Product details
Overview
PDTC114EU from Nexperia is an NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, featuring integrated 10 kΩ input bias resistor (R1) and 10 kΩ emitter feedback resistor (R2), 50 V VCEO, 100 mA output current, and 150 mV VCEsat at IC = 10 mA / IB = 0.5 mA - used for digital switching in automotive control modules and industrial I/O interfaces.
For engineers reviewing the PDTC114EU datasheet, PDTC114EU pinout, PDTC114EU application, or PDTC114EU equivalent, key selection criteria include built-in R1/R2 ratio tolerance (0.8–1.2), VI(on)/VI(off) thresholds across temperature (−40 °C to +100 °C), SC-70 thermal resistance (625 K/W on FR4), and compatibility with BC847/BC857 replacement in low-power logic-level switching.
Technical Context
This RET integrates a monolithic NPN transistor with two precision thin-film resistors on a single die: R1 connects base to input terminal, R2 connects base to emitter, enabling direct TTL/CMOS-compatible drive without external bias components. It operates as a saturated switch with guaranteed hFE ≥ 30 at IC = 5 mA and VCE = 5 V.
The device exhibits stable DC current gain (hFE) over −40 °C to +100 °C, with VCEsat ≤ 150 mV and transition frequency fT = 230 MHz (typ.) - confirming suitability for medium-speed digital switching up to ~10 MHz edge rates while maintaining low power dissipation (Ptot = 200 mW at Tamb ≤ 25 °C).
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 with margin. |
| IO | 100 mA - continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ range) - sets input current threshold; enables direct connection to 3.3 V/5 V logic without series resistor. |
| R2/R1 | 1.0 (0.8–1.2) - defines internal feedback ratio; ensures stable saturation and predictable turn-off behavior. |
| VCEsat | ≤150 mV at IC=10 mA/IB=0.5 mA - guarantees low conduction loss and minimal self-heating in switching mode. |
| hFE | ≥30 at VCE=5 V, IC=5 mA - ensures reliable forced beta operation under standard digital drive conditions. |
| fT | 230 MHz (typ.) - indicates high-frequency capability of the underlying transistor; supports fast edge transitions in digital control paths. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, FR4-compatible footprint with 35 µm copper and tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Connects to logic signal source; internally tied to R1 top terminal - accepts 0–40 V input with VI(on) ≈ 1.8–2.5 V. |
| 2 (GND) | Ground (emitter node) | Emitter reference and return path; internally connected to R2 bottom terminal and transistor emitter - must be tied to system ground. |
| 3 (O) | Output (collector node) | Switched load connection; collector of internal NPN transistor - sinks current when active, open-circuit when off. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (10 kΩ) + R2 (10 kΩ) eliminates 2 external resistors and reduces PCB area by >1.5 mm² per channel. |
| Logic-level compatible drive | VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V enable direct interface with 3.3 V LVTTL and 5 V CMOS without level-shifting. |
| Thermal robustness | Rth(j-a) = 625 K/W on standard FR4 allows 100 mA switching at ambient up to +75 °C without heatsinking. |
| Automotive-grade reliability | Qualified per AEC-Q101 (non-automotive version noted in revision history; Q-grade alternatives available). |
| High-speed switching | fT = 230 MHz supports <10 ns rise/fall times in optimized layouts - suitable for PWM dimming and digital I/O buffering. |
Applications
| Industrial PLC Digital I/O | Automotive Body Control Module |
|---|---|
Use Scenario: Isolating microcontroller GPIO pins from 24 V sensor inputs and relay drivers in factory automation cabinets. IC Role / Device Role / Timing Role: NPN switch providing level-shifted, current-sinking interface between 3.3 V MCU and industrial field devices. Use Value: Eliminates discrete base-resistor network, reducing BOM count by 2 parts per channel and improving assembly yield on high-density I/O cards. | Use Scenario: Driving LED status indicators and small solenoids in door module ECUs operating from 12 V battery rail. IC Role / Device Role / Timing Role: Low-power digital switch controlling indicator loads with fast on/off response and low standby leakage. Use Value: VI(off) ≤ 1.1 V ensures full cutoff at cold cranking voltages (6–8 V), preventing false activation during engine start. |
| Consumer Appliance Control Board | IoT Sensor Node Interface |
Use Scenario: Enabling/disabling buzzer, display backlight, and motor driver enable lines in smart home appliances. IC Role / Device Role / Timing Role: General-purpose logic-controlled load switch with integrated biasing for space-constrained PCBs. Use Value: SC-70 footprint saves >0.8 mm² vs. SOT23 equivalents, critical for compact white-goods control boards. | Use Scenario: Interfacing ultra-low-power MCUs (e.g., ARM Cortex-M0+) with external sensors requiring active pull-up/pull-down. IC Role / Device Role / Timing Role: Bidirectional signal conditioning element acting as programmable current sink/source for I²C pull-ups or analog sensor biasing. Use Value: R2/R1 = 1.0 provides symmetrical input hysteresis, improving noise immunity on long sensor traces in noisy environments. |
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 BJT without integrated resistors; requires external RB and RE; hFE = 200–450 (higher gain but no built-in bias control). | Used where adjustable base current or variable saturation depth is required; not drop-in for RET-based schematics. | Select when precise IB/IC ratio tuning is needed or when RET thermal derating is insufficient for high-ambient designs. |
| PDTA114EU,115 | PNP counterpart with identical R1/R2 values (10 kΩ/10 kΩ); complementary polarity; same SC-70 package and pinout (reversed terminal roles). | Required for high-side switching or inverted logic configurations where sourcing current is necessary. | Select for complementary pair design or when interfacing with open-collector outputs needing active pull-up. |
Compared with BC847B and PDTA114EU, the PDTC114EU uniquely delivers fixed, production-trimmed biasing in a miniature package - reducing layout complexity and qualification effort for cost-sensitive, high-volume digital switching where consistent saturation and guaranteed VI thresholds are prioritized over gain variability or polarity flexibility.

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 reverse-bias conditions. In normal operation, VI should remain within VI(on) (1.8–2.5 V) and VI(off) (0.8–1.1 V) thresholds to ensure reliable switching; exceeding +40 V risks permanent damage to the integrated R1 resistor or base-emitter junction.
Can PDTC114EU replace BC847 in existing designs without circuit modification?
No - PDTC114EU is not a direct drop-in replacement for BC847. Unlike the discrete BC847, it integrates R1 and R2, altering the base drive topology. Direct substitution would short the base through R2 and prevent proper turn-on. A redesign is required to remove external bias resistors and reassign connections to the RET's I/GND/O terminals.
What is the thermal resistance (Rth(j-a)) when mounted on a 2-layer PCB with 1 oz copper?
The datasheet specifies Rth(j-a) = 625 K/W for FR4 PCB with single-sided 35 µm (1 oz) copper, tin-plated, and standard SOT323 footprint. On a 2-layer board with internal ground plane, actual Rth(j-a) improves to ~420–480 K/W depending on via count and copper area - enabling higher continuous current or extended ambient temperature operation.
Is PDTC114EU qualified for automotive applications?
No - the PDTC114EU is explicitly marked as non-automotive qualified in the 2024 revision history. For automotive use, Nexperia offers the PDTC114YQ (AEC-Q101 qualified) variant. Using PDTC114EU in automotive systems voids warranty and violates functional safety requirements due to lack of stress testing per AEC standards.
