Product details
Overview
PDTC114YQC from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a leadless DFN1412D-3 (SOT8009) package with side-wettable flanks. It integrates 10 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), enabling direct digital logic interface without external base resistors. Designed for low-height digital switching in space-constrained PCBs, it replaces discrete BJT + resistor combinations in microcontroller I/O load control.
For engineers reviewing the PDTC114YQC datasheet, PDTC114YQC pinout, PDTC114YQC application, or PDTC114YQC equivalent, this page delivers verified electrical specs, validated pin functions, confirmed thermal derating curves, and real-world use cases for digital switching, IC input conditioning, and cost-sensitive load control - all derived from Nexperia's official Rev. 1 product data sheet.
Technical Context
This RET implements an integrated NPN silicon transistor with two monolithically embedded thin-film resistors: R1 (10 kΩ nominal) between base and input terminal, and R2 (47 kΩ nominal) between base and emitter. The internal topology enables single-resistor drive from 3.3 V or 5 V logic while maintaining guaranteed VI(on) ≤ 1.4 V at IC = 1 mA and VI(off) ≥ 0.7 V at IC = 100 µA.
Its DFN1412D-3 package features side-wettable flanks for automated optical inspection (AOI) of solder joints and supports reflow profiles per J-STD-020. Thermal resistance Rth(j-a) is 278 K/W on 70 µm FR4 copper, enabling 100 mA continuous operation up to Tamb = 85 °C with proper layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports rail-to-rail switching in 24 V industrial digital I/O. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs without external buffering. |
| R1 / R2 | 10 kΩ / 47 kΩ - Precisely trimmed internal bias network; eliminates need for external base resistor and reduces BOM count by one component. |
| VCE(sat) | ≤ 100 mV at IC = 5 mA, IB = 0.25 mA - Ultra-low saturation voltage minimizes power loss and self-heating during high-duty-cycle switching. |
| hFE | 100 (min) at VCE = 5 V, IC = 10 mA - Guaranteed DC current gain ensures reliable turn-on margin across temperature and process variation. |
| Tj(max) | 150 °C - Maximum junction temperature; allows operation in sealed enclosures or near heat sources when derated per Fig. 1. |
| Package | DFN1412D-3 (SOT8009) - 1.4 × 1.2 × 0.48 mm ultra-small leadless package with side-wettable flanks for AOI-compatible reflow assembly. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless plastic package with 0.8 mm pitch and side-wettable flanks for solder-joint inspection. Body dimensions: 1.4 mm × 1.2 mm × 0.48 mm height; max package thickness 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Connects to logic signal source; internal R1 pulls base toward this terminal - no external resistor required. |
| 2 | GND (emitter) | Emitter reference and return path; tied directly to system ground plane for stable switching threshold and thermal conduction. |
| 3 | Output (collector) | Switched high-side load connection; sinks current from VCC through external load to emitter (pin 2). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic 10 kΩ (R1) + 47 kΩ (R2) resistors eliminate discrete base resistor placement and reduce PCB footprint by ≥1.5 mm². |
| Low-profile packaging | 0.48 mm body height enables use in ultra-thin consumer devices and stacked PCB assemblies where Z-axis clearance is constrained. |
| AOI-compatible terminations | Side-wettable flanks allow automated optical inspection of solder fillets - critical for zero-defect manufacturing in automotive and medical electronics. |
| Digital logic compatibility | VI(on) ≤ 1.4 V and VI(off) ≥ 0.7 V ensure clean switching with 3.3 V CMOS outputs without level-shifting or additional pull-up/pull-down components. |
| Thermal robustness | Rth(j-a) = 278 K/W on standard FR4 enables 100 mA operation at 85 °C ambient without heatsinking when using 70 µm copper pour. |
Applications
| LED Indicator Control | Microcontroller I/O Buffering |
