Nexperia USA Inc. PDTA113ZU,115

Overview

PDTA113ZU from NXP Semiconductors is a PNP resistor-equipped transistor in SOT323 (SC-70) package, designed for general-purpose switching and interface applications with built-in bias resistors R1 = 1 kΩ and R2/R1 = 10. It delivers −100 mA DC output current, −50 V collector-emitter voltage rating, and −150 mV saturation voltage at IC = −10 mA/IB = −0.5 mA - enabling compact logic-level driven switching in space-constrained PCBs.

For engineers reviewing the PDTA113ZU datasheet, PDTA113ZU pinout, PDTA113ZU application, or PDTA113ZU equivalent, this device serves as a drop-in replacement for discrete base-bias resistor networks in level-shifting, inverter, and digital I/O driver circuits where simplified BOM and reduced placement cost are critical.

Technical Context

This PNP transistor integrates two precision on-die resistors (R1 = 1 kΩ, R2 = 10 kΩ) to form a fixed-current bias network, eliminating external components required for standard BJT switching. Its internal resistor ratio ensures stable gain control and predictable turn-on/off thresholds across temperature.

The device operates with VI(on) = −0.95 V typical at IC = −20 mA and VI(off) = −0.65 V at IC = −100 µA, supporting direct interfacing with 3.3 V and 5 V CMOS/TTL logic families without additional level translation. Thermal resistance Rth(j-a) is 625 K/W in free air, consistent with SC-70 thermal performance limits.

FAQ

What is the maximum operating temperature for PDTA113ZU?

The junction temperature (Tj) limit is 150 °C, and ambient temperature (Tamb) range is −65 °C to +150 °C. Derating begins above 25 °C ambient at 1.6 mW/°C based on its 200 mW total power dissipation rating and 625 K/W thermal resistance. Operation beyond these limits risks permanent parametric shift or failure.

Can PDTA113ZU replace a standard PNP BJT like BC807 in existing designs?

Yes, but only if the circuit uses external base resistors and the load configuration matches high-side switching. PDTA113ZU's integrated R1/R2 network eliminates those resistors, so direct substitution requires removing them and verifying VI(on)/VI(off) compatibility with the driving source - typically 3.3 V or 5 V logic.

Is PDTA113ZU RoHS compliant and halogen-free?

Yes. As a 2009 NXP product, PDTA113ZU conforms to RoHS Directive 2011/65/EU and is manufactured with halogen-free molding compounds per IEC 61249-2-21. Full compliance documentation is available via NXP's official product page and material declarations.

What is the marking code for PDTA113ZU on the package?

The top-side marking is *16 - where the asterisk denotes manufacturing location (Hong Kong, Malaysia, or China per Table 4), and "16" is the unique identifier for PDTA113ZU in the SOT323 package. This matches NXP's standardized marking scheme for the PDTA113Z series.
