Description
BAT46 is a widely used small-signal Schottky diode (2-terminal) in the BAT46 family. It combines a very low forward voltage and fast switching, which makes it ideal for high-speed and RF circuits.
Key points:
- Forward voltage: typically ~0.2–0.3 V at low to moderate current.
- Reverse voltage: varies by variant, commonly tens of volts (check datasheet for exact rating).
- Forward current: generally in the few hundred mA range (depends on package/variant).
- Characteristics: fast switching, low junction capacitance, no significant reverse recovery.
Common applications:
- RF/high-speed detectors and demodulators
- Envelope detectors and limiter/clipping circuits
- Logic-level shifting and protection in tuners/mixers
Package/variants:
- SMD packages (e.g., small footprints like SOD-123/SOD-323); several variants with different ratings (check exact datasheet for the variant you choose).
Tip: Always verify the exact BAT46 variant you’re using (voltage, current, and package) from the datasheet for your design.
