Product details
Overview
PDTC123YTR from Nexperia is an NPN resistor-equipped transistor (RET) in SOT23 package, integrating R1 = 2.2 kΩ and R2 = 10 kΩ bias resistors. It delivers 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive-grade switching in interface circuits with simplified base drive.
For engineers reviewing the PDTC123YTR datasheet, PDTC123YTR pinout, PDTC123YTR application, or PDTC123YTR equivalent, this page provides verified pin functions, real-world use scenarios, thermal derating data, and validated alternatives for circuit design and BOM optimization.
Technical Context
This RET integrates two precision bias resistors to eliminate external base components, enabling direct logic-level drive with defined VI(on)/VI(off) thresholds (1.15 V typ / 0.75 V typ). Its internal R2/R1 ratio of 4.5 ensures stable saturation under varying temperature conditions.
The device operates as a single-stage digital switch with fixed current gain (hFE ≥ 35 at IC = 5 mA), low VCEsat (≤ 150 mV), and robust isolation (ICBO ≤ 100 nA), making it suitable for level translation and load control where discrete bias networks would increase footprint and assembly cost.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial supply rails. |
| IO | 100 mA - Continuous output current rating; supports driving LEDs, small relays, or logic inputs without external current limiting. |
| R1 | 2.2 kΩ ±30% - Input bias resistor value; sets base current for predictable turn-on with standard CMOS/TTL logic outputs. |
| R2/R1 | 4.5 - Fixed internal feedback ratio; stabilizes operating point against β variation and temperature drift. |
| VCEsat | ≤150 mV at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching applications. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors; supports under-hood and body-control module deployment. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm); 3-terminal layout with 1.9 mm pitch; designed for reflow and wave soldering per IPC-7351B standard footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Connected internally to R1; accepts logic-level drive directly-no external series resistor required. |
| 2 (GND) | Ground (emitter node) | Emitter tied to system ground; serves as common reference for input and output paths. |
| 3 (O) | Output (collector node) | Switched high-side output; connects to load (e.g., LED anode or relay coil) referenced to positive rail. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates need for two external resistors, reducing PCB area by ~1.5 mm² and eliminating placement errors. |
| Logic-compatible input threshold | VI(on) = 1.15 V typ at IC = 20 mA enables direct drive from 1.8 V/3.3 V/5 V microcontrollers without level shifters. |
| Thermal robustness | Rth(j-a) = 500 K/W on FR4 PCB allows 250 mW operation at Tamb ≤ 25 °C; derates linearly above 25 °C per Fig. 1. |
| Automotive qualification | AEC-Q101 compliance confirms reliability across -40 °C to +125 °C ambient, including temperature cycling and HAST. |
Applications
| Automotive Body Control | Industrial Sensor Interface |
|---|---|
Use Scenario: Driving door lock actuators and interior lighting loads in 12 V vehicle systems. IC Role / Device Role / Timing Role: NPN switch controlling grounded loads via microcontroller GPIO. Use Value: Eliminates external base resistor network, reducing BOM count and improving production yield in high-volume ECUs. |
Use Scenario: Level-shifting analog sensor outputs (e.g., thermistor divider) to 3.3 V ADC inputs. IC Role / Device Role / Timing Role: Digital buffer isolating noisy 5 V sensor domain from sensitive low-voltage measurement circuitry. Use Value: Internal R2 feedback prevents latch-up during transient overvoltage events common in industrial environments. |
| Consumer Appliance Control | IoT Peripheral Driver |
Use Scenario: Switching solenoid valves and indicator LEDs in smart washing machines and HVAC controls. IC Role / Device Role / Timing Role: General-purpose load switch activated by MCU PWM or digital output. Use Value: Guaranteed VCEsat ≤ 150 mV ensures minimal self-heating during continuous duty cycles up to 100%. |
Use Scenario: Enabling/disabling BLE module power rails and status LEDs in battery-powered edge nodes. IC Role / Device Role / Timing Role: Low-power enable switch with sub-µA leakage (ICEO ≤ 5 µA at Tj = 150 °C). Use Value: VI(off) ≤ 0.75 V ensures reliable cutoff even with weak pull-downs or floating MCU pins during sleep modes. |
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 |
|---|---|---|---|
| PDTC143ZTR | R1 = 4.7 kΩ, R2 = 47 kΩ; higher input impedance; lower IO rating (100 mA same, but hFE min = 80 at IC = 10 mA) | Better suited for high-impedance microcontroller outputs (e.g., ultra-low-power MCUs with weak drive strength) | Select when base drive current must be < 1 mA at 3.3 V; not drop-in due to different R1/R2 ratio and gain profile. |
| MMBT3904LT1G | Discrete NPN BJT with no built-in resistors; requires external RB; higher VCEO (40 V), same SOT23 package | Offers full design flexibility for custom biasing but increases component count and layout complexity | Choose only if precise gain control or non-standard switching thresholds are required; adds two passive components and tuning effort. |
Compared with PDTC123YTR, PDTC143ZTR offers higher input impedance for weak-drive sources but less margin in saturation voltage at high current, while MMBT3904LT1G provides full bias customization at the cost of increased design time and BOM size.

FAQ
What is the maximum continuous collector current for PDTC123YTR?
The maximum continuous output current (IO) is 100 mA at Tamb ≤ 25 °C. Derating applies above 25 °C per the power derating curve in Figure 1: Ptot decreases linearly to zero at 150 °C junction temperature, corresponding to ~150 mW at 75 °C ambient.
Can PDTC123YTR replace a standard BJT like BC847 in existing designs?
PDTC123YTR is not a direct replacement for BC847 due to its integrated bias network. It replaces both the BJT and its two base resistors. To retrofit, remove external RB and RB2, connect microcontroller GPIO directly to Pin 1 (I), emitter to ground (Pin 2), and load between VCC and Pin 3 (O).
Is PDTC123YTR suitable for PWM-driven loads?
Yes-its 150 mV VCEsat and 100 mA IO rating support PWM frequencies up to 100 kHz with minimal switching loss. Thermal resistance (500 K/W) and junction temperature limit (150 °C) allow sustained 50% duty cycle at 100 mA with adequate PCB copper area.
What does the marking code '%AL' indicate on PDTC123YTR units?
The marking code '%AL' consists of a site-specific placeholder ('%') followed by 'AL', which identifies the device as PDTC123YT. The '%' character is replaced by a letter denoting the manufacturing location (e.g., 'A' for Manchester, UK), per Table 4 in the official Nexperia datasheet.
