AC DC Converters, Offline Switchers Procurement Notes

Verify the manufacturer designation as Microsemi Corporation or its successor entities, noting that Semtech acquired Microsemi's semiconductor assets. Confirm the specific suffix 'G-LF-T' corresponds to lead-free compliance and tape-and-reel packaging. Ensure the datasheet references align with the SOD-323 package dimensions and electrical characteristics provided in official documentation before finalizing procurement specifications.

AC DC Converters, Offline Switchers Selection Notes

Select this component when bidirectional protection is required for 15 V systems with limited board space. The SOD-323 package offers a compact footprint compared to larger TVS arrays. Consider the 75 pF capacitance limit for signal integrity requirements; if lower capacitance is needed, evaluate alternative series. Verify that the 350 W peak pulse rating meets the expected surge environment of the target application circuit.

AC DC Converters, Offline Switchers Part Context

This part belongs to the IPS15C series of TVS diodes, which are engineered for general-purpose ESD and transient protection. The series utilizes silicon avalanche technology to clamp voltage spikes rapidly. The 'SO' designation typically indicates the small outline package style, while 'LF' denotes lead-free material composition compliant with environmental directives. This family is widely used in industrial and commercial electronics requiring reliable overvoltage protection.

AC DC Converters, Offline Switchers Replacement Considerations

Cross-reference with other 15 V bidirectional TVS diodes in the SOD-323 package. Verify that substitute parts match the 16.7 V breakdown voltage and 29 V clamping voltage limits. Ensure equivalent peak pulse current and capacitance ratings to maintain circuit performance and reliability standards.
