1N4751AE3/TR13

Overview

The Microchip Technology 1N4751AE3/TR13 is a single silicon Zener diode housed in the DO-204AL (DO-41) axial package. It features a nominal Zener voltage of 30 V with a tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range of -65 °C to +150 °C. Key electrical parameters include a maximum reverse leakage current of 5 µA at 22.8 V and a Zener impedance of 40 Ω. The component is RoHS compliant and supplied in a reel packaging format.

Feature Summary

• Provides stable voltage regulation with a nominal 30 V Zener breakdown point
• Constructed from silicon material for reliable unidirectional operation
• Designed for high-reliability applications with hermetic sealing options in related variants
• Supports wide operating temperatures ranging from -65 °C to +150 °C

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources

Procurement Notes

Verify the specific suffix TR13 indicates reel packaging when ordering. Confirm RoHS compliance status as required by project specifications. Ensure the DO-204AL axial lead form factor matches the PCB layout constraints. Cross-reference the manufacturer part number with official Microchip documentation to confirm availability and exact electrical tolerances before finalizing procurement.

Selection Notes

Select this component for applications requiring a precise 30 V reference with ±5% tolerance. The 1 W power rating suits moderate current regulation tasks. Consider the axial DO-41 package for through-hole mounting requirements. Evaluate the 40 Ω impedance and 5 µA leakage current against circuit sensitivity needs. Ensure the operating environment stays within the specified -65 °C to +150 °C thermal limits.

Part Context

This part belongs to the standard 1N47xx series of 1 W Zener diodes manufactured by Microchip Technology. The 'e3' suffix typically denotes lead-free composition, while 'TR13' specifies the tape and reel quantity. It serves as a fundamental discrete semiconductor component for basic analog signal conditioning and power supply stabilization tasks in industrial electronics.

Replacement Considerations

Compatible substitutes include the 1N4751A and 1N4751AP from various manufacturers. Verify that replacement parts maintain the same 30 V Zener voltage, 1 W power rating, and DO-41 package dimensions. Check for equivalent tolerance levels and thermal characteristics to ensure functional interchangeability without circuit modification.
