Product details
Overview
BCP5610QTA from Diodes Incorporated is an AEC-Q101-qualified 80V NPN bipolar junction transistor in SOT223 package, rated for 1A continuous collector current, 2W power dissipation, and VCE(SAT) < 500 mV at 500 mA/50 mA drive-used in automotive medium-power switching stages such as body control module load drivers.
For engineers reviewing the BCP5610QTA datasheet, BCP5610QTA pinout, BCP5610QTA application, or BCP5610QTA equivalent, key selection criteria include breakdown voltage margin (VCEO = 80 V), thermal resistance (RθJA = 62 °C/W on 50 mm × 50 mm 1 oz Cu), and AEC-Q101 qualification for under-hood reliability.
Technical Context
This NPN transistor operates in linear amplification or saturated switching mode with hFE ranging from 25 to 160 across 5 mA–500 mA collector currents, and fT = 100–150 MHz at 50 mA/10 V, supporting audio driver and low-frequency signal amplification.
Its complementary PNP counterpart is BCP5316Q, enabling push-pull configurations; thermal design must account for RθJL = 19.4 °C/W (junction-to-leads) and derating above 25 °C ambient per the published curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Withstands 80 V collector-emitter voltage before breakdown, suitable for 24 V automotive systems with transient margin. |
| IC (continuous) | 1 A - Supports sustained load switching up to 1 A without thermal runaway on standard PCB copper. |
| PD | 2 W - Maximum steady-state power dissipation at TA = 25 °C with specified 50 mm × 50 mm 1 oz Cu layout. |
| VCE(SAT) | < 500 mV @ 500 mA/50 mA - Ensures low conduction loss and minimal self-heating in saturated switch applications. |
| hFE | 25–160 - Wide DC current gain range enables robust biasing across production lots and temperature extremes. |
| fT | 100–150 MHz - Supports high-fidelity AF amplification and fast switching up to ~10 MHz square-wave operation. |
| ESD HBM | 4000 V - Meets JEDEC JESD22-A114 Class 3A, reducing handling sensitivity in automated assembly. |
Pinout & Package
SOT223 package: 4-pin thermally enhanced plastic case with exposed collector tab (pin 3), lead-free matte tin plating, UL 94V-0 rating, and 0.112 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-side return path; electrically isolated from heatsink via plastic body. |
| 2 (Base) | Control input | Receives current-limited drive (max IB = 100 mA continuous); requires series resistor for saturation control. |
| 3 (Collector) | High-current output | Exposed metal tab serves as primary thermal path and electrical connection; must be soldered to copper pour. |
| 4 (Collector) | Redundant collector connection | Second collector lead improves current sharing and thermal conduction; tied internally to pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per stress test plan. |
| Low VCE(SAT) | Guarantees ≤500 mV drop at 500 mA, reducing power loss by >30% vs. legacy transistors with 700+ mV saturation. |
| Complementary pairing | Directly mates with BCP5316Q for balanced push-pull output stages in audio amplifiers and motor drivers. |
| Green compound | Halogen- and antimony-free molding compound (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb) meets automotive environmental mandates. |
Applications
| Automotive Body Control Module | Industrial 24 V Relay Driver |
|---|---|
Use Scenario: Driving solenoids, lamps, and small motors in door lock, window lift, and mirror control circuits. IC Role / Device Role / Timing Role: NPN switch controlling 24 V loads with PWM or ON/OFF logic-level input.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP56-10TA (ON Semiconductor) | VCEO = 80 V, IC = 1 A, but hFE min = 63 only (vs. 25 for BCP5610QTA); no AEC-Q101 certification. | Lacks automotive qualification; suitable for industrial non-safety-critical switching only. | Select when AEC-Q101 is not required and tighter hFE distribution is preferred. |
| MJD122G (ON Semiconductor) | Higher VCEO = 100 V, IC = 3 A, but SOT-223-3 (no redundant collector pin); RθJA = 70 °C/W (less efficient cooling). | Better voltage headroom but lower thermal performance; not pin-compatible due to 3-pin layout. | Choose for higher-voltage 48 V systems where thermal margin permits larger footprint or added heatsink. |
Compared with BCP56-10TA and MJD122G, the BCP5610QTA uniquely combines AEC-Q101 compliance, dual-collector thermal enhancement, and wide hFE range-making it optimal for cost-sensitive, thermally constrained automotive switching where qualification and manufacturability are mandatory.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The BCP5610QTA has an operating junction temperature range of –65 °C to +150 °C. For continuous operation, the maximum junction temperature is 150 °C; derating begins at 25 °C ambient, with power dissipation reduced linearly to zero at 150 °C based on RθJA = 62 °C/W and the published derating curve.
Is the SOT223 package's exposed collector tab electrically isolated?
No-the exposed collector tab (pin 3 and pin 4) is electrically connected to the collector semiconductor region and must be treated as a live high-current node. It is not insulated and requires appropriate clearance from grounded planes or other potentials in PCB layout.
Does the BCP5610QTA support pulse-width modulation (PWM) switching?
Yes-its 2 A peak pulse current (ICM) and low VCE(SAT) enable reliable PWM operation up to several hundred kHz, provided base drive is sufficient to ensure full saturation and storage time is managed via Baker clamp or optimized base resistor networks.
How does the BCP5610QTA differ from the BCP5610QTC variant?
The BCP5610QTA and BCP5610QTC share identical electrical and thermal specifications; the only difference is packaging-BCP5610QTA ships in 7-inch reels with 1000 units per reel, while BCP5610QTC uses 13-inch reels with 4000 units per reel-both are automotive-grade and AEC-Q101 qualified.
