1N5365C/TR8

Overview

The Microchip Technology 1N5365C/TR8 is a silicon unidirectional Zener voltage regulator diode belonging to the JEDEC registered 1N5333-5388B series. It provides a nominal Zener voltage of 36 V with a tight tolerance of ±2%, indicated by the C suffix. The device operates in a T-18 axial leaded package and dissipates up to 5.0 watts at 25°C ambient temperature. Electrical characteristics include a maximum dynamic impedance of 11 Ohms, a maximum reverse leakage current of 0.5 µA, and a maximum regulator current of 3.3 A.

Feature Summary

• Provides precise voltage regulation within a wide selection range from 3.3 to 200 volts.
• Features flexible axial-lead mounting terminals suitable for through-hole applications.
• Withstands high surge stresses and exhibits minimal changes in voltage versus current.
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020.

Applications

• Voltage regulation over broad operating current and temperature ranges
• High specified maximum current applications requiring adequate heat sinking
• General purpose voltage reference circuits

Procurement Notes

Verify component authenticity against official Microchip or Microsemi datasheets due to historical manufacturing transitions. Confirm that the TR8 suffix indicates tape and reel packaging compliant with EIA-296 standards. Ensure the specific C suffix matches the required ±2% voltage tolerance for your design specifications before procurement.

Selection Notes

Select this component when a precise 36 V regulation point is required with tighter tolerances than standard B or A suffix devices offer. The T-18 package supports high power dissipation of 5 watts, making it suitable for applications needing robust thermal performance. Verify that the circuit design accommodates the maximum regulator current of 3.3 A under appropriate heat sinking conditions.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally developed by Microsemi's Scottsdale Division. The series is JEDEC registered and offers various voltage options with different tolerance suffixes. The 1N5365C variant specifically targets applications demanding higher precision compared to the standard ±5% B suffix devices.
