Diodes Incorporated BAV16WS-7-F

Overview

BAV16WS-7-F from Diodes Incorporated is a surface-mount fast switching diode in SOD323 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It serves as a general-purpose signal-level switching and clamping device in high-speed digital logic interfaces, ESD protection networks, and sample-and-hold circuits.

For engineers reviewing the BAV16WS-7-F datasheet, BAV16WS-7-F pinout, BAV16WS-7-F application, or BAV16WS-7-F equivalent, key selection criteria include reverse recovery time, forward voltage at 10 mA, peak reverse leakage at 150°C, junction-to-ambient thermal resistance, and SOD323 footprint compatibility with high-density PCB layouts.

Technical Context

This diode implements a planar epitaxial silicon PN junction optimized for low charge storage and rapid carrier recombination. Its 4.0 ns t_RR is measured under standardized IF = IR = 10 mA, I_RR = 0.1 × I_R, R_L = 100 Ω conditions, enabling reliable operation in 10–50 MHz clocked switching nodes.

The SOD323 package features matte tin-plated alloy 42 leadframe, J-STD-020 Level 1 moisture sensitivity, and UL 94V-0 molded plastic housing. Polarity is indicated by a cathode band; total capacitance is 2.0 pF at 0 V reverse bias and 1 MHz.

FAQ

Is BAV16WS-7-F AEC-Q101 qualified?

No. BAV16WS-7-F is not AEC-Q101 qualified. The automotive-grade variant is BAV16WSQ-7-F, which carries AEC-Q101 qualification, PPAP capability, and is manufactured in IATF16949-certified facilities. Standard BAV16WS-7-F is intended for commercial and industrial applications.

What is the maximum forward surge current rating?

BAV16WS-7-F supports a non-repetitive peak forward surge current of 4.0 A for t = 1.0 µs and 1.0 A for t = 1.0 s, per the DS30097 datasheet. These ratings assume no self-heating effects dominate and are validated using short-pulse testing methods.

Does BAV16WS-7-F have a specified junction capacitance vs. reverse voltage curve?

Yes. Figure 4 in DS30097 shows typical total capacitance decreasing from ~2.0 pF at 0 V to ~0.7 pF at 20 V reverse bias, measured at 1 MHz. This voltage-dependent C_T behavior is documented across –40°C to +150°C ambient conditions.

Can BAV16WS-7-F replace 1N4148 through-hole diodes in new designs?

Yes, provided PCB layout accommodates the SOD323 footprint. While electrically equivalent to 1N4148 in speed and voltage rating, BAV16WS-7-F is surface-mount only and lacks axial-lead mechanical form factor. It is not a drop-in replacement for through-hole assembly but is a direct functional upgrade for SMT-based designs.
