1N5350B/TR8

Overview

The Microchip Technology 1N5350B/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 13 V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum dynamic impedance of 2.5 Ω and a maximum reverse current of 1.0 μA at 9.9 V. The device utilizes an axial-lead T-18 package and includes a TR suffix for tape-and-reel packaging.

Feature Summary

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

Applications

• Voltage regulation over broad operating currents
• High surge stress environments
• Temperature-stable reference circuits

Procurement Notes

Verify the specific manufacturer origin, as the part number originates from Microsemi which was acquired by Microchip Technology. Confirm that the 'TR' suffix correctly indicates tape-and-reel packaging per EIA-296 standards. Ensure the component meets required moisture classification Level 1 specifications without dry pack requirements.

Selection Notes

Select this component when a 13 V regulation point is required with a 5 W power dissipation capacity. The B suffix ensures a standard ±5% voltage tolerance. Consider the thermal resistance characteristics and derating curves if operating near maximum limits or on FR4 printed circuit boards.

Part Context

This component belongs to the JEDEC registered 1N5333-5388B series of axial-leaded 5.0 watt Zeners. The series covers a wide selection of voltages from 3.3 to 200 volts. The 1N5350B variant specifically targets the 13 V regulation requirement within this established product family.

Replacement Considerations

Surface mount equivalents are available as SMBJ5350B or SMBG5350B. RoHS compliant devices can be identified by adding the e3 suffix to the part number.
