1N5250BTR

Single Zener Diodes Overview

The onsemi 1N5250BTR is a single-channel Zener diode with a nominal voltage of 20V and a maximum power dissipation of 500 mW. It utilizes an axial lead DO-35 package for through-hole mounting. The device features a 5% voltage tolerance, a test current of 6.2 mA, and a maximum Zener impedance of 25 Ω at the test current. Maximum reverse leakage current is specified as 100 nA at 15V reverse bias. The component operates within a junction temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape and reel packaging rather than bulk bags when sourcing this specific part number. Confirm the manufacturer is Semiconductor Components Industries, LLC (dba onsemi) to ensure compliance with the provided datasheet specifications. Check for RoHS and halide-free status if required by assembly standards.

Single Zener Diodes Selection Notes

Select this component when a precise 20V regulation point is required with tight 5% tolerance. Ensure the application can accommodate the 500 mW power dissipation limit and derating requirements above 50°C. Verify that the axial lead form factor fits the available board space and mounting constraints compared to surface mount alternatives.

Single Zener Diodes Part Context

This device belongs to the 1N5221B through 1N5252B series of Zener diodes manufactured by onsemi. The series covers a broad range of voltage ratings from 2.2V to 24V, all sharing similar physical dimensions and electrical characteristics tailored for general-purpose regulation tasks in the DO-35 axial package.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5250B variants or equivalent 20V Zener diodes in the DO-35 package. Ensure replacement parts match the 500 mW power rating and 5% tolerance to maintain circuit performance.
