Product details
Overview
PDTA115EU,115 from NXP Semiconductors is a PNP resistor-equipped transistor (RET) with integrated 100 kΩ base-emitter and base-collector bias resistors, designed for simplified switching in low-power digital interface circuits. It delivers −20 mA DC output current, −50 V collector-emitter breakdown voltage, and −150 mV saturation voltage at −5 mA collector current, enabling direct microcontroller GPIO drive in level-shifting and signal inversion applications.
For engineers reviewing the PDTA115EU,115 datasheet, PDTA115EU,115 pinout, PDTA115EU,115 application, or PDTA115EU,115 equivalent, this part serves as a drop-in replacement for discrete PNP + two-resistor configurations in space-constrained SOT323 layouts where thermal resistance (625 K/W) and input-off voltage (−1.2 to −0.5 V) are critical for noise-immune logic-level translation.
Technical Context
This RET integrates two precision 100 kΩ bias resistors (R1 = R2 = 100 kΩ, tolerance ±30%) directly into a monolithic PNP silicon die, eliminating external components while preserving predictable turn-on/off thresholds. Its fixed resistor ratio (1.0 ±20%) ensures stable current gain (hFE = 80 min at −5 mA) across temperature without trimming.
The device operates with a maximum junction temperature of 150 °C and requires reflow soldering only-no wave or hand-soldering-due to its SOT323 package construction and thermal limits. Input voltage range spans −40 V to +10 V, supporting robust interfacing with mixed-voltage systems including 3.3 V and 5 V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 36 V automotive or industrial bus interfaces. |
| IO (DC) | −20 mA: Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs without external amplification. |
| R1 / R2 | 100 kΩ each: Integrated bias resistors reduce BOM count by two components and eliminate layout sensitivity to parasitic capacitance. |
| VCE(sat) | −150 mV @ −5 mA: Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching applications. |
| Ptot | 200 mW @ Tamb ≤ 25 °C: Power dissipation limit defines maximum continuous load under standard PCB mounting conditions. |
| Rth(j-a) | 625 K/W: Junction-to-ambient thermal resistance confirms need for minimal copper pour or derating above 70 °C ambient. |
| hFE | 80 min @ VCE = −5 V, IC = −5 mA: Guaranteed DC current gain ensures reliable switching margin with typical microcontroller output drive strength. |
Pinout & Package
Package: SOT323 (SC-70), plastic surface-mounted package; 3 leads, body size 2.2 × 1.35 × 0.95 mm. Standard reflow-only assembly per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Internal connection to both bias resistors (R1 and R2) | Single-point bias node simplifies PCB routing and eliminates external resistor node vulnerability to ESD or crosstalk. |
| 2 (Emitter) | Emitter terminal of PNP transistor | Connected to system ground or low-side reference; polarity defines active-low switching behavior in common-emitter configuration. |
| 3 (Collector) | Collector terminal of PNP transistor | Output node tied to load supply rail; sinks current when base is pulled low relative to emitter. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors (R1 = R2 = 100 kΩ) | Eliminates two external 0402/0603 resistors, reducing placement time and board area by ≥2.5 mm² in SOT323 layout. |
| Input-off voltage (Vi(off)) | −1.2 to −0.5 V: Ensures reliable cutoff with TTL/CMOS logic high outputs, preventing unintended conduction during idle states. |
| Collector capacitance (Cc) | 3 pF @ VCB = −10 V: Low parasitic capacitance supports >100 MHz switching in RF-coupled or fast edge-detection circuits. |
| Thermal resistance (Rth(j-a)) | 625 K/W: Quantifies thermal bottleneck in standard FR4; guides copper pad sizing and airflow requirements for sustained −20 mA operation. |
| Storage temperature range | −65 to +150 °C: Supports extended industrial and automotive storage logistics without parametric shift or packaging degradation. |
Applications
| Logic Level Translation | Microcontroller GPIO Driver |
|---|---|

Use Scenario: Isolating sensitive analog or communication ICs from noisy digital control lines. IC Role / Device Role / Timing Role: Buffer stage absorbing transient currents and clamping voltage excursions. Use Value: Withstands −40 V input transients via integrated resistor current limiting, reducing need for external TVS diodes. |
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 |
|---|---|---|---|
| PDTC115EU | NPN complement with identical R1/R2 values and SOT323 package; VCEO = +50 V, IO = +20 mA | Requires inverted logic control (active-high instead of active-low); suited for high-side sourcing rather than low-side sinking | Select when driving loads referenced to VCC instead of GND, or when matching existing NPN-based board designs. |
| EMH11T2R | PNP RET with R1 = 10 kΩ, R2 = 10 kΩ; same SOT323 footprint but lower bias resistance and higher IO = −100 mA | Higher base current draw reduces noise immunity; optimized for higher-speed switching (>10 MHz) at cost of static power | Choose for faster edge rates or heavier loads where 100 mA sink capability is required and input drive strength permits. |
Compared with PDTC115EU and EMH11T2R, PDTA115EU,115 provides optimal balance of noise margin (via 100 kΩ bias), thermal efficiency (200 mW rating), and compatibility with standard 3.3 V/5 V logic thresholds-making it preferred for general-purpose, low-power interface tasks where reliability and simplicity outweigh speed or current demands.

FAQ
Is PDTA115EU,115 compatible with lead-free reflow processes?
Yes. The device is qualified for lead-free reflow soldering per JEDEC J-STD-020, with peak temperature up to 260 °C. Wave soldering and hand soldering are not recommended due to thermal stress risks on the SOT323 package and internal resistor elements.
What is the maximum operating frequency for switching applications?
While not characterized as a high-frequency RF device, PDTA115EU,115 supports digital switching up to approximately 10 MHz based on its 3 pF collector capacitance and typical turn-on/turn-off times derived from hFE and R1/R2 values. For >10 MHz use, consult NXP's application note AN10782 for layout and drive optimization.
Can PDTA115EU,115 be used in linear amplifier mode?
No. This part is optimized for saturated switching operation only. Its integrated bias network and specified parameters (e.g., VCE(sat), hFE min) reflect digital interface use-not analog amplification. Linear operation would cause unpredictable gain and thermal instability due to uncontrolled base current paths.
How does the resistor ratio affect switching performance?
The R1/R2 ratio of 1.0 ±20% ensures symmetrical biasing that stabilizes the turn-on threshold against process variation. Deviations beyond this range increase dispersion in Vi(on) and Vi(off), potentially causing marginal switching in low-noise or high-temperature environments where precise logic thresholds are required.
