Alfa Rpar - AS3944D - Array of 4 Matched NPN transistors
Product number:
103133SO14
Product information "Alfa Rpar - AS3944D - Array of 4 Matched NPN transistors"
AS3944 is an array of 4 NPN transistor that offers excellent matching for precision amplifier and nonlinear applications. Performance characteristics include high gain over a wide
range of collector current and Vcb, and excellent logarithmic conformance. AS3944 also features of low offset voltage μV and tight current gain matching. Each transistor is individually tested to data sheet specifications.
For matching parameters (offset voltage, input offset current, and gain match), each of the dual transistor combinations are verified to meet stated limits. The long-term stability of matching parameters is guaranteed by the protection diodes across the base-emitter junction of each transistor. These diodes prevent degradation of beta and matching characteristics due to reverse bias base-emitter current. Logarithmic conformance and accurate matching characteristics makes AS3944 an excellent choice for use in log and antilog circuits.
Features:
• low offset voltage 200 μV
• high current gain 400
• matching guaranteed for all transistors

Safety Instructions for Electronic and Mechanical Components
Intended Use:
• Electronic components, including potentiometers, knobs, switches, connectors, resistors, capacitors or integrated circuits (ICs), are designed for use in electronic circuits and devices.
• Use these components only for their intended purposes in electrical and electronic applications, according to their specified voltage, current, and environmental conditions.
• Any use outside the intended applications may result in malfunction or safety risks.
Handling and Installation
Installation:
• Handle electronic components with appropriate tools, such as tweezers, to avoid physical damage or exposure to electric shock.
• Ensure that the components are installed in the correct orientation and according to manufacturer specifications to avoid malfunction or damage to the circuit.
Storage:
• Store components in a dry, cool, and static-free environment to avoid damage from moisture, extreme temperatures, or electrostatic discharge (ESD).
• Avoid direct exposure to sunlight, which could affect component stability and performance.
Protection from Static Electricity:
• Use antistatic equipment (e.g., wrist straps, ESD mats) when handling electronic components to prevent electrostatic discharge, which can damage sensitive devices like ICs.
Compatibility:
• Make sure electronic components are compatible with the circuit in terms of voltage, current, and other technical specifications.
Warnings
Electrical Shock Hazard:
• Some components can retain charge even when disconnected. Use appropriate tools and take precautions when handling components to minimize the risk of electric shock.
Burn or Fire Risk:
• Overloading or misusing electronic components may result in overheating, which could lead to burning or fires. Ensure that components are used within their specified voltage and current ratings.
Danger from Misuse:
• Incorrect handling or use outside specified limits can damage the components or affect the performance and functionality of connected devices. Only use components within their specified tolerances and conditions.
Choking Hazard:
• Small electronic components can pose a choking hazard if swallowed. Keep components out of reach of children.
