Product details
Overview
BCP5616QTA from Diodes Incorporated is an AEC-Q101 qualified 80V NPN medium-power 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-designed for automotive-grade switching and amplification in engine control modules and body electronics.
For engineers reviewing the BCP5616QTA datasheet, BCP5616QTA pinout, BCP5616QTA application, or BCP5616QTA equivalent, key selection criteria include its 80V VCEO, 100–250 hFE range across 5 mA–500 mA, 100 MHz fT, AEC-Q101 qualification, and SOT223 thermal performance with RθJA = 62°C/W on 50 mm × 50 mm 1 oz copper.
Technical Context
This NPN BJT operates as a medium-power linear amplifier or saturated switch in automotive subsystems, supporting DC and pulsed operation up to 2 A peak with guaranteed BVCEO ≥ 80 V and low saturation voltage under defined IC/IB conditions. Its hFE is specified across three current levels (5 mA, 150 mA, 500 mA), enabling stable gain behavior in both small-signal driver and medium-current output stages.
Thermally, it leverages the SOT223 package's exposed collector tab for enhanced heat transfer, with RθJL = 19.4°C/W to leads and derated power dissipation above +25°C ambient-critical for under-hood applications where ambient exceeds 105°C and PCB copper area is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Ensures safe operation in 24 V automotive systems with load-dump transients up to 87 V. |
| IC (continuous) | 1 A - Supports sustained switching of solenoids, relays, and LED arrays without forced cooling. |
| VCE(SAT) | < 500 mV @ 500 mA / 50 mA - Minimizes conduction loss and self-heating in saturated-switch configurations. |
| fT | 100–150 MHz - Enables use in AF amplification and fast-switching PWM drivers up to ~10 MHz. |
| hFE | 25–250 - Provides predictable current gain across 5 mA–500 mA, supporting both biasing and gain-stable amplification. |
| RθJA | 62 °C/W - Requires ≥50 mm × 50 mm 1 oz copper pad for full 2 W dissipation at TA ≤ 70°C. |
| ESD HBM | 4000 V - Meets IEC 61000-4-2 Level 3 for robustness in assembly and system-level handling. |
Pinout & Package
SOT223 package with molded green plastic case (UL 94V-0), 0.112 g mass, matte tin-plated leads solderable per MIL-STD-202 Method 208, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Emitter (E) | Current sink terminal | Connected to ground or low-side return path; electrically isolated from heatsink via plastic body. |
| Base (B) | Control input | Receives forward-biased current to drive transistor into active or saturation region; requires series resistor for current limiting. |
| Collector (C) | High-current output terminal | Exposed metal tab serves as primary thermal path and high-current connection; must be soldered to large copper area for thermal management. |
| Collector Tab (C) | Thermal & electrical node | Electrically identical to Collector pin; provides mechanical mounting and thermal interface-no isolation from PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive temperature range (−55°C to +150°C) and reliability stress tests including HTOL, TC, and ESD. |
| Low VCE(SAT) | < 500 mV at IC = 500 mA ensures <1.5 W conduction loss in saturated switching, reducing thermal load in space-constrained modules. |
| Complementary PNP pair | BCP5316Q available for push-pull or H-bridge topologies requiring matched voltage/current ratings and thermal profiles. |
| Green compound & lead-free | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets global environmental compliance mandates. |
Applications
| Engine Control Unit (ECU) Injector Driver | Automotive HVAC Blower Motor Control |
|---|---|
Use Scenario: Driving 12 V fuel injector coils with 5–10 ms pulse width and 1 A peak current in closed-loop combustion timing circuits. IC Role / Device Role / Timing Role: NPN switch operating in saturation mode with fast turn-on/turn-off enabled by hFE ≥ 100 at 150 mA and fT ≥ 100 MHz. Use Value: Low VCE(SAT) minimizes coil heating and improves pulse fidelity; AEC-Q101 rating ensures reliability over 15-year vehicle lifetime. | Use Scenario: Controlling brushed DC blower motor speed via PWM in climate control systems, operating continuously at 0.8 A average current. IC Role / Device Role / Timing Role: Medium-power linear or switched regulator pass element, dissipating up to 1.2 W during partial-load operation. Use Value: 2 W power rating and RθJA = 62°C/W allow operation without heatsink on standard 2-layer automotive PCBs. |
| Body Control Module (BCM) Relay Interface | LED Headlamp Dimming Circuit |
Use Scenario: Replacing mechanical relays for door lock actuators and window lift motors in BCMs, switching 24 V loads with 1 A steady-state current. IC Role / Device Role / Timing Role: High-voltage NPN switch with 80 V VCEO providing margin against 24 V load-dump spikes (up to 87 V). Use Value: BVCEO ≥ 80 V eliminates need for external TVS clamping in many 24 V architectures, reducing BOM count. | Use Scenario: Analog dimming of high-brightness LED strings in adaptive front-lighting systems, delivering 0.5–1 A with precise current regulation. IC Role / Device Role / Timing Role: Linear current source configured with emitter degeneration resistor and base voltage reference. Use Value: Tight hFE distribution (25–250) and low VBE(on) variation enable stable current setting across temperature and unit-to-unit variance. |
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 |
|---|---|---|---|
| ZTX653 | Higher VCEO (100 V), lower hFE (min 100), same SOT223 package but non-AEC-Q101 rated. | Not qualified for automotive production; suitable for industrial or consumer designs requiring higher voltage margin. | Select if AEC-Q101 is not required and 100 V breakdown is critical; verify thermal design with RθJA = 70°C/W. |
| BCP56-16 | Same die, non-automotive grade version-lacks AEC-Q101 test records, PPAP capability, and IATF16949 manufacturing traceability. | Acceptable for non-safety-critical aftermarket or prototyping; not approved for OEM Tier 1 production release. | Choose only for cost-sensitive non-automotive applications where qualification documentation is unnecessary. |
Compared with ZTX653 and BCP56-16, BCP5616QTA delivers verified automotive qualification, tighter parametric consistency across temperature, and full supply-chain traceability-making it the sole choice for production ECU, BCM, and lighting modules requiring change-controlled component sourcing.

FAQ
What is the maximum allowable junction temperature for BCP5616QTA?
The absolute maximum junction temperature is +150°C, with continuous operation permitted from −55°C to +150°C ambient when derated per the datasheet's thermal curves. At 25°C ambient, full 2 W dissipation is allowed; above 70°C ambient, power must be linearly reduced to maintain TJ ≤ 150°C using RθJA = 62°C/W.
Is BCP5616QTA pin-compatible with BCP56-16?
Yes-both share identical SOT223 pinout (Emitter, Base, Collector, Collector tab) and mechanical footprint. However, BCP5616QTA includes automotive-specific test screening, lot-level PPAP documentation, and IATF16949 manufacturing controls not present in BCP56-16.
Does BCP5616QTA require a heatsink in typical automotive applications?
No external heatsink is required if mounted on ≥50 mm × 50 mm 1 oz copper area per the JEDEC standard test condition. In compact modules with limited copper, thermal vias under the collector tab and internal layer copper pours are recommended to maintain TJ < 130°C at 1 A continuous load.
Can BCP5616QTA be used in linear amplifier configurations?
Yes-it is characterized for linear operation with hFE specified at multiple IC points and fT = 100–150 MHz. For audio-frequency amplification, ensure VCE remains >2 V to avoid saturation, and limit power dissipation to ≤1.5 W with adequate PCB copper to prevent thermal runaway.
