Product details
Overview
MMDT2222A-7-F from Diodes Incorporated is a dual NPN small-signal transistor in SOT363 package, rated for 40 V VCEO, 600 mA IC, and 200 mW power dissipation. It delivers hFE = 35–300 across 100 µA–500 mA collector current, with fT = 300 MHz and VCE(SAT) ≤ 1.0 V at 500 mA/50 mA drive - used in automotive lighting control, sensor interface amplification, and medium-power switching in space-constrained PCBs.
For engineers reviewing the MMDT2222A-7-F datasheet, MMDT2222A-7-F pinout, MMDT2222A-7-F application, or MMDT2222A-7-F equivalent, key selection criteria include dual-NPN matching tolerance, AEC-Q101 qualification, SOT363 thermal resistance (625 °C/W), and guaranteed BVCEO ≥ 40 V under pulsed conditions.
Technical Context
This dual NPN transistor uses epitaxial planar die construction to ensure consistent gain matching and low leakage (ICBO ≤ 10 nA at 60 V). Its ultra-small SOT363 footprint supports high-density routing while maintaining thermal performance via 1 oz copper pad layout per JEDEC standards.
The device operates across –55 °C to +150 °C and meets AEC-Q101 stress testing for automotive reliability. Switching parameters - tD ≤ 10 ns, tR ≤ 25 ns, tS ≤ 225 ns - are specified at VCC = 30 V, IC = 150 mA, enabling fast digital logic interfacing and PWM-driven load control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IC (max) | 600 mA - Continuous collector current rating; supports driving relays, LEDs, or small solenoids directly. |
| PD | 200 mW - Power dissipation limit on FR-4 PCB with minimum recommended copper; defines thermal headroom in compact layouts. |
| hFE | 35–300 - DC current gain range across 100 µA–500 mA; allows flexible bias design for analog amplification or saturated switching. |
| fT | 300 MHz - Current gain-bandwidth product; supports RF preamplifier stages up to VHF band in low-noise receivers. |
| ESD HBM | ≥ 4,000 V - Human Body Model rating; ensures robustness during manual handling and board assembly without extra protection. |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic case (2.15 mm × 2.10 mm × 1.00 mm), halogen- and antimony-free, matte tin terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter 1) | Emitting terminal of first NPN transistor | Common reference node for Q1; tied to ground or local emitter resistor in amplifier configurations. |
| 2 (Base 1) | Control input for first NPN transistor | Receives base drive current to switch or amplify; requires current-limiting resistor when driven from MCU GPIO. |
| 3 (Collector 1) | Output terminal of first NPN transistor | Connects to load (e.g., LED anode or relay coil); pulled high through pull-up or supply rail in open-collector mode. |
| 4 (Emitter 2) | Emitting terminal of second NPN transistor | Independent emitter node for Q2; enables dual-channel operation without shared emitter constraints. |
| 5 (Base 2) | Control input for second NPN transistor | Separate control path for independent switching or differential pair biasing; matches Q1 electrical characteristics. |
| 6 (Collector 2) | Output terminal of second NPN transistor | Second switched output; supports redundant signaling, push-pull drivers, or mirrored current sources. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3022LW-7 | Higher VCEO = 50 V, lower hFE min = 20, same SOT363 package | Better suited for 48 V industrial bus interfaces where higher breakdown margin is required | Select when operating above 40 V or needing tighter thermal derating at elevated ambient temperatures |
| BC847BDW1T1G | Lower VCEO = 45 V, hFE = 200–450, but not AEC-Q101 qualified | Cost-optimized for consumer-grade portable electronics without automotive qualification needs | Choose for non-automotive designs where qualification overhead is unnecessary and higher gain is prioritized |
Compared with DMT3022LW-7 and BC847BDW1T1G, MMDT2222A-7-F uniquely balances AEC-Q101 compliance, 40 V robustness, and dual-transistor integration - making it optimal for space-limited automotive subsystems requiring production-grade reliability.

FAQ
Is MMDT2222A-7-F pin-compatible with single-transistor SOT23 packages?
No - MMDT2222A-7-F uses a 6-pin SOT363 package with dual NPN configuration, whereas standard SOT23 transistors have only 3 pins. Direct replacement requires PCB layout revision to accommodate the different pin count and internal dual topology.
What is the maximum junction temperature during continuous operation?
The absolute maximum junction temperature is +150 °C. At 25 °C ambient and 200 mW dissipation, junction temperature rises by 125 °C (625 °C/W × 0.2 W), reaching 150 °C - confirming operation at full power is only viable with zero ambient rise or active cooling.
Does MMDT2222A-7-F support linear (analog) amplification modes?
Yes - its hFE specification covers 100 µA to 500 mA, and typical fT = 300 MHz supports stable small-signal amplification up to ~10 MHz. Designers must ensure proper emitter degeneration and thermal stabilization for bias point stability.
How does the "K1P" marking relate to the MMDT2222A-7-F part number?
"K1P" is the top-side product type marking code laser-etched on the SOT363 package. It uniquely identifies the MMDT2222A die variant and is used for traceability and counterfeit detection - matching the -7-F tape-and-reel ordering code per Diodes' packaging documentation.
