Overview
The Central Semiconductor Corp 1N5305 BK PBFREE is a silicon planar power Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 75 V with a tolerance of ±5%. The device is rated for a maximum DC power dissipation of 5 W at an ambient temperature of 25°C, de-rating linearly above this threshold. It utilizes the DO-201AE (DO-204AA) axial leaded package and supports a maximum operating junction temperature of +175°C. The component is RoHS compliant and manufactured without halogens.
Feature Summary
- High power dissipation capability suitable for robust voltage regulation tasks
- Wide operating temperature range extending to high thermal limits
- Axial leaded construction facilitating through-hole mounting
Applications
- General purpose voltage reference circuits
- Overvoltage protection in power supplies
- Clamping applications in electronic systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm compliance with environmental directives such as RoHS and REACH. Confirm that the axial lead form factor matches the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a 75 V regulation point is required with significant power handling capacity. Ensure the circuit design accounts for the necessary heat sinking or airflow to maintain junction temperatures within the specified +175°C limit during continuous operation.
Part Context
This part belongs to the standard 1N53xx series of high-power Zener diodes produced by Central Semiconductor. These components are widely utilized in industrial and commercial electronics where reliable voltage clamping and regulation are critical under varying load conditions.
Replacement Considerations
Cross-reference with other manufacturers' DO-201 packaged 75 V 5 W Zener diodes. Verify pinout compatibility and thermal resistance characteristics to ensure equivalent performance in existing designs.
