Hello, Please ask a question about CZRL5228B Datasheet
# Example questions:
➢ What is the zener impedance testing methodology described in the documentation, and why is it measured in that way?
➢ Explain the significance of these conditions for accurate zener diode characterization.
➢ What is the maximum dc reverse voltage (vr) for the czrl5240b diode?

| Description | Surface Mount Zener Diodes |
1. Product Series:
️· Series: CZRL52xx (where xx is a two-digit number, e.g., CZRL5225B, CZRL5267B)
️· Type: Surface Mount Zener Diodes
2. Key Specifications (for each diode in the series - see table at the end for a full breakdown):
️· Zener Voltage (Vz): Ranges from 3V to 75V.
️· Zener Current (IZT): Typically 20mA, but varies for higher voltage diodes (e.g., 17mA for 75V).
️· Test Current (IZT): As noted above, the current used to measure the Zener voltage.
️· Zener Impedance (ZZT/ZZK): This is the impedance at the Zener voltage (ZZT) and at a test current of 0.25mA (ZZK). Values vary significantly by diode.
️· Reverse Leakage Current (IR): Very low values, ranging from 0.1µA to 50µA.
️· Reverse Voltage (VR): Indicates the maximum reverse voltage the diode can withstand.
️· Maximum Power Dissipation: Not explicitly stated, but implied to be within the capabilities of the surface mount package.
3. Notes and Conditions:
️· Zener Impedance Measurement: The stated impedance is determined using a 1kHz AC voltage superimposed on the Zener current.
️· Validity: Specifications are valid when electrodes are kept at a distance of 10mm from the diode's case.
️· Testing Conditions: The testing was performed under thermal equilibrium and DC test conditions.
