Product details
Overview
2PB709AQ,115 from Nexperia is a PNP general purpose bipolar junction transistor in SC-59 (SOT346) package, rated for −45 V VCEO, −100 mA IC, and 250 mW Ptot, with DC current gain hFE of 160–260 at IC = −2 mA and VCE = −10 V. It serves as a low-voltage, low-current switching or amplification device in discrete logic interfaces and signal conditioning circuits.
For engineers reviewing the 2PB709AQ,115 datasheet, 2PB709AQ,115 pinout, 2PB709AQ,115 application, or 2PB709AQ,115 equivalent, key selection considerations include its PNP polarity, SC-59 thermal resistance (500 K/W), VCEsat ≤ −500 mV at IC = −100 mA/IB = −10 mA, fT = 60 MHz, and complementarity to NPN 2PB601A.
Technical Context
This PNP BJT operates in active or saturation mode for linear amplification or digital switching. Its design supports low-power, low-frequency signal control with verified cutoff currents (ICBO ≤ −10 nA at Tj = 25 °C) and stable gain across temperature.
The device uses silicon planar epitaxial construction, mounted on FR4 PCB per IEC 134 limiting values, with thermal resistance Rth j-a = 500 K/W defining its power derating envelope up to Tamb = +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - maximum safe collector-emitter voltage under open-base condition; defines off-state blocking capability |
| IC (DC) | −100 mA - continuous collector current limit; sets max load drive capacity in switching applications |
| hFE | 160–260 - DC current gain at IC = −2 mA/VCE = −10 V; determines base drive requirements for saturation |
| VCEsat | ≤ −500 mV - collector-emitter saturation voltage at IC = −100 mA/IB = −10 mA; impacts conduction loss and logic-level compatibility |
| fT | 60 MHz - transition frequency at IC = −1 mA/VCE = −10 V; indicates usable bandwidth for small-signal amplification |
| Ptot | 250 mW - total power dissipation at Tamb ≤ 25 °C; defines thermal headroom before derating begins |
| Rth j-a | 500 K/W - junction-to-ambient thermal resistance on FR4 board; governs temperature rise under load |
Pinout & Package
2PB709AQ,115 is housed in SC-59 (SOT346), a plastic surface-mounted package with 3 leads and dimensions per IEC/JEDEC standards (D = 3.1 mm, E = 2.7 mm, Lp = 1.3 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal; reverse-biased to turn on PNP device; requires current sink for activation |
| 2 | Emiter | Current source terminal; connected to higher potential rail in typical common-emitter switch configuration |
| 3 | Collector | Current sink terminal; delivers load current to ground or lower-potential node when saturated |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage PNP operation | Rated for −45 V VCEO; suitable for 3.3 V/5 V logic-level interface and battery-powered systems |
| Controlled DC current gain | hFE = 160–260 ensures predictable base drive sizing without overdesign or marginal biasing |
| Low saturation voltage | VCEsat ≤ −500 mV minimizes power loss and enables clean TTL/CMOS-compatible output levels |
| SC-59 package thermal performance | Rth j-a = 500 K/W on FR4 allows reliable operation up to +150 °C ambient with no heatsink |
Applications
| LED Driver Circuit | Level-Shifting Interface |
|---|---|
Use Scenario: Driving low-current indicator LEDs from microcontroller GPIO pins operating at 3.3 V or 5 V. IC Role / Device Role / Timing Role: PNP switch controlling LED anode connection to supply rail; emitter-follower or common-emitter topology. Use Value: Low VCEsat ensures minimal voltage drop across transistor, preserving forward voltage margin for red/green/yellow LEDs. | Use Scenario: Translating logic-high signals from a 5 V MCU to a 12 V peripheral input requiring active-low enable. IC Role / Device Role / Timing Role: Inverting level shifter with PNP pull-up; base driven by MCU output, collector tied to 12 V via load resistor. Use Value: Verified hFE range enables robust drive with standard 10 kΩ base resistor; fT > 60 MHz supports fast edge transitions. |
