1N5365C/TR12

Overview

The Microchip Technology 1N5365C/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation applications. It features a nominal Zener voltage of 36 V with a tight ±2% tolerance, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and utilizes an axial T-18 package. Electrical characteristics include a maximum dynamic impedance of 11 Ohms at a test current of 30 mA, a maximum reverse leakage current of 0.5 µA, and a maximum regulator current of 3.3 A.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features low thermal resistance design suitable for high DC currents with adequate heat sinking
• Offers flexible axial-lead mounting terminals in a void-free transfer molded epoxy body

Applications

• Voltage regulation circuits requiring precise tolerance
• Power supply reference standards
• Protection against overvoltage conditions

Procurement Notes

Verify component authenticity through authorized channels as this part originates from the Microsemi Scottsdale Division, now part of Microchip Technology. Confirm RoHS compliance status via the e3 suffix designation if required. Ensure proper handling procedures are followed due to the plastic encapsulated construction. Review datasheet specifications regarding thermal derating curves before implementation to ensure reliable operation under specific load conditions.

Selection Notes

Select this component when a 36 V Zener voltage with ±2% tolerance is required for precision applications. Consider the 5 W power dissipation capability and T-18 axial package constraints during PCB layout. Evaluate thermal management requirements based on the junction-to-lead thermal resistance specification. Compare against other suffix options (A, B, D) if different voltage tolerances or surge current ratings better suit the specific circuit demands.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 V to 200 V. The 'C' suffix specifically denotes a tighter ±2% voltage tolerance compared to standard B (±5%) or A (±10%) variants. These components are JEDEC registered and designed for robust performance in demanding electronic environments.

Replacement Considerations

Direct substitutes within the same series include 1N5365B (±5% tolerance) or 1N5365D (±1% tolerance). Cross-manufacturer equivalents should be verified against the 5 W power rating, T-18 package dimensions, and specific electrical parameters such as dynamic impedance and leakage current.
