Product details
Overview
PDTA144VT from Nexperia is a PNP resistor-equipped transistor (RET) designed for general-purpose switching and interface applications. It integrates R1 = 47 kΩ and R2 = 10 kΩ bias resistors, supports −50 V VCEO, delivers −100 mA DC output current, and uses the SOT23 surface-mount package. It is commonly used in logic-level signal inversion and microcontroller I/O buffering circuits.
For engineers reviewing the PDTA144VT datasheet, PDTA144VT pinout, PDTA144VT application, or PDTA144VT equivalent, key selection considerations include its built-in resistor ratio (R2/R1 = 0.21 typ), −150 mV VCEsat at IC = −10 mA/IB = −0.5 mA, off-state input voltage range (−3.1 V to −1 V), and thermal resistance of 500 K/W in free air.
Technical Context
This device is a monolithic PNP bipolar transistor with two integrated on-die base bias resistors - R1 connected between base and input, and R2 connected between base and emitter - enabling single-resistor drive from digital logic. Its fixed R2/R1 ratio of 0.21 ensures predictable turn-on behavior without external component tuning.
The SOT23 package provides standardized 3-lead surface-mount compatibility with JEDEC TO-236AB footprint, supporting reflow soldering only. Electrical performance is specified over −65 °C to +150 °C ambient and junction temperature, with guaranteed operation up to 150 °C junction temperature under derated power conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum allowable collector-emitter voltage with base open; defines safe blocking capability in switching configurations. |
| IO (DC) | −100 mA: Continuous collector current rating; sets upper limit for load-driving capacity in steady-state operation. |
| R1 | 47 kΩ (typ): Input bias resistor value; determines base current magnitude when driven by standard CMOS/TTL logic levels. |
| R2/R1 | 0.21 (typ): Fixed internal resistor ratio; establishes stable current gain control and reduces sensitivity to β variation. |
| VCEsat | −150 mV (max at IC = −10 mA, IB = −0.5 mA): Saturation voltage drop; directly impacts power loss and voltage margin in low-side switch applications. |
| hFE | 40 (min at VCE = −5 V, IC = −5 mA): Minimum DC current gain; ensures reliable amplification or switching across process and temperature extremes. |
| Ptot | 250 mW (at Tamb ≤ 25 °C): Total power dissipation limit; requires thermal derating above 25 °C ambient per Rth(j-a) = 500 K/W. |
Pinout & Package
The PDTA144VT uses the SOT23 (TO-236AB) plastic surface-mounted package - a 3-lead, JEDEC-standard footprint measuring 2.9 × 1.3 × 1.0 mm with gull-wing leads. It is compatible with automated pick-and-place and reflow assembly processes.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive signal and routes current through R1 to base node. |
| 2 | GND (emitter) | Emitter terminal tied to system ground reference; R2 connects internally between base and this pin. |
| 3 | Output (collector) | Switched high-side output node; sinks current when device is active, suitable for driving LEDs, relays, or logic inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates need for two external resistors, reducing BOM count and PCB area in digital interface stages. |
| Reduced pick-and-place cost | Single-component replacement for discrete transistor + resistor pair, lowering placement time and placement error risk. |
| Stable switching threshold | R2/R1 = 0.21 ensures consistent VI(on)/VI(off) behavior across temperature and process, improving noise immunity. |
| Logic-compatible input | VI(on) ≤ −3.8 V (typ) and VI(off) ≥ −3.1 V (typ) enable direct interfacing with 3.3 V and 5 V CMOS outputs. |
Applications
| Microcontroller I/O Buffering | LED Driver Interface |
|---|---|
|
Use Scenario: Driving 5 V LED indicators from 3.3 V GPIO pins with level-shifting and current limiting. IC Role / Device Role / Timing Role: Acts as a PNP-based high-side switch that inverts logic polarity while sourcing current to the LED anode.

| Logic-Level Signal Inversion | Power Rail Enable Switch |
|
Use Scenario: Converting active-high enable signals to active-low control for legacy peripherals or PMICs. IC Role / Device Role / Timing Role: Provides fast, rail-to-rail inversion with minimal propagation delay due to optimized internal resistor values. Use Value: VI(on) and VI(off) thresholds tightly bracket standard logic levels, ensuring clean transitions without floating input states. |
Use Scenario: Enabling/disabling auxiliary 3.3 V or 5 V rails in industrial controllers using microcontroller GPIO. IC Role / Device Role / Timing Role: Serves as a low-cost, low-power enable switch in power sequencing networks, replacing discrete MOSFET solutions. Use Value: −50 V VCEO rating provides ample margin against supply transients, and 250 mW Ptot allows continuous operation at full rated current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC144VT | NPN complement with identical R1/R2 values and SOT23 package; requires inverted logic drive and low-side switching topology. | Suitable for low-side loads (e.g., N-channel MOSFET gate drive) rather than high-side sourcing like PDTA144VT. | Select when circuit architecture favors sinking current and logic polarity matches NPN drive requirements. |
| EMZ7T2R | PNP RET with R1 = 47 kΩ, R2 = 10 kΩ, but in SC-70 (SOT323) package; slightly higher Rth(j-a) = 625 K/W and lower Ptot = 200 mW. | Offers same electrical behavior but reduced power handling; best for space-constrained, low-duty-cycle applications. | Choose only if PCB layout mandates SC-70 footprint and thermal load remains below 150 mW average. |
Compared with PDTC144VT and EMZ7T2R, PDTA144VT uniquely combines PNP high-side switching capability, SOT23 mechanical robustness, and 250 mW thermal budget - making it optimal for general-purpose logic interface and rail-enable functions where polarity and package compatibility are fixed constraints.

FAQ
What is the maximum operating temperature for PDTA144VT?
The PDTA144VT has a maximum junction temperature (Tj) of 150 °C and a storage temperature range of −65 °C to +150 °C. Its thermal resistance from junction to ambient is 500 K/W in free air, so continuous operation at full −100 mA load requires ambient temperatures below 87.5 °C to stay within the 250 mW power limit.
Can PDTA144VT replace a discrete PNP transistor plus two resistors?
Yes - PDTA144VT replaces a standard PNP transistor (e.g., BC807) plus 47 kΩ and 10 kΩ base bias resistors. Its internal R1–R2 network matches typical digital interface requirements, eliminating layout complexity, reducing component count by three, and improving assembly yield in high-volume production.
Is PDTA144VT RoHS compliant and halogen-free?
Yes - PDTA144VT meets RoHS Directive 2011/65/EU and is halogen-free per Nexperia's standard product compliance policy. The device carries the "HF" marking designation and conforms to JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/85% RH.
Does PDTA144VT support through-hole mounting?
No - PDTA144VT is exclusively offered in the SOT23 surface-mount package. For through-hole alternatives, consider the PDTA144VS variant in SOT54 (TO-92) package, which shares identical electrical characteristics but uses leaded through-hole construction.
