1N4614

Single Zener Diodes Overview

The Microchip Technology 1N4614 is a Zener voltage regulator diode designed for precision voltage reference and regulation applications. It features a nominal Zener voltage of 5.6 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW, making it suitable for low-power circuit protection and biasing tasks. It operates within an extended junction temperature range from -65°C to +175°C, ensuring reliability in demanding environments. The component utilizes a DO-35 axial through-hole package, providing robust mechanical stability for standard PCB mounting.

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., -1, E3) against the design requirements, as these indicate variations in packaging or compliance status. Confirm RoHS compliance if required by the manufacturing process. Check current availability status, as lead times may vary significantly for this component type. Ensure the selected variant matches the required tolerance and package style for the target assembly.

Single Zener Diodes Selection Notes

Select the 1N4614 when a 5.6 V reference point is needed with moderate power handling capabilities. Consider the ±5% tolerance for general-purpose regulation where tight precision is not critical. Evaluate the thermal environment to ensure the 500 mW rating remains sufficient under worst-case operating conditions. Compare against surface-mount alternatives if space constraints exist on the printed circuit board layout.

Single Zener Diodes Part Context

This component belongs to the standard 1N4614–1N4627 series of Zener diodes manufactured by Microchip Technology. These devices are widely used in industrial and commercial electronics for basic voltage regulation needs. The series offers a range of voltage values from approximately 2.4 V to 75 V, allowing designers to select appropriate references without custom specifications. The 1N4614 specifically fills the gap for 5.6 V applications in legacy and modern designs alike.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4614 equivalents that meet the same electrical specifications. Variants such as 1N4614B may offer tighter tolerances if higher precision is required. Surface-mount replacements like CDLL4614 provide pin-compatible functionality in different packages. Always verify that any replacement maintains the required power rating and temperature range.
