Nexperia USA Inc. BC806-25WF

Overview

BC806-25WF from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) package, rated for −80 V V_CEO, −500 mA continuous collector current, and offering h_FE of 160–400 at V_CE = −1 V and I_C = −100 mA. It serves as a compact, AEC-Q101-qualified switching and amplification device in space-constrained automotive and industrial control circuits.

For engineers reviewing the BC806-25WF datasheet, BC806-25WF pinout, BC806-25WF application, or BC806-25WF equivalent, this page delivers verified package mapping, thermal derating curves, saturation voltage behavior across temperature, pulsed current capability, and direct comparison with BC806-16WF and BC816-25WF alternatives.

Technical Context

This PNP transistor operates with open-base collector-emitter breakdown voltage of −80 V and emitter-base breakdown voltage of −8 V, supporting robust operation in 48 V automotive board nets. Its DC current gain spans 160–400 under standardized test conditions (V_CE = −1 V, I_C = −100 mA), enabling predictable biasing in linear and saturated switching modes.

Thermal resistance from junction to ambient is 431 K/W when mounted on FR4 PCB with 1 cm² collector pad, and power dissipation is derated linearly above 25 °C ambient - reaching 0 mW at 150 °C junction temperature. Peak collector current reaches −1 A for ≤1 ms pulses, while base-emitter saturation voltage remains ≤−1.2 V at I_C = −500 mA.

FAQ

Is BC806-25WF suitable for linear amplification applications?

Yes - its specified h_FE of 160–400 at V_CE = −1 V and I_C = −100 mA, combined with low V_CE(sat) and stable gain vs. temperature curves (Fig. 8), supports Class-A and emitter-follower configurations. Designers should verify thermal limits using R_th(j-a) = 431 K/W and ensure junction temperature stays below 150 °C under operating bias.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA for ≤1 ms pulses, but continuous base current must be limited to maintain I_C ≤ −500 mA and T_j ≤ 150 °C. At I_C = −500 mA and h_FE = 160, minimum required I_B is −3.125 mA; practical design uses −10 mA to ensure saturation across temperature and process variation.

Does BC806-25WF support wave soldering?

Yes - Nexperia provides dedicated wave soldering footprint data (Fig. 14) with 3.65 mm × 2.1 mm land pattern and 1.425 mm × 0.9 mm solder resist openings. The SOT323 package is qualified for both reflow and wave processes per J-STD-020 and IPC-7095, provided preheat and dwell times respect thermal limits.

How does BC806-25WF differ from BC806-25W?

BC806-25WF is the RoHS-compliant, halogen-free variant of BC806-25W, with identical electrical specifications, package dimensions, pinout, and AEC-Q101 qualification. The "F" suffix denotes compliance with Nexperia's environmental policy (IEC 61249-2-21), including bromine <900 ppm and chlorine <900 ppm in homogeneous materials.
