1N5367E3/TR13

Overview

The Microchip Technology 1N5367E3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 43V with a standard tolerance of ±5%. The device features an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 20 ohms, a maximum reverse current of 0.5 µA, and a maximum regulator current of 2.8A. The component is RoHS compliant and available in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile integration
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against transient overvoltage events
• Reference voltage generation in industrial control systems

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'e3' suffix indicates RoHS compliance, while the 'TR13' suffix specifies tape and reel packaging. Confirm the specific tolerance requirements align with the 'B' designation for ±5% accuracy. Ensure the procurement documentation references the correct JEDEC registration number for quality assurance purposes.

Selection Notes

Select this component when a 5-watt power dissipation rating is necessary for high-current applications. The wide selection of voltages from 3.3V to 200V allows for precise matching to circuit requirements. Consider the low thermal resistance design if operation at high maximum DC currents is expected. Verify that the axial-lead form factor fits the mechanical constraints of the target PCB layout.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally manufactured by Microsemi. The series is JEDEC registered and designed for plastic encapsulation. Surface mount equivalents are available in SMBJ and SMBG packages. The product line supports various military screening levels through specific prefix identifiers.

Replacement Considerations

Surface mount equivalents such as SMBJ5367B or SMBG5367B are available from the same manufacturer family.
