1N958B TR TIN/LEAD

Single Zener Diodes Overview

The 1N958B TR TIN/LEAD is a single Zener diode manufactured by Microchip Technology, distributed under the Central Semiconductor Corp brand. It features a nominal Zener voltage of 7.5 V with a 5% tolerance and operates in a DO-204AH-2 (DO-41) through-hole package. The device dissipates up to 500 mW at temperatures ranging from -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 75 uA, a Zener impedance of 5.5 Ohms, and a test current of 16.5 mA. It is supplied in a reel packaging format.

Single Zener Diodes Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is attributed to Microchip Technology in official specifications despite the brand context. Confirm the presence of the 'TR' suffix indicates reel packaging and ensure the tin/lead composition meets project material requirements before ordering.

Single Zener Diodes Selection Notes

Select this component when a precise 7.5 V reference is required in a standard axial through-hole form factor. Consider the 500 mW power dissipation limit and the 5.5 Ohm impedance for noise-sensitive applications. Ensure the operating environment stays within the specified -65°C to +175°C temperature range for reliable performance.

Single Zener Diodes Part Context

This component belongs to the standard Zener diode category, widely used for voltage clamping and regulation. The 1N958B designation aligns with historical industry standards for 7.5 V devices. Its availability in a reel format supports automated surface or through-hole assembly processes in high-volume manufacturing environments.

Single Zener Diodes Replacement Considerations

Consult official datasheets for cross-reference candidates such as other 7.5 V Zener diodes in the DO-41 package. Verify that any substitute matches the 500 mW power rating, 5% voltage tolerance, and thermal characteristics to ensure circuit compatibility.
