Product details
Overview
PDTA115TMB from Nexperia is a PNP resistor-equipped transistor (RET) in a leadless DFN1006B-3 (SOT883B) package, designed for digital switching and IC input control with built-in 100 kΩ base bias resistor, −50 V VCEO, −100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA115TMB datasheet, PDTA115TMB pinout, PDTA115TMB application, or PDTA115TMB equivalent, this device serves as a space-optimized, drop-in replacement for discrete PNP + bias resistor networks in low-current peripheral driver circuits, mobile interface logic, and automotive body electronics where board area and assembly cost are critical.
Technical Context
This PNP RET integrates a single bipolar transistor with an on-die 100 kΩ input bias resistor (R1) and open R2 configuration, eliminating external base resistors. It operates with VCE = −5 V at IC = −1 mA for hFE ≥ 100 and delivers VCE(sat) ≤ −150 mV at IC = −5 mA / IB = −0.25 mA.
Thermal performance is defined by Rth(j-a) = 500 K/W on FR4 PCB, with Tj rated to 150 °C and ambient operating range from −65 °C to +150 °C. Its 0.37 mm profile supports ultra-thin portable and automotive modules requiring minimal Z-height.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Supports reliable switching in 24 V automotive and industrial logic interfaces without breakdown risk. |
| IO | −100 mA - Sufficient drive capability for LED indicators, small relays, and microcontroller GPIO load switching. |
| R1 | 100 kΩ (70–130 kΩ typ) - Enables direct connection to 3.3 V/5 V logic outputs without external bias components. |
| VCE(sat) | ≤ −150 mV at IC = −5 mA - Minimizes power loss and self-heating in always-on or pulsed control applications. |
| hFE | ≥ 100 at VCE = −5 V, IC = −1 mA - Ensures robust turn-on margin across temperature and process variation. |
| fT | 180 MHz - Supports fast digital switching up to ~10 MHz with stable gain and minimal propagation delay. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Matches thermal limits of ultra-small DFN1006B-3 footprint on standard FR4 PCBs. |
Pinout & Package
DFN1006B-3 (SOT883B) is a 3-terminal, leadless, ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.37 mm with exposed pad not connected internally. Its low-profile construction enables high-density routing and compatibility with automated reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected to internal 100 kΩ bias resistor; accepts logic-level voltage directly from MCU or gate output. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides reference for PNP switching action and current return path. |
| 3 | Output (collector) | Switched high-side output node; sinks current when active, suitable for driving loads referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 100 kΩ base resistor | Eliminates two external passive components per switch, reducing BOM count and PCB real estate by >30% vs discrete solutions. |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin applications including lighting control, sensor interface, and body ECU modules. |
| 0.37 mm package height | Enables use in ultra-thin consumer wearables and stacked PCB assemblies where Z-axis clearance is constrained. |
| −100 mA continuous output | Supports direct drive of status LEDs, small solenoids, and logic-level MOSFET gates without additional buffering. |
| Low VCE(sat) (≤ −150 mV) | Reduces conduction loss to <0.75 mW at 5 mA, improving efficiency and thermal stability in battery-powered systems. |
Applications
| Automotive Interior Lighting Control | Mobile Device Status Indication |
|---|---|
Use Scenario: Driving white or RGB indicator LEDs in door modules, HVAC panels, and center consoles. IC Role / Device Role / Timing Role: High-side PNP switch controlling LED anode connection to 5 V/12 V rail with logic-level enable from MCU GPIO.

IC Role / Device Role / Timing Role: Low-power digital switch turning on/off LED current paths based on processor interrupt signals. Use Value: 0.37 mm height fits thin form factors; 100 mA rating covers multi-LED strings; low VCE(sat) extends battery runtime. |
| Industrial Sensor Interface Logic | IoT Edge Node Power Sequencing |
Use Scenario: Level-shifting and enabling analog sensor bias rails or digital enable lines in PLC I/O modules. IC Role / Device Role / Timing Role: Signal conditioning switch isolating MCU I/O from higher-voltage sensor subsystems. Use Value: −50 V VCEO withstands transient surges in factory environments; Rth(j-a) = 500 K/W supports operation up to 105 °C ambient. |
Use Scenario: Controlled power-up sequencing of RF transceivers, memory, and sensors in battery-operated edge nodes. IC Role / Device Role / Timing Role: Precision timing-controlled switch enabling subsystem power domains via MCU GPIO. Use Value: Fast fT = 180 MHz ensures clean edge transitions; tight R1 tolerance (±30%) guarantees consistent turn-on timing across units. |
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 |
|---|---|---|---|
| PDTC115TMB | NPN complement with identical R1 = 100 kΩ, same DFN1006B-3 package, but opposite polarity and sourcing (not sinking) behavior. | Used where low-side switching or inverted logic control is required instead of high-side PNP sink configuration. | Select PDTC115TMB only when circuit topology demands NPN logic or emitter-follower output stage. |
| PDTA123TMB | Same PNP RET architecture but with R1 = 2.2 kΩ, delivering higher base drive for faster switching and higher IC capability (up to −200 mA). | Suitable for higher-current loads like buzzer drivers or dual-LED arrays where PDTA115TMB's 100 mA limit is insufficient. | Choose PDTA123TMB when VCE(sat) must be minimized below −100 mV or when hFE margin is needed above 200 at IC = −10 mA. |
Compared with PDTC115TMB and PDTA123TMB, PDTA115TMB offers optimal balance of low quiescent current, compact size, and automotive-grade reliability for medium-speed, low-power digital switching-making it preferred for space-constrained, logic-level interfacing tasks where 100 mA suffices.

FAQ
Is PDTA115TMB pin-compatible with other DFN1006B-3 RETs?
Yes - all Nexperia DFN1006B-3 RETs (e.g., PDTA123TMB, PDTC114TMB) share identical mechanical footprint, solder land pattern, and pin 1–2–3 assignment. However, electrical characteristics (R1 value, polarity, VCEO) differ, so functional substitution requires circuit validation.
What is the maximum recommended PCB copper area for thermal relief?
Nexperia specifies thermal resistance data for a single-sided FR4 PCB with standard footprint and tin-plated copper. For improved dissipation, extend copper pour under the exposed pad (though unconnected), and add thermal vias to inner layers if multilayer boards are used - no minimum copper area is mandated beyond the footprint itself.
Does PDTA115TMB support 1.8 V logic input levels?
No - with R1 = 100 kΩ, the base current at 1.8 V is only ~18 µA, insufficient to reliably saturate the transistor at rated IO. Minimum recommended logic high is 3.0 V (IB ≈ 30 µA), aligning with standard 3.3 V CMOS output specifications.
Can PDTA115TMB be used in linear amplifier mode?
No - this device is optimized and characterized for digital switching only. Its hFE is specified at a single DC operating point (IC = −1 mA), and no linearity, distortion, or small-signal parameters (e.g., gm, rπ) are guaranteed or tested per datasheet.
