Product details
Overview
PDTC114ET from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in SOT23 package, integrating R1 = 10 kΩ and R2 = 10 kΩ bias resistors. It functions as a digital switch for IC input control and low-power load switching in industrial and automotive electronics, with VCE(sat) ≤ 100 mV at IC = 10 mA and IB = 0.5 mA.
For engineers reviewing the PDTC114ET datasheet, PDTC114ET pinout, PDTC114ET application, or PDTC114ET equivalent, this part serves as a drop-in replacement for BC847-based digital interface circuits-offering reduced BOM count, simplified layout, and guaranteed bias network matching without external resistor selection.
Technical Context
The PDTC114ET integrates an NPN bipolar transistor with two monolithically embedded silicon resistors: R1 (input bias) and R2 (base-emitter feedback), forming a single-input, grounded-emitter switch topology. Its R2/R1 ratio of 1.0 ± 0.2 ensures stable saturation across temperature and process variation.
Designed for DC-coupled digital logic interfacing, it operates with VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V at 25 °C, enabling direct connection to 3.3 V and 5 V CMOS/TTL outputs without level-shifting. The built-in resistors eliminate base floating risk and guarantee turn-off under high-impedance drive conditions.
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 supply rails. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor sets base current; enables ~0.3 mA drive from 3.3 V logic with ~100 µA margin. |
| R2/R1 | 1.0 (0.8–1.2) - Feedback-to-input resistor ratio; ensures reliable turn-off by shunting leakage current away from base. |
| VCE(sat) | ≤100 mV at IC=10 mA/IB=0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| fT | 230 MHz - Transition frequency of internal transistor; supports fast edge response in digital switching up to ~10 MHz. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Thermal limit on FR4 PCB; derates linearly above 25 °C per 500 K/W junction-to-ambient resistance. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch); thermally optimized for reflow soldering on standard FR4 PCBs with 35 µm copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level voltage to activate the transistor; no external base resistor required. |
| 2 | GND (emitter) | Emitter tied directly to ground reference; provides return path for load current and R2 feedback current. |
| 3 | Output (collector) | Switched output node; connects to load (e.g., LED anode or relay coil); sinks current when active. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias network | Monolithic R1 = 10 kΩ + R2 = 10 kΩ eliminates discrete resistor placement, reducing PCB area by ≥2.5 mm² per instance. |
| Guaranteed turn-off behavior | R2 shunts base leakage and noise, ensuring VBE remains below 0.5 V during logic-low states-even with high-impedance drivers. |
| Reduced assembly cost | Single-component replacement for BC847 + two 0402/0603 resistors cuts pick-and-place cycles and inventory SKUs by 67%. |
| Thermal robustness | 150 °C max junction temperature and 500 K/W Rth(j-a) enable operation in sealed enclosures up to 85 °C ambient. |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
|
Use Scenario: Level-shifting and signal conditioning between 3.3 V microcontroller GPIO and 12 V sensor pull-up networks. IC Role / Device Role / Timing Role: Digital switch isolating MCU pins from higher-voltage domains while preserving logic polarity. Use Value: Eliminates need for external level translators or dual-supply buffers; reduces component count and board space in compact sensor nodes. |
Use Scenario: Driving indicator LEDs and small solenoids in door module PCBs where space and reliability are critical. IC Role / Device Role / Timing Role: Load switch providing controlled current sink with predictable turn-on/turn-off thresholds. Use Value: Built-in resistors prevent latch-up during ESD transients and ensure fail-safe off-state under open-circuit MCU pin faults. |
| Consumer Appliance Control Panel | IoT Edge Node Power Management |
|
Use Scenario: Enabling/disabling backlight segments and buzzer drivers in white-goods HMI boards using 5 V logic. IC Role / Device Role / Timing Role: High-side switch controller (with external PNP or PMOS) or low-side load driver. Use Value: VI(on)/VI(off) specs match TTL thresholds, enabling direct drive from legacy ASICs without redesigning gate drive circuitry. |
Use Scenario: Managing power to peripheral sensors (e.g., temperature, humidity) in battery-powered smart meters. IC Role / Device Role / Timing Role: Enable switch controlling VCC rail to downstream analog front-end ICs. Use Value: Ultra-low ICBO (≤100 nA) and ICEO (≤5 µA at 150 °C) minimize standby current leakage, extending battery life beyond 10 years. |
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 requiring external 10 kΩ base resistor; no R2 feedback path; hFE = 200–450 vs. fixed RET gain. | Lacks guaranteed turn-off; susceptible to false triggering from EMI or floating inputs; requires additional footprint and layout effort. | Select only when precise hFE control or analog amplification is needed; not recommended for digital switching where reliability is prioritized. |
| PDTA114ET,215 | PNP complement with identical R1/R2 values; VECO = 50 V; same SOT23 package but inverted pinout (Pin 1 = emitter, Pin 2 = collector, Pin 3 = base). | Used for high-side switching or complementary logic stages; incompatible pin-for-pin with PDTC114ET due to reversed terminal assignment. | Choose for sourcing current instead of sinking; verify PCB layout compatibility-requires separate footprint or mirrored placement. |
Compared with BC847B and PDTA114ET, the PDTC114ET delivers deterministic digital switching behavior through integrated biasing, reduces design validation time by eliminating resistor tolerance stack-up analysis, and improves field reliability in noisy environments where discrete base resistors may degrade or lift.

FAQ
What is the maximum safe operating voltage for PDTC114ET in continuous DC switching?
The absolute maximum collector-emitter voltage (VCEO) is 50 V, verified under open-base conditions per IEC 60134. For reliable long-term operation, Nexperia recommends limiting VCE to ≤40 V in designs with transient overvoltage risks, especially in automotive 12 V systems where load-dump spikes can exceed 40 V.
Can PDTC114ET be used with 1.8 V logic inputs?
No-its VI(on) minimum is 1.8 V at 25 °C, but typical VI(on) rises to ~2.5 V at -40 °C and drops to ~1.8 V at 100 °C. At 1.8 V drive, turn-on margin becomes marginal below 0 °C; use only with 3.3 V or 5 V logic families. For 1.8 V systems, consider NX30P0107UK or similar low-threshold alternatives.
How does the built-in R2 resistor improve reliability compared to a discrete base resistor?
R2 provides a defined discharge path from base to emitter, preventing charge accumulation that could cause unintended conduction during ESD events or MCU reset glitches. Discrete solutions lack guaranteed R2 matching, risking incomplete turn-off if external resistor tolerances exceed ±20%, whereas PDTC114ET guarantees R2/R1 = 1.0 ± 0.2 across temperature and lot variations.
Is PDTC114ET qualified for automotive applications?
No-per Nexperia's 2022 revision history, PDTC114ET is explicitly marked "non-automotive qualified" and lacks AEC-Q101 stress testing. For automotive use, select the -Q qualified variant PDTC114ET,115 (if available) or consult Nexperia's automotive RET portfolio such as PBSS4041T or PUMH10.
