Product details

Overview

MMST2907A-7-F from Diodes Incorporated is a 60V PNP small-signal transistor in SOT323 package, rated for -600mA collector current, -60V V_CEO, and 200mW power dissipation. It features epitaxial planar die construction, AEC-Q101 qualification, and is used in automotive load switching, discrete logic level translation, and low-power analog amplification circuits.

For engineers reviewing the MMST2907A-7-F datasheet, MMST2907A-7-F pinout, MMST2907A-7-F application, or MMST2907A-7-F equivalent, key selection criteria include V_CEO rating, h_FE variation across I_C, V_CE(SAT) at high current, thermal resistance (625°C/W), and AEC-Q101 compliance for automotive-grade reliability.

Technical Context

This PNP bipolar junction transistor operates with emitter-base forward bias and collector-base reverse bias in active or saturation mode. Its design supports linear amplification (h_FE = 75–300 at I_C = -100µA to -500mA) and fast switching (t_ON = 45ns, t_OFF = 100ns) under pulsed conditions (≤300µs, ≤2% duty cycle).

Thermal performance is defined for a single-sided 1.6mm FR4 PCB with 1oz copper pad layout under still-air conditions. ESD robustness includes 4kV HBM and 400V MM ratings, and it uses matte tin-plated leads solderable per MIL-STD-202, Method 208.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-60V - Maximum allowable voltage between collector and emitter before breakdown, critical for automotive 42V system margin
I_C	-600mA - Continuous DC collector current handling capacity, defines maximum load drive capability
P_D	200mW - Steady-state power dissipation limit on standard PCB layout, constrains thermal design
h_FE	75–300 - DC current gain range across operating currents, impacts base drive sizing and stability
V_CE(SAT)	-0.4V to -1.6V - Saturation voltage at I_C = -150mA/-500mA, determines conduction loss in switch applications
f_T	200MHz - Transition frequency at V_CE = -20V, I_C = -50mA, sets upper bandwidth limit for RF/switching use
R_θJA	625°C/W - Junction-to-ambient thermal resistance, defines temperature rise per watt on reference board

Pinout & Package

Package: SOT323 - ultra-small surface-mount plastic package (2.15 × 2.10 × 0.95 mm), moisture sensitivity level 1, UL 94V-0 rated, weight ≈ 0.006 g.

Pin/Terminal	Circuit Role	Design Meaning

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
BC807-40,115 (Nexperia)	V_CEO = -45V; h_FE min = 250 @ I_C = -100mA; SOT23 package	Lacks AEC-Q101 qualification; lower voltage rating limits 42V system use	Prefer where cost-sensitive industrial designs accept reduced transient margin
PN2907A (ON Semiconductor)	TO-92 through-hole package; same V_CEO/I_C specs; no AEC-Q101 or green compliance	Not suitable for automated SMT assembly; incompatible with high-density PCB layouts	Select only for legacy through-hole prototyping or repair scenarios

Compared with BC807-40,115 and PN2907A, MMST2907A-7-F uniquely combines AEC-Q101 qualification, SOT323 miniaturization, and -60V rating-making it the only choice for new automotive SMT designs requiring both reliability and space efficiency.

FAQ

Is MMST2907A-7-F suitable for automotive applications?

Yes. It is fully AEC-Q101 qualified and PPAP capable, with testing performed per stress test conditions for temperature cycling, humidity, and mechanical shock. Its -60V V_CEO, 150°C max operating temperature, and green material composition meet automotive electronics requirements for body control, lighting, and power distribution modules.

What is the recommended PCB pad layout for SOT323?

Diodes specifies a minimum 1oz copper pad layout on single-sided 1.6mm FR4 for thermal derating. Recommended dimensions are C = 0.65mm, G = 1.30mm, X = 0.47mm, Y = 0.60mm, and Y1 = 2.50mm. These ensure proper solder fillet formation, thermal conduction, and mechanical reliability during reflow and thermal cycling.

How does h_FE vary with collector current?

h_FE ranges from 75 at I_C = -100µA to 100 at I_C = -1mA, peaks at 300 at I_C = -150mA, then drops to 50 at I_C = -500mA. This nonlinearity must be accounted for in base resistor calculations-especially in saturation-switching designs where gain collapse affects drive margin.

Can MMST2907A-7-F replace MMST2222A in circuit designs?

No-it is the complementary PNP to the NPN MMST2222A, not a drop-in replacement. Swapping them without reversing biasing and signal polarity will prevent circuit operation. They are intended for matched-pair use in push-pull stages, differential amplifiers, or complementary switching topologies-not interchangeable substitution.
