Product details
Overview
PDTA114TMB from Nexperia is a PNP resistor-equipped transistor (RET) in a leadless DFN1006B-3 (SOT883B) package, designed for digital switching and low-current peripheral driving. It features integrated 10 kΩ input bias resistor (R1), −50 V collector-emitter voltage rating, −100 mA output current capability, AEC-Q101 qualification, and 0.37 mm package height-enabling compact automotive and mobile interface control.
For engineers reviewing the PDTA114TMB datasheet, PDTA114TMB pinout, PDTA114TMB application, or PDTA114TMB equivalent, key selection criteria include built-in bias resistor value (7–13 kΩ), PNP polarity with open R2 configuration, thermal resistance (500 K/W), saturation voltage (−150 mV at IC = −10 mA), and compatibility with ultra-small footprint PCB layouts.
Technical Context
This PNP RET integrates a single bipolar transistor with an on-die 10 kΩ base-input resistor (R1) and no emitter-to-base feedback resistor (R2 = open), simplifying digital logic-level interfacing. Its architecture eliminates external bias components while maintaining DC current gain (hFE ≥ 200 at IC = −1 mA) and low saturation voltage under defined drive conditions.
Designed for operation across −65 °C to +150 °C ambient, it delivers stable performance in automotive body electronics and portable devices. Thermal resistance of 500 K/W (junction-to-ambient, FR4 PCB) and 250 mW total power dissipation at 25 °C define its continuous-duty thermal envelope.
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 rating; supports driving LEDs, small relays, or logic inputs without external current limiting. |
| R1 | 7–13 kΩ - integrated base-input resistor tolerance; sets standard TTL/CMOS-compatible input impedance for direct microcontroller interfacing. |
| VCEsat | −150 mV @ IC = −10 mA, IB = −0.5 mA - low saturation voltage ensures minimal power loss and heat generation in switching mode. |
| fT | 180 MHz - transition frequency confirms suitability for high-speed digital switching up to ~10–20 MHz edge rates. |
| Rth(j-a) | 500 K/W - junction-to-ambient thermal resistance on FR4 PCB; defines derating curve for sustained operation above 25 °C ambient. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
Pinout & Package
DFN1006B-3 (SOT883B) is a 3-terminal, leadless, ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.37 mm, optimized for space-constrained mobile and automotive PCBs. Its low profile and solderable side pads support automated reflow assembly with IPC-compliant footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive (e.g., 3.3 V or 5 V MCU GPIO) without external resistor. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side load connection point; sinks current when active, enabling low-side switching topology. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 10 kΩ ±30 % - eliminates discrete base resistor, reducing BOM count and layout area by one passive component. |
| AEC-Q101 qualification | Automotive-grade reliability - validated for extended temperature range (−65 °C to +150 °C) and mechanical stress per industry standard. |
| Ultra-low package height | 0.37 mm - enables stacking under shields or integration into slim handheld enclosures without mechanical interference. |
| Reduced pick-and-place cost | Single-component placement vs. transistor + resistor - lowers SMT line cycle time and placement error risk. |
| Open R2 configuration | No emitter feedback resistor - simplifies design for basic inverting switch applications where gain stability is not critical. |
Applications
| Automotive Body Control | Mobile LED Backlighting |

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 |
|---|---|---|---|
| PDTC114TMB | NPN complement with identical R1 = 10 kΩ, same DFN1006B-3 package, but opposite polarity and sourcing (not sinking) capability. | Used where active-high drive or low-side switching is preferred; requires inverted logic signal routing. | Select when circuit topology demands NPN configuration or when sharing layout with PDTC114TMB for dual-polarity designs. |
| EMH11T2R | PNP RET in SC-70 package (2.2 × 1.35 × 0.95 mm); R1 = 10 kΩ, VCEO = −50 V, but higher Rth(j-a) (~350 K/W) and larger footprint. | Suitable for less space-constrained boards where thermal margin is prioritized over miniaturization. | Choose when board real estate allows larger package and higher thermal mass improves transient thermal performance. |
Compared with PDTC114TMB, PDTA114TMB offers complementary PNP functionality essential for high-side switching, while EMH11T2R trades size for easier handling and slightly better thermal dissipation-making PDTA114TMB optimal for ultra-dense automotive and mobile PCBs requiring AEC-Q101 compliance.

FAQ
Is PDTA114TMB pin-compatible with other RETs in the DFN1006B-3 package?
Yes-PDTA114TMB uses the standardized DFN1006B-3 (SOT883B) pinout: Pin 1 = input (base), Pin 2 = emitter (GND), Pin 3 = collector (output). This matches all Nexperia RETs in this package, including PDTC114TMB and PDTA124TMB, enabling layout reuse across polarity and resistor-value variants.
What is the maximum operating temperature for continuous use?
PDTA114TMB supports continuous operation up to +150 °C junction temperature. At ambient temperatures above 25 °C, power dissipation must be derated linearly per the 500 K/W thermal resistance-e.g., at 85 °C ambient, max continuous power drops to ~150 mW to maintain Tj ≤ 150 °C.
Can PDTA114TMB replace a standard PNP transistor like BC807 in existing designs?
Yes, with schematic modification: remove the external base resistor and connect the MCU GPIO directly to Pin 1 (input). The integrated R1 = 10 kΩ replaces typical 10–47 kΩ discrete resistors, simplifying layout-but verify logic-high voltage compatibility and required base current for target IC.
Does PDTA114TMB support pulsed operation beyond its DC current rating?
Yes-peak collector current is rated at −100 mA for pulses ≤1 ms (ICM). Pulse operation allows brief surges (e.g., LED flash or solenoid pull-in) exceeding the −100 mA DC limit, provided duty cycle and thermal accumulation remain within the transient thermal impedance curve (Zth(j-a)) shown in Figure 3 of the datasheet.
