1N4751A-T

Overview

The 1N4751A-T is a single silicon Zener diode manufactured by Vishay General Semiconductor. It features a nominal Zener voltage of 30 V with a standard tolerance of ±5%. The device is designed for through-hole mounting in the DO-41 (DO-204AL) plastic package. It supports a maximum power dissipation of 1.3 W and operates within a temperature range of -65 °C to +175 °C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 40 Ohms at a test current of 8.5 mA.

Feature Summary

• Glass passivated die construction for enhanced stability
• Low inductance design suitable for high-frequency applications
• Plastic case material with UL flammability classification rating 94V-0

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources

Procurement Notes

Verify component authenticity against official Vishay datasheets. Confirm package type matches DO-41 requirements. Check RoHS compliance status as manufacturing specifications may vary by production batch. Ensure storage conditions align with humidity sensitivity level ratings provided in the technical documentation.

Selection Notes

Select this component when a 30 V reference is required in a through-hole configuration. The 1.3 W power rating allows for higher thermal handling compared to standard 1 W variants. Verify that the ±5% tolerance meets circuit precision requirements. Consider the operating temperature range limits for extreme environment deployments.

Part Context

This part belongs to the 1N47xx series of axial leaded Zener diodes. It shares functional similarities with other Vishay diodes in the same voltage class but differs in power handling capabilities. The DO-41 package provides mechanical robustness for general-purpose electronic assemblies requiring reliable voltage clamping.
