zener Voltage. When the reverse voltage reaches this level, the diode breaks down and current starts to flow through it in the reverse direction. The amount of current that flows through the diode depends on the Zener breakdown voltage, which is determined by the amount of doping in the Zener region. Because the Zener voltage is constant, the current that flows through the diode is also constant.

The main application area of the BZX84-B2V4,215 Zener Single Diode is in the production and stabilization of regulated DC voltages. This diode is especially useful in regulated power supplies, voltage regulators, and other circuits where precise voltages need to be maintained. It is also useful in applications such as LED backlighting of LCDs and for voltage clamping and over-voltage protection. The low capacitance of this diode also makes it suitable for applications such as data transmission and radio frequency (RF) applications. As it is a low-cost, highly efficient diode with a long service life, the BZX84-B2V4,115 Zener Single Diode is in common use wherever precision regulated DC voltages are required.
