BAT46ZFILM

Single Diodes Overview

The BAT46ZFILM is a small signal Schottky diode manufactured by STMicroelectronics, designed for high-voltage applications. It features a single diode configuration housed in an SOD-123 surface-mount package. The device supports a maximum repetitive reverse voltage (Vrrm) of 100 V and a forward current (If) of 150 mA. Key electrical parameters include a maximum forward voltage of 0.45 V at rated current, a reverse leakage current of 5 µA, and a junction capacitance of 6 pF. It operates within a temperature range of -65°C to +150°C and withstands a forward surge current of 1 A.

Single Diodes Feature Summary

• Utilizes silicon Schottky barrier technology for low forward voltage drop and fast switching speeds.
• Engineered for efficient signal routing and protection in high-voltage circuits.
• Constructed with a robust single-diode structure suitable for compact surface-mount designs.

Single Diodes Applications

• High-voltage protection circuits
• Signal routing and clamping
• Low-loss rectification in consumer electronics

Single Diodes Procurement Notes

Verify the specific suffix 'Z' against official STMicroelectronics documentation to confirm the exact packaging type and tape-and-reel specifications. Ensure compatibility with SOD-123 footprint requirements during PCB layout. Cross-reference datasheet revisions to confirm thermal and electrical ratings match design constraints before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a single Schottky diode with 100 V blocking capability and 150 mA continuous current rating is required in a compact SOD-123 package. Consider its low junction capacitance for high-frequency signal applications. Evaluate thermal management needs given the 150°C maximum junction temperature limit and ensure the application does not exceed the specified surge current limits.

Single Diodes Part Context

This part belongs to the BAT46 series of small signal Schottky diodes from STMicroelectronics. The series is characterized by low forward voltage and high-speed switching capabilities. The BAT46ZFILM variant specifically denotes the SOD-123 surface-mount package configuration, distinguishing it from other package options like SOD-323 or through-hole variants within the same electrical family.

Single Diodes Replacement Considerations

Check for direct substitutes such as BAT46JFILM if SOD-323 packaging is acceptable, noting the package difference. Verify equivalent electrical ratings for any generic Schottky diodes considered as alternatives, ensuring Vrrm and If specifications meet or exceed the original requirements.
