Product details
Overview
PDTA115EU-Q from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, featuring integrated bias resistors R1 = 100 kΩ and R2 = 100 kΩ, VCEO = −50 V, IO = −20 mA, and AEC-Q101 qualification for automotive interface and switching applications.
For engineers reviewing the PDTA115EU-Q datasheet, PDTA115EU-Q pinout, PDTA115EU-Q application, or PDTA115EU-Q equivalent, key selection criteria include its built-in 1:1 R2/R1 ratio, −150 mV VCEsat at −5 mA/−0.25 mA, and thermal resistance of 625 K/W on FR4 PCB - critical for space-constrained automotive signal conditioning designs.
Technical Context
This RET integrates two precision-matched 100 kΩ bias resistors to configure the base drive network, eliminating external components while maintaining predictable turn-on/off thresholds across temperature. Its PNP topology enables high-side switching with simplified level-shifting in 3.3 V/5 V logic-driven circuits.
The device operates within −65 °C to +150 °C ambient range, supports peak collector current up to −100 mA, and delivers DC current gain (hFE) ≥ 80 at −5 mA collector current and −5 V VCE, ensuring reliable saturation in low-power driver stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum safe collector-emitter voltage with open base; defines off-state blocking capability in automotive load switching. |
| IO | −20 mA - continuous output (collector) current rating; sets upper limit for steady-state switching or amplification loads. |
| R1 / R2 | 100 kΩ / 100 kΩ - matched input bias resistors enabling single-resistor-equivalent base drive without external components. |
| VCEsat | −150 mV at IC = −5 mA, IB = −0.25 mA - low saturation voltage minimizes power loss and heating in active switching mode. |
| hFE | ≥ 80 at VCE = −5 V, IC = −5 mA - ensures sufficient current amplification for robust digital interface translation. |
| Ptot | 200 mW at Tamb ≤ 25 °C - total power dissipation limit on standard FR4 PCB; derates linearly above 25 °C per Fig. 1. |
| Rth(j-a) | 625 K/W - junction-to-ambient thermal resistance on single-sided FR4; determines temperature rise under load. |
Pinout & Package
Package: SOT323 (SC-70), plastic surface-mounted, 3-lead, 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level control signal and provides current-limited base drive via integrated resistor network. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths in PNP configuration. |
| 3 | Output (collector) | Switched output node; sinks current when active; connects to load between supply rail and this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | R1 = R2 = 100 kΩ ±30 % with 0.8–1.2 R2/R1 ratio - eliminates external base resistors and reduces layout sensitivity to trace parasitics. |
| AEC-Q101 qualification | Qualified for automotive applications per Stress Test Qualification for Discrete Semiconductors - supports deployment in engine control, body electronics, and ADAS subsystems. |
| Low VCEsat | −150 mV at rated IC/IB - reduces conduction loss and self-heating in battery-powered or thermally constrained modules. |
| Small-footprint packaging | SOT323 (SC-70) - occupies 2.5 mm² board area, enabling high-density placement in compact ECUs and sensor nodes. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Input Interface |

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 |
|---|---|---|---|
| PDTA114EU-Q | R1 = 100 kΩ, R2 = 47 kΩ (R2/R1 ≈ 0.47); lower base current gain ratio | Better suited for higher-speed switching where reduced base charge storage improves turn-off time | Select when faster response is prioritized over input threshold symmetry |
| PDTC114EU-Q | NPN polarity, same R1/R2 values and package; complementary topology | Required for low-side switching configurations or push-pull driver pairs | Choose for NPN-based architectures or dual RET implementations needing matched bias networks |
Compared with PDTA115EU-Q, PDTA114EU-Q offers asymmetric biasing for optimized switching speed, while PDTC114EU-Q provides NPN complementarity - both retain AEC-Q101 qualification and SC-70 footprint but differ in polarity and resistor ratio, directly affecting drive strength and circuit topology compatibility.

FAQ
What is the maximum allowable input voltage at Pin 1 (I) for PDTA115EU-Q?
The absolute maximum input voltage at Pin 1 is −40 V to +10 V, as specified in Table 5 (Limiting Values). Exceeding −40 V risks breakdown of the internal R1 resistor or base-emitter junction; operation above +10 V may cause irreversible damage to the integrated bias network.
Can PDTA115EU-Q be used in high-frequency switching applications above 1 MHz?
No - its collector capacitance is 3 pF at −10 V VCB, and no switching time data (ton/toff) is provided in the datasheet. The device is characterized for DC and low-frequency (<100 kHz) switching; use requires validation of dynamic performance in target circuit conditions.
Is the R2/R1 ratio guaranteed across temperature and process variation?
Yes - the R2/R1 ratio is specified as 0.8 to 1.2 over Tamb = 25 °C (Table 4), and the device's AEC-Q101 qualification includes bias resistor matching stability testing across temperature cycling and lifetime stress, ensuring functional consistency in automotive environments.
Does PDTA115EU-Q require an external emitter resistor for current limiting?
No - the integrated R1 and R2 form a complete base bias network; no external emitter resistor is needed for basic switching operation. However, if precise current regulation or fault protection beyond −20 mA is required, an external emitter resistor may be added in series with Pin 2 (GND) to enforce additional current limiting.
