The text above indicates that this package is used by either transistors or FETs but almost any two or three-terminal semiconductor could use this package: Thyristors, IGBTs, and so on. SOT-23 is used for small-signal transistors and measures 2.9 mm x 2.4 mm x 1.1 mm.īecause the SOT-23 is a Surface Mount Device heat transfer will also be conducted via the component leads. The SOT-23 or TO-236AB package is a 3-terminal plastic surface mount component.Ī similar package style is the TO-236AA SMD Transistor In addition to bipolar, bipolar Darlington, and power MOSFET transistors. Our power transistor portfolio includes power MOSFETs, silicon carbide (SiC) MOSFETs, GaN Transistors, IGBTs and a wide range of power bipolar transistors. These devices operate at DC or relatively low (audio) frequencies so, the TO-220 package is not intended for devices operating at radio frequencies. The TO-220 case is found on semiconductor devices handling less than 100 amperes and operating at less than a few hundred volts. RF power transistors directly from factory all types listed together. The typical lead pitch (distance between leads) of a TO-220 package is 2.54 mm.Ĭommon transistors that use the TO-220 package Transistor clamp model A LDMOS RF transistors in various cases. Due to the multitude of applications and fitment issues with the driveline components there is no online catalog available. The metal tab at the back of the TO-220 serves as a heat sink itself, but it has a hole so that it can be screwed onto a larger heat sink if higher power handling capability is required.Ī typical TO-220 package can have 2 to 7 leads, although TO-220's with 3 leads are most commonly encountered because this package is primarily used on three-terminal devices such as transistors. All units are completely tested before shipping. J3Y TransistorS8050 NPN SOT-23 SMD 0.5A 40V Transistor PN2222A, a "plastic" version of the original 2N2222 Unfortunately, this small size means that it is not designed to dissipate much heat and can not be used on devices that have high power consumption The main advantage of the TO-92 package is its small size. Since it is most often used in transistor packaging, the TO-92 usually has three leads, all of which come out from the bottom of the package. It has a flat front face that is marked with the device name or number, while its back is semi-circular in shape. The TO-92 is a small type of plastic-molded package.
