1N5237B BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5237B BK TIN/LEAD is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 8.2 V with a tolerance of ±5%. The device operates in a through-hole DO-35-2 package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 3 µA, a Zener impedance of 8 Ohms, and a test current of 20 mA. It supports an operating temperature range from -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single silicon Zener junction
• Constructed with a glass axial-lead DO-35 package for through-hole mounting
• Capable of high-temperature operation up to +200 °C

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation, as this part number appears under Central Semiconductor Corp in some records while other variants exist under Microchip Technology or Vishay. Confirm the exact suffix 'BK TIN/LEAD' matches the required lead finish and packaging format. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process.

Single Zener Diodes Selection Notes

Select this component when a standard 8.2 V Zener voltage is required with moderate power handling capabilities. The DO-35 package is suitable for general-purpose PCB layouts where through-hole technology is preferred. Consider the 5% voltage tolerance and 8 Ohm impedance for circuit stability requirements.

Single Zener Diodes Part Context

This component belongs to the widely used 1N52xx series of 500 mW Zener diodes. These devices are standard industry components available from multiple manufacturers including Central Semiconductor, Microchip, and Vishay. The series covers a broad range of voltages from 2.4 V to higher values, providing a versatile solution for basic voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N5237B from Microchip Technology and Vishay General Semiconductor. Other equivalents may be found among Central Semiconductor's own product lines. Verify that any replacement maintains the same DO-35 package, 500 mW power rating, and 8.2 V nominal voltage.
