Product details
Overview
PDTC114EU from Nexperia is an NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, integrating 10 kΩ input bias resistor (R1) and 10 kΩ emitter feedback resistor (R2), rated for 50 V VCEO, 100 mA output current, and 200 mW power dissipation at Tamb ≤ 25 °C; used for digital switching in automotive and industrial control interfaces.
For engineers reviewing the PDTC114EU datasheet, PDTC114EU pinout, PDTC114EU application, or PDTC114EU equivalent, this page delivers verified pin functions, real-world switching use cases, thermal derating data, and validated alternatives to BC847/BC857 series in low-complexity digital logic interface designs.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors: R1 connects base to input, R2 connects base to emitter, enabling single-resistor drive and eliminating external bias networks. It operates as a saturated switch with guaranteed VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA.
The device exhibits hFE ≥ 30 at VCE = 5 V, IC = 5 mA, and supports VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V across temperature, ensuring robust noise margin in 3.3 V and 5 V logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables safe operation in 24 V industrial bus and 12 V automotive signal lines. |
| IO | 100 mA - Continuous output current rating; sufficient to drive LED indicators, small relays, and logic-level inputs without external buffering. |
| R1 | 10 kΩ (7–13 kΩ range) - Input bias resistor value; sets base current for predictable saturation with standard CMOS/TTL logic outputs. |
| R2/R1 ratio | 1.0 (0.8–1.2) - Matches emitter feedback to input resistance; ensures stable turn-off and suppresses leakage-induced false triggering. |
| VCE(sat) | ≤150 mV at IC=10 mA/IB=0.5 mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| Ptot | 200 mW at Tamb ≤ 25 °C - Total power dissipation limit on FR4 PCB; requires derating above 25 °C per 625 K/W junction-to-ambient thermal resistance. |
| fT | 230 MHz - Transition frequency of internal transistor; supports fast edge rates in digital enable/disable signals up to ~10 MHz. |
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) | Connected internally to R1; accepts logic-level voltage (VI(on)/VI(off)) to control transistor conduction state. |
| 2 | Ground (emitter) | Common reference node for both R1 and R2; serves as current return path and defines output reference for collector load. |
| 3 | Output (collector) | Switched high-side output node; sinks up to 100 mA when saturated; connects to load between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (10 kΩ) + R2 (10 kΩ) eliminates 2 external resistors, reducing BOM count and layout area by >30% vs discrete BC847 + bias pair. |
| Digital switching optimization | Guaranteed VI(on) ≤ 2.5 V and VI(off) ≥ 0.8 V at 25 °C ensure reliable activation/deactivation with 3.3 V LVTTL and 5 V CMOS outputs. |
| Thermal robustness | Rth(j-a) = 625 K/W on standard FR4; allows sustained 100 mA operation below 100 °C junction temperature at ambient ≤ 50 °C. |
| Automotive-capable construction | Non-automotive qualified per v.15 revision, but built on Nexperia's AEC-Q101-compatible process; suitable for industrial control and non-safety-critical automotive modules. |
Applications
| LED Indicator Control | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Driving status LEDs on industrial HMIs where MCU GPIOs are limited and cannot source/sink >20 mA directly. IC Role / Device Role / Timing Role: Digital switch that translates low-current MCU output into 100 mA sink capability for high-brightness LEDs. Use Value: Eliminates need for discrete transistor + two bias resistors; reduces footprint by 45% and assembly cost by one pick-and-place step. |
Use Scenario: Enabling additional digital outputs from resource-constrained microcontrollers (e.g., Cortex-M0+, PIC16F) in sensor nodes. IC Role / Device Role / Timing Role: Level-shifting and current-boosting buffer for GPIOs driving optocouplers or small solenoids. Use Value: Supports clean 10 MHz toggle rates (fT = 230 MHz) with <150 mV VCE(sat), minimizing voltage drop and self-heating during burst-mode operation. |
| Logic-Level Signal Translation | Low-Power Load Switching |
|
Use Scenario: Interfacing 3.3 V FPGA I/O banks to 5 V legacy peripherals requiring TTL-compatible input thresholds. IC Role / Device Role / Timing Role: Active-low level shifter with defined VI(on)/VI(off) windows ensuring noise-immune transition between logic families. Use Value: VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V provide >0.7 V noise margin against ground bounce and supply ripple in mixed-voltage systems. |
Use Scenario: Power gating of auxiliary circuits (e.g., sensors, RF modules) in battery-powered IoT devices to extend runtime. IC Role / Device Role / Timing Role: Low-leakage (ICEO ≤ 5 µA at 150 °C) high-side switch controlled by sleep-mode MCU pins. Use Value: ICEO ≤ 5 µA at elevated temperature ensures <1 µA standby current per channel, critical for multi-year coin-cell operation. |
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 |
|---|---|---|---|
| BC847B,115 | Discrete NPN transistor (no integrated resistors); requires external RB and RE; hFE = 200–450; VCEO = 45 V. | Higher gain and lower VCE(sat) (~100 mV), but adds 2 passive components and layout complexity. | Select when precise bias tuning or higher speed (>300 MHz fT) is required; avoid if BOM simplification is priority. |
| PDTC124EU,115 | Same SOT323 RET architecture but with R1 = 22 kΩ, R2 = 47 kΩ (R2/R1 ≈ 2.1); VI(on) = 2.2–3.0 V; lower IO = 80 mA. | Optimized for higher-impedance logic drivers (e.g., open-drain I²C pull-ups); less suitable for direct 3.3 V CMOS drive. | Select when interfacing with weak-sourcing logic or needing higher off-state noise immunity; not drop-in for PDTC114EU's 10 kΩ bias profile. |
Compared with BC847B and PDTC124EU, PDTC114EU offers optimal balance of 10 kΩ input impedance, 100 mA drive, and 3.3 V logic compatibility-making it the preferred choice for cost-sensitive, space-constrained digital interface applications where component count reduction is critical.

FAQ
What is the maximum continuous collector current for PDTC114EU?
The PDTC114EU is rated for 100 mA continuous output current (IO) under normal operating conditions. This rating assumes Tamb ≤ 25 °C and proper PCB thermal relief; derating applies above 25 °C per the 625 K/W junction-to-ambient thermal resistance curve shown in Figure 1 of the datasheet.
Can PDTC114EU be used with 3.3 V logic inputs?
Yes. PDTC114EU has a guaranteed VI(on) range of 1.8–2.5 V and VI(off) of 0.8–1.1 V at 25 °C, providing >0.7 V noise margin with standard 3.3 V CMOS outputs. Its 10 kΩ R1 ensures sufficient base current for full saturation even with 3.3 V drive, confirmed in Figure 5 of the datasheet.
Is PDTC114EU automotive-qualified?
No. Per Revision v.15 (October 2024), PDTC114EU is explicitly marked as non-automotive qualified. Nexperia provides separate -Q qualified variants (e.g., PDTC114EU-Q) for automotive applications; this part meets industrial reliability standards but lacks AEC-Q101 stress testing and qualification documentation.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 ± 0.2 ensures strong negative feedback during turn-off, suppressing leakage-induced false conduction. A ratio near unity improves immunity to temperature drift and collector leakage (ICEO ≤ 5 µA at 150 °C), making the device stable across –40 °C to +125 °C operating range as shown in Figures 3–6.
