1N4735A

Overview

The onsemi 1N4735A is a single-channel general-purpose Zener diode housed in a DO-41 through-hole package. It features a nominal Zener voltage of 6.2 V with a tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range of -65°C to +200°C. Key electrical parameters include a test current of 41 mA, a maximum Zener impedance of 2 Ω, and a maximum reverse leakage current of 10 μA.

Feature Summary

• Provides stable voltage regulation at a nominal 6.2 V level for circuit protection and reference applications.
• Utilizes a robust DO-41 axial leaded glass package designed for reliable through-hole mounting.
• Capable of handling high thermal loads with a maximum power dissipation rating of 1 W.

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the specific ordering suffix (e.g., ATR, T50A) against the required packaging format, as these indicate distinct shipping configurations such as Ammo Pack or Tape & Reel. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Ensure the selected variant matches the required voltage tolerance and thermal performance specifications for the target application environment.

Selection Notes

Select this component when a standard 6.2 V reference is required in a through-hole design. The DO-41 package offers mechanical stability for manual or automated insertion processes. Consider the 1 W power rating for thermal management requirements and verify that the 2 Ω dynamic impedance meets the noise and regulation sensitivity needs of the specific circuit topology.

Part Context

This part belongs to the widely recognized 1N47 series of 1-watt Zener diodes. The 'A' suffix typically denotes a 5% voltage tolerance, distinguishing it from tighter tolerance variants like the 'C' or 'D' grades. The series provides a broad selection of voltage values within the same standardized physical footprint, facilitating inventory simplification across various industrial and consumer electronics designs.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4735A designation in the DO-41 package. Verify that substitute parts maintain the 6.2 V nominal voltage, 1 W power rating, and compatible pinout dimensions to ensure direct interchangeability without PCB layout modifications.
