Product details
Overview
ZXTN619MATA from Diodes Incorporated is a 50V NPN low-saturation transistor in U-DFN2020-3 package, designed for high-current switching in power stages. It delivers 4A continuous collector current, achieves ≤100mV VCE(sat) at 1A, exhibits 68mΩ equivalent on-resistance, and maintains hFE ≥200 up to 6A - enabling efficient MOSFET gate driving and DC-DC converter primary-side switching.
For engineers reviewing the ZXTN619MATA datasheet, ZXTN619MATA pinout, ZXTN619MATA application, or ZXTN619MATA equivalent, key selection criteria include its 50V VCEO, 0.6mm profile, 83°C/W RθJA (on 10cm² 1oz Cu), JEDEC-qualified reliability, and automotive-grade Q-suffix variants for AEC-Q101-compliant designs.
Technical Context
This NPN bipolar junction transistor operates as a high-efficiency, low-VCE(sat) switch in saturated mode, with BVCEO = 50V and IC = 4A continuous rating. Its hFE is specified from 10mA to 6A, supporting stable gain across wide load ranges in motor control and charging circuits.
The U-DFN2020-3 (Type B) package integrates an exposed collector pad for thermal conduction, achieving RθJL = 16.8°C/W and 60% lower RθJA than SOT23. ESD ratings meet HBM 4kV, MM 400V, and CDM 1kV per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50V - supports 24V/36V industrial and automotive power rails with margin. |
| IC (continuous) | 4A - enables direct drive of medium-power MOSFET gates or small motors without external buffering. |
| VCE(sat) max | 100mV @ 1A - reduces conduction loss to <100mW, critical for thermally constrained thin applications. |
| RSAT | 68mΩ - quantifies effective on-resistance for loss modeling in switching node calculations. |
| hFE | 200–450 @ IC = 10mA–6A - ensures reliable base drive design across full operating range. |
| fT | 100–165MHz - supports fast switching in DC-DC converters up to ~500kHz with minimal delay. |
| RθJA | 83°C/W (on 10cm² 1oz Cu) - enables 1.5W dissipation at +25°C ambient without forced cooling. |
Pinout & Package
Package: U-DFN2020-3 (Type B), 2.0 × 2.0 × 0.6 mm, exposed collector pad on bottom surface, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Top Marking "SC") | Emitter | Reference terminal for base-emitter bias; connected to ground or low-side return path. |
| Pin 2 | Base | Current-controlled input; requires 200mA drive for 4A collector switching under saturation. |
| Pin 3 (Exposed Pad) | Collector | Primary power terminal and thermal interface; must be soldered to ≥10cm² copper for rated PD. |
Key Features
| Feature | Design Value |
|---|---|
| Low saturation voltage | VCE(sat) ≤100mV @ 1A - cuts conduction loss by >50% vs. standard SOT23 transistors at same current. |
| High current gain at full load | hFE ≥200 @ IC = 6A - allows simplified base drive circuitry without Darlington staging. |
| Thermal efficiency | RθJA = 83°C/W - enables 1.5W operation on minimal PCB copper, reducing heatsink dependency. |
| Space-constrained footprint | 4mm² area, 50% smaller than SOT23 - fits dense power management layouts in portable and automotive ECUs. |
| JEDEC-qualified reliability | Qualified to AEC-Q101 stress test conditions - supports production use in automotive power modules. |
Applications
| MOSFET Gate Driving | DC-DC Converter Switching |
|---|---|
|
Use Scenario: Driving the gate of a 30V/50A N-channel MOSFET in a synchronous buck converter. IC Role / Device Role / Timing Role: High-current NPN switch providing rapid turn-on pulse with low VCE(sat) to minimize Miller plateau time. Use Value: 100mV saturation drop ensures <100mW loss during gate charge, improving efficiency and thermal margin. |
Use Scenario: Low-side switch in 12V-to-5V non-synchronous buck regulator for infotainment subsystems. IC Role / Device Role / Timing Role: Primary power switch handling peak currents up to 4A at 250kHz switching frequency. Use Value: 165MHz fT and 750ns toff support clean transitions with minimal switching loss. |
| Charging Circuit Control | Motor Control Interface |
|
Use Scenario: Enabling/disabling battery charging path in USB-C PD power banks with 20V input. IC Role / Device Role / Timing Role: High-side or low-side enable switch controlling charging FET gate or current sense path. Use Value: 50V VCEO accommodates 20V input with 2.5× safety margin; 4A rating covers 10W+ charging loads. |
Use Scenario: Directional control and current limiting in 24V brushed DC motor drivers for HVAC actuators. IC Role / Device Role / Timing Role: Current-sense amplifier front-end switch or H-bridge half-bridge driver stage. Use Value: Stable hFE up to 6A ensures predictable base drive across motor stall and dynamic load conditions. |
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 |
|---|---|---|---|
| ZXTN618MATA | VCEO = 40V, VCE(sat) = 120mV @ 1A, hFE = 150–350 @ 6A | Limited to ≤36V systems; higher saturation loss reduces efficiency in high-duty-cycle apps. | Select when 40V rating suffices and cost sensitivity outweighs thermal performance. |
| DMT6009LPS-13 | N-channel MOSFET (60V, 9.5mΩ, SO-8), gate threshold 1–2.5V, no base current required | Zero gate drive current, lower RDS(on), but larger footprint and higher gate charge vs. BJT simplicity. | Prefer for ultra-low-loss, high-frequency (>1MHz) switching where gate drive complexity is acceptable. |
Compared with ZXTN618MATA, ZXTN619MATA offers +10V breakdown margin and 20mV lower VCE(sat); versus DMT6009LPS-13, it provides smaller size and simpler drive but trades off conduction efficiency above 2A.

FAQ
What is the maximum safe operating temperature for ZXTN619MATA?
The ZXTN619MATA has a junction temperature limit of +150°C and storage range of −55°C to +150°C. With RθJA = 83°C/W on 10cm² 1oz Cu, it sustains 1.5W dissipation at +25°C ambient. Derating begins linearly above +25°C at 12mW/°C, reaching zero power at +150°C case temperature.
Is ZXTN619MATA suitable for automotive applications?
Yes - the ZXTN619MATA is JEDEC-qualified and compatible with AEC-Q101 stress testing. Diodes offers automotive-grade variants (e.g., ZXTN619MAQ) manufactured in IATF 16949-certified facilities, PPAP-capable, and qualified to AEC-Q101 Rev G for under-hood and body-control module use.
How should the exposed collector pad be soldered for thermal performance?
The exposed collector pad (Pin 3) must be fully soldered to ≥10cm² of 1oz copper on a single-sided FR-4 PCB for rated RθJA = 83°C/W. Use a 2×2 array of thermal vias (0.3mm diameter, 0.6mm pitch) connecting to internal or backside ground planes to improve heat spreading and reduce RθJA to ~51°C/W.
Does ZXTN619MATA require a base resistor, and how is it calculated?
Yes - a base resistor limits IB to prevent overdrive and ensure saturation. For 4A IC and hFE(min) = 200, minimum IB = 20mA. With VBE(sat) ≈ 1.07V and 3.3V logic drive, RB = (3.3V − 1.07V)/20mA = 112Ω. Use 100Ω ±5% for margin, verified via VCE(sat) measurement at full load.
