1N4751AP-AP

Overview

The 1N4751AP-AP is a hermetically sealed glass Zener diode manufactured by Micro Commercial Components. It provides voltage regulation with a nominal Zener voltage of 30V and a tolerance of ±5%. The device features a maximum power dissipation of 1W and operates in the DO-41G package. Key electrical parameters include a maximum reverse leakage current of 5µA at 22.8V, a maximum dynamic impedance of 40Ω, and a forward voltage of 1.2V at 200mA. It supports through-hole mounting and complies with RoHS standards.

Feature Summary

• Hermetic glass encapsulation for environmental protection
• Voltage regulation across broad operating ranges
• JEDEC registered standard compliance

Applications

• General purpose voltage regulation
• Protection circuits requiring hermetic sealing

Procurement Notes

Verify the specific suffix 'AP' against official MCC documentation to confirm hermetic sealing status and lead-free compliance. Ensure the DO-41G package dimensions match the target PCB layout. Cross-reference datasheets from authorized distributors to validate the exact manufacturing lot specifications and RoHS certification status before procurement.

Selection Notes

Select this component when hermetic sealing is required for the 30V Zener application. The DO-41G glass package offers superior moisture resistance compared to plastic alternatives. Verify that the 1W power rating and 40Ω impedance meet the circuit's thermal and noise requirements. Confirm availability of the specific AP suffix variant as it denotes distinct packaging characteristics.

Part Context

This part belongs to the 1N47xx series of 1-watt Zener diodes produced by Micro Commercial Components. The series covers a wide voltage range from 3.3V to 75V. The 1N4751AP-AP specifically utilizes a glass passivated junction within a hermetic DO-41G package, distinguishing it from standard plastic encapsulated versions like the 1N4751A.

Replacement Considerations
