BAS70-04-HF

Diode Arrays Overview

The BAS70-04-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SOT-323 (SC-70) surface-mount package. The device is constructed using silicon and offers a maximum repetitive peak reverse voltage of 40 V with a continuous forward current rating of 70 mA. Key electrical parameters include a maximum DC reverse leakage current of 1 µA at rated voltage, a typical forward voltage drop of 0.5 V at 10 mA, and a maximum junction capacitance of 2 pF. It operates within a temperature range of -55 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific manufacturer source when sourcing this component, as the BAS70 designation is widely used by multiple semiconductor vendors including Infineon and Nexperia. Confirm that the datasheet explicitly lists Comchip Technology as the manufacturer to ensure compliance with the specified RoHS and Halogen-free requirements associated with the -HF suffix. Cross-reference the package marking codes to distinguish between different manufacturers offering identical part numbers.

Diode Arrays Selection Notes

Select this component for designs requiring low forward voltage and high switching speeds in compact form factors. Ensure the circuit's reverse voltage does not exceed 40 V and the average forward current remains below 70 mA. Consider the thermal dissipation capabilities of the SOT-323 package if operating near maximum ratings. Verify compatibility with automated pick-and-place equipment due to the small outline dimensions.

Diode Arrays Part Context

This component belongs to the family of small-signal Schottky diodes designed for general-purpose rectification and signal processing. It serves as a low-power alternative to standard PN junction diodes where speed and efficiency are prioritized over high current handling. The -HF suffix indicates compliance with hazardous substance restrictions, aligning with modern environmental standards for electronic manufacturing.
