Product details

Overview

ZXTP2014GTA from Diodes Incorporated is a 140V PNP medium-power low-saturation transistor in SOT223 package, rated for -4A continuous collector current and -10A peak pulse current, with V_CE(sat) < -120mV at -1A, R_SAT = 92mΩ, and AEC-Q101 qualification-used in automotive power switching, industrial DC-DC converters, and high-voltage load control circuits.

For engineers reviewing the ZXTP2014GTA datasheet, ZXTP2014GTA pinout, ZXTP2014GTA application, or ZXTP2014GTA equivalent, key selection criteria include breakdown voltage (BV_CEO = -140V), saturation resistance (92mΩ), thermal resistance (R_θJA = 41.7°C/W on 52mm × 52mm 2oz Cu), and AEC-Q101 reliability compliance for automotive-grade designs.

Technical Context

This PNP bipolar junction transistor operates as a high-voltage, medium-current switch with specified h_FE up to 100 at -10A, enabling stable gain hold-up under heavy load conditions. Its low V_CE(sat) and R_SAT minimize conduction losses in linear and switching modes.

The device features robust ESD protection (8kV HBM), operates across -55°C to +150°C, and uses a green, halogen-free molding compound compliant with UL 94V-0-designed for thermally demanding, safety-critical automotive and industrial environments where high BV_CEO and low thermal resistance are essential.

Key Specifications

Parameter	Value and Actual Design Meaning
BV_CEO	-140 V - supports high-side switching in 48V+ automotive systems without breakdown risk
I_C (continuous)	-4 A - enables direct drive of solenoids, relays, and motor windings in industrial controls
V_CE(sat)	< -120 mV @ -1A - reduces power loss to <120mW at rated current, easing thermal design
R_SAT	92 mΩ - provides predictable on-resistance for precise current sensing and loss modeling
h_FE	45–100 @ -3A - ensures sufficient current gain for base-drive efficiency in high-current switching
R_θJA	41.7 °C/W - requires only modest copper area (52mm × 52mm 2oz) for 3W dissipation at ambient
ESD HBM	8,000 V - withstands handling and board-level transients without gate oxide damage

Pinout & Package

Package: SOT223, surface-mount, 3-terminal plastic case with exposed collector tab for thermal enhancement and mechanical anchoring. Molded compound meets UL 94V-0 and is halogen/antimony-free.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main current path output terminal	Exposed metal tab serves as primary heat sink interface and must be soldered to large copper pour
Emitter	Current source node for PNP operation	Connected to higher potential rail; defines reference for base-emitter biasing
Base	Control input for transistor turn-on/off	Requires current-limited drive (e.g., 100mA max) to achieve full saturation at -1A I_C

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive power electronics per stress test requirements including temperature cycling and HTRB
Low V_CE(sat) & R_SAT	Enables <120mW conduction loss at -1A, reducing heatsink size and system footprint
High BV_CEO (-140V)	Supports 48V battery systems with margin against load-dump transients up to ±120V
Green, RoHS-compliant construction	Halogen-free (<900ppm Br/Cl), antimony-free, and lead-free-meets global environmental compliance mandates

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-voltage switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZXTP2029GTA	BV_CEO = -200V, I_C = -3A, V_CE(sat) = -150mV @ -1A	Higher voltage margin but lower current rating and higher saturation loss	Select when >160V system transients dominate over continuous current demand
MJD2955T4G	BV_CEO = -70V, I_C = -10A, V_CE(sat) = -1.8V @ -5A	Higher current capacity but insufficient voltage rating for 48V+ systems	Choose only for 24V or lower industrial applications requiring >5A continuous current

Compared with ZXTP2014GTA, ZXTP2029GTA trades current capability for enhanced voltage robustness, while MJD2955T4G offers higher current but fails to meet 48V+ automotive transient requirements-making ZXTP2014GTA the optimal balance of voltage, current, and loss performance in AEC-Q101-compliant designs.

FAQ

What is the maximum safe operating voltage for ZXTP2014GTA in continuous DC applications?

The ZXTP2014GTA has a guaranteed minimum BV_CEO of -140V, making it suitable for continuous DC operation up to -130V with appropriate derating. For automotive 48V systems subject to ISO 7637-2 load dump transients (up to ±120V), this provides adequate margin without external clamping.

Can ZXTP2014GTA be used in parallel for higher current handling?

No-this PNP BJT lacks inherent current-sharing characteristics due to negative temperature coefficient of V_CE(sat). Parallel operation risks thermal runaway unless actively balanced with emitter resistors and matched devices. For >4A, use a single higher-rated device or MOSFET-based solution.

Is the SOT223 package's exposed collector tab electrically isolated from other pins?

No-the collector tab is electrically connected to the collector terminal and must be treated as a live high-current node. It is not insulated; PCB layout must maintain required creepage and clearance distances (per IPC-2221) between the tab and adjacent traces or planes.

Does ZXTP2014GTA require a base resistor when driven directly from a 3.3V microcontroller GPIO?

Yes-a series base resistor is mandatory. With V_BE(sat) ≈ -940mV and typical I_B = -100mA for -1A I_C, a 3.3V GPIO must limit base current to avoid exceeding I_BM. A 22Ω resistor yields ~105mA base drive, ensuring saturation while staying within safe SOA limits.
