1N4750A

Overview

The Lumimax Optoelectronic Technology 1N4750A is a 27V Zener diode with ±5% voltage tolerance and 1W power dissipation. It features a JEDEC DO-41 glass package, 35 Ohms maximum impedance, and 5 µA reverse leakage current at 20.6V. The device operates within a junction temperature range up to 200°C and supports high-temperature soldering at 260°C for 10 seconds.

Feature Summary

• Glass passivated junction construction
• Low Zener impedance characteristics
• High temperature soldering capability

Applications

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

Procurement Notes

Verify the manufacturer designation as Lumimax Optoelectronic Technology against standard industry listings. Confirm the specific package type matches the datasheet description of a glass body rather than plastic variants found in other series. Ensure compliance with the stated electrical limits before integration.

Selection Notes

Select this component for applications requiring a 27V reference with moderate precision. The DO-41 glass package offers thermal stability suitable for through-hole mounting. Consider the 35 Ohm impedance limit when designing for dynamic load variations.

Part Context

This part belongs to the 1N47xxA series of 1-watt Zener diodes. The series covers voltages from 3.3V to 75V. The 'A' suffix denotes a standard ±5% tolerance level. The device utilizes a glass-passivated junction for reliability.

Replacement Considerations

Standard equivalents include the generic 1N4750A specification. Verify pinout compatibility and thermal resistance values when substituting with parts from other manufacturers.
