1N5248B TR TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5248B TR TIN/LEAD is a single silicon Zener diode designed for voltage regulation applications. It features an 18 V nominal Zener voltage with a 5% tolerance and operates within a power dissipation rating of 500 mW. The device utilizes a DO-35 axial leaded package suitable for through-hole mounting, supporting a wide operating temperature range from -65 °C to +200 °C. Key electrical characteristics include a maximum reverse leakage current of 3 µA, a Zener impedance of 10 Ω at a test current of 20 mA, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon junction structure.
• Engineered for high thermal stability with an extended maximum operating temperature of +200 °C.
• Constructed in a hermetically sealed glass axial package to ensure environmental durability.

Single Zener Diodes Applications

• Precision voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications in signal processing paths.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to confirm lead material composition and reel packaging specifications. Ensure that the requested part number matches the exact electrical tolerances and thermal ratings required by the design. Cross-reference the manufacturer's latest datasheet to validate compliance with current environmental directives and RoHS status before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a robust 18 V regulation point is needed in a standard axial package. The high maximum junction temperature rating allows for operation in thermally demanding environments where standard commercial grade parts may fail. Consider the low leakage current specification for applications requiring minimal standby power consumption or high-impedance circuit interfaces.

Single Zener Diodes Part Context

This component belongs to the widely recognized 1N52xx series of 500 mW Zener diodes. This family offers a broad spectrum of voltage options within a consistent physical footprint and power handling capability. The 1N5248B variant specifically addresses the need for an 18 V regulation point within this established industrial standard lineup.

Single Zener Diodes Replacement Considerations

Direct replacements include the 1N5248B PBFREE variant from Central Semiconductor and equivalent 18 V Zener diodes from other manufacturers such as onsemi or Microchip Technology, provided they match the DO-35 package and 500 mW power rating.
