2SC3838KT146P Equivalent & Substitute Parts Reference
Part Overview
The 2SC3838KT146P by Rohm Semiconductor is an NPN bipolar junction transistor (BJT) designed for radio frequency (RF) applications. It features an 11V collector-emitter maximum voltage, 50mA collector current, 3.2GHz transition frequency, 200mW power dissipation, and is supplied in a surface-mount TO-236-3 (SC-59, SOT-23-3, SMT3) package. This device is an active product with current inventory available. Alternative models may be required to ensure design flexibility, address supply chain fluctuations, or optimize sourcing strategy within the same electrical and mechanical specification constraints.
