1N5246B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5246B/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring a nominal voltage of 16 V with ±5% tolerance (B suffix). It operates within a temperature range of -65°C to +175°C and includes a TR suffix for tape-and-reel packaging per EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance characteristics suitable for high-frequency applications
• Constructed with a hermetically sealed glass axial-lead DO-35 package

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required electrical tolerances and thermal ratings for your design. Confirm the presence of the TR suffix indicates tape-and-reel packaging rather than bulk supply. Ensure compliance with RoHS requirements if applicable to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a standard 16 V Zener voltage with tight 5% tolerance is required. The DO-35 package supports through-hole mounting, while surface mount equivalents are available in MELF style. Consider the maximum power dissipation limits and derating curves for thermal management.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 V to 200 V with various tolerance options identified by suffix letters such as A, B, C, or D.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package. Glass body axial-leaded DO-7 equivalents are also offered as alternatives.
