Product details
Overview
PDTC114YU-QF 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 47 kΩ feedback resistor (R2), 50 V VCEO, 100 mA IO, and optimized for digital switching in automotive control modules.
For engineers reviewing the PDTC114YU-QF datasheet, PDTC114YU-QF pinout, PDTC114YU-QF application, or PDTC114YU-QF equivalent, this part serves as a drop-in replacement for BC847-Q series in load-switching and IC-input driving roles where built-in biasing reduces PCB area and assembly cost.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors-R1 connected between base and input, R2 between base and emitter-enabling single-pin logic-level drive without external bias network. It operates as a saturated switch under IC/IB = 20 condition with VCE(sat) ≤ 100 mV at 5 mA.
The device complies with AEC-Q101 stress testing for automotive use, supports ambient temperatures from −65 °C to +150 °C, and delivers stable hFE ≥ 100 at 5 mA/5 V while maintaining VI(on) = 0.8–1.4 V and VI(off) = 0.5–0.7 V across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current rating; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor sets base current; eliminates need for external pull-up/pull-down. |
| R2/R1 ratio | 4.7 (3.7–5.7) - Feedback ratio stabilizes operating point; improves noise immunity and thermal stability. |
| VCE(sat) | ≤ 100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss in switching mode. |
| hFE | ≥ 100 at VCE = 5 V, IC = 5 mA - Ensures reliable turn-on with low drive current, reducing MCU GPIO loading. |
| fT | 230 MHz - Transition frequency of internal transistor; supports fast edge response in digital switching. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-lead, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body, FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Logic-level signal entry point; connects internally to R1 and R2 junction-no external base connection required. |
| 2 | Ground (emitter) | Emitter terminal tied to system GND; provides return path for load current and bias network. |
| 3 | Output (collector) | Switched high-side output node; sinks up to 100 mA when driven high at Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (10 kΩ) and R2 (47 kΩ) eliminate two external resistors and associated layout area. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD per AEC standard. |
| Low VCE(sat) | ≤ 100 mV ensures <1 mW conduction loss at 10 mA, critical for thermally constrained modules. |
| Small-footprint SOT323 | 0.95 mm height and 2.5 mm² board area support high-density routing in ADAS and body-control ECUs. |
| Wide temperature range | Operates from −65 °C to +150 °C junction temperature, matching under-hood environmental requirements. |
Applications
| Automotive Door Module Control | Industrial PLC Digital Input Conditioning |
|---|---|
Use Scenario: Switching window lift motor drivers and mirror position sensors in door control units. IC Role / Device Role / Timing Role: NPN RET acts as level-shifting interface between 3.3 V microcontroller GPIOs and 12 V loads. Use Value: Eliminates discrete base-resistor network, reducing BOM count by two parts and improving solder joint reliability. | Use Scenario: Converting 24 V industrial field signals into clean 3.3 V logic levels for FPGA or ARM-based controllers. IC Role / Device Role / Timing Role: Digital input buffer with built-in hysteresis via R2 feedback, rejecting line noise up to ±1 V. Use Value: VI(off) ≤ 0.7 V and VI(on) ≥ 0.8 V ensure robust noise margin without external Schmitt trigger. |
| LED Indicator Driver | Microcontroller GPIO Load Switch |
Use Scenario: Driving status LEDs on dashboard clusters and infotainment panels. IC Role / Device Role / Timing Role: Constant-current sink switch with fixed gain and low saturation voltage. Use Value: VCE(sat) ≤ 100 mV limits LED forward-voltage drop impact, preserving brightness consistency across supply variation. | Use Scenario: Enabling/disabling peripheral ICs (e.g., CAN transceivers, sensor interfaces) using MCU GPIOs. IC Role / Device Role / Timing Role: High-side enable switch controlled by active-high logic signal. Use Value: Built-in R1/R2 ensures guaranteed turn-on at 3.3 V logic, avoiding marginal biasing seen with BC847-Q variants. |
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 |
|---|---|---|---|
| PDTC124YU-Q | R1 = 22 kΩ, R2 = 47 kΩ → higher input impedance, lower base current | Better suited for ultra-low-power wake-up circuits where IIN < 50 μA is required | Select when drive source has limited current capability or higher noise immunity is needed. |
| BC847B-Q | Discrete NPN transistor without integrated resistors; requires external RB and RE | Offers adjustable gain and bias but increases component count and layout complexity | Choose only if variable hFE tuning or non-standard switching thresholds are required. |
Compared with PDTC124YU-Q and BC847B-Q, PDTC114YU-Q provides optimal balance of drive strength (100 μA typical IIN), compactness, and automotive qualification-making it preferred for cost-sensitive, space-constrained digital switching where fixed biasing suffices.

FAQ
What is the maximum continuous collector current for PDTC114YU-QF?
The absolute maximum continuous collector current is 100 mA, as specified in the Limiting Values table. Derating applies above Tamb = 25 °C per the power derating curve (Ptot = 200 mW at 25 °C, decreasing linearly to zero at 150 °C junction temperature). Operation beyond this rating risks permanent damage.
Does PDTC114YU-QF require external bias resistors?
No. PDTC114YU-QF integrates R1 = 10 kΩ and R2 = 47 kΩ on-die, enabling direct connection of a logic-level signal to Pin 1 (input) and load to Pin 3 (collector), with Pin 2 (emitter) grounded. No external base resistors are needed for standard digital switching operation.
Is PDTC114YU-QF pin-compatible with BC847B-Q?
No. PDTC114YU-QF uses SOT323 pinning (1 = input, 2 = GND, 3 = output), whereas BC847B-Q in SOT23 has 1 = emitter, 2 = base, 3 = collector. Physical pin mapping differs, and functional substitution requires PCB redesign-not just component replacement.
What is the typical off-state input voltage (VI(off)) for PDTC114YU-QF?
The typical VI(off) is 0.7 V, with a maximum of 0.5 V guaranteed across temperature (−40 °C to +100 °C), measured at VCE = 5 V and IC = 100 µA. This defines the upper threshold below which the device remains fully off, providing noise margin against false triggering.
