MAT01AH

Overview

The MAT01AH is a matched monolithic dual NPN transistor manufactured by Analog Devices Inc. It features an offset voltage (VOS) maximum of 0.1 mV at 25°C and operates within a temperature range of -55°C to +125°C. Key electrical parameters include a minimum current gain (hFE) of 500, a breakdown voltage (BVCEO) of 45 V, and a collector saturation voltage of 0.8 V at high currents. The device utilizes a 6-pin metal header package (H-06) with through-hole mounting.

Feature Summary

• Monolithic dual NPN transistor structure utilizing silicon nitride triple passivation for parameter stability
• Low offset voltage matching with minimal temperature drift characteristics
• High current gain maintained across a wide six-decade collector current range
• Low noise voltage performance suitable for precision input stages

Applications

• Weigh scales
• Low noise op amp front ends
• Current mirror and current sink/source circuits
• Low noise instrumentation amplifiers
• Log amplifiers

Procurement Notes

Verify the specific ordering suffix when sourcing components. The 'Z' suffix indicates RoHS compliance, whereas non-Z variants may not meet current environmental standards. Confirm package orientation and pinout compatibility during integration. Ensure supply chain sources provide valid manufacturer documentation to guarantee authenticity and traceability.

Selection Notes

Select the MAT01AH over the MAT01GH variant when strict offset voltage limits are required, as the AH version guarantees a maximum VOS of 0.1 mV compared to 0.5 mV for the GH series. Consider the thermal derating requirements if operating above 70°C ambient temperature without heat sinking. Evaluate the low-frequency noise specifications against application sensitivity thresholds.

Part Context

The MAT01AH belongs to the MAT01 family of matched monolithic dual transistors designed for high-precision analog applications. This family emphasizes tight matching between the two internal transistors to minimize errors in differential circuits. The component is distinct from general-purpose discrete transistors due to its specialized matching characteristics and low-noise profile.

Replacement Considerations

Direct functional substitutes within the same family include the MAT01GH, which offers identical packaging but relaxed offset voltage specifications. Cross-family replacements require careful evaluation of hFE linearity and noise density parameters to ensure circuit performance remains within acceptable limits.
