Nexperia USA Inc. PDTC114EMB,315

Overview

PDTC114EMB from Nexperia is an NPN resistor-equipped transistor (RET) in a leadless DFN1006B-3 (SOT883B) package, designed for digital switching in space-constrained PCBs. It integrates 10 kΩ input and feedback bias resistors (R1 = R2 = 10 kΩ), supports 100 mA output current, exhibits 150 mV V_CE(sat) at I_C = 10 mA/I_B = 0.5 mA, and is AEC-Q101 qualified for automotive use - deployed in mobile peripheral drivers and IC input control circuits.

For engineers reviewing the PDTC114EMB datasheet, PDTC114EMB pinout, PDTC114EMB application, or PDTC114EMB equivalent, key selection criteria include built-in resistor ratio (R2/R1 = 0.8–1.2), ultra-low profile (0.37 mm height), thermal resistance (500 K/W), and compatibility with FR4 PCB reflow footprints per SOT883B standard.

Technical Context

This RET replaces discrete BJT + two external bias resistors in digital logic interface circuits. Its integrated R1–R2 network establishes fixed base drive and feedback, enabling direct connection to 3.3 V/5 V GPIO outputs without external components while maintaining stable saturation under varying temperature (−40 °C to 150 °C junction).

The device operates as a single-stage digital switch with defined VI(on)/VI(off) thresholds (1.8–2.5 V on-state, 0.8–1.1 V off-state), low collector capacitance (2.5 pF), and 230 MHz f_T, supporting fast edge transitions in low-power signal routing applications.

FAQ

What is the maximum allowable continuous collector current for PDTC114EMB?

The absolute maximum continuous collector current is 100 mA, as specified in the limiting values table. Operation at this current requires adherence to the power derating curve: total power dissipation must remain ≤250 mW at T_amb ≤25 °C and decreases linearly to zero at 150 °C ambient, assuming FR4 PCB mounting with standard footprint.

Can PDTC114EMB be used with 1.8 V logic inputs?

No - its VI(on) threshold is specified as 1.8–2.5 V (typical 2.5 V at I_C = 10 mA), meaning reliable turn-on requires ≥2.5 V input under typical conditions. For 1.8 V systems, PDTC124EMB (VI(on) ≈ 1.4 V) or discrete BJT solutions are recommended.

Is thermal pad connection required for PDTC114EMB's DFN1006B-3 package?

No - the DFN1006B-3 (SOT883B) package has no exposed thermal pad. Heat dissipation occurs solely through the three soldered terminals into the PCB copper, resulting in a junction-to-ambient thermal resistance of 500 K/W on standard FR4.

How does the R2/R1 ratio affect switching behavior in PDTC114EMB?

The R2/R1 ratio of 0.8–1.2 sets the internal feedback fraction, stabilizing the transistor's operating point against β variation and temperature drift. This ensures consistent saturation depth and predictable VI(off) levels, eliminating need for external emitter degeneration resistors in digital switching applications.
