Product details
Overview
BCP5410TA from Diodes Incorporated is an NPN medium-power bipolar junction transistor in SOT223 package, rated for 45V VCEO, 1A continuous collector current, and 2W power dissipation. It features low saturation voltage (VCE(sat) ≤ 500 mV @ 500 mA/50 mA), DC current gain group 10 (hFE = 63–160 @ 150 mA), and 150 MHz transition frequency - used in automotive audio output stages and industrial relay drivers.
For engineers reviewing the BCP5410TA datasheet, BCP5410TA pinout, BCP5410TA application, or BCP5410TA equivalent, this page delivers verified electrical parameters, thermal derating curves, gain-group-specific hFE behavior, and SOT223 mounting guidance - all critical for medium-power switching reliability and thermal margin validation in 12V/24V embedded systems.
Technical Context
The BCP5410TA operates as a silicon NPN transistor with fixed gain binning (Group 10), optimized for linear amplification and saturated switching in medium-current applications. Its 45V VCEO rating and 2W power dissipation support operation up to +150°C junction temperature, while its 62°C/W RθJA requires defined PCB copper area (50 mm × 50 mm, 1 oz) for thermal compliance.
It exhibits pulsed performance validated under ≤300 µs width and ≤2% duty cycle conditions, with VBE(on) ≤ 1.0 V at 500 mA and fT = 150 MHz at 50 mA/10 V - confirming suitability for AF driver stages and PWM-controlled load switching where bandwidth and saturation efficiency are jointly constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| IC (continuous) | 1 A - Continuous collector current capability without thermal runaway on specified PCB layout. |
| VCE(sat) | ≤ 500 mV @ IC = 500 mA, IB = 50 mA - Ensures <0.25 W conduction loss in saturated switch mode. |
| hFE (Group 10) | 63–160 @ IC = 150 mA, VCE = 2 V - Predictable DC gain range for bias network design stability. |
| fT | 150 MHz @ IC = 50 mA, VCE = 10 V - Supports audio-frequency amplification and fast-switching control loops. |
| RθJA | 62 °C/W - Requires ≥50 mm × 50 mm 1 oz copper pad for 2W operation at ambient ≤70°C. |
| ESD HBM | 4,000 V - Robust handling during board assembly without special ESD precautions. |
Pinout & Package
Package: SOT223 - surface-mount plastic package with exposed collector tab for thermal conduction; 0.112 g mass; UL 94V-0 rated molding compound; matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emission terminal for majority carriers | Connected to ground or low-side reference; carries full load current in common-emitter switch. |
| 2 (Base) | Control electrode for minority carrier injection | Driven by current-limited source (e.g., MCU GPIO via resistor); determines saturation depth and switching speed. |
| 3 (Collector) | Current collection terminal | Connected to load and supply rail; electrically and thermally tied to large copper area via exposed tab. |
| 4 (Collector Tab) | Thermal and electrical extension of collector | Must be soldered to ≥50 mm² copper pour for thermal management; not electrically isolated. |
Key Features
| Feature | Design Value |
|---|---|
| Gain Group 10 binning | hFE = 63–160 ensures consistent base drive requirements across production lots for stable bias design. |
| Low VCE(sat) | ≤500 mV at 500 mA enables <0.25 W conduction loss - critical for thermally constrained 12V relay drivers. |
| SOT223 thermal interface | Exposed collector tab allows direct thermal coupling to PCB copper, reducing junction-to-ambient resistance by ~43°C/W vs. SO-8. |
| AEC-Q101 readiness | Manufactured in IATF 16949-certified facilities; supports automotive qualification path with PPAP capability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP5416TA | Higher hFE bin (100–250 @ 150 mA); otherwise identical ratings and package. | Better suited for low-base-drive applications (e.g., weak GPIO sources); may require adjusted base resistor values. | Select when higher gain reduces base current demand or improves noise immunity in high-impedance bias networks. |
| MJD31C | TO-252 package; same VCEO = 45 V, but IC = 3 A and PD = 20 W; hFE = 10–60 (unbinned). | Used in higher-current, lower-frequency switching (e.g., solenoid drivers); requires larger PCB footprint and thermal mass. | Choose for >1 A continuous loads or when TO-252 mechanical robustness is required over SOT223 space constraints. |
Compared with BCP5410TA, BCP5416TA offers higher gain for reduced base drive overhead, while MJD31C provides triple the current capacity and tenfold power dissipation in a physically larger package - making BCP5410TA optimal for space-constrained 1A switching where predictable gain and thermal integration matter most.

FAQ
What is the difference between BCP5410TA and BCP54TA?
BCP54TA is the base version with unspecified hFE gain; BCP5410TA is binned to Gain Group 10 (hFE = 63–160 @ 150 mA). Both share identical absolute maximum ratings, package, and electrical characteristics except for guaranteed gain range - making BCP5410TA preferred for designs requiring predictable base drive current.
Can BCP5410TA replace BC817 in SOT23 packages?
No - BCP5410TA uses SOT223 with exposed collector tab and 2W power rating, while BC817 is SOT23-rated for 0.35W. Substituting would cause thermal failure under >350 mA loads. The pinouts also differ: BC817 is emitter-collector-base (ECB), whereas BCP5410TA is emitter-base-collector (EBC) in SOT223.
Is BCP5410TA qualified to AEC-Q101?
BCP5410TA is manufactured in IATF 16949-certified facilities and supports AEC-Q101 qualification upon request with PPAP documentation. While not pre-qualified out-of-box, Diodes provides change control, lot traceability, and test data necessary for customer-led AEC-Q101 certification in automotive applications.
What PCB layout guidance applies to the SOT223 thermal pad?
The SOT223 collector tab must be soldered to ≥50 mm² of 1 oz copper (minimum 7 mm × 7 mm) with ≥4 thermal vias (0.3 mm diameter, spaced ≤2 mm apart) connecting to internal/ground planes. This achieves the specified 62°C/W RθJA; smaller pads increase junction temperature by up to 35°C at full 2W load.
