1N4746A,113

Overview

The Nexperia 1N4746A,113 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 18 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 test current of 14 mA, a differential resistance of 20 Ω, and a maximum reverse current of 5 µA.

Feature Summary

• Hermetically sealed small glass package for environmental protection
• ±5% tolerance series for precise voltage regulation
• Low forward voltage characteristic

Applications

• Low voltage stabilizers

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging format and compliance status. Confirm RoHS and REACH alignment with project requirements before procurement. Ensure the component matches the required hermetically sealed glass package specification for the intended application environment.

Selection Notes

Select this component when a stable 18 V reference is required in through-hole designs. The DO-41 package offers robust mechanical stability. Verify that the 1 W power dissipation rating meets the thermal management needs of the circuit under maximum ambient temperature conditions.

Part Context

This part belongs to the 1N47xxA series of voltage regulator diodes manufactured by Nexperia. The series covers nominal working voltages from 3.3 V to 24 V. All types share the same SOD66 (DO-41) axial leaded package and general feature set, differing primarily in their specific Zener voltage ratings.

Replacement Considerations

Direct replacements must match the 18 V Zener voltage, 1 W power rating, and DO-41 package. Verify compatibility with other manufacturers' 1N4746A equivalents regarding tolerance and thermal characteristics.
