Product details
Overview
ZXTN620MATA from Diodes Incorporated is an 80V NPN low-saturation transistor in DFN2020B-3 package, rated for 3.5A continuous collector current, with VCE(sat) ≤ 185 mV at 1A/20mA drive and RSAT = 68 mΩ. It serves as a high-efficiency power switch in DC–DC converters and motor control circuits where thermal efficiency and thin-profile mounting are critical.
For engineers reviewing the ZXTN620MATA datasheet, ZXTN620MATA pinout, ZXTN620MATA application, or ZXTN620MATA equivalent, key selection criteria include its AEC-Q101 qualification, 0.6mm profile, 51°C/W RθJA (on 10 cm² 1oz Cu), and hFE ≥ 200 up to 3A - all verified under pulsed test conditions per DS31894 Rev. 5-2.
Technical Context
This NPN transistor operates with BVCEO = 80 V and VEBO = 7 V, supporting robust voltage margin in switching applications. Its fT = 100–160 MHz enables fast switching, while ton/toff = 86 ns / 1128 ns reflect optimized charge storage for medium-speed power control.
The device uses a pre-plated NiPdAu leadframe and green molding compound, qualified to AEC-Q101 for automotive-grade reliability. Thermal performance is defined with full collector-pad soldering to PCB copper - RθJL = 16.8°C/W confirms efficient heat extraction through the exposed drain pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - supports 48V bus systems with 67% voltage headroom before breakdown |
| IC (continuous) | 3.5 A - delivers >3W dissipation capability on standard FR4 with 10 cm² copper |
| VCE(sat) @ 1A | ≤ 185 mV - reduces conduction loss to <185 mW at 1A, enabling >95% efficiency in low-VOUT buck stages |
| RSAT | 68 mΩ - equivalent on-resistance simplifies loss modeling vs. MOSFETs in bipolar gate-drive roles |
| hFE @ 3A | ≥ 200 - ensures stable base drive requirement of ≤15 mA for full 3.5A switching |
| fT | 100–160 MHz - supports clean turn-on/turn-off in PWM frequencies up to 500 kHz |
| RθJA | 51°C/W - 60% lower than SOT-23, enabling higher power density without forced air |
Pinout & Package
Package: DFN2020B-3, 2.0 mm × 2.0 mm × 0.6 mm, thermally enhanced with exposed collector pad (pin 1). Molded plastic case, NiPdAu-plated terminals, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Collector) | Main current sink terminal | Exposed copper pad - must be soldered to ≥10 cm² 1oz Cu for rated RθJA = 51°C/W |
| 2 (Base) | Current-controlled input | Drives transistor into saturation; requires 300 mA peak for 3.5A IC per datasheet test condition |
| 3 (Emitter) | Current return path | Connected to ground or low-side reference; forms common-emitter switching topology |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power modules requiring -55°C to +150°C operation and humidity resistance |
| Low-profile 0.6 mm height | Enables integration into space-constrained portable power supplies and battery management PCBs |
| RθJA = 51°C/W | Reduces thermal derating by 60% vs. SOT-23, allowing 2.45 W continuous dissipation on minimal copper |
| hFE specified up to 5 A | Supports accurate gain-based base drive design across full load range without extrapolation |
| Lead-free, halogen-free "Green" construction | Complies with RoHS and JEDEC J-STD-020 Level 1 moisture sensitivity for standard reflow |
Applications
| MOSFET Gate Driving | DC–DC Converters |
|---|---|
Use Scenario: Driving high-side N-channel MOSFET gates in synchronous buck regulators. IC Role / Device Role / Timing Role: NPN switch providing low-impedance pull-down path during dead-time to prevent shoot-through. Use Value: VCE(sat) ≤ 185 mV at 1A ensures gate discharge energy loss stays below 0.2 mJ per cycle, minimizing driver heating. | Use Scenario: Low-voltage, high-current output stage in 12V-to-3.3V point-of-load converters. IC Role / Device Role / Timing Role: Saturated-switch regulator element operating in linear or quasi-resonant mode. Use Value: RSAT = 68 mΩ enables <100 mW conduction loss at 1.2A, improving light-load efficiency over MOSFET alternatives. |
| Charging Circuits | Motor Control |
Use Scenario: Constant-current switch in USB-C PD or Li-ion battery charging paths. IC Role / Device Role / Timing Role: Precision current-regulating pass element controlled via feedback loop. Use Value: hFE stability from 10 mA to 3.5A allows single-loop analog current sensing without gain compensation. | Use Scenario: H-bridge low-side switch in 24V brushed DC motor drivers for industrial actuators. IC Role / Device Role / Timing Role: High-current saturated switch handling bidirectional stall currents up to 3.5A. Use Value: 80V VCEO rating provides 3× margin over 24V rail transients, reducing need for snubbers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low-saturation transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2010ZTA | VCEO = 100 V, IC = 2.5 A, VCE(sat) = 220 mV @ 1A | Higher voltage margin but lower current and higher saturation loss | Select when 100V breakdown is mandatory and 2.5A suffices |
| DMT3006LPSQ-13 | 60V VDS, 6A ID, MOSFET with 22mΩ RDS(on) | Lower on-resistance but requires gate drive circuitry and lacks inherent current gain | Select when gate drive resources exist and <100mΩ on-state resistance is prioritized over simplicity |
Compared with ZXTN2010ZTA, ZXTN620MATA delivers 40% higher current and 19% lower VCE(sat); versus DMT3006LPSQ-13, it eliminates gate driver complexity but trades off 3× on-resistance - making it optimal for cost-sensitive, moderate-frequency, low-component-count power switches.

FAQ
What is the maximum continuous collector current for ZXTN620MATA under standard PCB conditions?
The ZXTN620MATA supports 3.5 A continuous collector current when mounted on a 31 mm × 31 mm FR4 board with full 1 oz copper coverage on the collector pad, per Note 3 in DS31894 Rev. 5-2. Derating begins above 25°C ambient at 19.6 mW/°C for this configuration.
Is ZXTN620MATA suitable for automotive applications?
Yes - ZXTN620MATA is qualified to AEC-Q101 standards, with guaranteed operation from −55°C to +150°C junction temperature, moisture sensitivity level 1, and green RoHS-compliant construction. It is approved for use in engine control, body electronics, and ADAS power stages.
How does the DFN2020B-3 package improve thermal performance over SOT-23?
The DFN2020B-3 package achieves RθJA = 51°C/W - 60% lower than typical SOT-23 - due to its exposed collector pad directly soldered to PCB copper, larger thermal interface area (4 mm² footprint), and optimized internal thermal path to the leadframe, not just package geometry.
Can ZXTN620MATA replace a MOSFET in gate-driving applications?
Yes - its low VCE(sat) (≤185 mV) and high hFE (>200 at 3A) allow direct replacement of small-signal MOSFETs in low-side gate discharge paths, eliminating gate driver ICs and reducing component count, especially where fast turn-off is less critical than simplicity and cost.
