BAT41 Schottky Diode 100V 100mA DO-35 Small Signal High-Speed Switching Diode for RF, Clipping & Signal Circuits (Low Current, Not for Power Rectification)

The BAT41 from STMicroelectronics is a small-signal Schottky diode designed for high-speed switching, RF applications, signal detection, and low-current rectification. With very low capacitance and fast response time, it is commonly used in high-frequency circuits, protection clamps, logic-level switching, and analog signal processing.

Unlike power Schottky diodes such as the 1N5819, the BAT41 is intended strictly for low-current signal applications and should not be used in power supply rectification or high-load circuits.

• Schottky small-signal diode
• 100V reverse voltage rating
• 100mA maximum average forward current
• Very low forward voltage (~450mV @ 1mA)
• Extremely low junction capacitance (~2pF)
• DO-35 axial glass package
• High-speed switching performance
• Ideal for RF, detector, clipping, and protection circuits
• Low leakage current (100 nA @ 50V)
• Common in signal processing and analog electronics
• Manufacturer: STMicroelectronics
• Manufacturer Part Number: BAT41

⚠️ Important: This is a low-current signal diode and is NOT interchangeable with power rectifier diodes like the 1N5819 (1A power Schottky used in power supplies and reverse polarity protection).
