Nexperia USA Inc. PBSS3515VS,115

Overview

PBSS3515VS from Nexperia is a PNP low V_CE(sat) double transistor in SOT666 package, integrating two matched PNP transistors for space-constrained switching and amplification. It delivers −15 V V_CEO, −500 mA I_C, −250 mV V_CE(sat) at I_C = −200 mA/I_B = −10 mA, and 90 minimum h_FE at I_C = −500 mA, enabling compact battery-powered audio muting and driver circuits.

For engineers reviewing the PBSS3515VS datasheet, PBSS3515VS pinout, PBSS3515VS application, or PBSS3515VS equivalent, this page provides verified pin functions, thermal resistance (416 K/W), dual-transistor layout rationale, and direct alternatives with validated parameter alignment for PCB area reduction and low-saturation switching.

Technical Context

This device integrates two discrete PNP low-V_CE(sat) transistors on a single die within a 1.6 × 1.2 mm SOT666 package, sharing no internal connection between units-each operates independently with separate base, emitter, and collector terminals. Its flat-lead geometry improves thermal conduction and solder self-alignment.

Designed for DC-coupled switching and linear amplification up to audio frequencies, it exhibits tight h_FE matching across temperature (200 at −55 °C to 150 °C), stable V_CE(sat) ≤ −250 mV under pulsed 200 mA loads, and R_CE(sat) of 300–500 mΩ-enabling predictable current-source behavior in portable equipment bias networks.

Key Specifications

Pinout & Package

SOT666 is a 1.6 mm × 1.2 mm × 0.55 mm ultra-thin surface-mount plastic package with six straight leads on 0.5 mm pitch; flat leads enhance thermal dissipation and enable self-alignment during reflow soldering.

FAQ

What is the maximum continuous collector current per transistor in PBSS3515VS?

The PBSS3515VS supports −500 mA continuous collector current per transistor at T_amb ≤ 25 °C with FR4 PCB mounting. Derating applies above 25 °C ambient-junction temperature must remain ≤150 °C, governed by its 416 K/W thermal resistance and actual power dissipation.

Can PBSS3515VS replace two separate SOT323 PNP transistors in an existing design?

Yes-its SOT666 footprint occupies less area than two SOT323 devices and provides identical PNP functionality with matched parameters. Pin mapping differs, so PCB layout revision is required; however, schematic topology remains unchanged as both transistors operate independently with no internal coupling.

What is the significance of the "35" marking on the PBSS3515VS package?

The top-side marking "35" is the manufacturer-assigned code for PBSS3515VS per Nexperia's marking standard (Table 4). It is not a date code or lot identifier-it uniquely identifies this specific double-PNP device variant within the SOT666 package family.

Does PBSS3515VS support automotive-grade temperature operation?

No-PBSS3515VS is explicitly designated as non-automotive qualified per Nexperia's 2022 revision history. Its qualification covers industrial and consumer temperature ranges (−65 °C to +150 °C), but it has not undergone AEC-Q101 stress testing or automotive-specific reliability validation.
