Product details

Overview

MMBT5401Q-7-F from Diodes Incorporated is a 150V PNP high-voltage general-purpose transistor in SOT23 package, rated for -600mA collector current and -150V V_CEO, with DC current gain (h_FE) of 50–240 at -1mA to -50mA, optimized for low-power switching and amplification in automotive-compliant signal conditioning circuits.

For engineers reviewing the MMBT5401Q-7-F datasheet, MMBT5401Q-7-F pinout, MMBT5401Q-7-F application, or MMBT5401Q-7-F equivalent, this part supports high-reliability designs requiring JEDEC-qualified PNP switching with verified -160V V_CBO, 310mW power dissipation, and ESD HBM rating of 4kV.

Technical Context

This PNP bipolar junction transistor uses epitaxial planar die construction for stable high-voltage operation and thermal robustness across -55°C to +150°C ambient range. Its complementary NPN counterpart is MMBT5551, enabling matched pair design in differential or push-pull configurations.

The device delivers f_T of 100–300MHz at -10mA and exhibits V_CE(sat) ≤ -0.5V at -50mA/-5mA drive, supporting fast-switching applications where low saturation voltage and predictable gain-bandwidth trade-offs are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-150V - Maximum safe collector-emitter blocking voltage under open-base conditions
I_C	-600mA - Continuous DC collector current limit before thermal derating begins
h_FE	50–240 - DC current gain range across -1mA to -50mA, enabling bias stability in amplifier stages
V_CE(sat)	≤ -0.5V @ -50mA/-5mA - Low on-state voltage drop ensures minimal conduction loss in switching nodes
f_T	100–300MHz - Gain-bandwidth product defining usable frequency limit for small-signal amplification
ESD HBM	4,000V - Human Body Model rating confirming robustness against common handling electrostatic discharge
R_θJA	403°C/W - Junction-to-ambient thermal resistance on minimum pad layout, guiding PCB copper area requirements

Pinout & Package

Package: SOT23 - Surface-mount plastic package with 3-pin configuration, 0.008g mass, UL 94V-0 flammability rating, and matte tin-plated leads solderable per MIL-STD-202.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT5401-7-F	Non-automotive grade; same electrical specs but not AEC-Q qualified	Suitable for commercial/industrial use only; lacks automotive reliability documentation	Select when automotive qualification is not required and cost sensitivity is high
PN2907A	Higher V_CEO (-60V), lower h_FE (100 typ), TO-92 package	Larger footprint, lower voltage capability, less suitable for space-constrained automotive PCBs	Choose only if legacy through-hole assembly is mandated and voltage margin is sufficient

Compared with MMBT5401-7-F and PN2907A, the MMBT5401Q-7-F provides identical electrical performance plus AEC-Q validation-enabling drop-in use in automotive signal chains without requalification, while its SOT23 footprint supports modern high-density layouts unattainable with TO-92 alternatives.

FAQ

What is the maximum allowable collector-emitter voltage for MMBT5401Q-7-F?

The absolute maximum V_CEO is -150V at T_A = +25°C with open base. Derating applies above +25°C ambient per the datasheet's thermal curve; at +100°C, the practical safe operating limit reduces to approximately -120V to maintain reliability margins under sustained load.

Is MMBT5401Q-7-F pin-compatible with standard SOT23 PNP transistors?

Yes-MMBT5401Q-7-F uses standard SOT23 pinout (Emitter-Base-Collector on pins 1-2-3), matching industry-standard layout footprints. It is mechanically and electrically compatible with other SOT23-packaged PNP transistors like MMBT3906, though electrical parameters (e.g., V_CEO, h_FE) differ and must be verified per circuit requirements.

Does MMBT5401Q-7-F require external heat sinking in typical applications?

No-its 310mW power dissipation rating on minimum pad layout and 403°C/W R_θJA allow operation up to ~100mA continuous current without added thermal relief. For currents exceeding 200mA or ambient temperatures above +70°C, increased copper area or thermal vias are recommended per the derating curve.

How does the "Q" suffix in MMBT5401Q-7-F affect its specifications?

The "Q" denotes automotive qualification per AEC-Q101 standards, including extended temperature testing (-55°C to +150°C), accelerated life testing, and failure analysis protocols. Electrical parameters remain identical to non-Q versions; only reliability validation and traceability documentation differ.
