Overview
The Microchip Technology 1N4749AP/TR8 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 24 V with a tolerance of ±5%. The device operates in an axial DO-41 package and dissipates up to 1 W of power. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 25 Ohms, and a test current of 10.5 mA. It supports a wide operating temperature range from -65 °C to +175 °C.
Feature Summary
- Provides stable voltage regulation at a nominal 24 V reference level
- Operates reliably across extended industrial temperature ranges up to 175 °C
- Encapsulated in a hermetically sealed glass axial package for durability
Applications
- Low voltage stabilizers
- Voltage reference circuits
- Overvoltage protection
Procurement Notes
Verify the specific suffix 'AP' against official datasheets to confirm the 5% tolerance variant, as standard 'P' variants may differ. Confirm RoHS compliance status, as some sources indicate non-compliance for this specific part number configuration. Ensure the reel packaging matches production requirements.
Selection Notes
Select this component when a precise 24 V regulation point is required with tight tolerance specifications. The high-temperature rating makes it suitable for demanding environments where standard commercial grade parts may fail. Compare leakage current limits against circuit sensitivity requirements before finalizing the design.
Part Context
This part belongs to the widely used 1N47xx series of 1-watt Zener diodes manufactured by Microchip Technology. These components are standard replacements for legacy designs requiring robust voltage regulation in through-hole assemblies. The series offers extensive voltage selection within the same physical footprint.
Replacement Considerations
Compatible substitutes include the 1N4749AG/TR and 1N4749A. Verify that replacement parts maintain the same 24 V nominal voltage and 5% tolerance to ensure circuit compatibility.
