1N5244B

Single Zener Diodes Overview

The onsemi 1N5244B is a single silicon Zener diode housed in an axial lead DO-35 package. It provides a nominal voltage of 14 V with a tolerance of ±5%. The device dissipates up to 500 mW and operates within a junction temperature range of -65°C to +200°C. Electrical characteristics include a maximum dynamic impedance of 15 Ohms at a test current of 9 mA, a reverse leakage current of 100 nA at 10 V, and a positive voltage temperature coefficient of 0.08%/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional Zener junction.
• Features a hermetically sealed glass axial lead package for reliable operation.
• Designed for high thermal stability across a wide operating temperature range.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging format, as bulk bags and tape-and-reel options exist. Ensure compliance with RoHS and REACH requirements by checking the manufacturer's environmental declarations. Confirm that the component meets all absolute maximum ratings for your specific application environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 14 V regulation point is required with tight tolerance limits. Consider the low reverse leakage current and moderate dynamic impedance for sensitive signal paths. Evaluate the thermal derating curve if ambient temperatures exceed standard conditions to ensure power dissipation remains within safe operational limits.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of 0.5 W Zener voltage regulators. The series offers a broad selection of voltages from 2.4 V to 24 V in standard 5% tolerances. These components are widely used in industrial and commercial electronics where reliable, low-cost voltage regulation is necessary.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5244B equivalents to verify pinout compatibility and electrical parameter matching. Ensure any substitute maintains the same DO-35 axial lead form factor and hermetic sealing specifications for direct board replacement.
