BAT46AWFILM

Diode Arrays Overview

The BAT46AWFILM is a small signal Schottky diode manufactured by STMicroelectronics, designed for high-speed switching and rectification applications. It features a common anode double configuration housed in a compact SOT-323 surface-mount package. The device supports a maximum repetitive reverse voltage of 100 V and a continuous forward current of 150 mA. Key electrical characteristics include a low forward voltage drop of approximately 1 V at rated current and a minimal reverse leakage current of 5 uA. It operates within a temperature range of -65°C to +150°C and withstands a forward surge current of 1 A.

Diode Arrays Feature Summary

• Common anode dual structure enables efficient circuit design for clamping and protection tasks
• Low forward voltage drop ensures minimal power loss during conduction
• High-speed switching capability suitable for RF and microwave applications
• Robust thermal performance with extended operating temperature range

Diode Arrays Applications

• Clamping diodes in RF and microwave circuits
• Protection against electrostatic discharge (ESD) and transient voltages
• Small signal rectification in consumer electronics
• Logic level shifting and demodulation circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'AW' corresponds to the common anode dual configuration rather than single diode variants within the BAT46 series. Confirm that the SOT-323 package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS directives if required for your manufacturing process. Cross-reference the datasheet pinout to avoid orientation errors during assembly.

Diode Arrays Selection Notes

Select this component when a low-capacitance, high-speed solution is needed for signal processing or protection. The common anode arrangement reduces board space compared to discrete single diodes. Consider the 150 mA current limit for load requirements. The SOT-323 package is ideal for space-constrained designs requiring reliable surface-mount integration.

Diode Arrays Part Context

This part belongs to the BAT46 series of small signal Schottky diodes from STMicroelectronics. The series offers various configurations including single and dual diodes in different packages. The BAT46AWFILM specifically denotes the common anode dual version in the SOT-323 tape-and-reel format, distinguishing it from other suffixes like BAT46J or BAT46WFILM which may differ in internal structure or packaging.

Diode Arrays Replacement Considerations

Compatible substitutes include BAT46WT1G and BAT46HT1G from ON Semiconductor, which offer similar electrical characteristics and pinouts. BAT54S from NXP is another alternative but requires verification of the common cathode versus common anode configuration to ensure functional compatibility in existing designs.
