Nexperia USA Inc. PBLS2024D,115

Overview

PBLS2024D,115 from NXP Semiconductors is a dual-function SOT457-packaged discrete device 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 = 78–117 mΩ at −1.8 A and R₁ = 22 kΩ ±25%. It serves as a compact high-side load switch in automotive LED backlighting and battery charging circuits.

For engineers reviewing the PBLS2024D,115 datasheet, PBLS2024D,115 pinout, PBLS2024D,115 application, or PBLS2024D,115 equivalent, this dual-transistor solution enables space-constrained high-side switching with integrated biasing, low saturation voltage, AEC-Q101 qualification, and verified thermal performance on FR4 PCBs.

Technical Context

The PBLS2024D integrates two functionally independent transistors: TR1 is a PNP BISS device optimized for high-current, low-loss switching with V_CEsat as low as −140 mV at −1.8 A/−100 mA drive; TR2 is an NPN RET with built-in R₁ = 22 kΩ and R₂/R₁ = 1.0 ±0.2, enabling direct logic-level control without external bias resistors.

TR1 operates with DC current gain h_FE = 160–260 at −1.8 A and −2 V V_CE, while TR2 provides VI(on) = 1.7–2.5 V and VI(off) = 0.8–1.1 V, supporting robust digital interface compatibility. Both sections share thermal coupling but maintain separate electrical paths and absolute maximum ratings.

FAQ

What is the maximum continuous current rating for the PNP BISS transistor (TR1) in PBLS2024D,115?

The TR1 section is rated for −1.8 A continuous collector current at T_amb ≤ 25 °C with standard FR4 mounting. Derating applies above 25 °C per the 211 K/W thermal resistance curve; at 85 °C ambient, maximum continuous current drops to approximately −1.2 A to maintain junction temperature below 150 °C.

Can PBLS2024D,115 be used as a standalone high-side switch without external resistors?

Yes-the TR2 section includes fully integrated R₁ = 22 kΩ and R₂/R₁ = 1.0 ±0.2, allowing direct connection of a 3.3 V or 5 V GPIO to pin 2 for logic-controlled switching. TR1 still requires appropriate base drive (e.g., via TR2 output or external driver) but needs no external biasing components.

Is PBLS2024D,115 pin-compatible with other SOT457 dual-transistor devices?

No-PBLS2024D,115 has a unique 6-pin pinout defined in Table 2: pins 1/5/6 serve TR1 (base/collector/emitter), while pins 2/3/4 serve TR2 (base/collector/emitter). Competing SOT457 dual transistors use different internal mappings; mechanical fit does not guarantee functional or electrical compatibility.

How does the AEC-Q101 qualification impact design validation for PBLS2024D,115?

AEC-Q101 qualification confirms PBLS2024D,115 has passed stress tests including HTGB, HTRB, TC, and ESD up to ±8 kV HBM-eliminating need for duplicate qualification testing in automotive programs. It supports PPAP submission and satisfies Tier 1 supplier requirements for discrete semiconductors in safety-related modules.
