1N5070

Single Zener Diodes Overview

The Microchip Technology 1N5070 is a fused-in-glass, metallurgically bonded 3-watt Zener diode. It features a nominal Zener voltage of 14 V with a tolerance of ±5%. The device has a maximum impedance of 6 Ohms and offers a surge rating ten times greater than conventional 1-watt types. Packaged in an axial leaded format, it is designed for robust voltage regulation applications requiring high reliability and compact board space utilization.

Single Zener Diodes Procurement Notes

Verify the manufacturer designation carefully, as the 1N5070 part number is produced by multiple entities including Microchip Technology (formerly Microsemi) and Digitron Semiconductors. Confirm that the specific datasheet aligns with your required electrical tolerances and package dimensions before procurement to ensure compatibility with existing designs.

Single Zener Diodes Selection Notes

Select this component when a 14 V Zener reference is required with higher power handling than standard 1-watt diodes. The 3-watt rating allows for better thermal performance in continuous operation. Ensure the axial package fits the available PCB real estate, as the compact form factor is a key selection driver for space-constrained designs.

Single Zener Diodes Part Context

This component belongs to the 1N507x series of 3-watt glass Zener diodes. The series provides a range of voltage options from approximately 12 V to 200 V within the same physical package. This standardization simplifies inventory management while allowing designers to scale voltage requirements without changing the footprint or mounting style.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5070 equivalents such as those from Digitron Semiconductors. Verify that substitute parts maintain the 14 V nominal voltage, ±5% tolerance, and 3 W power dissipation ratings to ensure functional equivalence in the circuit.
