Nexperia USA Inc. PBLS4002Y,115

Overview

PBLS4002Y from Nexperia is a dual-function discrete load switch combining a 40 V, −500 mA PNP low-V_CEsat transistor (TR1) and a 50 V, 100 mA NPN resistor-equipped transistor (TR2) in a single SOT363 (TSSOP6) package. It serves as a high-side supply switch and integrated driver for LED backlights, battery chargers, and portable equipment power rails, with R_CEsat = 440–700 mΩ and input bias resistors R1 = 4.7 kΩ (typ), R2/R1 = 1.

For engineers reviewing the PBLS4002Y datasheet, PBLS4002Y pinout, PBLS4002Y application, or PBLS4002Y equivalent, this device delivers verified dual-transistor functionality in ultra-compact SMT packaging - critical for space-constrained portable designs requiring low drive voltage (<1 V), reduced component count, and stable high-side switching performance.

Technical Context

The PBLS4002Y integrates two independent transistor functions on one die: TR1 operates as a PNP high-side switch with V_CEO = −40 V, I_Clim = −500 mA, and V_CEsat ≤ −350 mV at −500 mA/−50 mA drive; TR2 functions as an NPN RET with V_CEO = 50 V, I_O = 100 mA, and built-in R1 = 4.7 kΩ (typ), R2/R1 = 1.0 (typ).

Both transistors share thermal coupling within the SOT363 package but operate electrically isolated: TR1's emitter (Pin 1) and TR2's emitter (Pin 4) are separate ground terminals, enabling independent biasing and load referencing. The device supports pulsed operation up to δ ≤ 0.02 and T_j ≤ 150 °C, with total device P_tot = 300 mW.

FAQ

What is the maximum continuous current rating for the PNP transistor (TR1) in PBLS4002Y?

The PNP transistor (TR1) has a limiting collector current (I_Clim) of −500 mA under specified pulsed conditions (t_p ≤ 300 µs, δ ≤ 0.02). For continuous DC operation, derating applies: at T_amb = 25 °C on FR4 PCB, maximum sustainable current is approximately −300 mA due to thermal limits (P_tot = 300 mW, R_CEsat ≈ 570 mΩ typ).

Can PBLS4002Y be used with 1.8 V GPIOs to control the PNP switch?

Yes. TR1's V_BEon is ≤ −1.1 V at −100 mA, and its low-threshold design ensures reliable turn-on with 1.8 V logic: applying 0 V to Pin 2 (B1) achieves full saturation when V_CC ≤ 24 V. No level shifter is required, making it compatible with modern ultra-low-voltage MCUs.

How does the integrated resistor network in TR2 affect timing performance?

The fixed R1 = 4.7 kΩ and R2/R1 = 1.0 ratio ensure consistent base current and predictable switching speed: t_on/t_off remains stable across temperature (−55 °C to 150 °C) and supply voltage (0–30 V), with typical V_I(on) = 1.9 V and V_I(off) = 1.1 V - enabling sub-microsecond enable/disable transitions without external timing components.

Is PBLS4002Y qualified for automotive applications?

No. Per Nexperia's revision history (v.5, Jan 2023), PBLS4002Y is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia recommends the −Q qualified variant PBLS4002Y-Q, which undergoes extended temperature cycling, HTOL, and ESD validation per automotive standards.
