Technical Specifications and Datasheet Highlights

A deep dive into the datasheet reveals the key electrical characteristics that define this component's performance. The BAV99SH6327 is not a single diode but a common-cathode dual-diode array, integrating two independent diodes in one compact package, which saves significant PCB space and improves circuit layout efficiency.

The paramount specifications include:

Repetitive Peak Reverse Voltage (VRRM): 70 V

Average Forward Current (IFAV): 215 mA per diode

Peak Forward Surge Current (IFSM): 4 A (tp = 1 s)

Forward Voltage (VF): Typically 715 mV at IF = 10 mA, rising to 1 V at IF = 100 mA. This low VF is critical for minimizing power loss and heat generation.

Reverse Recovery Time (trr): A remarkably fast 4 ns (typical). This is the standout feature, defining its high-speed switching capability and its ability to operate efficiently in very fast circuits without introducing significant delay or noise.

Total Capacitance (Ct): Typically 2 pF at VR = 1 V, f = 1 MHz. Low junction capacitance is essential for maintaining signal integrity in high-frequency applications.

The device is characterized for operation over a junction temperature range from -65 °C to +150 °C, ensuring reliability under various environmental conditions. Its SMD package is also designed for compatibility with automatic assembly processes.
