MMBTA92-TP

Single Bipolar Transistors Overview

The MMBTA92-TP is a PNP silicon high-voltage transistor manufactured by Micro Commercial Components (MCC). It operates within a junction temperature range of -55°C to +150°C. Key electrical ratings include a collector-emitter voltage (VCEO) and collector-base voltage (VCBO) of -300 V, an emitter-base voltage (VEBO) of -5 V, and a continuous collector current (IC) of -300 mA with a peak current (ICM) of -500 mA. Power dissipation is rated at 225 mW on an FR-5 board and 300 mW on an alumina substrate. The transition frequency (fT) is 50 MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source when purchasing the MMBTA92-TP, as this part number may be produced by multiple semiconductor manufacturers including MCC, onsemi, NXP, and others. Confirm that the datasheet parameters match your circuit requirements, particularly regarding power dissipation limits and saturation voltages, which vary between suppliers. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.

Single Bipolar Transistors Selection Notes

Select the MMBTA92-TP for applications requiring a compact PNP transistor with high voltage blocking capabilities in a SOT-23 package. Consider the thermal resistance values of 556°C/W and 417°C/W when designing heat dissipation strategies. Verify that the required DC current gain (hFE) falls within the specified ranges of 60 to 200 depending on the operating current conditions.

Single Bipolar Transistors Part Context

The MMBTA92 series comprises PNP high-voltage transistors designed for surface-mount applications. While the base MMBTA92 designation is used by various manufacturers such as onsemi and Nexperia, the MMBTA92-TP specifically denotes the version produced by Micro Commercial Components. These devices serve as complements to NPN counterparts like the MMBTA42 in general-purpose switching and amplification circuits.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other MMBTA92 variants from different manufacturers, noting that specifications such as power dissipation and hFE minimums differ significantly between sources like onsemi and MCC.
