Overview
The Vishay BAT54C-HE3_A-18 is a dual common cathode Schottky barrier diode in an SOT-23 package. It features a repetitive peak reverse voltage of 30 V and a continuous forward current rating of 200 mA. The device exhibits low forward voltage, with a maximum of 800 mV at 100 mA, and a leakage current of 2 µA at 25 V reverse bias. Operating temperature ranges from -55 °C to +125 °C, with a storage range up to +150 °C. It includes PN junction guard ring protection against electrostatic discharge.
Feature Summary
- Dual common cathode configuration for efficient circuit integration
- PN junction guard ring provides protection against excessive voltage stress
- Low forward voltage drop minimizes conduction losses
- Fast switching characteristics suitable for high-speed applications
Applications
- Ultra-high-speed switching circuits
- Voltage clamping applications
- Reverse polarity protection
- Line termination
Procurement Notes
Verify the specific HE3 suffix confirms AEC-Q101 automotive qualification status as defined by Vishay. Confirm the _A-18 suffix corresponds to the 10,000 units per reel packaging option on 13-inch reels. Ensure compliance with UL 94 V-0 flammability ratings and RoHS requirements during procurement validation.
Selection Notes
Select this component when a dual common cathode Schottky diode is required within an SOT-23 footprint. The HE3 designation indicates AEC-Q101 qualification, making it suitable for automotive environments. Consider the 30 V reverse voltage and 200 mA forward current limits to ensure adequate headroom for the target application's electrical demands.
Part Context
This part belongs to the Vishay BAT54 series of small signal Schottky diodes. The series includes single, common anode, common cathode, and dual serial configurations. The BAT54C variant specifically utilizes a dual common cathode topology. The HE3 product line represents Vishay's lead-free, environmentally compliant offerings that meet stringent automotive reliability standards.
Replacement Considerations
BAT54C-E3-18 serves as the commercial grade alternative without AEC-Q101 qualification. Other BAT54 variants like BAT54S or BAT54A offer different internal circuit topologies but share similar physical packages and general performance characteristics.
