MUN2114T1G

MUN2114T1G Description

The MUN2114T1G from onsemi is a surface-mount, pre-biased PNP bipolar transistor designed for efficient switching and amplification in low-power applications. Encased in a compact SC-59 package, it integrates 10 kΩ base (R1) and 47 kΩ emitter-base (R2) resistors, simplifying circuit design by eliminating external biasing components. With a collector-emitter breakdown voltage of 50V and a maximum collector current of 100mA, it delivers reliable performance in space-constrained designs. The device boasts a low Vce saturation voltage of 250mV (at 300µA Ib, 10mA Ic) and a high DC current gain (hFE) of 80 (at 5mA, 10V), ensuring energy efficiency and signal integrity. Compliant with ROHS3 and REACH, it meets stringent environmental standards.