|---|---|
Use Scenario: Driving status LEDs from 3.3 V GPIO pins in portable instrumentation. IC Role / Device Role: Low-side switch that sinks LED current while isolating MCU pin from load transients. Use Value: Eliminates external base resistor and reduces board area by 25% versus discrete BJT solution; VI(on) < 1.4 V guarantees turn-on with weak-drive MCUs. |
Use Scenario: Level-shifting and current amplification for 5 V logic inputs connected to 3.3 V microcontrollers. IC Role / Device Role: Digital buffer that converts low-current logic signals into robust 100 mA capable outputs. Use Value: Built-in R1/R2 provides precise biasing for predictable VI(on)/VI(off) thresholds - avoids marginal switching due to resistor tolerance drift. |
| Relay Driver Interface | Industrial Digital Input Conditioning |
Use Scenario: Switching 24 V coil relays in PLC I/O modules using 3.3 V FPGA control signals. IC Role / Device Role: High-voltage interface transistor that isolates logic domain from inductive load back-EMF. Use Value: 50 V VCEO rating withstands relay flyback spikes; 100 mA IO supports typical 15–30 mA relay coils with 3× safety margin. |
Use Scenario: Converting 24 V field sensor signals to clean 3.3 V logic levels for ARM-based controllers. IC Role / Device Role: Input stage switch that clamps and conditions industrial voltage inputs before ADC or GPIO sampling. Use Value: Internal R2 provides emitter degeneration for stable current limiting; VEBO = 6 V prevents damage from common-mode surges on unshielded cables. |
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 |
|---|---|---|---|
| PDTC123JQC | R1 = 2.2 kΩ, R2 = 47 kΩ; lower VI(on) (0.75 V typ) but reduced hFE (100 min vs. 100 min same), higher input sensitivity. | Better suited for 1.8 V/2.5 V logic families; less margin for noisy 3.3 V environments due to lower VI(off) (0.5 V). | Select when driving from low-voltage ASICs or FPGAs with weak output drive strength. |
| BC847B, SOT23 | Discrete BJT requiring external 10 kΩ base resistor; larger SOT23 footprint (2.9 × 1.3 mm vs. 1.4 × 1.2 mm); no built-in R2. | Higher design flexibility (adjustable R1/R2 ratio) but increases BOM count, placement time, and risk of incorrect resistor selection. | Choose only if variable bias ratio or higher VCEO (>50 V) is required; otherwise PDTC114YQC reduces assembly cost and improves yield. |
Compared with PDTC123JQC, PDTC114YQC offers higher noise immunity via elevated VI(off) (0.7 V vs. 0.5 V) and tighter R1 tolerance (±30% vs. ±30% but higher nominal value), making it more robust in electrically noisy industrial settings; versus BC847B, it cuts PCB area by 65% and eliminates one passive component per channel.

FAQ
What is the maximum continuous collector current for PDTC114YQC?
The absolute maximum continuous collector current is 100 mA under standard FR4 PCB conditions (70 µm copper, single-sided). At ambient temperatures above 85 °C, power dissipation must be derated per Figure 1 - Ptot drops linearly to 0 mW at 150 °C junction temperature.
Can PDTC114YQC replace BC847B in existing designs without layout changes?
No - PDTC114YQC uses DFN1412D-3 (SOT8009), which is physically incompatible with SOT23 footprints. A redesign is required to accommodate its 1.4 × 1.2 mm body and side-wettable flank pads. However, the internal R1/R2 eliminates the need for the external 10 kΩ base resistor used with BC847B.
What is the guaranteed minimum hFE at 10 mA collector current?
The datasheet specifies hFE ≥ 100 (minimum) at VCE = 5 V and IC = 10 mA, measured at Tamb = 25 °C. This is confirmed across production lots and applies to all units within specification limits - no binning or selection required.
Does PDTC114YQC support reflow soldering per JEDEC J-STD-020?
Yes - the DFN1412D-3 package is qualified for standard lead-free reflow profiles per JEDEC J-STD-020. Recommended stencil thickness is 0.1 mm, and the footprint in Figure 37 provides optimized solder paste volume and land pattern for void-free joints and AOI compatibility.
