1N4101D/TR

Single Zener Diodes Overview

The Microchip Technology 1N4101D/TR is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides an 8.2 V nominal Zener voltage with a tight ±1% tolerance, indicated by the 'D' suffix. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse leakage current of 6.3 µA at 6.3 V. Electrical characteristics include a test current of 250 µA, dynamic impedance of 0.5 Ohms, and a positive temperature coefficient of +0.070 %/°C.

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the 'TR' suffix to confirm tape and reel packaging availability. Confirm the 'D' designation matches the required ±1% tolerance specification. Ensure compatibility with MIL-PRF-19500/435 qualification levels if operating in regulated sectors. Check for RoHS compliance status as commercial versions may differ from qualified grades.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its narrow ±1% tolerance band. The wide operating temperature range supports deployment in extreme thermal conditions. Consider the low dynamic impedance for stable performance under varying load currents. Verify that the axial lead format fits the mechanical constraints of the target printed circuit board layout.

Single Zener Diodes Part Context

This device belongs to the 1N4099 through 1N4135 series of 500 mW Zener diodes manufactured by Microchip Technology. The series offers a broad selection of voltages from 1.8 V to 100 V. The 1N4101 variant specifically targets the 8.2 V regulation point. The 'D' suffix denotes the tighter manufacturing tolerance compared to standard commercial equivalents.
