Product details
Overview
BCP5110TA from Diodes Incorporated is a PNP 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 (< -500 mV at -500 mA), hFE gain group 10 (min 63 at -150 mA), and AEC-Q101 qualification for automotive reliability. It serves as a switching or linear amplification device in audio output stages and DC-DC converter control circuits.
For engineers reviewing the BCP5110TA datasheet, BCP5110TA pinout, BCP5110TA application, or BCP5110TA equivalent, key selection criteria include verified VCEO = -45 V, confirmed hFE group 10 performance across temperature, SOT223 thermal resistance (RθJL = 19.4 °C/W), and AEC-Q101 compliance for automotive-grade deployment.
Technical Context
This PNP transistor operates with emitter-grounded configuration and supports medium-power switching up to 1 A DC with pulsed capability to 2 A. Its gain group 10 ensures predictable hFE of 63–160 at -150 mA and -2 V VCE, enabling stable biasing in Class AB audio drivers and load-switching circuits.
Thermal design relies on its SOT223 package's low junction-to-leads resistance (19.4 °C/W) and 2 W steady-state dissipation on 50 mm × 50 mm 1 oz copper PCB. ESD robustness includes 4 kV HBM and 400 V MM ratings per JEDEC JESD22-A114/A115.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -45 V - Maximum safe collector-emitter reverse voltage before breakdown in common-emitter configuration. |
| IC (cont) | -1 A - Continuous collector current rating defining maximum DC load-handling capacity. |
| PD | 2 W - Steady-state power dissipation limit on standard FR4 PCB with defined copper area. |
| VCE(sat) | < -500 mV @ -500 mA / -50 mA - Ensures low conduction loss in saturated switching applications. |
| hFE Group | 10 - Gain range 63–160 at -150 mA, -2 V; enables consistent bias design without gain binning uncertainty. |
| fT | 150 MHz - Transition frequency supporting audio-frequency amplification and fast switching up to ~10 MHz. |
| ESD HBM | 4,000 V - Robustness against human-body electrostatic discharge during handling and assembly. |
Pinout & Package
SOT223 package: surface-mount, 4-pin thermally enhanced plastic case with exposed collector tab (pin 3). Molded "Green" compound (UL 94V-0), matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Main current exit path; connected to higher potential in PNP operation; requires low-impedance return path. |
| 2 (Base) | B | Control terminal; -100 mA max continuous base current defines drive capability for full saturation. |
| 3 (Collector) | C | Main current entry point; electrically and thermally tied to exposed metal tab for heatsinking. |
| 4 (Collector Tab) | C (thermal) | Integral thermal pad; must be soldered to PCB copper pour to achieve RθJL = 19.4 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments (-40°C to +150°C TJ) with PPAP documentation support. |
| Low VCE(sat) | < -500 mV at -500 mA ensures <0.25 W conduction loss, reducing thermal stress in high-duty-cycle switches. |
| Gain group 10 | hFE = 63–160 at -150 mA enables predictable bias network design without iterative trimming. |
| Halogen & antimony free | Meets "Green" definition: Br+Cl <1500 ppm, Sb <1000 ppm - compliant with global environmental regulations. |
Applications
| Automotive Door Module Switching | Audio Power Amplifier Driver |
|---|---|
Use Scenario: Driving window lift motor relays and LED status indicators in door control units. IC Role / Device Role / Timing Role: PNP switch controlling 12 V loads with logic-level base drive from MCU GPIO. Use Value: -45 V VCEO withstands automotive load-dump transients; AEC-Q101 ensures field reliability over 15-year vehicle life. |
Use Scenario: Output stage driver in Class AB headphone amplifier ICs or discrete preamp modules. IC Role / Device Role / Timing Role: Medium-current emitter-follower buffer delivering ±100 mA peak into 32 Ω loads. Use Value: Low VCE(sat) minimizes crossover distortion; fT = 150 MHz preserves audio bandwidth up to 20 kHz. |
| Industrial DC-DC Converter Control | Power Supply Enable Circuit |
Use Scenario: High-side switch for synchronous rectifier gate drive or auxiliary bias winding control in isolated SMPS. IC Role / Device Role / Timing Role: Fast-turning PNP switch enabling precise timing control of MOSFET gate signals. Use Value: 2 W power rating supports intermittent 1 A pulses; RθJL = 19.4 °C/W allows direct PCB thermal coupling without heatsink. |
Use Scenario: Enabling 5 V/3.3 V rails in multi-rail industrial controllers via microcontroller-controlled enable lines. IC Role / Device Role / Timing Role: Low-leakage, high-VCEO switch isolating downstream circuitry during standby. Use Value: ICBO ≤ -0.1 µA at -30 V ensures negligible standby current; -5 V VEBO prevents unintended turn-on from noise. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP51TA | VCEO = -45 V, same package and pinout, but hFE group unspecified (min 25); no guaranteed gain bin. | Lacks guaranteed hFE consistency - unsuitable where stable bias is required across production lots. | Select BCP5110TA when gain predictability is critical; choose BCP51TA only for non-critical, cost-sensitive switching. |
| BCP5210TA | VCEO = -60 V, otherwise identical electrical specs and gain group 10; higher voltage margin at same cost. | Supports 24 V industrial systems and higher transient immunity; compatible drop-in replacement where space permits. | Prefer BCP5210TA for 24 V rail applications or designs requiring headroom above 45 V; BCP5110TA remains optimal for 12 V automotive. |
Compared with BCP51TA, BCP5110TA delivers assured hFE consistency for stable bias networks, while BCP5210TA extends voltage capability to -60 V - both retain identical SOT223 thermal performance and AEC-Q101 qualification.

FAQ
What is the difference between BCP5110TA and BCP5116TA?
BCP5110TA has hFE gain group 10 (63–160 at -150 mA), while BCP5116TA has gain group 16 (100–250 at same conditions). Both share identical VCEO (-45 V), IC (-1 A), package, and AEC-Q101 qualification. Gain group selection determines bias stability requirements: group 16 allows lower base drive current but tighter gain tolerance.
Can BCP5110TA replace BCP5310TA in a 12 V system?
No - BCP5310TA is rated for -80 V VCEO, while BCP5110TA is rated for -45 V. Substituting it in a design originally specifying BCP5310TA risks premature breakdown under transients exceeding -45 V, even in nominal 12 V systems. Voltage rating must not be downgraded without circuit-level revalidation.
Is the exposed collector tab on BCP5110TA electrically isolated?
No - the exposed metal tab (pin 3) is internally connected to the collector terminal. It must be electrically tied to the collector net on the PCB and may not be used as a floating thermal pad. Thermal vias beneath the tab must connect only to collector copper, not ground or other potentials.
Does BCP5110TA require derating above 25°C ambient?
Yes - its 2 W power rating applies only at TA = +25°C. Derating begins immediately above this temperature: at +75°C ambient, maximum dissipation drops to ~1.2 W (per DS35366 Fig. 3). Designers must apply RθJA = 62 °C/W or RθJL = 19.4 °C/W based on actual board layout to calculate safe operating limits.
