BAT15-03WE6327: Technical Specifications and Application Notes

The BAT15-03WE6327 is a high-performance Schottky barrier diode, specifically engineered for applications requiring low forward voltage and ultra-fast switching speeds. As a critical component in surface-mount technology (SMT), this diode is housed in a compact SOD-323 (SC-76) package, making it ideal for space-constrained PCB designs.

Key Technical Specifications:

Diode Type: Schottky

Package: SOD-323 (SC-76)

Maximum Repetitive Reverse Voltage (VRRM): 15 V

Average Forward Current (IF(AV)): 30 mA

Peak Forward Surge Current (IFSM): 1 A

Forward Voltage (VF): 350 mV (typical at IF = 1 mA)

Reverse Recovery Time (trr): < 1 ns (extremely fast)

Operating and Storage Temperature Range: -65 °C to +150 °C

The defining characteristic of the BAT15-03WE6327 is its extremely low capacitance and fast switching capability. This is primarily due to the Schottky barrier principle, which is a metal-semiconductor junction that enables very high-speed operation by eliminating the charge storage effects seen in conventional PN-junction diodes. Its low forward voltage drop ensures minimal power loss and higher efficiency in circuits.

Primary Application Notes:

The BAT15-03WE6327 excels in high-frequency signal processing and precision detection circuits. Its primary applications include:

1. Mixers and Detectors: The diode's fast switching and low distortion make it a premier choice for RF mixers and demodulators in communication systems, including satellite receivers, radar detectors, and industrial sensors. It is particularly effective in balanced mixer configurations for frequency conversion.

2. Sample-and-Hold Circuits: The low forward voltage and minimal charge storage allow for accurate and rapid sampling of analog signals.

3. High-Speed Switching and Clamping: It is used for protecting sensitive IC inputs from voltage transients and for clipping signals in high-speed digital interfaces.

4. Signal Demodulation: Its ability to rectify very high-frequency signals makes it suitable for demodulating amplitude-modulated (AM) signals.

When implementing the BAT15-03WE6327, careful PCB layout is crucial. Minimizing parasitic inductance and capacitance by using short, direct traces is essential to maintain its high-frequency performance. Furthermore, while it has a low reverse leakage current for a Schottky diode, this parameter must be considered in high-temperature, low-power applications.
