Nexperia USA Inc. PBLS1502Y,115

Overview

PBLS1502Y,115 from NXP Semiconductors is a dual-function discrete load switch integrating a low-V_CEsat PNP BISS transistor (TR1) and an NPN resistor-equipped transistor (TR2) in a single SOT363 (SC-88) package. It delivers −500 mA DC collector current capability for the PNP switch, 300–500 mΩ equivalent on-resistance at −500 mA/−50 mA drive, and supports high-side switching for LED backlights and battery chargers with <1 V input threshold voltage.

For engineers reviewing the PBLS1502Y,115 datasheet, PBLS1502Y,115 pinout, PBLS1502Y,115 application, or PBLS1502Y,115 equivalent, this device serves as a space-saving, low-drive-power solution for portable equipment supply-line switching where component count reduction and thermal efficiency in FR4 PCB layouts are critical design requirements.

Technical Context

The PBLS1502Y,115 integrates two functionally distinct transistors: TR1 is a PNP BISS (Breakdown-Immune Self-Saturating) transistor rated for −15 V V_CEO and −500 mA I_C, optimized for low-saturation operation with V_CEsat = −250 mV at −500 mA/−50 mA drive. TR2 is an NPN resistor-equipped transistor (RET) with integrated R1 = 4.7 kΩ (typ) and R2/R1 = 1 (typ), enabling direct logic-level control without external biasing.

Its dual-transistor architecture enables coordinated high-side switching: TR1 handles main load current while TR2 acts as a driver stage with VI(on) = 1.9 V (typ) at 20 mA output, and VI(off) = 1.1 V (min) ensures robust turn-off under noisy conditions. Thermal resistance R_th(j-a) is 416 K/W on standard FR4, supporting continuous operation up to T_j = 150 °C.

FAQ

What is the maximum continuous current the PBLS1502Y,115 can switch in high-side configuration?

The PBLS1502Y,115 supports −500 mA DC collector current for its PNP transistor (TR1) under standard FR4 PCB conditions with T_amb ≤ 25 °C. At this current, R_CEsat is 300–500 mΩ, resulting in ≤0.25 W conduction loss. Derating is required above 25 °C ambient per the 416 K/W junction-to-ambient thermal resistance.

Can the PBLS1502Y,115 be driven directly from a 1.8 V GPIO without additional circuitry?

Yes. The NPN RET stage (TR2) has VI(on) = 1.9 V (typ) and VI(off) = 1.1 V (min), providing sufficient margin for reliable turn-on from a 1.8 V logic signal. Its integrated R1/R2 network eliminates external bias resistors, enabling true single-pin logic control.

How does the PBLS1502Y,115 handle reverse voltage conditions on the collector of TR1?

TR1 is rated for V_CEO = −15 V and V_CBO = −15 V, meaning it blocks up to −15 V reverse voltage at the collector with base open. This protects downstream circuits during battery insertion/removal or charger IC fault conditions where the collector may float negative relative to emitter.

Is the PBLS1502Y,115 RoHS compliant and halogen-free?

Yes. Per NXP's official product documentation and packaging data, PBLS1502Y,115 conforms to RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The "115" suffix in the ordering code indicates tape-and-reel packaging compliant with these environmental standards.
