Product details
Overview
PDTC114ET from Nexperia is an NPN resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with 50 V VCEO, 100 mA IO, and integrated bias resistors R1 = R2 = 10 kΩ. It replaces discrete BJT + two resistors in load control, IC input driving, and automotive/industrial digital logic interfaces.
For engineers reviewing the PDTC114ET datasheet, PDTC114ET pinout, PDTC114ET application, or PDTC114ET equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, real-world switching use cases, and confirmed alternatives to BC847-based designs.
Technical Context
The PDTC114ET integrates a monolithic NPN transistor with two precision on-die bias resistors-R1 (input resistor) and R2 (base-emitter feedback resistor)-configured as a single-input, ground-referenced switch. Its fixed R2/R1 ratio of 1.0 ±0.2 enables predictable turn-on/off thresholds without external component tuning.
It operates as a saturated switch under DC conditions with VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA, and supports digital logic-level drive (VI(on) = 1.8–2.5 V, VI(off) = 0.8–1.1 V), making it compatible with 3.3 V and 5 V microcontroller GPIOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial bus and 12 V automotive loads. |
| IO | 100 mA - Continuous output current rating; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor sets base current; eliminates need for external pull-up/pull-down. |
| R2/R1 | 1.0 (0.8–1.2) - Feedback resistor ratio ensures stable saturation and noise immunity in digital switching. |
| VCE(sat) | ≤ 100 mV at IC = 10 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle operation. |
| hFE | ≥ 30 at IC = 5 mA - Guaranteed current gain ensures reliable switching even at elevated temperatures (−40 °C to 100 °C). |
| Ptot | 250 mW at Tamb = 25 °C - Power dissipation limit defines thermal design margin on standard FR4 PCBs. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), optimized for automated placement and reflow soldering per IPC-7351B footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Single logic-level input node connected internally to R1; accepts 3.3 V/5 V TTL/CMOS signals directly. |
| 2 | Ground (emitter) | Emitter tied to system GND; provides common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil, IC input) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 + R2 resistors eliminate 2 external components and reduce PCB area by >30% vs. discrete BJT + resistors. |
| Digital logic compatibility | VI(on)/VI(off) thresholds match standard 3.3 V and 5 V logic families, enabling direct MCU GPIO interfacing without level-shifting. |
| Thermal robustness | Rth(j-a) = 500 K/W on FR4 PCB allows continuous 100 mA operation up to 75 °C ambient without heatsinking. |
| Automotive-grade reliability | Qualified per AEC-Q101 (non-automotive version noted; -Q variant available for automotive use). |
| Standard marking | %16 code (site-dependent prefix) enables traceability and automated optical inspection during assembly. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V MCU outputs in industrial HMI panels. IC Role / Device Role / Timing Role: Digital switch controlling LED anode connection to 5 V rail; operates in static on/off mode. Use Value: Eliminates need for external base resistor and reduces BOM count by one part per LED channel. | Use Scenario: Extending limited GPIO count on STM32F4 microcontrollers to control multiple solenoid valves. IC Role / Device Role / Timing Role: Level-translating buffer and current amplifier for low-drive-strength MCU pins. Use Value: Enables direct 100 mA valve coil drive without additional driver ICs or discrete transistor stages. |
| Logic-Level Translator | Industrial Sensor Interface |
Use Scenario: Converting open-drain I²C pull-up signals (3.3 V) to 5 V-compatible inputs for legacy controllers. IC Role / Device Role / Timing Role: Active pull-up switch translating logic states between voltage domains. Use Value: Provides clean edge transitions with <100 ns propagation delay and no shoot-through risk. | Use Scenario: Isolating noisy 24 V proximity sensor outputs from sensitive PLC input modules. IC Role / Device Role / Timing Role: Voltage-level clamped digital interface protecting downstream logic from transients. Use Value: Built-in 10 kΩ input resistor limits surge current; VEBO = 10 V withstands common-mode spikes. |
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,215 | Discrete NPN BJT requiring two external 10 kΩ bias resistors; no integrated R2 feedback path. | Higher component count and layout complexity; less noise-immune in EMI-prone environments. | Select when existing designs already use BC847 footprint and require minimal schematic change. |
| PDTA114ET,215 | PNP complement with identical R1/R2 values and SOT23 package; VCEO = −50 V, IO = −100 mA. | Used for high-side switching where load connects to ground; not interchangeable in same circuit topology. | Select for complementary high-side control in dual-rail or H-bridge configurations. |
Compared with BC847B, the PDTC114ET reduces bill-of-materials and improves noise immunity via integrated R2 feedback; versus PDTA114ET, it serves low-side switching roles only and cannot substitute in high-side positions without circuit redesign.

FAQ
What is the maximum operating temperature for continuous 100 mA switching?
The PDTC114ET supports continuous 100 mA output current up to 75 °C ambient temperature on a standard FR4 PCB with 35 µm copper, based on its 250 mW Ptot rating and 500 K/W thermal resistance. At 100 °C ambient, derated current drops to ~65 mA per the published power derating curve.
Can PDTC114ET replace BC847 in existing PCB layouts?
No - although electrically compatible, PDTC114ET uses SOT23 pinout (1=Input, 2=GND, 3=Output), while BC847B in SOT23 has 1=E, 2=B, 3=C. Direct replacement requires PCB redesign or adapter board due to incompatible pin mapping and internal resistor topology.
Is PDTC114ET qualified for automotive applications?
The PDTC114ET (215) is non-automotive qualified per its 2022 datasheet revision. For automotive use, Nexperia offers the PDTC114ET-Q series, which undergoes AEC-Q101 stress testing and includes extended temperature range validation and enhanced process controls.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 ±0.2 provides negative feedback that stabilizes base current during temperature variation and improves noise immunity. It ensures consistent VI(on) and VI(off) thresholds across process corners, reducing false triggering in electrically noisy industrial environments.
