Product details
Overview
PDTA144EQAZ from Nexperia is a 50 V, −100 mA PNP resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, integrating 47 kΩ input and feedback bias resistors. It functions as a digital switch for IC input control and load switching in space-constrained automotive and industrial PCBs, with AEC-Q101 qualification and −1.2 V to −0.8 V off-state input voltage.
For engineers reviewing the PDTA144EQAZ datasheet, PDTA144EQAZ pinout, PDTA144EQAZ application, or PDTA144EQAZ equivalent, key selection criteria include its built-in R1/R2 bias network (47 kΩ/47 kΩ), low 0.37 mm profile, −150 mV VCE(sat) at −10 mA/−0.5 mA, AEC-Q101 qualification, and compatibility with AOI solder-joint inspection.
Technical Context
This PNP RET integrates two precision-matched 47 kΩ bias resistors to enable direct logic-level drive without external components, reducing BOM count and layout area. Its internal transistor delivers hFE ≥ 80 at −5 mA collector current and −5 V VCE, supporting reliable saturation in digital switching applications.
The device operates across −55 °C to +150 °C ambient, with thermal resistance Rth(j-a) of 284 K/W on 4-layer FR4 PCBs. Its 3 pF collector capacitance and 180 MHz fT support stable high-speed switching up to tens of MHz while maintaining low power dissipation (440 mW max).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown in open-base configuration. |
| IO | −100 mA: Continuous output current capability for driving moderate loads like LEDs or small relays. |
| R1 / R2 | 47 kΩ / 47 kΩ: Integrated base bias network eliminates need for external resistors, simplifying PCB layout. |
| VCE(sat) | −150 mV at IC = −10 mA, IB = −0.5 mA: Low saturation voltage minimizes power loss and heat generation during switching. |
| hFE | ≥ 80 at VCE = −5 V, IC = −5 mA: Sufficient DC current gain ensures robust turn-on margin with standard logic drivers. |
| VI(off) | −1.2 V to −0.8 V at VCE = −5 V, IC = −100 µA: Well-defined off-threshold prevents unintended conduction with TTL or CMOS outputs. |
| Package | DFN1010D-3 (SOT1215): 1.1 × 1.0 × 0.37 mm ultra-thin leadless package enabling high-density routing and AOI-compatible assembly. |
Pinout & Package
DFN1010D-3 (SOT1215) is a 4-terminal leadless plastic package with visible side pads; body dimensions are 1.1 mm × 1.0 mm × 0.37 mm height. Pin 1 is marked by a beveled corner or dot; pins 3 and 4 are internally connected to the collector terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to logic signal source through integrated R1; sets transistor bias state. |
| 2 | GND (emitter) | Emitter tied to system ground; provides return path for load current. |
| 3 & 4 | Output (collector) | Dual collector terminals reduce trace inductance and improve current sharing in high-frequency switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and infotainment systems per stress test requirements. |
| Ultra-low profile (0.37 mm) | Enables use in ultra-thin portable and wearable electronics where Z-height is constrained. |
| Built-in matched bias resistors | Eliminates two external 47 kΩ resistors, reducing placement cost and board area by ~1.2 mm². |
| AOI-solder-joint compatible | Exposed side pads allow automated optical inspection of solder fillets, improving manufacturing yield. |
| Reduced component count | Replaces discrete PNP + two resistors, lowering BOM management overhead and supply chain complexity. |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door modules and lighting controllers. IC Role / Device Role / Timing Role: PNP RET acts as level-shifted, current-amplified driver between MCU GPIO and higher-current loads. Use Value: AEC-Q101 rating ensures reliability over temperature cycling; low VCE(sat) limits self-heating in sealed enclosures. |
Use Scenario: Isolating and buffering digital inputs from field sensors (e.g., limit switches, proximity detectors) in DIN-rail mounted controllers. IC Role / Device Role / Timing Role: Digital interface buffer that translates 24 V industrial logic to 3.3 V/5 V MCU inputs with noise immunity. Use Value: Built-in bias network rejects EMI-induced false triggering; wide −55 °C to +150 °C operation supports uncooled cabinet deployment. |
| Consumer Smart Home Hub | Medical Diagnostic Equipment |
Use Scenario: Controlling RGB LED status indicators and relay-based power sequencing in voice-controlled hubs. IC Role / Device Role / Timing Role: Compact load switch enabling rapid on/off transitions with minimal footprint. Use Value: DFN1010D-3 package allows dense LED driver arrays; 180 MHz fT supports clean edge integrity in PWM dimming up to 20 kHz. |
Use Scenario: Enabling/disabling sensor bias rails and analog front-end power domains in portable ultrasound or ECG units. IC Role / Device Role / Timing Role: Precision-controlled power gate ensuring zero leakage during standby and fast wake-up response. Use Value: VI(off) ≤ −1.2 V guarantees full cutoff with 3.3 V logic; low 90 µA IEBO at 25 °C preserves battery life in sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC144EQA | NPN complement with identical 47 kΩ bias network and DFN1010D-3 package; VCEO = +50 V, IO = +100 mA. | Used where active-low logic drive or NPN sinking topology is required instead of PNP sourcing. | Select when interfacing with open-collector/drain outputs or when load must be switched to ground. |
| BC857B,215 | Discrete PNP BJT (no integrated resistors); SOT23 package; hFE = 200–450; requires external base resistor network. | Suitable for analog amplification or precision biasing where variable gain or adjustable threshold is needed. | Choose only if design requires tunable hFE or non-standard bias ratios; adds two passives and layout area. |
Compared with PDTC144EQA, PDTA144EQAZ provides sourcing capability and negative logic compatibility; versus BC857B,215, it eliminates resistor placement and improves production yield but sacrifices gain adjustability.

FAQ
What is the maximum operating temperature for PDTA144EQAZ?
The PDTA144EQAZ has a specified junction temperature limit of 150 °C and an ambient operating range of −55 °C to +150 °C. On a 4-layer FR4 PCB, its thermal resistance is 284 K/W, allowing 440 mW total power dissipation at 25 °C ambient - derating linearly above that point per the published curve.
Can PDTA144EQAZ replace BC857 in existing designs?
Yes, as a drop-in functional alternative in digital switching roles, provided the circuit uses PNP sourcing and logic levels align with PDTA144EQAZ's VI(on) (−3 V to −1.6 V) and VI(off) (−1.2 V to −0.8 V). No external resistors are needed, but layout must accommodate the smaller DFN1010D-3 footprint instead of SOT23.
Is the collector terminal electrically split between pins 3 and 4?
No - pins 3 and 4 are internally shorted to the same collector node. This dual-terminal design lowers parasitic inductance and improves current handling uniformity; both pads must be soldered to the same copper pour or net in layout.
Does PDTA144EQAZ support PWM dimming of LEDs?
Yes - with a transition frequency (fT) of 180 MHz and 3 pF collector capacitance, PDTA144EQAZ supports clean switching at PWM frequencies up to at least 20 kHz. Its −150 mV VCE(sat) minimizes conduction loss, and the 0.37 mm profile aids thermal management in LED driver arrays.
