NXP Semiconductors PBLS2023D,115

Overview

PBLS2023D from Nexperia is a dual-function SOT457 (SC-74) surface-mount semiconductor integrating a PNP low-V_CEsat Breakthrough In Small Signal (BISS) transistor (TR1) and an NPN resistor-equipped transistor (RET, TR2). It delivers −20 V V_CEO, −1.8 A I_C for TR1, 50 V V_CEO and 100 mA I_O for TR2, with R_CEsat as low as 78 mΩ at −1.8 A - enabling high-efficiency high-side load switching in space-constrained portable and automotive power rails.

For engineers reviewing the PBLS2023D datasheet, PBLS2023D pinout, PBLS2023D application, or PBLS2023D equivalent, this device supports critical design tasks including supply-line switching, LED backlight control, battery charger path management, and AEC-Q101-compliant high-side driver integration - all within a single 6-pin TSOP6 footprint.

Technical Context

The PBLS2023D integrates two functionally independent transistors on one die: TR1 operates as a PNP BISS switch optimized for low-saturation voltage and high current handling (−1.8 A), while TR2 functions as an NPN RET with integrated bias resistors (R1 = 10 kΩ, R2/R1 = 1) for simplified digital input interfacing. Both share thermal coupling but maintain electrically isolated collector-emitter paths.

TR1's BISS architecture achieves V_CEsat down to −140 mV at −1.8 A/−100 mA drive, outperforming standard PNP BJTs; TR2 provides VI(on) = 1.8 V and VI(off) = 1.1 V thresholds, enabling direct connection to 1.8–3.3 V logic without external biasing. The device is qualified per AEC-Q101 for automotive underhood and infotainment applications.

FAQ

What is the maximum junction temperature and thermal resistance of PBLS2023D?

The absolute maximum junction temperature is 150 °C. Thermal resistance from junction to ambient (R_th(j-a)) is 260 K/W on standard FR4 PCB, 211 K/W with 1 cm² collector pad, and 165 K/W on ceramic Al₂O₃ substrate - enabling 370–630 mW total power dissipation depending on board layout.

Can PBLS2023D be used as a standalone high-side switch without external components?

Yes - TR1 operates as a fully functional high-side PNP BISS switch with only base drive required; TR2's integrated R1/R2 bias network allows direct connection to 1.8–5 V logic. No external resistors, capacitors, or level shifters are needed for basic on/off control.

How does the AEC-Q101 qualification impact PBLS2023D's use in non-automotive designs?

AEC-Q101 qualification ensures robustness against temperature cycling, humidity, mechanical shock, and ESD - making PBLS2023D equally suitable for industrial, medical, and aerospace applications demanding high reliability, even outside automotive contexts.

What is the switching speed performance of TR1 in PBLS2023D?

TR1 achieves t_d = 17 ns, t_r = 33 ns, t_on = 50 ns, t_s = 270 ns, t_f = 60 ns, and t_off = 330 ns under −10 V V_CC, −1 A I_C, and ±50 mA base drive - supporting PWM frequencies up to 2 MHz in high-efficiency DC-DC and LED driver topologies.
