Product details
Overview
BC807-40QCH-Q from Nexperia is a PNP general-purpose transistor in a DFN1412D-3 (SOT8009) leadless SMD package, rated for −45 V VCEO, −500 mA IC, and DC current gain (hFE) of 250–600 at VCE = −1 V and IC = −100 mA. It supports automotive-grade operation up to 175 °C junction temperature and features side-wettable flanks for AOI-compatible solder joint inspection. Used in space-constrained switching and amplification circuits such as LED drivers and load switches in automotive body control modules.
For engineers reviewing the BC807-40QCH-Q datasheet, BC807-40QCH-Q pinout, BC807-40QCH-Q application, or BC807-40QCH-Q equivalent, key selection criteria include its AEC-Q101 qualification, ultra-thin 0.5 mm profile, high hFE binning, thermal performance on FR4 PCBs, and compatibility with reflow soldering per SOT8009 footprint guidelines.
Technical Context
This PNP bipolar junction transistor operates with open-base collector-emitter breakdown voltage of −45 V and emitter-base breakdown voltage of −5 V, enabling robust biasing in low-voltage automotive subsystems. Its pulsed peak collector current capability reaches −1 A (tp ≤ 1 ms), supporting transient load handling in power management nodes.
The device delivers VCE(sat) ≤ −700 mV at IC = −500 mA and IB = −50 mA, ensuring low conduction loss in saturated-switch applications. Thermal resistance Rth(j-a) is 261 K/W on 70 μm copper FR4, enabling reliable operation at ambient temperatures up to +175 °C when properly mounted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - Maximum safe collector-emitter voltage under open-base conditions; defines upper rail limit in PNP switch designs. |
| IC | −500 mA - Continuous DC collector current rating; sets maximum steady-state load drive capability. |
| hFE | 250–600 - DC current gain at VCE = −1 V, IC = −100 mA; enables precise base current sizing for predictable saturation. |
| VCE(sat) | ≤ −700 mV - Collector-emitter saturation voltage at IC = −500 mA, IB = −50 mA; minimizes power loss in on-state switching. |
| Tj(max) | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments without derating. |
| Ptot | 575 mW - Total power dissipation on FR4 with 70 μm copper; determines thermal layout requirements for board-level reliability. |
| Rth(j-a) | 261 K/W - Junction-to-ambient thermal resistance on standard FR4; used to calculate temperature rise under load. |
Pinout & Package
BC807-40QCH-Q uses the DFN1412D-3 (SOT8009) package: 1.4 mm × 1.2 mm × 0.5 mm body, leadless, with side-wettable flanks for automated optical inspection. Package complies with MO-340CA and is qualified for reflow soldering per JEDEC J-STD-020.
| 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 rail in common-emitter switching configurations. |
| 3 | Collector (C) | Current sink terminal; delivers load current to ground or lower-potential node when saturated. |
Key Features

| AEC-Q101 qualified | Validated for automotive applications including body electronics and lighting control; ensures reliability over 15-year vehicle lifetime. |
| Side-wettable flanks | Enables 100% automated optical inspection (AOI) of solder joints without X-ray; reduces post-solder defect escapes in high-volume production. |
| Ultra-thin 0.5 mm height | Reduces Z-axis stack-up in multi-layer PCB assemblies; critical for compact infotainment and ADAS sensor modules. |
| Three hFE bins | BC807-40QCH-Q provides tight 250–600 gain spread, simplifying base resistor selection and improving batch-to-batch consistency in analog amplifiers. |
| High-temp operation | Rated for continuous operation at Tamb = +175 °C; eliminates need for external thermal derating in engine bay or powertrain proximity layouts. |

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 | Same die, but in SOT23 package (3.0 mm × 1.4 mm × 1.1 mm); no side-wettable flanks; Rth(j-a) = 329 K/W (35 μm FR4). | Lacks AOI support and thermal performance; suitable only for non-automotive, cost-sensitive consumer boards. | Select only if AOI is not required and board space allows larger footprint; avoid for AEC-Q101 programs. |
| MMBT3906LT1G | −40 V VCEO, −200 mA IC, hFE = 100–300; SOT23 package; not AEC-Q101 qualified. | Lower voltage/current ratings and unqualified for automotive use; limited to commercial-grade signal switching. | Use only in non-safety-critical, low-power applications where BC807-40QCH-Q's performance headroom is unnecessary. |
Compared with BC807-40,115 and MMBT3906LT1G, BC807-40QCH-Q uniquely combines AEC-Q101 qualification, side-wettable flanks for AOI, and superior thermal performance in a 40% smaller footprint-making it the only choice for space-constrained, high-reliability automotive and industrial switching.

FAQ
What is the marking code for BC807-40QCH-Q?
The top-side marking for BC807-40QCH-Q is "8U", laser-etched on the package surface. This code is defined in Table 5 of the official Nexperia datasheet Rev. 1 (25 January 2022) and distinguishes it from BC807-16QCH-Q ("8S") and BC807-25QCH-Q ("8T"). No other marking variants are specified or qualified for this part number.
Does BC807-40QCH-Q support lead-free reflow soldering?
Yes, BC807-40QCH-Q is qualified for lead-free reflow soldering per JEDEC J-STD-020. The recommended profile uses peak temperatures up to 260 °C, with a maximum time above liquidus of 60 seconds. Figure 17 in the datasheet provides the exact SOT8009 footprint and stencil recommendations, including 0.1 mm stencil thickness and 0.4 mm solder paste aperture width.
How does the DFN1412D-3 package improve thermal performance over SOT23?
DFN1412D-3 achieves Rth(j-a) = 261 K/W on 70 μm FR4 versus ~329 K/W for SOT23, due to its exposed thermal pad and direct copper contact. The 0.5 mm height also improves airflow and reduces thermal mass. These attributes enable 23% higher power dissipation at the same ambient temperature, critical for automotive under-hood applications.
Is BC807-40QCH-Q suitable for linear amplifier applications?
Yes - its hFE of 250–600 at IC = −100 mA and low VBE drift (−2 mV/K) support stable biasing in Class A and AB amplifier stages. However, linear operation must remain within the Safe Operating Area (SOA) limits: VCE ≤ −45 V, IC ≤ −500 mA, and power ≤ 575 mW at Tamb = 25 °C, with appropriate derating above that temperature.
