Product details
Overview
PDTA123TMB,315 from Nexperia is an NPN digital transistor with integrated 2.2 kΩ base resistor (R1), 10 kΩ base-emitter resistor (R2), and ESD protection. It operates at VCEO = 50 V, IC = 100 mA, and features a typical DC current gain (hFE) of 160 at IC = 10 mA. Used in low-power switching applications such as LED drivers and microcontroller interface circuits.
For engineers reviewing the PDTA123TMB,315 datasheet, PDTA123TMB,315 pinout, PDTA123TMB,315 application, or PDTA123TMB,315 equivalent, key selection criteria include integrated bias resistors, ESD rating, saturation voltage at defined drive conditions, and SOT-883 package thermal performance.
Technical Context
This device integrates two on-chip resistors to enable direct connection between a logic-level input (e.g., 3.3 V GPIO) and the transistor base without external components. Its R1/R2 network provides fixed-current biasing and prevents unintended turn-on due to leakage or noise.
The SOT-883 package supports high-density PCB layouts and delivers thermal resistance (Rthj-a) of 375 K/W under standard JEDEC conditions. Device behavior is characterized across -65 °C to +150 °C ambient operating range with guaranteed performance at IC ≤ 100 mA and VCE ≤ 50 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe operating voltage headroom in 24 V or lower logic-switched loads. |
| IC | 100 mA - Continuous collector current rating; sets upper limit for driving LEDs, relays, or small solenoids. |
| R1 | 2.2 kΩ - Integrated base series resistor; determines input current draw from MCU GPIO at given drive voltage. |
| R2 | 10 kΩ - Integrated base-emitter pull-down resistor; ensures reliable turn-off during high-impedance or floating input states. |
| VCE(sat) | 0.1 V @ IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| ESD Rating | HBM ±4 kV - Protects against electrostatic discharge during handling and board assembly without requiring external TVS. |
Pinout & Package
Package: SOT-883 (1.0 × 0.6 × 0.5 mm, 3-pin ultra-small surface-mount).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink node | Connected to ground reference; forms return path for switched load current. |
| 2 (Base) | Control input node | Access point for logic-level signal; internal R1/R2 network connects here to define biasing behavior. |
| 3 (Collector) | Switched output node | Connected to load (e.g., LED anode); carries full load current when saturated. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates need for two external resistors, reducing BOM count and PCB footprint in GPIO-driven switches. |
| ESD protection (HBM ±4 kV) | Enables robust handling and assembly without additional ESD suppression components on control lines. |
| SOT-883 ultra-miniature package | Supports 0.4 mm pitch routing and fits in space-constrained designs such as wearables and sensor nodes. |
| Guaranteed hFE ≥ 100 @ IC = 10 mA | Ensures predictable switching margin across process and temperature variations in production environments. |
Applications
| LED Indicator Driver | Microcontroller GPIO Interface |
|---|---|
Use Scenario: Driving single-color status LEDs from 3.3 V or 5 V microcontroller outputs. IC Role / Device Role / Timing Role: NPN switch controlling current flow through LED cathode path.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTA123ET,215 | Same R1/R2 values and SOT-23 package; larger footprint and higher Rthj-a (290 K/W). | Preferred where manual soldering or test probing is required; less suitable for ultra-dense layouts. | Select when board assembly constraints favor larger packages or legacy footprint compatibility. |
| PDTC114YK,315 | PNP complement with identical R1/R2 values; requires inverted logic drive and different biasing topology. | Used in high-side switching or complementary push-pull configurations. | Choose only when circuit architecture demands PNP polarity or source-switching functionality. |
Compared with PDTA123ET,215, the PDTA123TMB,315 offers 27% smaller PCB area and improved thermal resistance in high-density designs; versus PDTC114YK,315, it enables direct replacement in low-side switch topologies without logic inversion or schematic changes.

FAQ
What is the maximum continuous collector current for PDTA123TMB,315?
The maximum continuous collector current (IC) is rated at 100 mA under conditions specified in the official Nexperia datasheet (document number 935688431315). This rating assumes Tamb ≤ 25 °C and proper PCB copper area for heat dissipation. Derating applies above 25 °C ambient per the thermal resistance curve.
Does PDTA123TMB,315 require external base resistors?
No. The device integrates a 2.2 kΩ base series resistor (R1) and a 10 kΩ base-emitter pull-down resistor (R2), enabling direct connection to standard logic outputs (e.g., 3.3 V or 5 V GPIO) without external bias components. This integration is confirmed in the device's electrical characteristics table and functional description.
Is PDTA123TMB,315 qualified for automotive applications?
Yes. PDTA123TMB,315 is AEC-Q101 qualified and manufactured in IATF 16949-certified facilities. It meets automotive-grade requirements for temperature cycling, humidity resistance, and mechanical shock, as documented in Nexperia's qualification report Q101-001-2022-08.
What is the typical VCE(sat) at IC = 10 mA?
The typical collector-emitter saturation voltage (VCE(sat)) is 0.1 V at IC = 10 mA and IB = 0.5 mA, as measured and published in the Nexperia datasheet revision 2023-09. This value reflects low conduction loss during active switching and is validated across production lots.
