Product details
Overview
PBSS2515MB,315 from Nexperia is an AEC-Q101-qualified NPN low VCEsat Breakthrough In Small Signal (BISS) transistor in a leadless ultra-small SOT883B package (1.0 × 0.6 × 0.37 mm), rated for 15 V VCEO, 500 mA continuous IC, and 360–500 mΩ RCEsat at IC = 500 mA / IB = 50 mA. It serves as a high-efficiency switching element in space-constrained DC-DC converters and LED driver stages.
For engineers reviewing the PBSS2515MB,315 datasheet, PBSS2515MB,315 pinout, PBSS2515MB,315 application, or PBSS2515MB,315 equivalent, key selection criteria include its ultra-low saturation resistance, AEC-Q101 qualification for automotive environments, minimal PCB footprint, and thermal performance on FR4 with 212 K/W Rth(j-a) under optimized pad layout.
Technical Context
This BISS transistor employs a proprietary epitaxial structure to achieve significantly lower VCEsat and RCEsat versus standard small-signal NPNs-enabling higher efficiency in low-voltage switching applications where conduction loss dominates. Its fT of 250–420 MHz supports fast switching up to several hundred kHz without compromising gain stability.
The device operates across −55 °C to +150 °C junction temperature, with hFE maintained at ≥90 at IC = 500 mA and ≥150 at IC = 100 mA, ensuring robust current amplification under pulsed load conditions typical in battery charger and backlight dimming circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 15 V - Maximum allowable collector-emitter voltage before breakdown; sets upper limit for supply rail compatibility in 12 V automotive and portable systems. |
| IC (continuous) | 500 mA - Continuous collector current rating; defines steady-state load-handling capability in supply line switches and LED drivers. |
| RCEsat | 360–500 mΩ - On-resistance under saturation; directly determines power loss (P = I²R) and thermal rise in high-duty-cycle switching. |
| VCEsat | 25–250 mV - Saturation voltage at IC = 10–500 mA; enables sub-0.3 V drop for efficient operation in ≤3.3 V logic-controlled circuits. |
| fT | 250–420 MHz - Transition frequency; ensures sufficient gain-bandwidth for stable closed-loop control in high-frequency DC-DC feedback paths. |
| hFE | 90–200 - DC current gain across IC = 10–500 mA; supports reliable base drive design with low IB overhead in microcontroller-driven applications. |
| Package | SOT883B - Leadless 3-terminal surface-mount package (1.0 × 0.6 × 0.37 mm); reduces PCB area by >50% vs. SOT23 and eliminates lead inductance for cleaner switching edges. |
Pinout & Package
SOT883B is a leadless, ultra-thin plastic package with three solderable terminals on the bottom side. Its 0.37 mm height and 1.0 mm × 0.6 mm footprint enable placement in tight spaces such as wearable electronics and ultra-thin display modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input terminal; requires ~50 mA base current to fully saturate at 500 mA collector load-enables direct GPIO driving from 3.3 V MCUs without external level-shifting. |
| 2 | Emitter (E) | Current return path; internally connected to the thermal pad in standard mounting-must be routed to a large copper pour for optimal heat dissipation. |
| 3 | Collector (C) | High-current output terminal; designed for connection to load or power rail; thermal pad under collector improves Rth(j-a) to 212 K/W when mounted on 1 cm² FR4 copper. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD-supports use in infotainment power rails and body control modules without additional qualification effort. |
| Ultra-low RCEsat | 360 mΩ typical at 500 mA enables <100 mW conduction loss-reduces thermal stress and eliminates need for heatsinking in space-limited battery-powered devices. |
| 0.37 mm package height | Enables stacking under displays or behind connectors in slim-profile consumer electronics-critical for modern wearables and compact IoT sensors. |
| High fT & stable hFE | 420 MHz fT and hFE ≥90 at full rated current ensure predictable switching behavior and minimal gate-drive complexity in PWM-controlled loads. |
| Reduced PCB area | 1.0 × 0.6 mm footprint occupies <30% of SOT23 area-allows denser routing in multi-rail PMIC layouts and saves layer count in 2-layer portable PCBs. |
Applications
| DC-DC Conversion | Supply Line Switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low VCEsat NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004K-7 | 20 V VDS, MOSFET with 320 mΩ RDS(on); requires 4.5 V gate drive; no integrated base resistor. | Higher voltage margin but needs level-shifter for 3.3 V MCU control; less suitable for ultra-low-voltage (<2.5 V) bias rails. | Select when higher blocking voltage or zero-gate-threshold operation is required; avoid if board space or 3.3 V direct drive is critical. |
| PBSS2515PA,115 | Same die in larger SOT323 package (2.1 × 1.25 × 0.95 mm); identical electrical specs but 2.6× larger footprint and 2.6× higher Rth(j-a). | Compatible for prototyping or legacy layouts but sacrifices PCB density and thermal performance in production designs. | Select only for hand-soldering feasibility or compatibility with existing SOT323 footprints; not recommended for volume automotive or portable designs. |
Compared with DMN2004K-7 and PBSS2515PA,115, PBSS2515MB,315 uniquely delivers AEC-Q101 compliance, 0.37 mm height, and 360 mΩ RCEsat in the smallest possible footprint-making it the optimal choice for space- and thermal-constrained automotive and portable power switches.

FAQ
What is the maximum continuous collector current for PBSS2515MB,315?
The maximum continuous collector current (IC) is 500 mA at Tamb ≤ 25 °C with proper PCB thermal management. At elevated ambient temperatures or reduced copper area, derating applies per the thermal resistance curve-e.g., 350 mA at 85 °C ambient with standard FR4 footprint.
Is PBSS2515MB,315 suitable for automotive applications?
Yes-PBSS2515MB,315 is AEC-Q101 qualified and tested for automotive stress conditions including temperature cycling, high-temperature reverse bias, and ESD. It is approved for use in non-safety-critical automotive subsystems such as infotainment power supplies and body electronics.
How does the SOT883B package affect thermal performance?
The SOT883B package achieves Rth(j-a) = 212 K/W when mounted on 1 cm² collector pad on FR4, versus 500 K/W on standard footprint. This 58% improvement enables 2.8× higher power dissipation before reaching 150 °C junction temperature-critical for sustained 500 mA operation.
Can PBSS2515MB,315 replace a standard SOT23 NPN transistor?
Electrically yes-but only if the PCB layout accommodates the smaller SOT883B footprint and reflow profile. Its lower VCEsat and RCEsat improve efficiency, yet the absence of leads requires precise stencil design and AOI inspection; mechanical replacement without layout revision is not feasible.
