AI Summary	US1G by Taiwan Semiconductor Corporation: Diode 400 V 1A Surface Mount DO-214AC (SMA).	The ES1G-13-F is a superfast recovery diode in an SMA package that serves as an upgraded drop-in replacement. It offers a faster 25 ns reverse recovery time compared to the original's 50 ns, reducing switching losses while maintaining identical 400 V breakdown and 1 A current ratings. Pin-compatible drop-in in SMA package and from the same product family Faster reverse recovery time (25 ns vs 50 ns) for higher efficiency Identical 400 V reverse voltage and 1 A current ratings	The US1G-13-F from Diodes Incorporated is a direct drop-in alternative in the same SMA package. It matches the 400 V reverse voltage rating, 1 A forward current, and 50 ns reverse recovery time of the original part. The only minor trade-off is a slightly higher forward voltage specification of 1.3 V compared to 1.25 V. Pin-compatible drop-in replacement in standard SMA (DO-214AC) package Identical 400 V reverse breakdown voltage and 1 A average current rating Matches 50 ns reverse recovery time Slightly higher maximum forward voltage (1.3 V vs 1.25 V)

You searched one part. Parter watches your whole BOM.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
