1N5356CE3/TR8

Overview

The Microchip Technology 1N5356CE3/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation with a nominal Zener voltage of 19V and a tight tolerance of ±2%, indicated by the 'C' suffix. The device features an axial-lead T-18 package, operates within a temperature range of -65°C to +150°C, and includes RoHS compliance via the 'e3' suffix. It is supplied in tape and reel packaging.

Feature Summary

• Provides precise voltage regulation with ±2% tolerance for stable reference applications
• Capable of handling high surge stresses and steady-state power dissipation up to 5 watts
• Features flexible axial-lead mounting terminals suitable for through-hole assembly

Applications

• Voltage regulation circuits requiring high precision
• Power supply reference standards
• Protection against transient voltage spikes

Procurement Notes

Verify the specific manufacturer origin, as the 1N5356 series was originally a Microsemi product now under Microchip Technology. Confirm that the 'TR8' suffix corresponds to the required tape and reel quantity and packaging standard. Ensure the RoHS compliant 'e3' designation matches environmental requirements for the target assembly process.

Selection Notes

Select this component when a 19V Zener reference with tighter than standard ±5% tolerance is required. The 5W power rating allows for operation at higher currents compared to lower-power equivalents. Consider the thermal resistance characteristics and heat sinking requirements for maintaining performance within the specified operating temperature range.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The 'C' suffix specifically denotes the ±2% voltage tolerance variant, distinguishing it from standard B (±5%) or A (±10%) tolerance devices within the same power class.

Replacement Considerations

Direct substitutes include other 1N5356 variants with different tolerances (e.g., 1N5356A for ±10%, 1N5356B for ±5%) if precision requirements allow. Surface mount equivalents such as SMBJ5356 or SMBG5356 may be used where footprint changes are acceptable.
