1N5246BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5246BUR-1/TR is a single Zener diode rated at 16 V nominal voltage with a 5% tolerance. It features a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to +175°C TJ. The device utilizes a DO-213AA (SMB) surface-mount package and has a test current of 7.8 mA. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 17 Ohms, and a voltage temperature coefficient of 0.083 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation in a compact surface-mount SMB package
• Operates reliably across an extended junction temperature range up to 175°C
• Maintains low reverse leakage current for efficient standby performance

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 16 V levels
• Overvoltage protection stages in industrial control systems

Single Zener Diodes Procurement Notes

Verify the specific suffix BUR-1/TR against official Microchip documentation to confirm the exact reel quantity and tape-and-reel specifications. Ensure the DO-213AA footprint matches your PCB design constraints. Cross-reference the thermal management requirements with the 500 mW dissipation rating under your specific ambient conditions.

Single Zener Diodes Selection Notes

Select this component when a 16 V Zener voltage is required in a surface-mount configuration. The 5% tolerance suits general regulation tasks. Consider the 175°C operating limit for high-temperature environments. Compare the 17 Ohm impedance against circuit sensitivity requirements. Verify compatibility with automated assembly processes using the TR packaging format.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes manufactured by Microchip Technology. It represents the surface-mount equivalent of through-hole variants, offering similar electrical performance in a smaller form factor. The series is widely used in general-purpose electronic designs requiring reliable voltage clamping or reference functions.

Single Zener Diodes Replacement Considerations

Consult Microchip's official substitution guide for parameter-equivalent alternatives. Verify that any substitute maintains the 16 V nominal voltage, 500 mW power rating, and DO-213AA package dimensions. Ensure the replacement meets the same -65°C to +175°C operating temperature range.
