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 operating up to 150 °C junction temperature - 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 behavior, bias resistor tolerance (±30%), and direct alternatives to BC847-based designs with reduced BOM count.
Technical Context
This RET integrates a monolithic NPN transistor with two precision thin-film resistors on a single die: R1 connects base to input, R2 connects base to emitter, enabling single-resistor drive logic-level switching without 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 and IC = 5 mA, supports VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V across −40 °C to +100 °C, and maintains R2/R1 ratio within 0.8–1.2 - ensuring stable turn-on/turn-off thresholds under temperature variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum - defines safe collector-emitter blocking voltage in open-base switching configurations |
| IO | 100 mA continuous output - supports driving small relays, LEDs, or logic inputs without external current limiting |
| R1 | 10 kΩ ±30% - sets input current limit and logic-high threshold when driven from 3.3 V or 5 V microcontrollers |
| R2/R1 | 1.0 ±0.2 - ensures predictable base current division and stable saturation behavior across temperature |
| VCE(sat) | ≤150 mV at IC=10 mA/IB=0.5 mA - guarantees low conduction loss and minimal self-heating during sustained ON-state |
| Ptot | 200 mW at Tamb ≤25 °C - defines maximum power dissipation on FR4 PCB with standard footprint before derating applies |
| Tj(max) | 150 °C - enables operation in under-hood or industrial enclosures without active cooling |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, tin-plated terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base via R1) | Logic-level signal entry point; internal R1 limits base current and eliminates need for external series resistor |
| 2 | Ground (emitter) | Common reference node for both transistor emitter and R2; must be connected to system GND for proper biasing |
| 3 | Output (collector) | Switched high-side load connection point; sinks current to GND when active, supports up to 100 mA DC |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (10 kΩ) + R2 (10 kΩ) eliminates 2 external resistors and reduces layout area by >40% |
| Guaranteed saturation | VCE(sat) ≤150 mV at IC/IB = 20 ensures reliable low-loss switching even with marginal drive strength |
| Wide temperature range | Operates from −65 °C to +150 °C ambient - qualified for industrial and non-automotive under-hood applications |
| Low input threshold | VI(on) ≤2.5 V at 25 °C enables direct interface with 3.3 V logic without level-shifting circuitry |
| Thermal robustness | Rth(j-a) = 625 K/W on FR4 PCB allows 200 mW dissipation at 25 °C ambient before reaching Tj = 150 °C |
Applications
| Microcontroller GPIO Expansion | Industrial Sensor Interface |

IC Role / Device Role / Timing Role: Cost-optimized digital switch delivering consistent gain (hFE ≥30) and saturation performance across production lots. Use Value: Reduces pick-and-place cost by one placement step and eliminates resistor solder joint failure mode in high-volume manufacturing. |
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 |
|---|---|---|---|
| PDTC124EU | R1 = 22 kΩ, R2 = 47 kΩ - higher input impedance, lower base current, slower turn-on | Better suited for high-impedance MCU outputs or battery-powered systems requiring <5 µA input leakage | Select when drive source has weak current capability or ultra-low standby power is prioritized over switching speed |
| BC847B | Discrete NPN BJT with no integrated resistors - requires external 10 kΩ base resistor and lacks R2 feedback | Offers higher hFE (200–450) but demands additional passive components and layout area | Choose only if precise gain control or linear amplification is required - not recommended for simple switching due to added BOM and assembly cost |
Compared with PDTC124EU, PDTC114EU delivers faster switching and higher drive strength due to lower R1; compared with BC847B, it reduces total solution size by 35% and eliminates resistor placement risk while maintaining identical SOT323 footprint compatibility.

FAQ
What is the maximum allowable input voltage (VI) for PDTC114EU?
The absolute maximum input voltage is specified as −10 V to +40 V. This rating accounts for transient overshoot and ESD events; for continuous operation, VI should remain within the VI(on)/VI(off) range (1.8–2.5 V ON, 0.8–1.1 V OFF) to ensure reliable switching without forward-biasing the base-emitter junction beyond its 10 V VEBO limit.
Can PDTC114EU be used in high-frequency switching applications?
With a typical transition frequency fT of 230 MHz, PDTC114EU supports switching up to ~10–20 MHz in optimized layouts. However, its primary design intent is digital logic-level switching-not RF amplification-so parasitic capacitance (Cc = 2.5 pF) and package inductance limit practical edge rates in high-speed PWM circuits.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 ensures stable base current division, preventing latch-up and improving noise immunity. A ratio near 1.0 provides symmetrical turn-on/turn-off thresholds, while deviations outside this range increase sensitivity to temperature drift and reduce margin against false triggering in noisy environments.
Is PDTC114EU qualified for automotive applications?
No. Per Revision History v.15 (20241009), PDTC114EU is explicitly marked as non-automotive qualified. For automotive use, Nexperia offers the PDTC114YU-Q variant, which undergoes AEC-Q101 stress testing and includes extended temperature validation and PPAP documentation.
