Diodes Incorporated BAV16WS-7

Overview

BAV16WS-7 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 high-speed signal routing and clamping device in digital logic interfaces, sample-and-hold circuits, and low-power DC-DC converter snubbers.

For engineers reviewing the BAV16WS-7 datasheet, BAV16WS-7 pinout, BAV16WS-7 application, or BAV16WS-7 equivalent, key selection criteria include reverse recovery time under 4 ns, forward voltage ≤0.855 V at 10 mA, junction-to-ambient thermal resistance of 625 °C/W, and SOD323 footprint compatibility with high-density PCB layouts.

Technical Context

The BAV16WS-7 implements a planar epitaxial silicon PN junction optimized for rapid carrier recombination, enabling sub-4 ns reverse recovery under standardized 10 mA IF/IR test conditions. Its low 2.0 pF junction capacitance at 0 V bias supports high-frequency signal integrity in RF detector and clock line clamping roles.

Thermally, it operates across –55 °C to +150 °C with a 200 mW power dissipation limit on FR-4 board (1-inch², 2 oz Cu), derating linearly above 25 °C ambient per Figure 1. The cathode band marking and matte tin-plated Alloy 42 leadframe ensure unambiguous polarity identification and reliable solderability.

FAQ

Is BAV16WS-7 electrically interchangeable with 1N4148WS-7-F?

Yes - both share identical SOD323 package, 4.0 ns reverse recovery time, 75 V VRRM, and 300 mA IFM ratings. Their forward voltage curves differ slightly below 1 mA, but functional interchangeability is confirmed across standard digital switching and clamping applications per Diodes' DS30097 Rev. 29.

What is the maximum operating temperature for continuous use?

The BAV16WS-7 is rated for continuous operation from –55 °C to +150 °C junction temperature. At +150 °C ambient, its 200 mW power dissipation must be reduced to ~80 mW per the derating curve in Figure 1, assuming standard FR-4 mounting with 1-inch² copper pad.

Does BAV16WS-7 meet automotive qualification requirements?

No - BAV16WS-7 is not AEC-Q101 qualified. For automotive use, Diodes specifies the BAV16WSQ-7-F variant, which undergoes AEC-Q101 stress testing, supports PPAP documentation, and is manufactured in IATF16949-certified facilities.

Can BAV16WS-7 replace BAT54 series Schottky diodes?

Only in applications where low forward voltage is noncritical and high-temperature reverse leakage must be minimized. BAT54 devices offer ~0.33 V VF but exhibit µA-level IR at elevated temperatures; BAV16WS-7 provides nA-level IR up to +150 °C, making it preferable for precision clamping where leakage-induced offset matters.
