Product details
Overview
ZXTN617MATA from Diodes Incorporated is a 15V NPN low-saturation transistor in DFN2020B-3 package, rated for 4.5A continuous collector current, 15V VCEO, and 100mV max VCE(sat) at 1A. It serves as a high-current switching element in power conversion stages, delivering low on-resistance (RSAT = 45 mΩ) and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the ZXTN617MATA datasheet, ZXTN617MATA pinout, ZXTN617MATA application, or ZXTN617MATA equivalent, key selection criteria include its 0.6mm profile for space-constrained PCBs, thermal resistance of 51°C/W (on 1oz Cu), and hFE ≥ 150 up to 5A - critical for gate driving and motor control where gain stability under load matters.
Technical Context
This NPN transistor operates in linear or saturated switching mode with pulsed VCE(sat) tested at ≤300 µs width and ≤2% duty cycle. Its hFE is specified across five current points (10mA–12A), confirming gain retention at high drive levels - essential for MOSFET gate drivers requiring consistent base current scaling.
The DFN2020B-3 package integrates an exposed collector pad directly bonded to PCB copper, enabling RθJL = 16.8°C/W and reducing thermal impedance by 60% versus SOT23. Electrical isolation between emitter and base terminals supports safe operation up to 7V VEBO and 40V VCBO.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 15 V - Maximum safe collector-emitter voltage during switching; defines upper rail limit in DC–DC converters. |
| IC (continuous) | 4.5 A - Sustained current handling without derating on 10 cm² 1oz Cu PCB; enables compact high-current switch design. |
| VCE(sat) @ 1A | ≤100 mV - Low conduction loss reduces heat generation and improves efficiency in battery-powered charging circuits. |
| hFE @ 5A | ≥150 - Stable current gain at high collector current ensures predictable base drive requirements for power MOSFET gates. |
| RθJA | 51 °C/W - Measured on 10 cm² board; allows 2.45W dissipation before reaching 150°C junction limit at 25°C ambient. |
| fT | 80–120 MHz - High-frequency gain bandwidth supports fast switching transitions in PWM-based motor control. |
| Package | DFN2020B-3 - 2.0 × 2.0 mm footprint, 0.6 mm height; 50% smaller area than SOT23 for ultra-thin applications. |
Pinout & Package
DFN2020B-3 is a 3-terminal surface-mount package with exposed collector pad (pin 1), emitter (pin 2), and base (pin 3). The top marking "SA" identifies the device; thermal performance relies on full solder coverage of the bottom collector pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Collector) | Main current output path | Exposed metal pad - must be soldered to large copper pour for thermal management and low-inductance return path. |
| Pin 2 (Emitter) | Current return node | Connected to ground or low-side reference; forms low-impedance path for saturation-mode operation. |
| Pin 3 (Base) | Control input | Receives current-limited drive signal; requires ≥50 mA for full 4.5A switching to maintain VCE(sat) ≤200 mV. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−55°C to +150°C) and mechanical stress, supporting under-hood applications. |
| RSAT = 45 mΩ | Equivalent on-resistance enables <100 mW conduction loss at 1A - critical for thermally constrained DC–DC modules. |
| hFE up to 12A | Guaranteed minimum gain at extreme currents ensures robust gate drive capability even as MOSFET Qg increases with voltage. |
| 0.6 mm profile | Enables stacking with adjacent components in ultra-low-profile power supplies and portable battery chargers. |
| Lead-free & halogen-free | Complies with RoHS and JEDEC MSL Level 1 - no baking required prior to reflow, simplifying manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2010ZTA | Higher VCEO (20V), lower IC (3A), same DFN2020B-3 package | Better suited for 18V systems but limited peak current handling | Select when higher breakdown margin is needed over absolute current capacity. |
| DMT3005LKQ | 50V VCEO, 3.5A IC, SOT-23 package, higher RθJA (150°C/W) | Compatible footprint not available; requires board redesign and thermal reassessment | Choose only if legacy SOT-23 layout must be retained and 50V rating is mandatory. |
Compared with ZXTN2010ZTA and DMT3005LKQ, ZXTN617MATA uniquely balances 4.5A current, 15V rating, and ultra-low thermal resistance in a 2×2 mm footprint - making it optimal for space- and thermally constrained automotive and industrial switching nodes where both current density and reliability are prioritized.

FAQ
What is the maximum continuous collector current for ZXTN617MATA under standard PCB conditions?
The ZXTN617MATA supports 4.5A continuous collector current when mounted on a 31mm × 31mm FR4 PCB with full 1oz copper coverage on one side and the exposed collector pad fully soldered to the copper plane. This rating assumes still-air conditions and steady-state thermal equilibrium at 25°C ambient.
Does ZXTN617MATA require special PCB layout considerations for thermal performance?
Yes - optimal thermal performance requires full-solder coverage of the exposed collector pad (Pin 1) to a minimum 10 cm² copper area. The DFN2020B-3 footprint uses a thermal pad that must be connected to internal or external ground planes via multiple vias to achieve the specified 51°C/W RθJA.
Is ZXTN617MATA suitable for linear regulator applications?
No - while ZXTN617MATA can operate in the linear region, its design emphasis is on low-saturation switching, not voltage regulation. The device lacks built-in thermal shutdown or safe operating area (SOA) guarantees for sustained linear operation; use is restricted to pulsed or saturated-mode switching per datasheet SOA curves.
How does the hFE specification support gate-driving applications?
ZXTN617MATA's hFE is guaranteed ≥150 at 5A collector current, ensuring predictable base drive current (e.g., ~33 mA for 5A output). This enables precise sizing of base resistors in gate-driver circuits and maintains switching speed consistency across temperature and load variations.
