FMBM5551

The FMBM5551 is a high-performance, medium-power bipolar npn transistor array. It is designed for general purpose linear applications such as low voltage amplifiers, driver circuits and switches.The device consists of two emulator-temperature independent transistors (ETIATs). An ETIAT is an optimized three-terminal device combining a transistor, a JFET, and a Schottky diode. The combination provides excellent electrical performance over the whole operating temperature range and simplifies design by eliminating essential components from the circuit.The FMBM5551 has a high maximum output current of 4.4 mA and an On-resistance of 7.4Ω, making it suitable for use as a low-impedance switch. In addition, it has low offset voltage and good thermal stability, making it suitable for use in linear applications. The FMBM5551 also has a reverse voltage of -2.8 V and a leakage current of 1 nA.Working PrincipleThe FMBM5551 is an integrated duplex emitter-coupled transistor array, with each transistor consisting of an emitter, a base, and a collector. The base of each transistor is connected to a common emitter terminal, while the emitters and collectors of each pair of transistors are connected to different collector terminals. Each pair of transistors is then connected to a supply voltage and the outputs are provided from the collector terminals.The transistors of the array are biased via a resistor connected between the base and the supply voltage. When a signal is applied to the base, it causes the transistors to switch on, resulting in a current flow between the emitters and the collectors. This current is then amplified by the two transistors and is output from the collector terminals.The FMBM5551 can be used in a variety of linear and switching applications due to its high output current and low-resistance characteristics. In linear applications, it can be used to amplify small signals or as a low-impedance switch. In switching applications, it is used as a means of switching higher-current signals.ConclusionThe FMBM5551 is a high-performance, medium-power bipolar npn transistor array designed for general-purpose linear applications such as low-voltage amplifiers, driver circuits, and switches. It has a high maximum output current of 4.4 mA and a low offset voltage. In addition, it has good thermal stability, low on-resistance, and a reverse voltage of -2.8 V. The FMBM5551 can be used in various linear and switching applications due to its high output current and low-resistance characteristics.
