Nexperia USA Inc. PBLS6024D,115

Overview

PBLS6024D from Nexperia is a dual-function PNP/NPN load switch IC in a single TSOP6 (SOT457) package, integrating a 60 V, 1.5 A PNP low-V_CEsat transistor (TR1) and a 50 V, 100 mA NPN resistor-equipped transistor (TR2). It serves as a high-side supply switch with integrated bias network, enabling compact battery charger and LED backlight control in portable automotive-grade systems.

For engineers reviewing the PBLS6024D datasheet, PBLS6024D pinout, PBLS6024D application, or PBLS6024D equivalent, this device offers AEC-Q101 qualification, verified R_CEsat ≤ 175 mΩ at −1.5 A, dual-transistor functional integration, and validated thermal derating on FR4 and ceramic PCBs - critical for space-constrained, thermally demanding load-switch designs.

Technical Context

The PBLS6024D implements a monolithic dual-transistor architecture: TR1 operates as a high-side PNP switch with V_CEO = −60 V, I_C = −1.5 A, and R_CEsat = 110–175 mΩ at −1.5 A/−100 mA drive; TR2 functions as an integrated driver stage with R₁ = 15.4–28.6 kΩ and R₂/R₁ = 0.8–1.2, enabling direct logic-level input control without external biasing.

Its switching behavior is characterized by t_on = 55 ns and t_off = 415 ns under −10 V V_CC, −1 A I_C, and ±50 mA base drive, with thermal resistance R_th(j-a) ranging from 165 K/W (ceramic) to 260 K/W (standard FR4), supporting operation from −55 °C to +150 °C junction temperature.

FAQ

What is the maximum continuous current rating for the PNP transistor (TR1) in PBLS6024D?

The PBLS6024D's PNP transistor (TR1) is rated for −1.5 A continuous collector current at T_amb ≤ 25 °C, with peak capability of −3 A for pulses ≤1 ms. Derating applies above 25 °C ambient per Figure 1's power curve; at 85 °C ambient on FR4 PCB, usable current drops to ~900 mA to maintain T_j ≤ 150 °C.

Can PBLS6024D be used in a low-side switching configuration?

No - PBLS6024D is architected exclusively for high-side switching. Its PNP transistor (TR1) has emitter (Pin 6) intended for connection to the positive supply rail and collector (Pin 5) for the load. Using it as a low-side switch would reverse bias the internal structures and violate absolute maximum ratings, risking permanent damage.

How does the integrated resistor-equipped transistor (TR2) simplify circuit design?

TR2 integrates R₁ (15.4–28.6 kΩ) and R₂/R₁ (0.8–1.2) to form a precision current-limited driver stage. This eliminates the need for two external base resistors and a discrete NPN transistor to drive TR1's base, reducing layout area by >2.5 mm² and removing three solder joints subject to failure in vibration-prone environments.

Is thermal pad connection required for reliable operation at full 1.5 A load?

While not mandatory, connecting Pin 4 (GND) and the thermal pad (if present per PCB layout) to a solid ground plane significantly improves thermal performance. On standard FR4, R_th(j-a) drops from 260 K/W to 211 K/W with a 1 cm² collector pad - enabling sustained 1.5 A operation at up to 65 °C ambient instead of the 25 °C limit with minimal copper.
