1N5350BE3/TR13

Overview

The Microchip Technology 1N5350BE3/TR13 is a silicon Zener diode with a nominal voltage of 13 V and a maximum power dissipation of 5 W. It features a ±5% tolerance, indicated by the 'B' suffix, and operates within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes RoHS compliance via the 'e3' suffix.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Applications

• Voltage regulation circuits requiring 5W power handling
• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic systems

Procurement Notes

Verify that the component matches the specified JEDEC registered series and confirms the presence of the e3 suffix for lead-free compliance. Ensure the TR13 designation aligns with reel packaging requirements. Confirm the B suffix corresponds to the required ±5% voltage tolerance before finalizing procurement orders.

Selection Notes

Select this component when a 13V Zener reference with 5W capability is needed. The T-18 package supports high DC currents if adequate heat sinking is provided. Consider thermal resistance specifications for derating calculations based on the specific mounting method used in the design.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. These devices are designed for applications requiring robust voltage regulation and high surge current handling capabilities within standard axial-lead configurations.

Replacement Considerations

Direct replacements include other manufacturers' 1N5350 variants meeting the same electrical specifications. Verify pinout compatibility and ensure the replacement part supports the required 5W power dissipation and 13V nominal voltage.
