Product details
Overview
PDTC115TMB from Nexperia is an NPN resistor-equipped transistor (RET) in a leadless DFN1006B-3 (SOT883B) package, designed for digital switching in space-constrained applications. It integrates a 100 kΩ input bias resistor (R1), supports 100 mA output current, and features 50 V VCEO, AEC-Q101 qualification, and 0.37 mm package height - used in mobile peripheral drivers and IC input control circuits.
For engineers reviewing the PDTC115TMB datasheet, PDTC115TMB pinout, PDTC115TMB application, or PDTC115TMB equivalent, key selection criteria include built-in R1 value (70–130 kΩ), ultra-small 1.0 × 0.6 mm footprint, GND-emitter terminal configuration, and automotive-grade reliability for low-power digital interface design.
Technical Context
This NPN RET replaces discrete transistor + base-resistor combinations by embedding R1 (100 kΩ typ.) between base and input pin, with emitter tied directly to ground. Its internal structure eliminates external bias components while maintaining standard NPN switching behavior under IC-level logic drive conditions.
Designed for direct interfacing with 1.8 V to 5 V CMOS/TTL outputs, it delivers guaranteed hFE ≥100 at IC = 1 mA and VCE = 5 V, with VCE(sat) ≤150 mV at IC = 5 mA / IB = 0.25 mA - enabling robust low-voltage switching without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum safe collector-emitter voltage during switching, compatible with 24 V industrial logic rails and 5 V microcontroller interfaces. |
| IO | 100 mA - continuous output current capability sufficient for driving LEDs, small relays, or logic inputs without external current amplification. |
| R1 | 100 kΩ (70–130 kΩ) - integrated base-input resistor enables direct connection to GPIO pins; eliminates need for external bias network. |
| Package | DFN1006B-3 (SOT883B), 1.0 × 0.6 × 0.37 mm - ultra-compact leadless package optimized for high-density PCB layouts in mobile and wearable devices. |
| AEC-Q101 | Qualified - certified for automotive applications including body electronics and infotainment subsystems requiring extended temperature and reliability validation. |
| VCE(sat) | ≤150 mV at IC = 5 mA / IB = 0.25 mA - ensures minimal power loss and heat generation in always-on or pulsed digital control paths. |
| fT | 230 MHz - transition frequency supports fast edge rates in signal routing and timing-critical digital enable/disable functions. |
Pinout & Package
DFN1006B-3 (SOT883B) is a 3-terminal, leadless plastic surface-mount package with 0.37 mm profile, 0.22 mm pad pitch, and exposed thermal pad not connected internally. Dimensions: 1.0 mm × 0.6 mm × 0.37 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected to internal R1; accepts logic-level drive directly from MCU GPIO or buffer output. |
| 2 | GND (emitter) | Emitter tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched node for load connection; sinks current when active, compatible with open-collector logic configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistor network | Single 100 kΩ R1 eliminates two external resistors and reduces BOM count by one component per switch channel. |
| Ultra-small footprint | 1.0 × 0.6 mm area saves >70% board space versus SOT23-3, critical for multi-channel sensor modules and compact wearables. |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (−40 °C to +150 °C) and mechanical stress, supporting under-hood and dashboard applications. |
| Low saturation voltage | VCE(sat) ≤150 mV ensures <150 µW dissipation at 1 mA load, minimizing self-heating in thermally isolated PCB regions. |
| High DC current gain | hFE ≥100 at IC = 1 mA enables reliable turn-on with weak drive sources such as I²C bus buffers or low-current logic gates. |
Applications
| Mobile Peripheral Driver | IC Input Control |
|---|---|
Use Scenario: Driving LED indicators, vibration motors, or SIM card detection switches in smartphones and tablets. IC Role / Device Role: NPN switch sinking current from VCC-referenced loads to GND under GPIO control. Use Value: Eliminates discrete resistor placement and reduces assembly steps in high-volume automated SMT lines. |
Use Scenario: Enabling/disabling enable pins on PMICs, ADCs, or level shifters using microcontroller outputs. IC Role / Device Role: Logic-level translator and current amplifier ensuring clean, noise-immune activation signals. Use Value: Guarantees stable hFE ≥100 across −40 °C to +85 °C, preventing false disable events in battery-powered systems. |
| Automotive Body Electronics | Digital Signal Routing |
Use Scenario: Controlling door lock actuators, mirror position sensors, or HVAC status LEDs in passenger compartments. IC Role / Device Role: AEC-Q101-qualified digital switch interfacing 3.3 V/5 V MCU outputs with 12 V vehicle loads via external pull-up. Use Value: Meets automotive transient immunity requirements (ISO 7637-2) due to robust VCEO = 50 V rating and low parasitic capacitance (2.5 pF). |
Use Scenario: Isolating and routing reset, interrupt, or chip-select signals between mixed-voltage SoC domains. IC Role / Device Role: Level-adaptive buffer providing galvanic separation and current gain without directionality constraints. Use Value: fT = 230 MHz supports clean propagation of 10–20 MHz control signals with <1 ns rise-time degradation. |
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 |
|---|---|---|---|
| PDTC124TMB | R1 = 22 kΩ (typ.), higher base drive sensitivity but lower input impedance. | Better suited for 1.8 V logic interfaces where lower R1 ensures adequate IB at reduced VIN. | Select when driving from sub-2.5 V MCUs or when faster turn-on is required despite higher standby current. |
| PDTA115TMB | PNP complement with identical R1 = 100 kΩ, same package, but sourcing (not sinking) output configuration. | Used where load must be connected to GND and switched on the high side (e.g., supply rail enable). | Choose for complementary high-side control in dual-rail power management or bidirectional signal conditioning circuits. |
Compared with PDTC124TMB, PDTC115TMB provides higher input impedance for reduced GPIO loading at 3.3 V/5 V; compared with PDTA115TMB, it offers sink-switching topology essential for grounded-load configurations in most digital interface designs.

FAQ
What is the function of Pin 2 (GND) in PDTC115TMB?
Pin 2 is the emitter terminal, internally connected to system ground and serving as the common reference for both input (Pin 1) and output (Pin 3) paths. It is not a separate ground plane connection but the transistor's emitter node - required to be tied directly to PCB ground for proper biasing and current sinking operation.
Can PDTC115TMB replace a standard 2N3904 with external base resistors?
Yes - PDTC115TMB replaces a 2N3904 plus two external resistors (RB and RE) in digital switch applications. Its integrated 100 kΩ R1 provides equivalent base biasing for 3.3 V/5 V logic drive, eliminating layout complexity and reducing solder joints while maintaining VCE(sat) ≤150 mV performance.
Is thermal derating required for continuous 100 mA operation?
Yes - at ambient temperatures above 25 °C, power dissipation must be limited per the derating curve: Ptot drops linearly from 250 mW at 25 °C to 0 mW at 150 °C. At 100 mA and VCE(sat) = 150 mV, power is 15 mW, allowing full-rated current up to ~125 °C ambient on standard FR4 PCBs.
Does PDTC115TMB support PWM switching at 10 kHz?
Yes - with fT = 230 MHz and low CC = 2.5 pF, PDTC115TMB supports clean 10 kHz PWM switching with negligible delay or distortion. Turn-on/off times are typically <100 ns, enabling precise duty-cycle control for LED dimming or motor enable signals.
