Overview
DXTP07040CFG-7 from Diodes Incorporated is a 40V PNP bipolar junction transistor in PowerDI3333-8 package, rated for -3A continuous collector current and -400mV VCE(sat) at -1A, with minimum hFE of 200 at -1A and AEC-Q101 qualification. It serves as a high-side switch or gate driver in automotive power management and LDO regulators operating up to +175°C.
For engineers reviewing the DXTP07040CFG-7 datasheet, DXTP07040CFG-7 pinout, DXTP07040CFG-7 application, or DXTP07040CFG-7 equivalent, key selection criteria include verified VCE(sat) ≤ -400mV @ -1A, thermal resistance RθJL = 8.5°C/W, wettable flank terminals for AOI, and AEC-Q101 reliability validation for under-hood automotive use.
Technical Context
This PNP transistor features a rugged silicon die optimized for low-saturation switching in high-temperature environments. Its BVCEO = -40V and VBE(sat) = -0.8V @ -1A/-10mA support stable biasing in high-side configurations where emitter is tied to rail.
The PowerDI3333-8 package integrates a thermally efficient copper leadframe with wettable flanks and RθJL = 8.5°C/W, enabling direct heat transfer from junction to PCB via the collector tab-critical for sustained -3A operation without derating in compact layouts.
Key Specifications

|---|---|
| VCEO | -40V - Maximum allowable collector-emitter voltage before breakdown; defines safe operating range in high-side switch applications. |
| IC | -3A - Continuous DC collector current capacity; supports robust load driving without forced cooling in space-constrained designs. |
| VCE(sat) | < -400mV @ -1A/-10mA - Low saturation voltage minimizes conduction loss and self-heating during active switching. |
| hFE | 200 min @ -1A/-2V - Guaranteed DC current gain ensures reliable base drive sizing for predictable turn-on behavior. |
| RθJL | 8.5°C/W - Junction-to-leads thermal resistance enables efficient heat extraction through collector tab to PCB copper. |
| TJ max | +175°C - Maximum junction temperature rating allows deployment in engine compartment and industrial motor control environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2010ZTA | Higher VCEO (-60V), but higher VCE(sat) (-600mV @ -1A); SOT89 package with no wettable flanks. | Lacks AEC-Q101 qualification and thermal performance (RθJA = 125°C/W); unsuitable for automotive under-hood use. | Select only for non-automotive, lower-voltage industrial controls where cost outweighs thermal and reliability requirements. |
| DMT3005LKQ-7 | Same PowerDI3333-8 package and AEC-Q101 rating, but NPN polarity; VCE(sat) = -250mV @ -1A, hFE = 250 min. | Requires inverted circuit topology (low-side switch); incompatible with existing high-side schematics without redesign. | Use only when redesigning for low-side configuration or complementary pairing with DXTP07040CFG-7 in push-pull stages. |

FAQ
What is the maximum continuous collector current for DXTP07040CFG-7?
The maximum continuous collector current (IC) is -3A at TA = +25°C with appropriate PCB copper area. Derating applies above +25°C ambient: at +100°C, IC drops to approximately -1.8A based on RθJA = 65°C/W with 25mm × 25mm 2oz copper.
Does DXTP07040CFG-7 require a base resistor, and how is its value calculated?
Yes-a base resistor is required to limit base current. For -1A collector current and hFE = 200 min, minimum base current is -5mA. With VBE(sat) ≈ -0.8V and 3.3V GPIO drive, RB = (3.3V − 0.8V)/5mA = 500Ω. A 470Ω standard value ensures reliable saturation.
Can DXTP07040CFG-7 be used in a synchronous rectifier application?
No-it is a PNP bipolar transistor, not a MOSFET, and lacks the low RDS(on), fast reverse recovery, and gate-drive compatibility required for synchronous rectification. Its bipolar structure introduces storage time delays and higher conduction losses unsuitable for high-frequency rectifier topologies.
Is the PowerDI3333-8 package compatible with standard reflow profiles?
Yes-the PowerDI3333-8 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C, 60s above 217°C). The matte tin finish ensures reliable solderability without pre-baking for MSL-1 devices.