| Discrete Logic Inverter | Low-Power Sensor Signal Amplifier |
Use Scenario: Constructing non-inverting or inverting gates in legacy analog-digital hybrid systems where IC logic is unavailable or undesirable. IC Role / Device Role / Timing Role: Common-emitter amplifier configured as digital inverter; biased into saturation/cutoff by resistor network. Use Value: Tight VCEO/VCB ratings prevent breakdown during rail transients; low ICBO (< −10 nA) maintains high off-state impedance. | Use Scenario: Amplifying weak DC-coupled sensor outputs (e.g., thermistor divider, photodiode current) in portable instrumentation. IC Role / Device Role / Timing Role: Single-stage common-emitter amplifier with emitter degeneration for linearity and stability. Use Value: Stable hFE across temperature and low noise characteristics support accurate low-level analog gain without added complexity. |
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 |
|---|---|---|---|
| 2PB709AR,115 | Higher hFE (210–340) and fT (70 MHz); same package, voltage, and current ratings | Better suited for higher-gain amplification or faster switching where tighter base drive control is needed | Select 2PB709AR,115 when gain consistency or bandwidth exceeds requirements of 2PB709AQ,115 |
| MMBT3906LT1G | SOT-23 package; hFE = 100–300; VCEO = −40 V; Ptot = 310 mW; slightly higher power rating but lower voltage margin | Compatible in low-voltage logic switching but not direct replacement due to different pinout and package footprint | Choose MMBT3906LT1G only if SOT-23 layout is fixed and −40 V rating suffices for system rail conditions |
Compared with 2PB709AR,115 and MMBT3906LT1G, the 2PB709AQ,115 offers the lowest hFE and fT in its family-ideal for cost-sensitive, moderate-speed switching where predictable, conservative gain simplifies bias design and reduces risk of unintended oscillation.

FAQ
What is the pin configuration of the 2PB709AQ,115?
The 2PB709AQ,115 uses SC-59 (SOT346) package with pin 1 = Base, pin 2 = Emitter, and pin 3 = Collector, as confirmed in the official Nexperia data sheet. This pinout is standardized across the 2PB709A series and differs from SOT-23 or TO-92 layouts. Always verify orientation using the marking code "BQ" and top-view diagram before PCB layout.
What is the maximum collector-emitter voltage rating for the 2PB709AQ,115?
The 2PB709AQ,115 has a maximum collector-emitter voltage (VCEO) rating of −45 V under open-base conditions, per IEC 134 Absolute Maximum Ratings. This rating applies at Tamb ≤ 25 °C and must be derated linearly above that temperature using the specified thermal resistance of 500 K/W.
Does the 2PB709AQ,115 have a documented NPN complement?
Yes-the NPN complement to the 2PB709AQ,115 is the 2PB601A, explicitly stated in the Nexperia data sheet. Both share matching voltage, current, and package specifications, enabling balanced design of push-pull or complementary switching stages in discrete analog and power control circuits.
What is the DC current gain (hFE) range for the 2PB709AQ,115?
The 2PB709AQ,115 exhibits a DC current gain (hFE) range of 160 to 260 when measured at IC = −2 mA and VCE = −10 V, Tamb = 25 °C. This gain band is binned and marked as "BQ"; other variants (e.g., BR, BS) offer higher hFE ranges but identical package and absolute ratings.
Can the 2PB709AQ,115 be used in automotive applications?
The 2PB709AQ,115 is not qualified to AEC-Q101 or automotive-grade reliability standards. While it operates across −65 °C to +150 °C ambient and meets industrial thermal limits, Nexperia documentation explicitly excludes medical, military, aircraft, space, and life-support use-and does not list automotive qualification for this part. For automotive designs, consult Nexperia's AEC-Q101-certified PNP transistors instead of the 2PB709AQ,115.
