Nexperia USA Inc. PDTC114EQAZ

Overview

PDTC114EQAZ from Nexperia is a 100 mA, 50 V NPN resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) ultra-small surface-mount package with visible side pads. It integrates 10 kΩ input and 10 kΩ base-emitter bias resistors, delivers 150 mV V_CE(sat) at I_C = 10 mA / I_B = 0.5 mA, and is AEC-Q101 qualified for automotive digital switching applications.

For engineers reviewing the PDTC114EQAZ datasheet, PDTC114EQAZ pinout, PDTC114EQAZ application, or PDTC114EQAZ equivalent, this device serves as a space-optimized, component-count-reducing replacement for discrete BJT + bias resistor networks in logic-level interface and load switching circuits requiring stable DC gain (h_FE ≥ 30 at I_C = 5 mA) and low-profile mounting.

Technical Context

This NPN RET uses an integrated silicon transistor with built-in R1 (10 kΩ) and R2 (10 kΩ) bias resistors to form a single-input, single-output active switch. Its internal configuration eliminates external base resistors while maintaining predictable turn-on (V_I(on) = 1.8–2.5 V) and turn-off (V_I(off) = 0.8–1.1 V) thresholds across temperature.

The DFN1010D-3 package features solderable side pads for optical inspection and thermal enhancement, supporting 280 mW power dissipation on single-layer FR4 and 440 mW on 4-layer PCBs. Its f_T of 230 MHz enables reliable operation in high-speed digital switching up to ~10 MHz.

FAQ

What is the maximum continuous collector current for PDTC114EQAZ?

The absolute maximum continuous collector current is 100 mA, as specified in Table 2 (Quick reference data) and Table 6 (Limiting values). This rating applies at T_amb ≤ 25 °C on a standard FR4 PCB; derating is required above 25 °C per Figure 2's power derating curve, reaching zero at ~150 °C ambient.

How does the internal resistor network affect drive requirements?

The integrated 10 kΩ R1 and 10 kΩ R2 resistors enable direct connection to 3.3 V or 5 V logic outputs without external biasing. VI(on) is 1.8–2.5 V and VI(off) is 0.8–1.1 V, allowing clean switching with standard CMOS/TTL levels while suppressing noise-induced turn-on via the R2 feedback path.

Is PDTC114EQAZ compatible with reflow soldering processes?

Yes - the DFN1010D-3 package is qualified for standard lead-free reflow profiles (J-STD-020). Figure 32 provides the recommended solder land pattern, and the device supports peak temperatures up to 260 °C. Side-pad geometry ensures robust solder joint formation and AOI compatibility.

Can PDTC114EQAZ replace BC847-type transistors directly?

It serves as a functional drop-in alternative in digital switching roles (e.g., logic buffers, LED drivers), but not pin-compatible: PDTC114EQAZ uses a 4-pin DFN layout (I/GND/O/O), whereas BC847 uses 3-pin SOT23 (C/B/E). Layout redesign is required, though BOM count and assembly cost decrease due to eliminated bias resistors.
