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. It functions as a single-chip digital switch for IC input control and load switching in space-constrained industrial PCBs.
For engineers reviewing the PDTC114EU datasheet, PDTC114EU pinout, PDTC114EU application, or PDTC114EU equivalent, key selection criteria include built-in R1/R2 ratio (1.0 typ), VI(on) (1.8–2.5 V), VCE(sat) (≤150 mV @ IC = 10 mA), hFE ≥30, and SC-70 thermal resistance (625 K/W).
Technical Context
This RET integrates a monolithic NPN transistor with two precision silicon resistors on a single die. Its internal topology uses R1 connected between base and input terminal, and R2 between base and emitter, enabling direct logic-level drive without external bias components.
The device operates in saturation/switching mode only - not linear amplification - with guaranteed VI(off) ≤ 0.8 V (ensuring reliable turn-off at TTL/CMOS low levels) and VI(on) ≥ 1.8 V (compatible with 3.3 V and 5 V logic families). Thermal derating follows a defined curve down to 0 mW at 150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; enables use in 24 V industrial control rails with safety margin. |
| IO | 100 mA - continuous DC output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - integrated base-input resistor; eliminates need for external pull-up/pull-down and simplifies PCB layout. |
| R2/R1 | 1.0 (0.8–1.2) - tightly controlled internal resistor ratio; ensures stable biasing and predictable switching thresholds. |
| VCE(sat) | ≤150 mV @ IC = 10 mA, IB = 0.5 mA - low saturation voltage minimizes power loss and self-heating during on-state operation. |
| hFE | ≥30 @ VCE = 5 V, IC = 5 mA - minimum DC current gain ensures robust saturation under worst-case temperature and process variation. |
| Ptot | 200 mW @ Tamb = 25 °C on FR4 PCB - defines maximum steady-state power handling before thermal shutdown or degradation. |
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 height. Designed for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Connects to logic signal source; internally tied to R1 top terminal and transistor base. |
| 2 | Ground (emitter node) | Common reference node; connects to R2 bottom terminal and transistor emitter; must be tied to system ground. |
| 3 | Output (collector node) | Switched high-side output; connects to load (e.g., LED anode or relay coil); sinks current when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (10 kΩ) + R2 (10 kΩ) eliminates 2 external resistors and reduces BOM count by one component. |
| Logic-compatible input threshold | VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V ensure clean switching with 3.3 V CMOS and 5 V TTL outputs. |
| Low saturation loss | VCE(sat) ≤150 mV at 10 mA enables <1.5 mW conduction loss - critical for thermally constrained modules. |
| Thermal reliability | Rth(j-a) = 625 K/W on standard FR4; supports continuous operation up to 100 °C ambient with proper layout. |
| Automotive-grade variant available | PDTC114YU (−Q qualified) offers identical electrical specs with AEC-Q101 qualification for automotive applications. |
Applications
| Industrial PLC I/O Modules | Automotive Body Control Units |
|---|---|
|
Use Scenario: Level-shifting and isolation of microcontroller GPIO pins driving 24 V solenoid valves or indicator LEDs. IC Role / Device Role / Timing Role: Digital switch interfacing low-voltage MCU logic to higher-voltage loads; no timing function. Use Value: Reduces board area by eliminating discrete base resistors and improves assembly yield via fewer pick-and-place operations. |
Use Scenario: Controlling interior lighting circuits (dome lights, map lights) in non-safety-critical vehicle zones. IC Role / Device Role / Timing Role: Load switch for 12 V DC loads; operates in static on/off state with no PWM or high-frequency switching. Use Value: Enables compact, cost-effective implementation of multiple independent lighting channels using a single footprint. |
| Consumer Appliance Control Boards | IoT Sensor Node Power Management |
|
Use Scenario: Enabling/disabling auxiliary functions (e.g., buzzer, display backlight) in white goods based on MCU command. IC Role / Device Role / Timing Role: Low-power digital enable switch; activated only during brief operational windows. Use Value: Cuts standby current by replacing always-on discrete transistors with a single RET that draws zero base current in off-state. |
Use Scenario: Managing power to peripheral sensors (e.g., humidity, motion) in battery-powered edge nodes to extend runtime. IC Role / Device Role / Timing Role: High-side load switch controlling VDD to sensor ICs; duty-cycled per measurement interval. Use Value: Achieves sub-100 nA off-state leakage (ICEO ≤ 5 µA at 150 °C) ensuring multi-year battery life in sleep mode. |
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 → R2/R1 ≈ 2.1; lower input sensitivity; higher VI(on) (2.4–3.2 V) | Better suited for 5 V logic with higher noise immunity; less suitable for 3.3 V systems near VI(on) min. | Select when driving from 5 V microcontrollers with marginal noise margins or where reduced base current draw is prioritized. |
| BC847B | Discrete NPN BJT with no integrated resistors; requires external RB and RE; hFE = 200–450; VCE(sat) = 600 mV @ 10 mA | Higher gain but larger solution size and higher conduction loss; requires design validation of bias network stability. | Choose only if variable gain or analog operation is required; otherwise PDTC114EU delivers superior integration and efficiency. |
Compared with PDTC124EU, PDTC114EU provides tighter R2/R1 matching and lower VI(on) for 3.3 V compatibility; versus BC847B, it eliminates two passives and cuts VCE(sat) by 75 %, reducing thermal load in dense layouts.

FAQ
Is PDTC114EU suitable for automotive applications?
No - PDTC114EU is not automotive-qualified. Per Nexperia's revision history (v.15, Oct 2024), this part was explicitly changed to non-automotive qualification. For automotive use, select the pin-compatible PDTC114YU, which carries AEC-Q101 qualification and undergoes extended temperature and reliability testing.
What is the maximum allowable continuous current at 85 °C ambient?
At Tamb = 85 °C, the power derating curve (Fig. 1) shows Ptot ≈ 120 mW. With VCE(sat) ≤150 mV, maximum continuous IC = Ptot/VCE(sat) ≈ 120 mW / 0.15 V = 800 mA - but the absolute maximum IO remains 100 mA per limiting values. Therefore, 100 mA is the hard ceiling regardless of temperature.
Can PDTC114EU be used in linear amplifier configurations?
No - PDTC114EU is designed exclusively for digital switching operation. Its internal resistor network fixes the base bias point, preventing adjustable Q-point selection. The datasheet specifies no hFE linearity, frequency response beyond fT = 230 MHz (for switching speed), or small-signal parameters required for amplification.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 (±0.2) sets the internal feedback strength, stabilizing the base voltage during switching transitions and minimizing sensitivity to variations in hFE. This ensures consistent VI(on) and VI(off) across process and temperature, unlike discrete designs where resistor tolerances and transistor gain spread cause threshold drift.
