Nexperia USA Inc. PDTB114ETR

Overview

PDTB114ETR from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 (TO-236AB) package, designed for digital switching applications with built-in 10 kΩ input bias resistor (R1) and 10 kΩ base-emitter resistor (R2), −50 V V_CEO, −500 mA I_O, and AEC-Q101 qualification for automotive use.

For engineers reviewing the PDTB114ETR datasheet, PDTB114ETR pinout, PDTB114ETR application, or PDTB114ETR equivalent, key selection criteria include its integrated bias network ratio (R2/R1 = 1.0 ± 0.1), low V_CE(sat) of −100 mV at −50 mA/−2.5 mA, high-temperature operation up to 175 °C, and direct replacement capability for discrete BJT + resistor solutions in logic-level interface circuits.

Technical Context

This PNP RET integrates two precision thin-film resistors (R1 = 10 kΩ, R2 = 10 kΩ) directly on-die to form a monolithic current-limiting input stage, eliminating external bias components and reducing PCB footprint. Its internal transistor exhibits h_FE ≥ 70 at −50 mA/−5 V and f_T = 140 MHz, enabling reliable switching up to several MHz.

The device operates with VI(on) = −1.0 to −3.0 V and VI(off) = −0.6 to −1.5 V, ensuring robust noise immunity in 3.3 V and 5 V digital systems. Thermal resistance R_th(j-a) is 327 K/W on 4-layer FR4, supporting continuous operation at ambient temperatures up to +175 °C when derated per Fig 1.

FAQ

What is the maximum allowable input voltage (VI) for PDTB114ETR?

The absolute maximum input voltage is −50 V (negative-going) and +10 V (positive-going), as specified in Table 6. Exceeding these values risks permanent damage to the on-die bias resistors or transistor junction. For reliable operation, keep VI within −30 V to +7 V in normal use, with typical logic drive centered at 0 V to −3.3 V.

Can PDTB114ETR replace BC807-40 in existing designs without layout changes?

No-PDTB114ETR has different pinout (input/base on pin 1, emitter/GND on pin 2, collector/output on pin 3), whereas BC807-40 uses emitter-collector-base (ECB) order in SOT23. Direct replacement requires PCB redesign. However, it replaces the *combination* of BC807-40 + two external resistors, reducing total component count and footprint.

Is thermal derating required for continuous operation at 100 °C ambient?

Yes. At T_amb = 100 °C, P_tot must be derated from 460 mW (4-layer PCB) to ~280 mW per Fig 1. This corresponds to max I_O ≈ −375 mA at V_CE(sat) = −100 mV. Full −500 mA rating applies only at T_amb ≤ 25 °C unless heatsinking or forced airflow is used.

Does PDTB114ETR support PWM switching at 20 kHz?

Yes. With f_T = 140 MHz and typical switching times in the 10–20 ns range (inferred from V_CE(sat) and h_FE data), PDTB114ETR fully supports 20 kHz PWM for motor and LED dimming. Ensure gate drive strength meets VI(on)/VI(off) thresholds and layout minimizes parasitic inductance on pin 1 and pin 3 traces.
