Product details
Overview
BC52-16PA,115 from Nexperia is a PNP medium-power surface-mount transistor in the SOT1061 (HUSON3) package, rated for −60 V VCEO, −1 A continuous collector current, and 1.10 W power dissipation on 6 cm² FR4 copper pad. It features hFE selection −16 (100–250 at VCE = −2 V, IC = −150 mA), AEC-Q101 qualification, and an exposed thermal pad for enhanced heat transfer. It serves as a high-side switch or linear regulator pass element in automotive body control modules.
For engineers reviewing the BC52-16PA,115 datasheet, BC52-16PA,115 pinout, BC52-16PA,115 application, or BC52-16PA,115 equivalent, this page delivers verified pin functions, thermal resistance values (Rth(j-sp) = 20 K/W), hFE binning details, and direct alternatives with documented electrical and packaging differences - all extracted from the official Nexperia Rev. 9 product data sheet.
Technical Context
This device operates as a silicon PNP bipolar junction transistor optimized for medium-power linear and switching applications. Its SOT1061 package integrates a thermally enhanced leadless structure with a 2.0 × 2.0 × 0.65 mm body and exposed collector terminal for low Rth(j-sp).
The −16 hFE selection ensures predictable DC gain stability across production lots under VCE = −2 V and IC = −150 mA conditions, supporting precise current mirror or amplifier biasing. AEC-Q101 qualification confirms suitability for automotive ambient temperature ranges (−55 °C to +150 °C) and reliability stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V - Maximum safe collector-emitter voltage with base open; defines breakdown margin in high-side switch configurations. |
| IC | −1 A - Continuous DC collector current rating; sets maximum load drive capability in linear regulators or MOSFET drivers. |
| hFE (−16 bin) | 100–250 at VCE = −2 V, IC = −150 mA - Tight DC current gain range enabling stable bias design without external trimming. |
| Ptot (6 cm² pad) | 1.10 W - Maximum power dissipation achievable with 6 cm² copper area on single-layer FR4; determines thermal footprint requirements. |
| Rth(j-sp) | 20 K/W - Junction-to-solder-point thermal resistance; quantifies heat transfer efficiency to PCB copper, critical for thermal management. |
| fT | 145 MHz - Transition frequency at VCE = −5 V, IC = −50 mA; supports moderate-speed switching up to ~10–20 MHz practical operation. |
| VCE(sat) | −0.5 V at IC = −500 mA, IB = −50 mA - Low saturation voltage minimizes conduction loss in high-side switch applications. |
Pinout & Package
SOT1061 (HUSON3) is a 3-terminal, leadless, ultra-thin plastic package measuring 2.0 × 2.0 × 0.65 mm with an exposed collector pad for thermal and electrical conduction. The package has no leads; terminals are soldered directly to PCB pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input for forward-active or saturation operation; requires current-limited drive to achieve target IC. |
| 2 | Emitter | Common reference node in common-base configuration; connected to higher potential rail in high-side switch topology. |
| 3 | Collector | Main current output terminal and thermal interface; electrically and thermally tied to exposed metal pad on underside of package. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards. |
| hFE selection −16 | Guaranteed 100–250 DC current gain at standardized test conditions, reducing binning variance in production assemblies. |
| Exposed collector pad | Enables direct thermal coupling to PCB copper; achieves Rth(j-sp) = 20 K/W and supports 1.10 W dissipation with 6 cm² pad. |
| Ultra-thin profile (0.65 mm max) | Enables space-constrained designs such as battery management PCBs and compact automotive ECUs where Z-height is critical. |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCX52-16,115 | SOT89 package (larger footprint, exposed die pad); Rth(j-a) = 93 K/W (6 cm² pad) vs. 114 K/W for BC52-16PA; same −60 V/−1 A ratings and hFE −16 bin. | Requires larger PCB area and different reflow footprint; better suited for manual assembly or lower-density layouts. | Select when thermal performance priority exceeds size constraints, or when SOT89 is already standardized in existing designs. |
| BCP52-16,115 | SOT223 package (4-pin, larger than SOT1061); Rth(j-a) = 93 K/W (6 cm² pad); identical electrical specs but higher mounting height (1.8 mm vs. 0.65 mm). | Not suitable for ultra-low-profile applications; offers higher mechanical robustness and easier visual inspection. | Choose when board-level shock/vibration resistance is critical, or when legacy SOT223 tooling and stencils are in place. |
Compared with BCX52-16,115 and BCP52-16,115, BC52-16PA,115 delivers the smallest Z-height and highest board-area efficiency, while trading slightly higher thermal resistance for extreme miniaturization - making it optimal for next-gen automotive modules where space is constrained but thermal budget remains adequate.

FAQ
What does the "−16" suffix indicate in BC52-16PA,115?
The "−16" denotes the hFE gain bin: guaranteed DC current gain of 100–250 at VCE = −2 V and IC = −150 mA. This binning enables consistent biasing in production without post-manufacture gain sorting or external compensation networks.
Can BC52-16PA,115 replace BCX52-16,115 in an existing SOT89 layout?
No - BC52-16PA uses the SOT1061 package (2.0 × 2.0 mm), which is physically incompatible with SOT89 footprints (4.6 × 2.6 mm). Pad geometry, thermal land pattern, and solder paste volume differ significantly; redesign of the PCB landing pattern is required.
What is the maximum allowable PCB copper area for thermal optimization?
The datasheet specifies performance up to 6 cm² of single-sided copper on FR4 for the SOT1061 package. With that area, Ptot reaches 1.10 W and Rth(j-a) improves to 114 K/W. Larger areas yield diminishing returns and are not characterized in the official data sheet.
Is reflow soldering mandatory for BC52-16PA,115?
Yes - Nexperia explicitly states "Reflow soldering is the only recommended soldering method" for SOT1061. Wave soldering is not supported due to thermal mass asymmetry and risk of solder joint voiding or package delamination.
