1N5284 BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N5284 BK TIN/LEAD is a current regulation diode designed for through-hole mounting in the DO-35-2 package. It features a maximum peak operating voltage of 100 V and a power dissipation rating of 600 mW. The device regulates current at approximately 276 µA with a maximum regulator current of 1.15 mA and a minimum dynamic impedance of 800 kΩ. It operates within a temperature range of -65°C to +200°C.

Feature Summary

• Provides stable current regulation for circuit applications
• Supports high peak operating voltages up to 100 V
• Features high dynamic impedance for effective current control

Applications

• Current limiting circuits
• Biasing networks
• Constant current sources

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm lead-free or tin/lead compliance status, as variations exist within the product line. Confirm that the DO-35-2 axial package matches your PCB footprint requirements. Ensure the 600 mW power dissipation rating is sufficient for your thermal environment. Check for any recent manufacturing changes or obsolescence notices directly from Central Semiconductor before finalizing procurement.

Selection Notes

Select this component when a precise low-current regulation value near 276 µA is required. The high dynamic impedance ensures stable performance under varying load conditions. Verify that the 100 V peak voltage rating exceeds the maximum transient voltages present in the application. Consider the through-hole mounting style if surface mount alternatives are not suitable for the mechanical constraints.

Part Context

This part belongs to the 1N52xx series of current regulation diodes manufactured by Central Semiconductor. These devices utilize Zener breakdown principles to maintain a constant current flow regardless of voltage fluctuations across the device. The series offers various current values and voltage ratings to suit different electronic design needs.

Replacement Considerations

Cross-reference with other 1N52xx series current regulation diodes from Central Semiconductor or equivalent manufacturers offering similar 276 µA regulation and 100 V ratings. Ensure pinout compatibility and thermal characteristics match the original design specifications.
