1N5356CE3/TR12

Overview

The Microchip Technology 1N5356CE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 19 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates in an axial T-18 package and supports tape-and-reel packaging via the 'TR12' suffix. Electrical characteristics include a maximum reverse current of 0.5 µA and a dynamic impedance of 3.0 Ω.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and exhibits minimal voltage changes versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High maximum DC current applications with adequate heat sinking
• Equipment needing robust performance against high surge stresses

Procurement Notes

Verify the component origin as this part originates from the Microsemi Scottsdale Division, now part of Microchip Technology. Confirm that the specific ordering suffixes correspond to the required RoHS compliance (e3) and tape-and-reel packaging (TR). Ensure the C suffix matches the necessary ±2% voltage tolerance for your design requirements before procurement.

Selection Notes

Select this component when a precise 19 V reference is needed with tighter than standard tolerances. The 5-watt rating allows operation at high currents if sufficient thermal management is provided. Consider the T-18 package dimensions for PCB layout and verify that the lead length meets the specified thermal resistance calculations for junction-to-lead or ambient cooling.

Part Context

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

Replacement Considerations

Compatible substitutes include other 1N5356 variants with matching electrical ratings, such as the 1N5356B (±5% tolerance) or 1N5356D (±1% tolerance), provided the package and power dissipation requirements are met.
