Nexperia USA Inc. PBSS4260PANP,115

Overview

PBSS4260PANP from Nexperia is a dual NPN/PNP low V_CE(sat) BISS transistor in a DFN2020-6 (SOT1118) package, rated for 60 V V_CEO, 2 A continuous collector current per transistor, and featuring 165 mΩ R_CE(sat) (NPN) and 250 mΩ R_CE(sat) (PNP) at I_C = ±1 A. It serves as a compact, thermally efficient load switch in battery-powered power management circuits.

For engineers reviewing the PBSS4260PANP datasheet, PBSS4260PANP pinout, PBSS4260PANP application, or PBSS4260PANP equivalent, this device supports high-efficiency switching in automotive-grade load control, motor/fan drivers, and bidirectional charging circuits where low conduction loss and AEC-Q101 qualification are required.

Technical Context

This dual-die discrete integrates complementary NPN and PNP BISS transistors on a single DFN2020-6 substrate, enabling independent high-side (PNP) and low-side (NPN) switching without external pairing. Each transistor delivers high h_FE (up to 85 for NPN, 75 for PNP at I_C = 2 A) and ultra-low saturation resistance under pulsed conditions (tp ≤ 300 µs).

Thermal performance is optimized via solder-point thermal resistance of 30 K/W and junction-to-ambient resistance as low as 63 K/W on 4-layer PCBs with 70 µm copper and extended collector pad - critical for sustained 2 A operation in space-constrained industrial and automotive modules.

Key Specifications

Pinout & Package

DFN2020-6 (SOT1118) is a leadless, thermally enhanced ultra-thin surface-mount package measuring 2.0 × 2.0 × 0.65 mm, with exposed die pad for improved heat transfer and six terminals arranged in a 2×3 grid.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual complementary BISS transistor applications.

Compared with PBSS4260PANP, PBSS4260PAN and PBSS5260PAP each provide only half the functional integration - requiring two separate devices and additional PCB area to replicate the single-package NPN+PNP switching capability, increasing BOM count and layout complexity.

FAQ

What is the maximum continuous current per transistor in PBSS4260PANP?

The PBSS4260PANP supports 2 A continuous collector current (I_C) for both the NPN (TR1) and PNP (TR2) transistors under T_amb ≤ 25 °C with appropriate PCB copper area. Derating applies above ambient temperature - e.g., 1.4 A at 85 °C ambient on a 4-layer board with 70 µm copper and 1 cm² collector pad.

How does the DFN2020-6 package improve thermal performance over traditional SOT packages?

The DFN2020-6 (SOT1118) package features an exposed thermal pad and optimized internal die attach, achieving R_th(j-sp) = 30 K/W - nearly 2× better than typical SOT23-6. This allows 2 W total dissipation on a 4-layer PCB, enabling higher current density without external heatsinking in compact designs.

Can PBSS4260PANP be used in H-bridge motor drivers?

Yes - its integrated NPN and PNP transistors can configure two legs of an H-bridge (e.g., one device for high-side PNP + low-side NPN). However, full H-bridge requires two PBSS4260PANP units (four transistors total) due to pinout constraints - it does not contain four fully independent switches in one package.

Is the AEC-Q101 qualification applicable to both transistors in the package?

Yes - the entire PBSS4260PANP device, including both TR1 (NPN) and TR2 (PNP), was qualified as a single unit per AEC-Q101 Rev D. Stress testing covered temperature cycling, humidity, HTOL, and ESD for the complete dual-die assembly, not individual dies.
