2N3906S Description

Short technical summary and product information.

The KEC 2N3906S is an epitaxial planar PNP transistor suitable for general purpose and switching applications. It features low leakage current, with ICEX and IBL rated at a maximum of 50nA at VCE=-30V and VEB=-3V. The transistor exhibits excellent DC current gain linearity and a low saturation voltage, VCE(sat), of -0.4V (Max.) at IC=-50mA and IB=-5mA.

With a collector-emitter breakdown voltage (VCEO) of -40V and a collector current (IC) rating of -200mA, the 2N3906S is a complementary part to the 2N3904S. It operates within a junction temperature range of -55°C to 150°C and is housed in a compact SOT-23 surface-mount package.

Key electrical characteristics include a transition frequency (fT) of 250MHz and a low collector output capacitance (Cob) of 4.5pF (Max.). The device also offers a noise figure of 4.0dB (Max.). Switching times are specified with a delay time (td) and rise time (tr) of 35ns, and a storage time (tstg) and fall time (tf) of 225ns and 75ns respectively.
