Product details

Overview

PDTC124XQB-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It integrates 22 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), enabling direct digital logic interfacing without external base resistors. Designed for automotive-grade switching in space-constrained PCBs, it delivers 100 mV VCE(sat) at IC = 10 mA / IB = 0.5 mA.

For engineers reviewing the PDTC124XQB-Q datasheet, PDTC124XQB-Q pinout, PDTC124XQB-Q application, or PDTC124XQB-Q equivalent, this device serves as a drop-in replacement for discrete BJT + resistor networks in low-power digital load switching, IO conditioning, and automotive body control modules where AEC-Q101 qualification, AOI compatibility, and ultra-thin 0.48 mm profile are critical.

Technical Context

This RET implements an integrated NPN silicon transistor with two monolithic thin-film resistors: R1 (22 kΩ ±30%) connected between base and input, and R2 (47 kΩ ±30%) from base to emitter. The internal topology eliminates external bias components while maintaining predictable DC current gain (hFE = 80 min at VCE = 5 V, IC = 5 mA).

Its DFN1110D-3 package features side-wettable flanks for automated optical inspection of solder joints and supports reflow profiles compliant with JEDEC J-STD-020. Thermal resistance is 298 K/W (junction-to-ambient, 70 µm copper PCB), enabling stable operation up to 150 °C junction temperature.

Key Specifications

Parameter Value and Actual Design Meaning
VCEO50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin.
IO100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs.
R122 kΩ - Input bias resistor value; sets base current for logic-level drive (e.g., 3.3 V/5 V MCU GPIO).
R2/R12.13 - Feedback resistor ratio; stabilizes operating point against β variation and temperature drift.
VCE(sat)100 mV - Low saturation voltage at IC = 10 mA / IB = 0.5 mA; minimizes power loss in on-state.
hFE80 - Minimum DC current gain at VCE = 5 V, IC = 5 mA; ensures reliable switching with defined drive.
fT230 MHz - Transition frequency of internal transistor; supports fast digital switching up to ~10 MHz.

Pinout & Package

DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin surface-mount package measuring 1.1 × 1.0 × 0.48 mm with side-wettable flanks for AOI-compatible solder joint inspection.

Pin/Terminal Circuit Role Design Meaning
1I (input)Base node connected internally to R1; accepts logic-level voltage (VI(on) = 1.1–2.0 V typical) to enable conduction.
2GND (emitter)Emitter terminal tied to system ground; serves as common return path for load current and R2.
3O (output)Collector terminal delivering switched load current; rated for 50 V and 100 mA continuous operation.

Key Features

Feature Design Value
Integrated bias networkMonolithic 22 kΩ (R1) and 47 kΩ (R2) resistors eliminate need for two external components per switch node.
AEC-Q101 qualifiedStress-tested per Automotive Electronics Council standard; suitable for under-hood and body control applications.
Side-wettable flanksPackage geometry enables automated optical inspection of solder fillets-critical for zero-defect automotive manufacturing.
Ultra-low profile0.48 mm max height allows use in ultra-thin modules (e.g., smart sensors, compact ECUs) where Z-axis space is constrained.
Low VCE(sat)100 mV saturation voltage reduces conduction losses by >50% vs. BC847-Q series at same current, improving thermal efficiency.

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
PDTC143XQB-QR1 = 4.7 kΩ, R2 = 10 kΩ; lower input resistance enables higher base current and faster switching at 3.3 V logic.Better suited for high-speed digital interfaces (e.g., UART line drivers) due to lower VI(on) threshold (1.5 V typ).Select when drive voltage is ≤3.3 V and switching speed >1 MHz is required.
BC847B-QDiscrete BJT without integrated resistors; requires external base resistor network (typically 10 kΩ + 47 kΩ).Offers higher hFE (200 min) but increases PCB area and assembly cost; not AEC-Q101 qualified.Choose only if design requires adjustable bias or higher gain, and automotive qualification is not mandatory.

Compared with PDTC143XQB-Q, the PDTC124XQB-Q provides higher input impedance for reduced drive current consumption, while BC847B-Q trades integration for flexibility and higher gain-making PDTC124XQB-Q optimal for space- and reliability-critical automotive digital switching where fixed bias suffices.

FAQ

What is the maximum ambient temperature for continuous operation?

PDTC124XQB-Q supports continuous operation from −55 °C to +150 °C ambient temperature. At 100 mA load current, thermal derating begins above 75 °C on a standard FR4 PCB with 70 µm copper; full 100 mA is guaranteed up to 85 °C with proper layout and airflow.

Can PDTC124XQB-Q replace BC847B in existing designs?

Yes-with minor layout changes. Replace the BC847B and its two external base resistors with PDTC124XQB-Q using the same collector/emitter connections; tie the input pin (Pin 1) to the original base drive signal. No resistor removal or value recalculation is needed-the internal 22 kΩ/47 kΩ network replicates typical BC847B biasing.

Is the DFN1110D-3 package compatible with standard reflow profiles?

Yes. The SOT8015 footprint complies with JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Recommended stencil thickness is 0.1 mm, and solder paste volume is optimized for side-wettable flank wetting-verified in Nexperia's reflow soldering guidelines (Fig. 37).

What is the off-state input voltage threshold (VI(off))?

VI(off) is specified as 0.5 V maximum at VCE = 5 V and IC = 100 µA. This means the device remains fully off when input voltage stays below 0.5 V, providing robust noise immunity against sub-1 V digital crosstalk or leakage in low-voltage systems.
