1N5247BTR

Single Zener Diodes Overview

The onsemi 1N5247BTR is a single silicon Zener diode housed in an axial leaded DO-35 (Case 017AG) glass package. It provides a nominal Zener voltage of 17 V with a tolerance range of 16.15 V to 17.85 V at a test current of 7.4 mA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +200°C. Key electrical characteristics include a dynamic impedance of 19 Ohms, a reverse leakage current of 100 nA at 13 V, and a positive temperature coefficient of 0.084 %/°C.

Single Zener Diodes Feature Summary

• Utilizes hermetically sealed glass construction for environmental stability

• Designed for through-hole mounting via axial leads

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'TR' corresponds to tape and reel packaging rather than bulk bags when sourcing. Confirm that the component meets RoHS and halide-free requirements as specified in the manufacturer's documentation. Ensure compatibility with automated placement equipment if utilizing the reel format.

Single Zener Diodes Selection Notes

Select this component for applications requiring a precise 17 V reference point with low leakage characteristics. The high operating temperature capability up to 200°C allows for use in thermally demanding environments. Consider the 5% voltage tolerance and 19 Ohm dynamic impedance when designing precision regulation networks.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of Zener diodes manufactured by onsemi. The series covers a wide voltage range from 2.2 V to 24 V, all sharing similar physical dimensions and thermal ratings. The 1N5247B variant specifically targets the 17 V segment of this standardized product line.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering JEDEC DO-35 packaged Zener diodes rated at 17 V with comparable power dissipation and tolerance specifications.
