1N3780

Single Zener Diodes Overview

The 1N3780 is a temperature-compensated Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.7 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 400 mW and has a maximum dynamic impedance of 10 Ohms. It is housed in a DO-7 through-hole package, suitable for general-purpose voltage reference and regulation applications requiring stable performance across varying temperatures.

Single Zener Diodes Procurement Notes

Verify the manufacturer origin as Microchip Technology when sourcing. Confirm the package type is DO-7 and the Zener voltage is 6.7 V. Ensure the component status is active. Check for any specific ordering suffixes that may indicate packaging variations, though standard bulk availability is common. Cross-reference datasheets to confirm impedance and tolerance specifications match project requirements.

Single Zener Diodes Selection Notes

Select this component when a stable voltage reference near 6.7 V is required in low-power applications. The temperature compensation feature makes it suitable for environments where voltage drift must be minimized. Compare against other 1N37xx series variants if different voltage levels are needed. Ensure the 400 mW power rating suffices for the expected current draw in the circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N37xx series of temperature-compensated Zener diodes produced by Microchip Technology. These components are designed to provide stable voltage references over a wide temperature range. The series includes various voltage options, with the 1N3780 specifically offering 6.7 V. It is commonly used in analog circuits requiring reliable regulation without complex feedback loops.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N3780 equivalents meeting the same electrical specifications. Verify pinout compatibility with the DO-7 package. Ensure replacement parts maintain the 6.7 V nominal voltage and ±5% tolerance. Temperature coefficient characteristics should be compared if precise thermal stability is critical.
