Product details
Overview
BCP52TA from Diodes Incorporated is a PNP medium-power bipolar junction transistor in SOT223 package, rated for -60V collector-emitter breakdown voltage, -1A continuous collector current, and 2W power dissipation. It delivers low saturation voltage (≤ -500mV at -500mA/-50mA), supports gain groups 10 and 16, and is AEC-Q101 qualified for automotive-grade reliability in medium-power switching applications such as AF output stages.
For engineers reviewing the BCP52TA datasheet, BCP52TA pinout, BCP52TA application, or BCP52TA equivalent, key selection criteria include verified VCEO = -60V, hFE range (63–160 @ -150mA), thermal resistance RθJL = 19.4°C/W, and SOT223 mechanical compatibility with surface-mount PCB layouts requiring robust thermal conduction via collector lead.
Technical Context
The BCP52TA operates as a single PNP silicon transistor optimized for linear amplification and saturated switching in medium-current DC paths. Its design emphasizes stable hFE across temperature (-65°C to +150°C), low VCE(sat) under high IC, and controlled capacitance (Cobo ≤ 25pF @ -10V) for predictable frequency response up to 150MHz fT.
It uses a planar epitaxial structure with fully lead-free, halogen- and antimony-free "Green" molding compound (UL 94V-0), and meets J-STD-020 moisture sensitivity Level 1. The device shares electrical and thermal characteristics with its automotive-grade counterpart BCP52QTA but differs only in marking and PPAP documentation support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60V - Maximum safe collector-emitter voltage before avalanche breakdown in common-emitter configuration. |
| IC (cont.) | -1A - Continuous DC collector current capability without thermal derating on 50mm × 50mm 1oz Cu PCB. |
| VCE(sat) | ≤ -500mV @ -500mA/-50mA - Ensures minimal power loss and heat generation during switch-on operation. |
| hFE | 63–160 @ -150mA/VCE = -2V - Gain group 10/16 enables predictable biasing in amplifier and driver circuits. |
| fT | 150MHz - Supports audio-frequency amplification and fast-switching control up to ~10MHz practical bandwidth. |
| RθJL | 19.4°C/W - Low junction-to-lead thermal resistance allows efficient heat transfer through soldered collector pad. |
| ESD HBM | 4,000V - Robust handling tolerance against human-body electrostatic discharge during assembly. |
Pinout & Package
Package: SOT223 - Surface-mount plastic package with exposed collector tab for thermal and electrical connection; dimensions per AP02002 (D = 6.50mm, E = 3.50mm, E1 = 7.00mm, L = 0.95mm); weight ≈ 0.112g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter terminal | Current exit path in PNP operation; connected to higher potential node in switching circuits. |
| Pin 2 (Base) | Control input | Receives negative base current to turn on transistor; requires current-limiting resistor in most designs. |
| Pin 3 (Collector) | Main current path | Electrically and thermally tied to large copper pad; serves as primary heat sink and high-current return path. |
| Pin 4 (Collector Tab) | Collector extension | Exposed metal tab electrically connected to Pin 3; must be soldered to PCB ground or power plane for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and body electronics requiring extended temperature and lifetime reliability. |
| 2W power dissipation | Enables direct replacement of TO-92 or SOT-89 devices in space-constrained PCBs without external heatsinks. |
| Low VCE(sat) | Reduces conduction losses by >30% vs. standard PNP transistors at -500mA, improving efficiency in battery-powered drivers. |
| Gain grouping (10/16) | Allows selective binning for consistent performance in production batches-critical for matched-pair amplifier designs. |
| Halogen- and antimony-free "Green" construction | Meets global environmental compliance mandates (RoHS 2, JEDEC J-STD-020) without compromising thermal or electrical performance. |
Applications
| Audio Frequency Output Stage | Automotive Door Lock Driver |

IC Role / Device Role / Timing Role: Medium-power switching element interfacing microcontroller GPIO to inductive load. Use Value: -60V VCEO withstands load-dump transients; AEC-Q101 rating ensures 15-year field reliability under vibration and thermal cycling. |
| DC Motor Speed Control | Industrial Sensor Signal Conditioning |
Use Scenario: PWM-driven H-bridge half-bridge leg for 24V brushed DC motors in factory automation. IC Role / Device Role / Timing Role: High-side PNP switch enabling bidirectional current flow with logic-level gate drive. Use Value: 150MHz fT supports clean switching at 20kHz PWM frequencies; RθJL = 19.4°C/W prevents thermal runaway during burst-mode operation. | Use Scenario: Amplifying low-level thermocouple or strain gauge signals in programmable logic controller (PLC) analog input modules. IC Role / Device Role / Timing Role: Linear amplifier stage providing fixed-gain signal boosting prior to ADC sampling. Use Value: Stable hFE over -40°C to +85°C ensures ±0.5% gain drift; low noise floor preserves microvolt-level signal integrity. |
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 |
|---|---|---|---|
| BCP5210TA | Same package and ratings, but hFE min = 63 (gain group 10) - narrower spread than standard BCP52TA (63–160). | Suitable where tighter hFE tolerance is required for matched amplifier pairs or feedback loop stability. | Select when circuit gain consistency across units is critical; not recommended for general-purpose switching where wider hFE improves margin. |
| BCP5216TA | Same package and ratings, but hFE min = 100 (gain group 16) - higher minimum gain than standard BCP52TA. | Better suited for low-base-drive applications like microcontroller-driven loads where IB < -20mA is constrained. | Choose when driving from weak GPIOs or when minimizing base current consumption is essential; may require recalculating base resistor values. |
Compared with BCP52TA, BCP5210TA offers tighter hFE control for precision analog use, while BCP5216TA provides higher guaranteed gain for low-drive digital switching-both retain identical voltage, current, thermal, and automotive qualifications.

FAQ
What is the maximum operating temperature for BCP52TA?
The BCP52TA has an operating junction temperature range of -65°C to +150°C, with thermal derating beginning above +25°C ambient. On a 50mm × 50mm 1oz copper PCB, full 2W power dissipation is valid only up to +70°C ambient; beyond that, linear derating applies at 16.1mW/°C based on RθJA = 62°C/W.
Is BCP52TA pin-compatible with NPN counterparts like BCP54TA?
No-BCP52TA (PNP) and BCP54TA (NPN) share the same SOT223 package outline and pin numbering (Emitter-Base-Collector-Tab), but polarity reversal means direct substitution requires circuit redesign. Their pinouts match mechanically, but electrical behavior is complementary, not interchangeable.
Does BCP52TA require a heatsink in typical applications?
Not typically-its RθJL = 19.4°C/W enables effective heat transfer through the soldered collector tab to PCB copper. With ≥ 250mm² of 1oz copper connected to Pin 3/Tab, it dissipates 2W at ≤ 50°C rise. Heatsinks are unnecessary unless ambient exceeds +85°C or board copper area is severely restricted.
How does BCP52TA differ from the automotive-grade BCP52QTA?
BCP52QTA is identical electrically and thermally to BCP52TA but carries additional automotive-specific documentation: full PPAP submission support, AEC-Q101 test reports with lot traceability, and enhanced process controls. Both share the same die, SOT223 package, and marking layout-only compliance documentation and packaging labeling differ.
