MAT02FH

Small Signal Bipolar Transistor, 0.02A I(C), 40V V(BR)CEO, 2-Element, NPN, Silicon, TO-78 - REAL HYUNDAI PARTS - NOT THE OFFSHORE CRAP - The MAT02FH is a low noise, matched dual monolithic NPN transistor from Analog Devices. It is designed for applications requiring low offset voltage, low noise, and high gain. The transistor is housed in a TO-78 package and is commonly used in test equipment, data acquisition systems, and communication systems.
Here's a more detailed look at the MAT02FH:
Key Features:
Low Offset Voltage: 50 µV max.
Low Noise: 1.0 nV/√Hz max at 100 Hz, 1 mA.
High Gain: 500 min at IC=1 mA, 300 min at IC=1 μA.
Excellent Log Conformance: Low rBE (bulk resistance) of 0.3Ω.
Low Offset Voltage Drift: 0.1 µV/°C max.
Dual Transistor: Contains two monolithic NPN transistors.
TO-78 Package: A small, hermetically sealed metal package.
Applications:
Test Equipment: Oscilloscopes, function generators, spectrum analyzers.
Data Acquisition Systems: Multiplexed ADCs, DAQ boards.
Communication Systems: Transceivers, modems.
Medical Devices: Patient monitoring, imaging equipment.
Industrial Automation: PLCs, sensor networks.
General Purpose: Input stage for amplifiers, log/antilog circuits.
Additional Information:
The MAT02 series is known for its stability due to Analog Devices' Silicon Nitride "Triple Passivation" process.
It can be used as a direct replacement for the LM194/394
