Product details

Overview

BCP52-10,135 from Nexperia is a PNP medium-power bipolar junction transistor in SOT223 (SC-73) surface-mount package, rated for −60 V V_CEO, −1 A continuous collector current, and 0.65 W power dissipation on standard FR4 PCB. It features h_FE = 63–160 at I_C = −150 mA / V_CE = −2 V (−10 gain selection), AEC-Q101 qualification, and exposed collector pad for thermal and electrical conduction-used in linear voltage regulators and high-side switches.

For engineers reviewing the BCP52-10,135 datasheet, BCP52-10,135 pinout, BCP52-10,135 application, or BCP52-10,135 equivalent, this page delivers verified specifications, validated SOT223 pin mapping, automotive-grade thermal performance data, and direct alternatives for PNP medium-power switching and amplification in battery-driven and power management circuits.

Technical Context

This PNP transistor operates in active, saturation, and cutoff regions with defined DC current gain (h_FE) across three selections (−10, −16, and standard), enabling precise biasing in linear regulator error amplifiers and MOSFET gate drivers. Its −0.5 V V_CE(sat) at I_C = −500 mA / I_B = −50 mA supports low-loss high-side switching.

The SOT223 package integrates an exposed collector pad (Pin 2 and Pin 4) that serves as both primary current path and thermal interface-reducing R_th(j-a) to 93 K/W with 6 cm² copper pad-making it suitable for thermally constrained PCB layouts in automotive and industrial power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum safe collector-emitter voltage under open-base condition; enables use in 48 V automotive systems and industrial 24–48 V rails.
I_C	−1 A continuous: Rated DC collector current; supports medium-power load switching up to ~12 W at 12 V with proper heatsinking.
h_FE (−10 selection)	63–160 at V_CE = −2 V, I_C = −150 mA: Tighter DC gain band improves consistency in feedback loops of linear regulators and current sources.
V_CE(sat)	−0.5 V max at I_C = −500 mA / I_B = −50 mA: Low saturation voltage minimizes conduction loss in high-side switch configurations.
P_tot	0.65 W on standard FR4 (1-layer, 25 °C ambient): Power handling capacity defines maximum steady-state dissipation without forced cooling.
R_th(j-a)	93 K/W with 6 cm² collector pad: Thermal resistance directly determines junction temperature rise-e.g., +56 °C rise at 0.6 W dissipation.
AEC-Q101 qualified	Validated for automotive applications per stress test requirements; ensures reliability in under-hood and infotainment power stages.

Pinout & Package

SOT223 (SC-73) plastic surface-mounted package with 4 leads and exposed collector pad for enhanced thermal and electrical conductivity. Dimensions: 6.7 × 3.7 × 1.8 mm (L × W × H); body thickness 1.5 mm; lead pitch 1.5 mm.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on.
2	Collector	Main current-carrying terminal; electrically and thermally connected to exposed metal pad-must be soldered to large copper area.
3	Emitter	Reference terminal for current flow; typically tied to higher potential rail in high-side switch configuration.
4	Collector	Second collector connection-internally bonded to Pin 2; used to increase current capacity and improve thermal spreading.

Key Features

Feature	Design Value
Three h_FE selections	Enables precise gain matching across production batches-critical for stable loop response in linear regulator error amplifiers.
Exposed collector pad (Pins 2 & 4)	Reduces thermal resistance by up to 51% vs. standard SOT223 footprint; allows >1 W dissipation with 6 cm² copper area.
AEC-Q101 qualification	Validates robustness against temperature cycling, humidity, and mechanical stress-required for automotive body control modules and lighting drivers.
Medium power capability in SMD	Delivers 1 A switching in 6.7 mm × 3.7 mm footprint-enables compact, high-density power stage designs without through-hole components.
Low V_CE(sat)	−0.5 V max reduces conduction loss by ~40% vs. generic PNP transistors at 500 mA-improves efficiency in battery-powered high-side loads.

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 package (3-lead, no Pin 4); lower P_tot = 0.50 W on standard FR4; same −60 V/−1 A rating and h_FE selection.	Limited thermal headroom in high-ambient environments; unsuitable where >0.65 W dissipation is required.	Select when board space is constrained and thermal load ≤0.5 W; verify R_th(j-a) = 250 K/W meets junction temp budget.
BC52PA,115	SOT1061 (HUSON3) ultra-thin 2×2×0.65 mm package; P_tot = 0.42 W on standard FR4; h_FE = 63–250 (no −10/−16 variants).	Designed for ultra-low-profile consumer wearables; lacks AEC-Q101 qualification and exposed thermal pad.	Choose only for space-constrained non-automotive applications where height <0.7 mm is mandatory and power <400 mW.

Compared with BCX52-10,115 and BC52PA,115, BCP52-10,135 offers superior thermal performance via dual-collector SOT223 and AEC-Q101 compliance-making it the sole choice for automotive-grade medium-power PNP switching where reliability and power density are jointly critical.

FAQ

What is the exact h_FE range for BCP52-10,135?

The BCP52-10,135 has a guaranteed DC current gain (h_FE) of 63 to 160 at V_CE = −2 V and I_C = −150 mA. This "−10" suffix denotes the mid-range h_FE bin, distinct from the −16 variant (100–250) and standard version (63–250). Gain is measured under controlled conditions and remains stable across −55 °C to +150 °C junction temperature.

Can BCP52-10,135 replace BCX52-10,115 in existing designs?

Yes, but with thermal and layout considerations: both share identical electrical specs (−60 V, −1 A, h_FE 63–160), but BCP52-10,135 uses SOT223 with dual collector pads (Pins 2 & 4), while BCX52-10,115 uses SOT89 with single collector (Pin 2). PCB footprint and thermal pad area must be updated to leverage the improved 0.65 W rating and 93 K/W R_th(j-a).

Is reflow soldering mandatory for BCP52-10,135?

Yes-Nexperia explicitly states reflow soldering is the only recommended method for BCP52-10,135 in SOT223. Wave soldering is not advised due to thermal stress risks from the exposed collector pad and internal bond wire construction. Reflow profile must comply with J-STD-020, peak temperature ≤260 °C, and time above 217 °C limited to 60–150 seconds.

Does BCP52-10,135 support pulsed operation beyond 1 A?

Yes-its I_CM (peak collector current) is −2 A for single pulses ≤1 ms, provided duty cycle and thermal design prevent junction temperature exceeding 150 °C. At 10% duty cycle, average current can reach ~200 mA continuously with adequate copper area; transient thermal impedance data (Fig 4–6) confirms safe operation under short-duration overload conditions.
