Product details
Overview
BC56-16PA,115 from Nexperia is an NPN medium power transistor in a leadless DFN2020-3 (SOT1061) package, rated for 80 V VCEO, 1 A continuous collector current, and 250 hFE at IC = 150 mA / VCE = 2 V. It serves as a low-side switch or MOSFET driver in compact power management circuits with thermal enhancement via exposed collector pad.
For engineers reviewing the BC56-16PA,115 datasheet, BC56-16PA,115 pinout, BC56-16PA,115 application, or BC56-16PA,115 equivalent, key selection criteria include its 100–250 DC current gain range at 150 mA, 500 mV VCE(sat) at 500 mA/50 mA drive, 298 K/W Rth(j-a) on standard FR4, and SOT1061 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a general-purpose NPN bipolar junction transistor optimized for linear and switching applications where medium current handling and stable gain across temperature are required. Its design integrates an exposed collector pad to improve thermal conduction and electrical grounding, enabling reliable operation up to 150 °C junction temperature.
The BC56-16PA variant is specifically binned for hFE = 100–250 at VCE = 2 V and IC = 150 mA under pulsed conditions (tp ≤ 300 μs, duty ≤ 0.02), distinguishing it from BC56-10PA (63–160) and base BC56PA (63–250). It supports fast switching with fT = 100–180 MHz at VCE = 5 V / IC = 50 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in low-side switch or regulator designs. |
| IC (continuous) | 1 A - Continuous collector current rating; supports sustained load switching in battery-powered devices and power management blocks. |
| hFE | 100–250 at VCE = 2 V, IC = 150 mA - Tighter gain bin enables predictable base drive sizing without overdesigning bias networks. |
| VCE(sat) | ≤500 mV at IC = 500 mA, IB = 50 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications. |
| Rth(j-a) | 298 K/W on standard FR4 - Thermal resistance baseline informs heatsinking requirements when operating near 1 W dissipation limits. |
| fT | 100–180 MHz - Transition frequency supports use in high-speed digital switching and RF pre-driver stages up to ~100 MHz. |
| Cc | 6 pF - Collector capacitance impacts switching speed and noise coupling; suitable for <10 MHz switching with minimal Miller effect. |
Pinout & Package
Package: SOT1061 (DFN2020-3), 2.0 × 2.0 × 0.65 mm, leadless, thermally enhanced with exposed collector pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input terminal; requires current-limited drive (max IB = 0.3 A) to avoid saturation delay or thermal stress. |
| 2 | Emitter (E) | Reference node for current flow; connected to ground or low-side return path in common-emitter configurations. |
| 3 | Collector (C) | Power output terminal; electrically and thermally tied to exposed copper pad for efficient heat transfer and low-inductance routing. |
Key Features
| Feature | Design Value |
|---|---|
| Exposed collector pad | Enables direct thermal coupling to PCB copper, reducing Rth(j-a) by up to 60% versus standard SOT packages when using 1 cm² mounting area. |
| Three hFE bins | Allows precise gain matching across production batches-BC56-16PA's 100–250 range supports consistent current amplification in feedback loops. |
| High ICM | 2 A peak collector current (tp ≤ 1 ms) supports short-duration surge handling in motor gate drivers or inrush limiting circuits. |
| Low VBE | ≤1 V at IC = 500 mA - Reduces base drive voltage overhead and simplifies logic-level interfacing with microcontrollers or gate drivers. |
| Ultra-thin profile | 0.65 mm max height enables use in space-constrained portable electronics and stacked PCB assemblies. |
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 SOT1061 package, identical hFE bin (100–250), but rated for 80 V VCEO and 1.5 A IC; higher Ptot (1.65 W on 4-layer PCB). | Higher continuous current and power dissipation support heavier loads in industrial controls where thermal margin is critical. | Select BCP56-16,115 if system requires >1 A steady-state current or extended thermal endurance beyond 1 W. |
| BC817-40,215 | SOT23 package, lower VCEO (45 V), same hFE range (250–630), but only 0.5 A IC; no exposed pad, higher Rth(j-a) (~300 K/W). | Limited to low-voltage consumer electronics; unsuitable for 24 V+ systems or high-pulse-current loads due to package and rating constraints. | Choose BC817-40,215 only for cost-sensitive, low-power signal switching where board space and thermal performance are secondary. |
Compared with BC56-16PA,115, BCP56-16,115 offers higher current and thermal capability in identical packaging, while BC817-40,215 trades voltage/current headroom and thermal performance for lower cost and smaller footprint in non-demanding applications.

FAQ
What is the maximum allowable junction temperature for BC56-16PA,115?
The absolute maximum junction temperature (Tj) is 150 °C per the datasheet Limiting Values table. Operation above this threshold risks permanent degradation of hFE, increased leakage, or bond wire failure. Derating curves in Figure 1 confirm power dissipation must be reduced linearly above 25 °C ambient to maintain Tj ≤ 150 °C.
Does BC56-16PA,115 support automotive applications?
No. The BC56PA series is explicitly marked as non-automotive qualified in the Revision History section (v.11, July 2023). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia recommends its -Q qualified alternatives such as the BCP56-16Q series.
How does the exposed collector pad affect PCB layout?
The exposed collector pad (Pin 3) must be connected to a dedicated copper pour on the PCB for optimal thermal and electrical performance. Recommended footprint per Figure 12 uses a 1.05 × 1.05 mm solder land with 0.25 mm solder mask opening. Thermal vias under the pad significantly reduce Rth(j-a), especially on multilayer boards.
Can BC56-16PA,115 replace BC547 or BC337 in existing designs?
Not directly. BC547 (TO-92) and BC337 (SOT23) differ in package, pinout, voltage rating (45–50 V), and thermal behavior. BC56-16PA,115 has higher VCEO (80 V), higher IC (1 A vs. 100–500 mA), and requires re-layout for SOT1061. Electrical substitution demands verification of gain matching, saturation voltage, and thermal margins in the target application.
