Product details
Overview
ZXTP25020CFFTA from Diodes Incorporated is a 20V PNP medium-power transistor in SOT23F package, designed for high-side switching and reverse-blocking battery charging circuits. It delivers -4.5A continuous collector current, -65mV VCE(SAT) at -1A, 41mΩ RCE(SAT), and supports AEC-Q101 automotive qualification.
For engineers reviewing the ZXTP25020CFFTA datasheet, ZXTP25020CFFTA pinout, ZXTP25020CFFTA application, or ZXTP25020CFFTA equivalent, key selection criteria include reverse blocking capability (VECO = -7V), thermal resistance (RθJL = 60°C/W), and saturation voltage performance under high-current drive conditions.
Technical Context
This PNP bipolar transistor features reverse emitter-collector blocking (VECO = -7V), enabling elimination of external Schottky diodes in battery charging paths. Its low RCE(SAT) (41mΩ) and characterized hFE up to -10A support robust gate driving for MOSFETs and IGBTs.
The SOT23F package integrates an exposed collector pad for enhanced thermal conduction, with RθJL = 60°C/W to solder-point and RθJA as low as 63.7°C/W on 50mm×50mm 2oz copper - critical for portable power management where board space and thermal headroom are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20V - Maximum safe collector-emitter voltage in normal forward-active operation |
| VECO | -7V - Reverse blocking voltage enables diode-free battery disconnect in charging circuits |
| IC (cont.) | -4.5A - Continuous current rating defines usable load-switching capacity at ambient temperature |
| VCE(SAT) | < -65mV @ -1A - Low saturation voltage minimizes conduction loss in high-side switch applications |
| RCE(SAT) | 41mΩ - On-resistance derived from VCE(SAT)/IC; enables accurate power loss estimation |
| PD | 1.5W - Maximum steady-state power dissipation with appropriate PCB copper area |
| hFE | 85–500 @ IC = -10mA to -10A - Wide gain range supports stable biasing across operating currents |
Pinout & Package
The ZXTP25020CFFTA is housed in a surface-mount SOT23F package with an exposed collector pad for thermal enhancement. Dimensions conform to AP02001: 2.90mm × 2.40mm × 0.90mm (L × W × H), with 0.95mm lead pitch and matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Current sink node; connects to load or battery positive in high-side configuration |
| 2 (Base) | Control input | Receives negative base current to turn on; requires current-limiting resistor in driver stage |
| 3 (Collector) | Power output / heat path | Connected to system ground or low-impedance return; exposed pad provides primary thermal conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Reverse emitter-collector blocking | VECO = -7V eliminates need for series Schottky diode in battery charge path |
| Low saturation voltage | VCE(SAT) < -65mV @ -1A reduces conduction loss and self-heating in portable DC-DC stages |
| High current gain characterization | hFE specified up to -10A ensures predictable drive requirements across full load range |
| AEC-Q101 qualification | Qualified for automotive-grade reliability including temperature cycling and ESD (HBM 4kV) |
Applications
| Mobile Phone Charging Circuits | MOSFET and IGBT Gate Drivers |
|---|---|
Use Scenario: Battery isolation during USB/adapter charging to prevent backfeed into system rails. IC Role / Device Role / Timing Role: High-side PNP switch providing reverse-blocking path control between charger and battery. Use Value: Eliminates external Schottky diode, reducing BOM count and forward voltage drop by ~300mV. | Use Scenario: Driving gates of N-channel power devices in half-bridge or synchronous rectifier topologies. IC Role / Device Role / Timing Role: Fast-turn-on PNP current source delivering high peak base current (-225mA) to reduce switching transition time. Use Value: Achieves tF = 55ns and tS = 168ns, improving efficiency in <1MHz switching converters. |
| High-Side Driving | DC-DC Converters |
Use Scenario: Controlling power delivery to subsystems (e.g., display backlight, sensor array) from main battery rail. IC Role / Device Role / Timing Role: Medium-power load switch with fast turn-off and low leakage (<1nA ICBO). Use Value: Enables precise power sequencing with <1µA standby current and <100ns delay time (tD = 38.4ns). | Use Scenario: Output stage switching in buck or SEPIC regulators requiring reverse-blocking capability. IC Role / Device Role / Timing Role: Synchronous rectifier replacement or freewheeling switch in non-isolated topologies. Use Value: Delivers RCE(SAT) = 41mΩ and fT = 285MHz, supporting efficient operation up to 500kHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2020ZTA | VCEO = -20V, IC = -2A, VCE(SAT) = -100mV @ -1A, SOT23 package (no exposed pad) | Lower current and higher saturation voltage; lacks reverse blocking (VECO not rated) | Select when cost sensitivity outweighs thermal performance and reverse-blocking requirement |
| DMT3005LKQ | VCEO = -30V, IC = -5A, VCE(SAT) = -85mV @ -2A, SOT23F package, no AEC-Q101 | Higher voltage rating and current, but unqualified for automotive use and unspecified VECO | Choose for industrial DC-DC where extended voltage margin is needed and automotive qualification is unnecessary |
Compared with ZXTP25020CFFTA, ZXTP2020ZTA trades off reverse blocking and thermal performance for lower cost, while DMT3005LKQ offers higher voltage headroom but lacks automotive qualification and confirmed reverse-blocking capability - making ZXTP25020CFFTA uniquely suited for AEC-Q101-compliant battery protection designs.

FAQ
What is the maximum safe operating junction temperature for ZXTP25020CFFTA?
The device is rated for TJ from -55°C to +150°C. At maximum ambient temperature (+105°C) with 50mm×50mm 2oz copper, its 1.5W power rating allows ~10W pulse capability for short durations (t < 5s), but continuous operation must stay within derated limits defined by RθJA = 63.7°C/W.
Can ZXTP25020CFFTA replace a Schottky diode in battery charging paths?
Yes - its -7V VECO rating enables reverse blocking without external diodes. When used as a high-side switch with emitter to battery and collector to load, it blocks reverse current during adapter disconnection, eliminating typical 300–400mV Schottky forward drop and associated heat generation.
Is the SOT23F package lead-free and RoHS compliant?
Yes - ZXTP25020CFFTA is fully RoHS compliant (2011/65/EU), lead-free, halogen-free, and antimony-free per Diodes Incorporated's "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb). Terminal finish is matte tin, solderable per MIL-STD-202, Method 208.
How does the exposed collector pad affect thermal design?
The exposed collector pad in SOT23F provides a direct thermal path to PCB copper. With RθJL = 60°C/W to the solder point, thermal performance improves significantly versus standard SOT23 - especially when paired with ≥25mm² of 2oz copper under the pad, enabling higher continuous current in space-constrained layouts.
