Nexperia USA Inc. BC807-16QBZ

Overview

BC807-16QBZ from Nexperia is a PNP general-purpose bipolar junction transistor in a leadless DFN1110D-3 (SOT8015) package, rated for −45 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 100–250 at V_CE = −1 V and I_C = −100 mA. It serves as a compact, surface-mount switching and amplification device in space-constrained consumer and industrial PCBs.

For engineers reviewing the BC807-16QBZ datasheet, BC807-16QBZ pinout, BC807-16QBZ application, or BC807-16QBZ equivalent, this part supports AOI-compatible solder joint inspection, delivers low saturation voltage (−700 mV max at I_C = −500 mA / I_B = −50 mA), and operates across −55 °C to +150 °C ambient temperature with side-wettable flanks for reliable reflow yield.

Technical Context

This PNP BJT features a planar epitaxial die structure optimized for stable DC current gain across temperature and collector current ranges. Its DFN1110D-3 package integrates side-wettable flanks for automated optical inspection of solder fillets and enables thermal resistance of 272 K/W on 70 μm FR4 copper.

The device exhibits typical transition frequency (f_T) of 80 MHz at V_CE = −5 V, I_C = −10 mA, and 100 MHz test frequency, with collector capacitance (C_c) of 5 pF at V_CB = −10 V - confirming suitability for low-to-moderate speed switching up to several megahertz.

FAQ

What is the maximum allowable peak collector current for BC807-16QBZ?

The absolute maximum peak collector current (I_CM) is −1 A for single pulses ≤1 ms at T_amb = 25 °C. This rating supports brief inrush current handling in relay or capacitor charging applications, provided average power remains within the 460 mW total dissipation limit on 70 μm FR4 copper.

Does BC807-16QBZ require special reflow profile considerations due to its DFN package?

Yes - the DFN1110D-3 package requires adherence to the recommended reflow footprint (0.34 mm × 0.34 mm solder lands, 0.1 mm stencil thickness) and peak temperature ≤260 °C per JEDEC J-STD-020. Side-wettable flanks enable post-reflow AOI, but insufficient solder paste volume or misalignment causes voiding or non-wetting.

How does the h_FE variation affect base resistor selection in switching applications?

With h_FE ranging from 100 to 250, base resistors must ensure saturation across the full gain range. For I_C = −500 mA, designing for h_FE(min) = 100 yields I_B = −5 mA, requiring ≤680 Ω at 3.3 V drive - guaranteeing hard saturation even at worst-case gain and elevated temperature.

Can BC807-16QBZ be used in linear amplification mode?

Yes - its f_T of 80 MHz and low distortion characteristics support Class-A audio preamplifier stages and sensor signal conditioning. However, linear operation demands strict thermal management: at 200 mW dissipation, junction temperature rise exceeds 54 °C above ambient on standard FR4, necessitating layout-aware copper pour or derating above 70 °C ambient.
