Product details
Overview
BCX56-16,115 from Nexperia is an NPN medium-power bipolar junction transistor in SOT89 (SC-62) surface-mount package, rated for 80 V VCEO, 1 A continuous collector current, and DC current gain (hFE) of 100–250 at VCE = 2 V and IC = 150 mA. It serves as a low-side switch or linear regulator pass element in battery-powered industrial power management circuits.
For engineers reviewing the BCX56-16,115 datasheet, BCX56-16,115 pinout, BCX56-16,115 application, or BCX56-16,115 equivalent, this device is selected for medium-current switching where thermal performance on FR4 PCBs with extended collector pad area (up to 6 cm²) enables 1.35 W total power dissipation and stable operation up to 150 °C junction temperature.
Technical Context
This transistor operates in active and saturation regions with verified VCE(sat) ≤ 0.5 V at IC = 500 mA and IB = 50 mA, and exhibits fT = 100–180 MHz under VCE = 5 V, IC = 50 mA conditions. Its pulsed peak collector current rating is 2 A (tp ≤ 1 ms), supporting transient load handling in power control stages.
The device features three hFE bins (BCX56, BCX56-10, BCX56-16); BCX56-16 delivers highest DC gain consistency across IC = 5–500 mA range, with minimum hFE = 100 at 150 mA - optimized for precision current amplification in feedback paths of linear regulators and MOSFET gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - supports operation in 48 V industrial bus and 60 V automotive auxiliary systems without breakdown. |
| IC (continuous) | 1 A - enables direct drive of small solenoids, LED strings, or logic-level MOSFET gates without external buffering. |
| hFE (min @ 150 mA) | 100 - ensures reliable base current design margin for low-power microcontroller GPIO-driven switching. |
| Ptot (6 cm² pad) | 1.35 W - allows sustained 750 mW dissipation at 75 °C ambient when mounted per Fig. 1 (curve 3). |
| Rth(j-a) (6 cm² pad) | 93 K/W - enables thermal design predictability on standard FR4 PCBs without heatsinks. |
| fT | 100–180 MHz - supports high-speed switching in PWM-based amplifier stages up to ~10 MHz fundamental frequency. |
| VBE (max @ 500 mA) | 1 V - simplifies base resistor calculation for TTL/CMOS-compatible drive sources. |
Pinout & Package
SOT89 (SC-62) plastic surface-mount package: 3-pin, 1.5 mm pitch, 4.5 mm × 2.5 mm × 1.5 mm body, with exposed collector tab for thermal conduction to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (E) | Reference node for current return path; tied to ground or low-side rail in common-emitter configurations. |
| 2 | Collector (C) | Main power output terminal; soldered to large copper pour for thermal management and current routing. |
| 3 | Base (B) | Control input requiring current-limited drive; compatible with 3.3 V/5 V MCU outputs via series resistor. |
Key Features
| Feature | Design Value |
|---|---|
| High hFE bin (100–250) | Reduces required base drive current by ≥2× vs. BCX56-10, lowering MCU GPIO loading and PCB trace losses. |
| 80 V VCEO rating | Provides 20 % voltage headroom above 48 V nominal industrial rails, eliminating need for snubbers in inductive load switching. |
| 1.35 W Ptot (6 cm² pad) | Enables single-transistor 1 A switching without heatsink in space-constrained enclosures like DIN-rail power modules. |
| Low VCE(sat) (≤0.5 V) | Minimizes conduction loss to ≤500 mW at full load, improving efficiency in battery-operated linear regulators. |
| SOT89 thermal footprint | Standardized reflow profile compatibility (Fig. 11) ensures manufacturability across contract electronics assembly lines. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |

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 |
|---|---|---|---|
| BCP56-16,115 | Same hFE bin (100–250), but SOT223 package with higher Ptot = 1.5 W and Rth(j-a) = 70 K/W (with 6 cm² pad). | Preferred where board space permits larger footprint and higher thermal margin is needed for 1.2 A continuous loads. | Select BCP56-16 when thermal derating headroom is critical and SOT223 mounting is acceptable. |
| ZTX653STZ | Higher VCEO = 100 V, same IC = 1 A, but hFE = 100–300 and SOT89-3L package identical to BCX56-16. | Used in 72 V telecom power supplies where 80 V margin is insufficient; otherwise pin-identical drop-in replacement. | Choose ZTX653STZ only if system requires >80 V breakdown rating; otherwise BCX56-16 offers tighter hFE distribution. |
Compared with BCX56-16,115, BCP56-16 provides superior thermal performance in larger packages while ZTX653STZ extends voltage capability without altering footprint - both require validation of hFE spread impact on base bias networks.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current (IB) is 0.3 A per Table 5. However, for reliable long-term operation at 1 A collector current, base current should be limited to 50–100 mA to maintain saturation and avoid thermal runaway - confirmed by VCE(sat) test condition in Table 7.
Can BCX56-16,115 replace BCX56-10 in existing designs?
Yes, BCX56-16,115 can directly replace BCX56-10 as it shares identical package, voltage/current ratings, and pinout. The higher minimum hFE (100 vs. 63) reduces required base drive, potentially improving noise immunity and reducing base resistor power dissipation.
What PCB layout practices maximize thermal performance?
Connect Pin 2 (collector) to a ≥6 cm² copper pour on the top layer, using ≥4 thermal vias (0.3 mm diameter) to inner/ground planes. Maintain ≥0.5 mm clearance from other components and avoid solder mask over the collector pad to ensure optimal heat transfer per Figure 1 curve (3).
Is BCX56-16,115 suitable for automotive applications?
No - BCX56-16,115 is not AEC-Q101 qualified and lacks automotive-specific stress testing. Nexperia explicitly states in Section 14 that non-automotive qualified products must not be used in safety-critical or life-support systems; use automotive-grade alternatives like PBSS4041T for such applications.
