Product details
Overview
ZXTP2027FTA from Diodes Incorporated is a 60V, -4A PNP medium-power transistor in SOT23 package, featuring -60mV VCE(SAT) at -1A, 45mΩ RCE(SAT), and 1.2W power dissipation. It serves as a high-side switch for MOSFET/IGBT gate driving, motor control, and solenoid/relay actuation in industrial and automotive power interfaces.
For engineers reviewing the ZXTP2027FTA datasheet, ZXTP2027FTA pinout, ZXTP2027FTA application, or ZXTP2027FTA equivalent, key selection criteria include verified -60V VCEO, -4A continuous current capability, low saturation voltage under high-current drive conditions, and AEC-Q101 qualification for reliability-critical switching nodes.
Technical Context
This PNP bipolar junction transistor operates with a minimum DC current gain (hFE) of 80 at -4A and -2V VCE, supporting robust base-driven switching across -55°C to +150°C ambient. Its safe operating area (SOA) sustains -4A DC at -20V VCE with derated power above 25°C.
VCE(SAT) remains ≤ -95mV at -2A/-200mA drive, enabling efficient high-side switching with minimal conduction loss. Transition frequency fT of 165MHz supports fast turn-off in pulse-driven loads such as gate drivers and solenoids.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60V - Withstands 60V reverse collector-emitter voltage in open-base configuration, suitable for 48V system high-side switching. |
| IC (continuous) | -4A - Supports sustained load currents up to 4A, enabling direct drive of medium-power relays and small motors. |
| VCE(SAT) @ -1A | ≤ -60mV - Delivers low conduction loss at 1A, reducing thermal stress in compact SOT23 footprint. |
| RCE(SAT) | 45mΩ - Equivalent on-resistance enables predictable voltage drop modeling in high-side switch designs. |
| PD (max) | 1.2W - Achievable with 30mm × 30mm 2oz copper PCB pad, defining thermal layout requirements for stable operation. |
| fT | 165MHz - Enables sub-10ns turn-off times (tF = 21ns), critical for fast-switching gate driver stages. |
| AEC-Q101 | Qualified - Meets automotive-grade reliability standards for temperature cycling, HBM ESD (4kV), and mechanical robustness. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 0.008g mass, UL 94V-0 flammability rating, and matte tin-plated leads compliant with MIL-STD-202 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to positive rail in high-side switch configurations; carries full load current. |
| 2 (Base) | Control input | Receives negative base current to saturate transistor; requires current-limiting resistor in series. |
| 3 (Collector) | Load connection node | Connected to load (e.g., MOSFET gate, relay coil); pulled low during conduction to enable load activation. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(SAT) at high current | -60mV max at -1A ensures <60mW conduction loss per switch event, minimizing thermal rise in space-constrained layouts. |
| High peak pulse current | -10A ICM supports inrush current handling for solenoids and motor startup without secondary protection. |
| Thermal derating support | 104°C/W RθJA on 30mm × 30mm 2oz copper allows accurate junction temperature prediction up to 125°C ambient. |
| Complementary NPN pairing | ZXTN2018F provides matched performance for push-pull or H-bridge output stages requiring symmetrical drive. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-side switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2012ZTA | -40V VCEO, -3A IC, higher VCE(SAT) (-100mV @ -1A) | Limited to 24V systems; less margin for inductive flyback suppression | Select when lower voltage rating suffices and cost sensitivity outweighs thermal performance. |
| MMBT2907ALT1G | -60V VCEO, -0.6A IC, 350mW PD, no AEC-Q101 qualification | Not suitable for >0.6A continuous loads; lacks automotive reliability validation | Use only in non-automotive, low-current biasing or signal-level switching where qualification is not required. |
Compared with ZXTP2027FTA, ZXTP2012ZTA trades voltage headroom and saturation performance for cost, while MMBT2907ALT1G sacrifices current capacity and qualification for legacy compatibility-neither matches the 4A/AEC-Q101/low-VCE(SAT) combination essential for modern high-reliability power interface designs.

FAQ
What is the maximum allowable base current for ZXTP2027FTA?
The absolute maximum base current is -1A per the datasheet's Absolute Maximum Ratings table. However, typical design practice limits IB to -200mA for -4A collector current to maintain hFE ≥ 20 and avoid excessive base power dissipation. Exceeding -200mA does not improve saturation but increases thermal load on the base drive circuit.
Can ZXTP2027FTA be used in parallel for higher current handling?
No-this PNP transistor lacks inherent current-sharing characteristics due to negative temperature coefficient of VCE(SAT). Parallel operation causes thermal runaway unless actively balanced with individual emitter resistors and matched devices. The datasheet does not recommend or characterize parallel use, and AEC-Q101 qualification applies only to single-device operation.
Is ZXTP2027FTA compatible with lead-free reflow profiles?
Yes-ZXTP2027FTA is fully RoHS-compliant with matte tin-plated leads qualified to JEDEC J-STD-020 moisture sensitivity level 1. It supports standard lead-free reflow profiles up to 260°C peak temperature, with no pre-bake required, and meets MIL-STD-202 solderability testing.
How does the 1.2W power dissipation rating relate to PCB layout?
The 1.2W rating assumes mounting on a 30mm × 30mm 2oz copper pad per the datasheet Note 6. Reducing copper area increases thermal resistance: on 18mm × 18mm copper, PD drops to 1.0W (RθJA = 125°C/W). Layout must replicate the specified copper area to achieve rated power handling without exceeding 150°C junction temperature.
