Product details
Overview
BCP54-16,115 from Nexperia is an AEC-Q101 qualified NPN medium power transistor in SOT223 (SC-73) package, rated for 45 V VCEO, 1 A continuous collector current, and 100–250 DC current gain (hFE) at VCE = 2 V, IC = 150 mA. It serves as a low-side switch or MOSFET driver in automotive power management circuits with thermal resistance as low as 93 K/W when mounted on 6 cm² copper pad.
For engineers reviewing the BCP54-16,115 datasheet, BCP54-16,115 pinout, BCP54-16,115 application, or BCP54-16,115 equivalent, this part is selected for linear voltage regulators, battery-driven devices, and automotive-grade switching where robust junction temperature margin (Tj ≤ 150 °C), pulsed peak current capability (ICM = 2 A), and validated thermal performance on FR4 PCBs are critical.
Technical Context
This transistor operates as a silicon NPN bipolar junction device optimized for medium-power switching and amplification. Its design supports stable DC current gain across IC = 5 mA to 500 mA, with VCE(sat) ≤ 0.5 V at IC = 500 mA / IB = 50 mA and fT = 100–180 MHz under 5 V, 50 mA bias - enabling use in both switching and RF-adjacent signal conditioning.
Thermal behavior is defined by three mounting configurations: standard footprint (Rth(j-a) = 195 K/W), 1 cm² collector pad (125 K/W), and 6 cm² pad (93 K/W). The device's AEC-Q101 qualification confirms reliability under automotive thermal cycling, humidity, and mechanical stress conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in low-side switch designs. |
| IC | 1 A continuous - Sustained load current capability; sets maximum steady-state power stage output. |
| hFE | 100–250 at VCE = 2 V, IC = 150 mA - Predictable current amplification for base drive sizing in linear and switching modes. |
| VCE(sat) | ≤ 0.5 V at IC = 500 mA, IB = 50 mA - Low saturation voltage minimizes conduction loss and self-heating in on-state operation. |
| Ptot | 1.35 W with 6 cm² copper pad - Enables higher power dissipation than standard SOT223 footprints without forced cooling. |
| fT | 100–180 MHz - Supports high-speed switching up to ~100 kHz with minimal phase lag in gate driving applications. |
| Rth(j-a) | 93 K/W (6 cm² pad) - Directly determines junction temperature rise above ambient; critical for thermal margin calculation. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads: pins 1 (B), 2 (C), 3 (E), and 4 (C) - dual collector terminals for enhanced thermal and current handling. The exposed collector tab (pins 2 & 4) connects directly to PCB copper for heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input node; requires current-limited drive (IB ≤ 0.3 A) to avoid damage during switching transients. |
| 2 | Collector | Main high-current output terminal; electrically and thermally connected to pin 4 for parallel current path and improved heatsinking. |
| 3 | Emitter | Reference/return node for collector current; tied to ground or low-side return path in switch configurations. |
| 4 | Collector | Second collector terminal; must be soldered to same net as pin 2 to realize full 1.35 W power rating and 93 K/W thermal resistance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock per JESD22 standards. |
| Three hFE bins | BCP54-16 offers 100–250 hFE, enabling precise base drive design without overdesigning current-limiting resistors. |
| Dual-collector SOT223 | Pins 2 and 4 both connect to collector, reducing effective thermal resistance and increasing current sharing in high-reliability layouts. |
| High ICM | 2 A peak (tp ≤ 1 ms) supports surge currents in motor startup, solenoid actuation, and transient load switching. |
| Low VBE | ≤ 1 V at IC = 500 mA enables compatibility with 3.3 V and 5 V logic-level microcontrollers without level-shifting. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |
|---|---|

IC Role / Device Role / Timing Role: NPN medium-power pass element controlling output voltage via base bias feedback loop.

IC Role / Device Role / Timing Role: Medium-power NPN switch placed between load and ground, activated by microcontroller GPIO. Use Value: Dual-collector thermal design sustains 1 A continuous current without heatsink; AEC-Q101 rating ensures field reliability in harsh environments. |
Use Scenario: Power path control and load switching in portable medical monitors, handheld test equipment, and wireless sensors. IC Role / Device Role / Timing Role: Low-quiescent-current NPN switch managing battery-to-load connection and reverse-polarity protection circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP54-10,115 | hFE = 63–160 (lower mid-range gain); otherwise identical ratings and package. | Suitable where lower base drive sensitivity is acceptable or where tighter hFE tolerance is needed for batch consistency. | Select when designing for worst-case base current margin or when cost optimization favors standard-gain bin. |
| ZTX653STZ | TO-92 package; VCEO = 60 V; IC = 1 A; hFE = 100–300; no AEC-Q101 qualification. | Used in non-automotive consumer or industrial applications requiring higher voltage margin but less thermal performance. | Choose only for through-hole prototyping or legacy board reuse; lacks SOT223 thermal advantages and automotive qualification. |
Compared with BCP54-10,115 and ZTX653STZ, the BCP54-16,115 delivers highest guaranteed hFE in its family and unique dual-collector thermal architecture - making it optimal for automotive low-side switches where gain stability and junction temperature control are design-critical.

FAQ
What is the maximum allowable junction temperature for BCP54-16,115?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation. Derating is required above Tamb = 25 °C - for example, at 100 °C ambient, maximum usable Ptot drops to ~0.7 W with 6 cm² copper pad, based on Rth(j-a) = 93 K/W.
Can BCP54-16,115 replace BCP54-10,115 in existing designs?
Yes - pinout, package, voltage/current ratings, and thermal characteristics are identical. Only hFE differs (100–250 vs. 63–160). If the original design uses conservative base drive (e.g., IB ≥ 5 mA at IC = 150 mA), BCP54-16,115 will operate with higher gain margin and potentially lower base drive loss.
Is the SOT223 footprint for BCP54-16,115 compatible with standard reflow profiles?
Yes - Nexperia specifies JEDEC J-STD-020-compliant reflow profiles for SOT223. Recommended peak temperature is 260 °C for ≤ 30 seconds, with ramp rates ≤ 3 °C/s. The package outline (Fig. 9) and solder land pattern (Fig. 10) are fully documented for IPC-7351B Class B compliance.
Does BCP54-16,115 support pulsed operation beyond its DC ratings?
Yes - it supports ICM = 2 A single-pulse (tp ≤ 1 ms) and IC = 500 mA pulsed (tp ≤ 300 μs, duty cycle ≤ 0.02). These conditions are validated in Table 1 and Table 5; thermal limits still apply - pulse energy must stay within the transient thermal impedance curve (Fig. 4) for the chosen PCB layout.
