NXP Semiconductors PBSS5140V,315

Overview

PBSS5140V,315 from Nexperia is a 40 V PNP low V_CEsat transistor in SOT666 package, rated for −1 A DC collector current and −300 mW power dissipation at 25 °C ambient, with typical V_CEsat of −120 mV at I_C = −500 mA / I_B = −50 mA, used for high-efficiency supply line switching in battery-powered handheld devices.

For engineers reviewing the PBSS5140V,315 datasheet, PBSS5140V,315 pinout, PBSS5140V,315 application, or PBSS5140V,315 equivalent, key selection criteria include verified low on-resistance (<340 mΩ), ultra-thin 1.6 mm × 1.2 mm footprint, thermal resistance (410 K/W), collector-emitter voltage rating (−40 V), and compatibility with reflow soldering processes.

Technical Context

The PBSS5140V,315 is a discrete PNP bipolar junction transistor optimized for low-saturation-voltage switching. Its flat-lead SOT666 package improves thermal conduction and enables self-alignment during reflow soldering.

It delivers high DC current gain (h_FE = 300–800 at I_C = −100 mA) and high-frequency capability (f_T = 150 MHz), while maintaining tight V_CEsat control across load currents up to −1 A and operating junction temperatures up to 150 °C.

FAQ

What is the maximum continuous collector current rating for PBSS5140V,315?

The PBSS5140V,315 is rated for −1 A DC collector current under standard PCB conditions (single-side copper, tin-plated, standard footprint). At elevated ambient temperatures or with enhanced thermal pads (1 cm² collector pad), it supports higher transient currents but maintains −1 A as its specified continuous rating. This value is confirmed in the Limiting Values table of the official Nexperia datasheet.

Does PBSS5140V,315 support wave soldering?

No, PBSS5140V,315 is qualified for reflow soldering only, as explicitly stated in the Thermal Characteristics section of the datasheet. Wave soldering is not recommended due to thermal stress risks on the ultra-thin SOT666 package and potential damage to internal wire bonds. Reflow profiles must comply with JEDEC J-STD-020 standards.

What is the typical V_CEsat of PBSS5140V,315 at I_C = −500 mA?

The typical V_CEsat of PBSS5140V,315 is −120 mV at I_C = −500 mA and I_B = −50 mA, with a maximum of −170 mV under the same conditions. This value is measured at Tamb = 25 °C and is critical for calculating conduction losses in high-efficiency switching applications.

Is PBSS5140V,315 pin-compatible with its NPN complement PBSS4140V?

Yes, PBSS5140V,315 and PBSS4140V share identical SOT666 packaging and pin configuration (collector–collector–base–emitter–collector–collector), enabling direct layout reuse in complementary switching designs. However, polarity reversal requires corresponding changes to base drive polarity and signal logic.

What is the thermal resistance (R_{th j-a}) of PBSS5140V,315 on a standard PCB?

The thermal resistance from junction to ambient (R_{th j-a}) for PBSS5140V,315 is 410 K/W when mounted on a standard PCB (single-side copper, tin-plated, standard footprint). This value assumes no additional thermal vias or copper pour and defines the worst-case thermal performance for initial layout estimation.
