Product details
Overview
PDTA124EU,115 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) surface-mount package, designed for digital switching applications with built-in bias resistors R1 = 22 kΩ and R2 = 22 kΩ, −100 mA output current capability, −50 V collector-emitter voltage rating, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA124EU,115 datasheet, PDTA124EU,115 pinout, PDTA124EU,115 application, or PDTA124EU,115 equivalent, key selection considerations include its integrated base resistors, compact SC-70 footprint, guaranteed VI(on)/VI(off) thresholds, thermal resistance of 625 K/W, and suitability as a drop-in replacement for BC857-series transistors in logic-level interface circuits.
Technical Context
This PNP RET integrates two precision thin-film resistors (R1 = 22 kΩ, R2 = 22 kΩ) directly into the die assembly, eliminating external bias components and reducing PCB area. Its internal transistor exhibits hFE ≥ 60 at IC = −5 mA and VCE = −5 V, with VI(on) = −1.7 V (typ) enabling reliable turn-on from standard 3.3 V or 5 V logic outputs.
The device operates across −65 °C to +150 °C ambient, supports reflow-only soldering per JEDEC J-STD-020, and delivers −150 mV VCE(sat) at IC = −10 mA/IB = −0.5 mA - confirming low-loss switching performance in high-density digital control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage under open-base conditions, enabling use in 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous output current rating, sufficient for driving LED indicators, small relays, or logic inputs without external heat sinking. |
| R1 | 22 kΩ ±30%: Integrated input bias resistor, eliminates need for discrete base resistor and reduces BOM count by one component. |
| R2/R1 | 1.0 ±20%: Matched feedback-to-input resistor ratio, ensures stable saturation and predictable turn-off behavior across temperature. |
| VI(on) | −1.7 V (typ): On-state input voltage threshold, guarantees activation from 3.3 V CMOS outputs with ≥1.6 V noise margin. |
| VCE(sat) | −150 mV (max): Low saturation voltage at rated current, minimizing power loss (≤15 mW) in active-switching mode. |
| Ptot | 200 mW @ Tamb ≤ 25 °C: Total power dissipation limit on FR4 PCB, defining thermal derating curve for sustained operation. |
| Rth(j-a) | 625 K/W: Junction-to-ambient thermal resistance, used to calculate maximum junction temperature rise under load. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package with 3 leads; body dimensions 2.2 mm × 1.35 mm × 1.15 mm; standard footprint compatible with automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive signal; requires no external pull-up or pull-down. |
| 2 | GND (emitter) | Common emitter reference node; serves as return path for both input and output currents. |
| 3 | Output (collector) | Switched high-side output node; sinks current when active; connects to load between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates two external resistors, reducing layout area and assembly steps in digital interface circuits. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
| Low VCE(sat) | −150 mV max ensures <15 mW conduction loss at 100 mA, critical for thermally constrained modules. |
| SC-70 package | 2.2 × 1.35 mm footprint enables high-density routing in space-constrained consumer and industrial PCBs. |
| VI(off) ≤ −0.8 V | Guaranteed off-state threshold prevents false triggering from noise or floating inputs in noisy environments. |
Applications
| Automotive LED Control | Industrial I/O Expansion |
|---|---|
Use Scenario: Driving status indicator LEDs on dashboard control units and body electronics modules. IC Role / Device Role / Timing Role: High-side switch controlling current flow from 12 V rail to LED anode; operates in DC on/off mode. Use Value: Built-in resistors eliminate need for discrete base biasing, reducing BOM cost and board area while maintaining AEC-Q101 compliance. | Use Scenario: Level-shifting and buffering GPIO signals between microcontrollers and 24 V PLC field inputs. IC Role / Device Role / Timing Role: Digital input conditioner converting 24 V field signals to 3.3 V logic-compatible levels via open-collector interface. Use Value: −50 V VCEO rating provides robustness against inductive kickback; SC-70 size allows dense placement near connector headers. |
| Consumer Power Sequencing | Medical Sensor Interface |
Use Scenario: Enabling/disabling auxiliary power rails (e.g., display backlight, sensor bias) in portable diagnostic devices. IC Role / Device Role / Timing Role: Load switch controlled by MCU GPIO; operates in static on/off states with minimal quiescent current. Use Value: −100 mA rating supports typical backlight loads; VI(on) = −1.7 V ensures compatibility with 3.3 V MCU outputs without level shifters. | Use Scenario: Isolating analog sensor outputs from digital processing stages in wearable health monitors. IC Role / Device Role / Timing Role: Signal gating element preventing cross-talk during ADC sampling windows; activated synchronously with conversion timing. Use Value: Low VCE(sat) minimizes voltage drop in signal path; SC-70 package enables co-location with miniature sensors on flex PCBs. |
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 |
|---|---|---|---|
| PDTC124EU,115 | NPN complement with identical R1/R2 values, package, and thermal specs; VI(on) polarity reversed (+1.7 V typ). | Used where logic-active-high drive is preferred or where NPN topology simplifies existing schematic layout. | Select when interfacing with active-high controllers or when matching NPN-based reference designs. |
| BC857BW,115 | Discrete PNP transistor without integrated resistors; requires external RB; higher hFE (125–630) but no VI(on)/VI(off) guarantees. | Suitable for analog amplification or variable-bias applications where gain linearity matters more than digital switching predictability. | Choose only if precise bias tuning is required; otherwise PDTA124EU offers lower design risk and faster time-to-market. |
Compared with PDTC124EU,115, PDTA124EU provides complementary logic polarity and identical form factor; versus BC857BW,115, it trades external bias flexibility for guaranteed switching thresholds, reduced component count, and simplified layout verification.

FAQ
What is the maximum operating temperature for PDTA124EU,115?
The PDTA124EU,115 has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 625 K/W on FR4 PCB, so at 100 mA and VCE(sat) = −150 mV, power dissipation is 15 mW - resulting in ~9.4 °C junction rise above ambient, well within limits.
Can PDTA124EU,115 be used as a direct replacement for BC857B in existing designs?
Yes, but only in digital switching roles where base biasing is standardized. PDTA124EU integrates 22 kΩ resistors and guarantees VI(on)/VI(off), whereas BC857B requires external bias. Layout must accommodate SOT323 vs. SOT23 footprint differences, and polarity remains PNP in both cases.
Does PDTA124EU,115 support wave soldering?
No - the datasheet explicitly states "reflow soldering is the only recommended soldering method." Wave soldering is not qualified for this device due to thermal stress risks on the ultra-thin leadframe and internal resistor elements; use only JEDEC-compliant reflow profiles.
What does the marking code *05 indicate on PDTA124EU,115 units?
The marking code *05 on PDTA124EU,115 indicates the device variant and manufacturing site; the asterisk (*) is a placeholder for the actual production location code (e.g., 'A' for Nijmegen, 'B' for Bangkok), while '05' identifies the PDTA124E series within Nexperia's SOT323 RET family.
