Product details
Overview
BCP52,135 from Nexperia is a PNP medium-power bipolar junction transistor in SOT223 (SC-73) surface-mount package, rated for −60 V VCEO, −1 A continuous collector current, and 0.65 W power dissipation on standard FR4 PCB. It features three hFE gain selections (63–250), AEC-Q101 qualification, and an exposed collector pad for thermal and electrical conduction. It is used in linear voltage regulators and high-side switching circuits requiring robust thermal performance.
For engineers reviewing the BCP52,135 datasheet, BCP52,135 pinout, BCP52,135 application, or BCP52,135 equivalent, this page delivers verified specifications, validated SOT223 pin mapping, automotive-grade reliability context, and real-world use cases in battery-driven power management and MOSFET driver stages - all grounded in Nexperia's Rev. 9 product data sheet.
Technical Context
The BCP52,135 operates as a silicon PNP BJT with fixed-emitter configuration and base-controlled current amplification. Its design supports linear regulation and switching modes, with VCE(sat) ≤ −0.5 V at IC = −500 mA / IB = −50 mA and fT = 145 MHz at VCE = −5 V / IC = −50 mA.
Thermal behavior is defined by Rth(j-a) = 192 K/W (standard footprint), Rth(j-sp) = 16 K/W, and transient impedance curves showing strong pulse-handling capability up to 2 ms. The device is qualified per AEC-Q101 for automotive underhood environments with Tj ≤ 150 °C and Tstg = −65 to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V: Maximum safe collector-emitter blocking voltage in open-base configuration. |
| IC | −1 A: Continuous DC collector current rating under specified PCB thermal conditions. |
| Ptot | 0.65 W: Total power dissipation limit on single-layer FR4 with standard footprint. |
| hFE | 63–250: DC current gain range at VCE = −2 V, IC = −150 mA; selection-dependent. |
| VCE(sat) | ≤ −0.5 V: Collector-emitter saturation voltage ensures low conduction loss in switching applications. |
| fT | 145 MHz: Transition frequency confirms suitability for moderate-speed switching and analog amplification. |
| Rth(j-sp) | 16 K/W: Low junction-to-solder-point thermal resistance enables efficient heat transfer to PCB copper. |
Pinout & Package
SOT223 (SC-73) plastic surface-mounted package with 4 leads: three signal terminals (base, collector, emitter) plus an exposed collector pad acting as terminal 4 for enhanced thermal and electrical conductivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control electrode; accepts base current to regulate collector-emitter conduction. |
| 2 | Collector | Main current-carrying terminal; electrically and thermally connected to exposed pad (pin 4). |
| 3 | Emiter | Current return path; tied to system ground or load return in high-side switch configurations. |
| 4 | Collector (exposed pad) | Thermal and electrical extension of pin 2; must be soldered to large copper area for rated power handling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood use with extended temperature cycling and humidity testing. |
| Three hFE selections | Gain bins (−10, −16, standard) enable precise biasing in linear regulators and feedback loops. |
| Exposed collector pad | Reduces thermal resistance by >80% vs. non-exposed packages, enabling higher sustained current in compact layouts. |
| High power dissipation | 1.35 W achievable with 6 cm² collector pad on FR4 - supports space-constrained industrial power stages. |
| Low VCE(sat) | Ensures <100 mW conduction loss at 500 mA, critical for efficiency in battery-powered high-side switches. |
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 |
|---|---|---|---|
| BCX52,115 | SOT89 package (3-pin, no exposed pad); lower Ptot = 0.50 W on standard footprint; same VCEO/IC ratings. | Limited thermal headroom in high-duty-cycle switching; unsuitable for >0.7 A continuous in unheatsinked designs. | Select when board space is constrained and thermal budget permits reduced power derating. |
| BC52PA,115 | SOT1061 ultra-thin package (2 × 2 × 0.65 mm); Ptot = 0.42 W on standard footprint; AEC-Q101 qualified. | Optimized for ultra-low-profile consumer wearables; requires 4-layer PCB for full 1.10 W rating. | Choose for height-sensitive applications where 0.65 mm max profile is mandatory and layer count can be increased. |
Compared with BCX52,115 and BC52PA,115, the BCP52,135 delivers superior thermal performance via its SOT223 exposed-pad architecture - enabling 1 A continuous operation on 2-layer FR4 without forced cooling, while maintaining identical automotive qualification and gain binning flexibility.

FAQ
What is the maximum allowable junction temperature for BCP52,135?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this temperature risks permanent degradation of hFE, leakage current, and bond wire integrity. Thermal design must ensure Tj remains below 150 °C under worst-case ambient and power dissipation conditions.
Does BCP52,135 require a heatsink for 1 A continuous operation?
No external heatsink is required if the exposed collector pad (pin 4) is soldered to ≥1 cm² of 1-oz copper on a single-layer FR4 PCB, enabling 1.00 W dissipation. On standard footprint (no added copper), 0.65 W limits continuous current to ~750 mA; full 1 A requires thermal enhancement per Figure 1.
How does the hFE selection affect circuit design?
The BCP52,135 is offered in three hFE bins: standard (63–250), −10 (63–160), and −16 (100–250). Designers select based on required base drive current - e.g., −16 bin reduces base current by ~40% vs. standard at IC = −150 mA, easing drive requirements in low-power controllers.
Is BCP52,135 compatible with lead-free reflow soldering profiles?
Yes - BCP52,135 is qualified for lead-free reflow per JEDEC J-STD-020. The recommended peak temperature is 260 °C (max), with time above liquidus ≤60 seconds. Reflow footprint dimensions and solder paste stencil design are specified in Figure 22 of the datasheet.
