Product details
Overview
BC807-40-QR from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 (TO-236AB) 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 serves as a low-voltage switching or linear amplification device in automotive body control modules, LED driver stages, and power rail enable circuits.
For engineers reviewing the BC807-40-QR datasheet, BC807-40-QR pinout, BC807-40-QR application, or BC807-40-QR equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SOT23 pin mapping, and validated automotive-grade alternatives - all grounded in Nexperia's official Rev. 1 product data sheet dated 4 June 2021.
Technical Context
This transistor operates as a single-element PNP BJT with base-controlled current amplification. Its hFE range (250–600) supports stable biasing across temperature (−55 °C to +150 °C), while VCE(sat) ≤ −700 mV at IC = −500 mA / IB = −50 mA enables efficient low-side switching in 5 V and 3.3 V logic-driven loads.
Thermal resistance Rth(j-a) is 500 K/W on standard FR4 PCB and improves to 362 K/W with 1 cm² collector pad - directly informing layout-dependent power handling up to 250 mW at 25 °C ambient. The device meets AEC-Q101 stress test requirements for automotive use, including temperature cycling, HTRB, and ESD robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V: Maximum safe collector-emitter voltage with open base; defines upper rail limit for 36 V automotive systems. |
| IC | −500 mA continuous: Sustained load current capability without thermal runaway on standard PCB layout. |
| hFE | 250–600 at VCE = −1 V, IC = −100 mA: Ensures reliable base drive margin for switch saturation in noise-immune digital interfaces. |
| VCE(sat) | ≤ −700 mV at IC = −500 mA, IB = −50 mA: Minimizes conduction loss in high-duty-cycle switching applications like fan control. |
| Ptot | 250 mW at Tamb ≤ 25 °C (standard footprint): Sets maximum dissipation before thermal derating begins. |
| fT | 80 MHz: Supports small-signal amplification up to audio band and fast edge response in pulse-width modulation drivers. |
| Rth(j-a) | 500 K/W (standard FR4): Enables thermal modeling for board-level reliability in under-hood environments. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 1.3 mm × 2.9 mm footprint, 1.1 mm height, and gull-wing terminations compatible with reflow and wave soldering per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires ≥12 mA drive for full saturation at 500 mA load. |
| 2 | Emitter (E) | Common reference terminal tied to higher potential rail; carries full load current and sets VBE bias path. |
| 3 | Collector (C) | Output current sink node; connected to load return path; thermally coupled to PCB copper for heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood operation including temperature cycling, HTRB, and ESD (HBM ≥ 2 kV). |
| Three hFE grades | BC807-40-Q provides highest gain bin (250–600), enabling reduced base drive current vs. -16-Q or -25-Q variants. |
| Low VCE(sat) | ≤ −700 mV ensures <100 mW conduction loss at 500 mA, critical for thermally constrained PCBs. |
| High fT | 80 MHz transition frequency supports clean signal integrity in PWM dimming and sensor interface buffering. |
| Standard SOT23 footprint | Enables drop-in replacement with BC807-16-Q/BC807-25-Q and compatibility with existing pick-and-place tooling. |
Applications
| Automotive Door Module Switching | Industrial LED Driver Stage |
|---|---|
Use Scenario: Controlling window lift motor enable lines and mirror fold/unfold relays in door ECUs. IC Role / Device Role / Timing Role: PNP switch sinking current from microcontroller GPIO to ground-referenced load.

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 electrical specs and SOT23 package; differs only in tape/reel packaging (115 = 3,000 pcs/reel vs. QR = 10,000 pcs/reel). | No functional difference; identical in circuit design, layout, and thermal performance. | Select when volume procurement favors standard reel size over custom packaging. |
| MMBT3906LT1G | Lower hFE (100–300), higher VCE(sat) (≤ −400 mV @ IC = −100 mA), same −40 V rating and SOT23 footprint. | Less suitable for high-gain switching at 500 mA; better for low-current (<100 mA) signal inversion where gain consistency is secondary. | Choose only if legacy design uses MMBT3906LT1G and redesign is not feasible; verify hFE margin at operating point. |
Compared with BC807-40-QR, BC807-40,115 offers identical performance with standardized reel logistics, while MMBT3906LT1G trades gain and saturation voltage for broader legacy compatibility - making the QR variant optimal for new AEC-Q101-compliant designs requiring high-current, low-loss PNP switching.

FAQ
Is BC807-40-QR pin-compatible with BC807-16-Q and BC807-25-Q?
Yes - all BC807-Q series variants share identical SOT23 pinout (1: Base, 2: Emitter, 3: Collector), mechanical dimensions, and thermal characteristics. Only hFE bin differs: BC807-40-Q offers 250–600 versus 100–250 (−16-Q) and 160–400 (−25-Q), enabling direct substitution where higher gain is beneficial.
What is the maximum allowable junction temperature during operation?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation. Derating begins at 25 °C ambient, with Ptot decreasing linearly to zero at 150 °C junction temperature - confirmed by Figure 1 in the datasheet.
Does BC807-40-QR support wave soldering?
Yes - Nexperia specifies wave soldering footprints in Figure 18 (sot23_fw), with recommended land pattern dimensions of 2.8 mm × 4.5 mm and 1.4 mm × 1.2 mm pad spacing. Thermal mass and solder wettability are validated for lead-free processes per J-STD-020.
How does AEC-Q101 qualification impact design validation for non-automotive use?
AEC-Q101 qualification ensures enhanced robustness against temperature cycling, humidity, and ESD - providing superior reliability margins even in industrial or medical applications. It does not imply automotive-specific features, but confirms extended lifetime and failure-rate predictability under harsh conditions.
