Product details
Overview
ZXTP19020CFF from Diodes Incorporated is a 20V PNP low-saturation-voltage transistor in SOT23F package, designed for high-current switching with VCE(SAT) < −40 mV at −1 A, −5 A continuous collector current, and AEC-Q101 qualification. It serves as a load switch or synchronous rectifier in battery charging and DC-DC converter power stages.
For engineers reviewing the ZXTP19020CFF datasheet, ZXTP19020CFF pinout, ZXTP19020CFF application, or ZXTP19020CFF equivalent, key selection criteria include verified −20 V VCEO, thermal resistance of 83.3 °C/W on 50 mm × 50 mm 2 oz Cu PCB, complementary pairing with ZXTN19020CFF, and RoHS-compliant "Green" construction.
Technical Context
This PNP bipolar junction transistor operates in linear and saturated switching modes, with guaranteed hFE ≥ 110 at −5 A and VCE = −2 V. Its low VCE(SAT) (−75 mV typ. at −2 A / −40 mA) enables high-efficiency power control in compact layouts.
The device features robust thermal performance: RθJA = 83.3 °C/W under optimized 50 mm × 50 mm 2 oz copper layout, and supports pulsed operation up to −10 A with safe operating area validated to 100 µs–1 s pulse widths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −20 V - Maximum reverse-biased collector-emitter voltage before breakdown; defines safe blocking capability in high-side switch configurations. |
| IC (Continuous) | −5 A - Sustained DC current handling; enables use in 5 A load switches without forced cooling. |
| VCE(SAT) | −40 mV @ −1 A / −100 mA - Confirmed low conduction loss; reduces power dissipation to 40 mW at rated current. |
| PD (Max) | 1.5 W - Peak steady-state power dissipation on 50 mm × 50 mm 2 oz Cu PCB; supports high-density power stage integration. |
| hFE | 110–500 - Wide DC current gain range across −100 mA to −5 A; ensures reliable base drive design across load conditions. |
| fT | 200 MHz - Transition frequency at −50 mA / −10 V; supports fast switching in PWM frequencies up to ~10 MHz. |
| RθJA | 83.3 °C/W - Verified thermal resistance on large copper area; enables 1.5 W operation with ≤125 °C junction rise above ambient. |
Pinout & Package
SOT23F is a low-profile, lead-free surface-mount package with exposed collector pad for enhanced thermal conduction. It maintains pin compatibility with standard SOT23 but delivers higher power density via improved thermal path and reduced height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current sink terminal; connected to system ground or return path in high-side switch topology. |
| 2 (Base) | B | Control input; requires −100 mA drive for full saturation at −1 A collector current. |
| 3 (Collector) | C | Power output node; electrically tied to exposed pad for direct PCB thermal coupling and current routing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HBM ESD (4 kV), and mechanical stress testing. |
| Low-profile SOT23F package | Height ≤ 1.0 mm; enables ultra-thin power modules and space-constrained portable electronics designs. |
| Halogen- and antimony-free "Green" construction | Meets <900 ppm Br/Cl and <1000 ppm Sb; compliant with global environmental regulations beyond RoHS. |
| Complementary NPN pairing | ZXTN19020CFF shares identical package, ratings, and thermal profile-enabling matched push-pull or H-bridge implementations. |
Applications
| Battery Charging Circuits | Load Switching in Portable Devices |
|---|---|
Use Scenario: Bidirectional charging control in USB PD or wireless power receivers where reverse current blocking and low-loss discharge are required. IC Role / Device Role / Timing Role: PNP transistor used as active reverse-polarity protection and charge-path switch in series with battery terminals. Use Value: −40 mV VCE(SAT) minimizes voltage drop during charging, preserving battery capacity and reducing thermal load in sealed enclosures. | Use Scenario: Power rail enable/disable for subsystems like displays, sensors, or RF modules in wearables and IoT edge nodes. IC Role / Device Role / Timing Role: High-side load switch controlling 3.3 V or 5 V domain power delivery with fast turn-on/turn-off response. Use Value: 200 MHz fT and sub-100 ns switching times support precise sequencing and transient suppression in multi-rail systems. |
| DC-DC Converter Synchronous Rectification | Automotive Body Control Modules |
Use Scenario: Secondary-side synchronous rectifier in isolated flyback or forward converters delivering up to 5 A output. IC Role / Device Role / Timing Role: PNP switch replacing Schottky diode to reduce conduction loss and improve efficiency at light-to-full load. Use Value: −75 mV VCE(SAT) at −2 A cuts conduction loss by >60% vs. typical 0.35 V Schottky, directly improving conversion efficiency. | Use Scenario: LED driver and solenoid control in door lock actuators, mirror adjusters, and interior lighting within AEC-Q101-compliant BCMs. IC Role / Device Role / Timing Role: Robust switching element driving inductive loads with integrated flyback protection and thermal margin. Use Value: AEC-Q101 qualification and −55 °C to +150 °C operating range ensure functional safety compliance and long-term field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-current switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP20020CFF | Higher VCEO (−25 V), lower hFE (min 80 @ −5 A), same SOT23F package | Better suited for 24 V industrial rails; slightly reduced current gain requires stronger base drive | Select when higher blocking voltage is needed and base drive capability allows for lower hFE. |
| MMDT3906-7-F | Lower IC (−200 mA), smaller SOT-363 package, no AEC-Q101 rating | Only suitable for signal-level switching; not interchangeable for 5 A load switching | Use only for low-power biasing or logic inversion-not as a functional replacement in power applications. |
Compared with ZXTP19020CFF, ZXTP20020CFF offers extended voltage headroom at the cost of gain margin, while MMDT3906-7-F is functionally incompatible for power switching due to its 200 mA rating and lack of automotive qualification.

FAQ
What is the maximum continuous collector current for ZXTP19020CFF?
The ZXTP19020CFF supports −5 A continuous collector current at TA = +25 °C with proper PCB thermal management (50 mm × 50 mm 2 oz Cu). Derating applies above +25 °C ambient per the 12.0 mW/°C linear derating factor specified in Note 7 of the datasheet.
Is ZXTP19020CFF pin-compatible with standard SOT23?
Yes - the SOT23F package uses the same 3-pin footprint and pinout (E-B-C) as industry-standard SOT23, enabling drop-in replacement in existing layouts. However, SOT23F has a lower profile (≤1.0 mm height) and an exposed collector pad for superior thermal performance.
Does ZXTP19020CFF require a heatsink in typical applications?
No external heatsink is required when mounted on ≥25 mm × 25 mm 2 oz copper PCB, as RθJA drops to 93.4 °C/W. At 1.5 W dissipation and 25 °C ambient, junction temperature remains below 165 °C - within the −55 °C to +150 °C operating limit.
How does the AEC-Q101 qualification impact design validation?
AEC-Q101 qualification confirms ZXTP19020CFF has passed accelerated stress tests including temperature cycling, HBM ESD (4 kV), and high-temperature operating life - eliminating need for requalification in automotive body electronics, infotainment, and ADAS auxiliary power systems.
