1N4735G A0G

Overview

The 1N4735G A0G is a silicon planar power Zener diode manufactured by Taiwan Semiconductor Corporation. It operates within the 1N4728G to 1N4764G series, providing voltage regulation capabilities with a nominal Zener voltage of 6.2V and a maximum power dissipation of 1W at 25°C ambient temperature. The device utilizes a DO-41 glass axial leaded package (JEDEC DO-204AL) designed for through-hole mounting. Standard tolerance for this component is ±10%, though tighter tolerances are available upon request. The unit features a hermetically sealed glass construction with corrosion-resistant external surfaces and pure tin solderable terminals.

Feature Summary

• Hermetically sealed glass package construction ensuring environmental resistance
• Silicon planar technology optimized for high-power stabilizing and clipping circuits
• Through-hole mounting configuration compatible with standard DO-41 footprints
• Corrosion-resistant external surfaces with readily solderable pure tin terminals

Applications

• Voltage stabilization in power supply circuits
• Signal clipping applications requiring high power ratings
• General-purpose voltage reference implementations
• Over-voltage protection stages in electronic systems

Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level, as standard units typically carry a ±10% Zener voltage tolerance while other options require explicit request. Confirm compliance with RoHS directives if restricted substances are prohibited in the assembly process. Ensure the procurement documentation specifies the correct package variant, as the DO-41 glass case differs from plastic equivalents. Validate terminal finish specifications against soldering requirements before finalizing orders.

Selection Notes

Select this component when a robust, hermetically sealed axial leaded Zener diode is required for power dissipation up to 1W. The DO-41 glass package offers superior thermal stability compared to plastic variants for high-temperature environments. Consider the standard ±10% tolerance unless precise voltage regulation necessitates custom ordering. Verify that the circuit design accommodates the physical dimensions and lead spacing inherent to the DO-41 form factor for proper PCB integration.

Part Context

This part belongs to the extensive 1N4728G through 1N4764G series of 1-watt Zener diodes produced by Taiwan Semiconductor. The series covers a wide voltage range from 3.3V to 100V, utilizing standardized JEDEC DO-41 packages. These devices are engineered for general-purpose voltage regulation tasks where reliability and thermal performance are critical. The manufacturing process ensures consistent electrical characteristics across the series for predictable circuit behavior.

Replacement Considerations

Equivalent parts include the 1N4735A and 1N4735 from manufacturers such as Microsemi or Fairchild, provided they meet the 1W power rating and DO-41 package constraints. Verify that substitute components maintain the same hermetic sealing and terminal finish specifications to ensure compatibility with existing assembly processes.
