Product details
Overview
PBSS5140U,115 from Nexperia is a 40 V PNP low VCE(sat) transistor in SOT323 (SC-70) package, rated for −1 A DC collector current and −2 A peak current, with typical RCE(sat) of 300 mΩ at IC = −500 mA / IB = −50 mA. It serves as a high-efficiency switching element in battery-powered portable electronics requiring minimal conduction loss and thermal stress.
For engineers reviewing the PBSS5140U,115 datasheet, PBSS5140U,115 pinout, PBSS5140U,115 application, or PBSS5140U,115 equivalent, key selection criteria include verified low saturation voltage under high-current drive, thermal resistance (357 K/W with 1 cm² collector pad), and guaranteed hFE ≥ 160 at IC = −1 A - critical for reliable base-drive design in compact load-switching circuits.
Technical Context
This PNP transistor employs epitaxial planar die construction optimized for low on-resistance and fast switching in low-voltage DC applications. Its −40 V VCEO rating and −5 V VEBO support robust operation across wide supply ranges in portable systems.
Designed for DC switching-not linear amplification-it delivers stable VCE(sat) ≤ −500 mV at IC = −1 A / IB = −100 mA, with fT = 150 MHz enabling moderate-speed digital control without oscillation risk in properly decoupled layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V: Maximum safe collector-emitter blocking voltage in open-base configuration. |
| IC (DC) | −1 A: Continuous collector current capability without derating at Tamb ≤ 25 °C with standard PCB footprint. |
| RCE(sat) | <500 mΩ (typ. 300 mΩ): Equivalent on-resistance at IC = −500 mA / IB = −50 mA-directly determines power loss in switched loads. |
| hFE | 160–800: DC current gain range across operating conditions-enables predictable base drive sizing for target load currents. |
| VBE(sat) | −1.1 V (max): Base-emitter saturation voltage at IC = −1 A / IB = −50 mA-defines minimum driver voltage headroom required. |
| fT | 150 MHz: Transition frequency at IC = −50 mA / VCE = −10 V-supports clean edge transitions up to ~10–20 MHz switching. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 1.35 mm × 1.75 mm footprint, 0.65 mm pitch, 0.9 mm height, with exposed collector pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input; requires −100 mA max peak drive for full saturation at IC = −1 A. |
| 2 | Emitter | Common reference node; connected to higher potential rail in PNP high-side switch configurations. |
| 3 | Collector | Switched output terminal; thermally coupled to PCB copper for dissipation up to 350 mW with 1 cm² pad. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | ≤ −500 mV at IC = −1 A ensures <0.5 W conduction loss-critical for thermal management in sealed handheld enclosures. |
| High current capability | −2 A peak rating supports surge-tolerant operation during inrush or fault transients in battery-fed circuits. |
| Enhanced reliability | Reduced heat generation extends lifetime in continuous-duty switching applications like LCD backlight dimming drivers. |
| SC-70 compatibility | Replaces legacy SOT23-3 PNP transistors without layout redesign-pin-to-pin compatible with same footprint constraints. |
Applications
| General Purpose Switching | LCD Back Lighting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3005LKQ-7 | −30 V VCEO, −1.2 A IC, SOT23 package, RCE(sat) = 350 mΩ @ −500 mA | Lower voltage rating limits use in 36 V automotive or industrial rails | Select when board space allows SOT23 and system VCC ≤ 24 V. |
| BC807-40,115 | −45 V VCEO, −500 mA IC, SOT323, hFE = 250–630, RCE(sat) = 500 mΩ @ −100 mA | Lower current capability and higher saturation voltage reduce efficiency in >300 mA loads | Choose for cost-sensitive designs where peak load ≤ 300 mA and thermal margin is ample. |
Compared with DMT3005LKQ-7 and BC807-40,115, PBSS5140U,115 uniquely balances −40 V rating, −1 A DC current, and sub-500 mΩ RCE(sat) in SC-70-making it optimal for thermally constrained, medium-current portable switching where voltage headroom and efficiency are jointly critical.

FAQ
What is the maximum allowable base current for PBSS5140U,115?
The absolute maximum peak base current (IBM) is −1 A per the datasheet limiting values table. However, for reliable saturation at IC = −1 A, the recommended drive is −100 mA (IC/IB = 10), ensuring VCE(sat) ≤ −500 mV without excessive base power dissipation or thermal stress on the bond wires.
Can PBSS5140U,115 be used in linear amplifier applications?
No-PBSS5140U,115 is characterized and qualified exclusively for switching operation. Its hFE variation across IC and temperature, lack of linearity specifications (e.g., distortion, output impedance), and thermal design optimized for pulsed dissipation make it unsuitable for analog amplification.
Is the SOT323 package lead-free and RoHS compliant?
Yes-PBSS5140U,115 is manufactured in a lead-free, RoHS-compliant SOT323 package per Nexperia's standard qualification. The device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and is compatible with standard reflow profiles including Pb-free soldering at peak temperatures up to 260 °C.
How does thermal performance change with PCB copper area?
Rth j-a improves from 500 K/W (standard footprint) to 357 K/W when a 1 cm² copper pad is connected to the collector terminal. This 29% reduction in thermal resistance directly increases allowable continuous power dissipation from 250 mW to 350 mW at Tamb = 25 °C, enabling higher sustained load currents without junction overheating.
