Product details

Overview

BC807W-Q from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT323 (SC-70) package, rated for −45 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 100–600 at V_CE = −1 V, I_C = −100 mA. It serves as a compact, AEC-Q101-qualified switching and amplification device in space-constrained automotive and industrial control circuits.

For engineers reviewing the BC807W-Q datasheet, BC807W-Q pinout, BC807W-Q application, or BC807W-Q equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT323 footprint details, and automotive-grade reliability context - all critical for low-voltage PNP switch selection in ECU power stages, LED drivers, and level-shifting interfaces.

Technical Context

This PNP BJT operates with base-emitter forward bias to control collector current flow, supporting linear amplification and saturated switching modes. Its −700 mV V_CE(sat) at I_C = −500 mA / I_B = −50 mA enables low-loss switching in 3.3 V/5 V rail applications.

Thermal performance is defined by R_th(j-a) = 625 K/W on standard FR4 PCB and 431 K/W with enhanced 1 cm² collector pad, enabling operation up to T_j = 150 °C. The device exhibits stable h_FE across −55 °C to +150 °C ambient, validated per AEC-Q101 stress testing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V: Maximum safe collector-emitter voltage under open-base condition; defines off-state blocking capability in 24 V automotive systems.
I_C	−500 mA continuous: Rated collector current at 25 °C; supports load switching up to ~200 mW dissipation in standard layout.
h_FE	100–600 at V_CE = −1 V, I_C = −100 mA: Wide DC current gain range ensures robust base drive design margin across production lots.
V_CE(sat)	−700 mV max at I_C = −500 mA, I_B = −50 mA: Low saturation voltage minimizes conduction loss in high-side switch configurations.
P_tot	290 mW with 1 cm² copper pad: Thermal limit determines maximum sustained power handling in PCB-mounted designs.
f_T	80 MHz: Transition frequency supports small-signal amplification up to audio band and fast digital switching (<50 ns rise/fall).
C_c	5 pF typical: Low collector capacitance reduces Miller effect, improving high-frequency stability in amplifier stages.

Pinout & Package

SOT323 (SC-70) plastic surface-mount package: 3-terminal, ultra-small outline (2.2 mm × 1.35 mm × 0.95 mm), optimized for high-density PCB layouts and reflow soldering.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; requires −50 mA base current to saturate at −500 mA collector load; polarity-sensitive for PNP turn-on.
2	Emitter (E)	Current source terminal; connected to higher potential rail (e.g., V_CC) in high-side switch topology.
3	Collector (C)	Current sink terminal; routes switched load current to ground or lower-potential node; thermally coupled to PCB pad.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive use including temperature cycling, HTRB, and ESD tests - enables direct deployment in engine control, body electronics, and ADAS modules.
Three h_FE variants	BC807W-Q (100–600), BC807-16W-Q (100–250), BC807-25W-Q (160–400): Enables precise base resistor selection without overdesign or gain instability.
Low V_BE	−1.2 V max at I_C = −500 mA: Reduces base drive power requirement and eases compatibility with 3.3 V logic-level microcontrollers.
High V_CB0	−50 V: Provides 5 V margin above V_CEO, enhancing robustness against inductive kickback in relay and solenoid drive applications.

Applications

Automotive Body Control Module

Industrial Sensor Interface

Use Scenario: Driving 12 V incandescent lamps and small relays in door lock, mirror, and interior lighting circuits.

IC Role / Device Role / Timing Role: High-side PNP switch controlling current path from battery rail to load; operates in saturated mode with <1 µs turn-off delay.

Use Value: −45 V rating withstands load-dump transients; AEC-Q101 qualification eliminates need for additional qualification effort.

Use Scenario: Level-shifting and buffering analog sensor outputs (e.g., NTC thermistors, potentiometers) into 3.3 V ADC inputs.

IC Role / Device Role / Timing Role: Emitter-follower amplifier providing low-output-impedance signal conditioning without inversion.

Use Value: Stable h_FE across −40 °C to +125 °C ensures consistent gain accuracy; low V_CE(sat) preserves dynamic range.

Consumer Power Management

Medical Diagnostic Equipment

Use Scenario: Enabling/disabling auxiliary power rails (e.g., USB charging ports, display backlights) in portable medical monitors.

IC Role / Device Role / Timing Role: Low-quiescent-current enable switch placed between main regulator and downstream LDOs or loads.

Use Value: −500 mA rating supports multi-load activation; SOT323 footprint saves board space in handheld enclosures.

Use Scenario: Isolating patient-connected analog front-end signals from digital processing sections using discrete optocoupler driver stages.

IC Role / Device Role / Timing Role: Fast-switching PNP driver for LED-based optocoupler input, ensuring <10 µs response in safety-critical isolation paths.

Use Value: 80 MHz f_T and low C_c support clean pulse transmission; −5 V V_EBO rating prevents emitter-base breakdown during ESD events.

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
BC807-16W-Q	h_FE = 100–250 (narrower range); identical V_CEO, I_C, package, and AEC-Q101 status	Better suited for fixed-gain designs where predictable base current is prioritized over wide gain tolerance	Select when designing for deterministic base resistor values and reduced h_FE variation impact on loop stability
MMBT3906LT1G	−40 V V_CEO, −200 mA I_C, h_FE = 100–300; SOT-23 package (larger than SOT323)	Limited to lower-power switching; not AEC-Q101 qualified; wider package pitch increases PCB area usage	Choose only for non-automotive, cost-sensitive consumer applications where −45 V/−500 mA rating is unnecessary

Compared with BC807-16W-Q, the BC807W-Q offers broader h_FE flexibility for variable-base-drive designs; versus MMBT3906LT1G, it delivers 2.5× higher current capability, 12% higher voltage rating, and automotive qualification - making it superior for next-generation compact, high-reliability control nodes.

FAQ

What is the maximum allowable junction temperature for BC807W-Q?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in Table 6 of the datasheet. Operation at this limit requires strict thermal management - including PCB copper area optimization and ambient temperature control - to avoid permanent degradation of h_FE and increased leakage currents.

Does BC807W-Q support pulsed operation beyond its DC current rating?

Yes: the peak collector current (I_CM) is rated at −1 A for single pulses ≤1 ms, provided duty cycle remains ≤2%. This enables short-duration surge handling in relay coil snubbing or capacitor charging circuits without thermal runaway.

How does the SOT323 package affect thermal performance compared to SOT-23?

The SOT323 (SC-70) package has smaller pad area and thinner mold compound than SOT-23, resulting in higher thermal resistance: R_th(j-a) = 625 K/W (standard layout) vs. ~400 K/W for typical SOT-23. To compensate, designers must use larger copper pours or thermal vias beneath the collector pad.

Is BC807W-Q pin-compatible with BC807-16W-Q or BC807-40W-Q?

Yes: all BC807W-Q series variants share identical SOT323 pinout (B-E-C), mechanical dimensions, and thermal footprint. Only h_FE range differs - allowing drop-in replacement when gain requirements align, without layout or schematic changes.
