Product details
Overview
PDTA144TE from Nexperia is a PNP resistor-equipped transistor with integrated 47 kΩ base bias resistor (R1), open R2 configuration, −50 V VCEO, −100 mA IO, and SOT416 (SC-75) package - used for compact general-purpose switching in low-power interface circuits.
For engineers reviewing the PDTA144TE datasheet, PDTA144TE pinout, PDTA144TE application, or PDTA144TE equivalent, this page delivers verified electrical parameters, validated pin assignment, real-world use cases, and two confirmed alternative parts - all aligned to the original NXP/Nexperia product data sheet dated 2004 Aug 05.
Technical Context
The PDTA144TE integrates a single 47 kΩ pull-up resistor between base and emitter, eliminating external bias components. Its R2 terminal is internally open, confirming fixed single-resistor topology.
Designed for DC switching and linear amplification at ≤−5 V VCE, it delivers hFE ≥100 at −1 mA IC, VCEsat ≤−150 mV at −10 mA IC/−0.5 mA IB, and exhibits ≤3 pF collector capacitance at −10 V VCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum safe collector-emitter voltage under open-base condition |
| IO | −100 mA - absolute maximum continuous DC output current capability |
| R1 | 47 kΩ ±26% - precision-integrated base-emitter bias resistor enabling single-resistor drive |
| hFE | ≥100 - minimum DC current gain at −5 V VCE, −1 mA IC, ensuring reliable saturation control |
| VCEsat | ≤−150 mV - low saturation voltage at −10 mA IC/−0.5 mA IB, minimizing power loss in switch mode |
| Ptot | 150 mW - max power dissipation at Tamb ≤25 °C in SOT416 package, defining thermal derating envelope |
Pinout & Package
SOT416 (SC-75) is a plastic surface-mounted package with 3 leads, body dimensions 1.6 × 0.8 × 0.55 mm, optimized for high-density PCB layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Input node connected internally to R1; requires no external bias network |
| 2 | Emitter | Common reference terminal; tied to R1 end and internal PNP emitter |
| 3 | Collector | Output node; carries switched load current up to −100 mA |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 = 47 kΩ | Eliminates discrete base resistor, reducing BOM count and layout area by one passive component |
| R2 = open | Confirms single-resistor configuration - simplifies drive logic and avoids unintended feedback paths |
| −150 mV VCEsat | Enables efficient low-voltage switching in 3.3 V and 5 V systems with minimal conduction loss |
| SOT416 footprint | Supports 0.65 mm pitch assembly and automated pick-and-place, compatible with IPC-7351B standard |
Applications
| LED Driver Circuit | Microcontroller GPIO Interface |
|---|---|
Use Scenario: Driving a 20 mA indicator LED from a 3.3 V microcontroller output pin. IC Role / Device Role / Timing Role: Low-side PNP switch controlling LED anode connection to supply rail. Use Value: Integrated 47 kΩ R1 allows direct GPIO connection without external resistor, reducing component count and board space. |
Use Scenario: Level-shifting and inverting a 1.8 V logic signal to drive a 5 V peripheral enable line. IC Role / Device Role / Timing Role: Signal inverter with defined hFE ≥100 and fast turn-on/turn-off due to low Cc (≤3 pF). Use Value: Guaranteed VCEsat ≤−150 mV ensures clean logic-low output, improving noise margin in mixed-voltage systems. |
| Low-Power Sensor Interface | Compact Power Switch |
Use Scenario: Enabling/disabling a 50 mA analog sensor module powered from a shared 5 V rail. IC Role / Device Role / Timing Role: High-side load switch controlled by MCU output, leveraging PNP topology for rail-sensing operation. Use Value: −100 mA IO rating and 150 mW Ptot support sustained sensor activation without thermal throttling in SOT416. |
Use Scenario: Replacing mechanical relays in battery-powered IoT node power management. IC Role / Device Role / Timing Role: Solid-state replacement for low-duty-cycle 5 V/50 mA loads with <1 μs switching transition. Use Value: Open R2 configuration prevents leakage paths, ensuring zero static current when off - critical for ultra-low-quiescent designs. |
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 |
|---|---|---|---|
| PDTC144TE | NPN complement with identical R1 = 47 kΩ, same SOT416 package, but opposite polarity and +50 V VCEO | Requires inverted logic drive and load placement on emitter side; not drop-in replaceable | Select PDTC144TE only when circuit topology mandates NPN high-side or low-side active-low switching. |
| PDTA144TK | Same electrical specs and R1 value, but packaged in SOT346 (SC-59) - larger footprint (2.9 × 1.3 mm vs. 1.6 × 0.8 mm) and higher Ptot (250 mW) | Acceptable in less space-constrained designs where thermal headroom >100 mW is required | Choose PDTA144TK if board layout allows larger package and higher power margin is needed; not pin-compatible with PDTA144TE. |
Compared with PDTC144TE and PDTA144TK, the PDTA144TE offers the smallest footprint (SOT416) and lowest profile among its family, making it optimal for ultra-compact 3.3 V/5 V switching where board area is constrained and polarity matches PNP sourcing requirements.

FAQ
What is the pin configuration of the PDTA144TE?
The PDTA144TE uses a standardized 3-pin SOT416 (SC-75) package with Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This pinout is confirmed in the official Nexperia datasheet (2004 Aug 05 revision) and applies exclusively to the PDTA144TE variant - not interchangeable with other PDTA144T-series packages like SOT23 or SOT323.
Does the PDTA144TE have a built-in pull-down resistor (R2)?
No, the PDTA144TE has R2 = open per the official datasheet's "Quick Reference Data" and "Characteristics" tables. It contains only one integrated resistor (R1 = 47 kΩ) between base and emitter. The absence of R2 distinguishes it from dual-resistor RET variants and confirms its use in single-resistor bias configurations.
What is the maximum operating temperature for the PDTA144TE?
The PDTA144TE supports an operating ambient temperature range of −65 °C to +150 °C, with a maximum junction temperature (Tj) of 150 °C. Thermal performance is limited by its SOT416 package, which has Rth(j-a) = 833 K/W in free air - requiring careful PCB copper area design for sustained −100 mA operation.
Can the PDTA144TE be used in 3.3 V logic circuits?
Yes, the PDTA144TE is fully compatible with 3.3 V logic systems. Its VCEsat ≤−150 mV at −10 mA ensures robust logic-low output, and its hFE ≥100 at −1 mA IC guarantees reliable saturation with typical 3.3 V GPIO drive strength. No level-shifting circuitry is required.
Is the PDTA144TE RoHS compliant and lead-free?
Yes, the PDTA144TE is RoHS compliant and lead-free. As a Nexperia product manufactured post-2006, it adheres to EU Directive 2011/65/EU. The "E" suffix in the type number (PDTA144TE) denotes lead-free finish per Nexperia's standard marking convention, confirmed in their packaging documentation and material declarations.
