Product details
Overview
PDTA144EM,315 from Nexperia is a PNP resistor-equipped transistor (RET) in a leadless ultra-small SOT883 (SC-101) package, featuring integrated 47 kΩ input and feedback bias resistors (R1 = R2 = 47 kΩ), −50 V collector-emitter breakdown voltage, −100 mA output current capability, and AEC-Q101 qualification for automotive digital switching applications.
For engineers reviewing the PDTA144EM,315 datasheet, PDTA144EM,315 pinout, PDTA144EM,315 application, or PDTA144EM,315 equivalent, this device serves as a space-optimized, pick-and-place–friendly alternative to discrete BJT + resistor networks in IC input control and low-power load switching circuits where board area and assembly cost are critical.
Technical Context
This PNP RET integrates matched 47 kΩ bias resistors (R1 and R2) with a precision 1.0 ±0.2 ratio, enabling reliable saturation at IC = −10 mA with IB = −0.5 mA and delivering VI(on) = −1.6 V (typ) and VI(off) = −1.2 V (typ) for robust logic-level interfacing.
Its SOT883 package provides 250 mW total power dissipation at Tamb ≤ 25 °C and a thermal resistance of 500 K/W (junction-to-ambient), supporting operation across −65 °C to +150 °C ambient and junction temperatures, with built-in ESD protection and AEC-Q101 stress qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Ensures safe operation in 24 V automotive and industrial supply rails with margin against transients. |
| IO | −100 mA - Supports direct driving of small relays, LEDs, or logic inputs without external amplification. |
| R1 | 47 kΩ (33–61 kΩ) - Sets base current for predictable turn-on; eliminates need for external bias resistor. |
| R2/R1 | 1.0 (0.8–1.2) - Enables stable active-region biasing and improves noise immunity in digital switching. |
| VCE(sat) | −150 mV (max) at IC = −10 mA / IB = −0.5 mA - Minimizes conduction loss and self-heating in high-duty-cycle switching. |
| fT | 180 MHz (typ) - Supports fast edge transitions in digital signal routing and interface buffering. |
| Ptot | 250 mW - Allows continuous operation at up to ~100 mA in compact PCB layouts with minimal copper area. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 2 kV). |
Pinout & Package
SOT883 (SC-101) is a leadless ultra-small plastic package measuring 1.0 × 0.6 × 0.5 mm, optimized for high-density PCBs and reflow-only assembly. Its three solder lands provide mechanical and electrical connection without leads, requiring precise stencil design and placement accuracy.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level control signals (e.g., MCU GPIO) to enable transistor conduction. |
| 2 | GND (emitter) | Common reference node; ties emitter directly to system ground-no external pull-down required. |
| 3 | Output (collector) | Switches loads connected between VCC and this terminal; supports sinking up to −100 mA with low saturation voltage. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched R1 = R2 = 47 kΩ resistors eliminate two external components and reduce BOM count by 66% vs discrete BJT + resistors. |
| Ultra-compact footprint | SOT883 body size (1.0 × 0.6 mm) saves >70% board area versus SOT23, enabling miniaturized modules and wearables. |
| Automotive qualification | AEC-Q101 certified for under-hood and infotainment applications, including extended temperature operation (−65 °C to +150 °C). |
| Low saturation voltage | VCE(sat) ≤ −150 mV ensures <15 mW conduction loss at 100 mA, reducing thermal stress in sealed enclosures. |
| Reflow-only assembly | Leadless construction mandates reflow soldering per JEDEC J-STD-020, eliminating wave soldering compatibility but improving coplanarity yield. |
Applications
| Automotive Body Control Module | Industrial PLC Input Isolation |
|---|---|
Use Scenario: Driving LED status indicators and small solenoid valves in door module ECUs. IC Role / Device Role / Timing Role: PNP switch sinking current from 12 V rail to ground under microcontroller GPIO control. Use Value: Eliminates discrete resistor network, reduces component count per channel, and meets AEC-Q101 vibration/thermal cycling requirements. |
Use Scenario: Level-shifting and isolating 24 V field sensor inputs to 3.3 V logic in modular I/O cards. IC Role / Device Role / Timing Role: Digital input buffer providing galvanic separation via optocoupler-compatible drive strength. Use Value: Delivers consistent −100 mA sink capability with <150 mV drop, enabling clean logic thresholds even with long cable runs. |
| Consumer IoT Sensor Hub | Medical Portable Device Power Sequencing |
Use Scenario: Enabling/disabling peripheral sensors (e.g., accelerometers, humidity ICs) to manage sleep-mode leakage. IC Role / Device Role / Timing Role: Low-leakage load switch controlled by ARM Cortex-M0+ wake-up pin. Use Value: VI(off) = −1.2 V ensures full cutoff at 0 V GPIO, minimizing standby current below 1 µA per channel. |
Use Scenario: Sequencing power delivery to analog front-end and RF subsystems during boot-up in handheld diagnostics tools. IC Role / Device Role / Timing Role: Precision-controlled PNP switch triggered by FPGA configuration state machine. Use Value: Tight R2/R1 ratio (0.8–1.2) guarantees repeatable turn-on timing across temperature, avoiding race conditions. |
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 |
|---|---|---|---|
| PDTC144EM | NPN complement with identical SOT883 package, R1/R2 values, and ratings; polarity reversal requires circuit redesign. | Used where active-high control or sourcing (vs sinking) is required-e.g., high-side LED anode drive. | Select when system architecture mandates NPN logic polarity or existing layout uses NPN RETs. |
| BC807-25,215 | Standard PNP BJT (no integrated resistors); requires two external bias resistors and occupies larger SOT23 footprint. | Suitable for analog biasing or variable-gain stages where resistor values must be tuned per application. | Choose only if adjustable hFE or non-standard R1/R2 ratios are needed; otherwise increases BOM and layout complexity. |
Compared with PDTC144EM, PDTA144EM,315 offers native PNP sinking functionality without polarity inversion, while versus BC807-25,215 it delivers 33% smaller footprint, guaranteed resistor matching, and AEC-Q101 qualification-making it optimal for high-volume, space-constrained automotive and industrial digital switching.

FAQ
What is the maximum operating temperature for PDTA144EM,315?
The PDTA144EM,315 has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its SOT883 package achieves 500 K/W thermal resistance, allowing sustained −100 mA operation at up to 85 °C ambient with standard FR4 PCB layout and no forced airflow.
Can PDTA144EM,315 replace BC857 in existing designs?
Yes-PDTA144EM,315 is positioned as a cost-saving, space-optimized alternative to BC857-series PNP transistors in digital switching. It integrates bias resistors, requires no external components, fits in 70% less area (SOT883 vs SOT23), and adds AEC-Q101 qualification-but pinout differs (SOT883 vs SOT23), so PCB layout revision is required.
Is reflow soldering mandatory for PDTA144EM,315?
Yes. Nexperia specifies reflow soldering as the only recommended method due to the SOT883 leadless construction. Wave soldering is not supported. The device requires JEDEC J-STD-020-compliant profile with peak temperature ≤ 260 °C, and its footprint uses three 0.3 × 0.6 mm solder lands aligned to 0.5 mm pitch.
What does the marking "DR" indicate on PDTA144EM,315?
"DR" is the official Nexperia marking code for PDTA144EM, as defined in Table 5 of the datasheet. It appears laser-etched on the top surface of the SOT883 package and serves as the primary identification for traceability, counterfeit prevention, and automated optical inspection (AOI) during assembly.
