1N4758APE3/TR12

Overview

The Microchip Technology 1N4758APE3/TR12 is a silicon 1-watt Zener diode with a nominal voltage of 56 V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C and features a DO-41 axial lead package. The device exhibits a maximum dynamic impedance of 110 Ohms at a test current of 4.5 mA, with a reverse leakage current of 5 µA at 42.6 V. It includes RoHS compliance via the e3 suffix and tape-and-reel packaging indicated by TR12.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Constructed with void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation in power supply circuits
• Reference voltage generation in electronic systems
• Overvoltage protection components

Procurement Notes

Verify component authenticity against official Microchip datasheets. Confirm RoHS compliance status and tape-and-reel specifications match project requirements. Ensure handling procedures align with Level 1 moisture classification standards.

Selection Notes

Select this component for applications requiring precise 56 V regulation with standard 5% tolerance. Consider thermal derating curves when designing for high ambient temperatures or limited airflow conditions.

Part Context

This part belongs to the 1N4728AP through 1N4764AP series of plastic encapsulated Zener diodes. The 'e3' suffix denotes RoHS compliant tin plating, while 'TR12' specifies tape-and-reel packaging configuration.

Replacement Considerations

Consult manufacturer documentation for direct substitutes. Surface mount equivalents such as SMAJ4758A are available from the same product family.
