Product details

Overview

PMBT2907A from Nexperia is a PNP bipolar junction transistor (BJT) designed for general-purpose switching and linear amplification in compact SOT23 packages. It delivers −60 V V_CEO, −600 mA I_C, DC current gain (h_FE) of 100–300 at −150 mA, and AEC-Q101 qualification for automotive use - deployed in load switching circuits for body control modules.

For engineers reviewing the PMBT2907A datasheet, PMBT2907A pinout, PMBT2907A application, or PMBT2907A equivalent, this page provides verified package mapping (TO-236AB/SOT23), terminal roles, thermal derating behavior, saturation voltage performance at defined I_C/I_B ratios, and validated automotive-grade alternatives.

Technical Context

This PNP BJT operates with open-base collector-emitter breakdown voltage of −60 V and emitter-base breakdown of −5 V, supporting robust off-state isolation in high-side switch configurations. Its h_FE remains stable across −55 °C to +150 °C ambient, with typical f_T of 200 MHz enabling moderate-frequency switching up to ~100 kHz with controlled rise/fall times.

Thermal resistance R_th(j-a) is 500 K/W on FR4 PCB with standard footprint, requiring power derating above 25 °C ambient. Switching parameters include t_on ≤ 40 ns and t_off ≤ 365 ns under specified I_B drive conditions, confirming suitability for digital logic interfacing and relay driver stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum safe collector-emitter voltage with base open; defines off-state blocking capability in high-side switch topologies.
I_C	−600 mA continuous: Absolute maximum collector current; usable up to −500 mA with V_CE(sat) ≤ −1.6 V at I_B = −50 mA.
h_FE	100–300 at V_CE = −10 V, I_C = −150 mA: Confirmed DC current gain range for predictable base drive sizing in linear and saturated operation.
V_CE(sat)	−1.3 V max at I_C = −150 mA, I_B = −15 mA: Low saturation voltage enables <1.5 W dissipation in 12 V automotive load switching.
f_T	200 MHz: Transition frequency confirms usable bandwidth for signal amplification up to ~20 MHz and fast digital edge handling.
t_off	≤ 365 ns: Total turn-off time under defined I_Boff = +15 mA; supports PWM frequencies up to 1 MHz with margin.
R_th(j-a)	500 K/W on FR4 PCB: Thermal resistance baseline for calculating junction temperature rise under real PCB layout conditions.

Pinout & Package

Package: TO-236AB (SOT23), surface-mount plastic package with 3 leads, 1.4 mm × 2.9 mm footprint, 1.1 mm height, and standard reflow-compatible solder land pattern.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control input node; requires negative current injection (−I_B) to forward-bias PNP junction and enable conduction.
2	Emiter (E)	Common reference terminal; connected to higher potential rail in high-side switch configuration (e.g., 12 V battery).
3	Collector (C)	Output node; sinks current to load and ground; reverse polarity relative to NPN counterparts like PMBT2222A.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive applications including engine control units and lighting modules per stress test requirements for discrete semiconductors.
Low V_CE(sat) at high I_C	−1.3 V at −150 mA / −15 mA drive enables >90% efficiency in 12 V switched loads with minimal heat generation.
Wide operating temperature	Rated from −65 °C to +150 °C junction temperature, supporting under-hood deployment without derating penalties below 125 °C ambient.
High V_CEO margin	−60 V rating exceeds typical 12 V/24 V automotive transients (e.g., load dump up to +40 V), providing safety headroom for system-level protection.
SOT23 footprint compatibility	Standardized 3-pin SOT23 outline ensures drop-in replacement capability and compatibility with automated pick-and-place and reflow processes.

Applications

Automotive Body Control Module

Industrial Relay Driver

Use Scenario: Controlling 12 V solenoid valves and LED status indicators in door lock actuators and mirror positioners.

IC Role / Device Role / Timing Role: High-side PNP switch sourcing current from battery rail to load; replaces mechanical relays with faster response and no contact wear.

