MAZ20750AG

Single Zener Diodes Overview

The Panasonic MAZ20750AG is a silicon planar Zener diode from the MAZ2000 series, designed for power supply stabilization. It utilizes a glass-sealed DO-41-A1 package and offers a total power dissipation of 1 W at 25°C. The nominal Zener voltage is 7.5 V with a tolerance range of 7.0 V to 7.45 V (Rank A). Key electrical characteristics include a reverse current of 10 µA maximum at 40 V, an operating resistance of 5 Ω, and a temperature coefficient of 3.8 mV/°C. The device supports a repetitive peak forward current of 400 mA and a junction temperature up to 200°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required Zener voltage rank and package style before ordering. Confirm that the application falls within standard general electronic equipment categories, as special applications require separate consultation. Ensure the latest product standards are obtained directly from Panasonic sales representatives prior to final design implementation.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage around 7.5 V is required in a through-hole DO-41 package. Consider the 1 W power rating and thermal derating curves for high ambient temperatures. Verify that the 5 Ω operating resistance and low terminal capacitance meet the circuit's dynamic performance requirements.

Single Zener Diodes Part Context

This component belongs to the Panasonic MAZ2000 Series, which covers a wide Zener voltage range from 5.1 V to 56.0 V. The series is characterized by its silicon planar structure and glass seal, offering robust performance for standard industrial and consumer electronics applications requiring reliable voltage regulation.

Single Zener Diodes Replacement Considerations

Cross-reference with other DO-41 packaged Zener diodes rated for 7.5 V and 1 W. Ensure equivalent or superior specifications for reverse current, operating resistance, and thermal dissipation capabilities are met during substitution.

Single Zener Diodes FAQ

What does the 'A' suffix indicate in the MAZ20750A designation?

The 'A' suffix denotes Rank A classification, indicating a tighter Zener voltage tolerance range of 7.0 V to 7.45 V compared to Rank B.

How is the Zener voltage rank visually identified on the component?

The voltage rank is indicated by colored bands on the component body; Rank A uses Purple, Green, and Green bands for the MAZ20750A variant.
