Product details
Overview
BCP68E6327 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for general audio-frequency amplification and switching applications. It delivers 1 A DC collector current, 25 V VCEO, 0.5 V VCE(sat) at 1 A/100 mA drive, and fT = 100 MHz - enabling use in low-voltage power switching stages of consumer audio amplifiers and LED driver circuits.
For engineers reviewing the BCP68E6327 datasheet, BCP68E6327 pinout, BCP68E6327 application, or BCP68E6327 equivalent, key selection criteria include its SOT-223 package thermal resistance (RthJS ≤17 K/W), high hFE (85–375 at 500 mA), and complementary pairing with BCP69 for push-pull output stages.
Technical Context
This NPN transistor operates as a medium-power linear amplifier or saturated switch in DC-coupled AF stages. Its VCEO = 20 V and VCES = 25 V support operation in 12–15 V rail systems, while low VCE(sat) ≤ 0.5 V at IC = 1 A / IB = 100 mA minimizes conduction loss in Class-A/B output stages.
The device exhibits strong current gain linearity: hFE = 85–375 at IC = 500 mA, VCE = 1 V, and maintains usable gain (hFE ≥ 60) even at full 1 A load - critical for stable biasing in discrete emitter-follower buffers and relay drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - supports operation in 12–15 V supply rails without breakdown risk |
| IC (DC) | 1 A - enables direct driving of small solenoids, LEDs, or pre-driver stages |
| VCE(sat) | ≤ 0.5 V at IC = 1 A / IB = 100 mA - reduces power dissipation in saturated switching mode |
| hFE | 85–375 at IC = 500 mA - ensures robust base drive margin across production lots |
| fT | 100 MHz - sufficient for audio-band amplification and fast-switching control signals |
| RthJS | ≤17 K/W - allows 1.5 W total dissipation with 124 °C case temperature, supporting compact heatsinking |
Pinout & Package
Package: SOT-223 (standardized 4-pin surface-mount outline with exposed collector tab for thermal conduction).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Reference node for bias network; connected to ground or negative rail in common-emitter configurations |
| 2 (Collector) | C | Main current output path; electrically tied to exposed metal tab for thermal and electrical connection to PCB copper pour |
| 3 (Base) | B | Control input; requires ~100 mA peak drive for full saturation at 1 A load |
| 4 (Collector) | C | Duplicate collector terminal - shares same internal node as Pin 2, improves current handling and thermal spreading |
Key Features
| Feature | Design Value |
|---|---|
| Complementary PNP pair | BCP69 - enables matched push-pull output stages with consistent thermal tracking |
| High hFE at high current | hFE ≥ 60 at IC = 1 A - simplifies base drive design and reduces required base current |
| Low VCE(sat) | ≤ 0.5 V - limits power loss to ≤500 mW at 1 A, easing thermal management |
| SOT-223 thermal performance | RthJS ≤17 K/W - permits 1.5 W dissipation with minimal heatsink area on standard FR-4 |
Applications
| Audio Power Amplifier Output Stage | LED Constant-Current Driver |
|---|---|
Use Scenario: Discrete Class-AB output stage in portable stereo amplifiers with ±12 V supplies. IC Role / Device Role / Timing Role: NPN emitter-follower buffer delivering up to 1 A peak current to 4 Ω speaker loads. Use Value: Low VCE(sat) and high hFE reduce crossover distortion and improve efficiency over 1 W output range. | Use Scenario: Linear constant-current sink for high-brightness white LEDs in automotive interior lighting. IC Role / Device Role / Timing Role: Current-regulating pass element controlled by op-amp feedback loop. Use Value: Stable hFE across temperature ensures <±5% current drift from –40 °C to +125 °C ambient. |
| Relay and Solenoid Driver | DC Motor Speed Control (Low-Power) |
Use Scenario: Interface between microcontroller GPIO and 12 V/500 mA automotive relay coil. IC Role / Device Role / Timing Role: Saturated switch providing low-impedance path to ground for relay activation. Use Value: Fast turn-on/off (enabled by fT = 100 MHz) prevents contact chatter during PWM-driven coil energization. | Use Scenario: H-bridge half-bridge element controlling bidirectional 12 V/300 mA brushed DC motor in robotics actuators. IC Role / Device Role / Timing Role: High-side or low-side switching transistor in discrete half-bridge topology. Use Value: Dual collector pins (Pins 2 & 4) lower effective RDS(on)-equivalent resistance, reducing conduction loss during 100% duty cycle operation. |
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 |
|---|---|---|---|
| BCP56-10 | Lower IC = 1 A (same), but hFE = 63–160 at 500 mA - narrower gain spread | Less suitable for high-gain feedback loops requiring wide hFE tolerance | Prefer when tighter hFE binning is needed and fT > 80 MHz is not required |
| MJD112 | Higher VCEO = 80 V, but larger TO-252 package and RthJS = 30 K/W - worse thermal performance | Used where higher voltage margin is mandatory, but board space and thermal budget allow larger footprint | Choose only if system requires >25 V blocking capability; otherwise BCP68E6327 offers superior power density |
Compared with BCP56-10, BCP68E6327 provides broader hFE range for robust biasing across temperature, and compared with MJD112, it delivers 1.8× better thermal resistance in 40% less PCB area - making it optimal for space-constrained 12 V industrial controls.

FAQ
What is the maximum continuous collector current rating for BCP68E6327?
The absolute maximum DC collector current is 1 A at TS = 124 °C, with peak pulsed current rated at 2 A. Derating applies above 25 °C ambient: at 100 °C case temperature, maximum continuous IC drops to approximately 0.65 A per the Ptot vs. TS curve in the datasheet.
Is BCP68E6327 pin-compatible with other SOT-223 transistors like MMBT4401?
No - BCP68E6327 uses a 4-pin SOT-223 configuration with dual collector terminals (Pins 2 and 4), whereas MMBT4401 is a 3-pin SOT-23 device. Physical layout, pin assignment, and thermal pad connectivity differ fundamentally; direct replacement requires PCB redesign.
Does BCP68E6327 require a heatsink in typical 1 A switching applications?
A dedicated heatsink is not required if PCB copper area ≥ 250 mm² is used under the exposed collector tab. With RthJS ≤17 K/W and Ptot = 1.5 W, junction-to-ambient rise is ~60 K under those conditions - staying within the 150 °C Tj limit at 85 °C ambient.
Can BCP68E6327 be used in linear regulator pass transistor applications?
Yes - its low VCE(sat) and stable hFE support use as a series pass element in adjustable linear regulators up to 1 A load. However, safe operating area (SOA) must be verified at target dropout voltage and ambient temperature, especially under transient overload conditions.
