1N5245BTR

Single Zener Diodes Overview

The onsemi 1N5245BTR is a single-channel general-purpose Zener diode housed in an axial lead DO-35 package. It provides a nominal Zener voltage of 15 V with a 5% tolerance, tested at 8.5 mA. The device dissipates up to 500 mW and maintains operation between -65°C and +200°C. Key electrical characteristics include a maximum dynamic impedance of 16 Ω, a reverse leakage current of 100 nA, and a positive temperature coefficient of 0.082 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation through precise Zener breakdown characteristics
• Features low reverse leakage current for efficient standby performance
• Utilizes a hermetically sealed glass axial lead package for robust environmental protection

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage clamping applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. Confirm that the component meets all required RoHS and REACH compliance standards for your target market. Ensure the selected variant matches the exact voltage and power dissipation requirements of the design before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 15 V reference point is required within standard operating temperatures. Evaluate the thermal environment to ensure the 500 mW power dissipation limit is not exceeded. Consider the positive temperature coefficient when designing circuits sensitive to ambient temperature fluctuations.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of Zener diodes manufactured by onsemi. The series utilizes a standardized DO-35 glass axial lead package. The 'B' designation indicates a 5% voltage tolerance, while the 'TR' suffix specifies tape and reel shipping.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5245B variants or equivalent 15 V Zener diodes in the DO-35 package. Verify that replacement parts match the 16 Ω dynamic impedance and 500 mW power rating to maintain circuit integrity.
