Product details
Overview
BC807-40QAZ from Nexperia is a 45 V, −500 mA PNP general-purpose transistor in a leadless DFN1010D-3 (SOT1215) package, AEC-Q101 qualified for automotive use, with DC current gain (hFE) of 250–600 at VCE = −1 V and IC = −100 mA, used for low-profile switching in mobile power management circuits.
For engineers reviewing the BC807-40QAZ datasheet, BC807-40QAZ pinout, BC807-40QAZ application, or BC807-40QAZ equivalent, this device serves as a compact, thermally enhanced PNP switch in space-constrained automotive and portable electronics where low height (0.37 mm), high reliability, and defined gain binning are critical selection criteria.
Technical Context
This PNP bipolar junction transistor operates in active or saturation mode for signal-level and medium-power switching. Its design supports stable DC biasing with tight hFE distribution (250–600), low VCE(sat) (≤ −700 mV at IC = −500 mA / IB = −50 mA), and robust thermal performance on FR4 PCBs.
The DFN1010D-3 package features solderable side pads and a 1.1 × 1.0 × 0.37 mm body, enabling high-density placement while maintaining 900 mW total power dissipation under 4-layer copper + 1 cm² collector pad conditions per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - Maximum safe collector-emitter voltage with base open; defines off-state blocking capability in switching applications. |
| IC | −500 mA - Continuous collector current rating; supports load switching up to half-ampere DC loads. |
| hFE | 250–600 - DC current gain range at VCE = −1 V, IC = −100 mA; enables predictable base drive sizing for reliable saturation. |
| VCE(sat) | ≤ −700 mV - Collector-emitter saturation voltage at IC = −500 mA / IB = −50 mA; minimizes conduction loss in high-duty-cycle switches. |
| Ptot | 900 mW - Max power dissipation with 4-layer FR4 PCB and 1 cm² collector pad; determines thermal headroom in compact layouts. |
| Rth(j-a) | 139 K/W - Junction-to-ambient thermal resistance under optimized 4-layer + 1 cm² mounting; informs temperature rise estimation. |
Pinout & Package
Package: DFN1010D-3 (SOT1215), ultra-thin 1.1 × 1.0 × 0.37 mm plastic package with visible and solderable side pads; no leads; thermally enhanced for surface-mount assembly.
| 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; connected to higher potential rail in high-side switch topologies. |
| 3 | Collector (C) | Current sink terminal; electrically tied to pin 4 in internal die layout; routed to load or ground return path. |
| 4 | Collector (C) | Redundant collector connection for improved current handling and thermal spreading; must be soldered to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards. |
| Low profile (0.37 mm height) | Enables stacking under shields or integration into ultra-thin handheld and ADAS modules without mechanical interference. |
| High hFE bin (250–600) | Reduces required base drive current by ~2× vs. BC807-25QA, lowering MCU GPIO loading and driver stage complexity. |
| Thermally enhanced DFN | Side pads and dual collector terminals improve heat transfer to PCB, supporting 900 mW dissipation with proper layout. |
Applications
| Automotive Door Module Switching | Portable Device LED Backlight Control |
|---|---|
|
Use Scenario: Driving resistive loads such as window motor relays or mirror actuator solenoids in door control units. IC Role / Device Role / Timing Role: High-side PNP switch controlling 12 V loads with MCU-compatible base drive. Use Value: AEC-Q101 qualification ensures lifetime reliability across −40 °C to +125 °C ambient, while low VCE(sat) reduces self-heating during frequent actuation cycles. |
Use Scenario: PWM-controlled current sink for white LED strings in smartphone or tablet displays. IC Role / Device Role / Timing Role: Linear or saturated PNP current regulator interfacing with low-voltage PWM controllers. Use Value: Tight hFE bin enables consistent LED current matching across units; 0.37 mm height allows placement beneath display flex assemblies. |

IC Role / Device Role / Timing Role: Low-loss PNP pass element in discrete OR-ing or enable circuitry. Use Value: −45 V VCEO provides margin against voltage transients; dual collector terminals reduce thermal impedance during sustained 500 mA operation. |
Use Scenario: Level-shifting and signal inversion for analog sensor outputs feeding microcontroller ADC inputs. IC Role / Device Role / Timing Role: Small-signal PNP amplifier or digital inverter stage in 3.3 V/5 V mixed-signal front-ends. Use Value: 80 MHz fT supports clean amplification of kHz-range sensor signals; low ICBO (≤ −100 nA) preserves precision in high-impedance bias networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC807-40,115 | Same silicon, but in SOT23 package (2.9 × 1.3 × 1.0 mm); no AEC-Q101 qualification; Rth(j-a) = 250 K/W (4-layer PCB). | Larger footprint and lower thermal performance; suitable for non-automotive consumer designs with less stringent reliability requirements. | Select when cost or legacy SOT23 compatibility outweighs size and automotive compliance needs. |
| MMBT4403LT1G | PNP transistor in SOT-23; VCEO = −40 V, IC = −600 mA, hFE = 100–300; not AEC-Q101 qualified; Rth(j-a) ≈ 300 K/W. | Higher current rating but wider hFE spread and inferior thermal performance; lacks automotive stress testing validation. | Choose only for non-automotive industrial or prototyping use where gain consistency and thermal margin are secondary. |
Compared with BC807-40QAZ, BC807-40,115 trades automotive qualification and ultra-low profile for broader distributor availability, while MMBT4403LT1G offers higher IC but sacrifices gain stability, thermal efficiency, and automotive reliability-making BC807-40QAZ optimal for space- and mission-critical automotive modules.

FAQ
Is BC807-40QAZ pin-compatible with BC807-40,115?
No. BC807-40QAZ uses the DFN1010D-3 (SOT1215) 4-terminal package with pins 1–2–3–4 assigned as B–E–C–C, while BC807-40,115 uses the 3-pin SOT23 package with pinout E–C–B. Footprint, soldering profile, and thermal pad requirements differ significantly-direct replacement requires PCB redesign.
What is the maximum allowable PCB copper area for optimal thermal performance?
For rated 900 mW dissipation, Nexperia specifies a 1 cm² tin-plated copper pad on a 4-layer FR4 PCB connected to both collector terminals (pins 3 and 4). Reducing pad area or layer count increases Rth(j-a)-e.g., single-sided copper yields only 300 mW rating-so full 1 cm² implementation is mandatory to achieve datasheet thermal limits.
Does BC807-40QAZ support pulsed operation beyond its DC ratings?
Yes. The datasheet specifies ICM = −1 A (peak collector current) and IBM = −200 mA (peak base current) for single pulses ≤1 ms. However, pulse duty cycle and thermal accumulation must be verified using the transient thermal impedance curves (Fig 4–6); sustained pulsing requires derating based on measured junction temperature.
How does the "QA" suffix relate to marking and traceability?
The "QA" suffix denotes AEC-Q101 qualification and corresponds to the binary marking code "00 11 00" laser-etched on the top of the DFN1010D-3 package. This code identifies the BC807-40QA variant and links to Nexperia's lot traceability system, enabling full process history retrieval for automotive audit compliance.
