Product details
Overview
2PA1774QMB from Nexperia is a PNP general-purpose transistor in a leadless DFN1006B-3 (SOT883B) package, rated for −40 V VCEO, −100 mA IC, and DC current gain (hFE) of 120–270 at VCE = −6 V and IC = −1 mA; used for low-power switching and amplification in space-constrained mobile PCBs.
For engineers reviewing the 2PA1774QMB datasheet, 2PA1774QMB pinout, 2PA1774QMB application, or 2PA1774QMB equivalent, key selection criteria include ultra-small footprint (1.0 × 0.6 × 0.37 mm), AEC-Q101 qualification, thermal resistance of 500 K/W (free air), and binary marking code "0100 0000" for traceability in high-volume SMT assembly.
Technical Context
This PNP bipolar junction transistor operates as a current-controlled switch or linear amplifier with base-emitter saturation voltage below −600 mV at IC = −10 mA and IB = −1 mA, enabling efficient low-voltage biasing in portable systems. Its transition frequency (fT) of 100 MHz supports moderate-speed digital switching up to ~10 MHz with controlled rise/fall times.
The device uses a planar epitaxial process with optimized doping profiles to achieve stable hFE across temperature (−55 °C to +150 °C) and low collector-base leakage (ICBO ≤ −100 nA at VCB = −30 V), critical for battery-powered standby circuits requiring minimal quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V - Maximum safe collector-emitter voltage under open-base condition; defines maximum supply rail compatibility in PNP-switched loads. |
| IC | −100 mA - Continuous collector current rating; supports driving small relays, LEDs, or logic-level translators in handheld devices. |
| hFE | 120–270 - DC current gain range at VCE = −6 V, IC = −1 mA; enables predictable base drive sizing for reliable saturation in switching applications. |
| VCE(sat) | ≤ −200 mV at IC = −50 mA, IB = −5 mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle on-state operation. |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance in free air; informs derating requirements when no PCB copper pour is available. |
| fT | 100 MHz - Transition frequency at VCE = −12 V, IC = −2 mA; indicates usable bandwidth for RF-coupled pre-amplifier stages or fast digital signal inversion. |
| Cc | 2.2 pF - Collector capacitance at VCB = −12 V; limits high-frequency gain roll-off and affects stability in feedback amplifier configurations. |
Pinout & Package
DFN1006B-3 (SOT883B) is a leadless, ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.37 mm with three solderable lands and no leads; designed for reflow-only assembly and compatible with standard 0201 footprint tooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input terminal; requires series resistor to limit IB and ensure hFE-based saturation under worst-case VBE and temperature. |
| 2 | Emitter | Common reference node for PNP operation; connected to higher potential (e.g., VCC); must be routed with low-inductance path for fast switching. |
| 3 | Collector | Output current sink terminal; connects to load; thermal pad under collector land improves heat dissipation when mounted on ≥1 cm² copper area. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables use in infotainment and body control modules without additional qualification. |
| Ultra-low profile (0.37 mm height) | Enables stacking with thin batteries or placement under displays in smartphones and wearables where Z-axis clearance is constrained to <0.4 mm. |
| Power dissipation comparable to SOT23 | Delivers 250 mW at Tamb ≤ 25 °C despite 60% smaller footprint-supports same thermal design margins as legacy SOT23 in miniaturized layouts. |
| Binary top-side marking ("0100 0000") | Enables automated optical inspection (AOI) and traceability in high-speed pick-and-place lines without laser marking or ink degradation risks. |
Applications
| Mobile Power Switching | Low-Voltage Signal Amplification |
|---|---|
Use Scenario: Controlling LED backlight current in OLED display modules powered from 3.3 V rails. IC Role / Device Role / Timing Role: PNP switch sinking current from cathode side, driven by GPIO with 10 kΩ base resistor. Use Value: VCE(sat) ≤ −200 mV ensures >94% efficiency at 20 mA load, minimizing heat buildup behind fragile display glass. |
Use Scenario: Biasing photodiode transimpedance amplifier input stage in ambient light sensor ICs. IC Role / Device Role / Timing Role: Active load transistor providing stable DC bias current to op-amp input node. Use Value: hFE consistency (120–270) across −40 °C to +85 °C maintains calibrated gain accuracy without software compensation. |
| Automotive Door Module Logic | Portable Audio Signal Inversion |
Use Scenario: Driving small solenoids in smart door lock actuators within AEC-Q101-compliant ECUs. IC Role / Device Role / Timing Role: High-side switch controlling 12 V solenoid coil via microcontroller output with level-shifting. Use Value: VCEO = −40 V withstands load-dump transients up to 35 V, eliminating need for external TVS clamping. |
Use Scenario: Inverting audio line-level signals between codec and headphone driver in Bluetooth earbuds. IC Role / Device Role / Timing Role: Class-A common-emitter amplifier stage with fixed emitter degeneration resistor. Use Value: fT = 100 MHz ensures flat frequency response up to 20 kHz with <0.1 dB ripple, preserving audio fidelity. |
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 |
|---|---|---|---|
| 2PC4617QMB | NPN complement with identical package, VCEO = 40 V, IC = 100 mA, hFE = 120–270; polarity reversal required in circuit layout. | Suitable only where NPN topology is preferred (e.g., low-side switching, pull-down logic), not drop-in replacement for PNP biasing networks. | Select only if redesign allows NPN-based topology; verify base drive polarity and signal inversion impact on system timing. |
| BC807-25 | SOT23 package (2.9 × 1.3 × 1.0 mm), same hFE range but 2.7× larger footprint and 2.7× taller; Rth(j-a) = 300 K/W (free air). | Acceptable where board space permits and thermal margin exceeds 500 K/W requirement; not suitable for ultra-thin assemblies. | Choose when existing SOT23 footprints exist and rework cost outweighs size benefit; avoid in new ultra-compact designs targeting <0.4 mm Z-height. |
Compared with 2PC4617QMB and BC807-25, the 2PA1774QMB uniquely delivers PNP functionality in the smallest standardized footprint (DFN1006B-3) with automotive qualification-making it the sole option for AEC-Q101-compliant, space-constrained PNP switching without topology change or board real estate penalty.

FAQ
Is 2PA1774QMB suitable for reflow soldering only?
Yes-Nexperia specifies reflow soldering as the sole recommended method. The DFN1006B-3 package lacks leads and relies on precise thermal profiling (per J-STD-020) to ensure void-free solder joints on all three lands. Hand soldering or wave soldering is not supported and may cause delamination or intermetallic failure.
What does the binary marking "0100 0000" indicate?
This 8-bit code identifies the 2PA1774QMB variant per Nexperia's DFN1006B-3 marking standard: bits 0–3 encode the type number suffix (Q), and bits 4–7 encode the revision or wafer lot group. It enables automated optical verification during SMT line setup and post-assembly traceability audits.
How does its thermal performance compare to SOT23 equivalents?
At 500 K/W (free air), 2PA1774QMB has higher thermal resistance than typical SOT23 transistors (~300 K/W), but its 212 K/W rating on 1 cm² copper matches SOT23 performance. Designers must allocate ≥1 cm² thermal pad under pin 3 (collector) to achieve equivalent power handling (590 mW).
Can it replace BC856 in existing designs?
No-BC856 is a PNP transistor in SOT23 with VCEO = −65 V and hFE = 110–220, but its larger footprint, different pinout (emitter-collector-base vs. base-emitter-collector), and non-AEC-Q101 qualification prevent direct substitution. Layout redesign and thermal validation are required.
