1N5368AE3/TR13

Overview

The Microchip Technology 1N5368AE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 47 V with a ±10% tolerance, indicated by the 'A' suffix. The device features an axial T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 25 Ohms and a maximum reverse leakage current of 0.5 µA tested at 33.8 V.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in industrial equipment

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via the e3 suffix designation. Ensure storage conditions adhere to Level 1 moisture sensitivity classification without requiring dry pack handling. Validate that the TR suffix corresponds to tape and reel packaging specifications per EIA-296 standards before procurement.

Selection Notes

Select this component for applications requiring a 47 V Zener reference with ±10% tolerance. Consider the 5-watt power rating and thermal resistance when designing heat sinking solutions. Verify compatibility with axial lead mounting requirements on FR4 printed circuit boards. Evaluate the maximum steady-state power dissipation limits based on ambient temperature conditions.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi Scottsdale Division. The series covers a wide voltage selection from 3.3 V to 200 V. The specific model utilizes the A suffix for standard voltage tolerances and the e3 suffix for RoHS compliant terminal plating.

Replacement Considerations

Surface mount equivalents are available as SMBJ5368 or SMBG5368. Other manufacturers may offer direct replacements within the 1N5368 specification range. Verify pinout compatibility and thermal performance characteristics when substituting.
