Product details

Overview

BC807-25B5000 from Nexperia is a PNP silicon general-purpose audio-frequency transistor with h_FE = 160–400 at I_C = 100 mA, V_CE = 1 V; V_CEO = 45 V; I_C = 500 mA continuous; V_CE(sat) ≤ 0.7 V at I_C = 500 mA / I_B = 50 mA; packaged in SOT23. It serves as a low-voltage switching and linear amplification device in power management and signal conditioning stages of industrial control modules.

For engineers reviewing the BC807-25B5000 datasheet, BC807-25B5000 pinout, BC807-25B5000 application, or BC807-25B5000 equivalent, key selection criteria include guaranteed h_FE group 25 performance across temperature, low saturation voltage for efficient switching, AEC-Q101 qualification for automotive-grade reliability, and SOT23 footprint compatibility with high-density PCB layouts.

Technical Context

This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with DC current gain specified across I_C = 10 mA to 500 mA and V_CE = 1 V. Its thermal resistance R_thJS ≤ 215 K/W (SOT23) enables stable operation up to T_j = 150 °C under defined board conditions.

AC characteristics include f_T = 200 MHz at I_C = 50 mA, V_CE = 5 V, supporting moderate-speed switching and AF amplification. C_cb = 8 pF and C_eb = 60 pF at rated bias points define its small-signal capacitance profile for stability analysis.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum collector-emitter blocking voltage before breakdown in open-base configuration
I_C (cont.)	500 mA - Continuous collector current rating defining safe DC load drive capability
h_FE (grp. 25)	160–400 - Guaranteed DC current gain range at I_C = 100 mA, V_CE = 1 V for predictable base drive sizing
V_CE(sat)	≤ 0.7 V - Low saturation voltage ensures minimal conduction loss in switching applications
f_T	200 MHz - Transition frequency enabling use in audio-band amplifiers and <10 MHz digital switches
R_thJS	≤ 215 K/W - Junction-to-solder-point thermal resistance determining heatsinking requirements on standard FR4
P_tot	330 mW - Total power dissipation limit at T_S ≤ 79 °C, constraining thermal design margin

Pinout & Package

BC807-25B5000 is housed in a plastic SOT23 surface-mount package with gull-wing leads, optimized for automated placement and reflow soldering. The package measures 2.9 × 1.3 × 1.0 mm and supports JEDEC-compliant board layout standards.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal accepting forward-biased current to enable conduction between emitter and collector
2	Emitter (E)	Current source terminal; connected to higher potential in PNP operation; defines reference for V_BE bias
3	Collector (C)	Current sink terminal; output node where load is typically connected to ground or lower potential rail

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive electronics per stress test requirements including HTOL, TC, HAST, and ESD
RoHS-compliant (Pb-free)	Meets EU Directive 2011/65/EU; no lead in solderable terminations or die attach
High h_FE group consistency	Guaranteed 160–400 spread ensures predictable base resistor selection without binning
Low V_CE(sat)	≤ 0.7 V at rated I_C/I_B reduces power loss and self-heating in saturated switch mode
Complementary NPN pairing	Direct counterpart to BC817-25 series for push-pull, differential, and bridge configurations

Applications

Use Scenario: Driving small DC brush motors (≤12 V, ≤300 mA) in HVAC actuators and seat positioners.

IC Role / Device Role / Timing Role: PNP switch controlling motor supply path via emitter-follower configuration with logic-level base drive.

Use Value: V_CE(sat) ≤ 0.7 V minimizes voltage drop and heat generation during continuous 300 mA operation.

Use Scenario: Enabling/disabling +5 V or +3.3 V rails in multi-rail embedded systems using microcontroller GPIO.

IC Role / Device Role / Timing Role: High-side switch providing controlled power-up sequencing and fault-isolation capability.

Use Value: h_FE ≥ 160 allows full saturation with ≤5 mA base current, reducing MCU I/O loading.

LED Current Regulator

Use Value: C_cb = 8 pF and C_eb = 60 pF support clean edge integrity without added gate-drive complexity.

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
BC807-25,115 (Nexperia)	Same die, identical h_FE group and electrical specs; differs only in tape-and-reel packaging (3000 pcs vs. 5000 pcs).	No functional difference; suitable for identical circuit roles and layout.	Select based on volume requirement and assembly line feeder compatibility.
MMBT807 (ON Semiconductor)	Same SOT23 package and pinout; h_FE min = 100 (vs. 160), V_CEO = 45 V, V_CE(sat) max = 0.75 V at same test conditions.	Acceptable where lower h_FE margin is tolerable; may require larger base resistor or tighter thermal control.	Use when cross-manufacturer sourcing is required and gain tolerance can be relaxed by design validation.

Compared with BC807-25B5000, BC807-25,115 offers identical performance in a different reel size, while MMBT807 trades guaranteed h_FE headroom for broader second-source availability-critical for long-lifecycle industrial designs requiring dual-supplier strategy.

FAQ

Is BC807-25B5000 suitable for automotive applications?

Yes. BC807-25B5000 is qualified to AEC-Q101 standards, including high-temperature operating life, temperature cycling, and ESD testing. Its guaranteed h_FE group, V_CEO = 45 V, and operation up to T_j = 150 °C make it appropriate for body electronics, lighting controls, and sensor interface circuits in passenger vehicles.

What is the maximum allowable base current for continuous operation?

The absolute maximum rated base current (I_B) is 100 mA, but for reliable long-term operation, the recommended continuous base current is ≤50 mA-aligned with the V_CE(sat) test condition. Exceeding this risks localized heating and gain degradation, especially above 85 °C ambient.

Can BC807-25B5000 replace BC807-16 or BC807-40 in existing designs?

Yes, with verification. All three share identical package, pinout, and voltage/current ratings. The primary difference is h_FE group: BC807-16 (100–250), BC807-25 (160–400), BC807-40 (250–630). Substitution requires checking whether base drive and thermal margins remain sufficient under worst-case gain extremes.

Does BC807-25B5000 have a built-in ESD protection diode?

No. BC807-25B5000 is a bare-die bipolar transistor without integrated ESD protection. External protection (e.g., series resistor + TVS on base line) is recommended in environments with >2 kV HBM exposure risk, particularly in handling or connector-facing circuits.
