Product details
Overview
PDTA144WT from Nexperia is a PNP resistor-equipped transistor (RET) with integrated bias resistors R1 = 47 kΩ and R2 = 22 kΩ, designed for compact switching applications in space-constrained PCB layouts. It features VCEO = −50 V, IO = −100 mA, VCEsat ≤ −150 mV at IC = −10 mA/IB = −0.5 mA, and is housed in the SOT23 surface-mount package. It is commonly used in level-shifting interface circuits for microcontroller GPIOs driving LEDs or small relays.
For engineers reviewing the PDTA144WT datasheet, PDTA144WT pinout, PDTA144WT application, or PDTA144WT equivalent, key selection considerations include its fixed resistor ratio (R2/R1 ≈ 0.47), guaranteed Vi(off) (−1.7 to −1.2 V), thermal resistance of 500 K/W, and compatibility with reflow-only soldering per JEDEC J-STD-020.
Technical Context
This device integrates two precision thin-film resistors (R1 = 47 kΩ, R2 = 22 kΩ) directly into a PNP bipolar die to eliminate external base bias components. Its internal resistor network enables direct logic-level drive from 3.3 V or 5 V CMOS outputs without external pull-up/down networks.
The transistor operates with guaranteed DC current gain (hFE) ≥ 60 at VCE = −5 V and IC = −5 mA, and exhibits low leakage: ICEO ≤ −1 μA at VCE = −30 V and IB = 0 A. Junction temperature is rated up to 150 °C, supporting industrial ambient operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter reverse voltage before breakdown |
| IO | −100 mA - Continuous DC output current capability under thermal limits |
| R1 | 47 kΩ ±28% - Integrated base pull-up resistor enabling single-wire logic interface |
| R2 | 22 kΩ ±28% - Integrated base-emitter feedback resistor stabilizing bias point |
| VCEsat | ≤ −150 mV - Low saturation voltage ensures minimal power loss in switching mode |
| hFE | ≥ 60 - Minimum DC current gain supports reliable switching with low drive current |
| Tj | 150 °C - Maximum junction temperature allows operation in high-ambient environments |
Pinout & Package

| Guaranteed Vi(off) | −1.7 to −1.2 V ensures reliable turn-off with 0 V logic low, preventing unintended conduction |
| Reflow-only assembly compliance | Qualified per JEDEC J-STD-020, eliminating wave soldering process risk for SMT lines |
| Low thermal resistance | Rth(j-a) = 500 K/W enables 250 mW dissipation at Tamb ≤ 25 °C without heatsinking |
Applications
| LED Driver Interface | Microcontroller GPIO Expander |
|---|---|

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 |
|---|---|---|---|
| PDTC144ET,215 | NPN complement; same R1/R2 values but opposite polarity; VCEO = +50 V, IO = +100 mA | Requires high-side switching topology instead of low-side; not interchangeable without circuit redesign | Select when driving loads referenced to ground with positive logic control. |
| EMH11T2R | PNP RET with R1 = 100 kΩ, R2 = 100 kΩ; higher input impedance; VCEO = −50 V, IO = −100 mA | Higher Vi(on) (−3.5 to −2.0 V) reduces noise immunity; less suitable for 3.3 V logic interfaces | Prefer for 5 V systems where higher input threshold improves EMI rejection. |
Compared with PDTC144ET,215 and EMH11T2R, PDTA144WT offers optimal balance of low Vi(on) (−4 to −2.7 V), tight resistor tolerance (±28%), and SOT23 footprint-making it ideal for 3.3 V microcontroller interface applications requiring minimal board area and guaranteed turn-on behavior.

FAQ
Is PDTA144WT compatible with lead-free reflow soldering processes?
Yes, PDTA144WT is qualified for lead-free reflow soldering per JEDEC J-STD-020. Its SOT23 package supports peak temperatures up to 260 °C for 30 seconds. Wave soldering is explicitly not recommended due to thermal stress risks on the internal resistor elements and die attach.
What is the maximum continuous current this device can switch reliably?
The PDTA144WT supports −100 mA DC output current (IO) at Tamb ≤ 25 °C with proper PCB copper pour. At higher ambient temperatures, derating applies: at 70 °C ambient, maximum usable current drops to approximately −65 mA to maintain Tj ≤ 150 °C given its Rth(j-a) = 500 K/W.
Can PDTA144WT replace a standard PNP transistor like BC807 in existing designs?
No-PDTA144WT is not a drop-in replacement for discrete transistors such as BC807. Its pin 1 connects to the internal R1–R2 node, not the bare base. Substituting it requires removing external base resistors and verifying logic-level compatibility, as its Vi(on) and Vi(off) thresholds differ significantly from bare-transistor biasing requirements.
Does this part have AEC-Q101 qualification for automotive use?
No, PDTA144WT is not AEC-Q101 qualified. While Nexperia offers AEC-Q101 variants in the same RET family (e.g., PDTA144WQ series), the PDTA144WT variant is intended for industrial and consumer applications. For automotive-grade reliability, consult Nexperia's qualified portfolio and verify part number suffixes indicating AEC compliance.
