Product details
Overview
DXTP07040CFGQ-7 from Diodes Incorporated is a 40V PNP bipolar junction transistor in PowerDI3333-8 package, rated for -3A continuous collector current, -400mV VCE(sat) at -1A, minimum hFE of 200, and operation up to +175°C. It serves as a high-side switch or gate driver in automotive power management systems requiring low saturation voltage and AEC-Q101 reliability.
For engineers reviewing the DXTP07040CFGQ-7 datasheet, DXTP07040CFGQ-7 pinout, DXTP07040CFGQ-7 application, or DXTP07040CFGQ-7 equivalent, key selection criteria include verified VCE(sat) ≤ -400mV @ -1A, hFE ≥ 200 at -1A/-2V, thermal resistance RθJL = 8.5°C/W, wettable flank compatibility for AOI, and AEC-Q101 qualification status.
Technical Context
This PNP transistor operates with a guaranteed BVCEO of -40V and supports peak pulse current up to -6A. Its low VCE(sat) enables efficient high-side switching in LDOs and gate-drive circuits where voltage headroom is constrained.
The device features a thermally optimized PowerDI3333-8 package with RθJL = 8.5°C/W and wettable flanks for automated optical inspection. It is fully RoHS-compliant, halogen/antimony-free, and qualified to AEC-Q101 for automotive underhood applications.

|---|---|
|
Use Scenario: Controlling 12V/24V loads (e.g., fuel pumps, solenoids) directly from MCU GPIO via level-shifting base drive. IC Role / Device Role / Timing Role: PNP high-side switch providing reverse-polarity protection and fast turn-off via base pull-up. Use Value: VCE(sat) ≤ -400mV ensures <1.2W loss at -3A, reducing heatsink requirements in compact modules. |
Use Scenario: Pass element in automotive LDOs delivering stable 5V/3.3V rails from noisy battery inputs. IC Role / Device Role / Timing Role: Series pass transistor regulating output by modulating base current in linear mode. Use Value: High hFE (≥200) allows low-base-drive current, minimizing quiescent consumption in always-on domains. |
| MOSFET Gate Driver | Engine Control Unit Output Stage |
|
Use Scenario: Driving N-channel MOSFET gates in half-bridge motor drivers where bootstrap limitations exist. IC Role / Device Role / Timing Role: Active pull-down stage complementing high-side driver ICs to ensure fast gate discharge. Use Value: tOFF ≤ 600ns enables >100kHz switching in BLDC controllers without shoot-through risk. |
Use Scenario: Output stage for injector or ignition coil drivers in gasoline/diesel ECUs operating at 125°C ambient. IC Role / Device Role / Timing Role: Final power switch interfacing microcontroller PWM with inductive loads. Use Value: +175°C TJ rating and AEC-Q101 qualification ensure functional safety compliance per ISO 26262 ASIL-B. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-current switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN25050DFH | VCEO = -50V, IC = -5A, but VCE(sat) = -500mV @ -1A; SOT-23-3 package. | Lacks wettable flanks and AEC-Q101 qualification; unsuitable for automotive production. | Select only for non-automotive prototypes where higher voltage margin outweighs thermal penalty. |
| DMT3005LPSQ-7 | P-channel MOSFET, RDS(on) = 45mΩ @ VGS = -10V; no gate drive current required. | Requires negative gate bias for full enhancement; incompatible with simple BJT drive topologies. | Prefer when gate drive circuitry is already designed for MOSFET logic-level control and lower static loss is critical. |
Compared with ZXTN25050DFH and DMT3005LPSQ-7, DXTP07040CFGQ-7 uniquely combines AEC-Q101 qualification, wettable flanks, sub-400mV saturation voltage, and PowerDI3333-8 thermal performance-making it the only drop-in solution for production automotive high-side switches requiring AOI and +175°C operation.

FAQ
What is the maximum allowable PCB copper area for optimal thermal performance?
The datasheet specifies 3.1W power dissipation when mounted on 50mm × 50mm 2oz copper. Using less copper reduces thermal capability proportionally: 25mm × 25mm yields 2.1W, while standard FR4 yields only 0.9W. Thermal relief patterns must preserve direct thermal path from collector tab to copper plane.
Is the PowerDI3333-8 package compatible with standard reflow profiles?
Yes-PowerDI3333-8 is rated Moisture Sensitivity Level 1 per J-STD-020 and supports IPC/JEDEC J-STD-020D.2 lead-free reflow profiles with peak temperatures up to 260°C. The matte tin finish ensures reliable solderability without pre-baking for MSL-1 devices.
Can DXTP07040CFGQ-7 replace NPN transistors in existing designs?
No-it is a PNP device with inverted polarity and complementary drive requirements. Replacing an NPN requires redesigning base drive (e.g., adding level shifters or inverters) and verifying VCE(sat), hFE, and switching timing against system specs. Direct substitution is not electrically feasible.
Does the "2G5" marking indicate RoHS or AEC-Q101 compliance?
"2G5" is the product type code per Diodes' marking standard-not a compliance indicator. RoHS and AEC-Q101 status are confirmed by the full part number suffix "Q" (e.g., DXTP07040CFGQ-7) and documented in DS41047 Rev. 1–2, Section 1 and Notes 1–4.
