1N5351B BK

Overview

The Central Semiconductor Corp 1N5351B BK is a silicon Zener diode housed in a DO-201AE plastic package. It provides a nominal voltage of 14V with a tolerance of ±10%. The device supports a maximum DC power dissipation of 5W and operates within a temperature range of -55°C to +150°C. The suffix BK indicates bulk packaging.

Feature Summary

• Utilizes a molded plastic case with built-in strain relief for mechanical durability
• Features solder-plated terminals compliant with MIL-STD-750 Method 2026
• Constructed from unidirectional silicon material

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation, as plating options such as TIN/LEAD or PBFREE alter the part number. Confirm that the BK suffix corresponds to bulk packaging rather than tape and reel formats. Ensure compliance with RoHS directives if lead-free requirements are necessary for the assembly process.

Selection Notes

Select this component when a 5W power rating and 14V breakdown voltage are required in a through-hole configuration. The DO-201AE package offers robust thermal performance compared to smaller surface mount alternatives. Verify that the ±10% tolerance aligns with the circuit's precision requirements before finalizing the design.

Part Context

This device belongs to the 1N53xx series of high-power Zener diodes manufactured by Central Semiconductor. These components are designed for applications requiring stable voltage reference points under significant power loads. The series utilizes standard JEDEC DO-201AE casing for reliable through-hole mounting.

Replacement Considerations

The datasheet lists CZ5351B as the replacement for the 1N5351B variant.
