Product details
Overview
BC807-40 E6433 from Nexperia is a PNP silicon general-purpose audio-frequency transistor with VCEO = 45 V, IC = 500 mA, hFE = 250–630 (at IC = 100 mA), VCE(sat) ≤ 0.7 V (at IC = 500 mA), and SOT23 package. It serves as a medium-power switching or linear amplification device in low-voltage DC control circuits, LED drivers, and relay interface stages.
For engineers reviewing the BC807-40 E6433 datasheet, BC807-40 E6433 pinout, BC807-40 E6433 application, or BC807-40 E6433 equivalent, key selection criteria include guaranteed hFE group 40 performance across temperature, low saturation voltage under high current, RoHS-compliant SOT23 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with defined DC gain grouping (hFE = 250–630 at IC = 100 mA, VCE = 1 V) and maintains stable fT ≈ 200 MHz for moderate-frequency signal handling. Its complementary NPN counterpart is BC817-40.
Thermal design relies on RthJS ≤ 215 K/W (SOT23) and derated power dissipation down to 0 mW at TS = 150 °C. Cutoff currents (ICBO ≤ 0.1 µA at 25 °C; ≤50 µA at 150 °C) ensure leakage integrity in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown in open-base configuration |
| IC | 500 mA - Continuous DC collector current rating defining switching/linear load capacity |
| hFE (grp. 40) | 250–630 - Guaranteed DC current gain range at IC = 100 mA, enabling predictable base drive sizing |
| VCE(sat) | ≤ 0.7 V - Low saturation voltage at IC = 500 mA / IB = 50 mA, minimizing conduction loss |
| fT | 200 MHz - Transition frequency confirming usable bandwidth up to ~10–50 MHz in small-signal amplifiers |
| RthJS | ≤ 215 K/W - Junction-to-solder-point thermal resistance for SOT23 package, critical for thermal margin calculation |
| Ptot | 330 mW - Total power dissipation limit at TS ≤ 79 °C, constraining continuous operation in ambient-limited PCBs |
Pinout & Package
SOT23 plastic surface-mount package with standard 3-pin configuration and JEDEC TO-236AB outline; moisture sensitivity level (MSL) 1, Pb-free (RoHS compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires series resistor to limit IB and prevent thermal runaway |
| 2 | Emitter (E) | Common terminal for PNP operation; connected to higher potential rail in typical switch configurations |
| 3 | Collector (C) | Output terminal sourcing current to load; polarity reversed vs. NPN devices in circuit layout |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB), supporting under-hood and infotainment use |
| hFE group 40 | Narrower gain spread (250–630) than group 16/25, reducing base bias variability in production designs |
| VCE(sat) ≤ 0.7 V | Enables <100 mW conduction loss at 500 mA, suitable for thermally constrained LED or solenoid drivers |
| Complementary pairing | Direct functional match with BC817-40 (NPN), simplifying push-pull stage design without gain mismatch |
| RoHS-compliant SOT23 | Standardized footprint compatible with automated pick-and-place and reflow processes; no lead exemption required |
Applications
| LED Driver Stage | Relay Interface Circuit |
|---|---|
Use Scenario: Driving high-brightness white LEDs from 5 V or 12 V rails in automotive interior lighting. IC Role / Device Role / Timing Role: PNP switch controlling LED anode current path; emitter tied to supply, collector to LED cathode via current-limiting resistor. Use Value: VCE(sat) ≤ 0.7 V ensures >90% efficiency at 350 mA, while hFE ≥ 250 allows microcontroller GPIO direct drive with minimal base resistor. | Use Scenario: Isolating and amplifying logic-level signals to energize 12 V automotive relays. IC Role / Device Role / Timing Role: Medium-current PNP buffer stage between MCU output and relay coil, providing current gain and voltage level shift. Use Value: 500 mA IC rating supports common 12 V/160 Ω coils (75 mA), with headroom for inrush; AEC-Q101 ensures reliability over 10-year vehicle life. |
| Low-Voltage DC Motor Control | Power Supply Enable Switch |
Use Scenario: PWM-driven bidirectional motor control using discrete H-bridge with PNP high-side switches. IC Role / Device Role / Timing Role: High-side PNP switch in half-bridge topology; base driven by level-shifted PWM signal. Use Value: Fast fT ≈ 200 MHz enables clean 20 kHz PWM edge response; low VCE(sat) reduces heat generation during 100% duty cycle operation. | Use Scenario: Enabling/disabling auxiliary 3.3 V or 5 V LDO outputs in multi-rail embedded power systems. IC Role / Device Role / Timing Role: Low-leakage PNP pass element controlled by system supervisor IC or microcontroller. Use Value: ICBO ≤ 0.1 µA at 25 °C prevents standby current degradation; SOT23 footprint minimizes board area in space-constrained PMIC layouts. |
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 |
|---|---|---|---|
| BC807-40TA | Same electrical specs; SOT23-3 package, tape-and-reel packaging variant (E6433 = bulk) | No functional difference; identical placement and soldering profile | Select for automated assembly requiring reel-fed feeders |
| MMBT4403 | Lower hFE (100–300), higher VCE(sat) (≤ 0.75 V), same SOT23 footprint | Marginally reduced current gain and higher conduction loss limit use in high-efficiency or precision bias designs | Acceptable where gain tolerance >30% and thermal budget allows +50 mW loss |
Compared with BC807-40 E6433, BC807-40TA offers identical performance in tape-and-reel form for SMT lines, while MMBT4403 trades gain and saturation voltage for broader legacy availability-making it viable only when hFE ≥ 250 and VCE(sat) ≤ 0.7 V are not design-critical.

FAQ
Is BC807-40 E6433 pin-compatible with BC807-25 or BC807-16?
Yes-BC807-40 E6433 shares identical SOT23 pinout (B-E-C) and mechanical dimensions with BC807-16 and BC807-25. Only the hFE group differs (16/25/40), so substitution is electrically valid if gain requirements permit. No PCB layout change is needed.
What is the maximum operating temperature for continuous use?
The junction temperature (Tj) must not exceed 150 °C. With RthJS ≤ 215 K/W and Ptot = 330 mW at TS ≤ 79 °C, sustained operation requires board-level thermal management-such as copper pour under the pad-to maintain solder-point temperature below 79 °C.
Does BC807-40 E6433 support pulsed operation beyond its DC ratings?
Yes-pulse testing (t < 300 µs, duty cycle < 2%) permits peak collector current up to 1000 mA and peak base current up to 200 mA. Derating curves in the datasheet define allowable Ptot(max)/Ptot(DC) ratios versus pulse width for safe transient operation.
Can BC807-40 E6433 replace BC808-40 in existing designs?
No-BC808-40 has VCEO = 25 V and VCBO = 30 V, while BC807-40 specifies 45 V and 50 V respectively. Substituting BC807-40 into a BC808-40 design is safe electrically, but the reverse risks breakdown in 30–45 V circuits; always verify voltage margins before interchange.
