The Central Semiconductor Corp 1N5228B TR PBFREE is a silicon Zener diode designed for voltage regulation in industrial, commercial, entertainment, and computer applications. It features a nominal Zener voltage of 3.9 V with a tolerance of ±5%. The device operates within a power dissipation rating of 500 mW at 75°C ambient temperature and supports junction temperatures from -65°C to +200°C. Electrical characteristics include a maximum reverse current of 10 µA at 1.0 V and a maximum Zener impedance of 23 Ω at the test current of 20 mA.
Verify the specific ordering suffix against manufacturer documentation to confirm compliance requirements. Confirm package type and marking codes match design specifications. Check for any product lifecycle notices or discontinuation updates directly from the manufacturer before finalizing procurement plans.
Select this component based on the required nominal voltage and tight tolerance specifications. Ensure the thermal environment allows for the specified 500 mW power dissipation limit. Verify that the package style aligns with the intended PCB layout and mounting requirements for the target application.
This part belongs to the 1N5221B through 1N5278B series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a wide voltage range from 2.4 V to 170 V, all housed in the DO-35 axial leaded package. The 'B' suffix specifically denotes a ±5% voltage tolerance standard across the entire family.
