Product details
Overview
BCP 68-25 H6327 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for general audio-frequency amplification and switching applications. It delivers 1 A continuous collector current, 25 V VCEO, 375 minimum hFE at 1 A/1 V, and 0.5 V VCE(sat) at IC = 1 A / IB = 100 mA - enabling high-efficiency low-voltage power stage control in automotive body electronics.
For engineers reviewing the BCP 68-25 H6327 datasheet, BCP 68-25 H6327 pinout, BCP 68-25 H6327 application, or BCP 68-25 H6327 equivalent, key selection criteria include its SOT223 package thermal resistance (RthJS ≤ 12 K/W), AEC-Q101 qualification, complementary pairing with BCP69, and verified performance across –50 °C to 150 °C junction temperature range.
Technical Context
This NPN transistor operates in linear and saturated switching modes with DC current gain (hFE) ranging from 50 (min) at 5 mA to 375 (max) at 1 A, supporting wide dynamic load handling. Its 100 MHz fT at IC = 100 mA / VCE = 5 V enables stable operation up to mid-AF frequencies without phase inversion or gain collapse.
The device features a low 0.5 V collector-emitter saturation voltage at full-rated 1 A collector current and 100 mA base drive, minimizing conduction loss in discrete driver stages. Its VCEO = 20 V and VCES = 25 V ratings support robust operation under transient overvoltage conditions common in 12 V automotive supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit for 12 V automotive switch designs |
| IC (continuous) | 1 A - Continuous collector current rating; supports direct driving of small solenoids, LED arrays, or fan motors |
| hFE @ 1 A | 60–375 - Wide DC current gain spread at full load; enables predictable base drive sizing for worst-case saturation margin |
| VCE(sat) @ 1 A | ≤ 0.5 V - Low saturation voltage reduces power dissipation to ≤500 mW at 1 A, easing thermal design in SOT223 |
| fT | 100 MHz - Transition frequency confirms usable bandwidth beyond 20 kHz audio range; suitable for PWM-driven analog stages |
| RthJS | ≤ 12 K/W - Junction-to-solder-point thermal resistance allows 3 W total dissipation with ≤36 °C temperature rise above PCB copper |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronic components including temperature cycling and HTRB |
Pinout & Package
SOT223 package with exposed collector tab for enhanced thermal conduction and mechanical stability on PCB. Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector (dual-collector configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Base | Current-controlled input node; requires ≥100 mA peak drive for guaranteed 1 A saturation under worst-case hFE |
| Pin 2 | Collector | Main high-current output terminal; electrically tied to Pin 4 and thermal pad for low-inductance, low-resistance path |
| Pin 3 | Emitter | Reference node for biasing; must be connected directly to ground plane to maintain VBE stability and minimize noise coupling |
| Pin 4 | Collector (redundant) | Second collector connection reinforcing thermal and current-carrying capacity; not isolated from Pin 2 |
Key Features
| Feature | Design Value |
|---|---|
| High current gain at full load | hFE ≥ 60 at IC = 1 A / VCE = 1 V - ensures reliable saturation with modest base drive in space-constrained layouts |
| Low VCE(sat) | ≤ 0.5 V at IC = 1 A / IB = 100 mA - cuts conduction loss by >40% vs. standard general-purpose transistors at same current |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (–40 °C to +125 °C case) and lifetime reliability per JEDEC JESD47 |
| Complementary PNP pair | BCP69 available with matched VCEO, IC, and hFE specs - enables balanced push-pull output stages without gain skew |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles up to 260 °C peak |
Applications
| Automotive Door Module Driver | Industrial Fan Speed Control |

IC Role / Device Role / Timing Role: Discrete NPN switch controlling 12 V DC motor direction and stall protection via current-sense feedback. Use Value: 1 A rating and 0.5 V VCE(sat) enable direct motor drive without external MOSFETs, reducing BOM count and PCB area. | Use Scenario: Regulating airflow in HVAC blowers using PWM-modulated base drive. IC Role / Device Role / Timing Role: Linear-mode amplifier stage converting 0–5 V control signal into proportional 0–1 A motor current.

IC Role / Device Role / Timing Role: High-side or low-side current switch operating in saturation mode with microcontroller GPIO interface. Use Value: Dual-collector SOT223 layout provides low thermal impedance, sustaining 1 A pulsed loads without derating at 85 °C ambient. | Use Scenario: Pre-regulating unregulated 24 V input before LDO or buck converter in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Discrete pass transistor in series with feedback network to reduce input-to-output differential voltage. Use Value: 25 V VCES and 3 W Ptot allow safe operation at 15 V drop × 1 A = 15 W dissipation when heatsinked to PCB copper. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP56-16 H6327 | Lower IC (0.5 A), higher hFE (100–250), same SOT223 package | Not suitable for 1 A continuous loads; better for low-power signal amplification | Select only if base drive is limited and load current stays below 500 mA |
| ZTX851 | TO-92 package, IC = 1 A, VCEO = 60 V, RthJA ≈ 200 K/W | Higher voltage headroom but significantly worse thermal performance; unsuitable for sustained 1 A operation | Choose only for low-duty-cycle pulse applications where PCB space prohibits SOT223 mounting |
Compared with BCP68-25 H6327, BCP56-16 offers tighter hFE tolerance at lower current but lacks thermal capability for full-load automotive use; ZTX851 trades package size for voltage margin and sacrifices thermal reliability in continuous conduction mode.

FAQ
Is BCP 68-25 H6327 pin-compatible with BCP69?
No - BCP68-25 (NPN) and BCP69 (PNP) share identical SOT223 package and pinout (Pin 1 = Base, Pin 2/4 = Collector/Emitter respectively), but polarity reversal means direct substitution requires circuit topology changes. Their complementary specification alignment (VCEO/VEBO, IC, hFE) enables matched push-pull design, not drop-in replacement.
What is the maximum allowable PCB copper area for thermal relief in SOT223 mounting?
Infineon recommends ≥ 100 mm² of 2 oz copper connected to the collector tab (Pins 2 & 4) for optimal RthJS performance. With this layout, junction-to-ambient resistance drops to ~45 K/W, allowing 1 A continuous operation at 85 °C ambient without forced air cooling.
Does BCP 68-25 H6327 support 100% duty cycle at 1 A?
Yes - at TA ≤ 60 °C with ≥ 100 mm² 2 oz copper thermal pad, the device sustains 1 A DC with VCE(sat) ≤ 0.5 V and TJ < 135 °C. Derating to 0.8 A is required above 85 °C ambient per the Ptot(TS) curve in the datasheet.
Can BCP 68-25 H6327 be used in linear regulator applications?
Yes - its 25 V VCES, 3 W Ptot, and stable hFE make it viable as a series pass element in medium-current linear regulators. However, VBE(ON) variation (0.6–1.0 V) requires precise reference and feedback design to maintain output accuracy across temperature and load.
