Product details
Overview
ZXTP2009ZQTA from Diodes Incorporated is a 40V PNP bipolar junction transistor (BJT) optimized for automotive-grade power switching, delivering -5.5A continuous collector current, < -60mV saturation voltage at -1A, and 29mΩ equivalent on-resistance at full rated current. It operates in SOT89 package and is AEC-Q101 qualified for DC-DC converters, MOSFET gate drivers, and motor control circuits.
For engineers reviewing the ZXTP2009ZQTA datasheet, ZXTP2009ZQTA pinout, ZXTP2009ZQTA application, or ZXTP2009ZQTA equivalent, key selection criteria include its low VCE(sat) performance under high-current drive, thermal resistance of 42°C/W with 25mm×25mm copper, and AEC-Q101 qualification for automotive power stage design.
Technical Context
This PNP BJT features a robust breakdown rating of -50V VCBO and -40V VCEO, enabling reliable operation in 36V automotive systems and industrial 40V rail applications. Its fT of 152MHz supports fast switching in gate driver and PWM circuits.
The device exhibits strong current gain linearity-hFE = 175 at -5.5A-and maintains stable VBE(sat) (-900mV typ.) and VCE(sat) (-60mV max @ -1A) across -55°C to +150°C, supporting wide-temperature automotive deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VCEO | -40V - Withstands 36V automotive battery transients without breakdown |
| IC (cont.) | -5.5A - Supports high-current load switching in power stages |
| VCE(sat) max | -60mV @ -1A - Minimizes conduction loss and self-heating in linear/switching modes |
| RSAT | 29mΩ @ -5.5A - Enables low-loss operation comparable to discrete power MOSFETs |
| hFE | 175 @ -5.5A - Ensures sufficient base drive efficiency for low-power controller interfacing |
| fT | 152MHz - Supports fast turn-on/turn-off in gate driver and PWM applications |
| RθJA | 42°C/W (25mm×25mm Cu) - Allows >2W dissipation at 85°C ambient with standard PCB layout |
Pinout & Package
Package: SOT89 - Surface-mount plastic package with exposed collector tab for thermal enhancement and mechanical stability; UL 94V-0 rated, 0.05g weight, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Emitter (E) | Current source terminal | Connected to higher potential rail; carries full load current into external load |
| Base (B) | Control input | Receives negative current to saturate; requires ~550mA drive for full -5.5A conduction |
| Collector (C) | Power output terminal | Internally connected to exposed metal tab; must be thermally anchored to PCB copper for RθJC = 25°C/W |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive power modules requiring PPAP documentation and IATF 16949 manufacturing |

Applications
| DC-DC Converters | MOSFET Gate Drivers |
|---|---|
Use Scenario: High-efficiency synchronous buck converter output stage in automotive body control modules. IC Role / Device Role / Timing Role: PNP switch controlling high-side N-channel MOSFET gate via charge pump or level-shifted drive. Use Value: Low VCE(sat) minimizes gate drive loss; AEC-Q101 ensures reliability over 15-year vehicle lifetime. |
Use Scenario: Active pull-down stage in half-bridge gate driver ICs for BLDC motor inverters. IC Role / Device Role / Timing Role: Fast-turn-off switch sinking gate current from high-side MOSFET during dead-time control. Use Value: 152MHz fT and 325ns storage time enable sub-100ns turn-off-reducing shoot-through risk. |
| Charging Circuits | Motor Controls |

IC Role / Device Role / Timing Role: Low-loss freewheeling path during PWM off-time in automotive window lift or seat actuator drives. Use Value: -40V VCEO withstands inductive kickback up to 36V; -55°C to +150°C operation covers under-hood environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2012ZQTA | -60V VCEO, -4A IC, higher VCE(sat) (-100mV @ -1A) | Better voltage margin but lower current capacity and higher conduction loss | Select when system transients exceed 40V but load current remains ≤4A |
| DMT3009LSDQ-7 | N-channel 30V Trench MOSFET, RDS(on) = 12mΩ, logic-level gate | Lower on-resistance but requires gate drive voltage >VGS(th); no inherent polarity inversion | Prefer for low-voltage, high-efficiency switching where gate drive circuitry supports N-MOS topology |
Compared with ZXTP2009ZQTA, ZXTP2012ZQTA trades current capability for higher voltage safety margin, while DMT3009LSDQ-7 offers lower RDS(on) but introduces gate drive complexity and lacks native PNP functionality for level-shifting or high-side sourcing.

FAQ
What is the maximum safe operating temperature for ZXTP2009ZQTA?
The device is rated for junction temperatures from -55°C to +150°C. With RθJA = 42°C/W on 25mm×25mm copper, it sustains 2.1W dissipation at 85°C ambient-enough for most automotive under-dash applications without forced cooling.
Is ZXTP2009ZQTA pin-compatible with other SOT89 PNP transistors?
No-pin assignment (E-B-C) is fixed per SOT89 standard, but electrical characteristics differ significantly. Substitution requires verification of VCEO, IC, VCE(sat), and hFE curves; ZXTP2009ZQTA's 29mΩ RSAT and AEC-Q101 status are not matched by generic SOT89 PNPs.
Does ZXTP2009ZQTA require a heatsink in typical applications?
Not necessarily: with proper 25mm×25mm 1oz copper pad, it achieves RθJA = 42°C/W. At 1.5W dissipation and 85°C ambient, junction temperature reaches ~148°C-within spec. Heatsinking is only needed for >2W continuous loads or elevated ambient conditions.
How does the -15A peak pulse rating translate to real-world use?
The -15A ICM rating applies to single pulses ≤300µs with ≤2% duty cycle. It supports brief overload events like motor stall currents, capacitor inrush, or fault clearing-provided PCB layout maintains low-inductance paths and thermal mass prevents cumulative heating.
