1N4745A,113

Overview

The Nexperia 1N4745A,113 is a voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 16 V with a tolerance series 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 test current of 15.5 mA, a differential resistance of 16 Ω, and a maximum reverse current of 0.25 µA at 5 V. The forward voltage is specified as 1.2 V at a forward current of 200 mA.

Feature Summary

• Hermetically sealed small glass package for reliable operation
• Wide operating voltage range from 3.3 V to 24 V across the series
• Tight voltage tolerance series of ±5%
• High thermal stability with extended junction temperature limits

Applications

• Low voltage stabilizers

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel or cut tape configuration. Ensure the component meets RoHS compliance requirements relevant to your manufacturing region. Cross-reference the manufacturer part number with authorized distributor databases to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a stable 16 V reference is required in through-hole designs. The DO-41 package accommodates standard PCB layouts while offering robust mechanical protection. Consider the 1000 mW power rating and thermal resistance characteristics to ensure adequate heat dissipation under continuous load conditions without exceeding maximum junction temperatures.

Part Context

This component belongs to the 1N4728A to 1N4749A series of low voltage regulator diodes manufactured by Nexperia. The series utilizes a consistent SOD66 axial leaded glass package structure. All variants share identical physical dimensions and limiting values, differing primarily in their nominal Zener voltage specifications which span from 3.3 V up to 24 V.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4745A equivalents that match the 16 V Zener voltage, 1 W power rating, and DO-41 package footprint. Verify that replacement parts maintain equivalent differential resistance and reverse leakage current specifications to ensure circuit performance parity.
