Product details
Overview
DP0150ALP4-7 from Diodes Incorporated is a 50V PNP small-signal transistor in X2-DFN1006-3 package, rated for -100mA continuous collector current, -50V VCEO, and 400mW power dissipation (on minimum pad layout). It delivers high DC current gain (hFE = 200–400 at -2mA), low VCE(sat) (-150mV typ. at -100mA/-10mA), and 80MHz fT, serving as a compact switching or amplification element in space-constrained DC-DC bias networks and LED driver stages.
For engineers reviewing the DP0150ALP4-7 datasheet, DP0150ALP4-7 pinout, DP0150ALP4-7 application, or DP0150ALP4-7 equivalent, key selection criteria include verified PNP polarity, confirmed X2-DFN1006-3 thermal performance (RθJA = 310°C/W), validated ESD robustness (4kV HBM), and complementary NPN pairing with DN0150BLP4 for matched dual-transistor designs.
Technical Context
This PNP transistor operates with emitter-base forward bias and collector-base reverse bias in common-emitter configuration. Its -50V VCEO and -50V VCBO support rail-to-rail voltage handling in negative-supply logic interfaces and load-switching circuits up to -50V, while its -650mV to -950mV VBE(sat) range across -10mA to -50mA ensures predictable base drive requirements.
The device uses NiPdAu-plated terminals on a green molded plastic case (UL 94V-0), with moisture sensitivity level 1 and 0.4mm max height. Thermal resistance from junction to lead is 120°C/W, enabling direct heat sinking via the exposed collector pad - critical for stable operation under pulsed 200mA ICM conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -50V - Maximum allowable collector-emitter voltage before breakdown; defines safe operating range in negative-rail switching applications. |
| IC (cont.) | -100mA - Continuous collector current rating; sets maximum steady-state load current capability without derating. |
| PD | 400mW - Power dissipation on standard 1oz copper PCB; determines thermal margin in compact layouts without heatsinking. |
| hFE | 200–400 - DC current gain at VCE = -6V, IC = -2mA; enables precise base current sizing for predictable saturation control. |
| fT | 80MHz - Transition frequency at VCE = -10V, IE = -1mA; supports high-speed switching up to ~10MHz with adequate gain margin. |
| VCE(sat) | -150mV (typ.) - Collector-emitter saturation voltage at IC = -100mA, IB = -10mA; minimizes conduction loss in active-low switch configurations. |
| ESD HBM | 4,000V - Human Body Model rating per JESD22-A114; ensures robustness during board assembly and handling in non-ESD-controlled environments. |
Pinout & Package
Package: X2-DFN1006-3 - ultra-compact 0.60mm² footprint, 0.4mm max height, with exposed collector pad for thermal management and NiPdAu-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Current exit path in PNP operation; connected to most positive node in circuit (e.g., VCC or regulated rail). |
| 2 (Base) | Control input | Receives negative base current to turn on; requires current-limiting resistor referenced to emitter potential. |
| 3 (Collector) | Output/switch node | Connected to load and negative supply; exposed pad is electrically tied to collector and serves as primary thermal path. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 0.60mm² area - reduces PCB real estate by 13× vs. SOT-23, enabling dense power management and signal routing in wearables and IoT sensors. |
| Low-profile packaging | 0.4mm max height - minimizes off-board profile for slim enclosures and stacked PCB assemblies. |
| High thermal conductivity | RθJL = 120°C/W - allows efficient heat transfer from junction to solder point via exposed collector pad, supporting sustained 100mA operation. |
| Automotive-ready construction | Lead-free, halogen-free, antimony-free "Green" compound - meets RoHS 3 and supports AEC-Q101 qualification pathways for automotive-grade use. |
| Complementary pairing | Matched with DN0150BLP4 (NPN) - enables balanced push-pull, differential, or H-bridge designs with consistent gain, VBE, and fT characteristics. |
Applications
| LED Current Sink Driver | Low-Voltage Level Shifter |
|---|---|
Use Scenario: Driving RGB LEDs in portable displays where cathode-side current control is required with tight board space constraints. IC Role / Device Role / Timing Role: PNP switch configured in common-emitter mode, sinking current from LED anodes to ground through emitter-connected VCC. Use Value: Low VCE(sat) (-150mV) minimizes voltage drop across the transistor, preserving headroom for LED forward voltage and improving efficiency at 100mA drive levels. |
