Product details

Overview

BC807-40QB-Q from Nexperia is a PNP general-purpose bipolar junction transistor in a DFN1110D-3 (SOT8015) leadless 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 serves as a compact, AEC-Q101-qualified switching or amplification device in space-constrained automotive and industrial control circuits.

For engineers reviewing the BC807-40QB-Q datasheet, BC807-40QB-Q pinout, BC807-40QB-Q application, or BC807-40QB-Q equivalent, this page delivers verified electrical specs, thermal derating behavior, side-wettable flank soldering guidance, and validated automotive-grade alternatives - all aligned to Nexperia's Rev. 2 (May 2021) product data sheet.

Technical Context

This PNP BJT operates with a maximum collector-emitter breakdown voltage of −45 V and supports pulsed peak currents up to −1 A. Its h_FE range (250–600) enables stable biasing across temperature (−55 °C to 150 °C) and load conditions, while low V_CEsat (≤ −700 mV at I_C = −500 mA, I_B = −50 mA) ensures efficient saturation in low-voltage switching.

The DFN1110D-3 package features side-wettable flanks for automated optical inspection (AOI) of solder joints, 0.65 mm pitch, and 1.1 × 1.0 × 0.48 mm body dimensions. Thermal resistance R_th(j-a) is 272 K/W on 70 μm FR4 copper, supporting power dissipation up to 460 mW at T_amb ≤ 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V: Maximum safe collector-emitter voltage before breakdown under open-base condition.
I_C	−500 mA continuous: Sustained collector current capability at 25 °C ambient without derating.
h_FE	250–600 at V_CE = −1 V, I_C = −100 mA: Ensures reliable DC bias stability in linear and switching modes.
V_CEsat	≤ −700 mV at I_C = −500 mA, I_B = −50 mA: Minimizes conduction loss and self-heating during saturation.
P_tot	460 mW on 70 μm FR4 PCB: Maximum steady-state power dissipation before thermal throttling.
T_j max	150 °C: Absolute maximum junction temperature, defining upper thermal operating limit.
R_th(j-a)	272 K/W (70 μm FR4): Quantifies thermal path efficiency from die to ambient air.

Pinout & Package

DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin plastic package (1.1 × 1.0 × 0.48 mm) with side-wettable flanks for AOI-compatible reflow soldering.

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; connected to higher potential (e.g., V_CC) in common-emitter switch configurations.
3	Collector (C)	Current sink terminal; delivers load current to ground or lower-potential node when saturated.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive applications including engine control modules and body electronics.
Side-wettable flanks	Enables automated optical inspection (AOI) of solder joint integrity on bottom-side terminals.
Low profile (0.48 mm height)	Reduces board stack height in ultra-thin consumer and portable industrial devices.
Three h_FE grades	BC807-40QB-Q offers highest gain (250–600), enabling tighter bias tolerance in precision analog stages.
Thermal enhancement	460 mW power rating on standard 70 μm FR4 improves reliability over legacy SOT-23 equivalents.

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 (Nexperia)	Same silicon, but in legacy SOT-23 package (3.0 × 1.4 × 1.1 mm); no side-wettable flanks; R_th(j-a) = 350 K/W.	Lacks AOI support and thermal performance; suitable only where board space and reflow inspection are non-critical.	Select only if legacy footprint compatibility outweighs AOI and thermal advantages of BC807-40QB-Q.
MMBT3906LT1G (onsemi)	−40 V V_CEO, −200 mA I_C, h_FE = 100–300; SOT-23 package; not AEC-Q101 qualified.	Lower voltage/current rating and no automotive qualification; limited to commercial-grade consumer applications.	Choose only for cost-sensitive, non-automotive designs where 200 mA load current suffices.

Compared with BC807-40,115, BC807-40QB-Q delivers 27% lower thermal resistance and AOI capability; versus MMBT3906LT1G, it provides +12.5% higher V_CEO, 2.5× higher I_C, and certified automotive readiness - critical for functional safety margins.

FAQ

What is the maximum allowable junction temperature for BC807-40QB-Q?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in Table 6 of the Nexperia datasheet. Operation beyond this limit risks permanent degradation of h_FE and increased leakage. Derating begins at T_amb > 25 °C per Figure 1, with P_tot dropping to zero at 150 °C ambient on 70 μm FR4.

Does BC807-40QB-Q support automatic optical inspection (AOI)?

Yes - its DFN1110D-3 package includes side-wettable flanks (SWF), explicitly designed for AOI of solder joints on the bottom-side terminals. This feature is confirmed in Section 2 (Features and benefits) and Figure 16 of the datasheet, enabling high-yield automated assembly in automotive manufacturing lines.

How does the h_FE of BC807-40QB-Q vary with temperature and current?

Per Figure 12, h_FE remains within 250–600 across −55 °C to 150 °C at I_C = −100 mA and V_CE = −1 V. At I_C = −500 mA, h_FE drops to ≥40 (Table 8), and decreases ~0.5%/°C above 25 °C due to carrier mobility reduction - a characteristic confirmed in the "Characteristics" section.

Is BC807-40QB-Q pin-compatible with BC807-40,115?

No - BC807-40QB-Q uses the DFN1110D-3 (SOT8015) package with 0.65 mm pitch and side-wettable flanks, while BC807-40,115 uses SOT-23 with 1.9 mm pitch and gull-wing leads. Footprint, soldering process, and thermal design are incompatible; migration requires PCB redesign and requalification.
