Product details
Overview
BCP5416H6327XTSA1 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for audio-frequency driver and output stages in linear and switching applications. It delivers 1 A continuous collector current, 45 V VCEO, 0.5 V VCE(sat) at IC = 500 mA / IB = 50 mA, and 100 MHz fT, enabling high-efficiency amplification in automotive audio power stages.
For engineers reviewing the BCP5416H6327XTSA1 datasheet, BCP5416H6327XTSA1 pinout, BCP5416H6327XTSA1 application, or BCP5416H6327XTSA1 equivalent, key selection criteria include its SOT223 package thermal resistance (RthJS ≤ 15 K/W), AEC-Q101 qualification, complementary PNP pairing with BCP51–BCP53 series, and low-saturation performance under 500 mA load conditions.
Technical Context
This transistor operates as a medium-power general-purpose NPN switch/amplifier with DC current gain (hFE) ranging from 63 to 100 at IC = 150 mA and 25–250 at IC = 500 mA. Its VCE(sat) ≤ 0.5 V ensures minimal conduction loss in Class-AB audio output stages and relay drivers.
The device features a robust thermal design with 2 W total power dissipation at TS ≤ 120°C and junction temperature rating up to 150°C. Its 45 V VCEO and 45 V VCBO support operation in 24 V automotive supply rails with margin for transient spikes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Supports 24 V automotive systems with ≥2× transient headroom |
| IC (continuous) | 1 A - Enables direct drive of mid-power loads like small relays or speaker outputs |
| VCE(sat) | ≤ 0.5 V @ IC = 500 mA, IB = 50 mA - Reduces heat generation in linear output stages |
| hFE | 63–100 @ IC = 150 mA - Ensures stable biasing in fixed-gain amplifier designs |
| fT | 100 MHz - Sufficient for AF bandwidth extension and fast-switching control loops |
| RthJS | ≤ 15 K/W - Allows direct PCB copper pour heatsinking without external heatsink |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive under-hood use |
Pinout & Package
BCP5416H6327XTSA1 is housed in a surface-mount SOT223 package with four terminals: emitter (pin 3), base (pin 1), collector (pins 2 and 4 tied internally). The package supports high thermal conductivity via the exposed collector tab soldered to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Base | Control input; requires current-limited drive to achieve hFE-based gain |
| Pin 2 | Collector | Main power output node; electrically connected to Pin 4 and thermal pad |
| Pin 3 | Emitter | Reference/return path; common connection for bias network and load return |
| Pin 4 | Collector (tab) | Thermal and electrical extension of collector; must be soldered to ≥2 cm² copper area |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 0.5 V max at 500 mA enables <1 W conduction loss in 12 V relay drivers |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (−40°C to +150°C) and mechanical shock |
| Complementary PNP pairing | Direct match with BCP51–BCP53 series for push-pull output stage implementation |
| SOT223 thermal performance | RthJS ≤ 15 K/W allows 1.5 W continuous dissipation with 2-layer 2 oz Cu PCB |

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 |
|---|---|---|---|
| BCP54T-7-F (Diodes Inc.) | VCEO = 45 V, IC = 1 A, but hFE min = 40 @ 150 mA (vs. 63 for BCP5416) | Lower gain may require larger base drive in low-voltage control circuits | Preferred where cost sensitivity outweighs gain consistency needs |
| MJD112G (ON Semiconductor) | VCEO = 80 V, IC = 2 A, but SOT-223 variant has RthJS = 20 K/W (vs. ≤15 K/W) | Higher voltage rating suits 48 V industrial systems, but thermal derating required above 1.2 W | Chosen when system-level overvoltage protection exceeds 45 V requirement |
Compared with BCP54T-7-F and MJD112G, BCP5416H6327XTSA1 offers superior thermal efficiency (RthJS ≤ 15 K/W) and tighter hFE distribution-critical for production-matched audio output stages and AEC-Q101-compliant automotive modules.

FAQ
Is BCP5416H6327XTSA1 pin-compatible with BCP54-16?
Yes. BCP5416H6327XTSA1 uses the same SOT223 package with identical pin 1 (base), pin 2 (collector), pin 3 (emitter), and pin 4 (collector tab) configuration as BCP54-16. The "H6327XTSA1" suffix denotes Infineon's tape-and-reel packaging standard (7-inch reel, 1000 pcs), not a functional or pinout change.
What is the maximum safe operating current at 100°C case temperature?
At TS = 100°C, the device's power derating curve limits Ptot to ~1.4 W. With VCE(sat) ≈ 0.45 V at IC = 500 mA, maximum continuous IC remains 1 A-but practical safe current is ~900 mA to maintain junction temperature below 150°C under worst-case thermal resistance.
Does this transistor require a base resistor in switching applications?
Yes. To ensure saturation and avoid secondary breakdown, a base resistor must limit IB to ≥ IC/hFE(min). For 500 mA load and hFE ≥ 63, minimum IB = 7.9 mA. With 3.3 V MCU GPIO, a 330 Ω resistor provides ~9 mA drive, satisfying this requirement.
Can BCP5416H6327XTSA1 replace BC847 in a small-signal amplifier?
No. BC847 is a low-power SOT23 transistor (IC = 100 mA, Ptot = 310 mW); BCP5416H6327XTSA1 is a medium-power SOT223 device (IC = 1 A, Ptot = 2 W). Substituting it introduces unnecessary thermal mass, layout mismatch, and potential instability due to higher capacitance and slower turn-off in small-signal nodes.
