Nexperia USA Inc. PDTA114EM,315

Overview

PDTA114EM from Nexperia is a PNP resistor-equipped transistor (RET) in SOT883 (DFN1006-3) package, rated for −50 V V_CEO, −100 mA I_O, with integrated R₁ = 10 kΩ and R₂ = 10 kΩ bias resistors; used as a digital switch for IC input control and load switching in automotive and industrial modules.

For engineers reviewing the PDTA114EM datasheet, PDTA114EM pinout, PDTA114EM application, or PDTA114EM equivalent, this device serves as an AEC-Q101-qualified, space-constrained PNP switching solution requiring no external base resistors, with verified thermal derating up to 150 °C junction temperature and defined off-state input voltage (−1.1 V to −0.8 V) for reliable logic-level interfacing.

Technical Context

This RET integrates a PNP bipolar transistor with two monolithically embedded silicon resistors-R₁ connected between input and base, R₂ between base and emitter-enabling single-pin digital drive without discrete bias components. Its simplified topology eliminates base current calculation and reduces PCB footprint versus discrete BJT + resistor solutions.

The device operates with guaranteed DC current gain (h_FE) ≥30 at −5 V V_CE and −5 mA I_C, delivers ≤−150 mV V_CEsat at −10 mA I_C/−0.5 mA I_B, and maintains stable off-state behavior with VI(off) between −1.1 V and −0.8 V under −5 V V_CE and −100 µA I_C.

FAQ

Is PDTA114EM compatible with lead-free reflow soldering processes?

Yes, PDTA114EM is qualified exclusively for reflow soldering per its datasheet. The SOT883 package uses lead-free terminations and meets JEDEC J-STD-020 moisture sensitivity level 1 requirements. Reflow profiles must follow Nexperia's recommended thermal profile for DFN1006-3, with peak temperature ≤260 °C and time above 217 °C limited to 60–150 seconds.

What is the maximum ambient temperature for continuous operation at full 100 mA load?

At full −100 mA output current, continuous operation is limited to T_amb ≤ 75 °C on a standard FR4 PCB with 70 µm copper trace, based on the 250 mW P_tot rating and 500 K/W R_th(j-a). Derating is required above 25 °C ambient per Figure 1; at 75 °C ambient, maximum allowable power drops to ~125 mW, supporting −100 mA only if V_CEsat remains ≤−125 mV.

Can PDTA114EM replace BC847B in existing designs without layout changes?

No-PDTA114EM uses a 3-pin DFN1006-3 (SOT883) package (1.0 × 0.6 mm), whereas BC847B is typically in SOT23 (3.0 × 1.4 mm). Direct replacement requires PCB redesign. However, it replaces the BC847B + two 10 kΩ resistors functionally, reducing total board area and assembly steps despite different footprint.

Does PDTA114EM support PWM switching at frequencies above 10 kHz?

Yes-its built-in transistor has f_T = 180 MHz (typical), and V_CEsat remains stable up to 100 mA. At 10 kHz PWM with 50 % duty cycle, switching losses are negligible due to fast turn-on/off times (<100 ns typical), provided gate drive rise/fall times are ≤1 µs and layout minimizes parasitic inductance in the collector path.
