Product details
Overview
ZXTN26020DMFTA from Diodes Incorporated is a high-gain, low-VCE(SAT) NPN bipolar transistor in a DFN1411-3 package, rated for 1.5A continuous collector current, 20V VCEO, and qualified to AEC-Q101 for automotive reliability. It delivers RCE(SAT) = 90 mΩ at IC = 1A/ IB = 50mA and supports fast switching with ton = 60 ns, toff = 225 ns - used in MOSFET/IGBT gate driving and DC-DC converter output stages.
For engineers reviewing the ZXTN26020DMFTA datasheet, ZXTN26020DMFTA pinout, ZXTN26020DMFTA application, or ZXTN26020DMFTA equivalent, key selection criteria include verified low saturation voltage under high-current drive, AEC-Q101 qualification status, thermal resistance (RθJA = 330 °C/W on minimal pad layout), and DFN1411-3 footprint compatibility with space-constrained power interface designs.
Technical Context
This NPN transistor operates as a high-efficiency, low-loss switch in medium-power linear and switching applications. Its hFE = 200–1000 (at IC = 100mA–2A) enables robust base drive margin, while fT = 260 MHz supports stable operation up to high-frequency switching nodes.
The device uses a planar epitaxial structure with NiPdAu-plated copper lead frame and green molding compound (UL 94V-0). Thermal performance is defined for two PCB mounting conditions: 1"² pads (RθJA = 125 °C/W) and minimum recommended layout (RθJA = 330 °C/W), directly impacting derating in compact DC-DC modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum safe collector-emitter blocking voltage in common-emitter configuration, suitable for 12V rail switching. |
| IC (continuous) | 1.5 A - Sustained load current capability without thermal shutdown on standard FR-4 with minimal pad layout. |
| VCE(SAT) | 125 mV @ IC = 1A, IB = 50mA - Low conduction loss enabling <0.125 W dissipation per switch event at rated current. |
| RCE(SAT) | 90 mΩ - Equivalent on-resistance derived from VCE(SAT)/IC, critical for calculating I²R losses in gate-drive paths. |
| fT | 260 MHz - Gain-bandwidth product confirming usable frequency range up to ~100 MHz for fast turn-on/turn-off control. |
| toff | 225 ns - Total turn-off time including 205 ns storage delay, limiting maximum practical switching frequency to ≤2 MHz in hard-switched topologies. |
| AEC-Q101 | Qualified - Validated for automotive-grade temperature cycling, humidity, and mechanical stress per JESD22 standards. |
Pinout & Package
Package: DFN1411-3 (1.4 mm × 1.1 mm × 0.5 mm), molded plastic with NiPdAu-plated copper lead frame, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-side return path; lowest impedance node for heat extraction via exposed pad (if present). |
| 2 (Base) | Control input | Receives current-limited drive signal; requires ≥50 mA for full saturation at 1A collector load. |
| 3 (Collector) | Current source terminal | Switches positive rail to load; must withstand 20V transient spikes in inductive gate-drive applications. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VCE(SAT) | 125 mV at 1A enables <0.13 W conduction loss - reduces thermal load in space-constrained gate drivers. |
| AEC-Q101 qualification | Validated for automotive under-hood environments (-55°C to +150°C), supporting extended temperature reliability without derating. |
| DFN1411-3 footprint | 1.4 mm × 1.1 mm body size allows placement adjacent to power MOSFETs in half-bridge layouts with minimal PCB area. |
| High hFE consistency | hFE ≥ 200 at IC = 2A ensures stable saturation across production lots and temperature extremes. |
| Green RoHS compliance | Lead-, halogen-, and antimony-free construction meets EU Directive 2011/65/EU and automotive ELV requirements. |
Applications
| MOSFET Gate Driving | DC-DC Converter Output Stage |
|---|---|
|
