1N5248B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5248B-1/TR is a single silicon planar Zener diode with an 18 V nominal voltage and ±5% tolerance. It features a maximum power dissipation of 500 mW and operates within a temperature range of -65 °C to +200 °C. The component utilizes a DO-35 (DO-204AH) through-hole package and includes a tape-and-reel suffix for automated assembly.

Single Zener Diodes Feature Summary

• Hermetically sealed construction for high reliability
• Voltage regulation across broad operating current and temperature ranges
• Standardized B-suffix tolerance specification

Single Zener Diodes Applications

• High-reliability voltage reference circuits
• Overvoltage protection in aerospace systems
• Precision analog signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific datasheet revision for the -1 suffix, as it denotes military-grade specifications distinct from commercial variants. Confirm RoHS compliance status, noting that leaded versions may be available for heritage applications. Ensure the TR suffix matches the required reel quantity for production integration.

Single Zener Diodes Selection Notes

Select this component when strict voltage stability and wide thermal endurance are required. The 18 V rating suits mid-range reference needs. Verify that the 500 mW dissipation capability aligns with the circuit's thermal design constraints and that the through-hole package fits the target PCB layout.

Single Zener Diodes Part Context

This part belongs to the 1N52xxB series of hermetically sealed Zener diodes manufactured by Microchip Technology. The series is characterized by its robust glass-passivated junction and suitability for demanding environments where standard commercial components would fail due to thermal or radiation stress.

Single Zener Diodes Replacement Considerations

Cross-reference with 1N5248B from other manufacturers like Vishay or ON Semiconductor for equivalent electrical performance. Verify pinout compatibility and ensure the replacement meets the same hermetic sealing requirements if used in critical applications.
