Product details
Overview
BCX5616TA from Diodes Incorporated is an NPN medium-power transistor in SOT89 package, rated for 80V VCEO, 1A continuous collector current, and <500mV VCE(sat) at 500mA/50mA drive-designed for AF output stages and medium-power switching in industrial power supplies and motor drivers.
For engineers reviewing the BCX5616TA datasheet, BCX5616TA pinout, BCX5616TA application, or BCX5616TA equivalent, key selection criteria include verified VCEO=80V rating, SOT89 thermal performance (RθJL=13°C/W), hFE range of 100–250 at 150mA, and automotive-qualified packaging options.
Technical Context
This device uses epitaxial planar die construction to achieve stable hFE across temperature and low saturation voltage. Its 80V VCEO and 100V VCBO support operation in 48V bus systems with margin, while fT=150MHz enables use in audio-frequency amplification up to ~20kHz with adequate gain.
The SOT89 package features an exposed collector pad thermally coupled to PCB copper, delivering RθJL=13°C/W and enabling 1.5W dissipation on 15mm×15mm 1oz copper-critical for sustained 1A switching without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports 48V rail switching with 67% voltage margin against transients. |
| IC (continuous) | 1 A - Delivers sufficient current for relay drivers, fan controllers, and Class-B audio outputs. |
| VCE(sat) | <0.5 V @ 500mA/50mA - Minimizes conduction loss and self-heating in linear or saturated switching. |
| hFE | 100–250 @ 150mA - Ensures reliable base drive design across production lots and temperature range. |
| fT | 150 MHz - Provides usable gain beyond audio band, supporting wideband preamp or RF buffer roles. |
| RθJL | 13 °C/W - Enables direct thermal path from junction to PCB, critical for high-duty-cycle operation. |
Pinout & Package
Package: SOT89 - Molded plastic, green compound (UL 94V-0), matte tin finish leads, 0.055g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main current sink terminal | Exposed metal pad on underside - must be soldered to ≥15mm² copper for thermal compliance. |
| Emitter (E) | Current return path | Low-inductance connection point; referenced to system ground in common-emitter configurations. |
| Base (B) | Control input | Receives current-limited drive (max 100mA DC); requires series resistor to limit IB per hFE target. |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Ensures tight hFE distribution and stable β across -55°C to +150°C operating range. |
| VCE(sat) < 500 mV @ 500 mA | Reduces power loss to ≤250 mW at full rated current, lowering thermal stress in compact layouts. |
| Complementary PNP pairing (BCX53) | Enables push-pull output stage implementation with matched thermal and gain characteristics. |
| AEC-Q101 qualified variants available | Supports automotive-grade designs requiring PPAP documentation and IATF 16949 manufacturing traceability. |
Applications
| Audio Power Output Stage | DC Motor Driver (12–48V) |
|---|---|
|
Use Scenario: Driving 8Ω speaker loads in battery-powered portable audio amplifiers. IC Role / Device Role / Timing Role: NPN switch in Class-B output stage, biased by resistive divider and driven by op-amp or PWM controller. Use Value: Low VCE(sat) minimizes heat generation at 500mA peak, while 80V rating accommodates 2× supply ripple without breakdown. |
Use Scenario: Controlling brushed DC motors in HVAC actuators and industrial valve positioners. IC Role / Device Role / Timing Role: Medium-current switch in H-bridge half-bridge leg or single-direction driver with flyback diode. Use Value: 1A continuous rating supports 5W mechanical output; SOT89 thermal design allows >60s duty cycle at full load without heatsink. |
| Industrial Relay Driver | Power Supply Pass Transistor |
|
Use Scenario: Driving 12V/24V coil relays in PLC I/O modules and building automation panels. IC Role / Device Role / Timing Role: Saturated switch interfacing microcontroller GPIO to inductive load via base resistor network. Use Value: High hFE (≥100) reduces required base drive current to <10mA, easing MCU port loading and reducing BOM count. |
Use Scenario: Linear pass element in adjustable 3.3V/5V/12V regulators for noise-sensitive analog subsystems. IC Role / Device Role / Timing Role: Series pass transistor controlled by error amplifier in discrete LDO topology. Use Value: 80V VCEO and 1.5W dissipation capability enable safe operation with 24V input and 1A load under worst-case dropout conditions. |
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 |
|---|---|---|---|
| BCX56TA | Same die, identical electrical specs, but marked 'BH' and shipped in 7″ reel (1000 pcs) vs. BL marking and same reel size. | No functional difference; used interchangeably where marking or tape/reel logistics are not controlled. | Select BCX5616TA when BL marking or specific reel configuration is required by production line setup. |
| MJD127G | Higher VCEO=100V, higher IC=2A, TO-252 package, RθJA=60°C/W (vs. 83°C/W for BCX5616TA on same copper). | Better suited for higher-power or higher-reliability industrial switching where PCB space permits DPAK footprint. | Choose MJD127G when >1A peak current or >1.5W dissipation is needed; BCX5616TA remains optimal for space-constrained SOT89 layouts. |
Compared with BCX56TA, BCX5616TA offers identical performance with differentiated marking and packaging; versus MJD127G, it trades higher power handling for smaller footprint and lower assembly cost in SMT lines optimized for SOT89.

FAQ
What is the maximum continuous collector current for BCX5616TA?
The BCX5616TA is rated for 1A continuous collector current (IC) at TA = +25°C with proper PCB copper area. Derating applies above 25°C ambient: power dissipation drops linearly to zero at +150°C junction temperature, per the 1.5W rating on 15mm×15mm 1oz copper.
Is BCX5616TA suitable for automotive applications?
BCX5616TA itself is not AEC-Q101 qualified, but Diodes offers functionally identical AEC-Q101-certified versions (e.g., BCX56Q-13) manufactured in IATF 16949 facilities. For automotive use, specify the Q-suffix part number and engage Diodes' automotive team for PPAP support.
How does the SOT89 package improve thermal performance over SOT23?
The SOT89's exposed collector pad provides a direct thermal path to PCB copper, achieving RθJL = 13°C/W-over 5× better than typical SOT23 RθJA. This allows 1.5W dissipation on modest copper area, whereas SOT23 would require heatsinking or derating below 300mW for equivalent reliability.
What is the minimum hFE guaranteed at 150mA collector current?
The BCX5616TA guarantees hFE ≥ 100 at IC = 150mA, VCE = 2V, and TA = +25°C. This is specified in the Electrical Characteristics table and confirmed across production lots; no binning is required to meet this minimum.
