1N4751AHB0G

Overview

The Taiwan Semiconductor 1N4751AHB0G is a single silicon Zener diode designed for through-hole mounting in the DO-204AL (DO-41) package. It features a nominal Zener voltage of 30 V with a tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range of -55 °C to +150 °C. Key electrical parameters include a test current of 8.5 mA, a maximum reverse leakage current of 5 µA, and a Zener impedance of 40 Ohms.

Feature Summary

• Provides stable voltage regulation at a nominal 30 V level
• Constructed from silicon material for reliable unidirectional operation
• Designed for high-power dissipation up to 1 Watt
• Utilizes a standard axial leaded package for easy circuit integration

Applications

• General-purpose voltage reference circuits
• Overvoltage protection stages
• Power supply output regulation

Procurement Notes

Verify RoHS compliance status and REACH SVHC declarations directly with the manufacturer or authorized distributors before procurement. Confirm that the specific ordering suffix matches the required packaging configuration. Ensure the component meets all environmental operating limits defined in the official datasheet for the intended application environment.

Selection Notes

Select this component when a precise 30 V reference is required in a through-hole design. The DO-41 package offers robust mechanical stability for industrial environments. Consider the 5% voltage tolerance and 40 Ohm impedance characteristics to ensure compatibility with downstream circuit sensitivity requirements.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Taiwan Semiconductor Corporation. It is a standardized component widely used in electronic assemblies requiring basic voltage clamping or regulation functions. The HB0G suffix typically denotes specific manufacturing or packaging attributes defined by the producer.

Replacement Considerations

Equivalent parts include the generic 1N4751A specification. Verify pinout compatibility and thermal performance when substituting with components from other manufacturers such as Microsemi or Vishay.
