1N5992D/TR

Single Zener Diodes Overview

The Microchip Technology 1N5992D/TR is a 4.7 V Zener voltage regulator diode housed in a DO-35 axial-lead glass package. It features a nominal Zener voltage of 4.7 V at a test current of 50 mA, with a maximum reverse leakage current of 3.0 µA and a dynamic impedance of 1.5 Ohms. The device supports a maximum DC Zener current of 106 mA and operates within a temperature range of -65°C to +175°C. It has a power dissipation rating of 0.5 W at 25°C and includes a tape-and-reel packaging option indicated by the TR suffix.

Single Zener Diodes Procurement Notes

Verify the specific tolerance class associated with the 'D' suffix (1%) against project requirements. Confirm that the 'TR' suffix indicates tape-and-reel packaging rather than bulk quantities. Ensure compatibility with the specified DO-35 through-hole mounting style and lead configuration before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 4.7 V reference is required with tight voltage tolerance. Consider the low dynamic impedance for stability under varying load conditions. Evaluate the thermal resistance values if operation near the upper temperature limit is anticipated. Verify RoHS compliance status if environmental regulations apply to the end application.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5985 through 1N6031 series of 0.5 watt Zener voltage regulators. These devices are widely used as standard voltage references in commercial and industrial electronics. The series offers a wide selection of voltages from 2.4 to 200 volts with various tolerance options.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 4.7 V Zener diodes in the DO-35 package with similar power ratings and tolerances. Cross-reference with BZX55 series equivalents for European market compatibility. Ensure any substitute matches the 0.5 W power dissipation and -65°C to +175°C operating temperature range.

Single Zener Diodes FAQ

What does the 'D' suffix indicate in the part number?

The 'D' suffix denotes a voltage tolerance of 1% for the nominal Zener voltage.

Is this component available in surface mount packages?

Yes, the series is also available in surface mount DO-213AA packages, but the 'TR' suffix specifically refers to the tape-and-reel packaging format for the axial-lead version.
