Product details

Overview

BC807-40 E6327 from Infineon Technologies is a PNP silicon general-purpose audio-frequency transistor with V_CEO = 45 V, I_C = 500 mA, h_FE = 250–630 (at I_C = 100 mA), V_CE(sat) ≤ 0.7 V (I_C = 500 mA, I_B = 50 mA), and SOT-23 package. It serves as a medium-power switching or linear amplification device in low-voltage DC control circuits, LED drivers, and signal-level interface stages.

For engineers reviewing the BC807-40 E6327 datasheet, BC807-40 E6327 pinout, BC807-40 E6327 application, or BC807-40 E6327 equivalent, key selection criteria include guaranteed high-current gain group (h_FE ≥ 250), low saturation voltage for efficient switching, AEC-Q101 qualification for automotive-grade reliability, and RoHS-compliant SOT-23 packaging compatible with high-density PCB assembly.

Technical Context

This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with defined DC current gain (h_FE) across collector currents from 10 mA to 500 mA and junction temperatures from –40 °C to +150 °C. Its f_T = 200 MHz enables stable operation up to mid-frequency signal conditioning tasks.

The device features complementary NPN counterparts (BC817–BC818 series), supports pulsed operation with duty-cycle-dependent thermal derating, and maintains specified V_(BR)CEO, V_(BR)CBO, and leakage (I_CBO ≤ 0.1 µA at 25 °C) under rated bias conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum safe collector-emitter voltage before breakdown in open-base configuration
I_C	500 mA - Continuous DC collector current rating defining usable load drive capability
h_FE (I_C = 100 mA)	250–630 - Guaranteed DC current gain range enabling predictable base drive sizing
V_CE(sat)	≤ 0.7 V - Low saturation voltage minimizes power loss and heating during switching
f_T	200 MHz - Transition frequency confirming suitability for audio and low-speed digital signal amplification
P_tot (T_S ≤ 79 °C)	330 mW - Total power dissipation limit at solder-point temperature, defining thermal design margin
R_thJS	≤ 215 K/W - Junction-to-solder-point thermal resistance guiding heatsinking requirements

Pinout & Package

BC807-40 E6327 is housed in a standard SOT-23 plastic surface-mount package with gull-wing leads, optimized for automated placement and reflow soldering on compact PCBs.

Pin/Terminal	Circuit Role	Design Meaning

2 (Base)	B	Control input requiring ~1.2 V forward bias (V_BE(sat)) to drive 500 mA collector current
3 (Collector)	C	Current sink terminal; connected to load and supply return path in common-emitter topology

Key Features

Feature	Design Value

Low V_CE(sat) at high I_C	Enables >90% efficiency in 5–12 V DC switching applications with minimal thermal rise
Pb-free / RoHS compliant	Meets global environmental compliance requirements without compromising solderability or reliability
Complementary NPN pairing	Direct interoperability with BC817-40/BC818-40 for push-pull output stages and H-bridge drivers

Applications

IC Role / Device Role / Timing Role: PNP current sink amplifier providing inverted logic-level control with low dropout.

Use Value: V_CE(sat) ≤ 0.7 V ensures <100 mW dissipation at full LED current, eliminating need for heatsinking.

Use Scenario: Controlling 12 V solenoid lock coils (≈300 mA peak) in vehicle door modules.

IC Role / Device Role / Timing Role: Medium-power DC switch interfacing MCU outputs to inductive loads with flyback protection.

Use Value: AEC-Q101 qualification and 150 °C T_j rating support continuous operation in under-dash environments.

DC Motor Speed Control

Industrial Sensor Signal Conditioning

Use Scenario: PWM-driven 3–6 V brushed DC motor (max 400 mA) in portable equipment.

IC Role / Device Role / Timing Role: High-gain PNP switch operating in saturation/cutoff to modulate average motor current.

Use Value: h_FE ≥ 250 allows direct drive from 3.3 V logic with ≤10 kΩ base resistor, simplifying gate driver design.

Use Scenario: Amplifying low-level analog signals (e.g., thermistor or bridge sensor outputs) into 0–5 V ranges.

IC Role / Device Role / Timing Role: Linear-mode emitter-follower buffer isolating sensitive sensors from downstream ADC inputs.

Use Value: Stable h_FE vs. temperature (–40 to +125 °C) ensures consistent gain accuracy over industrial ambient ranges.

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; SOT-23 package but non-AEC-Q101 qualified and not RoHS-compliant (Pb-containing)	Restricted to non-automotive commercial applications where lead-free and automotive qualification are not required	Select only if cost sensitivity outweighs compliance and reliability requirements
MMBT3906LT1G	Lower h_FE (min 100 vs. 250), same V_CEO/I_C, slightly higher V_CE(sat) (≤ 0.4 V @ 10 mA but ≤ 0.65 V @ 50 mA)	Less suitable for high-current linear amplification; better for low-power switching where gain consistency is secondary	Choose when lower base drive current suffices and AEC-Q101 is unnecessary

Compared with BC807-40TA and MMBT3906LT1G, BC807-40 E6327 delivers superior gain stability, automotive-grade reliability, and RoHS compliance-making it optimal for safety-critical or high-volume industrial designs where long-term supply continuity and regulatory alignment matter.

FAQ

Is BC807-40 E6327 pin-compatible with BC807-16 or BC807-25?

Yes-BC807-40 E6327 shares identical SOT-23 pinout (E-B-C) and mechanical footprint with all BC807 variants. The suffix "40" denotes h_FE group only; electrical differences are limited to guaranteed minimum current gain (250 vs. 100 or 160), with no impact on physical layout or PCB design.

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current (I_B) is 100 mA per datasheet. For reliable long-term operation at I_C = 500 mA, recommended I_B is 50 mA (h_FE = 10), ensuring deep saturation while staying within thermal limits and avoiding base-emitter junction degradation.

Does BC807-40 E6327 support pulsed operation beyond its DC ratings?

Yes-pulse operation up to I_CM = 1000 mA is permitted with duty cycle ≤ 2% and pulse width < 300 µs. Thermal performance must be verified using R_thJS ≤ 215 K/W and the provided P_tot(max)/P_tot(DC) vs. t_p curves to avoid junction overheating.

Can BC807-40 E6327 replace BC808-40 in existing designs?

No-BC808-40 has V_CEO = 25 V and V_CBO = 30 V, whereas BC807-40 specifies 45 V and 50 V respectively. Substituting BC807-40 into a BC808-40 design is electrically safe, but the reverse risks breakdown in 30–45 V applications; always verify voltage stress margins before interchange.
