NXP Semiconductors PDTA144VE,115

Overview

PDTA144VE from Nexperia is a PNP resistor-equipped transistor (RET) in SOT416 (SC-75) package, featuring integrated bias resistors R1 = 47 kΩ and R2/R1 = 0.21, −50 V V_CEO, −100 mA I_O, and −150 mV V_CEsat at I_C = −10 mA/I_B = −0.5 mA. It serves as a compact, single-device replacement for base-resistor + PNP BJT combinations in low-power switching circuits such as LED drivers and logic-level translators.

For engineers reviewing the PDTA144VE datasheet, PDTA144VE pinout, PDTA144VE application, or PDTA144VE equivalent, this page delivers verified electrical parameters, validated SOT416 pin configuration, real-world use cases in interface and driver circuits, and two confirmed alternative parts with documented functional and packaging differences.

Technical Context

The PDTA144VE integrates two precision thin-film resistors (R1 = 47 kΩ ±28%, R2/R1 = 0.21 ±21%) directly into a monolithic PNP bipolar die, eliminating external bias components and reducing PCB footprint. Its internal resistor network enables direct TTL/CMOS-compatible input drive without external pull-up or current-limiting resistors.

Designed for DC switching-not linear amplification-it exhibits guaranteed h_FE ≥ 40 at V_CE = −5 V and I_C = −5 mA, with V_I(on) = −3.8 V (typ) and V_I(off) = −3.1 V (typ), supporting reliable on/off control across −40 °C to +100 °C ambient operation.

FAQ

What is the exact package type and dimensions of PDTA144VE?

PDTA144VE uses the SOT416 (SC-75) package: a plastic surface-mounted outline with 3 leads, body dimensions 1.6 mm × 0.8 mm × 0.55 mm, and 0.8 mm lead pitch. This ultra-small footprint is defined in JEDEC MO-203 and JEITA ED-7388 standards, and is compatible only with reflow soldering-not wave or hand soldering.

Does PDTA144VE require external bias resistors in typical switching applications?

No. PDTA144VE integrates R1 = 47 kΩ and R2 = 10 kΩ (R2/R1 = 0.21) internally, enabling direct connection to logic outputs without external components. The built-in network ensures stable saturation and eliminates variability from discrete resistor tolerances or layout parasitics-verified per Table 2 and Table 8 in the official datasheet.

What is the maximum continuous output current rating for PDTA144VE?

The PDTA144VE is rated for −100 mA DC output current (I_O) under normal operating conditions, as specified in Table 2 (Quick reference data) and Table 6 (Limiting values). This rating applies at T_amb ≤ 25 °C with standard mounting; derating is required above ambient temperatures per the thermal resistance R_th(j-a) = 833 K/W.

Can PDTA144VE be used in linear amplifier configurations?

No. PDTA144VE is characterized and qualified exclusively for switching applications. Its datasheet specifies no h_FE linearity, frequency response, or small-signal parameters. The integrated resistors and guaranteed V_CEsat/V_I(on) values confirm its intended use as a saturated switch-not a linear amplifier-per Section 1.3 (Applications) and Figure 1–4.

What is the marking code printed on the PDTA144VE package?

The PDTA144VE is marked with the code "13" on its top surface, as confirmed in Table 5 (Marking codes) of the official product data sheet. This 2-character alphanumeric code uniquely identifies the PDTA144VE variant within the PDTA144V series and is laser-etched or molded onto the SOT416 body.
