1N4753G

Overview

The Taiwan Semiconductor 1N4753G is a single silicon Zener diode housed in a DO-41 axial leaded package. It provides a nominal Zener voltage of 36 V with a tolerance of ±5%. The device operates at a maximum power dissipation of 1 W and features a test current of 7 mA. Electrical characteristics include a maximum dynamic impedance of 50 Ω and a leakage current of 5 µA at 27.4 V. The component supports a junction temperature range from -65 °C to +200 °C.

Feature Summary

• Hermetically sealed glass passivated junction for environmental stability
• Low profile molded plastic case with built-in strain relief
• High temperature soldering capability guaranteed at 260°C for 10 seconds
• Green compound packaging compliant with UL 94V-0 flammability standards

Applications

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

Procurement Notes

Verify the specific suffix (e.g., R0G, A0G) against the required packing format, as the base part number covers multiple reel and ammo box options. Confirm RoHS compliance status directly with the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when a standard 36 V reference point is required within a wide thermal operating envelope up to 200 °C. Ensure the circuit design accommodates the specified 7 mA test current and 50 Ω impedance limits to maintain accurate voltage regulation under expected load conditions.

Part Context

This device belongs to the 1N4728G through 1N4758G series manufactured by Taiwan Semiconductor. The series spans a Zener voltage range from 3.3 V to 56 V, all sharing identical mechanical dimensions and thermal ratings while varying only in electrical breakdown specifications.

Replacement Considerations

Cross-reference with other manufacturers' 1N4753A variants. Verify that substitute components match the 1 W power rating, DO-41 footprint, and ±5% voltage tolerance to ensure direct interchangeability without PCB layout modifications.
