Product details
Overview
PDTA144EU,115 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching applications with built-in bias resistors R1 = 47 kΩ and R2 = 47 kΩ, −50 V VCEO rating, −100 mA output current capability, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA144EU,115 datasheet, PDTA144EU,115 pinout, PDTA144EU,115 application, or PDTA144EU,115 equivalent, key selection criteria include integrated resistor ratio (R2/R1 = 1), VI(on)/VI(off) thresholds (−1.6 V / −1.2 V typ), thermal resistance (625 K/W), and compatibility with reflow-only assembly on FR4 PCBs.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 47 kΩ, R2 = 47 kΩ) to eliminate external base components, enabling direct logic-level drive from microcontrollers or gate drivers. Its −100 mA continuous output current supports load switching up to 100 mA at VCE ≤ −0.15 V saturation.
The device operates across −65 °C to +150 °C ambient, features 80 minimum DC current gain (hFE) at IC = −5 mA, and delivers stable VI(on) and VI(off) performance across temperature (−40 °C to +100 °C), making it suitable for harsh-environment digital interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage with open base; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LEDs, relays, or logic inputs without external current limiting. |
| R1 | 47 kΩ (typ) - Input bias resistor value; sets base current for predictable turn-on with standard CMOS/TTL logic levels. |
| R2/R1 | 1.0 (typ) - Matched internal resistor ratio; ensures stable bias network behavior and reduces sensitivity to process variation. |
| VCEsat | −150 mV (max) at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| VI(on) | −1.6 V (typ) at VCE = −0.3 V, IC = −2 mA - Confirmed turn-on threshold compatible with 3.3 V and 5 V logic families. |
| VI(off) | −1.2 V (typ) at VCE = −5 V, IC = −100 μA - Verified off-state input voltage ensuring reliable cutoff under noise or leakage conditions. |
Pinout & Package
SOT323 (SC-70) surface-mount plastic package: 3-lead, body size 2.2 mm × 1.35 mm × 1.15 mm, optimized for high-density PCB layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1 and R2; accepts logic-level control signal directly without external pull-up/down. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for both bias network and output path. |
| 3 | Output (collector) | Switched output node; sinks current to ground when active, enabling high-side load control via emitter-follower configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates two external resistors, reducing BOM count and PCB area while improving assembly yield. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
| Reflow-only assembly | Designed exclusively for lead-free reflow processes; wave soldering not recommended due to thermal profile constraints. |
| Low thermal resistance | Rth(j-a) = 625 K/W on FR4 PCB - enables operation up to 100 mA without heatsinking in typical industrial ambient conditions. |
| Digital interface optimization | VI(on)/VI(off) thresholds tightly specified to ensure robust switching with 3.3 V/5 V logic, minimizing false triggering. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|
Use Scenario: Level-shifting and isolation of 12 V/24 V sensor signals into 3.3 V microcontroller GPIOs. IC Role / Device Role / Timing Role: PNP RET acts as an active-low level translator and current-limiting interface, replacing discrete transistor + resistor combinations. Use Value: Reduces component count by 2 per channel and improves ESD robustness over bare transistors due to integrated resistor protection. |

IC Role / Device Role / Timing Role: Provides galvanically isolated, debounced digital input conditioning with built-in hysteresis via resistor network. Use Value: Enables direct connection to 24 V industrial field wiring without external pull-up or clamping diodes, lowering system cost and footprint. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Status Indication |
Use Scenario: Controlled enable/disable sequencing of auxiliary power rails during startup/shutdown in smart home hubs. IC Role / Device Role / Timing Role: Functions as a low-power, fast-turnoff switch for 5 V standby rail control, driven by MCU GPIO. Use Value: Achieves <1 μs turn-off delay and <100 ns propagation skew across channels, supporting precise timing-critical sequencing. |
Use Scenario: Driving LED status indicators in battery-powered portable diagnostic devices requiring ultra-low quiescent current. IC Role / Device Role / Timing Role: Serves as a low-leakage, high-impedance output driver with ICEO < −1 μA at 150 °C junction temperature. Use Value: Extends battery life by minimizing standby current draw while maintaining full brightness during active indication. |
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 |
|---|---|---|---|
| PDTC144EU,115 | NPN complement with identical R1/R2 values, package, and thermal specs; VI(on)/VI(off) polarities reversed. | Requires inverted logic drive; used where active-high control or NPN sink topology is preferred. | Select when interfacing with open-collector outputs or needing complementary switching in push-pull configurations. |
| BC857BW,115 | Discrete PNP BJT without integrated resistors; requires external R1/R2; higher hFE (125–475) but no built-in bias network. | Demands additional passives and layout space; offers greater flexibility in bias point tuning but increases BOM and assembly steps. | Choose when precise, adjustable base current or multi-stage amplification is required beyond simple switching. |
Compared with PDTC144EU,115, PDTA144EU,115 provides native active-low switching with guaranteed VI thresholds, while BC857BW,115 trades integration for design flexibility-making PDTA144EU optimal for high-volume, space-constrained digital interface applications.

FAQ
Is PDTA144EU,115 compatible with lead-free reflow soldering?
Yes, PDTA144EU,115 is qualified exclusively for lead-free reflow soldering per J-STD-020; its SOT323 package and internal construction meet peak temperature requirements up to 260 °C. Wave soldering is not recommended and may cause reliability degradation due to thermal stress on the die attach and bond wires.
What is the maximum ambient temperature for continuous −100 mA operation?
At Tamb = 25 °C, PDTA144EU,115 supports −100 mA continuously with Ptot ≤ 200 mW. Derating begins above 25 °C; at Tamb = 85 °C, maximum sustainable current drops to approximately −65 mA based on Rth(j-a) = 625 K/W and Tj(max) = 150 °C. Full derating curve is provided in Figure 5 of the datasheet.
Can PDTA144EU,115 replace BC847/857 series transistors directly?
It can serve as a drop-in functional replacement in digital switching roles where built-in bias resistors are acceptable, offering reduced component count and simplified layout. However, it is not electrically identical: BC847/857 require external biasing, offer wider hFE range, and lack integrated resistors-so analog amplification or adjustable bias applications require redesign.
Does PDTA144EU,115 support bidirectional signal translation?
No, PDTA144EU,115 is a unidirectional PNP switch optimized for active-low digital control. It lacks symmetrical characteristics or internal circuitry for bidirectional level shifting; its VI(on)/VI(off) thresholds and saturation behavior are defined only for forward (input-to-output) conduction, and reverse current flow is not characterized or supported.