Use Scenario: Driving the gate of a 30V N-channel MOSFET in a synchronous buck converter's high-side position. IC Role / Device Role / Timing Role: NPN switch providing fast, low-loss pull-down path during MOSFET turn-off to minimize shoot-through risk. Use Value: 225 ns toff and 90 mΩ RCE(SAT) reduce gate discharge time and resistive loss, improving efficiency by ~0.4% at 1A load. |
Use Scenario: Active clamping circuit in a flyback converter's secondary-side synchronous rectification stage. IC Role / Device Role / Timing Role: Low-VCE(SAT) NPN switch replacing Schottky diode to reduce forward voltage drop and conduction loss. Use Value: 125 mV VCE(SAT) at 1A cuts conduction loss by 55% versus 0.5V Schottky, lowering secondary-side temperature rise by 8°C. |
| Low-Voltage Interface Translation | LED Constant-Current Switching |
|
Use Scenario: Level-shifting logic signals from 3.3V microcontroller outputs to drive 12V solenoid loads. IC Role / Device Role / Timing Role: Medium-current NPN buffer isolating MCU GPIO from inductive back-EMF and providing gain for reliable saturation. Use Value: hFE ≥ 200 at IC = 1A ensures full saturation with only 5 mA base drive, reducing MCU I/O loading. |
Use Scenario: PWM-controlled current switch for high-brightness LED strings in automotive interior lighting. IC Role / Device Role / Timing Role: Fast-switching NPN transistor modulating LED current at 1–5 kHz with minimal dead-time distortion. Use Value: 60 ns ton and 20 ns td preserve PWM duty cycle fidelity, maintaining consistent luminance across dimming range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN25020DFH | Same DFN1411-3 package, but lower IC = 1.0A and higher VCE(SAT) = 175 mV @ 1A. | Not suitable for 1.5A gate-drive loads; acceptable only in low-current LED or logic interface roles. | Select only when thermal budget permits higher conduction loss and peak current demand is ≤1.0A. |
| DMT3005LPS-7 | 30V P-channel MOSFET in SOT-23; RDS(on) = 45 mΩ @ VGS = –4.5V, no base drive required. | Requires negative gate bias; unsuitable for direct TTL/CMOS drive without level shifter; better for high-side switching. | Prefer for high-side loads where gate drive voltage exceeds 4.5V; avoid if MCU lacks dedicated high-side driver or charge pump. |
Compared with ZXTN25020DFH and DMT3005LPS-7, ZXTN26020DMFTA uniquely balances 1.5A current handling, ultra-low 125 mV saturation voltage, and TTL-compatible base drive - making it optimal for compact, thermally constrained NPN switching where discrete BJT advantages (no gate capacitance, predictable hFE) outweigh MOSFET trade-offs.

FAQ
What is the maximum allowable junction temperature for ZXTN26020DMFTA?
The absolute maximum junction temperature is +150°C, as specified in the Absolute Maximum Ratings table. Operation above this limit risks permanent degradation of hFE and increased leakage. Derating is required above +25°C ambient based on RθJA = 330 °C/W for minimal pad layout - e.g., at +85°C ambient, max continuous power drops to 195 mW.
Does ZXTN26020DMFTA require a base resistor in all applications?
Yes - a series base resistor is mandatory to limit IB and ensure saturation without exceeding the 0.5A maximum base current rating. For 1A collector load and hFE = 200, minimum IB = 5 mA; with 3.3V drive, a 620 Ω resistor sets IB ≈ 5.3 mA, satisfying both saturation and safety margins.
Can ZXTN26020DMFTA be used in linear amplifier configurations?
No - it is optimized for switching operation, not linear amplification. The datasheet provides no small-signal parameters (e.g., rπ, gm) or linearity specifications. Its high hFE variation across IC and strong thermal dependence make it unsuitable for stable analog gain stages.
Is the DFN1411-3 package thermally enhanced with an exposed pad?
No - the DFN1411-3 package for ZXTN26020DMFTA has no exposed thermal pad. Thermal dissipation relies solely on the three soldered terminals and PCB copper area. The 330 °C/W RθJA value assumes minimal recommended pad layout per Figure 5 in DS31953 Rev. 2, not thermal vias or heatsinking.
