The MMBT3906-7-F from Diodes Incorporated is a PNP general-purpose bipolar junction transistor rated for -40V collector-emitter voltage and -200mA collector current, housed in the industry-standard SOT-23. This small-signal switching transistor features epitaxial planar die construction with a current gain (hFE) of 100 minimum at 10mA and 30 minimum at 100mA, delivering a transition frequency of 250MHz for fast signal processing. The device exhibits low saturation voltage of -0.25V maximum at -10mA and -0.40V at -50mA, making it suitable for efficient switching circuits. Specified across the full -55°C to +150°C operating temperature range with 300mW power dissipation and 417°C/W thermal resistance, this RoHS-compliant PNP transistor serves as the SOT-23 complement to the widely-used MMBT3904 NPN type in countless low-power designs.
Application Scenarios
The MMBT3906-7-F PNP transistor is deployed as a general-purpose amplifier and switch in consumer electronics, industrial controls, and communication equipment. Typical applications include low-power audio amplification stages, LED driver circuits, relay driver interfaces, voltage regulators, and inverter circuits. The complementary PNP/NPN pairing with MMBT3904 supports Class-B audio output stages, H-bridge motor drivers, and logic-level translation circuits. In portable and battery-powered devices, this small-signal transistor handles bias supply circuits, timer functions, and audio mute switching. Additional use cases cover telecom wireline interface circuits, infrared diode amplifiers, and general PNP switching in dense PCB layouts where SOT-23 footprint minimizes board space.
Frequently Asked Questions
Q1: What is the difference between MMBT3906-7-F and MMBT3906Q? Both share identical electrical specifications (-40V, -200mA, SOT-23), but the Q version is AEC-Q101 automotive qualified and PPAP capable for high-reliability vehicle applications.
Q2: What is the complementary NPN transistor? The MMBT3904-7-F is the electrically complementary NPN type with matching SOT-23 package and similar specifications for push-pull pair designs.
Alternative BJT Transistor Models
