TO-92

Package: TO-92_Inline Library: Package_TO_SOT_THT Category: Transistor Package 3D Model: TO-92_Inline.step Format: STEP

Description

The TO-92 is the most recognizable through-hole transistor package, with its distinctive semicircular cross-section. Three inline leads at 1.27mm pitch house small-signal BJTs (2N2222, 2N3904), voltage references (LM385), temperature sensors (DS18B20), and small MOSFETs. At roughly 4.2 x 3.8mm, the molded epoxy body provides basic power dissipation up to 625mW. The 3D model shows the flat face with part marking and curved back.
