Product details
Overview
BCP 54-16 E6327 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for audio-frequency driver and output stages in linear and switching applications. It features a 45 V VCEO, 1 A continuous collector current, 0.5 V typical VCE(sat) at IC = 500 mA / IB = 50 mA, hFE of 100–250 (at IC = 150 mA), and SOT223 surface-mount package with four terminals (B-C-E-C).
For engineers reviewing the BCP 54-16 E6327 datasheet, BCP 54-16 E6327 pinout, BCP 54-16 E6327 application, or BCP 54-16 E6327 equivalent, this part supports high-current AF amplification, low-saturation switching in power management blocks, and complementary PNP pairing with BCP51–BCP53 series in push-pull topologies.
Technical Context
This transistor operates as a medium-power general-purpose NPN device optimized for audio-frequency signal amplification and switching. Its dual-collector configuration (Pin 2 and Pin 4 both connected to collector) enhances thermal dissipation and current handling in SOT223 footprint, while its hFE range (100–250 at IC = 150 mA) ensures stable DC biasing across production lots.
The device meets AEC-Q101 qualification for automotive-grade reliability and exhibits low VCE(sat) (≤0.5 V) and high fT (100 MHz typ.), enabling use in Class AB amplifier stages and fast-switching load drivers up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown under open-base condition; sets upper rail limit for single-supply AF output stages. |
| IC (cont.) | 1 A - Continuous collector current rating; supports ≥1 W dissipation in TO-223-equivalent thermal path with PCB copper heatsinking. |
| VCE(sat) | 0.5 V max @ IC = 500 mA, IB = 50 mA - Low saturation voltage reduces conduction loss in switching regulators and emitter-follower buffers. |
| hFE | 100–250 @ IC = 150 mA, VCE = 2 V - Wide DC current gain range enables robust bias design without tight resistor tolerance requirements. |
| fT | 100 MHz typ. @ IC = 50 mA, VCE = 10 V - Sufficient gain-bandwidth for audio preamp and wideband driver stages up to 10 MHz. |
| Ptot | 2 W @ TS ≤ 120°C - Total power dissipation capability with solder-point thermal resistance ≤15 K/W; requires minimum 25 mm² 2-oz copper pad. |
| RthJS | ≤15 K/W - Junction-to-solder-point thermal resistance; defines thermal interface requirement for reliable 1 A operation on standard FR4 PCBs. |
Pinout & Package
SOT223 package with 4-terminal configuration: thermally enhanced leadframe, exposed collector tab (Pins 2 & 4), and standardized footprint per Infineon outline drawing (6.5 × 3.5 × 1.75 mm, 1.6 mm height). Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector (dual-collector layout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Base | Control terminal for forward-biased junction; requires current-limited drive (max IB = 100 mA DC) to avoid secondary breakdown. |
| Pin 2 | Collector | Main collector connection; electrically tied to Pin 4; serves as primary high-current output node and thermal path to PCB copper. |
| Pin 3 | Emitter | Reference terminal for bias network; must be routed with low-inductance path to ground plane in switching applications. |
| Pin 4 | Collector | Secondary collector terminal; parallel-connected to Pin 2 to reduce bond-wire resistance and improve thermal spreading in SOT223 body. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive ambient temperature range (−40°C to +150°C junction) and mechanical stress testing per JEDEC standards. |
| Dual-collector SOT223 | Two collector pins (2 & 4) reduce current density and thermal resistance by ~20% vs. single-collector equivalents. |
| Low VCE(sat) | 0.5 V max at rated IC/IB enables >90% efficiency in 12 V linear regulators and audio output stages. |
| High hFE range | 100–250 at 150 mA allows single-resistor base bias in fixed-gain amplifier designs without feedback trimming. |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C, 10 s max). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP54-10 E6327 | Same package and pinout; hFE bin 63–100 (vs. 100–250 for -16); lower gain consistency at high IC. | Preferred for cost-sensitive consumer audio where tighter hFE spread is unnecessary. | Select when gain variation <±20% is acceptable and BOM cost reduction is prioritized over bias stability. |
| MJD112-1G | TO-252 package; higher VCEO (80 V); hFE 1000–2000 at 150 mA; no dual-collector layout. | Used in higher-voltage industrial motor control where SOT223 thermal limits are exceeded. | Choose only if board space permits TO-252 and system requires >45 V blocking or ultra-high hFE for Darlington configurations. |
Compared with BCP54-10 E6327 and MJD112-1G, the BCP54-16 E6327 offers superior hFE consistency for precision biasing and optimized thermal performance in SOT223 footprint-making it ideal for automotive and industrial applications demanding both reliability and compactness.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature (Tj) is 150°C, as specified in the Infineon datasheet. Operation above this limit risks permanent degradation of hFE and increased leakage. Derating is required above TS = 120°C, where total power dissipation drops linearly to zero at 150°C case temperature.
Is BCP 54-16 E6327 pin-compatible with BCP54-10 E6327?
Yes-both share identical SOT223 package, pin numbering (1=B, 2=C, 3=E, 4=C), and mechanical footprint. The only difference is hFE binning: -16 denotes 100–250, while -10 specifies 63–100. No PCB redesign is needed for substitution, though bias networks may require verification.
Does this transistor support pulsed operation beyond its DC ratings?
Yes-per the datasheet, peak collector current (ICM) is 1.5 A for pulses ≤10 ms, and permissible pulse load ratio (Ptot(max)/Ptot(DC)) reaches 10× at tp = 100 µs (D = 0.01). Thermal design must account for transient junction temperature rise using RthJS curves.
How does the dual-collector configuration affect PCB layout?
The dual-collector (Pins 2 & 4) must be routed to the same net-typically the high-current output or supply rail. Both pins should connect to a shared copper pour ≥25 mm² with multiple thermal vias to inner ground/power planes to maximize heat extraction and minimize inductance in switching paths.
