Product details
Overview
PDTC114EQC from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless SMD package with side-wettable flanks. It integrates 10 kΩ input and 10 kΩ emitter-base bias resistors, delivers 100 mA output current, exhibits 30× DC current gain at 10 mA collector current, and operates with 100 mV collector-emitter saturation voltage - used for digital switching of IC inputs and low-power load control in space-constrained consumer and industrial PCBs.
For engineers reviewing the PDTC114EQC datasheet, PDTC114EQC pinout, PDTC114EQC application, or PDTC114EQC equivalent, this page provides verified pin functions, real-world switching performance metrics, AOI-compatible packaging details, and validated alternatives for BC847-series replacement in digital logic interface circuits.
Technical Context
This RET integrates two precision thin-film resistors (R1 = R2 = 10 kΩ ±30%) directly into the NPN die structure, eliminating external base bias components. Its internal resistor network enables direct TTL/CMOS-level drive without pull-up or current-limiting resistors.
The device operates as a saturated switch with guaranteed VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA, and supports off-state input voltage up to +40 V while maintaining IEBO ≤ 400 µA - enabling robust noise immunity in noisy digital environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; supports 3.3 V/5 V/12 V logic-level switching with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic gate inputs. |
| R1 / R2 | 10 kΩ / 10 kΩ - Integrated base and emitter resistors eliminate external components and reduce BOM count by one resistor pair. |
| hFE | 30 - Minimum DC current gain at VCE = 5 V, IC = 10 mA; ensures reliable saturation with standard logic drive levels. |
| VCE(sat) | 100 mV - Confirmed maximum saturation voltage at IC = 10 mA / IB = 0.5 mA; minimizes power loss and self-heating during on-state operation. |
| VI(on) | 1.8 V - Typical on-state input voltage at VCE = 0.3 V, IC = 10 mA; compatible with 3.3 V CMOS and 5 V TTL logic thresholds. |
| VI(off) | 0.8 V - Maximum off-state input voltage at VCE = 5 V, IC = 100 µA; ensures clean turn-off under weak pull-down or leakage conditions. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, ultra-small leadless plastic package measuring 1.4 × 1.2 × 0.48 mm with side-wettable flanks for automated optical inspection (AOI) of solder joints and 0.5 mm profile height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level drive; internal R1 connects this pin to transistor base; no external base resistor required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; internal R2 connects base to this pin for bias stabilization. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or logic input); sinks current to GND when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates need for two external resistors, reducing PCB area and assembly steps in digital interface circuits. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on bottom-terminated packages, improving manufacturing yield. |
| Low 0.5 mm profile | Supports ultra-thin end equipment (e.g., wearables, slim displays) where Z-height is constrained. |
| 100 mA continuous output | Drives multiple logic inputs or small indicator loads without external current amplification. |
| Guaranteed VCE(sat) ≤ 100 mV | Reduces conduction losses below 1 mW at 10 mA, critical for battery-powered and thermally sensitive designs. |
Applications
| LED Indicator Control | Digital Input Conditioning |
|---|---|
Use Scenario: Driving status LEDs on microcontroller GPIO lines with limited current sourcing capability. IC Role / Device Role / Timing Role: NPN switch sinking LED cathode current to ground; replaces discrete transistor + two resistors. Use Value: Reduces component count by three parts per channel and eliminates manual resistor selection for consistent brightness. |
Use Scenario: Level-shifting and debouncing push-button signals before MCU interrupt inputs. IC Role / Device Role / Timing Role: Digital buffer isolating noisy mechanical switch bounce from sensitive digital inputs. Use Value: Built-in R1/R2 provide stable biasing and noise filtering without external RC networks. |
| Logic-Level Load Switching | BC847 Series Replacement |
Use Scenario: Enabling/disabling low-power peripherals (e.g., sensors, UART transceivers) via MCU GPIO. IC Role / Device Role / Timing Role: High-side or low-side load switch controlled by 3.3 V logic; operates in saturation region. Use Value: 100 mV VCE(sat) limits voltage drop across switch, preserving supply headroom for downstream circuitry. |
Use Scenario: Drop-in upgrade path for legacy BC847-based designs requiring reduced assembly cost and smaller footprint. IC Role / Device Role / Timing Role: Direct functional replacement in digital switching applications with identical pinout mapping. Use Value: Eliminates two external bias resistors and reduces PCB area by >60% versus SO-23 package alternatives. |
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 | R1 = R2 = 4.7 kΩ; lower input resistance increases base drive sensitivity but reduces noise immunity. | Better suited for weak-drive sources (e.g., open-drain outputs), less tolerant of leakage-induced false triggering. | Select when driving from low-current sources or needing faster turn-on response at expense of off-state margin. |
| PDTC124EQC | R1 = R2 = 22 kΩ; higher input resistance improves off-state noise rejection but requires stronger logic drive. | Preferred for high-noise environments (e.g., motor control boards) where VI(off) ≥ 0.8 V must be exceeded reliably. | Choose when interfacing with 5 V CMOS or buffered logic with ≥ 4 mA drive capability and EMI-prone layouts. |
Compared with PDTC143EQC, PDTC114EQC offers balanced drive strength and noise immunity for general-purpose 3.3 V logic; versus PDTC124EQC, it lowers minimum required input voltage for reliable turn-on while retaining adequate off-state margin.

FAQ
What is the maximum operating temperature for PDTC114EQC?
The PDTC114EQC has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −55 °C to +150 °C. Thermal resistance from junction to ambient is 278 K/W on a 70 µm copper FR4 PCB, enabling reliable operation at full 100 mA load up to +85 °C ambient with proper layout.
Can PDTC114EQC be used in place of BC847B in existing designs?
Yes - PDTC114EQC serves as a functional replacement for BC847B in digital switching roles, provided the application uses the transistor as a saturated switch with external base resistors. Its integrated 10 kΩ resistors eliminate those components, requiring only layout revision to accommodate the DFN1412D-3 footprint and removal of two resistors per channel.
Does PDTC114EQC support automatic optical inspection (AOI)?
Yes - the DFN1412D-3 (SOT8009) package features side-wettable flanks, allowing AOI systems to inspect solder joint quality on the exposed metal sidewalls. This capability is confirmed in Nexperia's official package documentation and supported by standard reflow footprints published in the datasheet.
What is the typical transition frequency (fT) of PDTC114EQC?
The typical transition frequency is 230 MHz at VCE = 5 V, IC = 10 mA, and f = 100 MHz. While optimized for DC/low-frequency switching, this fT value confirms sufficient bandwidth for fast digital edges (<10 ns rise times) and avoids unintended oscillation in properly decoupled PCB layouts.
