1N3051B-1

Single Zener Diodes Overview

The Microchip Technology 1N3051B-1 is a single Zener diode designed for through-hole mounting in the DO-204AL (DO-41) axial package. It features a nominal Zener voltage of 200 V with a tolerance of ±5% and a maximum power dissipation of 1 W. The device exhibits a maximum Zener impedance of 1500 Ohms at the test current, with a reverse leakage current of 2 µA measured at 152 V. The forward voltage drop is specified as 1.2 V at 200 mA. It operates reliably within an extended temperature range from -55°C to +175°C.

Single Zener Diodes Procurement Notes

Verify compliance requirements before procurement, as this component does not meet RoHS standards. Confirm that the specific military-grade suffix aligns with project qualification needs. Ensure the DO-204AL axial lead form factor fits the target PCB layout constraints. Validate thermal management strategies to maintain junction temperatures within the specified operational limits during continuous use.

Single Zener Diodes Selection Notes

Select this component when a precise 200 V regulation point is required with high reliability. The ±5% tolerance ensures consistent performance in critical applications. Consider the 1500 Ohm impedance characteristic for noise-sensitive designs. Verify that the 1 W power rating accommodates the expected load conditions without exceeding thermal boundaries.

Single Zener Diodes Part Context

This part belongs to the 1N3051 series of high-power Zener diodes manufactured by Microchip Technology. It serves as a robust voltage reference solution for industrial and aerospace environments. The DO-41 package provides mechanical stability for through-hole assembly processes. It is distinct from lower-power variants in the same family due to its higher wattage capability.
