Product details
Overview
PDTC114EQC-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It integrates 10 kΩ input and 10 kΩ base-emitter bias resistors, delivers 100 mA output current, achieves ≤100 mV VCE(sat) at IC = 10 mA / IB = 0.5 mA, and is AEC-Q101 qualified for automotive digital switching applications such as IC input control and load switching.
For engineers reviewing the PDTC114EQC-Q datasheet, PDTC114EQC-Q pinout, PDTC114EQC-Q application, or PDTC114EQC-Q equivalent, this page provides verified pin functions, real-world use scenarios in automotive and industrial digital logic interfaces, confirmed thermal derating curves on FR4 PCBs, and validated alternatives with documented R1/R2 and hFE differences.
Technical Context
This RET integrates two precision thin-film resistors (R1 = R2 = 10 kΩ ±30%) directly into the NPN die structure, eliminating external bias components and enabling direct connection to 3.3 V or 5 V logic outputs. Its internal resistor network sets fixed base current under defined VI(on)/VI(off) thresholds, ensuring predictable saturation and cutoff behavior without external design iteration.
The device operates within −55 °C to +150 °C ambient range, supports 0.5 mm max package height for space-constrained layouts, and features side-wettable flanks for automated optical inspection (AOI) of solder joints - critical for high-reliability automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous DC output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| VCE(sat) | ≤100 mV at IC = 10 mA / IB = 0.5 mA - Ensures minimal power loss and heat generation during active switching. |
| R1 / R2 | 10 kΩ / 10 kΩ - Matched internal bias resistors eliminate need for external base resistors in digital interface circuits. |
| hFE | ≥30 at VCE = 5 V, IC = 10 mA - Guarantees reliable current gain for logic-level driven switching without marginal biasing. |
| Tj(max) | 150 °C - Junction temperature limit supporting operation in under-hood automotive environments. |
| Ptot | 450 mW on 70 µm copper FR4 - Defines maximum continuous power dissipation under standard PCB layout conditions. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, ultra-small surface-mount package measuring 1.4 × 1.2 × 0.48 mm with side-wettable flanks for AOI-compatible reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level voltage to enable transistor conduction. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched output node; sinks up to 100 mA when pin 1 is driven above VI(on) threshold (~1.8 V). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates two external SMT resistors per switch channel, reducing BOM count and placement cost. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
| Side-wettable flanks | Enables automated optical inspection of solder fillets on all three terminals, improving first-pass yield in SMT lines. |
| 0.5 mm max height | Supports ultra-thin module designs where Z-height is constrained, e.g., infotainment front panels or ADAS sensor housings. |
| VI(on) / VI(off) | 1.8 V typical turn-on / 0.8 V typical turn-off at IC = 10 mA - ensures clean logic-level interfacing with 3.3 V microcontrollers. |
Applications
| Automotive Door Module Control | Industrial PLC Input Conditioning |
|---|---|
Use Scenario: Switching window lift motor drivers and mirror position sensors in door control units. IC Role / Device Role / Timing Role: Acts as a logic-level interface between MCU GPIO and 12 V loads, providing galvanic isolation via current sinking. Use Value: Reduces component count by replacing BC847B + two 10 kΩ resistors; AEC-Q101 rating ensures compliance with ISO 16750-2. |
Use Scenario: Level-shifting and noise filtering for 24 V dry-contact inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Functions as a digitally controlled input buffer that converts field-side signals to 3.3 V/5 V logic levels. Use Value: Built-in resistor ratio stabilizes input threshold across temperature, eliminating drift-induced false triggers. |
| Consumer Appliance UI Backlight Driver | Medical Diagnostic Equipment Signal Gating |
Use Scenario: Driving LED backlight arrays in smart oven displays and HVAC control panels.

Use Value: 100 mV VCE(sat) minimizes self-heating in sealed enclosures; 0.48 mm profile fits behind thin glass overlays. |
Use Scenario: Enabling/disabling analog signal paths in portable ultrasound front-end modules. IC Role / Device Role / Timing Role: Provides fast, low-leakage signal gating (<100 nA ICEO) between op-amp stages during standby. Use Value: 10 kΩ R1/R2 values ensure sub-µA quiescent current in off-state while maintaining <1 µs turn-on delay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143EQC-Q | R1 = R2 = 4.7 kΩ; hFE ≥30 at IC = 10 mA; lower VI(on) (~1.9 V) | Better suited for 1.8 V logic systems; higher base current draw reduces drive margin in 3.3 V interfaces | Select when interfacing with low-voltage MCUs or when faster turn-on is required despite higher static power |
| BC847B-Q | Discrete NPN BJT; requires external 10 kΩ base resistor; no integrated R2; hFE = 200–450 | Higher gain but demands additional passive component and layout area; not AEC-Q101 qualified | Choose only for non-automotive prototypes where gain variability must be minimized and board space is unconstrained |
Compared with PDTC114EQC-Q, PDTC143EQC-Q offers lower input resistance for improved speed at the cost of higher static current, while BC847B-Q provides wider hFE tolerance but lacks integrated biasing and automotive qualification - making PDTC114EQC-Q optimal for production-grade 3.3 V digital switching where BOM reduction and AEC compliance are mandatory.

FAQ
What is the maximum operating temperature for PDTC114EQC-Q?
The PDTC114EQC-Q has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance Rth(j-a) is 278 K/W on a 70 µm copper FR4 PCB, enabling reliable operation in under-hood automotive environments when mounted per recommended footprint.
Can PDTC114EQC-Q be used with 1.8 V logic inputs?
No - PDTC114EQC-Q has a typical VI(on) of 1.8 V at IC = 10 mA, meaning it may not reliably saturate with 1.8 V logic due to insufficient overdrive. It is optimized for 3.3 V or 5 V CMOS/TTL outputs; for 1.8 V systems, PDTC143EQC-Q (VI(on) ≈ 1.9 V, R1 = 4.7 kΩ) is the appropriate variant.
How does the side-wettable flank design improve manufacturing yield?
The side-wettable flanks on the DFN1412D-3 package allow automated optical inspection (AOI) systems to verify solder joint formation on all three terminals - especially the center GND pad - without X-ray. This eliminates hidden voids and cold-solder defects common in leadless packages, increasing first-pass yield in high-volume SMT lines.
Is there a PNP counterpart to PDTC114EQC-Q?
Yes - PDTA114EQC-Q is the direct PNP complement, featuring identical 10 kΩ R1/R2 values, −50 V VECO, −100 mA output current, and matching DFN1412D-3 packaging. It shares the same AEC-Q101 qualification and thermal characteristics, enabling symmetrical high-side/low-side switching designs.
