Product details
Overview
MMDT2222V-7 from Diodes Incorporated is a dual NPN small-signal transistor in SOT563 package, rated for 40 V VCEO, 600 mA IC, and 150 mW power dissipation, with hFE ranging from 35 to 300 across 100 µA–500 mA collector currents; used in medium-power amplification and switching circuits in automotive infotainment power stages and industrial sensor interface modules.
For engineers reviewing the MMDT2222V-7 datasheet, MMDT2222V-7 pinout, MMDT2222V-7 application, or MMDT2222V-7 equivalent, key selection criteria include VCEO ≥ 40 V, fT = 300 MHz, AEC-Q101 qualification, SOT563 footprint compatibility, and complementary pairing with MMDT2907V for push-pull configurations.
Technical Context
This dual NPN transistor uses epitaxial planar die construction for stable gain and low leakage, supporting both linear amplification (hFE = 40–100 at IC = 1–150 mA) and saturated switching (VCE(sat) ≤ 0.3 V at IC = 150 mA / IB = 15 mA). It operates across –55°C to +150°C and meets AEC-Q101 stress testing for automotive reliability.
Its ultra-small SOT563 package integrates two independent NPN transistors sharing no internal connection, with isolated terminals enabling discrete biasing per device; thermal resistance RθJA = 833°C/W on minimal FR4 copper layout supports moderate-duty cycling without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage before breakdown under open-base conditions |
| IC | 600 mA - Continuous DC collector current handling capacity per transistor element |
| PD | 150 mW - Max steady-state power dissipation on standard FR4 PCB with 1 oz copper |
| fT | 300 MHz - Transition frequency defining usable bandwidth for small-signal amplification |
| hFE | 35–300 - DC current gain range across 100 µA–500 mA IC, enabling wide dynamic bias design |
| VCE(sat) | ≤ 0.3 V @ IC=150 mA/IB=15 mA - Low saturation voltage ensures < 45 mW conduction loss in switching mode |
| ESD HBM | 4000 V - Robustness against human-body electrostatic discharge during board assembly |
Pinout & Package
Package: SOT563 - ultra-small surface-mount plastic package (2.2 mm × 1.7 mm × 0.5 mm), molded with halogen/antimony-free "Green" compound, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of Transistor 1 | Low-impedance current sink node; tied to ground or emitter resistor in common-emitter configuration |
| 2 | Base of Transistor 1 | Control input requiring ~0.7 V forward bias and µA-level drive current |
| 3 | Collector of Transistor 1 | High-side output node; connects to load or pull-up resistor in switching or amplification |
| 4 | Emitter of Transistor 2 | Independent emitter terminal; enables separate biasing from Transistor 1 |
| 5 | Base of Transistor 2 | Second control input; electrically isolated from Pin 2 for dual-channel operation |
| 6 | Collector of Transistor 2 | Second high-side output; supports independent load switching or differential pair implementation |
Key Features
| Feature | Design Value |

| SOT563 footprint | Reduces PCB area by >60% vs. SO-8 while maintaining solderability and thermal performance |
Applications
| Automotive Door Module Driver | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving resistive loads such as window motor relays and LED status indicators in door control units. IC Role / Device Role / Timing Role: Dual NPN switch providing independent ON/OFF control of two 24 V loads with fast turn-on (tr ≤ 25 ns) and low saturation loss. Use Value: Enables compact dual-load control using single SOT563 footprint, reducing BOM count and PCB real estate versus discrete SOT23 solutions. | Use Scenario: Amplifying low-level analog outputs from temperature or pressure sensors before ADC sampling. IC Role / Device Role / Timing Role: Medium-gain (hFE = 75 @ IC = 10 mA), low-noise (NF ≤ 4.0 dB) NPN amplifier stage operating at 100 µA–1 mA bias. Use Value: Delivers stable gain over –40°C to +125°C ambient without external compensation, meeting industrial sensor accuracy requirements. |
| USB-C Power Delivery Interface | Smart Lighting Dimming Circuit |
Use Scenario: Level-shifting and enable control for USB-C port power path management ICs. IC Role / Device Role / Timing Role: Logic-level translator and gate driver for 5 V/3.3 V interface signals with ESD-hardened inputs (HBM = 4 kV). Use Value: Eliminates need for dedicated level translators; dual configuration allows simultaneous control of VBUS and CC line switches. | Use Scenario: PWM-controlled current regulation for multi-zone LED arrays in architectural lighting systems. IC Role / Device Role / Timing Role: High-speed (tf ≤ 60 ns) switching element modulating constant-current LED drivers at 1–10 kHz. Use Value: Supports flicker-free dimming with minimal thermal rise due to low VCE(sat) and 150 mW rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2026LSD-13 | Single N-channel MOSFET (20 V, 3.2 A), not bipolar; gate-driven, no base current required | Higher current capability but lacks linear amplification mode and lower VGS(th) tolerance | Select when switching-only operation and >1 A load current are required; not suitable for analog gain stages |
| MMDT3904V-7 | Same SOT563 package, dual NPN, but lower VCEO = 40 V (same), hFE = 100–300 (narrower min), fT = 300 MHz (identical) | Optimized for higher-gain, lower-noise small-signal use; less suited for 500 mA switching | Prefer for RF amplification or low-current bias networks; retain MMDT2222V-7 for mixed-signal or higher-IC switching |
Compared with DMN2026LSD-13 and MMDT3904V-7, MMDT2222V-7 uniquely balances medium-power switching (600 mA), linear amplification (hFE down to 35), and AEC-Q101 qualification-making it optimal for automotive and industrial dual-role circuits where bipolar behavior and reliability are essential.

FAQ
Is MMDT2222V-7 pin-compatible with MMDT3904V-7?
Yes-both use identical SOT563 pinout (Emitter1/Base1/Collector1/Emitter2/Base2/Collector2), allowing direct PCB footprint reuse. However, MMDT2222V-7 offers wider hFE range (35–300 vs. 100–300) and higher IC capability (600 mA vs. 200 mA), making it more suitable for higher-current switching tasks.
What is the maximum junction temperature during continuous operation?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation across –55°C to +150°C ambient. At full 150 mW dissipation on a standard FR4 board, junction temperature rise is approximately 125°C above ambient, so derating is required above +25°C ambient to stay within limit.
Does MMDT2222V-7 support linear amplification at low collector currents?
Yes-hFE is specified at 35 minimum at IC = 100 µA and VCE = 10 V, confirming usable gain in micro-power analog stages. Its NF ≤ 4.0 dB at 100 µA also supports low-noise pre-amplifier designs in sensor front-ends.
Can MMDT2222V-7 replace a single SOT23-3 NPN transistor in existing designs?
No-it contains two independent NPN transistors in one SOT563 package with six terminals, not three. Direct replacement requires circuit redesign to utilize both devices or leave unused pins unconnected; it cannot serve as a drop-in substitute for single-transistor footprints without layout changes.
