Product details
Overview
ZXTP720MATA from Diodes Incorporated is a 40V PNP low-saturation switching transistor in DFN2020B-3 package, rated for -3A continuous collector current, -220mV max VCE(sat) at -1A, and 104 mΩ equivalent on-resistance. It serves as a high-current power switch in DC-DC converters and motor control circuits where compact size and thermal efficiency are critical.
For engineers reviewing the ZXTP720MATA datasheet, ZXTP720MATA pinout, ZXTP720MATA application, or ZXTP720MATA equivalent, key selection criteria include its AEC-Q101 qualification, 0.6mm profile, RθJA = 83°C/W (on 10 cm² FR4), -40V VCEO, and hFE maintained up to -3A - all essential for automotive-grade power switching designs.
Technical Context
This PNP bipolar junction transistor operates with emitter-grounded configuration and supports high-current switching via base-driven saturation control. Its low RSAT (104 mΩ) and specified hFE down to -3A enable stable gain hold-up under heavy load conditions typical in gate driving and charging circuits.
The DFN2020B-3 package integrates an exposed collector pad for direct thermal coupling to PCB copper, delivering 60% lower RθJA than SOT-23 and enabling higher power density in space-constrained applications such as thin-profile power modules and portable battery management systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -40 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (cont) | -3 A - Continuous collector current rating defines maximum steady-state switching capacity |
| VCE(sat) | -220 mV max @ -1A - Low saturation voltage minimizes conduction loss and self-heating |
| RSAT | 104 mΩ - Equivalent on-resistance derived from VCE(sat)/IC, critical for power loss calculation |
| hFE | 12–480 - Current gain specified across IC = -10mA to -3A, supporting robust drive margin at full load |
| RθJA | 83 °C/W - Thermal resistance to ambient on 10 cm² 1oz Cu FR4, enabling 1.5W dissipation at TA = 25°C |
| Package | DFN2020B-3 - 2.0×2.0 mm, 0.6 mm height, exposed collector pad for thermal enhancement |
Pinout & Package
DFN2020B-3 is a 3-terminal, leadless surface-mount package with an exposed collector pad on the bottom. The package height is 0.6 mm, footprint is 4 mm² (50% smaller than SOT-23), and thermal performance is optimized via direct PCB copper attachment of the collector terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Top Marking Side Left) | Emitter (E) | Current source terminal; connected to higher potential in PNP switching configuration |
| Pin 2 (Top Marking Side Right) | Base (B) | Control input; requires negative current injection relative to emitter to saturate device |
| Pin 3 (Bottom Exposed Pad) | Collector (C) | Main current sink terminal; thermally and electrically tied to PCB copper for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics per stress test requirements including HTOL, TC, HTRB |
| Low-profile DFN package | 0.6 mm height enables integration into ultra-thin power modules and portable chargers |
| RθJA 60% lower than SOT-23 | Enables 1.5 W continuous power dissipation without heatsink on standard FR4 layout |
| hFE specified up to -3A | Ensures predictable base drive requirements and gain stability at full rated current |
| Lead-free, halogen-free "Green" construction | Complies with RoHS Directive 2011/65/EU and JEDEC JS709B environmental standards |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2028GTA | VCEO = -20V, IC = -2.5A, RθJA = 100°C/W, same DFN2020B-3 package | Limited to ≤12V systems; lower current and thermal capability restrict use in 24V motor control | Select when lower voltage rating and reduced cost are acceptable trade-offs for space-constrained 12V applications |
| DMT3005LKQ-7 | VCEO = -30V, IC = -3.5A, SOT-23 package, RθJA = 200°C/W | Higher current but significantly worse thermal performance; requires external heatsinking above 0.75W | Prefer only if board layout prohibits DFN packages and thermal budget allows discrete heatsink integration |
Compared with ZXTP2028GTA and DMT3005LKQ-7, ZXTP720MATA uniquely balances -40V rating, -3A current, and 83°C/W thermal resistance in a 0.6mm profile - making it optimal for AEC-Q101-compliant 24V automotive power switches where board space and self-heating are co-constrained.

FAQ
What is the maximum allowable continuous collector current for ZXTP720MATA?
The ZXTP720MATA is rated for -3 A continuous collector current (IC) when mounted on a 31 mm × 31 mm FR4 PCB with 1 oz copper and operated at TA = 25°C. Derating applies above 25°C ambient, with linear reduction of 12 mW/°C per the datasheet's thermal specification.
Does ZXTP720MATA require a heatsink in typical applications?
No external heatsink is required for ZXTP720MATA in most applications due to its DFN2020B-3 package with exposed collector pad. At 1.5 W dissipation and 25°C ambient, the junction temperature remains below 150°C using only 10 cm² of 1 oz copper - verified per Note 4 in DS31883 Rev. 5-2.
How does the DFN2020B-3 package improve thermal performance over SOT-23?
The DFN2020B-3 achieves 60% lower RθJA (83°C/W vs. ~200°C/W for SOT-23) by integrating a large exposed collector pad directly soldered to PCB copper. This provides low-impedance thermal conduction paths and eliminates bond wire and plastic body thermal bottlenecks inherent in leaded packages.
Is ZXTP720MATA suitable for automotive applications?
Yes - ZXTP720MATA is qualified to AEC-Q101 standards, covering stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and high-temperature reverse bias (HTRB). Its -55°C to +150°C operating range and green, halogen-free construction meet automotive electronics requirements.
