1N5354AE3/TR8

Overview

The Microchip Technology 1N5354AE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by Microsemi's Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 17 V with a standard tolerance of ±10%, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial-lead package. Electrical characteristics include a maximum reverse current of 1.0 µA and a dynamic impedance of 2.5 Ω.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole applications
• Moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the component origin as this part number originates from the Microsemi Scottsdale Division, which has been acquired by Microchip Technology. Confirm that the RoHS compliant 'e3' suffix matches environmental requirements and ensure the 'TR8' tape and reel packaging aligns with automated assembly specifications before procurement.

Selection Notes

Select this component when a 17 V regulation point with ±10% tolerance is required in a 5-watt power dissipation environment. Ensure adequate heat sinking is provided to maintain operation below the maximum junction temperature. Verify that the axial lead configuration fits the mechanical constraints of the target printed circuit board layout.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The specific 'A' suffix denotes a ±10% voltage tolerance, distinguishing it from tighter tolerance variants like the 'C' (±2%) or 'D' (±1%) suffixes available within the same product family.

Replacement Considerations

Cross-reference other manufacturers' 5-watt Zener diodes rated at 17 V with ±10% tolerance. Verify compatibility regarding thermal resistance, package dimensions, and maximum surge current ratings to ensure functional equivalence in the existing design.