Use Scenario: Translating 3.3V logic signals to -5V or -12V domains in industrial I/O modules with isolated power rails. IC Role / Device Role / Timing Role: Active-low level shifter using emitter-follower or common-base topology to invert and shift voltage references between disparate supply domains. Use Value: -50V VCEO and -50V VCBO ensure reliable operation across wide negative swing ranges, while 80MHz fT supports clean edge transitions up to 10MHz clock rates. |
| DC-DC Converter Bias Network | Load Switch for Negative Rails |
Use Scenario: Providing bias current to error amplifiers or reference circuits in isolated flyback or buck-boost converters with negative output rails. IC Role / Device Role / Timing Role: Constant-current source or active pull-up element in feedback compensation networks requiring stable, temperature-invariant current sourcing. Use Value: Tight hFE spread (200–400) and low VBE(on) variation (-650mV to -950mV) enable accurate current mirroring and minimal drift over -55°C to +150°C ambient. |
Use Scenario: Enabling/disabling power to analog front-end circuits powered from -15V supplies in test equipment and medical instrumentation. IC Role / Device Role / Timing Role: High-side switch controlling connection between negative supply and load, with base driven by microcontroller GPIO through level-shifting resistor network. Use Value: 4kV HBM ESD rating protects against handling damage during manual assembly, and RθJL = 120°C/W permits 100mA continuous switching without external heatsink in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP small-signal transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DP0150BLP4-7 | Same die, active status, T6 marking; identical electrical specs and package. | Direct replacement with active production status and full manufacturer support. | Select when long-term supply continuity and AEC-Q101 qualification path are required. |
| MMDT3906-7 | SOT-23 package (3.05mm × 1.4mm), higher RθJA (400°C/W), lower fT (250MHz but measured at different conditions), same VCEO/IC ratings. | Larger footprint limits use in ultra-dense layouts; better suited for prototyping or legacy board upgrades. | Choose only if X2-DFN1006-3 rework capability is unavailable or thermal design accommodates higher junction rise. |
Compared with DP0150BLP4-7, the obsolete DP0150ALP4-7 shares identical silicon and performance but lacks ongoing manufacturing support; versus MMDT3906-7, it trades package size and thermal efficiency for broader assembly compatibility and higher-volume availability.

FAQ
Is DP0150ALP4-7 pin-compatible with DP0150BLP4-7?
Yes - both share identical X2-DFN1006-3 package, pinout (Emitter-Base-Collector), and mechanical dimensions. The only differences are part marking (T5 vs. T6) and product status (obsolete vs. active); electrical specifications are fully aligned per DS31493 Rev. 9-2.
What is the maximum continuous power dissipation for DP0150ALP4-7 in a typical PCB layout?
DP0150ALP4-7 is rated for 400mW continuous power dissipation when mounted on a standard 1oz copper PCB with minimum recommended pad layout and still-air conditions. This assumes full thermal coupling of the exposed collector pad to the copper pour; exceeding this requires derating based on ambient temperature and layout enhancements.
Can DP0150ALP4-7 be used in automotive applications?
While DP0150ALP4-7 itself is obsolete and not AEC-Q101 qualified, its active counterpart DP0150BLP4-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation. Diodes states that automotive-grade variants require specific change control - users must contact Diodes directly to obtain qualified versions.
How does the X2-DFN1006-3 package affect solder reflow and reliability?
The X2-DFN1006-3 uses NiPdAu-plated terminals and complies with MIL-STD-202 Method 208 for solderability. Its 0.4mm height and exposed collector pad demand precise stencil aperture design (0.15mm thickness, 0.35mm opening) and controlled reflow profiles to avoid voiding and tombstoning; JEDEC Level 1 moisture sensitivity eliminates bake requirements prior to assembly.
