1N5346B TR TIN/LEAD

Overview

The Central Semiconductor Corp 1N5346B TR TIN/LEAD is a glass-passivated junction silicon Zener diode designed for through-hole mounting in the DO-201AE (DO-15) axial package. It provides a nominal Zener voltage of 9.1 V with a 5% tolerance and a maximum power dissipation of 5 W at 75°C ambient temperature. The device features a low-inductance construction, built-in strain relief, and operates within a temperature range of -65°C to +200°C.

Feature Summary

• Glass passivated junction for enhanced reliability
• Built-in strain relief for mechanical stability
• Low inductance design for high-frequency performance

Applications

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

Procurement Notes

Verify that the ordering suffix 'TIN/LEAD' is correctly applied to request Tin/Lead plated devices, as this specifies the terminal finish. Confirm compliance with environmental regulations if lead-free alternatives are required. Ensure the component meets specific screening requirements for your application.

Selection Notes

Select this component when a 5 W axial Zener diode with a 9.1 V breakdown voltage is needed. Consider the DO-201AE package size and the operating temperature range up to 200°C. Verify that the 5% voltage tolerance aligns with circuit precision requirements.

Part Context

This part belongs to the 1N5333B-1N5388B series of high-power Zener diodes manufactured by Central Semiconductor Corp. These components utilize a molded plastic case over a passivated junction, offering robust performance in demanding electronic environments.
