L43 Marking BAT54C SOT-23 30V 200mA Diode

L43 Marking BAT54C SOT-23 Schottky Diode

L43 Marking BAT54C SOT-23 is a compact planar Schottky diode rated at 30V reverse voltage and 200mA forward current. Designed for efficient low-power rectification, voltage clamping, and signal routing, it features a forward voltage drop of just 800mV at 100mA. Its SOT-23 package makes it ideal for densely packed surface-mount designs where space and thermal management are critical.

Engineered for fast-switching circuits, the BAT54C offers a reverse recovery time of only 5ns, making it suitable for high-frequency applications such as DC-DC converters, mobile electronics, and communication modules. The integrated PN junction guard ring enhances ESD and transient protection, boosting durability in sensitive environments. Operating reliably between -65°C and +150°C, and fully RoHS-compliant, this diode is a dependable choice for both consumer and industrial-grade applications.
