1N5238B-TAP

Single Zener Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N5238B-TAP is a silicon planar power Zener diode housed in the DO-35 (DO-204AH) axial through-hole package. It provides a nominal Zener voltage of 8.7 V with a standard tolerance of ±5%. The device operates at a test current of 20 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 3 µA at 6.5 V, a typical dynamic resistance of 8 Ω, and a temperature coefficient of 0.065 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features a standard ±5% Zener voltage tolerance designated by the 'B' suffix
• Designed for high thermal stability with a junction temperature rating of 175 °C

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the TAP suffix to confirm the specific ammopack packaging format. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the document number 85588 for the most current technical specifications and revision history before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when an 8.7 V reference is required in a through-hole configuration. The ±5% tolerance suits general-purpose applications where tight precision is not critical. Consider the 500 mW power dissipation limit and ensure adequate heat sinking or lead length management to maintain safe operating temperatures during continuous operation.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of voltages from 2.4 V to 75 V. The 1N5238 variant specifically targets the lower end of the mid-voltage spectrum, offering stable performance in compact axial packages suitable for various electronic assemblies.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include 1N5238B-TR and 1N5238B-TDIODE. Other manufacturers may offer equivalents such as 1N759A, provided they match the 8.7 V nominal voltage, 500 mW power rating, and DO-35 package dimensions.
