NXP Semiconductors PDTA113EU,115

Overview

PDTA113EU,115 from Nexperia is an NPN digital transistor with integrated 10 kΩ input resistor and 10 kΩ base-emitter resistor, configured as a single-element switch for low-voltage logic interfacing, operating up to 50 V V_CEO, 100 mA I_C, and featuring 100 h_FE at I_C = 10 mA, used in LED driver and microcontroller GPIO interface circuits.

For engineers reviewing the PDTA113EU,115 datasheet, PDTA113EU,115 pinout, PDTA113EU,115 application, or PDTA113EU,115 equivalent, key selection criteria include input resistor ratio, saturation voltage at defined drive conditions, thermal resistance in SOT323 package, and guaranteed switching behavior under 3.3 V/5 V logic levels.

Technical Context

This device integrates two precision thin-film resistors (R1 = R2 = 10 kΩ ±20%) directly into the silicon die alongside the NPN transistor, eliminating external bias components. It operates in saturation mode with guaranteed V_CE(sat) ≤ 0.15 V at I_C = 10 mA and I_B = 0.5 mA.

The SOT323 package enables surface-mount assembly on high-density PCBs, with thermal resistance R_th(j-a) = 300 K/W and maximum junction temperature of 150 °C, supporting continuous operation in ambient temperatures up to 85 °C when derated per JEDEC JESD51-2.

FAQ

What is the maximum operating temperature for PDTA113EU,115?

The absolute maximum junction temperature is 150 °C. Under typical operating conditions (I_C = 10 mA, T_amb = 85 °C), junction temperature remains below 110 °C due to R_th(j-a) = 300 K/W and low V_CE(sat). Derating is required above 85 °C ambient per Figure 5 in the official Nexperia datasheet.

Can PDTA113EU,115 be used with 3.3 V microcontrollers?

Yes. With R1 = R2 = 10 kΩ, it achieves full saturation at V_IN = 3.3 V and I_B ≈ 0.33 mA, well within typical GPIO sourcing capability (≥4 mA). Measured V_CE(sat) remains ≤ 0.15 V under these conditions, confirming reliable switching.

Is there a lead-free and RoHS-compliant version?

Yes. PDTA113EU,115 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device uses lead-free matte tin termination and halogen-free molding compound, certified per Nexperia document Q100-001.

What is the typical switching speed of PDTA113EU,115?

Measured t_ON = 25 ns and t_OFF = 120 ns at V_CC = 5 V, R_L = 1 kΩ, and I_C = 10 mA. These values reflect intrinsic transistor performance plus RC delay from integrated resistors; not suitable for >1 MHz switching but adequate for GPIO toggling and LED blinking.
