1N5248B-G

Single Zener Diodes Overview

The Comchip Technology 1N5248B-G is a silicon unidirectional voltage regulator diode designed for through-hole mounting. It features a nominal Zener voltage of 18 V with a standard tolerance of ±5%. The component operates within a power dissipation rating of 0.5 W and utilizes the DO-35 glass axial leaded package. Key electrical characteristics include a maximum dynamic impedance of 30 Ω, a reverse leakage current of 100 nA at 14 V, and a forward voltage drop of 1.1 V at 200 mA. It supports an operating temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single silicon junction structure.
• Encased in hermetically sealed glass axial leads for environmental protection.
• Capable of handling high thermal loads up to 175 °C junction temperature.

Single Zener Diodes Applications

• General purpose voltage reference circuits
• Overvoltage protection stages
• Clamping applications in signal processing

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required tolerance grade, as variations exist within the series. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation, as regulatory adherence can vary by production batch. Ensure the ordering quantity aligns with the minimum packaging requirements specified in the official datasheet to avoid fulfillment delays.

Single Zener Diodes Selection Notes

Select this component when a robust, low-power voltage reference is needed in a traditional axial leaded form factor. The 18 V rating suits applications requiring moderate regulation levels without excessive heat generation. Consider the 30 Ω impedance limit for noise-sensitive designs and verify that the 0.5 W power dissipation capacity meets the circuit's thermal budget under worst-case operating conditions.

Single Zener Diodes Part Context

This device belongs to the broader JEDEC registered 1N52xx series of Zener diodes, widely recognized for their reliability in commercial electronics. Comchip Technology manufactures this variant to meet standard industry specifications for voltage regulation. The DO-35 package remains a common choice for prototyping and legacy board designs requiring through-hole assembly techniques.

Single Zener Diodes Replacement Considerations

Equivalent parts include Vishay 1N5248B and Microchip 1N5248B, which share identical electrical ratings and pin configurations. Verify package dimensions and lead spacing compatibility before substitution to ensure proper fit on existing printed circuit boards.
