3.0SMBZ150A

Single Zener Diodes Overview

The Good-Ark Semiconductor 3.0SMBZ150A is a surface mount Zener diode housed in the DO-214AA (SMB) package. It features a nominal Zener voltage of 150V with a standard tolerance of ±5%. The device supports a maximum steady-state power dissipation of 3.0W at a lead temperature of 75°C and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a test current of 600mA, a maximum reverse leakage current of 1µA at 114V, and a dynamic impedance of 2.5Ω measured at the test current.

Single Zener Diodes Procurement Notes

Verify the specific part number suffix against official documentation to confirm exact marking codes and packaging configurations. Ensure compatibility with recommended pad layouts for the DO-214AA package during PCB design. Confirm thermal derating requirements are met for the intended operating environment to maintain the specified 3.0W power dissipation capability.

Single Zener Diodes Selection Notes

Select this component when a 150V reference or regulation point is required in a compact surface mount form factor. Consider the 3.0W power handling capacity relative to ambient temperature conditions and available heat sinking. Verify that the ±5% voltage tolerance aligns with circuit precision requirements and that the SMB package dimensions fit the mechanical constraints of the assembly.

Single Zener Diodes Part Context

This component belongs to the 3.0SMBZxxA series of surface mount Zener diodes manufactured by Good-Ark Semiconductor. The series covers a Zener voltage range from 10V to 200V, all sharing the same 3.0W power dissipation rating and DO-214AA (SMB) package style. This specific model represents the higher end of the voltage spectrum within this standardized product line.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 3.0W Zener diodes in the DO-214AA package with a 150V nominal voltage. Ensure equivalent specifications for Zener impedance, leakage current, and thermal resistance are met before substitution.
