1N5306-20 BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N5306-20 BK TIN/LEAD is a silicon planar power rectifier designed for high-voltage applications. It features a maximum repetitive peak reverse voltage of 20 kV and a continuous forward current rating of 1.0 A. The device utilizes a glass passivated junction to ensure stability under harsh conditions. Key electrical specifications include a non-repetitive peak forward surge current of 40 A at 8.3 ms and a maximum RMS reverse voltage of 14,000 V. The component is housed in a DO-5 axial leaded package, suitable for through-hole mounting in industrial and high-voltage power supply circuits.

Feature Summary

• High voltage capability with a 20 kV repetitive peak reverse voltage rating
• Glass passivated junction construction for enhanced environmental stability
• Robust surge handling with a 40 A non-repetitive peak forward surge current capacity

Applications

• High-voltage DC power supply rectification
• Industrial control systems requiring high isolation voltages
• X-ray equipment and ion generator power stages

Procurement Notes

Verify the specific suffix -20 BK TIN/LEAD against the manufacturer datasheet to confirm the 20 kV rating and tin/lead plating specification. Ensure compliance with RoHS directives if applicable, as tin/lead variants may differ from standard lead-free offerings. Confirm package dimensions match the DO-5 footprint before integration into existing PCB layouts or chassis designs.

Selection Notes

Select this component when circuit requirements demand extreme reverse voltage blocking capabilities exceeding standard rectifier limits. The 1.0 A current rating supports moderate load currents while maintaining low leakage characteristics. Consider thermal management strategies for the DO-5 package, as heat dissipation relies on lead conduction rather than a dedicated heatsink tab found in larger packages.

Part Context

This part belongs to the 1N530x series of high-voltage rectifiers manufactured by Central Semiconductor. The series is characterized by its ability to handle kilovolt-level potentials, making it distinct from general-purpose diodes. The -20 designation specifically indicates the 20,000 V breakdown threshold, differentiating it from lower voltage variants within the same product family.

Replacement Considerations

Direct substitutes must match the 20 kV PIV and 1.0 A average forward current ratings. Verify that alternative components offer comparable surge current capabilities and utilize similar axial leaded packaging for mechanical compatibility. Cross-reference datasheets for reverse recovery time and leakage current specifications to ensure equivalent performance in high-voltage switching environments.
