Product details
Overview
BC52-10PASX from Nexperia is a PNP medium power transistor in DFN2020D-3 (SOT1061D) package, rated for −60 V VCEO, −1 A continuous collector current, and 160 hFE at −150 mA/−2 V. It features exposed thermal pad, side-wettable flanks for AOI, and AEC-Q101 qualification-used in high-side switches and MOSFET drivers where compact size and automotive-grade reliability are required.
For engineers reviewing the BC52-10PASX datasheet, BC52-10PASX pinout, BC52-10PASX application, or BC52-10PASX equivalent, this page delivers verified electrical parameters, thermal derating curves, PCB footprint guidance, and validated alternatives for linear regulators, battery-powered systems, and power management circuits.
Technical Context
This PNP bipolar junction transistor operates with base-emitter forward bias to control collector current flow in medium-power analog and switching applications. Its −60 V VCEO and −2 A ICM support robust operation in automotive load switching and voltage regulation topologies.
The device uses a thermally enhanced DFN2020D-3 package with solderable side pads and an exposed collector pad, enabling low Rth(j-a) down to 76 K/W on 4-layer PCBs with 1 cm² copper pad-critical for sustained −1 A conduction without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit in high-side switch designs. |
| IC | −1 A - Continuous DC collector current rating; supports stable operation in linear regulators and driver stages without forced air cooling. |
| hFE | 63–160 - DC current gain range at VCE = −2 V, IC = −150 mA; enables predictable base drive sizing for MOSFET gate control. |
| VCE(sat) | −500 mV max at IC = −500 mA, IB = −50 mA - Low saturation voltage minimizes power loss and self-heating in switching applications. |
| Ptot | 1.65 W at Tamb ≤ 25 °C on 4-layer FR4 with 1 cm² collector pad - Enables higher power density than standard SOT-23 equivalents. |
| fT | 145 MHz - Transition frequency supports stable operation up to audio-frequency amplification and fast-switching control loops. |
| Rth(j-a) | 76 K/W min - Thermal resistance achievable with optimized PCB layout; allows ~15 °C junction rise above ambient at full 1 A load. |
Pinout & Package
DFN2020D-3 (SOT1061D) is a 2 mm × 2 mm × 0.65 mm ultra-thin leadless plastic package with side-wettable flanks and an exposed collector thermal pad on the bottom surface. The package supports automated optical inspection (AOI) and offers superior thermal performance over traditional SOT-23 or SC-70 packages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires −50 mA base current to saturate at −500 mA collector load-enables direct MCU GPIO drive with series resistor. |
| 2 | Emitter (E) | Current source node; connected to positive supply rail in high-side switch configuration; must be routed with low-inductance trace. |
| 3 | Collector (C) | Output terminal and thermal path; electrically and thermally tied to exposed bottom pad-requires full-solder coverage for optimal Rth. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−55 °C to +150 °C) and stress testing-enables use in engine control, body electronics, and ADAS power stages. |
| Side-wettable flanks | Enables reliable automated optical inspection (AOI) of solder joints without X-ray-reduces post-reflow defect escape in high-volume manufacturing. |
| Exposed collector pad | Provides dual-path conduction: electrical output + thermal dissipation-reduces junction-to-ambient resistance by up to 50% vs. non-exposed DFN variants. |
| Two hFE grades | BC52-10PASX (63–160) and BC52-16PASX (100–250) allow precise gain matching across production batches for consistent driver loop behavior. |
Applications
| Linear Voltage Regulators | Battery-Driven Devices |
|---|---|

Use Scenario: Current-sense amplifier front-end in USB-C PD power delivery controller. IC Role / Device Role / Timing Role: Precision current mirror element providing scaled replica of load current to ADC input. Use Value: Tight hFE tolerance (63–160) and low ICBO (<100 nA at 25 °C) ensure <1% gain error across temperature and process variation. |
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 |
|---|---|---|---|
| BC807-16X | Same SOT-23 package; lower VCEO (−45 V), lower Ptot (0.3 W), no AEC-Q101 qualification. | Suitable only for consumer-grade 5–24 V systems; not recommended for automotive or industrial environments. | Select when cost and board space are critical, and automotive qualification is unnecessary. |
| MBT3906DW1T1G | SC-70 package; −40 V VCEO, −200 mA IC, no exposed thermal pad, AEC-Q101 qualified. | Limited to low-current signal switching; insufficient for 1 A load switching or regulator pass applications. | Choose only for low-power logic-level inversion or biasing where thermal performance is secondary. |
Compared with BC52-10PASX, BC807-16X trades automotive reliability and thermal capability for lower cost and legacy footprint compatibility, while MBT3906DW1T1G sacrifices current handling and package thermal efficiency to meet ultra-compact layout constraints-neither matches BC52-10PASX's combination of 1 A rating, −60 V breakdown, and AEC-Q101 compliance in a 2 mm × 2 mm footprint.

FAQ
What is the maximum allowable junction temperature for BC52-10PASX?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold causes permanent degradation. Derating is required above 25 °C ambient-e.g., at 85 °C ambient, maximum continuous IC drops to ~0.65 A on a 4-layer PCB with 1 cm² collector pad.
Does BC52-10PASX require a heatsink for 1 A continuous operation?
No external heatsink is required if mounted on a properly designed PCB: 4-layer FR4 with ≥1 cm² copper area connected to the exposed collector pad achieves Rth(j-a) = 76 K/W, limiting junction rise to ~115 °C at 1 A and 25 °C ambient-within safe operating limits.
How does the side-wettable flank design aid manufacturing?
The side-wettable flanks enable automated optical inspection (AOI) of solder joint quality on the solder fillet along the package edge-eliminating need for X-ray inspection in high-volume SMT lines and reducing false call rates in functional test.
Can BC52-10PASX replace BC52-16PASX in existing designs?
Yes, but with gain trade-off: BC52-10PASX has hFE = 63–160 vs. BC52-16PASX's 100–250 at same conditions. Base drive must be re-evaluated-especially in linear applications where gain affects loop stability and quiescent current.
