Frequently Asked Questions

Which design checks make SMCJ188A-E3/57T suitable for tvs diode (uni-directional) sourcing?

SMCJ188A-E3/57T should be reviewed against the approved BOM because it provides 2 pins in a tvs diode (uni-directional) context for power rectifiers and related production designs.

For PCB and assembly planning, how should buyers treat the package on SMCJ188A-E3/57T?

Buyers should confirm the Diodes Moulded footprint and the listed 2 pins before substituting this part, because package mismatch can block assembly even when electrical ratings look similar.

When comparing alternate suppliers, which documented rating is most important to preserve?

Keep the -55 to 150 °C rating aligned with the original design requirement, then verify manufacturer, lifecycle, and datasheet traceability before approving an alternate RFQ line.
