Product details

Overview

BC52-10PA,115 from Nexperia is a PNP medium-power surface-mount transistor in SOT1061 (HUSON3) package, rated for −60 V V_CEO, −1 A continuous collector current, and AEC-Q101 qualified for automotive use. It features h_FE = 63–160 at I_C = −150 mA, V_CE(sat) ≤ −0.5 V at I_C = −500 mA/I_B = −50 mA, and thermal resistance R_th(j-sp) = 20 K/W - enabling high-side switching and linear regulation in space-constrained battery-powered systems.

For engineers reviewing the BC52-10PA,115 datasheet, BC52-10PA,115 pinout, BC52-10PA,115 application, or BC52-10PA,115 equivalent, this page delivers verified electrical specs, validated SOT1061 terminal mapping, real-world use cases in power management and MOSFET driving, and confirmed AEC-Q101 qualification status - all grounded in Nexperia's Rev. 9 product data sheet (2011).

Technical Context

This device operates as a medium-power PNP bipolar junction transistor optimized for linear voltage regulation and high-side switch configurations where emitter-follower or common-emitter topologies demand stable DC gain and low saturation voltage. Its SOT1061 package integrates an exposed thermal pad for direct PCB heat sinking, supporting up to 1.10 W total power dissipation under 6 cm² copper mounting.

The −10 suffix denotes h_FE selection of 63–160 at V_CE = −2 V and I_C = −150 mA, distinguishing it from the −16 variant (100–250). It exhibits f_T = 145 MHz and C_c = 15 pF, confirming suitability for moderate-speed switching and analog amplification below 100 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V - Maximum safe collector-emitter blocking voltage in open-base configuration; enables use in 48 V automotive and industrial supply rails.
I_C	−1 A - Continuous DC collector current rating; supports load switching up to ~1 A with appropriate heatsinking.
h_FE (−10)	63–160 at V_CE = −2 V, I_C = −150 mA - Tight DC current gain bin ensures predictable base drive requirements in linear regulators and driver stages.
V_CE(sat)	≤ −0.5 V at I_C = −500 mA / I_B = −50 mA - Low saturation voltage minimizes conduction loss in high-side switch applications.
R_th(j-sp)	20 K/W - Junction-to-solder-point thermal resistance; enables efficient heat transfer to PCB copper, critical for sustained 0.83 W operation on 1 cm² pad.
f_T	145 MHz - Transition frequency confirms usable bandwidth for fast-switching control loops and signal amplification up to ~100 MHz.
AEC-Q101	Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard.

Pinout & Package

SOT1061 (HUSON3) is a leadless, ultra-thin 3-terminal plastic package (2.0 × 2.0 × 0.65 mm) with exposed thermal pad on underside for enhanced thermal and electrical conductivity. The body provides mechanical robustness and solder joint reliability in automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node; requires current-limited drive (I_B ≤ −0.3 A) to achieve full conduction without thermal runaway.
2	Emiter	High-side reference node; connects to positive rail in emitter-follower configuration or load return in common-emitter switch.
3	Collector	Power output node; electrically and thermally connected to exposed pad - must be soldered to ≥1 cm² copper pour for rated power handling.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive underhood environments (−40 °C to +150 °C ambient), including HTSL, TC, and AC/DC life testing.
Three h_FE selections	−10 (63–160) and −16 (100–250) bins enable precise base drive optimization across production lots and design margins.
Exposed thermal pad (SOT1061)	Enables R_th(j-a) = 114 K/W (6 cm² copper) - 3× better than standard SOT23, supporting higher continuous power in compact layouts.
Low V_CE(sat)	≤ −0.5 V at I_C = −500 mA reduces conduction loss by >30% vs. legacy PNP transistors, improving efficiency in linear regulators.
High f_T (145 MHz)	Supports stable feedback loop compensation in adjustable LDOs and fast turn-off in MOSFET gate drivers without added snubbing.

Applications

IC Role / Device Role / Timing Role: PNP-based totem-pole or complementary pair providing fast sink/source capability.

Use Value: 145 MHz f_T ensures <100 ns switching transitions; low C_c (15 pF) prevents Miller-induced shoot-through.

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
BCX52-10,115 (SOT89)	Same h_FE bin (63–160) and V_CEO/I_C ratings, but larger SOT89 package with higher P_tot (0.95 W on 1 cm²) and R_th(j-sp) = 16 K/W.	Preferred where higher power margin or wave-solder compatibility is required; not suitable for ultra-dense layouts.	Select when thermal headroom >0.1 W is needed or existing SOT89 footprint reuse is prioritized over size reduction.
BCP52-10,115 (SOT223)	Identical electrical specs and h_FE bin, but SOT223 offers 4-pin layout (dual collector) and 1.00 W P_tot on 1 cm² copper.	Used in higher-current linear regulators (>700 mA) or where dual collector routing simplifies PCB layout.	Choose when board space permits larger footprint and dual-collector routing improves thermal symmetry or current sharing.

Compared with BCX52-10,115 and BCP52-10,115, BC52-10PA,115 delivers the smallest footprint (2×2 mm) and lowest profile (0.65 mm), trading 0.12–0.17 W absolute power headroom for maximum PCB area savings in portable and automotive ECUs.

FAQ

What is the maximum allowable base current for BC52-10PA,115?

The absolute maximum DC base current is −0.3 A, and peak pulse current is also limited to −0.3 A for t_p ≤ 1 ms. Exceeding this risks metallization failure or bond wire damage. For reliable operation at I_C = −500 mA, typical I_B = −50 mA is used - well within safe limits and ensuring h_FE-driven saturation.

Is BC52-10PA,115 compatible with lead-free reflow soldering profiles?

Yes - BC52-10PA,115 is qualified for standard IPC/JEDEC J-STD-020D lead-free reflow, with peak temperature up to 260 °C. The SOT1061 package uses matte tin terminations and is specified for reflow only (wave soldering not recommended). Footprint dimensions and solder paste stencil design are provided in Figure 26 of the datasheet.

How does the h_FE selection −10 differ from −16 in practical circuit design?

The −10 variant has h_FE = 63–160 at I_C = −150 mA, while −16 is 100–250. In linear regulators, −10 allows more conservative base resistor sizing for worst-case gain, reducing sensitivity to temperature drift. In switching applications, −16 enables lower base drive current but demands tighter tolerance on base bias networks to avoid overdrive.

Can BC52-10PA,115 replace BC807-25 in a 5 V logic-level high-side switch?

No - BC807-25 is an SOT323 NPN transistor (V_CEO = 45 V, I_C = −0.5 A), while BC52-10PA,115 is a PNP with −60 V/−1 A rating and different pinout (base-emitter-collector vs. emitter-base-collector). Direct replacement would invert logic polarity and exceed package thermal limits; redesign of drive topology and layout is required.
