Product details
Overview
MMBT2222A-7-F from Diodes Incorporated is a 40V NPN small-signal transistor in SOT23 package, rated for 600mA continuous collector current and 310mW power dissipation at 25°C ambient. It delivers low VCE(sat) of ≤300mV at 150mA/15mA drive and DC current gain (hFE) from 35 to 300 across 100µA–500mA, enabling reliable low-power switching and amplification in compact PCB layouts.
For engineers reviewing the MMBT2222A-7-F datasheet, MMBT2222A-7-F pinout, MMBT2222A-7-F application, or MMBT2222A-7-F equivalent, key selection criteria include saturation voltage under defined IC/IB, thermal resistance (RθJA = 403°C/W), ESD robustness (HBM 4kV), and SOT23 mechanical compatibility with automated assembly.
Technical Context
This NPN bipolar junction transistor uses epitaxial planar die construction for stable gain and low leakage. Its VCEO = 40V and VCBO = 75V support operation in low-voltage logic interface and signal conditioning circuits where moderate breakdown margin is required.
Switching performance is characterized by td ≤10ns, tr ≤25ns, ts ≤225ns, and tf ≤60ns at 30V VCC and 150mA IC, while fT ≥300MHz ensures suitability for RF preamplifier stages up to ~100MHz with proper biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage before avalanche conduction in common-emitter configuration. |
| IC (continuous) | 600 mA - Continuous collector current limit defining maximum linear or switching load capability at 25°C ambient. |
| VCE(sat) | ≤300 mV @ 150mA/15mA - Ensures minimal voltage drop and power loss when used as a saturated switch in digital logic or driver stages. |
| hFE | 35–300 - Wide DC current gain range supports flexible bias design across operating currents from µA to 500mA. |
| fT | ≥300 MHz - Enables use in high-frequency small-signal amplification up to UHF band with appropriate matching networks. |
| RθJA | 403 °C/W - Thermal resistance defines junction-to-ambient temperature rise per watt; requires minimum copper pad area for safe 310mW operation. |
| ESD HBM | 4,000 V - Robust electrostatic discharge immunity reduces handling sensitivity during SMT assembly and board-level testing. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3-pin configuration, 0.008g mass, UL 94V-0 flammability rating, and matte tin terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emission terminal for majority carriers | Reference node for base-emitter bias; connects to ground or low-impedance return path in common-emitter configurations. |
| 2 (Base) | Control electrode for carrier injection | Receives current-limited drive signal; requires series resistor to limit IB and ensure predictable saturation or linear operation. |
| 3 (Collector) | Current collection terminal | Connects to load or supply rail; carries full IC; must be routed with adequate trace width for 600mA continuous current. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | ≤300mV at 150mA/15mA enables efficient switching in battery-powered logic interfaces and LED drivers. |
| High fT | ≥300MHz supports RF amplifier designs up to 100MHz without external neutralization or compensation. |
| Wide hFE range | 35–300 across 100µA–500mA allows single-part reuse in both micro-power sensor interfaces and higher-current driver stages. |
| Automotive-grade variant available | MMBT2222AQ meets AEC-Q101 requirements, supporting qualification-critical applications without redesign. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) satisfies strict environmental compliance mandates. |
Applications
| LED Driver Stage | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving discrete indicator LEDs or low-current RGB segments from 3.3V/5V MCU outputs. IC Role / Device Role / Timing Role: NPN switch controlling LED anode/cathode current path with TTL/CMOS-compatible base drive. Use Value: VCE(sat) ≤300mV minimizes forward voltage overhead, preserving LED brightness and efficiency at 10–100mA loads. |
Use Scenario: Amplifying weak analog sensor signals (e.g., thermistor, photodiode) before ADC sampling. IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier providing 20–50dB voltage gain with bandwidth >1MHz. Use Value: fT ≥300MHz and hFE ≥100 at 1mA enable stable gain at audio and sub-MHz frequencies without instability. |
| Power Supply Enable Control | Level Translation Interface |
Use Scenario: Enabling/disabling 12V auxiliary rails using 3.3V logic signals in industrial control modules. IC Role / Device Role / Timing Role: High-side or low-side switch controlling PMOS/NMOS gate drive or relay coil current. Use Value: IC = 600mA and VCEO = 40V accommodate typical 12V/24V enable loads with safety margin and fast turn-off (tf ≤60ns). |
Use Scenario: Translating 1.8V logic outputs to 5V input thresholds in mixed-voltage digital systems. IC Role / Device Role / Timing Role: Single-transistor level shifter with emitter-follower or common-base configuration. Use Value: Low VBE(on) (0.6–1.2V) and tight VCE(sat) tolerance ensure clean threshold crossing and minimal propagation delay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN small-signal transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN2222A (ON Semiconductor) | SOT23 package; VCEO = 40V, IC = 600mA, but VCE(sat) = 0.3V @ 150mA/15mA - identical saturation spec; fT = 250MHz (lower than MMBT2222A's 300MHz). | Lower fT limits use in higher-frequency amplifiers; otherwise interchangeable in DC/low-speed switching. | Select PN2222A only when fT > 250MHz is not required and second-source qualification is mandated. |
| BC847B (Nexperia) | SOT23; VCEO = 45V, IC = 100mA (significantly lower); hFE = 200–450 at 2mA, but derates sharply above 50mA. | Not suitable for >100mA loads; intended for signal amplification only, not power switching. | Choose BC847B only for low-current analog gain stages where IC ≤50mA and higher hFE consistency is prioritized over current capacity. |
Compared with PN2222A and BC847B, MMBT2222A-7-F uniquely balances 600mA current handling, 300MHz fT, and ≤300mV saturation in a single SOT23 device-making it optimal for mixed-signal designs requiring both switching headroom and RF-capable gain.

FAQ
What is the maximum allowable junction temperature for MMBT2222A-7-F?
The absolute maximum operating junction temperature is +150°C, with storage temperature spanning −55°C to +150°C. Derating begins at +25°C ambient: power dissipation must be reduced linearly to zero at +150°C case temperature, based on RθJA = 403°C/W for standard PCB layout.
Is MMBT2222A-7-F suitable for automotive applications?
The standard MMBT2222A-7-F is not AEC-Q101 qualified. However, Diodes offers the MMBT2222AQ variant-identical in electrical specs and SOT23 packaging-with full automotive qualification, including temperature cycling, humidity testing, and failure analysis per AEC standards.
How does the SOT23 package affect thermal performance?
The SOT23 package has RθJA = 403°C/W on minimal FR-4 copper and 357°C/W on 15mm × 15mm 1oz copper. Effective heat dissipation requires adherence to Diodes' recommended pad layout (2.0mm × 0.8mm thermal pad) and avoidance of enclosed vias that impede convection cooling.
Can MMBT2222A-7-F replace a 2N2222 in existing designs?
Yes-MMBT2222A-7-F matches the 2N2222's VCEO, hFE, and VCE(sat) specifications while offering SOT23 surface-mount compatibility. Pinout differs (SOT23: E-B-C vs. TO-18: E-B-C), so PCB layout must be updated; no circuit revalidation is needed for equivalent biasing and load conditions.
