Nexperia USA Inc. PBLS2022D,115

Overview

PBLS2022D from Nexperia is a dual-function SOT457 (SC-74) surface-mount 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 as low as 78 mΩ at −1.8 A and integrated bias resistors (R1 = 4.7 kΩ, R2/R1 = 1). It serves as a space-saving high-side load switch in battery-powered LED backlighting and portable equipment.

For engineers reviewing the PBLS2022D datasheet, PBLS2022D pinout, PBLS2022D application, or PBLS2022D equivalent, this dual-transistor solution enables compact supply-line switching with low conduction loss, AEC-Q101 qualification for automotive-grade reliability, and integrated biasing to eliminate external resistors in RET-based control stages.

Technical Context

The PBLS2022D integrates two functionally independent transistors on one die: TR1 is a PNP BISS device optimized for high-current, low-saturation switching with V_CEsat down to −140 mV at −1.8 A/−100 mA drive; TR2 is an NPN RET with built-in 4.7 kΩ input resistor (R1) and unity R2/R1 ratio, enabling direct logic-level interface without external bias components.

TR1 operates as a high-side switch with −20 V blocking capability and 150 °C junction rating, while TR2 functions as a driver or level-shifting stage with VI(on) = 1.9 V (typ) and VI(off) = 1.1 V (typ), supporting robust noise-immune digital control in mixed-voltage systems.

FAQ

What is the maximum continuous current PBLS2022D can switch on its PNP BISS transistor?

The PBLS2022D's TR1 PNP BISS transistor supports −1.8 A continuous collector current at T_amb ≤ 25 °C with standard FR4 PCB mounting. Derating applies above 25 °C per the 260 K/W R_th(j-a); at 85 °C ambient, max continuous current drops to approximately −1.2 A to maintain T_j ≤ 150 °C.

Can PBLS2022D be used with 3.3 V logic to drive the NPN RET section?

Yes - the TR2 NPN RET has VI(on) = 1.9 V (typ) and VI(off) = 1.1 V (typ), providing 0.8 V noise margin against 3.3 V logic high/low levels. With R1 = 4.7 kΩ, a 3.3 V input delivers ~0.7 mA base current, sufficient to saturate TR2 at up to 100 mA output.

Does PBLS2022D require external pull-up or pull-down resistors on any pins?

No external bias resistors are required for TR2 due to its integrated R1 and R2. Pin 2 (TR2 input) is internally biased; pins 3 and 4 form an open-collector output pair. TR1's base (pin 1) must be actively driven negative to turn on - no pull-up/pull-down needed if controlled by a dedicated driver stage.

How does the AEC-Q101 qualification impact PBLS2022D's suitability for industrial applications?

AEC-Q101 qualification subjects PBLS2022D to accelerated stress tests including HTGB, TC, and HTRB far exceeding standard industrial requirements. Its 150 °C T_j rating, −55 °C to +150 °C T_amb range, and validated reliability make it appropriate for harsh industrial environments - such as factory automation controllers - where extended temperature operation and long-term stability are mandatory.
