Product details

Overview

MMBT2907AWT1 from onsemi is a PNP silicon general-purpose transistor in SC-70/SOT-323 package, rated for −60 V V_CEO, −600 mA I_C, and 150 mW power dissipation, with DC current gain (h_FE) up to 340 at −10 mA, used in low-power amplifier and switching circuits in automotive and industrial control modules.

For engineers reviewing the MMBT2907AWT1 datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, −60 V breakdown rating, SC-70 thermal resistance of 833 °C/W, and verified switching performance with t_on ≤ 45 ns and t_off ≤ 100 ns.

Technical Context

This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with defined V_CE(sat) ≤ −0.4 V at −150 mA/−15 mA drive and V_BE(sat) ≤ −1.3 V under same conditions. Its f_T = 200 MHz supports RF-coupled preamplifier stages and high-speed digital switching.

Thermal design is constrained by R_JA = 833 °C/W on FR-5 board, requiring careful layout for ambient temperatures up to +150 °C junction limit. C_ibo = 30 pF and C_obo = 8.0 pF define small-signal impedance matching at V_EB = −2.0 V and V_CB = −10 V respectively.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V - Maximum collector-emitter voltage before breakdown in common-emitter configuration
I_C	−600 mA - Continuous collector current handling capability without thermal runaway
P_D	150 mW - Total device dissipation on FR-5 board at 25°C ambient
h_FE	50–340 - DC current gain range across −0.1 to −500 mA collector currents
f_T	200 MHz - Current-gain bandwidth product defining usable frequency limit for amplification
t_off	≤ 100 ns - Maximum turn-off time enabling ≥5 MHz switching in saturated logic interfaces
R_JA	833 °C/W - Junction-to-ambient thermal resistance limiting power derating above 25°C

Pinout & Package

MMBT2907AWT1 uses the SC-70 (SOT-323) surface-mount package with 3 terminals, optimized for space-constrained PCB layouts and automated assembly. Pin 1 is Base, Pin 2 is Emitter, Pin 3 is Collector per onsemi Case 419-04, Style 3 mechanical drawing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-40W	Higher h_FE min (250 vs. 75), same SC-70 package, −45 V V_CEO	Preferred where higher DC gain stability is required at low I_C; not suitable for −60 V rail designs	Select BC807-40W only if system voltage remains ≤ −45 V and gain consistency below −1 mA is critical
PN2907A	TO-92 through-hole package, identical electrical specs except R_JA = 200 °C/W	Used in prototyping or legacy through-hole assemblies; lacks AEC-Q101 qualification	Choose PN2907A for breadboarding or non-automotive production where thermal budget allows larger package

Compared with BC807-40W and PN2907A, MMBT2907AWT1 uniquely combines AEC-Q101 compliance, −60 V rating, and SC-70 footprint-making it the only option qualified for automotive surface-mount implementations requiring full voltage margin and reliability validation.

FAQ

What is the maximum junction temperature rating for MMBT2907AWT1?

The MMBT2907AWT1 has a specified junction and storage temperature range of −55°C to +150°C. This rating is validated per onsemi's thermal characterization on FR-5 board and supports operation in under-hood automotive environments. Derating of power dissipation begins above 25°C ambient according to the 833 °C/W R_JA value. The MMBT2907AWT1 must be mounted with recommended pad layout to maintain this thermal performance.

Is MMBT2907AWT1 suitable for automotive applications?

Yes, MMBT2907AWT1 is AEC-Q101 qualified and PPAP capable, with NSV prefix variants (e.g., NSVMMBT2907AWT1G) explicitly designated for automotive use. It meets stress testing requirements for temperature cycling, humidity, and mechanical shock. The MMBT2907AWT1 is commonly deployed in body control modules, lighting drivers, and sensor interface circuits where reliability under harsh conditions is mandatory.

What is the pin configuration of MMBT2907AWT1 in the SC-70 package?

The MMBT2907AWT1 uses SC-70 (SOT-323) package with Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector, per onsemi Case 419-04 Style 3. This configuration is confirmed in the mechanical drawings and marking diagram of the official datasheet. The MMBT2907AWT1 pinout differs from alternate styles (e.g., Style 6 or Style 7), so PCB layout must strictly follow Style 3 alignment.

Does MMBT2907AWT1 have RoHS and halogen-free compliance?

Yes, MMBT2907AWT1 is Pb-free, halogen-free/BFR-free, and fully RoHS compliant per Directive 2011/65/EU. The "G" suffix in part numbers like MMBT2907AWT1G indicates lead-free packaging, and onsemi certifies material content per JEDEC JS709B. The MMBT2907AWT1 meets environmental compliance requirements for global electronics manufacturing without exemptions.

What is the DC current gain (h_FE) range for MMBT2907AWT1 at different collector currents?

The MMBT2907AWT1 exhibits h_FE = 75–340 depending on operating point: minimum 75 at −0.1 mA, 100 at −1.0 mA and −10 mA, 100 at −150 mA, and 50 at −500 mA (all at V_CE = −10 V). This variation is documented in the Electrical Characteristics table and Typical Characteristics Figure 3. Designers must select bias points within this validated h_FE envelope when using the MMBT2907AWT1 in linear amplifier or precision switching applications.
