Product details
Overview
DZT2222A-13 from Diodes Incorporated is a 40V NPN small-signal transistor in SOT223 package, rated for 600mA collector current and 0.83W power dissipation, with VCE(sat) = 0.11V at IC = 150mA/IB = 15mA, and hFE ≥ 100 at IC = 150mA - used in medium-power switching and linear amplification stages of industrial control interfaces and LED driver bias circuits.
For engineers reviewing the DZT2222A-13 datasheet, DZT2222A-13 pinout, DZT2222A-13 application, or DZT2222A-13 equivalent, key selection criteria include verified VCEO = 40V rating, SOT223 thermal resistance (RθJA = 150°C/W), DC current gain stability across -55°C to +150°C, and complementary PNP pairing with DZT2907A-13.
Technical Context
This NPN bipolar junction transistor uses epitaxial planar die construction for consistent gain and breakdown performance. It operates with VBE(sat) ≤ 0.87V at IC = 150mA and delivers fT = 300MHz for high-speed switching applications up to ~100kHz duty-cycled loads.
The device supports automated assembly via SOT223's standardized leadframe geometry and matte tin-plated terminals compliant with MIL-STD-202 solderability. Its safe operating area (SOA) is defined up to 60V/600mA with pulse-width-limited derating above 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum continuous collector-emitter voltage before avalanche breakdown; defines upper rail limit in switch-mode or amplifier stage design. |
| IC | 600 mA - Absolute maximum DC collector current; usable up to 500mA with VCE ≤ 10V and proper heatsinking. |
| VCE(sat) | 0.11 V @ 150mA/15mA - Low saturation voltage minimizes conduction loss in medium-power switching nodes. |
| hFE | 100–300 @ 150mA - High, stable DC current gain enables simple base-drive resistor networks without active feedback. |
| fT | 300 MHz - Transition frequency confirms suitability for fast-switching applications such as PWM dimming control and relay drivers. |
| RθJA | 150 °C/W - Thermal resistance on minimum recommended pad layout; requires PCB copper area planning for >300mW continuous operation. |
| PD | 0.83 W - Maximum steady-state power dissipation at 25°C ambient; derates linearly to zero at 150°C junction temperature. |
Pinout & Package
Package: SOT223 - surface-mount, 4-pin (3 active + 1 thermal tab), molded green plastic housing with UL 94V-0 flammability rating and moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current sink node; connected to ground or low-side return path in common-emitter configurations. |
| 2 (Base) | B | Control input; requires current-limited drive (e.g., 15mA typical) to achieve specified VCE(sat). |
| 3 (Collector) | C | Current source node; connects to load or supply rail; electrically isolated from thermal tab. |
| 4 (Tab / Collector) | C (Thermal) | Exposed metal tab internally tied to collector; provides mechanical mounting and thermal conduction to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Ensures tight parameter distribution (e.g., hFE tolerance ±20%) and repeatable BVCEO > 40V across production lots. |
| Matte tin-plated leads | Guarantees solderability per MIL-STD-202 Method 208, eliminating post-reflow oxidation concerns in high-volume assembly. |
| Lead-free & halogen-free "Green" compliance | Meets RoHS 3 (2015/863/EU), AEC-Q101 readiness, and automotive PPAP capability upon request. |
| SOT223 thermal tab integration | Enables 53°C/W junction-to-case thermal resistance, supporting 0.83W dissipation with minimal external heatsink area. |
Applications
| LED Driver Bias Stage | Industrial Relay Driver |
|---|---|
Use Scenario: Driving base of power Darlington or MOSFET gate in constant-current LED string controllers. IC Role / Device Role / Timing Role: Medium-current NPN switch providing precise current mirroring and fast turn-off via low storage time (ts = 188ns). Use Value: VCE(sat) ≤ 0.31V at 500mA reduces heat generation in compact LED driver PCBs with limited copper area. |
Use Scenario: Controlling 24VDC industrial relays in PLC I/O modules requiring >500mA coil drive. IC Role / Device Role / Timing Role: High-gain (hFE ≥ 100) interface transistor translating microcontroller GPIO to relay coil current. Use Value: Complementary pairing with DZT2907A-13 enables push-pull output stages without external level-shifting components. |
| Linear Voltage Regulator Pass Element | Automotive Sensor Signal Conditioning |
Use Scenario: Series pass transistor in low-dropout linear regulators for 5V/3.3V subsystem rails. IC Role / Device Role / Timing Role: Linear amplifier operating in active region with VBE(sat) = 0.87V defining base drive headroom. Use Value: Stable hFE across -55°C to +150°C ensures predictable regulation loop behavior in under-hood environments. |
Use Scenario: Amplifying low-level analog signals from pressure or temperature sensors in engine control units. IC Role / Device Role / Timing Role: Small-signal amplifier with fT = 300MHz enabling bandwidth >100kHz for transient sensor response capture. Use Value: Cobo = 8pF and Cibo = 25pF minimize capacitive loading on high-impedance sensor outputs. |
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 |
|---|---|---|---|
| ZXTN2012ZTA | VCEO = 60V, IC = 1.5A, SOT89 package, RθJA = 125°C/W | Higher voltage/current rating but larger footprint; not drop-in compatible due to different pinout and thermal tab location. | Select when >40V rail margin or >600mA peak load is required; verify PCB pad redesign for SOT89. |
| MMBT2222ALT1G | VCEO = 40V, IC = 600mA, SOT23 package, RθJA = 310°C/W, lower power handling (0.35W) | Same electrical specs but significantly reduced thermal performance; unsuitable for sustained >200mW operation. | Choose only for space-constrained, low-duty-cycle signal switching where SOT223's thermal advantage is unnecessary. |
Compared with ZXTN2012ZTA and MMBT2222ALT1G, DZT2222A-13 uniquely balances 40V/600mA capability with SOT223's superior thermal management (0.83W vs. 0.35W) and industrial-grade reliability - making it optimal for medium-power, thermally constrained designs where lead-free compliance and AEC-Q101 readiness matter.

FAQ
Is DZT2222A-13 qualified to AEC-Q101?
Yes - DZT2222A-13 is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. Full qualification documentation, including stress test reports and PPAP support, is available upon request through Diodes Incorporated's automotive team or authorized distributors.
What is the maximum continuous power dissipation at 85°C ambient?
At TA = 85°C, the maximum continuous power dissipation is 0.42W, calculated using the derating curve: (150°C − 85°C) × (0.83W / 150°C) = 0.42W. This assumes use of the minimum recommended pad layout on FR4 PCB with still-air conditions.
Can DZT2222A-13 replace MMBT2222A in existing SOT23 designs?
No - DZT2222A-13 uses SOT223, which has different footprint, pinout, and thermal tab connection. Direct replacement requires PCB redesign. For SOT23 compatibility, use MMBT2222ALT1G or PZT2222A (SOT223 variant with same pinout but different marking).
Does the thermal tab require electrical isolation from PCB ground?
Yes - the exposed tab is internally connected to the collector. If the collector node is not at ground potential, the tab must be electrically isolated using non-conductive thermal pads or insulated mounting hardware to prevent short circuits on grounded copper pours.
