Suriace Mount Products = Discretes SOT 23 Microminiature Space Saving Alternatives for Discrete Devices A wide variety of discrete components from Motorola's repertoire of reliability-proven semicon- ductor processes and geometries are available in SOT (Small Outline Transistor) packages. Products include Bipolar and Field-Effect Transistors; Switch- ing, Zener and Varactor Diodes; and _ Silicon Controlled Rectifiers. The surface-mounted SOT devices are currently being used by circuit designers on Printed Circuit Boards and Ceramic Substrate. Some of the significant features of the SOT devices are: @ Complete Pretest Capability all SOTs are 100% electrically tested. @ Handling and Assembly Ease SOTs can be placed on substrates either manually or by using automated handling equipment. @ Reliability SOTs are subjected to the same rigid reliability test performed on all Motorola plastic packages. @ Small Size/Less Weight - Considerable size reduction and weight-saving is achieved in circuit designs using SOT technology. e@ Broad Line Currently, Motorola offers over 250 standard discrete devices in the SOT packages. (inquiries regarding customers special requirements are invited.) @ Marking Capability A multi-digit code is /aser marked on every SOT device. General-Purpose SOT-23 Transistors Pinout: 1-Base, 2-Emitter, 3-Collector @ Packaging Motorola standard shipping method for SOT's is in vials; additionally, in conjunction with the industry trend to use automatic placement equipment for microminiature components, Motorola offers the SOT-23 packaged in the 8mm tape and reel format. @ Standard SOT-23 VS Low Profile SOT-23 Motorola offers both the standard SOT-23 outline (TO-236AA) and the new Low Profile SOT-23 (TO-236AB). The only difference is the clearance from the bottom of the package to the surface of the substrate.
