Nexperia USA Inc. BC807W,115

Overview

BC807W,115 from Nexperia is a PNP 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 100–600 at V_CE = −1 V and I_C = −100 mA. It serves as a general-purpose switching and amplification device in low-power analog and digital interface circuits, including level-shifting stages in microcontroller I/O drivers.

For engineers reviewing the BC807W,115 datasheet, BC807W,115 pinout, BC807W,115 application, or BC807W,115 equivalent, key selection criteria include its PNP polarity, SOT323 thermal derating profile (R_th(j-a) = 625 K/W on FR4), −700 mV V_CEsat at −500 mA/−50 mA drive, and marking code "5D%" for traceability.

Technical Context

The BC807W,115 operates as a silicon PNP BJT with base-controlled current amplification, optimized for linear amplification and saturated switching in ambient temperatures from −65 °C to 150 °C. Its absolute maximum ratings include −50 V V_CBO, −5 V V_EBO, and 290 mW P_tot with 1 cm² collector pad on FR4 PCB.

Thermal performance is defined by transient impedance curves (Fig. 2–3) and power derating above 25 °C (Fig. 1), while electrical behavior follows standard Ebers-Moll model characteristics-evidenced by h_FE variation across I_C (Fig. 4), V_CEsat vs. I_C (Fig. 6), and V_BE temperature coefficient of −2 mV/K.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA per Table 6, but continuous operation must stay within the thermal limits of the package. At Tamb = 25 °C, the device dissipates up to 290 mW with a 1 cm² collector pad; sustained I_B > −50 mA risks exceeding T_j = 150 °C unless board-level thermal design compensates. Derating curves in Fig. 1 apply.

Can BC807W,115 replace BC807-40W in a circuit?

Yes, electrically-both share identical V_CEO, I_C, package, and pinout-but BC807-40W has higher minimum h_FE (250 vs. 100). If the original design relies on guaranteed h_FE ≥ 250 for reliable saturation at light loads, BC807W,115 may require base resistor reduction to maintain I_B/I_C ≥ 10 across the full 100–600 range.

Is BC807W,115 qualified for automotive applications?

No. Per Revision History (Table 9), BC807W_SER was explicitly changed to non-automotive qualification in Rev. 8 (2022). Automotive use requires Nexperia's −Q qualified variants such as BC807W-Q, which undergo AEC-Q101 stress testing and have different reliability documentation and traceability protocols.

What does the marking code "5D%" indicate on the device body?

"5D%" is the top-side laser marking per Table 5: "5D" identifies the BC807W variant, and "%" is a placeholder for the manufacturing site code (e.g., "A" for Nijmegen, "B" for Bangkok). This code enables lot traceability and confirms authenticity when cross-referenced with Nexperia's official marking guide PN2001.
