MMSZ5258A-AU_R1_000A1

Single Zener Diodes Overview

The MMSZ5258A-AU_R1_000A1 is a surface mount silicon Zener diode manufactured by Panjit International Inc. It features a nominal Zener voltage of 36 V with a maximum power dissipation of 500 mW at 25°C ambient temperature. The device operates within a junction and storage temperature range of -55°C to +150°C. Key electrical characteristics include a maximum Zener impedance of 70 Ohms measured at a test current of 3.4 mA, and a maximum reverse leakage current of 100 nA at the rated voltage. It utilizes an SOD-123 package.

Single Zener Diodes Procurement Notes

Verify the specific suffix AU against official Panjit documentation to confirm AEC-Q101 qualification status, as this attribute is tied to the ordering code. Ensure the required packaging quantity matches the manufacturer's standard reel sizes of 3,000 or 10,000 units. Confirm that the SOD-123 footprint aligns with your PCB design guidelines before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 36 V reference voltage is required in space-constrained designs utilizing the SOD-123 form factor. The 500 mW power rating supports moderate current handling capabilities suitable for general-purpose regulation tasks. Consider the 70 Ohm impedance value for applications sensitive to dynamic voltage variations under changing load conditions.

Single Zener Diodes Part Context

This part belongs to the MMSZ52xxA-AU series of surface mount Zener diodes produced by Panjit. The series covers a wide voltage range from 4.3 V to 51 V, all sharing the same physical SOD-123 package dimensions and mechanical data. The AU suffix specifically denotes the automotive-grade variant that meets AEC-Q101 reliability requirements.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 36 V nominal voltage, 500 mW power rating, and SOD-123 package. Verify if the alternative component requires AEC-Q101 qualification; if so, ensure the substitute also carries this certification. Check for identical pinout polarity and thermal characteristics to maintain circuit integrity.
