1N4924A

Overview

The Microchip Technology 1N4924A is a single Zener diode housed in a DO-35 (DO-204AH) through-hole package. It features a nominal Zener voltage of 19.2 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW. This component is classified as an over-the-counter temperature compensated Zener reference, designed to provide stable voltage regulation across varying thermal conditions.

Feature Summary

• Temperature compensated design for stable voltage reference performance
• Low noise characteristics suitable for precision applications
• Through-hole mounting via DO-35 axial leaded package

Applications

• Precision voltage reference circuits
• Temperature compensated regulator designs
• Low noise analog signal conditioning

Procurement Notes

Verify the specific suffix (e.g., /TR) against your bill of materials, as it may indicate tape-and-reel packaging or RoHS compliance status. Confirm that the non-RoHS designation aligns with your assembly requirements. Ensure the DO-35 package footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a stable 19.2 V reference is required with low noise and temperature compensation. The DO-35 package suits through-hole assembly processes. Consider the 500 mW power rating to ensure adequate thermal headroom in the target circuit environment compared to lower-power alternatives.

Part Context

This part belongs to Microchip's family of temperature compensated Zener diodes. These components are engineered to minimize voltage drift over temperature ranges, offering superior stability compared to standard Zener diodes. The 1N4924A specifically targets applications requiring a precise 19.2 V reference point with minimal noise interference.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic 1N4924 equivalents only if datasheet parameters match exactly.
