Product details

Overview

BCX52-10,115 from Nexperia is a PNP medium-power surface-mount transistor in SOT89 (SC-62) package, rated for −60 V V_CEO, −1 A continuous collector current, and 0.50 W power dissipation on standard FR4 PCB. It features h_FE = 63–160 at I_C = −150 mA, V_CE = −2 V, and is AEC-Q101 qualified for automotive linear voltage regulators and high-side switches.

For engineers reviewing the BCX52-115 datasheet, BCX52-10,115 pinout, BCX52-10,115 application, or BCX52-10,115 equivalent, this device serves as a thermally robust, medium-current PNP switch with exposed heatsink pad, precise h_FE binning (−10 grade), and validated performance in battery-driven power management circuits.

Technical Context

This PNP bipolar junction transistor operates in linear and switching modes with fixed emitter-base and collector-emitter polarity. Its SOT89 package integrates an exposed collector pad for direct thermal coupling to PCB copper, enabling stable operation up to 150 °C junction temperature under defined mounting conditions.

The −10 h_FE selection guarantees DC current gain between 63 and 160 at −150 mA collector current and −2 V V_CE, supporting predictable biasing in regulator error amplifiers and MOSFET gate drivers where gain consistency reduces loop compensation complexity.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V - Maximum safe collector-emitter voltage with base open; defines breakdown margin in high-side switch applications.
I_C	−1 A - Continuous DC collector current rating; supports medium-power load switching in battery management systems.
h_FE (−10)	63–160 - Guaranteed DC current gain range at −150 mA and −2 V; enables accurate current mirror or amplifier design without gain trimming.
P_tot (std FR4)	0.50 W - Total power dissipation on single-layer FR4 with standard footprint; sets thermal derating baseline for layout planning.
R_th(j-a)	250 K/W - Junction-to-ambient thermal resistance on standard FR4; informs minimum copper area needed for ambient temperature limits.
V_CE(sat)	−0.5 V max at −500 mA / −50 mA - Low saturation voltage minimizes conduction loss in linear regulators and active clamping circuits.
f_T	145 MHz - Transition frequency at −50 mA and −5 V; confirms suitability for audio-frequency amplification and fast-switching control loops.

Pinout & Package

SOT89 (SC-62/TO-243) plastic surface-mounted package with exposed die pad for thermal and electrical conductivity; 3-terminal leadless outline measuring 4.6 × 4.4 × 1.8 mm.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current exit node; connected to higher potential rail in high-side configurations; requires low-impedance return path.
2	Collector	Main current sink node; tied to exposed pad for thermal conduction and low-inductance grounding in power stages.
3	Base	Control input; driven with negative current relative to emitter to turn on; requires current-limiting resistor in discrete bias networks.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per JESD22 standards.
Exposed collector pad	Direct thermal interface to PCB copper; reduces R_th(j-sp) to 16 K/W and enables 0.95 W dissipation with 1 cm² mounting pad.
Three h_FE selections	−10 (63–160), −16 (100–250), and unmarked variants allow gain-matched pairs or optimized loop stability in feedback circuits.
High power capability	1.35 W max dissipation achievable with 6 cm² collector pad on FR4; supports compact designs without external heatsinks.
Low V_BE	−1.0 V max at −500 mA; reduces base drive power and improves efficiency in high-current switching applications.

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
BCX55,115	NPN complement; same SOT89 package, +60 V V_CEO, +1 A I_C, matched h_FE bins.	Requires inverted control logic and reversed PCB layout; used in low-side switching or complementary push-pull stages.	Select when NPN topology is required for ground-referenced loads or complementary pair design.
ZTX788B	Higher V_CEO (−80 V), lower h_FE (20–100), TO-92 package; no AEC-Q101 qualification.	Limited to non-automotive industrial use; lacks exposed thermal pad, requiring larger copper area for equivalent thermal performance.	Choose only for cost-sensitive non-automotive applications where −80 V rating is essential and thermal constraints permit TO-92 mounting.

Compared with BCX52-10,115, BCX55,115 offers complementary NPN functionality in identical packaging but demands revised biasing, while ZTX788B trades automotive qualification and thermal efficiency for higher voltage rating and through-hole compatibility.

FAQ

What is the difference between BCX52-10,115 and BCX52-16,115?

The suffix "-10" and "-16" denote different h_FE gain bins: BCX52-10 guarantees h_FE = 63–160 at I_C = −150 mA and V_CE = −2 V, while BCX52-16 guarantees h_FE = 100–250 under identical conditions. Both share identical package, voltage, current, and thermal ratings, allowing direct substitution where gain tolerance permits.

Can BCX52-10,115 be used in place of BCX52-10?

Yes - the ",115" suffix indicates the tape-and-reel packing method (8 mm pitch, 12 mm reel, T1 orientation) per Nexperia's ordering code system. BCX52-10 and BCX52-10,115 are electrically and mechanically identical; the comma notation specifies packaging only, not functional differentiation.

Is the exposed pad on the SOT89 package electrically connected to any terminal?

Yes - the exposed collector pad in the SOT89 package is internally connected to Pin 2 (collector). It must be soldered to a dedicated PCB copper pour tied to the collector net to achieve specified thermal resistance (R_th(j-sp) = 16 K/W) and power dissipation performance.

Does BCX52-10,115 require derating above 25 °C ambient?

Yes - its power dissipation must be linearly derated above 25 °C ambient. On standard FR4, P_tot decreases from 0.50 W at 25 °C to zero at 150 °C, following a slope of −5.0 mW/°C. Layouts using 1 cm² collector pad extend usable ambient range to 105 °C at full 0.95 W rating.
