Nexperia USA Inc. PDTA114YMB,315

Overview

PDTA114YMB from Nexperia is a PNP resistor-equipped transistor (RET) in a leadless DFN1006B-3 (SOT883B) package, designed as a single-chip digital switch with integrated 10 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2). It delivers −100 mA output current, −50 V collector-emitter voltage rating, and AEC-Q101 qualification for automotive-grade reliability in low-power peripheral control circuits.

For engineers reviewing the PDTA114YMB datasheet, PDTA114YMB pinout, PDTA114YMB application, or PDTA114YMB equivalent, this device serves as a space-optimized, bias-resistor-integrated replacement for discrete PNP + two-resistor configurations in digital logic interfacing, IC input control, and mobile power management where board area and assembly cost are critical.

Technical Context

This RET integrates a PNP bipolar transistor with precisely trimmed on-die R1 = 10 kΩ (input) and R2 = 47 kΩ (base-emitter feedback), yielding an R2/R1 ratio of 4.7 (typical). Its operation eliminates external bias components while maintaining predictable DC current gain (hFE ≥ 100 at −5 mA IC) and low saturation voltage (VCEsat ≤ −100 mV).

The device operates within −65 °C to +150 °C ambient range, supports −100 mA continuous output, and features ultra-low profile (0.37 mm height) for thin-profile portable electronics. Thermal resistance Rth(j-a) is 500 K/W on standard FR4 PCB, enabling stable performance in thermally constrained layouts without heatsinking.

FAQ

What is the maximum operating temperature for PDTA114YMB?

The junction temperature limit is 150 °C, and the ambient operating range is −65 °C to +150 °C. Derating begins above 25 °C ambient per the published power derating curve: total power dissipation drops linearly from 250 mW at 25 °C to 0 mW at 175 °C on standard FR4 PCB.

Can PDTA114YMB drive a 5 V logic input directly?

Yes-it functions as an inverting digital switch: applying ≥1.4 V to Pin 1 (input) turns the PNP on, pulling Pin 3 (collector) to near ground. With VCE = −0.3 V and IC = −1 mA, VI(on) is −0.8 V (typ), ensuring clean logic-low assertion into 5 V CMOS inputs with appropriate pull-up.

Is thermal pad connection required for DFN1006B-3 package?

No-the DFN1006B-3 (SOT883B) has no exposed thermal pad; thermal dissipation relies on solder joints and PCB copper. The specified Rth(j-a) = 500 K/W assumes standard FR4 footprint with single-sided 1 oz copper, no additional thermal vias or pads needed for ≤250 mW operation.

How does the built-in R2 resistor affect switching behavior?

R2 provides base-emitter feedback that accelerates turn-off by discharging base charge during transition. With R2 = 47 kΩ, it ensures reliable cutoff even with slow-rising input edges, reducing shoot-through risk in multi-stage logic and improving noise immunity over single-resistor bias schemes.
