Product details

Overview

BC807-40QBH-Q from Nexperia is a PNP general-purpose transistor in a DFN1110D-3 (SOT8015) leadless SMD package, rated for −45 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 250–600 at V_CE = −1 V and I_C = −100 mA. It operates up to 175 °C junction temperature and is AEC-Q101 qualified for automotive use.

For engineers reviewing the BC807-40QBH-Q datasheet, BC807-40QBH-Q pinout, BC807-40QBH-Q application, or BC807-40QBH-Q equivalent, this device supports space-constrained switching and amplification where high-temperature reliability, AOI-compatible side-wettable flanks, and low-profile packaging (1.1 × 1.0 × 0.5 mm) are critical.

Technical Context

This PNP bipolar junction transistor delivers stable current amplification across −55 °C to +175 °C ambient range, with thermal resistance R_th(j-a) as low as 272 K/W on 70 μm FR4 PCB - enabling robust performance in thermally demanding automotive ECUs and industrial controllers.

Its DFN1110D-3 package features side-wettable flanks for automated optical inspection of solder joints, and its pulsed h_FE test condition (t_p ≤ 300 μs, δ ≤ 0.02) ensures accurate small-signal gain characterization under transient operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V: Maximum collector-emitter voltage before breakdown; defines safe operating voltage headroom in PNP switch configurations.
I_C	−500 mA continuous: Rated collector current at 25 °C ambient; supports medium-power load switching without forced cooling.
h_FE	250–600 at V_CE = −1 V, I_C = −100 mA: High and tightly binned DC current gain enables precise base drive sizing in linear and saturated switching modes.
P_tot	550 mW on 70 μm FR4 PCB: Total power dissipation limit defining thermal design margin for surface-mount layout.
T_j	175 °C maximum junction temperature: Enables operation in under-hood automotive environments and sealed industrial enclosures.
V_CE(sat)	−700 mV max at I_C = −500 mA, I_B = −50 mA: Low saturation voltage minimizes conduction loss and heat generation in high-current switching.
f_T	80 MHz: Transition frequency supporting audio-frequency amplification and fast digital switching up to ~10 MHz.

Pinout & Package

DFN1110D-3 (SOT8015) is an ultra-thin, leadless plastic package measuring 1.1 mm × 1.0 mm × 0.5 mm, with side-wettable flanks for AOI-compatible reflow soldering and enhanced thermal conduction via exposed copper pad.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on.
2	Emitter (E)	Current source terminal in PNP configuration; typically connected to higher potential rail in high-side switch applications.
3	Collector (C)	Current sink terminal; connects to load and ground or lower-potential node in standard switching topologies.

Key Features

Feature	Design Value
Side-wettable flanks	Enables 100% automated optical inspection (AOI) of solder joints without X-ray, reducing post-reflow defect escapes in automotive production.
AEC-Q101 qualification	Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD testing - suitable for engine control, body electronics, and ADAS modules.
175 °C junction rating	Supports operation in high-ambient environments such as powertrain compartments and industrial motor drives without derating or heatsinking.
Low 0.5 mm profile	Reduces board stack height and improves mechanical robustness in ultra-thin portable and wearable electronics designs.
Three h_FE bins	BC807-40QBH-Q's 250–600 gain range allows predictable biasing in analog amplifiers and consistent saturation in digital switches across manufacturing lots.

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
BC807-40,115 (SOT23)	Same electrical specs but in larger SOT23 package (2.9 × 1.3 × 1.0 mm); no side-wettable flanks; R_th(j-a) ≈ 400 K/W.	Lacks AOI support and thermal performance; unsuitable for high-density automotive PCBs requiring inspection traceability.	Select when legacy SOT23 footprint compatibility or hand-soldering is required; avoid for new AEC-Q101 designs.
MMBT3906LT1G	−40 V V_CEO, −200 mA I_C, h_FE 100–300; SOT23 package; not AEC-Q101 qualified.	Lower voltage/current ratings and no automotive qualification limit use to non-safety-critical consumer applications.	Choose only for cost-sensitive, non-automotive, low-power signal switching where AEC-Q101 and −45 V rating are unnecessary.

Compared with BC807-40,115 and MMBT3906LT1G, BC807-40QBH-Q uniquely combines AEC-Q101 qualification, side-wettable flanks for AOI, and superior thermal performance in a 1.1 mm × 1.0 mm footprint - making it the only option for next-generation automotive and high-reliability industrial switching where space, inspection, and temperature constraints converge.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA per datasheet limiting values, but continuous operation must stay within thermal limits. At I_C = −500 mA and h_FE ≥ 250, recommended I_B is −2 mA minimum for saturation; typical design uses −5 to −50 mA depending on switching speed and V_CE(sat) target. Derate above 25 °C ambient using thermal resistance curves.

Can BC807-40QBH-Q replace BC807-40 in existing SOT23 designs?

No - BC807-40QBH-Q uses DFN1110D-3 (SOT8015), which is physically incompatible with SOT23 footprints. The pinout (B-E-C) matches, but dimensions (1.1 × 1.0 mm vs. 2.9 × 1.3 mm), solder land pattern, and thermal pad requirements differ. A PCB redesign is mandatory for migration.

Is the marking code 'F8' laser-etched or ink-printed?

The marking code 'F8' for BC807-40QBH-Q is laser-etched onto the top surface of the DFN1110D-3 package, ensuring permanent legibility after reflow and conformal coating - a requirement for automotive traceability and long-term identification in harsh environments.

Does this transistor support pulsed operation beyond its DC ratings?

Yes - the datasheet specifies I_CM = −1 A for single pulses ≤ 1 ms, and h_FE is characterized under pulsed conditions (t_p ≤ 300 μs, δ ≤ 0.02). This enables short-duration surge handling in motor startup or fault protection circuits, provided average power remains within P_tot limits and thermal mass prevents junction overheating.
