Product details
Overview
ZXTP722MATA from Diodes Incorporated is a 70V PNP low-saturation bipolar junction transistor in a DFN2020B-3 package, rated for -2.5A continuous collector current, -220mV max VCE(sat) at -1A, and qualified to AEC-Q101 for automotive reliability. It serves as a high-current power switch in DC-DC converters and MOSFET gate drivers where low on-resistance (117 mΩ) and thermal efficiency are critical.
For engineers reviewing the ZXTP722MATA datasheet, ZXTP722MATA pinout, ZXTP722MATA application, or ZXTP722MATA equivalent, key selection criteria include its -70V VCEO, RθJA of 51°C/W (on 10 cm² 1oz Cu), AEC-Q101 qualification, and DFN2020B-3 footprint compatibility with space-constrained power stages.
Technical Context
This PNP transistor operates with a maximum collector-emitter breakdown voltage of -70V and supports pulsed peak currents up to -3A. Its hFE is specified from -10mA to -3A, maintaining ≥275 gain at -3A, enabling stable current amplification across wide load ranges.
VCE(sat) remains ≤ -220mV at -1A/−100mA drive, and its 0.6mm profile with exposed collector pad delivers 60% lower RθJA than SOT-23 under identical PCB conditions - critical for thermally dense motor control and charging circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -70 V - Withstands reverse-biased collector-emitter voltage up to 70V in switching applications. |
| IC (continuous) | -2.5 A - Supports sustained high-side or low-side switching loads without derating at TA = 25°C. |
| VCE(sat) max | -220 mV @ -1A - Enables <117 mΩ effective on-resistance, minimizing conduction loss in power paths. |
| RθJA | 51 °C/W - Achieved on 10 cm² 1oz Cu PCB; enables higher power density vs. SOT-23 alternatives. |
| hFE | 275 min @ -3A - Ensures reliable base drive margin and stable gain under full-load saturation. |
| Package | DFN2020B-3 - 2.0 × 2.0 mm footprint, 0.6 mm height, exposed collector pad for thermal relief. |
| AEC-Q101 | Qualified - Validated for automotive-grade temperature cycling, humidity, and mechanical stress compliance. |
Pinout & Package
DFN2020B-3 is a 3-terminal, bottom-exposed thermal pad package with no leads; terminals are soldered directly to PCB pads. The collector connects to the exposed metal pad on the underside, while emitter and base occupy side terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (Pad) | High-current output node | Exposed copper pad on package underside - must be connected to large copper pour for thermal management and low-inductance return path. |
| Emitter | Current return path | Side terminal adjacent to marking; referenced to system ground or low-side rail in high-side switch configurations. |
| Base | Control input | Side terminal opposite emitter; requires current-limited drive (e.g., 100–200 mA) to achieve specified VCE(sat). |
Key Features
| Feature | Design Value |
|---|---|
| Low saturation voltage | VCE(sat) ≤ -220 mV at -1A ensures <0.22 W conduction loss per device in 1A switching paths. |
| Thermal performance | RθJA = 51°C/W (vs. 125°C/W for SOT-23) allows 2.4× higher power dissipation on same PCB area. |
| Space-efficient footprint | 4 mm² area - 50% smaller than SOT-23 - saves board space in multi-phase DC-DC and compact motor drivers. |
| AEC-Q101 qualification | Validated for automotive underhood environments (-40°C to +125°C ambient, 150°C junction). |
| Green construction | Lead-free, halogen-free, antimony-free molding compound compliant with RoHS and JEDEC MSL Level 1. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2022ZTA | -60V VCEO, -2A IC, RθJA = 62°C/W, same DFN2020B-3 package | Limited to ≤60V systems; lower current rating reduces margin in 48V charging or motor start-up surges | Select when voltage and current requirements are relaxed and cost sensitivity outweighs thermal headroom. |
| DMT3005LKQ | -100V VCEO, -3.5A IC, SO-8 package, RθJA = 70°C/W | Larger footprint (5×6 mm), higher thermal resistance, but superior voltage/current headroom | Choose for industrial 72V systems requiring >70V blocking or >2.5A surge tolerance, accepting larger board area. |
Compared with ZXTP722MATA, ZXTP2022ZTA trades voltage/current headroom for identical form factor, while DMT3005LKQ offers higher ratings in a larger, less thermally efficient package - making ZXTP722MATA optimal for AEC-Q101-compliant 48V automotive power stages where size and thermal performance are prioritized.

FAQ
What is the maximum allowable junction temperature for ZXTP722MATA?
The absolute maximum junction temperature is +150°C, as specified in the Thermal Characteristics table. Operation above this limit risks permanent degradation. Derating begins at +25°C ambient, with RθJA = 51°C/W on 10 cm² 1oz Cu - meaning maximum continuous power drops to ~2.45W at +100°C ambient.
Is ZXTP722MATA suitable for linear-mode operation?
Yes - it is characterized for linear use with VBE(on) and VBE(sat) specified across -10mA to -1.5A, and hFE maintained up to -3A. However, power dissipation must be strictly limited using the RθJA curve and board thermal design to avoid exceeding TJ = 150°C.
How does the DFN2020B-3 package improve thermal performance over SOT-23?
The DFN2020B-3's exposed collector pad provides direct thermal conduction to the PCB, achieving RθJA = 51°C/W - 60% lower than typical SOT-23 (125°C/W). This is validated on identical 10 cm² 1oz Cu test boards, enabling higher power handling without heatsinks.
Does ZXTP722MATA require special PCB layout considerations?
Yes - the exposed collector pad must be connected to a minimum 10 mm² copper pour with ≥4 thermal vias (0.3 mm diameter) to an internal ground plane. Pad layout must follow Diodes' recommended dimensions (D = 2.00 mm, E = 2.00 mm, D2 = 1.32 mm, E2 = 0.89 mm) to ensure solder joint reliability and thermal transfer.
