  The BZX85C9V1 is a members of the diode, zener, single category. This diode has a 2.4 V zener breakdown, resulting in high power handling capability, low noise and high operating temperature. It is RoHS compliant, making it suitable for a wide range of applications.

  The BZX85C9V1 is used primarily in voltage-controlled circuits such as voltage regulators, voltage multipliers and high-voltage/high-power supplies. It is also commonly used in switching power supplies, automotive alternators and home appliance controllers for over-voltage protection.

  The BZX85C9V1 has a low dynamic impedance and a low thermal coefficient. It has excellent high temperature stability and good surge current capability. The device also has a high power rating of up to 1.5 watts.

  The BZX85C9V1\'s working principle is based on the Zener diode breakdown effect, also known as Avalanche breakdown. At a certain reverse bias voltage (the zener voltage), this diode experiences massive current flow due to the avalanche effect which increases the junction temperature. This increases the carrier concentration in the depletion region, further increasing the Zener current. This results in a stable voltage between the diode’s leads, regulation of the voltage is dependent on the zener voltage.

  The BZX85C9V1 is available in a DO-35 package and is RoHS compliant for lower lead emissions. It is lead free-compatible, making it suitable for use in lead-free solders. The device has an operating temperature range from -55°C to +150°C, making it suitable for both consumer and industrial applications.

  In summary, the BZX85C9V1 is a low-power zener diode with a 2.4-V zener breakdown voltage. It is primarily used in applications that require voltage regulation, such as switching power supplies, automotive alternators, voltage regulators, voltage multipliers and high-voltage/high-power supplies. It has excellent high temperature stability and good surge current capability, along with a wide operating temperature range and RoHS compliance.
