MAT01GHZ

Overview

The MAT01GHZ is a matched monolithic dual NPN transistor manufactured by Analog Devices Inc. It utilizes an exclusive silicon nitride triple passivation process to ensure stability of critical parameters over temperature and time. The device features a maximum offset voltage (VOS) of 0.5 mV at 25°C, with a minimum current gain (hFE) of 250 at IC = 10 µA. It operates within a collector-emitter breakdown voltage (BVCEO) of 45 V and supports a total power dissipation of 1.8 W at case temperatures up to 40°C. The component is housed in a 6-pin metal header package (H-06) and functions reliably across an operating temperature range of -55°C to +125°C.

Feature Summary

• Monolithic dual NPN configuration with silicon nitride triple passivation for enhanced parameter stability

• High current gain maintained across a wide six-decade collector current range
• Ultra-low low-frequency noise voltage density

Applications

• Precision weigh scales
• Low noise operational amplifier front ends
• Current mirror and sink/source circuits
• Low noise instrumentation amplifiers
• Logarithmic amplifiers

Procurement Notes

Verify the specific ordering suffix Z indicates RoHS compliance status as defined in the official Analog Devices ordering guide. Confirm that the H-06 package option matches the required mechanical footprint for the target assembly. Ensure procurement channels provide documentation verifying the component origin directly from Analog Devices or authorized distributors to prevent counterfeit parts.

Selection Notes

Select the MAT01GHZ when a maximum offset voltage of 0.5 mV is acceptable compared to the tighter 0.1 mV limit of the AH variant. Consider the high hFE linearity from 10 nA to 10 mA for applications requiring consistent gain over varying signal levels. Evaluate the 45 V breakdown voltage against circuit supply rails to ensure adequate safety margins during transient conditions.

Part Context

The MAT01 series represents a family of matched monolithic transistors designed for precision analog applications. The GHZ variant specifically offers relaxed offset voltage specifications compared to the AHZ model while maintaining identical package dimensions and thermal characteristics. This allows designers to optimize cost without sacrificing the fundamental matching benefits provided by the monolithic construction process.

Replacement Considerations

Direct pin-compatible replacements within the same family include the MAT01GH. Designers must verify if the non-Z suffix meets environmental compliance requirements for their specific application before substituting.
