WEET Zener Diode BZV55C75 Main parameters
Voltage stabilization value (Vz): nominal 75V, tolerance ± 5%, actual range approximately 71.25V to 78.75V.
Dissipative power (Pd): The common specification is 500mW (some data indicate 400MW, depending on the brand).
Packaging: SOD-80C/Mini MELF (LL-34), glass cylinder, with cap welding points at both ends, surface mount.
Reverse leakage current (Ir): approximately 50nA-10nA @ 53V-56V.
Working temperature range: -65 ℃ to+175 ℃ (some brands have an upper limit of+200 ℃).
Dynamic impedance (Zzt): about 170 Ω~255 Ω, slightly different brands.
Key Instructions
The "C" in the model represents a voltage regulation tolerance of ± 5% (± 2% for BZV55B series), which needs to be distinguished when selecting.
This series covers the entire range of 2.4V to 75V, with BZV55C75 being the highest voltage regulator among them.
Mainly used as a low-voltage stabilizer or voltage reference, commonly found in circuits such as adapters and DC/DC converters.
Attention to use
75V is the breakdown voltage, not the maximum withstand voltage. The actual operating voltage should be lower than this value.
When using, a series current limiting resistor should be used to control the current and avoid damage caused by power consumption exceeding 500mW.
