Product details
Overview
BC808-25W H6327 from Infineon Technologies is a PNP silicon general-purpose audio-frequency transistor in SOT323 package, rated for 25 V VCEO, 500 mA IC, and 250 mW Ptot at TS ≤ 130 °C, with hFE = 160–250 (IC = 100 mA, VCE = 1 V), used in low-voltage switching and linear amplification stages of consumer audio and power management circuits.
For engineers reviewing the BC808-25W H6327 datasheet, BC808-25W H6327 pinout, BC808-25W H6327 application, or BC808-25W H6327 equivalent, key selection criteria include verified VCEO/VCBO ratings, hFE group consistency across temperature, saturation voltage under 500 mA drive, thermal resistance RthJS ≤ 80 K/W, and RoHS-compliant SOT323 footprint compatibility.
Technical Context
This PNP bipolar junction transistor operates in active, saturation, and cutoff regions for analog amplification and digital switching. Its design supports stable DC current gain over -40 °C to 105 °C and maintains VCE(sat) ≤ 0.7 V at IC = 500 mA / IB = 50 mA.
It features complementary pairing with NPN BC817-25W/BC818-25W, shares identical SOT323 mechanical outline and pinout (Emitter–Base–Collector), and meets AEC-Q101 qualification for automotive-grade reliability in non-safety-critical subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 25 V - Maximum collector-emitter voltage before breakdown under open-base condition |
| IC | 500 mA - Continuous collector current rating defining safe linear/saturation operation |
| hFE | 160–250 - DC current gain range at 100 mA IC, 1 V VCE, enabling predictable base drive sizing |
| VCE(sat) | ≤ 0.7 V - Low saturation voltage at 500 mA IC/50 mA IB, minimizing conduction loss in switch mode |
| RthJS | ≤ 80 K/W - Junction-to-soldering-point thermal resistance for SOT323 package, critical for thermal derating |
| fT | 200 MHz - Transition frequency indicating usable bandwidth for AF and low-speed switching |
| Ccb | 8 pF - Collector-base capacitance at 10 V VCB, influencing high-frequency gain roll-off |
Pinout & Package
Package: SOT323 - Surface-mount plastic package with gull-wing leads, 1.3 mm × 2.1 mm footprint, 0.95 mm height, suitable for automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current sink terminal; connected to higher potential in PNP configuration; defines reference for base-emitter bias |
| 2 (Base) | B | Control input; negative-going signal turns device ON; requires current-limited drive per hFE and IC |
| 3 (Collector) | C | Current source terminal; supplies load current when saturated; tied to lower-potential rail in common-emitter switch |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including body control modules and lighting drivers requiring extended temperature and life-cycle reliability |
| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles up to 260 °C peak |
| Low VCE(sat) | ≤ 0.7 V at full-rated 500 mA enables efficient switching in battery-powered and thermally constrained designs |
| High hFE group (25) | Narrower gain spread (160–250) improves predictability in current mirror and amplifier bias networks |
| Complementary NPN pairing | Direct match with BC817-25W/BC818-25W simplifies push-pull stage design and BOM consolidation |
Applications
| Audio Amplifier Stage | Load Switch Driver |
|---|---|
Use Scenario: Small-signal preamplification in portable speaker systems and headphone outputs. IC Role / Device Role / Timing Role: PNP emitter-follower configured for impedance matching and current boosting. Use Value: Low VCE(sat) and stable hFE ensure minimal distortion and consistent gain across battery discharge cycles. | Use Scenario: High-side switch controlling 12 V LED arrays in automotive interior lighting. IC Role / Device Role / Timing Role: Saturated PNP switch driven by microcontroller GPIO through current-limiting resistor. Use Value: 500 mA IC rating and ≤ 0.7 V VCE(sat) limit power dissipation to < 350 mW at full load. |
| Level Translation Circuit | Current Mirror Reference |
Use Scenario: Bidirectional logic-level translation between 3.3 V MCU and 5 V sensor interface. IC Role / Device Role / Timing Role: PNP-based level shifter operating in active region for fast edge response. Use Value: fT = 200 MHz ensures sub-5 ns propagation delay with proper base termination. | Use Scenario: Precision current mirroring in analog front-end biasing networks. IC Role / Device Role / Timing Role: Matched PNP pair (with BC807-25W) establishing stable reference current. Use Value: Tight hFE grouping (160–250) reduces mirror ratio error to < ±8% over temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC808-25 LT1G (ON Semiconductor) | Same VCEO/IC/hFE specs; SOT-23 package (larger footprint than SOT323) | Requires PCB layout change; higher RthJA due to larger thermal mass | Select if SOT-23 is already standardized in design and board space allows |
| MMBT808 (Nexperia) | Identical SOT323 footprint; VCEO = 25 V, but hFE min = 100 (wider spread: 100–300) | Less predictable base drive; may require recalculating bias resistors | Choose for cost-sensitive industrial controls where gain tolerance is relaxed |
Compared with BC808-25W H6327, BC808-25 LT1G trades compactness for thermal margin via SOT-23, while MMBT808 sacrifices hFE consistency for broader availability-making the Infineon part optimal where SOT323 size and tight gain control are jointly required.

FAQ
What is the maximum allowable junction temperature for BC808-25W H6327?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent degradation of hFE and increased leakage. Derating is required above TS = 130 °C, where total power dissipation drops linearly to zero at 150 °C.
Is BC808-25W H6327 pin-compatible with BC807-25W?
Yes - both share identical SOT323 package and pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. They differ only in VCEO (45 V vs. 25 V) and VCBO (50 V vs. 30 V), making BC807-25W suitable for higher-voltage PNP roles while maintaining mechanical and layout compatibility.
Does BC808-25W H6327 support pulse operation beyond its DC ratings?
Yes - the datasheet provides permissible pulse load curves showing Ptot(max)/Ptot(DC) ratios up to 10× for pulse widths < 100 µs (duty cycle ≤ 0.005). This enables short-duration surge handling in motor drive or LED strobe applications without exceeding thermal limits.
How does the hFE group "25" affect circuit design?
The "25" designation indicates a factory-binned hFE range of 160–250 at IC = 100 mA and VCE = 1 V. Designers must size base resistors using hFE(min) = 160 to guarantee saturation under worst-case conditions, while recognizing that higher gain may reduce base drive power in linear stages.
