BC817K NPN General-Purpose Transistors

Nexperia BC817K NPN General-Purpose Transistors are AEC-Q101 qualified devices with three current gain selections. These transistors incorporate high-power dissipation capability. The Nexperia BC817K NPN general-purpose transistors come in a small SOT23 (TO-236AB) Surface-Mounted Device (SMD) plastic package. These devices are ideally used in general-purpose switching and amplification.

SOT23 Surface-Mounted Package Products

Nexperia SOT23 Surface-Mounted Package Products are contained in a plastic, surface-mounted, three terminals, 1.9mm pitch, 2.9mm x 1.3mm x 1mm package. This mainstay package in semiconductors was introduced in 1969 and quickly became an industry standard. The SOT23 encapsulates an extensive range of diodes, bipolar transistors, MOSFETs, and ESD protection devices within Nexperia's portfolio. The SOT23 package has been a constant for the last 50 years, leading to several offspring, such as the SOT223 and SOT323.

SOT323 Surface-Mounted Package Products

Nexperia SOT323 Surface-Mounted Package Products offer a plastic, 3 leads, 1.3mm pitch, 2mm x 1.25mm x 0.95mm body surface-mounted package. The SOT23 package has been a constant for the last 50 years, leading to many offspring, such as the SOT223 and SOT323. The SOT323 offers an industry code of SC-70, a descriptive code of SOT (small outline transistor), and a footprint area of 6.23mm².
