Product details
Overview
BC53PA,115 from Nexperia is a PNP medium power transistor in SOT1061 leadless ultra-thin SMD package, rated for −80 V VCEO, −1 A continuous collector current, and 1.65 W total power dissipation at Tamb ≤ 25 °C with 4-layer PCB mounting. It delivers hFE = 63–250 at VCE = −2 V / IC = −150 mA and supports high-side switching in battery-powered linear regulators and MOSFET driver stages.
For engineers reviewing the BC53PA,115 datasheet, BC53PA,115 pinout, BC53PA,115 application, or BC53PA,115 equivalent, this device is selected for medium-power PNP switching where thermal performance, compact footprint (2 mm × 2 mm × 0.65 mm), and AEC-Q101-qualified reliability are required - especially in automotive-adjacent power management and amplifier biasing circuits.
Technical Context
The BC53PA,115 operates as a silicon PNP bipolar junction transistor optimized for linear and switching applications up to 100 MHz fT. Its exposed collector pad enables direct thermal coupling to PCB copper, supporting up to 1.65 W dissipation under 4-layer FR4 conditions. The device features pulsed ICM = −2 A and VCEO = −80 V, making it suitable for high-side load control in 24 V industrial systems.
It exhibits low VCE(sat) = −0.5 V at IC = −500 mA / IB = −50 mA and VBE = −1 V under same conditions, enabling efficient drive of downstream N-channel MOSFET gates. Its Cc = 15 pF and hFE stability across −55 °C to +150 °C support robust operation in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage with open base; defines upper rail limit for high-side switch design |
| IC | −1 A - Continuous DC collector current rating; supports ≥12 W load switching at 12 V supply |
| Ptot | 1.65 W - Max power dissipation on 4-layer FR4 with 1 cm² collector pad; enables compact thermal layout without heatsink |
| hFE | 63–250 - DC current gain range at VCE = −2 V / IC = −150 mA; ensures stable biasing across production lots |
| fT | 145 MHz - Transition frequency at VCE = −5 V / IC = −50 mA; supports fast switching in driver and RF amplifier stages |
| Rth(j-a) | 76 K/W - Junction-to-ambient thermal resistance on 4-layer FR4 with 1 cm² collector pad; enables <10 °C rise at 1 W dissipation |
Pinout & Package
SOT1061 is an ultra-thin (0.65 mm max height), leadless 3-terminal plastic package with exposed collector pad for enhanced thermal and electrical conduction. Dimensions: 2.1 mm × 1.9 mm body, 1.05 mm pitch between terminals, and standardized reflow footprint per Figure 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires ≥−50 mA base drive for full saturation at −500 mA collector load |
| 2 | Emitter (E) | Common reference terminal tied to positive rail in high-side configuration; carries full load current |
| 3 | Collector (C) | Main output terminal connected to load; electrically and thermally coupled to exposed bottom pad for PCB heat sinking |
Key Features
| Feature | Design Value |
|---|---|
| Exposed collector pad | Direct thermal path to PCB copper; reduces Rth(j-a) by up to 55% vs standard SOT packages |
| Three hFE variants | BC53PA (63–250), BC53-10PA (63–160), BC53-16PA (100–250) - enables precise gain matching in production batches |
| AEC-Q101 qualified | Stress-tested per Automotive Electronics Council standard; validated for temperature cycling, HTRB, and ESD per JESD22 |
| Ultra-thin SMD profile | 0.65 mm max height - enables stacking under connectors or in space-constrained modules like battery management units |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|
|
Use Scenario: Pass transistor in adjustable LDOs delivering 3.3 V/1 A from 12 V input. IC Role / Device Role / Timing Role: PNP pass element controlling output voltage via emitter-follower configuration with feedback to base. Use Value: Low VCE(sat) (−0.5 V) minimizes dropout voltage; high hFE reduces base drive burden on error amplifier. |
Use Scenario: Load switch enabling/disabling 24 V solenoid in industrial PLC I/O module. IC Role / Device Role / Timing Role: High-side PNP switch controlled by microcontroller GPIO through base resistor. Use Value: −80 V VCEO provides 3× safety margin over 24 V rail; exposed collector pad sustains 1.1 W dissipation during 100 ms inrush. |
| Battery-Driven Devices | MOSFET Drivers |
|
Use Scenario: Power path controller in portable medical monitor with dual Li-ion cells (8.4 V max). IC Role / Device Role / Timing Role: Reverse-polarity protection and load disconnect switch upstream of DC-DC converter. Use Value: −1 A IC handles peak loads; −5 V VEBO prevents damage during hot-swap events; SOT1061 footprint saves board area. |
Use Scenario: Level-shifting gate driver for N-channel MOSFET in half-bridge motor control. IC Role / Device Role / Timing Role: Active pull-up stage sourcing gate charge during high-side MOSFET turn-on. Use Value: 145 MHz fT supports ≤100 ns switching transitions; low Cc (15 pF) avoids Miller-effect delay in gate loop. |
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 |
|---|---|---|---|
| BCP53,115 | Same SOT1061 package, −80 V VCEO, but hFE = 63–250 at IC = −100 mA (not −150 mA); lower fT = 100 MHz | Less suitable for >100 kHz switching drivers; acceptable for DC/low-frequency linear regulation | Select when cost sensitivity outweighs gain consistency at higher collector currents |
| BC807-40,115 | SOT23 package, −45 V VCEO, −500 mA IC, hFE = 250–630 - smaller size but lower voltage/current capability | Only viable in ≤12 V systems; insufficient for 24 V high-side switches or 1 A loads | Choose only for space-constrained, low-voltage (<15 V), sub-500 mA applications where SOT1061 thermal advantage is unnecessary |
Compared with BC53PA,115, BCP53,115 trades gain stability at high current for broader availability, while BC807-40,115 sacrifices voltage headroom and thermal capacity for footprint reduction - neither matches BC53PA,115's combination of −80 V rating, −1 A current, and 1.65 W dissipation in ultra-thin SOT1061.

FAQ
Is BC53PA,115 still qualified to AEC-Q101?
No - per Revision 11 (September 2025), BC53PA,115 has been reclassified as non-automotive. The revision history explicitly states "BC53PA changed to non-automotive qualification" and directs users to nexperia.com for automotive (-Q) alternatives. Its qualification status was removed due to product line segmentation, not failure.
What is the maximum allowable PCB copper area for optimal thermal performance?
For 1.65 W dissipation, Nexperia specifies a 1 cm² mounting pad on a 4-layer FR4 PCB (Limiting Values Table 5, note [5]). Larger pads (e.g., 6 cm² on single-layer board) yield lower Rth(j-a) (114 K/W), but require careful layout to avoid solder mask bridging and ensure uniform reflow across the exposed collector pad.
How does BC53PA,115 differ from BC53-16PA,115 in practical circuit design?
BC53-16PA,115 guarantees minimum hFE = 100 at VCE = −2 V / IC = −150 mA (vs. 63 for BC53PA,115), enabling lower base drive current and tighter gain tolerance in critical bias networks. Both share identical VCEO, IC, and package - selection depends on required gain consistency, not voltage/current capability.
Can BC53PA,115 be used in avalanche mode?
No - the datasheet does not specify avalanche energy rating (EAS) or ruggedness testing. Its absolute maximum VCBO = −100 V and VCEO = −80 V indicate standard safe operating area limits only; operation beyond VCEO risks irreversible breakdown and is not supported by characterization data.
