Product details

Overview

BC807-40W-QF from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) 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 supports automotive-grade switching and amplification in space-constrained PCB layouts.

For engineers reviewing the BC807-40W-QF datasheet, BC807-40W-QF pinout, BC807-40W-QF application, or BC807-40W-QF equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, SOT323 footprint details, and validated automotive use cases - all directly traceable to Nexperia's official product data sheet Rev. 1 (June 2021).

Technical Context

This PNP transistor operates with open-base collector-emitter breakdown voltage of −45 V and emitter-base breakdown voltage of −5 V, enabling reliable operation in low-voltage negative-rail switching circuits. Its pulsed h_FE range (250–600) and −700 mV V_CE(sat) at I_C = −500 mA / I_B = −50 mA support efficient saturation-mode control in digital logic interfaces and load switching.

Thermal resistance R_th(j-a) is 431 K/W when mounted on FR4 PCB with 1 cm² collector pad, and 625 K/W under standard footprint conditions - critical for thermal design in automotive cabin modules and industrial sensor nodes where ambient temperatures reach 125 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V: Maximum safe collector-emitter voltage with base open; defines rail compatibility in −12 V or −24 V systems.
I_C	−500 mA continuous: Supports medium-power loads such as LED drivers, relay coils, and small solenoids.
h_FE	250–600 at V_CE = −1 V, I_C = −100 mA: Enables precise base drive sizing for predictable switching thresholds.
V_CE(sat)	−700 mV max at I_C = −500 mA, I_B = −50 mA: Minimizes conduction loss and self-heating in high-duty-cycle applications.
P_tot	290 mW with 1 cm² collector pad: Sets practical power handling limit for thermally constrained SMT layouts.
f_T	80 MHz: Supports signal amplification up to audio frequencies and fast digital edge transitions.
R_th(j-a)	431 K/W (optimized layout): Determines junction temperature rise under sustained load - essential for AEC-Q101 reliability validation.

Pinout & Package

SOT323 (SC-70) surface-mount plastic package: 3-terminal, ultra-small outline (2.2 mm × 1.35 mm × 0.95 mm), optimized for high-density automotive PCBs and portable electronics.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires ≤ −50 mA drive for full saturation at −500 mA collector load.
2	Emitter (E)	Common reference terminal tied to negative supply rail; carries full load current and sets V_BE bias point.
3	Collector (C)	Output terminal connected to load; thermally coupled to PCB copper for heat dissipation per JEDEC SC-70 layout guidelines.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including body control modules and HVAC actuators per stress test requirements.
Three h_FE variants	BC807-40W-Q provides highest gain bin (250–600), reducing required base drive current versus -16W-Q or -25W-Q versions.
Low V_CE(sat)	−700 mV max enables <150 mW conduction loss at full rated current - critical for thermally isolated modules.
SOT323 footprint	Compatible with standard reflow soldering profiles (Fig. 17); 0.65 mm pitch allows placement adjacent to fine-pitch ICs.
High f_T	80 MHz transition frequency supports stable operation in active filters and low-noise preamplifier stages.

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	No AEC-Q101 qualification; identical electrical specs and SOT23 package (larger than SOT323).	Not approved for automotive use; suitable only for commercial-grade consumer or industrial equipment.	Select when cost sensitivity outweighs automotive compliance and board space permits SOT23 footprint.
MMBT3906LT1G	Lower h_FE (100–300), same −40 V V_CEO, −200 mA I_C, and SOT23 package.	Limited to low-current signal switching; insufficient for 500 mA loads like relays or multi-LED strings.	Choose only for sub-100 mA logic inversion or biasing where gain consistency is secondary.

Compared with BC807-40W-QF, BC807-40,115 trades automotive qualification for lower cost and larger package, while MMBT3906LT1G sacrifices current rating and gain for broader commercial availability - making BC807-40W-QF the sole option meeting AEC-Q101, SOT323 size, and −500 mA capability simultaneously.

FAQ

What is the maximum allowable junction temperature for BC807-40W-QF?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in Table 6 of the Nexperia datasheet Rev. 1. This limit applies under all operating conditions and must be respected to maintain AEC-Q101 reliability. Thermal design must ensure T_j remains below this value using the specified R_th(j-a) values and PCB copper area guidelines.

Is BC807-40W-QF pin-compatible with BC807-40,115?

No - BC807-40W-QF uses SOT323 (SC-70) package with 0.65 mm lead pitch, while BC807-40,115 uses SOT23 with 0.95 mm pitch. The pin order (Emitter-Base-Collector) is identical, but physical mounting and solder stencil design differ significantly. Board redesign is required for substitution.

Does BC807-40W-QF support pulsed operation beyond its DC current rating?

Yes - the datasheet specifies I_CM = −1 A for single pulses ≤1 ms, enabling short-duration surge handling (e.g., relay coil inrush). However, pulse duty cycle must remain ≤0.02 (2%) and pulse width ≤300 μs to stay within the pulsed h_FE test condition, as noted in Table 2 footnote [1].

How does the marking code '5C%' identify BC807-40W-QF on the device?

The top-side marking is '5C%', where '5C' is the unique identifier for BC807-40W-QF per Table 5, and '%' is a placeholder for the manufacturing site code. This matches Nexperia's standardized SOT323 marking scheme and distinguishes it from BC807-16W-Q ('5A%') and BC807-25W-Q ('5B%').
