Product details
Overview
BCP5116TA from Diodes Incorporated is a PNP medium-power transistor in SOT223 package, rated for -45 V VCEO, -1 A continuous collector current, and 2 W power dissipation. It features low saturation voltage (VCE(sat) ≤ -500 mV @ -500 mA), hFE gain group 16 (100–250), and AEC-Q101 qualification for automotive reliability. It serves as a switching or linear amplifier in medium-power load control circuits.
For engineers reviewing the BCP5116TA datasheet, BCP5116TA pinout, BCP5116TA application, or BCP5116TA equivalent, key selection criteria include verified VCEO rating, gain group consistency at IC = -150 mA, thermal resistance (RθJL = 19.4 °C/W), and SOT223 mounting compatibility with 50 mm × 50 mm 1 oz copper PCBs.
Technical Context
This PNP bipolar junction transistor operates in active or saturation mode for DC and low-frequency switching up to ~150 MHz fT. Its design supports stable current amplification across -55°C to +150°C ambient range, with guaranteed hFE ≥ 100 at IC = -150 mA and VCE = -2 V.
The device uses a planar epitaxial structure with low RθJL (19.4 °C/W) and high ESD robustness (HBM 4 kV), enabling reliable operation in automotive body electronics and industrial power stages where thermal management and transient immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -45 V - Maximum safe collector-emitter voltage before breakdown under open-base conditions. |
| IC (cont) | -1 A - Continuous DC collector current capability without derating at TA = 25°C. |
| PD | 2 W - Max steady-state power dissipation on 50 mm × 50 mm 1 oz Cu PCB under still air. |
| VCE(sat) | ≤ -500 mV @ IC = -500 mA, IB = -50 mA - Ensures low conduction loss in saturated switch applications. |
| hFE (gain group 16) | 100–250 @ IC = -150 mA, VCE = -2 V - Predictable current gain for biasing stability in amplifier or driver stages. |
| fT | 150 MHz - Supports audio-frequency amplification and fast switching up to ~100 kHz with margin. |
| RθJL | 19.4 °C/W - Low junction-to-lead thermal resistance enables efficient heat transfer to PCB copper pour. |
Pinout & Package
SOT223 package with molded green plastic case (UL 94V-0), matte tin-plated leads, and 0.112 g mass. Collector lead is electrically and thermally connected to the large central tab for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Main current exit path; connects to ground or low-side reference in PNP switch configurations. |
| 2 (Base) | B | Control terminal requiring negative bias current relative to emitter to turn on device. |
| 3 (Collector) | C | Main current entry point; soldered to large copper area for thermal and electrical return path. |
| Tab (Collector) | C (common with Pin 3) | Integral thermal and electrical connection to PCB copper; must be soldered for rated power handling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including temperature cycling, HTRB, and ESD stress per JESD22. |
| Gain group 16 (hFE = 100–250) | Enables consistent bias design across production lots without recalibration in linear amplifier stages. |
| VCE(sat) ≤ -500 mV @ -500 mA | Reduces power loss by >30% vs. typical PNP transistors at same current, improving efficiency in 12 V load switches. |
| RθJL = 19.4 °C/W | Allows 1.2 W continuous dissipation at TA = 70°C with standard layout-no heatsink required. |
| Halogen- and antimony-free "Green" construction | Meets IPC-1752A material declaration requirements and EU RoHS 2 (2011/65/EU) compliance. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP5110TA | hFE gain group 10 (63–160) instead of 16; otherwise identical ratings and package. | Lower gain reduces base drive sensitivity but increases tolerance to hFE variation in high-volume production. | Select when tighter hFE distribution is needed for simplified bias network design. |
| BCP5216TA | VCEO = -60 V (vs. -45 V); all other specs match BCP5116TA including hFE group 16 and SOT223 package. | Supports higher bus voltages in 24 V industrial systems where transient spikes exceed 45 V. | Choose for 24 V systems requiring margin against load-dump transients up to 60 V. |
Compared with BCP5116TA, BCP5110TA offers lower gain consistency for cost-sensitive biasing, while BCP5216TA extends voltage headroom for 24 V industrial use-neither requires PCB redesign due to shared SOT223 footprint and pinout.

FAQ
What is the maximum allowable junction temperature for BCP5116TA?
The absolute maximum junction temperature is +150°C, with continuous operation supported from -65°C to +150°C ambient. Derating begins above +25°C at 16.1 mW/°C (based on RθJA = 62 °C/W), and full 2 W power is only sustainable at TA ≤ 25°C on specified PCB layout.
Is BCP5116TA pin-compatible with BCP5216TA and BCP5316TA?
Yes-BCP5116TA, BCP5216TA, and BCP5316TA share identical SOT223 package dimensions, pinout (E-B-C-tab), and mechanical mounting requirements. Only VCEO differs (-45 V, -60 V, -80 V respectively); all other electrical and thermal specs are identical.
Does BCP5116TA require a heatsink in standard applications?
No heatsink is required when mounted on a 50 mm × 50 mm 1 oz copper PCB per datasheet test condition. At 1 W dissipation and TA = 70°C, junction temperature remains below 100°C using only the SOT223 tab soldered to copper, satisfying most automotive and industrial thermal budgets.
How does the gain group 16 specification affect circuit design?
Gain group 16 guarantees hFE between 100 and 250 at IC = -150 mA and VCE = -2 V, enabling deterministic base resistor calculation for saturation switching. Designers can size RB to deliver ≥5 mA base current for reliable turn-on at worst-case hFE = 100, avoiding marginal conduction.
