Product details
Overview
PMBT2907A-QR from Nexperia is a qualified AEC-Q101 PNP bipolar junction transistor in SOT23 package, rated for −60 V VCEO, −600 mA IC, and DC current gain (hFE) of 100–300 at −150 mA/−10 V. It serves as a general-purpose switching device in automotive power control circuits, including body electronics load switching and LED driver bias stages.
For engineers reviewing the PMBT2907A-QR datasheet, PMBT2907A-QR pinout, PMBT2907A-QR application, or PMBT2907A-QR equivalent, key selection criteria include verified automotive qualification, SOT23 thermal derating behavior, collector-emitter saturation voltage under −500 mA drive, and complementary pairing with PMBT2222A-Q for push-pull designs.
Technical Context
This PNP transistor operates in active and saturation regions for discrete switching and linear amplification. Its design supports base-driven operation with guaranteed hFE ≥100 at −150 mA and VCE = −10 V, and VCEsat ≤ −1.6 V at −500 mA/−50 mA IB.
Thermal performance is defined for FR4 PCB mounting: Rth(j-a) = 500 K/W, with power derating to zero at 150 °C ambient. Absolute maximum ratings include −60 V VCBO, −5 V VEBO, and 250 mW Ptot at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V - Maximum safe collector-emitter voltage with base open; defines high-side switch headroom in 48 V automotive systems. |
| IC | −600 mA - Continuous DC collector current rating; supports medium-power relay drivers and fan control stages. |
| hFE | 100–300 - DC current gain range at −150 mA/−10 V; enables predictable base resistor sizing for reliable saturation. |
| VCEsat | ≤ −1.6 V at −500 mA/−50 mA - Low saturation voltage reduces conduction loss in high-duty-cycle switching applications. |
| fT | 200 MHz - Transition frequency at −20 V/−50 mA; sufficient for PWM frequencies up to ~10 MHz with margin. |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance on standard FR4; informs heatsinking requirements for >150 mW dissipation. |
Pinout & Package
SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, 3-terminal configuration with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires series resistor to limit IB ≤ −200 mA peak per absolute max rating. |
| 2 | Emitter (E) | Common reference terminal for PNP operation; connected to higher potential rail in high-side switch configurations. |
| 3 | Collector (C) | Output current path; sinks load current to ground or lower-potential node when saturated. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested for automotive temperature cycling (−55 °C to +150 °C), humidity, and mechanical shock - suitable for under-hood ECUs without additional qualification. |
| Low VCEsat at high IC | VCEsat ≤ −1.3 V at −150 mA/−15 mA ensures <195 mW conduction loss, reducing thermal stress in space-constrained modules. |
| High fT | 200 MHz transition frequency supports fast edge rates (tr ≤ 30 ns) for PWM dimming and digital signal buffering. |
| Robust ESD rating | HBM Class 2 (≥2 kV) per JESD22-A114 - withstands handling and board assembly without external protection diodes. |
Applications
| Automotive Door Module Switching | LED Tail Light Bias Control |
|---|---|
Use Scenario: Driving resistive loads such as window motor relays and door lock solenoids in 12 V/48 V architectures. IC Role / Device Role / Timing Role: PNP high-side switch controlling load current path between battery rail and ground-return path. Use Value: −60 V VCEO accommodates load dump transients; AEC-Q101 qualification ensures reliability over 15-year vehicle lifetime. |
Use Scenario: Providing stable bias current to high-brightness LED strings in rear lighting clusters. IC Role / Device Role / Timing Role: Linear current source configured with emitter resistor for constant-current LED drive. Use Value: Tight hFE spread (100–300) enables consistent current matching across production batches without trimming. |
| Industrial Sensor Signal Conditioning | Power Supply Enable Sequencing |
Use Scenario: Amplifying low-level analog signals from NTC thermistors or Hall-effect sensors in PLC I/O modules. IC Role / Device Role / Timing Role: Discrete common-emitter amplifier stage with fixed-gain bias network. Use Value: fT = 200 MHz and low Cc = 8 pF preserve signal integrity up to 100 kHz bandwidth with minimal phase shift. |
Use Scenario: Enabling/disabling downstream DC-DC converters during system power-up and fault recovery sequences. IC Role / Device Role / Timing Role: Logic-level controlled enable switch interfacing microcontroller GPIO to PMIC EN pins. Use Value: toff ≤ 365 ns ensures sub-microsecond disable timing, critical for fault containment in multi-rail supplies. |
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 (ON Semiconductor) | Same SOT23 pinout and −60 V/−600 mA ratings, but not AEC-Q101 qualified; hFE min = 100 at −10 mA only. | Limited to non-automotive industrial or consumer use; lacks automotive temperature cycling validation. | Select when cost sensitivity outweighs automotive qualification requirements and operating ambient stays below 105 °C. |
| PN2907A (Central Semiconductor) | Through-hole TO-92 package; identical electrical specs but Rth(j-a) ≈ 200 K/W; no AEC-Q101 certification. | Used where manual assembly or prototyping dominates; incompatible with automated SMT lines requiring SOT23 footprint. | Choose for breadboard validation or legacy through-hole designs where thermal margin exceeds 500 K/W requirement. |

FAQ
Is PMBT2907A-QR pin-compatible with PMBT2222A-Q?
No - PMBT2907A-QR is a PNP transistor with Base-Emitter-Collector pinout (1-2-3), while PMBT2222A-Q is its NPN complement with Emitter-Base-Collector pinout (1-2-3). They share the same SOT23 package and footprint but require reversed PCB layout and biasing polarity for functional pairing.
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is −200 mA (single pulse, tp ≤ 1 ms). For continuous DC operation, base current must be limited to ensure junction temperature remains ≤150 °C - typically ≤−50 mA with adequate PCB copper area, based on Rth(j-a) = 500 K/W and Ptot = 250 mW at 25 °C ambient.
Does PMBT2907A-QR support operation at −40 °C ambient?
Yes - the device is fully specified from −65 °C to +150 °C ambient, with hFE, VCEsat, and switching times characterized down to −55 °C. At −40 °C, hFE remains ≥100 and VCEsat decreases slightly, improving conduction efficiency in cold-start automotive conditions.
Can PMBT2907A-QR replace BC807-40 in existing designs?
Only with layout and bias verification - both are SOT23 PNP transistors, but BC807-40 has hFE = 250–600 and VCEsat ≤ −0.7 V at −100 mA, whereas PMBT2907A-QR offers lower hFE and higher VCEsat. Replacing it may require recalculating base drive and verifying thermal margin due to 2.3× higher Rth(j-a).
