Product details
Overview
DXTN07045DFG-7 from Diodes Incorporated is a 45V NPN medium-power high-gain transistor in PowerDI3333-8 package, rated for 3A continuous collector current, with hFE > 400 at 1A and VCE(SAT) < 300mV at 1A. It serves as a load switch or gate driver in industrial power management systems operating up to +175°C.
For engineers reviewing the DXTN07045DFG-7 datasheet, DXTN07045DFG-7 pinout, DXTN07045DFG-7 application, or DXTN07045DFG-7 equivalent, key selection criteria include thermal resistance (RθJL = 8.5°C/W), wettable flank for AOI, ±175°C operation, and IC/IB = 100 saturation performance.
Technical Context
This NPN bipolar junction transistor features a robust silicon die optimized for linear and switching operation in high-temperature environments. Its BVCEO = 45V and VEBO = 7V support stable biasing in regulator feedback paths and gate-drive circuits where emitter-referenced control is required.
The device uses a thermally enhanced PowerDI3333-8 package with exposed collector tab for low RθJL (8.5°C/W) and supports pulsed SOA up to 6A with defined derating curves. Junction-to-lead thermal path enables direct PCB copper area coupling for sustained 3A DC conduction without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO / VCEO | 45V - Supports 36V nominal bus designs with 25% margin against transients. |
| IC (Continuous) | 3A - Enables direct drive of MOSFET gates or small solenoids without external buffering. |
| hFE @ 1A | 400–780 - Allows low-base-current control (IB = 2.5mA typical) for efficient drive-stage design. |
| VCE(SAT) @ 1A | 140–300mV - Limits conduction loss to ≤300mW at full load, reducing thermal burden. |
| RθJL | 8.5°C/W - Permits 2.1W dissipation on 25mm×25mm 2oz copper, enabling compact heatsinking. |
| TJ Range | −55°C to +175°C - Qualified for under-hood automotive, industrial motor controls, and enclosed power supplies. |
| fT | 150MHz - Sufficient for fast-switching gate drive (tON = 33ns, tOFF = 1300ns) in PWM circuits. |
Pinout & Package
Package: PowerDI3333-8 (SWP, Type UX), surface-mount, thermally enhanced with exposed collector tab and wettable flank terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitting terminal for majority carriers | Connected to ground or low-side reference; forms common-emitter configuration base for gain. |
| Pins 2–4 (Collector) | Main current-carrying terminal | Exposed metal tab - must be soldered to large copper pour for thermal conduction and current handling. |
| Pins 5–7 (Base) | Control input for minority carrier injection | Three parallel bond wires reduce base resistance; enables fast turn-on with low IB drive. |
| Pin 8 (Emitter) | Second emitter connection | Redundant emitter bond improves current sharing and reduces package inductance in high-di/dt switching. |
Key Features
| Feature | Design Value |
|---|---|
| Wettable flank leads | Enables automated optical inspection (AOI) of solder fillets on all four side terminals without X-ray. |
| +175°C rated operation | Validated junction temperature range allows deployment in engine-control modules and sealed industrial enclosures. |
| Low RθJL (8.5°C/W) | Direct thermal path from die to PCB copper reduces thermal bottleneck versus standard SOT-223 or TO-252. |
| High hFE at 3A | Minimum hFE = 50 ensures usable gain even at maximum rated current, supporting stable linear regulation. |
| Lead-free & green compliant | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) meets IPC-1752A Class 2 requirements. |
Applications
| Load Switch | Linear Regulator Pass Element |
|---|---|
Use Scenario: High-side switching of 24V/2A industrial sensors with reverse-polarity protection. IC Role / Device Role / Timing Role: NPN configured as emitter-follower to deliver regulated output while absorbing reverse current. Use Value: VCE(SAT) ≤300mV at 2A limits dropout to <0.3V and self-heating to <600mW on 25mm² copper. | Use Scenario: Adjustable 5V/1.5A linear regulator for FPGA core supply with thermal foldback. IC Role / Device Role / Timing Role: Pass transistor controlled by error amplifier; operates in active region with fixed VBE bias. Use Value: hFE ≥400 at 1.5A enables <4mA base drive, minimizing quiescent current in feedback loop. |
| MOSFET Gate Driver | IGBT Base Drive Amplifier |
Use Scenario: Low-side gate driver for 100V SiC MOSFET in 48V DC-DC converter half-bridge. IC Role / Device Role / Timing Role: Fast-switching NPN stage amplifying microcontroller GPIO to deliver 500mA peak gate current. Use Value: tON = 33ns and fT = 150MHz ensure <100ns total propagation delay for 500kHz PWM operation. | Use Scenario: Darlington pre-driver for 600V IGBT in HVAC inverter output stage. IC Role / Device Role / Timing Role: Medium-power buffer between optocoupler output and IGBT base, providing current gain and voltage isolation. Use Value: BVCEO = 45V and TJ = +175°C rating allow reliable operation adjacent to high-loss IGBT modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN07045F | Same die, identical specs, but in SOT-89-3 package with single emitter lead and no wettable flank. | Lacks AOI capability and has higher RθJA (120°C/W); unsuitable for high-density automated assembly. | Select only if legacy SOT-89 footprint compatibility is mandatory and thermal margin exceeds 40°C. |
| DMT3007LPSQ-13 | 30V-rated N-channel MOSFET (not BJT); RDS(on) = 12mΩ at 4.5V, Qg = 11nC; no hFE or VBE dependency. | Replaces BJT with voltage-controlled switch; eliminates base drive complexity but requires level-shifting for high-side use. | Prefer for new designs requiring zero gate current, lower conduction loss, and faster switching above 100kHz. |
Compared with ZXTN07045F and DMT3007LPSQ-13, DXTN07045DFG-7 uniquely combines wettable flank AOI support, ultra-low RθJL, and guaranteed hFE > 400 at 3A-making it optimal for space-constrained, thermally demanding BJT-based gate drives and regulators where manufacturability and thermal reliability are prioritized over raw speed.

FAQ
What is the maximum safe operating temperature for DXTN07045DFG-7 in continuous conduction?
The device is rated for junction temperatures from −55°C to +175°C. Under continuous 3A DC operation with 25mm×25mm 2oz copper, its thermal resistance RθJA is 65°C/W, allowing ambient temperatures up to +125°C before reaching TJ = 175°C - verified per JEDEC JESD51-2 and JESD51-14 standards.
Does DXTN07045DFG-7 support lead-free reflow profiles per IPC-J-STD-020?
Yes - it is rated Moisture Sensitivity Level 1 (MSL-1), meaning it can withstand unlimited floor life and standard Pb-free reflow profiles (peak 260°C, 30 seconds max) without baking. The matte tin finish meets MIL-STD-202 Method 208 for solderability.
Can DXTN07045DFG-7 be used in avalanche mode?
No - the datasheet does not specify avalanche energy rating (EAS) or ruggedness testing. Its absolute maximum ratings define safe operation only within the SOA curve; operation beyond VCEO = 45V risks irreversible breakdown. Use clamping diodes or snubbers for inductive load switching.
How does the dual-emitter configuration affect PCB layout?
The two emitter pins (1 and 8) must be routed with equal-length, low-inductance traces to a common ground plane. Unequal routing introduces asymmetry in current sharing and increases switching oscillation risk. Recommended layout uses symmetric copper pours and avoids vias between pins 1 and 8.
