Product details
Overview
DXTP22040CFGQ from Diodes Incorporated is a 40V PNP bipolar junction transistor in PowerDI3333-8 package, rated for -2A continuous collector current and -225mV VCE(sat) at -1A, with AEC-Q101 qualification for automotive high-side switching and motor drive applications.
For engineers reviewing the DXTP22040CFGQ datasheet, DXTP22040CFGQ pinout, DXTP22040CFGQ application, or DXTP22040CFGQ equivalent, key selection criteria include low saturation voltage under high-current switching, thermal performance up to +175°C, wettable flank for automated optical inspection, and compliance with automotive PPAP and IATF16949 manufacturing requirements.
Technical Context
This PNP transistor operates as a high-side switch with verified VCEO = -40V, VCE(sat) ≤ -225mV @ -1A/-100mA, and hFE ≥ 200 at -100mA. Its PowerDI3333-8 package delivers RθJL = 11°C/W and supports 3.4W power dissipation on 50mm × 50mm 2oz copper.
It features complementary NPN pairing (DXTN22040CFGQ), JEDEC Class 3A HBM ESD rating (4kV), and guaranteed operation from -55°C to +175°C - enabling use in under-hood automotive modules and industrial motor controllers where thermal margin and reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -40V - Ensures safe blocking of 36V automotive supply transients without breakdown |
| IC (cont.) | -2A - Supports sustained load switching in 12V/24V motor drivers and supply rails |
| VCE(sat) | < -225mV @ -1A/-100mA - Minimizes conduction loss and self-heating during active switching |
| TJ max | +175°C - Enables placement near heat sources (e.g., engine control units) without derating |
| RθJL | 11°C/W - Provides direct thermal path from junction to PCB via collector tab for efficient heat transfer |
| ESD HBM | 4,000V - Meets robustness requirements for assembly and in-system handling in automotive production |
| Package | PowerDI3333-8 - Surface-mount, wettable flank design for AOI-compatible solder joint verification |
Pinout & Package
DXTP22040CFGQ uses the PowerDI3333-8 (SWP, Type UX) thermally enhanced 8-pin package with exposed collector tab for low thermal resistance. Pin 1 is marked on top view; bottom view shows wettable flank terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Collector (common tab) | Electrically connected internal collector leads; soldered to large copper pour for thermal management |
| 5 | Base | Control input for turn-on/turn-off; requires -100mA base drive for full -1A saturation |
| 6, 7, 8 | Emitter | Current return path; electrically isolated from collector tab; connects to load ground reference |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTOL, and ESD per JESD22 |
| Wettable flank terminals | Enables automated optical inspection (AOI) of solder fillets on all side pins for zero-defect manufacturing |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and "Green" definition: Br+Cl <1500ppm, Sb <1000ppm |
| High-temperature operation | Rated from -55°C to +175°C with no derating required up to maximum junction temperature |
| Complementary NPN pair | DXTN22040CFGQ shares identical package, ratings, and thermal performance for balanced H-bridge designs |

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 |
|---|---|---|---|
| ZXTN22040CFH | NPN complement (same VCEO, IC, package); not PNP - requires circuit topology change | Suitable only in low-side configurations; incompatible with existing high-side schematics | Select only when redesigning for NPN-driven loads or complementary H-bridge layouts |
| DMT3004LPSQ-13 | P-channel MOSFET (30V, -4.5A, RDS(on) = 32mΩ); gate-driven, no base current needed | Lower drive complexity but higher VGS(th) sensitivity; less robust against gate overvoltage | Prefer for new designs prioritizing drive simplicity; avoid if legacy BJT bias networks exist |
Compared with ZXTN22040CFH and DMT3004LPSQ-13, DXTP22040CFGQ offers direct drop-in replacement in existing PNP high-side circuits, guaranteed AEC-Q101 qualification, and superior thermal stability at elevated ambient temperatures - making it optimal for retrofitting or maintaining automotive production continuity.

FAQ
Is DXTP22040CFGQ pin-compatible with DXTN22040CFGQ?
No - DXTP22040CFGQ is a PNP transistor while DXTN22040CFGQ is its complementary NPN counterpart. They share identical PowerDI3333-8 package dimensions and thermal characteristics but have opposite polarity and reversed pin functions (collector/emitter swapped). Direct substitution would invert circuit behavior and cause failure.
What is the minimum base current required to saturate DXTP22040CFGQ at 2A collector current?
Per datasheet Figure 4 and electrical specs, saturation at IC = -2A requires IB = -200mA (hFE ≥ 10 at this condition). For reliable design margin, use IB ≥ -250mA with appropriate base resistor sizing to ensure VBE(sat) ≈ -0.88V and VCE(sat) ≤ -350mV.
Can DXTP22040CFGQ be used in non-automotive industrial applications?
Yes - its -55°C to +175°C operating range, 4kV HBM ESD rating, and IATF16949-manufactured process make it fully suitable for industrial motor drives, power supplies, and HVAC controls. AEC-Q101 qualification adds reliability assurance but does not restrict usage to automotive end equipment.
Does the PowerDI3333-8 package require special PCB layout considerations?
Yes - the exposed collector tab must connect to a minimum 25mm × 25mm 2oz copper area for rated 2.3W dissipation. Thermal vias under the tab (≥6×0.3mm diameter) are recommended. Suggested pad layout and footprint dimensions are published in Diodes' package outline document PN-0000112 (PowerDI3333-8 SWP).
