ST MOS tube phone manufacturers, Fairchild authentic imported MOS tube FQA9N90C, brand FAIRCHILD / Fairchild Model FQA9N90C kind of insulated gate (MOSFET), channel type MOSFET N-channel metal-oxide-enhanced conductivity mode uses A / wideband amplification, Package Outline P-DIT / plastic dual in-line material N-FET N-channel silicon. Because the base is thin, the reverse recovery charge is small, so fast recovery diode reverse recovery time is shorter, lower forward voltage drop and reverse breakdown voltage (voltage value) high. ST MOS tube phone manufacturers, the diode, the voltage applied to both ends of the forward to reverse the change, the response time is very short, and contrary to the reverse. Fast recovery diodes (abbreviated FRD) is a kind of switching characteristics of a good, short reverse recovery time characteristics of a semiconductor diode, mainly used in electronic circuit switching power supplies, PWM pulse width modulation, frequency converters, etc., as a high-frequency rectifier diodes, freewheeling diodes or damping diode use, fast recovery diodes internal structure and ordinary PN junction diode is different, it belongs to the PIN junction diode, namely in the middle of the P-type and N-type silicon material silicon material increases the base region I, composed of silicon PIN . Over the years the company holds to talent development, to promote effective management, quality of survival, to win market services, a fair popular philosophy, the only sales of imported genuine business line, growing the company's business, won the majority of the trust of users, the establishment of a stable and cooperative relations in the domestic electronic components industry has a certain market. We will do better in the future, high-quality products and quality service and better return on new and old customers.
