ZMM5256B-13

Single Zener Diodes Overview

The ZMM5256B-13 is a single silicon Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 30 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device utilizes a DO-213AA (Mini-MELF) glass package for surface-mount installation. Key electrical characteristics include a maximum dynamic impedance of 49 Ohms and a reverse leakage current of 100 nA at 23 V. The forward voltage is specified as 1.1 V at 200 mA. It operates within a junction temperature range of -65°C to 175°C.

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized channels, as this part number may be discontinued or subject to obsolescence notices. Confirm RoHS compliance status and specific manufacturing lot details against the latest official datasheet revision. Ensure the supplier provides traceable documentation matching the Vishay General Semiconductor - Diodes Division specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 30 V Zener voltage with tight ±5% tolerance is required in a compact surface-mount form factor. The Mini-MELF package offers thermal performance suitable for 500 mW dissipation. Consider the 49 Ohm dynamic impedance for regulation precision requirements. Verify that the operating environment stays within the specified -65°C to 175°C junction temperature limits.

Single Zener Diodes Part Context

This component belongs to the ZMM52 series of standard Zener diodes from Vishay. The series covers a wide voltage range using the same Mini-MELF glass case structure. The 'B' suffix indicates the ±5% voltage tolerance variant. This family is designed for general-purpose voltage regulation and protection tasks where space constraints favor surface-mount technology over axial leaded packages.

Single Zener Diodes Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 1N5256B series from other manufacturers. Verify pinout compatibility and exact voltage tolerance matches when cross-referencing with alternative suppliers. Check for any changes in package dimensions or thermal resistance if substituting with non-Vishay equivalents.
