Product details
Overview
ZXTP2025FTA from Diodes Incorporated is a 50V PNP medium-power bipolar junction transistor in SOT23 (Type DN) package, rated for -5A continuous collector current and -10A peak pulse current, with low saturation voltage of -60mV max at -1A, RCE(sat) = 30mΩ, and 1.2W power dissipation - optimized for high-side switching in DC-DC converters and MOSFET/IGBT gate driving.
For engineers reviewing the ZXTP2025FTA datasheet, ZXTP2025FTA pinout, ZXTP2025FTA application, or ZXTP2025FTA equivalent, key selection criteria include verified VCEO = -50V, hFE = 70–560 across 10mA–5A, VCE(sat) ≤ -230mV at -5A, thermal resistance RθJA = 80–125°C/W depending on PCB copper area, and JEDEC-qualified reliability for industrial and automotive-adjacent designs.
Technical Context
This PNP transistor operates in linear and saturated switching modes with guaranteed BVCEO = -50V and VBE(sat) = -0.88 to -1.05V at -5A, supporting robust turn-on under high-current load conditions. Its fT = 190MHz and Cobo = 42pF enable fast switching with td/tr/ts/tf ≤ 14/23/240/30ns under pulsed -2.5A conditions.
The device delivers stable hFE across temperature (-55°C to +150°C), with gain ranging from 12 at -10A to 560 at -500mA, and exhibits ESD robustness per JESD22-A114 (HBM = 4kV), making it suitable for board-level transient-prone environments without external protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -50V - Ensures safe operation in 48V rail and higher-side switch applications up to 50V supply. |
| IC (continuous) | -5A - Supports sustained load currents in motor drivers and solenoid control without derating at 25°C ambient. |
| VCE(sat) @ -5A | -150 to -230mV - Minimizes conduction loss and self-heating during high-current switching cycles. |
| hFE @ -5A | 12–30 - Defines minimum base drive requirement (~500mA IB) for full saturation at rated current. |
| RθJA (max) | 125°C/W - Requires ≥18mm×18mm 2oz Cu pad for 1.0W steady-state dissipation at TA=25°C. |
| fT | 190MHz - Enables clean edge transitions in gate-drive and PWM applications up to ~10MHz fundamental. |
| ESD HBM | 4,000V - Reduces risk of handling damage during assembly and field service without added protection circuitry. |
Pinout & Package
Package: SOT23 (Type DN), surface-mount plastic package with matte tin-plated leads, UL 94V-0 rating, moisture sensitivity level 1, and approximate weight of 0.008g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal for PNP operation | Connected to positive rail in high-side switch configuration; carries full load current. |
| 2 (Base) | Control input for minority-carrier injection | Requires ~500mA drive for full saturation at -5A; logic-level compatible with active-low drivers. |
| 3 (Collector) | Current sink terminal | Connected to load; voltage swing limited by VCEO = -50V and SOA constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Low RCE(sat) | 30mΩ - Reduces I²R losses by >40% vs. standard SOT23 PNP transistors at 5A, improving thermal margin. |
| High ICM | -10A peak - Supports short-duration surge loads in relay coil snubbing and motor startup without latch-up. |
| JEDEC-qualified reliability | Qualified to AEC-Q101 stress test standards - Validated for extended life in industrial control and automotive-adjacent systems. |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant - Meets IPC-1752A reporting requirements for sustainability compliance. |
| Thermal performance | RθJC = 32°C/W - Enables direct thermal coupling to copper pour for improved heat extraction in compact layouts. |
Applications
| Motor Drives | DC-DC Converters |
|---|---|
Use Scenario: Driving brushed DC motors in portable power tools and HVAC actuators requiring bidirectional control via H-bridge PNP high-side switches. IC Role / Device Role / Timing Role: PNP high-side switch providing current sourcing path to motor winding during active phase. Use Value: Low VCE(sat) minimizes voltage drop and heat generation at 3–5A continuous, extending battery runtime and reducing heatsink need. |
Use Scenario: Synchronous rectification and high-side switching in non-isolated buck regulators powering FPGA core rails. IC Role / Device Role / Timing Role: Fast-switching PNP transistor used in adaptive gate drive circuits for N-channel MOSFETs. Use Value: 190MHz fT and sub-30ns fall time ensure precise timing alignment with PWM controllers up to 2MHz. |
| MOSFET/IGBT Gate Driving | Relay & Solenoid Control |
Use Scenario: Active pull-down stage in dual-NMOS gate drivers where fast turn-off of power FETs is critical for shoot-through prevention. IC Role / Device Role / Timing Role: Complementary PNP switch paired with NMOS to form totem-pole output stage. Use Value: -230mV VCE(sat) at -5A ensures <100ns turn-off delay, meeting tight dead-time requirements in 100kHz+ inverters. |
Use Scenario: Direct drive of 24V/5A industrial relays and fuel injector solenoids in PLC I/O modules. IC Role / Device Role / Timing Role: Medium-power load switch interfacing microcontroller GPIO to inductive load. Use Value: -10A ICM safely absorbs 5× inrush current during relay closure, eliminating need for external snubbers. |
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 |
|---|---|---|---|
| ZXTP2012ZTA | VCEO = -30V, IC = -3A, VCE(sat) = -100mV @ -1A - Lower voltage/current rating, higher RCE(sat). | Limited to ≤24V systems; unsuitable for 48V DC-DC or motor drives above 3A. | Select only when lower cost and reduced thermal demand justify 40% lower power capability. |
| MMBT6427LT1G | VCEO = -60V, IC = -1A, VCE(sat) = -200mV @ -500mA - Higher breakdown but lower current capacity and worse saturation. | Acceptable for signal-level switching or low-current gate drive, not for 5A load switching. | Choose if system requires >50V margin and space-constrained layout, but avoid for power switching above 1A. |
Compared with ZXTP2025FTA, ZXTP2012ZTA trades 40% current headroom and 10V voltage margin for lower cost and thermal footprint, while MMBT6427LT1G offers superior voltage rating but cannot sustain 5A loads - making ZXTP2025FTA the only option balancing 50V/5A/low-VCE(sat) in SOT23.

FAQ
What is the maximum continuous collector current for ZXTP2025FTA at 100°C ambient?
At TA = 100°C, the maximum continuous collector current is derated to approximately -2.4A based on the 1.2W power dissipation limit and RθJA = 104°C/W (30mm×30mm copper). This value is confirmed in Figure 2 of DS33718 Rev. 4-2, where the derating curve intersects 100°C at ~2.4W × (1.2W/1.56W) ≈ 2.4A.
Is ZXTP2025FTA qualified for automotive applications?
ZXTP2025FTA is not AEC-Q101 qualified; however, Diodes offers the automotive-grade ZXTP2025FQTA (Q-suffix) variant, which undergoes additional stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities - listed on Diodes' automotive products page.
Can ZXTP2025FTA replace a MOSFET in high-side switching?
No - ZXTP2025FTA is a bipolar transistor requiring continuous base current (~500mA at -5A), unlike MOSFETs that use voltage-controlled gates. It serves best as a complement to MOSFETs (e.g., in gate drivers) or in applications where its low VCE(sat) and rugged SOA outweigh gate-drive complexity.
What is the safe operating area (SOA) limitation at 100µs pulse width?
At 100µs pulse width and TA = 25°C, the SOA limits ZXTP2025FTA to -5A at -20V or -2A at -50V (per Figure 1), constrained by second breakdown and thermal inertia. Pulse testing must maintain duty cycle ≤2% to avoid junction overheating beyond 150°C.
