Product details

Overview

MMBT2907A-7 from Diodes Incorporated is a 60V PNP small-signal transistor in SOT23 package, rated for -600mA continuous collector current and -60V V_CEO, with DC current gain (h_FE) of 75–300 at I_C = -10mA to -500mA, optimized for low-power switching and amplification in automotive and industrial control circuits.

For engineers reviewing the MMBT2907A-7 datasheet, MMBT2907A-7 pinout, MMBT2907A-7 application, or MMBT2907A-7 equivalent, key selection criteria include V_CEO/V_CBO rating, saturation voltage under defined I_C/I_B, thermal resistance (R_θJA = 403°C/W), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This PNP bipolar junction transistor uses epitaxial planar die construction to ensure stable gain and low leakage across temperature. Its complementary NPN counterpart is MMBT2222A, enabling matched pair design in differential amplifiers and push-pull stages.

It operates over -55°C to +150°C with 4kV HBM ESD rating and supports switching applications with t_ON = 45ns, t_OFF = 100ns, and f_T = 200MHz at V_CE = -20V, I_C = -50mA - confirming suitability for medium-speed digital logic interfacing and analog signal conditioning.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-60V - maximum safe collector-emitter voltage before breakdown in common-emitter configuration
I_C (continuous)	-600mA - maximum DC collector current without thermal derating at T_A = 25°C
h_FE	75–300 - DC current gain range across I_C = -100µA to -500mA, critical for bias stability
V_CE(SAT)	-0.4V @ I_C = -150mA, I_B = -15mA - low saturation voltage enables efficient switching with minimal power loss
f_T	200MHz - transition frequency defining usable bandwidth for RF and high-speed switching
R_θJA	403°C/W - thermal resistance from junction to ambient on minimum pad layout, guides PCB copper area requirements
ESD HBM	4,000V - human-body-model robustness supporting handling in non-ESD-controlled assembly environments

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current source terminal in PNP operation	Connected to higher potential; defines current flow direction and bias polarity
2 (Base)	Control input for minority-carrier injection	Requires negative bias relative to emitter to turn on; governs I_C via h_FE
3 (Collector)	Current sink terminal in PNP operation	Typically tied to load or ground-referenced circuit node; carries switched/signal current

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive applications including engine control modules and body electronics
Green compound packaging	Halogen- and antimony-free mold compound (<900ppm Br/Cl, <1000ppm Sb) meeting RoHS 2 compliance
Low V_CE(SAT) at high I_C	-1.6V @ I_C = -500mA ensures minimal conduction loss in power-switching roles
High f_T and fast switching	200MHz f_T with t_OFF = 100ns supports use in >1MHz PWM drivers and signal routing
Moisture sensitivity Level 1	No bake required prior to reflow; compatible with standard SMT assembly processes

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
PN2907A	TO-92 through-hole package; identical electrical specs but higher R_θJA (~200°C/W less effective cooling)	Limited to prototyping or low-volume board-level repair; not suitable for automated SMT production	Select when manual assembly or legacy footprint compatibility is required
BC807-40	SOT23 package; h_FE min = 250 (vs. 75 for MMBT2907A-7); V_CEO = -45V (vs. -60V)	Better gain consistency at low I_C, but lower voltage margin limits use in 48V industrial systems	Select for high-gain, low-current bias networks where voltage headroom ≥45V suffices

Compared with PN2907A and BC807-40, the MMBT2907A-7 delivers optimal balance of voltage rating, thermal performance in SMT format, and AEC-Q101 validation - making it preferred for automotive and high-reliability industrial designs requiring both robustness and manufacturability.

FAQ

What is the maximum operating temperature for MMBT2907A-7?

The MMBT2907A-7 is rated for junction and storage temperatures from -55°C to +150°C. Its thermal resistance R_θJA is 403°C/W on minimum pad layout, meaning sustained operation at +150°C requires careful PCB thermal design and derating above 25°C ambient.

Is MMBT2907A-7 pin-compatible with MMBT2222A?

No - MMBT2907A-7 is a PNP transistor with emitter-base-collector pinout (1-2-3), while MMBT2222A is an NPN device with collector-base-emitter pinout (1-2-3) in SOT23. They are complementary types, not pin-compatible; swapping them without circuit revision will cause functional failure.

Does MMBT2907A-7 require special handling for moisture sensitivity?

No - the device is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and does not require baking before reflow soldering. Standard SMT assembly processes apply without modification.

Can MMBT2907A-7 replace older 2N2907A in SOT23 form factor?

Yes - MMBT2907A-7 is the SOT23 surface-mount equivalent of the through-hole 2N2907A, sharing identical electrical specifications (V_CEO, h_FE, I_C, etc.) and adding AEC-Q101 qualification, RoHS compliance, and improved thermal metrics for modern manufacturing.
