1N4750G

Overview

The Taiwan Semiconductor 1N4750G is a hermetically sealed glass passivated junction silicon Zener diode designed for voltage regulation and reference applications. It operates within a power dissipation of 1 W and features a wide Zener voltage range from 3.3 V to 56 V across the series, with this specific model providing a nominal 27 V. The device offers a standard tolerance selection of ±5% on the nominal Zener voltage. It utilizes a DO-41 through-hole package with pure tin plated leads that are solderable per J-STD-002 standards. The component supports a maximum junction temperature of 200 °C and includes built-in strain relief.

Feature Summary

• Hermetically sealed glass compression bonded construction ensures corrosion resistance and reliable performance in demanding environments.
• Built-in strain relief mechanism protects the internal die and enhances mechanical stability during thermal cycling.
• Pure tin plated leads provide excellent solderability compliant with J-STD-002 standards for robust PCB attachment.

Applications

• Low voltage stabilizers
• Voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Procurement Notes

Verify the exact ordering suffix (e.g., R0G or A0G) against your manufacturing requirements, as packing quantities vary by reel or ammo box configuration. Confirm RoHS compliance status and lead finish specifications directly with the manufacturer or authorized distributors prior to finalizing procurement orders to ensure alignment with current production standards.

Selection Notes

Select the 1N4750G when a precise 27 V regulation point is required within a 1 W power dissipation limit. Ensure the application environment remains within the specified -65 °C to +200 °C junction temperature range. Verify that the DO-41 through-hole footprint matches the target PCB layout constraints and that the ±5% voltage tolerance meets the circuit design accuracy requirements.

Part Context

This component belongs to the 1N4728G–1N4758G series manufactured by Taiwan Semiconductor Corporation. The series covers a broad spectrum of Zener voltages from 3.3 V up to 56 V, all sharing identical mechanical and thermal characteristics. Each part number corresponds to a specific nominal voltage value while maintaining consistent package dimensions and hermetic sealing properties throughout the lineup.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4750A variants, provided they match the 27 V nominal voltage, 1 W power rating, and DO-41 package form factor. Verify that any replacement maintains equivalent hermetic sealing and thermal resistance characteristics to ensure compatibility with existing board designs and environmental ratings.
