Product details
Overview
PDTC124XMB from Nexperia is an NPN resistor-equipped transistor (RET) in a leadless DFN1006B-3 (SOT883B) package, designed as a single-chip digital switch with integrated 22 kΩ input bias resistor (R1) and 47 kΩ base-emitter resistor (R2). It delivers 100 mA output current, supports 50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive use in low-power peripheral driver circuits.
For engineers reviewing the PDTC124XMB datasheet, PDTC124XMB pinout, PDTC124XMB application, or PDTC124XMB equivalent, this device serves as a space-optimized, pick-and-place–friendly replacement for discrete BJT + resistor combinations in digital logic interface and IC input control applications where board area, assembly cost, and thermal reliability are critical.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors - R1 connected between input and base, R2 between base and emitter - enabling direct TTL/CMOS-level drive without external bias components. The internal resistor ratio (R2/R1 = 2.1 typ.) ensures stable saturation under varying temperature and supply conditions.
Its ultra-thin 0.37 mm profile and 1.0 × 0.6 mm footprint support high-density routing in portable and automotive modules. Thermal resistance (Rth(j-a) = 500 K/W) and 150 °C max junction temperature allow operation in thermally constrained environments when mounted on standard FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Enables safe switching of 3.3 V and 5 V logic-controlled loads with margin against transients. |
| IO | 100 mA - Sufficient to drive LEDs, small relays, or logic inputs without external amplification. |
| R1 | 22 kΩ ±29% - Sets input current limit and defines logic-high threshold for direct microcontroller GPIO interfacing. |
| R2/R1 Ratio | 2.1 typ. - Ensures robust saturation by providing adequate base current even with hFE variation across temperature. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Supports continuous operation in ambient temperatures up to 85 °C with derating. |
| fT | 230 MHz - Confirms suitability for fast-switching digital signals up to ~10–20 MHz edge rates. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22. |
Pinout & Package
DFN1006B-3 (SOT883B) is a 3-terminal, leadless plastic package measuring 1.0 × 0.6 × 0.37 mm with exposed pad not electrically connected. Its ultra-small footprint and low height enable integration into space-constrained mobile and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base via R1) | Accepts logic-level signal; current flows through R1 to bias the internal NPN transistor. |
| 2 | GND (emitter) | Common reference node; connects directly to system ground and provides return path for load current. |
| 3 | Output (collector) | Switches load to ground; rated for 100 mA DC and 50 V VCEO; requires external pull-up for active-low configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates need for two external resistors, reducing BOM count and PCB real estate by ≥3 components per channel. |
| Leadless DFN1006B-3 package | Reduces mounting area by >70% vs. SOT23 while maintaining solder joint reliability via optimized land pattern. |
| 100 mA IO capability | Supports direct driving of status LEDs, optocoupler inputs, and low-power logic buffers without buffer stages. |
| AEC-Q101 qualification | Validates performance across -40 °C to +125 °C ambient with lifetime testing for automotive infotainment and body electronics. |
| Low VCE(sat) | 150 mV max at IC = 10 mA / IB = 0.5 mA - Minimizes power loss and self-heating in battery-powered systems. |
Applications
| Automotive Interior Lighting Control | Portable Device LED Indicators |
|---|---|
Use Scenario: Driving individual status LEDs in door modules, HVAC panels, or center consoles. IC Role / Device Role / Timing Role: Low-side switch controlled by MCU GPIO to sink LED current. Use Value: Eliminates discrete resistor + transistor layout, reduces component count per LED channel, and enables 0.6 mm × 1.0 mm placement in tight bezel areas. |
Use Scenario: Enabling/disabling notification LEDs in wearables and Bluetooth earbuds. IC Role / Device Role / Timing Role: Digital on/off switch interfaced directly with 1.8 V or 3.3 V SoC outputs. Use Value: Ultra-low package height (0.37 mm) avoids interference with battery or flex cable stacking; 100 nA ICBO minimizes standby leakage. |
| Industrial Sensor Interface Logic | Consumer Appliance Button Feedback |
Use Scenario: Level-shifting and buffering digital signals from Hall-effect or reed switches to microcontroller inputs. IC Role / Device Role / Timing Role: Signal conditioner that converts open-collector sensor outputs to clean CMOS-compatible logic levels. Use Value: Built-in R2 stabilizes base voltage during noise events; 2.5 pF CC ensures minimal signal distortion at 100 kHz switching. |
Use Scenario: Providing tactile LED feedback for membrane keypad presses in kitchen appliances. IC Role / Device Role / Timing Role: Low-current load switch activated by 3.3 V microcontroller output pins. Use Value: VI(on) = 1.1 V typ. allows reliable turn-on from weak-drive GPIOs; AEC-Q101 qualification ensures long-term reliability in high-humidity 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 |
|---|---|---|---|
| PDTC143XMB | R1 = 47 kΩ, R2 = 100 kΩ → higher input impedance, lower IB, reduced switching speed | Better suited for ultra-low-power wake-up circuits where input current < 10 µA is required | Select when driving high-impedance MCU inputs or extending battery life in always-on sensors |
| EMH11T2R | Same DFN1006B-3 package but PNP RET with R1 = 47 kΩ, R2 = 47 kΩ; complementary topology | Used for high-side switching or inverted logic configurations where sourcing current is needed | Choose for rail-to-rail level translation or when matching PDTA124XMB in dual-polarity driver designs |
Compared with PDTC124XMB, PDTC143XMB offers higher input resistance for lower drive current but slower response, while EMH11T2R provides PNP complementarity in identical footprint - both require circuit-level validation for bias point and timing compatibility.

FAQ
What is the maximum continuous collector current for PDTC124XMB?
The absolute maximum continuous collector current (IO) is 100 mA at Tamb ≤ 25 °C, with derating to zero at 150 °C ambient per the power derating curve. At 85 °C ambient, usable current is approximately 65 mA assuming standard FR4 PCB mounting with single-sided copper.
Can PDTC124XMB be used with 1.8 V logic inputs?
Yes - its VI(on) is specified at 1.1 V (typ.) and 2.0 V (max) at IC = 2 mA, ensuring reliable turn-on with 1.8 V CMOS outputs. However, ensure the source can deliver ≥50 µA to overcome R1; most modern MCUs meet this requirement.
Is there an exposed thermal pad on the DFN1006B-3 package?
No - the DFN1006B-3 (SOT883B) package has no electrically or thermally connected exposed pad. Thermal dissipation relies solely on the three solder lands and PCB copper area; recommended footprint includes 0.3 mm solder paste deposits on each land per Nexperia's reflow guidelines.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 2.1 (typ.) sets the internal base bias divider, ensuring sufficient base current for saturation across hFE variation and temperature drift. A higher ratio improves noise immunity but increases input capacitance; this value balances speed, gain stability, and robustness in automotive environments.
