Product details
Overview
PDTC114EU-Q from Nexperia is an AEC-Q101-qualified 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 IO, and 150 mV VCEsat at IC = 10 mA / IB = 0.5 mA - used for digital load switching in automotive control modules.
For engineers reviewing the PDTC114EU-Q datasheet, PDTC114EU-Q pinout, PDTC114EU-Q application, or PDTC114EU-Q equivalent, key selection criteria include built-in resistor ratio (R2/R1 = 1.0 ± 0.2), AEC-Q101 qualification, SC-70 thermal resistance (625 K/W), and VI(on)/VI(off) thresholds for reliable logic-level interfacing with MCUs and ASICs.
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 without external bias network. It operates as a saturated switch with guaranteed turn-on at VI(on) ≤ 2.5 V and turn-off at VI(off) ≥ 0.8 V (Tamb = 25 °C).
The device delivers hFE ≥ 30 at VCE = 5 V / IC = 5 mA, supports 100 mA continuous output current, and maintains stable performance across −40 °C to +150 °C junction temperature range - validated per AEC-Q101 stress test requirements including HTGB, HTRB, and ESD-HBM ≥ 8 kV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; enables use in 24 V automotive systems with margin. |
| IO | 100 mA - continuous output current rating; sufficient for driving LEDs, relays, and logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - input bias resistor; sets base current for logic-compatible drive without external components. |
| R2/R1 | 1.0 ± 0.2 - matched internal resistor ratio; ensures predictable saturation and noise immunity in digital switching. |
| VCEsat | 150 mV max at IC = 10 mA / IB = 0.5 mA - low saturation voltage minimizes power loss and self-heating. |
| VI(on) | 1.8–2.5 V - minimum input voltage to guarantee turn-on; compatible with 3.3 V and 5 V CMOS/TTL logic families. |
| fT | 230 MHz - transition frequency of the embedded transistor; supports fast edge response in pulse-width modulation circuits. |
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, FR4 PCB mountable with standard reflow footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level signal to activate transistor. |
| 2 | Ground (emitter) | Emitter terminal tied to system ground; R2 connects between Pin 1 and Pin 2. |
| 3 | Output (collector) | Switched high-side output node; sinks up to 100 mA to ground when active. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| Integrated R1 + R2 network | Eliminates need for two external bias resistors, reducing BOM count and PCB area by ≥3 components per switch node. |
| Logic-level compatible VI(on)/VI(off) | Guaranteed turn-on below 2.5 V and turn-off above 0.8 V enables direct interface with 3.3 V microcontrollers. |
| Low thermal resistance | Rth(j-a) = 625 K/W on FR4 PCB - supports 100 mA operation without heatsink in ambient ≤ 85 °C. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |
|---|---|
|
Use Scenario: Driving door lock actuators and interior lighting loads in 12 V/24 V vehicle systems. IC Role / Device Role / Timing Role: NPN RET configured as low-side switch controlled by MCU GPIO. Use Value: AEC-Q101 compliance ensures reliability over 15-year vehicle lifetime; built-in resistors prevent solder joint fatigue from component count reduction. |
Use Scenario: Isolating field-side 24 V DC outputs from controller logic in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Discrete-level digital output stage providing galvanically isolated switching via optocoupler-driven base input. Use Value: 100 mA rating supports direct drive of small solenoids and indicator LEDs; SC-70 footprint enables dense I/O module layouts. |
| Consumer Appliance Motor Control | Medical Diagnostic Equipment Interface |
|
Use Scenario: Enabling/disabling small DC brush motors in smart home appliances (e.g., coffee grinders, air purifiers). IC Role / Device Role / Timing Role: Logic-controlled power switch placed between microcontroller and motor driver IC enable line. Use Value: VI(on) ≤ 2.5 V allows direct connection to 3.3 V ARM Cortex-M0+ GPIO; 150 mV VCEsat limits heat generation during PWM duty cycles. |
Use Scenario: Level-shifting and buffering sensor status signals (e.g., temperature, pressure) to microcontroller inputs in portable diagnostic devices. IC Role / Device Role / Timing Role: Digital buffer isolating sensitive analog front-end from noisy digital subsystems. Use Value: R2/R1 = 1.0 ratio provides stable hysteresis-free switching; 2.5 pF Cc minimizes signal integrity impact on 100 kHz status updates. |
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-Q | R1 = 22 kΩ, R2 = 47 kΩ → R2/R1 ≈ 2.1; lower base current, higher noise immunity | Better suited for high-impedance MCU outputs or noisy environments where reduced IB improves EMI rejection | Select when driving from weak-sourcing GPIO or where VI(on) margin must exceed 3.0 V |
| BC847BW | Discrete NPN BJT (no built-in resistors); requires external RB and RE; hFE = 110–800 | Offers wider gain range and adjustable biasing but increases component count and layout complexity | Choose only if variable gain, analog amplification, or custom bias optimization is required |
Compared with PDTC124EU-Q, PDTC114EU-Q provides lower input impedance and faster switching due to higher base drive; versus BC847BW, it trades design flexibility for BOM simplification and AEC-Q101 assurance - making it optimal for cost-sensitive, high-volume automotive digital switching.

FAQ
Is PDTC114EU-Q pin-compatible with BC847BW?
No - PDTC114EU-Q uses SOT323 (SC-70) with Pin 1 = Input, Pin 2 = GND, Pin 3 = Output; BC847BW in SOT323 has Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. The RET integrates bias resistors and requires no external components, whereas BC847BW needs two external resistors for equivalent function.
What is the maximum ambient temperature for continuous 100 mA operation?
At 100 mA IO, Ptot ≈ 15 mW (100 mA × 150 mV). With Rth(j-a) = 625 K/W, ΔT = 9.4 K; thus, Tamb can reach 140.6 °C before hitting Tj = 150 °C limit. However, derating per Figure 1 reduces usable current to ~65 mA at 85 °C ambient on standard FR4 PCB.
Does PDTC114EU-Q support PWM switching at 20 kHz?
Yes - fT = 230 MHz and typical ton/toff < 5 ns (per Nexperia characterization) ensure clean 20 kHz square-wave switching with minimal distortion. The low Cc = 2.5 pF and fast VI(on)/VI(off) transitions prevent shoot-through in half-bridge configurations when used as gate driver stage.
Can PDTC114EU-Q be used in high-humidity under-hood automotive environments?
Yes - the SOT323 package is qualified to MSL1 per J-STD-020, and the device passes AEC-Q101 humidity testing (H3TRB: 1000 h at 85 °C/85% RH). Its molded compound and leadframe plating provide robust protection against condensation and salt mist exposure in engine bay applications.
