1N4733A,133

Single Zener Diodes Overview

The Nexperia 1N4733A,133 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 5.1 V with a tolerance of ±5%. The device supports a maximum total power dissipation of 1000 mW and operates within a junction temperature range of -65 °C to +200 °C. Key electrical characteristics include a forward voltage of 1.2 V at 200 mA, a differential resistance of 7 Ω, and a reverse current of 10 µA.

Single Zener Diodes Feature Summary

• Hermetically sealed small glass package construction
• Low voltage stabilizer functionality
• ±5% voltage tolerance series

Single Zener Diodes Applications

• Low voltage stabilizers

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as Ammo Pack or Reel configurations. Confirm RoHS compliance status and REACH registration requirements for your region before finalizing procurement orders. Ensure the component matches the required axial leaded format for your assembly process.

Single Zener Diodes Selection Notes

Select this component when a stable 5.1 V reference is required in through-hole designs. The DO-41 package offers robust mechanical stability for standard PCB mounting. Consider the thermal resistance from junction to tie-point if operating near maximum power dissipation limits in enclosed environments.

Single Zener Diodes Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series covers nominal working voltages ranging from 3.3 V to 24 V. All devices in this family share the same SOD66 package outline and general structural specifications while differing in their specific Zener voltage ratings.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N4733A from onsemi and the 1N4733A-T50A from onsemi. These parts maintain equivalent electrical characteristics and package dimensions for direct replacement in existing designs.
