Product details
Overview
PDTC123TMB from Nexperia is an NPN resistor-equipped transistor (RET) in a leadless DFN1006B-3 (SOT883B) package, designed for digital switching in space-constrained PCBs. It integrates a 2.2 kΩ input bias resistor (R1), supports 100 mA output current, withstands 50 V VCEO, and is AEC-Q101 qualified for automotive use.
For engineers reviewing the PDTC123TMB datasheet, PDTC123TMB pinout, PDTC123TMB application, or PDTC123TMB equivalent, this device serves as a drop-in replacement for discrete base-resistor transistor configurations in low-power logic interfacing, peripheral control, and mobile I/O buffering where board area and assembly cost are critical.
Technical Context
This RET integrates a monolithic NPN transistor with a single 2.2 kΩ base-input resistor (R1); R2 is open, confirming single-resistor configuration. Its 0.37 mm profile and 1.0 × 0.6 mm footprint enable placement on ultra-dense HDI boards.
With fT = 230 MHz and hFE ≥ 30 at IC = 20 mA, it delivers fast switching performance while maintaining low VCEsat ≤ 150 mV at IC = 10 mA / IB = 0.5 mA - suitable for driving CMOS/TTL inputs and LED indicators without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports rail-to-rail switching up to 5 V logic systems with margin for transient spikes. |
| IO | 100 mA - sufficient to drive multiple logic inputs, small LEDs, or low-power relays directly. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ range) - sets base current for predictable saturation with 3.3 V/5 V microcontroller outputs. |
| VCEsat | ≤ 150 mV at IC = 10 mA - minimizes power loss and self-heating in always-on or pulsed control nodes. |
| fT | 230 MHz - enables clean edge response in signal routing and high-speed enable/disable functions. |
| Package | DFN1006B-3 (SOT883B), 1.0 × 0.6 × 0.37 mm - compatible with 0201-class pick-and-place and reflow processes. |
| AEC-Q101 | Qualified - validated for automotive under-hood and infotainment applications per stress test requirements. |
Pinout & Package
DFN1006B-3 (SOT883B) is a 3-terminal, leadless, bottom-terminated plastic package with 0.37 mm height, optimized for automated assembly and thermal conduction through the exposed emitter pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive (e.g., MCU GPIO) without external resistor. |
| 2 | GND (emitter) | Common reference and thermal path; soldered directly to PCB ground plane for low-inductance return and heat dissipation. |
| 3 | Output (collector) | Switched output node; connects to load (e.g., LED anode, IC input, pull-up network) with minimal trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | Eliminates need for external base resistor, reducing BOM count and layout area by one passive component. |
| Ultra-small footprint | 1.0 × 0.6 mm body size enables placement in tight spaces such as smartphone camera modules or wearable sensor hubs. |
| Low profile (0.37 mm) | Permits stacking under shields or integration into slim-profile enclosures without mechanical interference. |
| AEC-Q101 qualification | Validated for temperature cycling, HTRB, and ESD per automotive reliability standards - no additional qualification needed for Tier-1 designs. |
| 100 mA continuous output | Supports direct driving of multiple 74LVC inputs or dual-color indicator LEDs without buffer stages. |
Applications
| Mobile Peripheral Control | Automotive Body Electronics |
|---|---|
|
Use Scenario: Enabling/disabling sensors, LEDs, or audio amplifiers in smartphones and wearables using 1.8 V or 3.3 V GPIOs. IC Role / Device Role / Timing Role: Digital switch controlling power or signal path to low-current peripherals. Use Value: Reduces PCB area by eliminating discrete base resistors and simplifies firmware logic by enabling direct GPIO control without current-limiting calculations. |
Use Scenario: Driving door lock actuators, mirror position feedback inputs, or HVAC status indicators in automotive cabin modules. IC Role / Device Role / Timing Role: Level-shifting and isolation interface between microcontroller I/O and 5 V/12 V subsystems. Use Value: AEC-Q101 qualification ensures long-term reliability in temperature-cycled environments, avoiding field failures due to bias resistor drift or solder fatigue. |
| Industrial I/O Expansion | Consumer Appliance Logic Interface |
|
Use Scenario: Adding isolated digital outputs to PLC I/O cards or smart sensor nodes with limited board real estate. IC Role / Device Role / Timing Role: Low-side switch translating MCU logic signals into robust 5 V/24 V-compatible control lines. Use Value: 100 mA rating allows parallel connection of up to four TTL loads per channel, reducing channel count and system cost. |
Use Scenario: Controlling display backlight segments, buzzer drivers, or button illumination in washing machines or air conditioners. IC Role / Device Role / Timing Role: General-purpose digital output stage replacing BC847 + resistor combinations. Use Value: Simplified procurement (single SKU vs. transistor + resistor) and guaranteed resistor tolerance (±30%) improve production yield and consistency. |
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 |
|---|---|---|---|
| PDTC114TMB | R1 = 10 kΩ (vs. 2.2 kΩ), lower base current - suited for higher-VCC or lower-drive GPIOs. | Requires higher input voltage (≥4.5 V) to achieve same IC; less suitable for 1.8 V logic. | Select when driving from 5 V microcontrollers or when lower base current reduces MCU loading. |
| PDTA123TMB | PNP complement with identical R1 value and package - not functionally interchangeable without circuit redesign. | Used for high-side switching or inverted logic paths; requires complementary bias network. | Choose only for PNP-specific topologies (e.g., active-low enable, high-side LED anode control). |
Compared with PDTC114TMB, PDTC123TMB delivers stronger base drive at low voltages, enabling reliable saturation with 3.3 V MCUs; versus PDTA123TMB, it provides non-inverting logic control essential for direct GPIO interfacing without level-shifting.

FAQ
What is the maximum continuous collector current for PDTC123TMB?
The maximum continuous collector current is 100 mA, verified under standard FR4 PCB conditions with single-sided copper. Derating begins above 25 °C ambient per the 500 K/W junction-to-ambient thermal resistance curve; at 85 °C ambient, usable current drops to approximately 65 mA.
Can PDTC123TMB be used with 1.8 V logic inputs?
Yes - with R1 = 2.2 kΩ, a 1.8 V input delivers ~0.82 mA base current, sufficient to saturate the transistor at IC ≤ 20 mA (hFE ≥ 30). For higher loads, verify VCEsat remains ≤ 200 mV using the typical curves in Figure 5 of the datasheet.
Is PDTC123TMB pin-compatible with SOT-23 or SC-70 packages?
No - PDTC123TMB uses the DFN1006B-3 (SOT883B) package, which has three bottom-terminated pads in a 1.0 × 0.6 mm outline. It is not mechanically or solder-reflow compatible with SOT-23 (2.9 × 1.3 mm) or SC-70 (2.0 × 1.25 mm) packages due to footprint and thermal pad differences.
Does PDTC123TMB include ESD protection on its pins?
No - the datasheet does not specify integrated ESD protection diodes. External TVS or series resistors are recommended when connecting to exposed interfaces (e.g., buttons, connectors) in handheld or automotive environments per IEC 61000-4-2 Level 2+ requirements.
