Here are some common packaging models and key information for small glass voltage regulators:
1. BZX55C series: This series of diodes is packaged in a Φ 3 size and has a wide range of voltage regulation values, ranging from 2.4V to 440V, with a power of 0.5W. It is suitable for circuits with strict size requirements.
2. BZX85C series: This series of diodes adopts a Φ 4 size package, with a voltage regulation range from 2.7V to 400V and a power of 1.0W. Compared with the BZX55C series, it has a higher power tolerance.
3. 1N4728A series: This series of diodes adopts DO-35 packaging, with a voltage regulation range of 3.3V to 200V and a power of 1.0W. The DO-35 packaging enables the diode to have better heat dissipation performance, making it suitable for circuits that require higher voltage regulation and power.
