Product details
Overview
BCP 68-25 E6327 from Infineon Technologies is an NPN silicon audio-frequency transistor in SOT223 package, rated for 1 A continuous collector current, 20 V VCEO, and 3 W total power dissipation at TS ≤ 114 °C; used in low-voltage switching and linear amplification stages of automotive body control modules and industrial sensor signal conditioning circuits.
For engineers reviewing the BCP 68-25 E6327 datasheet, BCP 68-25 E6327 pinout, BCP 68-25 E6327 application, or BCP 68-25 E6327 equivalent, key selection criteria include DC current gain (hFE = 50–375 at IC = 5 mA to 1 A), VCE(sat) ≤ 0.5 V at IC = 1 A / IB = 100 mA, thermal resistance RthJS ≤ 12 K/W, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This NPN bipolar junction transistor operates in active, saturation, and cutoff regions with defined breakdown limits: V(BR)CEO = 20 V (IC = 30 mA), V(BR)CBO = 25 V (IC = 10 µA), and V(BR)EBO = 5 V (IE = 10 µA). Its fT = 100 MHz at IC = 100 mA enables stable operation up to mid-audio frequencies.
The device features complementary pairing with BCP69 (PNP), supports pulse operation up to ICM = 2 A (tp ≤ 10 ms), and maintains hFE stability across −50 °C to +150 °C junction temperature range, validated per AEC-Q101 stress testing protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit in low-side switch designs. |
| IC | 1 A - Continuous DC collector current rating; supports driving 12 V solenoids or relay coils directly. |
| hFE | 50–375 - DC current gain range across 5 mA–1 A; enables single-stage amplification with predictable biasing. |
| VCE(sat) | ≤ 0.5 V @ IC=1 A/IB=100 mA - Low saturation voltage reduces conduction loss in switching applications. |
| RthJS | ≤ 12 K/W - Junction-to-solder-point thermal resistance; allows 3 W power dissipation with ≤36 K temperature rise above PCB copper. |
| fT | 100 MHz - Transition frequency at IC=100 mA/VCE=5 V; ensures adequate bandwidth for audio preamp and PWM gate drive buffering. |
| Tj | 150 °C - Maximum junction temperature; enables operation in under-hood automotive environments without derating below 125 °C ambient. |
Pinout & Package
SOT223 package with 4-terminal configuration: three leads plus exposed thermal pad (pin 4 = collector, shared with pin 2); thermally enhanced for high-power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires ≥100 mA peak base drive for full saturation at 1 A collector load. |
| 2 | Collector | Main current output path; electrically connected to thermal pad (pin 4) for low-impedance heat transfer to PCB. |
| 3 | Emitter | Reference terminal for bias network; tied to ground or low-side return path in common-emitter configurations. |
| 4 | Collector (thermal pad) | Exposed copper pad soldered to PCB copper pour; mandatory for achieving RthJS ≤ 12 K/W and full 3 W rating. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, HTRB, and ESD-HBM ≥ 2 kV. |
| Low VCE(sat) | ≤ 0.5 V at rated 1 A load ensures < 0.5 W conduction loss, critical for thermally constrained PCBs. |
| High hFE consistency | Min 50 at IC = 5 mA and min 60 at IC = 1 A enables stable bias design across production lots. |
| Thermally robust SOT223 | Exposed collector pad delivers 3× better thermal performance than standard SOT23, enabling higher current density. |
| Complementary PNP pair | BCP69 available as matched PNP counterpart for push-pull output stages and H-bridge drivers. |
Applications
| Automotive Door Module Driver | Industrial Proximity Sensor Amplifier |
|---|---|
Use Scenario: Driving 12 V window lift motor via microcontroller GPIO through discrete level-shifting stage. IC Role / Device Role / Timing Role: NPN switch providing low-side current sink with fast turn-on/turn-off for PWM-controlled motor direction. Use Value: VCE(sat) ≤ 0.5 V minimizes self-heating during 1 A stall current, while AEC-Q101 compliance ensures 15-year field reliability. | Use Scenario: Amplifying weak analog output (0.5–2 V) from inductive proximity sensor before ADC sampling. IC Role / Device Role / Timing Role: Common-emitter DC amplifier with fixed bias network delivering 20 dB voltage gain at audio frequencies. Use Value: hFE ≥ 160 at IC = 500 mA ensures stable gain over temperature, reducing calibration drift in factory automation systems. |
| LED Signage Power Switch | DC-DC Converter Pre-regulator |
Use Scenario: Switching 24 V, 800 mA LED string in outdoor digital signage with ambient temperatures up to 85 °C. IC Role / Device Role / Timing Role: High-current saturated switch controlled by MCU PWM signal at 1–5 kHz. Use Value: 3 W power rating with RthJS ≤ 12 K/W allows direct mounting on 2 oz copper without heatsink, cutting BOM cost. | Use Scenario: Linear pre-regulation stage stepping down 48 V bus to 12 V before buck converter input in telecom power supply. IC Role / Device Role / Timing Role: Emitter-follower pass transistor dissipating up to 2.5 W continuously under load transients. Use Value: Tj = 150 °C rating permits operation at full load in sealed enclosures without forced air cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching and amplification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP56-16 E6327 | Lower IC = 1 A (same), but hFE min = 100 @ IC = 150 mA; VCE(sat) = 0.7 V @ IC = 500 mA - higher conduction loss. | Less suitable for 1 A saturated switching; better for medium-gain linear amplification where tighter hFE tolerance matters. | Select when gain consistency > 100 at mid-current is prioritized over low-loss switching. |
| ZTX653 | Higher VCEO = 60 V, same SOT223 package; hFE = 100–800, but no AEC-Q101 qualification. | Acceptable for industrial non-automotive use; unsuitable for automotive ECUs requiring qualification evidence. | Choose only for non-automotive applications needing higher voltage headroom and wider gain spread. |
Compared with BCP68-25 E6327, BCP56-16 offers tighter hFE control at lower current but sacrifices saturation efficiency, while ZTX653 provides higher voltage capability and broader gain range at the cost of automotive qualification - making BCP68-25 the optimal balance for AEC-Q101-compliant 20 V, 1 A switching.

FAQ
Is BCP 68-25 E6327 RoHS compliant and lead-free?
Yes, BCP 68-25 E6327 is Pb-free and fully compliant with RoHS Directive 2011/65/EU. The SOT223 package uses lead-free solderable terminations and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for surface-mount assembly.
What is the maximum allowable PCB copper area for thermal pad (pin 4)?
The thermal pad (pin 4) must be soldered to a minimum 100 mm² copper pour on the top layer, connected via ≥4 thermal vias (0.3 mm diameter) to internal ground plane. This achieves the specified RthJS ≤ 12 K/W and enables full 3 W power dissipation at TS = 114 °C.
Can BCP 68-25 E6327 replace BC847 in a 5 V logic interface?
No - BC847 is an SOT23 NPN with IC = 100 mA and VCEO = 45 V, optimized for small-signal switching. BCP68-25 is a high-current SOT223 device (IC = 1 A, VCEO = 20 V) with different gain profile and thermal requirements; substitution would require PCB layout redesign and bias recalculation.
Does Infineon provide SPICE models for BCP 68-25 E6327?
Yes, Infineon publishes a verified bipolar transistor SPICE model (BCP68-25.lib) on its official website, covering DC, AC, and transient behavior across −55 °C to +150 °C, including thermal coupling and parasitic capacitances extracted from characterization data.
