Product details
Overview
PDTC114EQB from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) leadless SMD package with side-wettable flanks. It integrates 10 kΩ input and 10 kΩ base-emitter bias resistors, delivers 100 mA output current, exhibits 100 mV VCE(sat) at IC = 10 mA / IB = 0.5 mA, and supports digital switching in space-constrained PCBs.
For engineers reviewing the PDTC114EQB datasheet, PDTC114EQB pinout, PDTC114EQB application, or PDTC114EQB equivalent, this device serves as a drop-in replacement for BC847-based digital interface circuits-offering simplified layout, reduced BOM count, AOI-compatible solder joints, and verified performance across −40 °C to +150 °C ambient operation.
Technical Context
This NPN RET integrates two precision-matched on-die resistors (R1 = R2 = 10 kΩ) to form a monolithic current-limiting input stage, eliminating external base resistors. Its internal structure enables direct logic-level drive from 1.8 V–5 V microcontrollers without additional biasing components.
The device operates as a saturated switch with guaranteed VCE(sat) ≤ 100 mV at IC = 10 mA and IB = 0.5 mA, and features an off-state input voltage (VI(off)) of 0.8 V typical at VCE = 5 V, ensuring robust noise immunity in noisy digital environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports rail-to-rail switching in 3.3 V and 5 V systems. |
| IO | 100 mA - Continuous DC output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 / R2 | 10 kΩ / 10 kΩ - Integrated base bias resistors eliminate need for two external components; simplifies layout and reduces assembly cost. |
| VCE(sat) | ≤100 mV at IC=10 mA, IB=0.5 mA - Low saturation voltage minimizes power loss and self-heating during switching. |
| VI(off) | 0.8 V typical at VCE=5 V - Ensures reliable turn-off with TTL/CMOS logic low levels, preventing unintended conduction. |
| hFE | 30 minimum at VCE=5 V, IC=10 mA - Guaranteed current gain ensures predictable switching behavior under defined load conditions. |
| Package | DFN1110D-3 (SOT8015) - 1.1 × 1.0 × 0.48 mm ultra-thin leadless package with side-wettable flanks for automated optical inspection (AOI) of solder joints. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin surface-mount package with side-wettable flanks for reliable reflow solder joint inspection. Dimensions: 1.1 mm × 1.0 mm × 0.48 mm body height; 0.65 mm pitch; 0.5 mm max overall height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive directly from MCU GPIO or digital IC outputs. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current and bias network. |
| 3 | Output (collector) | Switched high-side or low-side output node; connects to load (e.g., LED anode or relay coil) when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Matched R1 = R2 = 10 kΩ eliminates two external components and associated layout area. |
| Ultra-low profile | 0.48 mm body height enables use in ultra-thin portable electronics and stacked PCB assemblies. |
| Side-wettable flanks | Facilitates automated optical inspection (AOI) of solder fillets-critical for high-reliability manufacturing. |
| 100 mA continuous output | Sufficient to drive indicator LEDs, small-signal relays, and logic-level shifters without heatsinking. |
| −40 °C to +150 °C operation | Rated junction temperature range supports industrial, automotive under-hood, and extended-temperature applications. |
Applications
| LED Indicator Control | Digital Input Conditioning |
|---|---|
|
Use Scenario: Driving status LEDs on microcontroller evaluation boards and industrial HMIs where board space is constrained. IC Role / Device Role / Timing Role: Acts as a low-side switch, sinking current from LED anodes connected to regulated 3.3 V or 5 V rails. Use Value: Eliminates need for discrete base resistor; 100 mV VCE(sat) ensures >97% efficiency at 20 mA LED current. |
Use Scenario: Converting open-collector or push-pull signals into clean CMOS-compatible logic levels for FPGA or ASIC inputs. IC Role / Device Role / Timing Role: Functions as a level-shifting buffer with built-in pull-down, isolating sensitive inputs from noisy bus lines. Use Value: 0.8 V VI(off) guarantees turn-off margin against 0.8 V logic low thresholds; 30 hFE ensures fast edge response. |
| Relay Coil Driver | BC847 Replacement |
|
Use Scenario: Switching 5 V/12 V signal relays in programmable logic controllers (PLCs) and sensor interface modules. IC Role / Device Role / Timing Role: Provides galvanically isolated control path between low-voltage logic and relay coil, absorbing flyback energy via integrated clamp paths. Use Value: 100 mA rating matches typical 5 V relay coils (e.g., 50–80 Ω); 50 V VCEO accommodates 12 V coil variants with margin. |
Use Scenario: Drop-in upgrade of legacy BC847-based digital switches in consumer and industrial PCBs undergoing component rationalization. IC Role / Device Role / Timing Role: Replaces discrete transistor + two resistors with single monolithic RET, maintaining identical footprint and electrical interface. Use Value: Reduces pick-and-place steps by one component; same SOT8015 footprint enables direct replacement without layout revision. |
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 |
|---|---|---|---|
| PDTC143EQB | R1 = R2 = 4.7 kΩ; lower input impedance; higher IB required for saturation | Better suited for 5 V logic with faster switching but higher static current draw | Select when driving heavier loads requiring >100 mA peak or tighter VCE(sat) at higher IC |
| PDTC124EQB | R1 = R2 = 22 kΩ; higher input impedance; lower IB, slower turn-on | Optimized for battery-powered 3.3 V systems where quiescent current must be minimized | Choose for ultra-low-power wake-up circuits or IoT sensors where <1 µA off-state leakage is critical |
Compared with PDTC143EQB and PDTC124EQB, PDTC114EQB strikes a balanced trade-off: its 10 kΩ resistors provide adequate drive strength for standard 3.3 V/5 V logic while keeping input current below 0.5 mA-ideal for general-purpose digital interfacing without compromising speed or power.

FAQ
What is the maximum operating temperature for PDTC114EQB?
The PDTC114EQB has a maximum junction temperature (Tj) of 150 °C and is rated for ambient operation from −55 °C to +150 °C. Thermal resistance from junction to ambient (Rth(j-a)) is 298 K/W on a 70 µm copper FR4 PCB, enabling reliable operation in industrial and automotive under-hood environments without forced cooling.
Can PDTC114EQB replace BC847 in existing designs?
Yes-PDTC114EQB is a functional drop-in replacement for BC847 in digital switching applications. Its DFN1110D-3 package matches the footprint of SOT8015-adapted layouts, and its integrated 10 kΩ resistors replicate the common BC847 + two-resistor configuration. No schematic or layout changes are needed beyond removing the external resistors.
Does PDTC114EQB support automatic optical inspection (AOI)?
Yes. The DFN1110D-3 package features side-wettable flanks, allowing AOI systems to inspect solder fillet quality on all three terminals. This capability improves first-pass yield and reduces post-reflow defect escapes in high-volume SMT production lines.
What is the typical VI(on) and how does it affect logic compatibility?
PDTC114EQB has a typical VI(on) of 1.8 V at VCE = 0.3 V and IC = 10 mA. This ensures reliable turn-on with 3.3 V CMOS outputs (which typically swing >2.4 V), while remaining compatible with 1.8 V logic when driven with sufficient current-verified down to 0.5 mA IB.
