Product details
Overview
BC52PA,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 AEC-Q101 qualified for automotive use. It delivers high thermal performance via exposed collector terminal, supports three hFE gain selections (63–250), and serves in linear voltage regulators and MOSFET drivers where compact size and robust power handling are required.
For engineers reviewing the BC52PA,115 datasheet, BC52PA,115 pinout, BC52PA,115 application, or BC52PA,115 equivalent, this page provides verified pin configuration, thermal resistance data (Rth(j-sp) = 20 K/W), hFE selection codes (BS/BT/BU), AEC-Q101 qualification status, and direct comparison with BCX52 (SOT89) and BCP52 (SOT223) alternatives.
Technical Context
This device operates as a medium-power PNP bipolar junction transistor optimized for linear regulation and switching in space-constrained automotive and industrial power management circuits. Its SOT1061 package integrates an exposed collector pad for low Rth(j-sp) (20 K/W) and enhanced electrical conductivity, enabling stable operation at Tj up to 150 °C.
It features three factory-selected DC current gain bins (hFE = 63–160 for -10 suffix, 100–250 for -16 suffix), specified at VCE = −2 V and IC = −150 mA. The −5 V VEBO rating and −100 nA IEBO support reliable biasing in high-side switch configurations with minimal leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V - Maximum safe collector-emitter voltage under open-base condition; enables use in 48 V automotive systems with margin. |
| IC | −1 A - Continuous DC collector current; supports medium-power load switching without forced cooling on standard FR4 PCB. |
| hFE (typ) | 63–250 - Factory-binned DC current gain; allows precise bias design across operating points (e.g., −150 mA @ −2 V). |
| Ptot (max) | 1.10 W - Total power dissipation at Tamb ≤25 °C with 6 cm² collector pad; defines thermal design envelope for PCB layout. |
| Rth(j-sp) | 20 K/W - Junction-to-solder-point thermal resistance; enables accurate transient thermal modeling for pulse-load reliability. |
| VCE(sat) | −0.5 V @ IC = −500 mA, IB = −50 mA - Low saturation voltage reduces conduction loss in high-side switch applications. |
| fT | 145 MHz - Transition frequency; supports stable operation in audio-frequency amplifiers and fast-switching control loops. |
Pinout & Package
SOT1061 (HUSON3) is a leadless, ultra-thin 2 mm × 2 mm × 0.65 mm plastic package with exposed collector terminal for thermal and electrical performance. The package has no leads - terminals are soldered directly to PCB pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input; requires current-limited drive (IB ≤ −0.3 A) to avoid damage during switching transients. |
| 2 | Emitter | Reference node for PNP operation; connected to higher potential rail (e.g., battery +) in high-side switch topologies. |
| 3 | Collector | Power output node; electrically and thermally tied to exposed copper pad on PCB for low-impedance path and heat extraction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
| Three hFE selections | Marking codes BS (-10), BT (-10PA), BU (-16PA) enable consistent gain matching across production batches for precision bias networks. |
| Exposed collector pad | Enables Rth(j-sp) = 20 K/W and Rth(j-a) = 76 K/W (4-layer PCB, 1 cm² pad), reducing thermal derating in compact designs. |
| Ultra-thin profile | 0.65 mm max height supports low-profile assemblies in space-critical modules such as battery management ICs and LED drivers. |
| High fT and low Cc | 145 MHz fT and 15 pF collector capacitance ensure stable small-signal amplification and fast switching with minimal ringing. |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|

IC Role / Device Role / Timing Role: Pass transistor controlling output voltage via feedback loop; operates in active region with constant VCE ≈ −2 V. Use Value: Low VCE(sat) (−0.5 V) minimizes dropout and power loss; AEC-Q101 rating ensures functional safety compliance. |
Use Scenario: Load switch enabling/disabling 12 V power to telematics module during vehicle sleep mode. IC Role / Device Role / Timing Role: High-side PNP switch controlled by microcontroller GPIO; emitter tied to battery, collector to load. Use Value: −1 A IC rating supports peak inrush currents; exposed collector pad maintains Tj < 125 °C during 100 ms turn-on pulses. |

IC Role / Device Role / Timing Role: Reverse-polarity protection and load disconnect switch; placed between battery and PMIC input. Use Value: −60 V VCEO accommodates load-dump transients; −5 V VEBO prevents base-emitter breakdown during hot-plug events. |
Use Scenario: Level-shifting driver stage for N-channel high-side MOSFET in BLDC motor gate driver. IC Role / Device Role / Timing Role: Active pull-down transistor sinking gate charge during MOSFET turn-off; base driven by logic-level signal. Use Value: 145 MHz fT ensures fast gate discharge (toff < 100 ns); low Cc avoids Miller-induced oscillation. |
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 |
|---|---|---|---|
| BCX52,115 | SOT89 package (larger footprint, exposed die pad), Rth(j-sp) = 16 K/W, same VCEO/IC ratings but lower Ptot (0.95 W @ 1 cm² pad). | Better thermal performance on minimal copper area; less suitable for ultra-thin assemblies due to 1.8 mm height. | Select when board space allows larger package and thermal pad area is limited to 1 cm². |
| BCP52,115 | SOT223 package (4-pin, larger body), higher Ptot (1.00 W @ 1 cm² pad), same gain bins and AEC-Q101 qualification. | Higher power handling and mechanical robustness; requires more PCB area and cannot fit in <1 mm height constraints. | Select when >1 W continuous dissipation is needed and Z-height >0.9 mm is acceptable. |
Compared with BCX52 and BCP52, BC52PA offers the smallest footprint and lowest profile while maintaining AEC-Q101 compliance and −1 A capability - making it optimal for next-generation automotive ECUs where board area and stack height are constrained.

FAQ
What is the marking code for BC52PA,115?
The BC52PA,115 uses the marking code "BS" for the hFE selection −10 (63–160), "BT" for −10PA, and "BU" for −16PA (100–250). These laser-marked identifiers appear on the top surface of the SOT1061 package and correspond directly to the 12NC ordering suffix.
Is BC52PA,115 suitable for high-frequency switching above 10 MHz?
Yes - with a typical fT of 145 MHz and low collector capacitance (15 pF), BC52PA,115 supports clean switching up to ~10–20 MHz in gate-driving and signal-amplification roles. Its performance remains stable under IC ≤ −500 mA and VCE ≥ −5 V conditions per datasheet characterization.
How does the SOT1061 package affect PCB layout requirements?
The SOT1061 requires a dedicated thermal pad (2.1 mm × 1.9 mm minimum) connected to a solid copper pour for the collector terminal. Reflow footprint dimensions are precisely defined: 0.55 mm × 1.05 mm solder lands with 0.25 mm stencil aperture - deviation risks solder voiding and thermal degradation.
Can BC52PA,115 replace BCX52 in existing designs?
Direct replacement is possible only with layout revision: BC52PA uses SOT1061 (2×2 mm, 0.65 mm height), while BCX52 uses SOT89 (4.6×2.6 mm, 1.8 mm height). Pinout differs (BC52PA: 1=base, 2=emitter, 3=collector; BCX52: 1=emitter, 2=collector, 3=base), requiring netlist and footprint updates.
