Nexperia USA Inc. PBLS2002D,115

Overview

PBLS2002D,115 from Nexperia is a dual-function SOT457-packaged discrete device integrating a PNP low-V_CEsat Breakthrough in Small Signal (BISS) transistor and an NPN resistor-equipped transistor (RET). It delivers −20 V V_CEO (TR1), 50 V V_CEO (TR2), 185–280 mΩ R_CEsat at −1 A, 4.7 kΩ R1 bias resistor, and 1:1 R2/R1 ratio - enabling high-side load switching and logic-level-driven output control in space-constrained portable power rails.

For engineers reviewing the PBLS2002D,115 datasheet, PBLS2002D,115 pinout, PBLS2002D,115 application, or PBLS2002D,115 equivalent, key selection criteria include verified dual-transistor integration, confirmed 6-pin SOT457 mapping, validated −1 A DC collector current capability for TR1, and documented 100 mA output current rating for TR2 - all critical for battery charger switch and LED backlight driver design.

Technical Context

The PBLS2002D integrates two functionally independent transistors: TR1 is a PNP BISS device optimized for low-saturation switching with V_CEsat as low as −185 mV at −1 A/−100 mA drive; TR2 is an NPN RET with integrated 4.7 kΩ input bias resistor and matched R2/R1 = 1.0, enabling direct microcontroller GPIO interfacing without external base resistors.

TR1 operates as a high-side load switch with −20 V V_CEO, −1 A I_C, and 155–220 h_FE at −1 A; TR2 functions as a buffered logic-level output stage with 50 V V_CEO, 100 mA I_O, and VI(on) = 1.9–2.5 V - both sharing thermal coupling on a single die but electrically isolated with separate emitter, base, and collector terminals.

FAQ

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

The PBLS2002D,115 TR1 section supports −1 A DC collector current at T_amb ≤ 25 °C with standard FR4 PCB mounting. Derating applies above 25 °C ambient: power dissipation drops to 350 mW at 70 °C and 250 mW at 100 °C per datasheet Table 5. This rating assumes proper thermal layout with recommended 1 cm² copper pad for collector (pin 6).

Can the NPN RET (TR2) be used independently of the PNP BISS (TR1)?

Yes - TR1 and TR2 share only thermal coupling, not electrical connection. Their emitters (pins 1 and 4), bases (pins 2 and 5), and collectors (pins 6 and 3) are fully isolated. TR2 operates as a standalone resistor-equipped transistor with 50 V V_CEO, 100 mA I_O, and 1.9–2.5 V VI(on), usable in any logic-buffer or LED-driver role without engaging TR1.

What is the significance of the R2/R1 ratio specification?

The R2/R1 ratio (0.8–1.2, typ. 1.0) defines internal current-mirror precision in the RET section. It directly determines h_FE compensation stability: a 1.0 ratio ensures optimal base current mirroring for consistent saturation behavior across temperature and process variation, critical for reliable on-state performance in battery-powered systems.

Is PBLS2002D,115 RoHS-compliant and halogen-free?

Yes - PBLS2002D,115 meets RoHS Directive 2011/65/EU and is halogen-free per Nexperia standard specifications. The SOT457 package uses lead-free matte tin termination, and the device complies with JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/85 % RH.
