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 bias resistors R1 = 10 kΩ and R2 = 47 kΩ. It functions as a 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 device serves as a space- and cost-optimized alternative to discrete BJT + resistor networks-particularly where board area, assembly count, and signal-level switching reliability are critical.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors: R1 (input bias resistor, 10 kΩ nominal) connects base to input, and R2 (base-emitter feedback resistor, 47 kΩ) enables self-biasing and stable saturation. The R2/R1 ratio of 4.7 ensures predictable turn-on behavior across temperature.
Designed for DC-coupled digital switching, it operates with VI(on) ≤ 0.8 V at IC = 1 mA and VI(off) ≥ 0.5 V at IC = 100 µA, supporting direct interfacing with 3.3 V and 5 V logic families without external level-shifting components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports rail-to-rail switching in 24 V industrial control systems. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 10 kΩ ±30% - Input bias resistor value; sets base current for predictable turn-on with standard CMOS/TTL drive levels. |
| R2/R1 | 4.7 - Fixed internal feedback ratio; ensures stable saturation and reduces sensitivity to transistor hFE variation. |
| VCE(sat) | ≤100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| fT | 230 MHz - Transition frequency of the embedded transistor; enables fast edge response for digital signals up to ~10–20 MHz. |
| Ptot | 200 mW at Tamb = 25 °C - Total power dissipation limit on FR4 PCB; defines thermal derating envelope for continuous operation. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-pin, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body; optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to logic signal source via R1; accepts 0–40 V input while limiting base current automatically. |
| 2 | Ground (emitter) | Common reference node; ties emitter directly to system ground-no external emitter resistor required. |
| 3 | Output (collector) | Switches load between VCC and ground; supports sink-current configuration for active-low logic interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 network | Eliminates need for two external bias resistors-reduces BOM count by 2 parts and saves >0.5 mm² PCB area per instance. |
| Guaranteed R2/R1 ratio | 4.7 ±20% ensures consistent saturation behavior across production lots and temperature (−40 °C to +125 °C). |
| Low VCE(sat) | ≤100 mV at rated current enables <10 mW conduction loss-critical for thermally constrained modules and battery-powered nodes. |
| ESD robustness | HBM rating >2 kV (per JEDEC JESD22-A114); withstands handling and board-level ESD events without protection diodes. |
Applications
| Industrial Digital Control | Logic-Level Signal Translation |
|---|---|
Use Scenario: Driving optocoupler inputs in PLC I/O modules with 24 V supply and microcontroller GPIO. IC Role / Device Role / Timing Role: NPN switch sinking current from optocoupler LED anode to ground; provides galvanic isolation interface. Use Value: Eliminates discrete resistor network, reducing component count and improving long-term reliability under vibration and thermal cycling. |
Use Scenario: Converting 3.3 V MCU outputs to 5 V-tolerant enable signals for legacy peripherals. IC Role / Device Role / Timing Role: Level-shifting switch with defined VI(on)/VI(off) thresholds; ensures clean logic transitions without timing skew. Use Value: Delivers sub-100 ns propagation delay and eliminates need for dedicated level translators or pull-up resistors. |
| LED Driver for Status Indication | Microcontroller GPIO Load Switching |
Use Scenario: Driving multi-color status LEDs on HMI panels with shared 5 V rail and limited GPIO drive strength. IC Role / Device Role / Timing Role: Constant-current sink switch; limits LED current via VCE(sat) and series resistance selection. Use Value: Enables precise brightness control using only one external current-limiting resistor per LED, simplifying firmware PWM implementation. |
Use Scenario: Enabling/disabling power to sensor modules or communication transceivers via MCU-controlled enable lines. IC Role / Device Role / Timing Role: High-side or low-side load switch depending on connection topology; provides clean on/off control with minimal leakage. Use Value: Reduces quiescent current to <100 nA in off-state (ICEO ≤ 5 µA at 150 °C), extending battery life in always-on monitoring devices. |
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; VI(on) ≈ 1.0 V typical. | Better suited for 5 V logic with weak drive strength; less suitable for 3.3 V CMOS due to higher turn-on threshold. | Select when interfacing with older 5 V microcontrollers or open-drain drivers requiring higher input resistance. |
| BC847B | Discrete NPN BJT (no built-in resistors); hFE = 200–450; requires external RB and RBE for biasing. | Offers wider gain range and higher fT (300 MHz), but increases design complexity and layout area. | Choose only when fine-grained gain tuning or analog amplification is needed-otherwise RET offers superior integration. |
Compared with PDTC124YU, PDTC114YU delivers lower VI(on) and better compatibility with 3.3 V logic; versus BC847B, it trades gain flexibility for reduced bill-of-materials and improved manufacturing yield in digital switching roles.

FAQ
Can PDTC114YU be used in linear amplifier configurations?
No. PDTC114YU is designed exclusively for digital switching operation. Its integrated resistors fix the base bias point, preventing adjustable DC operating point selection. The datasheet specifies no linear-region parameters such as output conductance or distortion metrics, and its hFE tolerance (100 min) is optimized for saturated switching-not analog gain stability.
What is the maximum ambient temperature for continuous 100 mA operation?
At 100 mA, the device dissipates up to ~10 mW (VCE(sat) × IC). Using the derating curve in Figure 1, full 200 mW rating applies only below 25 °C ambient. For continuous 100 mA, junction temperature remains within 150 °C limit up to ~125 °C ambient on standard FR4 PCB-verified by thermal modeling per Table 6 (Rth(j-a) = 625 K/W).
Does PDTC114YU support bidirectional signal routing?
No. PDTC114YU is a unidirectional NPN switch configured for sink-current operation only. Pin 3 (collector) must be connected to the positive side of the load; pin 2 (emitter) is internally tied to ground reference. Reverse connection violates absolute maximum ratings (e.g., VEBO = 6 V) and risks permanent damage.
How does the R2/R1 ratio affect switching speed?
The R2/R1 ratio of 4.7 provides optimal charge extraction during turn-off, reducing storage time. Measured toff is typically <100 ns at IC = 10 mA-faster than discrete BC847 + resistor networks due to matched on-chip resistor temperature coefficients and minimized parasitic inductance.
