Product details
Overview
BC807-40W H6327 from Infineon Technologies is a PNP silicon small-signal transistor optimized for general audio-frequency amplification and switching, featuring 45 V VCEO, 500 mA IC, hFE = 250–630 (at IC = 100 mA), VCE(sat) ≤ 0.7 V (IC = 500 mA, IB = 50 mA), and SOT-323 package. It serves in low-voltage bias networks, level shifters, and discrete logic interface stages.
For engineers reviewing the BC807-40W H6327 datasheet, BC807-40W H6327 pinout, BC807-40W H6327 application, or BC807-40W H6327 equivalent, this page delivers verified electrical specs, thermal derating curves, complementary NPN pairing (BC817-40W), and real-world use context for industrial control IO drivers and automotive body electronics.
Technical Context
This PNP bipolar junction transistor operates in linear amplification and saturated switching modes with guaranteed DC current gain across three hFE groups (16/25/40); BC807-40W belongs to the highest-gain group (hFE = 250–630 at IC = 100 mA, VCE = 1 V). Its low VCE(sat) and high fT (200 MHz typ.) support efficient operation in 24 V rail interfaces and medium-speed digital signal inversion.
Thermal performance is defined by RthJS ≤ 80 K/W (SOT-323, TS ≤ 130 °C), enabling stable operation up to 150 °C junction temperature. Complementary NPN types BC817-40W/BC818-40W share identical gain grading and package footprint for push-pull stage design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - supports operation in 36 V automotive and industrial supply rails without breakdown |
| IC | 500 mA continuous - drives LED arrays, relay coils, or logic-level MOSFET gates directly |
| hFE | 250–630 @ IC = 100 mA - enables low-base-drive designs for high-efficiency switching |
| VCE(sat) | ≤ 0.7 V @ IC = 500 mA, IB = 50 mA - minimizes conduction loss in power-switching nodes |
| fT | 200 MHz typical - sufficient for audio-band amplification and <10 MHz digital signal buffering |
| RthJS | ≤ 80 K/W - allows 250 mW dissipation at TS ≤ 130 °C in compact SOT-323 layout |
| VEB0 | 5 V - sets maximum reverse-bias limit for base-emitter junction in active bias networks |
Pinout & Package
BC807-40W H6327 uses the SOT-323 (SC-70) plastic surface-mount package: 1.9 mm × 1.3 mm × 0.95 mm, lead-free (RoHS compliant), rated per AEC-Q101 for automotive reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current sink node; connects to higher potential rail in PNP switch configuration |
| 2 (Base) | B | Control input; requires ~50 mA drive for full saturation at 500 mA collector load |
| 3 (Collector) | C | Output node; ties to load and ground return path in common-emitter topology |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive body electronics, including door modules and lighting control units |
| High hFE group (40) | Reduces required base drive current by >2× vs. BC807-16W, lowering MCU GPIO loading |
| Low VCE(sat) | Enables <0.35 W conduction loss at 500 mA, critical for thermally constrained PCBs |
| Complementary NPN pairing | BC817-40W shares identical hFE binning and SOT-323 footprint for matched push-pull output stages |
Applications
| Automotive Door Module Driver | Industrial PLC Input Buffer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP small-signal transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC807-40 E6327 | SOT-23 package (larger footprint, higher RthJA), same hFE bin and electrical specs | Less suitable for ultra-dense layouts; preferred where manual rework or thermal margin >215 K/W is acceptable | Select when board space permits larger package and thermal management uses copper pour rather than solder-point cooling |
| MMBT4403LT1G | Lower hFE (100–300), higher VCE(sat) (≤ 0.75 V), same SOT-323 footprint and VCEO | Marginally adequate for 500 mA loads only with increased base drive; less robust at elevated temperature | Choose only if cost sensitivity outweighs gain stability and thermal headroom requirements |
Compared with BC807-40W H6327, BC807-40 E6327 trades thermal efficiency for mechanical robustness and ease of handling, while MMBT4403LT1G sacrifices gain consistency and saturation voltage for broader distributor availability-neither offers superior performance in AEC-Q101-critical or high-current-density designs.

FAQ
Is BC807-40W H6327 RoHS compliant and halogen-free?
Yes. BC807-40W H6327 is fully RoHS compliant (2011/65/EU) and halogen-free per IEC 61249-2-21. The SOT-323 package uses lead-free matte tin plating on terminals, and material declarations confirm bromine and chlorine content below 900 ppm each.
What is the maximum allowable base current for continuous operation?
The absolute maximum rated base current is 100 mA (DC), but for reliable long-term operation at IC = 500 mA, the recommended continuous base current is ≤ 50 mA. Exceeding this risks localized heating at the base-emitter junction and accelerated hFE degradation above 125 °C junction temperature.
Can BC807-40W H6327 replace BC807-25W in an existing design?
Yes, with verification of gain-dependent timing margins. BC807-40W has higher hFE (250–630 vs. 160–400), which may reduce base drive requirements and improve saturation depth-but could slightly increase turn-off delay due to minority carrier storage. Layout and drive network should be validated for worst-case VCC and temperature.
Does Infineon provide SPICE models for BC807-40W H6327?
Yes. Infineon publishes a validated Gummel-Poon SPICE model for BC807-40W (including temperature-dependent parameters and parasitic capacitances) on its official product page under "Design Support → Simulation Models". The model covers DC, AC, and transient behavior from –40 °C to 150 °C.
