Product details

Overview

PXT2907A,115 from Nexperia is a PNP bipolar junction transistor designed for medium-power switching and linear amplification in automotive and industrial control circuits. It delivers −60 V V_CEO, −600 mA I_C, DC current gain (h_FE) ≥100 at −10 mA, and AEC-Q101 qualification - enabling use in engine control modules, LED driver stages, and relay drivers where robust thermal performance and automotive-grade reliability are required.

For engineers reviewing the PXT2907A,115 datasheet, PXT2907A,115 pinout, PXT2907A,115 application, or PXT2907A,115 equivalent, key selection criteria include its SOT89 package thermal resistance (R_th(j-a) = 113 K/W with 6 cm² copper pad), low V_CE(sat) of −1.3 V at −150 mA/−15 mA drive, and guaranteed operation across −65 °C to +150 °C ambient.

Technical Context

This PNP transistor operates as a current-controlled switch or linear amplifier with fixed emitter-base and collector-base junctions. Its structure supports high-speed switching (t_on = 40 ns, t_off = 365 ns) and stable DC gain over temperature (h_FE = 100–300 at −150 mA, −2 V).

Thermal design is defined by three mounting configurations: standard footprint (1.1 W P_tot), 1 cm² collector pad (0.8 W), and 6 cm² pad (0.5 W). Junction-to-solder-point thermal resistance is fixed at 30 K/W, enabling precise PCB-level thermal modeling for automotive under-hood applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V - Maximum safe collector-emitter voltage with base open; defines breakdown margin in 12 V/24 V automotive load switching.
I_C	−600 mA continuous - Sustained collector current capability; supports driving solenoids, small relays, or LED strings up to ~10 W.
h_FE	100 min at −10 mA, −1 V - Ensures reliable saturation with modest base drive; enables direct MCU GPIO control without external buffer.
V_CE(sat)	−1.3 V max at −150 mA / −15 mA - Low conduction loss reduces heat generation in high-duty-cycle switching applications.
f_T	200 MHz - Supports RF pre-driver or fast digital signal switching up to ~20 MHz square waves with minimal distortion.
R_th(j-sp)	30 K/W - Fixed junction-to-solder-point thermal resistance; allows accurate thermal simulation when mounted on FR4 with exposed die pad.
AEC-Q101	Qualified - Meets stress test requirements for discrete semiconductors in automotive applications including temperature cycling, HTRB, and ESD.

Pinout & Package

SOT89 (SC-62/TO-243) plastic surface-mounted package with exposed die pad for enhanced thermal transfer. Dimensions: 4.6 × 2.6 × 1.6 mm (L × W × H); 3-lead configuration with lead pitch of 3.0 mm.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter (E)	Current exit node; connected to system ground or low-side return path; electrically tied to exposed die pad for thermal conduction.
2	Collector (C)	Current entry node; connects to load (e.g., relay coil or LED anode); requires copper pour for thermal dissipation per datasheet layout guidelines.
3	Base (B)	Control input; accepts current-limited drive (e.g., 15 mA typical for 150 mA collector); polarity-sensitive for PNP turn-on (negative relative to emitter).

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock per JESD22 standards.
Exposed die pad (SOT89)	Enables 30 K/W junction-to-solder-point thermal resistance; reduces thermal impedance by up to 73% vs. standard SOT23 packages.
Low V_CE(sat) at high I_C	−1.6 V max at −500 mA / −50 mA ensures <1 W power loss in 12 V relay driver stage operating at 80% duty cycle.
High f_T and fast switching	200 MHz f_T and 40 ns t_on support PWM dimming of LEDs at >10 kHz without audible noise or waveform degradation.
Wide operating temperature	Rated from −65 °C to +150 °C junction temperature; supports engine control units, transmission controllers, and battery management systems.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT2907A	SOT23 package; R_th(j-a) = 300 K/W; P_tot = 350 mW; no AEC-Q101 qualification.	Limited to low-power consumer or non-automotive industrial use due to lower thermal capability and qualification status.	Select when board space is constrained and thermal load ≤300 mW; not suitable for automotive under-hood deployment.
PN2907A	TO-92 through-hole package; P_tot = 625 mW; R_th(j-a) ≈ 200 K/W; AEC-Q101 not claimed.	Requires manual assembly and lacks SMT compatibility; unsuitable for automated high-volume production.	Choose only for prototyping or legacy through-hole designs where reflow compatibility is not required.

Compared with MMBT2907A and PN2907A, PXT2907A,115 uniquely combines SOT89 thermal performance (0.5 W P_tot with 6 cm² pad), AEC-Q101 qualification, and −600 mA rating - making it the only option qualified for high-reliability automotive switching where both power density and compliance are mandatory.

FAQ

What is the maximum allowable junction temperature for PXT2907A,115?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation beyond this limit causes permanent device degradation. Thermal design must ensure T_j remains ≤150 °C under worst-case ambient and power dissipation conditions, using the specified R_th(j-a) values for each PCB mounting configuration.

Can PXT2907A,115 be used as a direct replacement for MMBT2907A in existing SOT23 layouts?

No - PXT2907A,115 uses the larger SOT89 package (4.6 × 2.6 mm) with different pin spacing (3.0 mm pitch) and thermal pad requirements, making it mechanically incompatible with SOT23 footprints. Board redesign is required to accommodate the SOT89 outline, solder mask openings, and copper pour for the exposed die pad.

What base current is required to fully saturate PXT2907A,115 at 500 mA collector current?

Per datasheet Fig. 8 and Table 10, V_BE(sat) is −2.6 V max at I_C = −500 mA and I_B = −50 mA. Therefore, a minimum base drive of −50 mA is required for guaranteed saturation. With h_FE ≥50 at this condition, a design should target I_B ≥ −10 mA to ensure margin, but −50 mA is the validated saturation point.

Does PXT2907A,115 support pulsed operation beyond its DC current rating?

Yes - the datasheet specifies I_CM = −800 mA peak collector current for single pulses ≤1 ms. This allows short-duration surge handling (e.g., relay coil inrush, solenoid pull-in) beyond the −600 mA DC limit, provided average power stays within derated P_tot limits and pulse repetition avoids thermal accumulation.
