Product details
Overview
ZXTP2014ZQTA from Diodes Incorporated is a 140V PNP bipolar junction transistor (BJT) engineered for automotive-grade high-side switching, delivering -3A continuous collector current, -140V VCEO, and ultra-low saturation voltage of -37mV at IC = -0.1A/ IB = -5mA. It operates across -55°C to +150°C and is AEC-Q101 qualified for motor driving and SLIC applications.
For engineers reviewing the ZXTP2014ZQTA datasheet, ZXTP2014ZQTA pinout, ZXTP2014ZQTA application, or ZXTP2014ZQTA equivalent, key selection criteria include verified VCE(sat) performance at high IC, thermal resistance (RθJA = 83°C/W on 25mm × 25mm copper), and SOT89 package compatibility with high-power PCB layouts.
Technical Context
This PNP BJT employs epitaxial planar construction optimized for low-saturation operation in medium-power linear and switching modes. Its BVCEO = -140V and RSAT = 85mΩ @ IC = -3A enable robust high-voltage load control with minimal conduction loss.
The device features a transition frequency fT of 120MHz and hFE = 100–300 across IC = -10mA to -10A, supporting both analog amplification and fast-switching functions. ESD ratings meet JEDEC HBM Class 3A (4000V) and MM (400V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -140V - Withstands 140V reverse collector-emitter bias without breakdown, enabling use in 48V+ automotive power rails. |
| IC (cont.) | -3A - Supports continuous load currents up to 3A, suitable for driving solenoids, relays, and small motors. |
| VCE(sat) | -37mV @ IC = -0.1A/IB = -5mA - Minimizes power dissipation and self-heating during saturated switching. |
| RθJA | 83°C/W - Thermal resistance measured on 25mm × 25mm 1oz Cu PCB; defines maximum power derating slope (12mW/°C). |
| fT | 120MHz - Enables stable operation in high-frequency switching circuits up to ~10MHz practical bandwidth. |
| AEC-Q101 | Qualified - Validated for automotive temperature cycling, humidity, and mechanical stress per JESD22 standards. |
| Package | SOT89 - Thermally enhanced 3-pin surface-mount package with exposed collector tab for direct PCB heat sinking. |
Pinout & Package
Package: SOT89 - Molded plastic case with exposed collector tab (pin 2), rated for 1.5W dissipation on 25mm × 25mm copper and 2.1W on 50mm × 50mm copper. Moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Current source terminal | Connected to higher potential rail in high-side switch configuration; carries full load current. |
| Pin 2 (Collector) | Current sink terminal | Exposed metal tab - electrically connected to collector and serves as primary thermal path to PCB copper. |
| Pin 3 (Base) | Control input | Receives negative drive current (-300mA max) to saturate transistor; requires current-limiting resistor in series. |
Key Features
| Feature | Design Value |
|---|---|
| Low saturation resistance | RSAT = 85mΩ @ IC = -3A - Reduces conduction loss by >40% vs. standard PNP transistors in same package. |
| AEC-Q101 qualification | Validated for automotive underhood environments - ensures reliability over 15-year vehicle lifetime with thermal cycling and vibration. |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb) - meets EU ELV and OEM sustainability requirements. |
| High ESD immunity | HBM 4000V / MM 400V - Eliminates need for external ESD protection in board-level designs for industrial interfaces. |
Applications
| Motor Driving | Line Switching |
|---|---|
Use Scenario: Driving 12V/24V brushed DC motors in automotive seat adjusters and HVAC actuators. IC Role / Device Role / Timing Role: High-side PNP switch controlling motor direction and PWM speed via base current modulation. Use Value: -37mV VCE(sat) at low IC minimizes heat generation during idle hold; -140V rating supports load dump transients. |
Use Scenario: Power sequencing and isolation of auxiliary 12V/48V subsystems in ADAS domain controllers. IC Role / Device Role / Timing Role: Load switch enabling/disabling downstream rails with controlled turn-on slew rate. Use Value: Fast tON = 42ns and tOFF = 636ns support precise timing-critical power gating without shoot-through risk. |
| High Side Switches | Subscriber Line Interface Cards (SLIC) |
Use Scenario: Replacing discrete P-channel MOSFETs in cost-sensitive high-side power switches for industrial PLC I/O modules. IC Role / Device Role / Timing Role: Voltage-controlled current source regulating load current with fixed gain hFE = 225 @ IC = -1A. Use Value: SOT89 thermal performance enables 1.5W continuous operation without heatsink-reducing BOM count vs. TO-220 alternatives. |
Use Scenario: Overvoltage protection and ring detection circuitry in telecom SLICs for VoIP gateways and PBX systems. IC Role / Device Role / Timing Role: Current-limited high-voltage switch isolating subscriber line during fault conditions. Use Value: BVCBO = -180V withstands ±170V ringing voltages; low leakage ICBO < -0.5nA prevents false triggering in analog monitoring paths. |
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 |
|---|---|---|---|
| ZXTP2022ZQTA | VCEO = -200V, IC = -2A, VCE(sat) = -60mV @ IC = -2A - higher voltage rating but lower current capability. | Better suited for 60V+ telecom power supplies; less optimal for 3A motor loads due to reduced current headroom. | Select when system transient voltage exceeds 140V but peak load current remains ≤2A. |
| MJD2955T4G | VCEO = -70V, IC = -10A, VCE(sat) = -1.2V @ IC = -8A - lower voltage rating, higher current, significantly higher saturation voltage. | Acceptable for 24V industrial controls where thermal margin allows higher VCE(sat); not AEC-Q101 qualified. | Choose only for non-automotive applications requiring >3A continuous current and where 70V rating suffices. |
Compared with ZXTP2014ZQTA, ZXTP2022ZQTA trades current capacity for higher voltage robustness, while MJD2955T4G offers greater current handling at the expense of saturation loss and automotive compliance-making ZXTP2014ZQTA the optimal balance for 48V automotive high-side switching.

FAQ
What is the maximum safe operating temperature for ZXTP2014ZQTA?
The ZXTP2014ZQTA has an operating junction temperature range of -55°C to +150°C. Its thermal resistance RθJA is 83°C/W on a 25mm × 25mm 1oz copper PCB. To maintain TJ ≤ 150°C at 1.5W dissipation, ambient temperature must stay below 25.5°C - derating is required above that point per the 12mW/°C linear curve.
Can ZXTP2014ZQTA be used as a direct replacement for a P-channel MOSFET in high-side switching?
No - it is a bipolar transistor requiring continuous base current (e.g., -300mA at IC = -3A), unlike MOSFETs which are voltage-driven. However, its low VCE(sat) and SOT89 thermal design make it viable where gate drive complexity or cost outweighs the need for zero-gate-current operation.
Is the SOT89 package lead finish compatible with lead-free reflow soldering?
Yes - the terminals feature matte tin plating and are fully RoHS 3 compliant. They meet MIL-STD-202 Method 208 for solderability and are qualified for standard Pb-free reflow profiles (peak 260°C, 60-second duration) per J-STD-020 Level 1 moisture sensitivity.
Does ZXTP2014ZQTA require external base resistors in switching applications?
Yes - base current must be actively limited to avoid exceeding IB = -300mA absolute maximum. For IC = -3A and hFE = 100, a minimum base drive of -30mA is needed; typical designs use a 1kΩ resistor from microcontroller GPIO (3.3V/5V) to ensure safe saturation without overdriving.
