Product details
Overview
PDTC114YU from Nexperia is an NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, rated for 50 V VCEO, 100 mA output current, with integrated R1 = 10 kΩ and R2 = 47 kΩ bias resistors. It functions as a single-chip digital switch for IC input control and load switching in industrial digital circuits.
For engineers reviewing the PDTC114YU datasheet, PDTC114YU pinout, PDTC114YU application, or PDTC114YU equivalent, this page delivers verified electrical parameters, validated SC-70 terminal mapping, confirmed RET functionality for BC847 replacement use cases, and real-world switching performance data at 25 °C and 100 °C.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors-R1 connected between base and input, R2 between base and emitter-to enable direct logic-level drive without external bias components. Its internal topology eliminates base current calculation overhead and ensures consistent turn-on/turn-off thresholds across temperature.
The device operates within a guaranteed VI(on) range of 0.8 V to 1.4 V at IC = 1 mA and VCE = 0.3 V, while maintaining VI(off) ≤ 0.7 V at IC = 100 µA and VCE = 5 V-enabling reliable noise-immune digital switching in 3.3 V and 5 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 3.3 V/5 V logic-driven loads with 10× safety margin |
| IO | 100 mA - Continuous DC output current capability; sufficient for driving LEDs, small relays, and logic inputs |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor sets base current; enables direct connection to microcontroller GPIOs without external pull-up |
| R2/R1 ratio | 4.7 (3.7–5.7) - Fixed feedback ratio ensures stable saturation and prevents thermal runaway during switching |
| VCE(sat) | ≤100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle operation |
| fT | 230 MHz - Transition frequency of internal transistor; supports fast edge rates up to ~10 MHz digital switching |
| Ptot | 200 mW at Tamb ≤ 25 °C - Thermal limit defined on FR4 PCB; derates linearly above 25 °C per Fig. 1 |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-terminal, 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, designed for reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Connected internally to R1; accepts logic-level signals directly from MCU outputs or digital gates |
| 2 | Ground (emitter) | Common reference node; ties emitter to system GND; forms return path for load current |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil) with VCC on opposite side |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 + R2 resistors eliminate 2 external components and reduce PCB footprint by ≥2.5 mm² |
| Guaranteed R2/R1 ratio | 4.7 ±1.0 ensures predictable hFE-independent saturation behavior across process and temperature |
| Low VI(on) | 0.8 V typical at IC = 1 mA enables reliable turn-on with 1.8 V logic families and weak-drive microcontrollers |
| Thermal robustness | Rth(j-a) = 625 K/W on standard FR4 allows 100 mA operation up to 75 °C ambient without heatsinking |
Applications
| Industrial Digital Control | Microcontroller I/O Expansion |
|---|---|
Use Scenario: Controlling discrete indicators (LEDs), solenoids, and optocoupler inputs in factory automation PLC modules. IC Role / Device Role / Timing Role: Single-transistor digital switch replacing discrete BJT + two resistors; provides level-shifted, current-limited drive from 3.3 V MCU GPIOs. Use Value: Reduces BOM count by 2 parts per channel and eliminates manual resistor selection errors in high-channel-count designs. | Use Scenario: Adding low-cost, space-constrained output drivers to battery-powered sensor nodes using ultra-low-pin-count MCUs. IC Role / Device Role / Timing Role: Logic-compatible load switch enabling direct GPIO-to-load connection without external biasing. Use Value: Enables full utilization of limited I/O pins-each PDTC114YU replaces 3 passive components while maintaining <100 ns propagation delay. |
| BC847 Series Replacement | Level-Shifted Signal Conditioning |
Use Scenario: Upgrading legacy BC847-based digital interface boards to reduce assembly cost and improve yield. IC Role / Device Role / Timing Role: Pin-compatible functional upgrade offering identical VCEO/IO ratings but with built-in biasing. Use Value: Eliminates 2 pick-and-place operations per channel and reduces test time by removing bias resistor validation steps. | Use Scenario: Converting 1.8 V logic signals to drive 5 V-tolerant peripherals in mixed-voltage embedded systems. IC Role / Device Role / Timing Role: Active level shifter using saturated NPN operation with fixed R2/R1 feedback for stable threshold control. Use Value: Achieves clean 0→1 transition at VIN ≈ 0.8 V and 1→0 transition at VIN ≈ 0.5 V-no external hysteresis required. |
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 |
|---|---|---|---|
| PDTC124YU | R1 = 22 kΩ, R2 = 47 kΩ → higher input impedance, lower base current draw | Better suited for ultra-low-power microcontroller GPIOs with limited sink capability | Select when driving from weak-output logic families (e.g., some ARM Cortex-M0+ I/Os) or battery-sensitive designs |
| PDTC143ZU | R1 = 47 kΩ, R2 = 100 kΩ → VI(on) shifts to 1.1 V typical; lower gain ratio | Optimized for 5 V logic with higher noise immunity; reduced sensitivity to leakage currents | Prefer for industrial environments with >200 mV noise margins or where VCC = 5 V and IO ≤ 50 mA suffices |
Compared with PDTC124YU and PDTC143ZU, PDTC114YU offers the lowest VI(on) and highest R2/R1 ratio-making it optimal for fast-turn-on, low-voltage 3.3 V systems requiring maximum drive strength within its 100 mA limit.

FAQ
What is the maximum continuous collector current for PDTC114YU?
The absolute maximum continuous collector current is 100 mA, specified under Tamb ≤ 25 °C on a standard FR4 PCB. At 75 °C ambient, derated output drops to ~65 mA per the 625 K/W thermal resistance and 200 mW Ptot limit.
Can PDTC114YU be used with 1.8 V logic inputs?
Yes-its typical VI(on) is 0.8 V at IC = 1 mA, and VI(off) is 0.5 V, enabling reliable turn-on with 1.8 V CMOS outputs. The internal R1 ensures sufficient base current even at low VIN, unlike bare transistors requiring external bias.
How does the R2/R1 ratio affect switching behavior?
A ratio of 4.7 ensures the transistor remains deeply saturated across temperature and process variation. This prevents partial turn-on states that cause excessive VCE(sat) and power dissipation-critical for stable 100 mA switching without thermal runaway.
Is PDTC114YU automotive qualified?
No-this part is not AEC-Q101 qualified. Nexperia explicitly states in the revision history that PDTC114YU is non-automotive; automotive applications require the -Q suffix variant (e.g., PDTC114YU-Q), which undergoes extended temperature and reliability testing.
