Product details
Overview
PMBT2222AQAZ from Nexperia is an NPN bipolar junction transistor optimized for low-voltage switching in space-constrained portable electronics, with 40 V VCEO, 600 mA IC, and DC current gain (hFE) of 100–300 at IC = 150 mA. It operates in DFN1010D-3 (SOT1215) package with 0.37 mm height and visible side pads for AOI-compatible solder joint inspection.
For engineers reviewing the PMBT2222AQAZ datasheet, PMBT2222AQAZ pinout, PMBT2222AQAZ application, or PMBT2222AQAZ equivalent, key selection criteria include its ultra-thin 0.37 mm profile, 800 mA peak collector current capability, 340 MHz fT, low VCEsat of 0.6–1.2 V at IC/IB = 10, and thermal resistance as low as 133 K/W on 4-layer PCBs.
Technical Context
This NPN transistor supports fast switching with ton ≤ 35 ns and toff ≤ 260 ns under defined test conditions (IBon/IBoff = ±15 mA), enabling efficient digital logic-level interfacing and load control. Its base-emitter saturation voltage remains ≤ 2 V at IC = 500 mA, ensuring reliable drive with standard CMOS/TTL outputs.
The device features a thermally enhanced DFN1010D-3 package with dual collector terminals (pins 3 and 4), enabling higher power dissipation up to 940 mW on 4-layer FR4 PCBs with 1 cm² copper pad. Junction temperature is rated to 150 °C, supporting operation in mobile and industrial ambient ranges (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V and lower rail systems. |
| IC | 600 mA continuous - Sustained load switching capacity without derating at Tamb ≤ 25 °C on standard FR4. |
| hFE | 100–300 at VCE = 10 V, IC = 150 mA - Predictable current amplification for stable bias design in linear and switching modes. |
| fT | 340 MHz - Supports high-speed digital switching up to ~100 MHz square-wave operation with minimal delay. |
| VCEsat | 0.6–1.2 V at IC/IB = 10 - Low saturation voltage reduces conduction loss and self-heating in battery-powered loads. |
| Rth(j-a) | 133 K/W on 4-layer FR4 with 1 cm² collector pad - Enables 940 mW power handling without active cooling in compact layouts. |
Pinout & Package
DFN1010D-3 (SOT1215) is a leadless, thermally enhanced surface-mount package measuring 1.1 mm × 1.0 mm × 0.37 mm, with visible and solderable side pads for automated optical inspection (AOI). The package integrates two collector terminals (pins 3 and 4) to improve thermal and current-carrying performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input node; requires ≥13 mA base drive for full saturation at 500 mA collector current. |
| 2 | Emitter (E) | Current return path; tied to ground or low-side reference in common-emitter configurations. |
| 3 & 4 | Collector (C) | Dual collector terminals electrically connected internally; both must be soldered to maximize thermal dissipation and current capacity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-thin profile | 0.37 mm body height - Enables stacking in ultra-slim handheld devices and wearables where Z-height is constrained. |
| AOI-compatible side pads | Visible and solderable terminations on all three sides - Allows automated optical inspection of solder joints without X-ray. |
| Thermally enhanced layout | Dual collector terminals with internal connection - Reduces thermal resistance by up to 30% vs. single-terminal equivalents on same PCB stackup. |
| Pulsed current capability | 800 mA ICM (tp ≤ 1 ms) - Supports short-duration surge loads such as LED flash drivers or relay coil energization. |
Applications
| Smartphone Power Management | Wireless Earbud Charging Control |
|---|---|
Use Scenario: Switching power path between USB-C input and battery during charging in compact smartphone PMIC subsystems. IC Role / Device Role / Timing Role: Low-side NPN switch controlling enable signal to buck converter or load switch IC. Use Value: 0.37 mm height avoids interference with stacked camera modules; 600 mA rating handles typical 500 mA charging enable currents. |
Use Scenario: Enabling/disabling charging circuitry in true wireless stereo (TWS) earbuds with strict board area limits. IC Role / Device Role / Timing Role: Digital on/off switch for charging FET gate drive or battery protection IC enable line. Use Value: Dual collector pads ensure reliable thermal performance in 10 mm × 10 mm earbud PCBs with limited copper area. |
| IoT Sensor Node Wake-Up Circuit | Portable Medical Monitor LED Driver |
Use Scenario: Waking up microcontroller or radio transceiver from deep sleep using external interrupt-triggered transistor switch. IC Role / Device Role / Timing Role: Fast-turn-on NPN switch translating GPIO wake signal into clean 3.3 V/5 V logic-level pulse. Use Value: 35 ns ton and 260 ns toff ensure sub-microsecond response; low IBOFF minimizes leakage in sleep state. |
Use Scenario: Driving indicator LEDs in handheld blood glucose meters or pulse oximeters requiring consistent brightness. IC Role / Device Role / Timing Role: Constant-current switch regulating LED current via emitter resistor feedback. Use Value: Tight hFE spread (100–300) enables predictable current setting; 40 V VCEO accommodates 3.7 V Li-ion + headroom. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PMBT2222AQA | Same die, identical DFN1010D-3 package and marking - direct variant with Z suffix indicating tape-and-reel packaging per AEC-Q200-compliant process flow. | No functional difference; Z-suffix denotes logistics format only - not a performance or reliability upgrade. | Select PMBT2222AQAZ when sourcing requires AEC-Q200-aligned traceability and reel packaging for automated assembly. |
| BC846BW | SOT323 package (2.1 mm × 1.25 mm × 0.95 mm); 65 V VCEO, 100 mA IC, hFE = 110–220 - physically larger and lower current capacity. | Not suitable for 600 mA loads; used in general-purpose signal switching where size and thermal constraints are less severe. | Choose BC846BW only if board layout allows larger footprint and application current stays below 100 mA. |
Compared with PMBT2222AQAZ, the PMBT2222AQA offers identical electrical and thermal performance but lacks Z-suffix traceability; BC846BW trades current capacity and thinness for wider availability in legacy footprints - making PMBT2222AQAZ optimal for next-gen miniaturized designs demanding 600 mA in <1 mm² area.

FAQ
What is the maximum allowable junction temperature for PMBT2222AQAZ?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this limit risks permanent degradation of hFE and increased leakage. Derating is required above 25 °C ambient - for example, maximum continuous IC drops to ~420 mA at Tamb = 85 °C on standard FR4.
Can PMBT2222AQAZ replace the legacy PNP PMBT2907AQA in the same circuit?
No - PMBT2222AQAZ is an NPN transistor and cannot directly substitute the PNP PMBT2907AQA due to opposite polarity and complementary biasing requirements. Swapping would invert logic states and likely cause circuit failure unless topology is redesigned for NPN-based high-side or low-side switching.
Is the DFN1010D-3 package compatible with standard reflow profiles for lead-free soldering?
Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D reflow profiles for lead-free processes. Peak temperature must not exceed 260 °C, with time above 217 °C limited to 60–150 seconds. Figure 16 in the datasheet provides exact solder land dimensions and stencil recommendations for void-free joints.
Does PMBT2222AQAZ support pulsed operation beyond its DC current rating?
Yes - it supports 800 mA peak collector current (ICM) for single pulses ≤ 1 ms with duty cycle ≤ 0.02. This enables brief high-current events like LED strobing or solenoid actuation without exceeding thermal limits, provided average power remains within Ptot derating curves for the PCB layout used.
