1N5346B BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N5346B BK TIN/LEAD is a silicon planar power Zener diode designed for stabilizing and clipping circuits. It features a nominal Zener voltage of 9.1 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates in a through-hole axial DO-201 package and dissipates up to 5 W of power. It supports a maximum junction temperature of 200°C and includes tin/lead plating as specified by the ordering suffix.

Feature Summary

• Silicon planar construction for high-power applications
• Standardized ±5% voltage tolerance for precision regulation
• Robust thermal performance supporting high junction temperatures

Applications

• High-power voltage stabilization circuits
• Signal clipping applications requiring robust power handling
• Industrial power supply regulation

Procurement Notes

Verify that the specific part number matches the required tin/lead plating configuration, as this affects RoHS compliance status. Confirm availability directly with Central Semiconductor or authorized distributors, as standard packaged devices may be subject to discontinuation notices without prior warning. Ensure the design accommodates the specified 5 W power dissipation and axial leaded form factor.

Selection Notes

Select this component when a 9.1 V reference with tight ±5% tolerance is required in a high-power environment. The DO-201 axial package provides superior heat dissipation compared to smaller surface-mount alternatives. Verify that the operating junction temperature range aligns with the system's thermal constraints and that the tin/lead termination meets the assembly process requirements.

Part Context

This device belongs to the 1N53xx series of power Zener diodes manufactured by Central Semiconductor Corp. The series is characterized by its ability to handle significant power dissipation in an axial leaded package. The 'B' designation specifically denotes the tighter voltage tolerance band available within this product line.

Replacement Considerations

Central Semiconductor lists CZ5346B as the replacement for the discontinued 1N5346B.