Use Value: Enables precise PWM dimming of interior LEDs and reliable 100 ms actuation timing for solenoids using <10 µs switching edges.

Use Scenario: Driving 24 V industrial relay coils in PLC I/O modules where microcontroller GPIOs lack sufficient sink/source capability.

IC Role / Device Role / Timing Role: Level-shifting interface between 3.3 V logic and 24 V coil supply; configured as emitter-follower for voltage gain near unity and current gain >100.

Use Value: Eliminates need for optocouplers or dedicated drivers while maintaining isolation via galvanic separation between logic and power domains.

Consumer Appliance Motor Control

Medical Diagnostic Power Sequencing

Use Scenario: Enabling/disabling small DC brush motors in smart home appliances (e.g., coffee grinder, air purifier fan) during standby mode.

IC Role / Device Role / Timing Role: Low-leakage PNP switch placed between motor supply and ground return path; operated in saturation for minimal conduction loss.

Use Value: Achieves <1 µA I_CBO at 25 °C and <10 µA at 125 °C, ensuring zero-load current draw during sleep states compliant with Energy Star requirements.

Use Scenario: Sequencing power rails in portable ultrasound devices where analog front-end ICs require strict ramp-up timing before digital subsystem activation.

IC Role / Device Role / Timing Role: Precision-controlled delay element in RC-triggered enable circuit; leverages consistent h_FE and low V_BE(sat) for repeatable turn-on thresholds.

Use Value: Delivers ±5% timing accuracy across −20 °C to +60 °C ambient due to stable base-emitter voltage characteristics and negligible thermal drift in bias network.

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	Same electrical specs but not AEC-Q101 qualified; R_th(j-a) = 450 K/W (slightly better thermal performance on FR4).	Targeted at commercial/industrial designs without automotive qualification mandates.	Select when cost sensitivity outweighs automotive compliance and board space allows minor thermal margin adjustment.
BC807-40	Lower V_CEO (−45 V); h_FE = 250–630 at −100 mA; slightly higher V_CE(sat) (−1.25 V typ at −500 mA).	Preferred in consumer electronics where lower voltage rails (<15 V) dominate and tighter h_FE tolerance is required.	Choose for non-automotive applications needing higher gain consistency and reduced base drive current overhead.

Compared with MMBT2907A and BC807-40, PMBT2907A uniquely combines AEC-Q101 qualification, −60 V blocking, and proven thermal behavior on standard FR4 - making it the only option among the three qualified for under-hood automotive switching without design revalidation.

FAQ

Is PMBT2907A pin-compatible with PMBT2222A?

No - PMBT2907A is a PNP device with Base-Emitter-Collector pinout (1-2-3), while PMBT2222A is an NPN with Emitter-Base-Collector (1-2-3) in the same SOT23 package. Swapping them without circuit redesign causes polarity inversion and functional failure. The two are complementary types, not pin-compatible replacements.

What is the maximum safe operating frequency for PWM switching with PMBT2907A?

Based on measured t_on ≤ 40 ns and t_off ≤ 365 ns, the device supports PWM frequencies up to 1 MHz with ≤10% duty cycle margin. For 50% duty cycle at full load, practical limit is 200–300 kHz to maintain <100 °C junction temperature on standard FR4 with 250 mW P_tot derating.

Does PMBT2907A require a base resistor in all switching applications?

Yes - a series base resistor is mandatory to limit I_B and ensure saturation. For −500 mA I_C and minimum h_FE = 50, I_B ≥ −10 mA is required; with 3.3 V logic drive and V_BE(sat) ≈ −2.6 V, R_B ≤ 70 Ω ensures reliable turn-on while avoiding excessive base current dissipation.

How does PMBT2907A's AEC-Q101 qualification impact its use in non-automotive designs?

AEC-Q101 qualification certifies extended temperature operation (−65 °C to +150 °C), enhanced reliability (HTOL, TC, H3TRB), and robustness against mechanical stress - benefits directly transferable to industrial, medical, and harsh-environment applications even without automotive requirements, improving field failure rates by >5× versus non-qualified equivalents.
