1N5248/TR

Single Zener Diodes Overview

The Microchip Technology 1N5248/TR is a single Zener diode designed for voltage regulation applications. It features an 18 V nominal Zener voltage with a 5% tolerance and operates within a temperature range of -65°C to +175°C. The device dissipates up to 500 mW in a DO-204AH-2 (DO-35) through-hole package. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 21 Ohms at a test current of 7 mA, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with tight 5% tolerance across a wide industrial temperature range.
• Engineered for high thermal stability with a maximum operating temperature of +175°C.
• Offers low leakage current characteristics suitable for precision circuit protection.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications in signal conditioning paths.

Single Zener Diodes Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm packaging configuration. The /TR designation typically indicates reel packaging, which differs from bulk options. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when an 18 V regulation point is required in a standard axial leaded package. Ensure the circuit design accommodates the 500 mW power dissipation limit and the 21 Ohm dynamic impedance. Verify that the 100 nA leakage current meets the requirements of the specific application environment.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of glass-passivated Zener diodes manufactured by Microchip Technology. These components are widely used in general-purpose electronics for their reliability and standardized DO-35 form factor. The series covers a broad range of voltage values to support diverse voltage regulation needs.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5248 equivalents in DO-35 packages. Verify that substitute parts match the 18 V Zener voltage, 500 mW power rating, and 5% tolerance specifications to ensure functional compatibility.
