Applications
SGSP491 is sourced for OEM/EMS electronic assemblies. Typical use depends on the manufacturer datasheet for STMicroelectronics. Confirm electrical ratings, TO-218 mechanics, and AVL notes before design-in or substitution. SJ Chip provides inventory checks and RFQ support for production and shortage fills.
Procurement notes
Confirm the full ordering code, package (TO-218), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.

FAQ
Where to buy SGSP491?
You can request SGSP491 from SJ Chip via the RFQ form on this page or the site-wide RFQ. We confirm manufacturer (STMicroelectronics), package, quantity, and lead time on the quotation.
Is SGSP491 available?
Listed inventory shows 38,695 pcs. Lot, date code, and shippable quantity are confirmed on RFQ — treat the listing as availability to quote, not a guaranteed cart ship.
What is the package of SGSP491?
The sourcing listing shows package TO-218. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.
What are alternatives to SGSP491?
Potential alternatives include STH12N60FI, BUT13P, STH6N100 and other same-series or same-package listings — all require datasheet and pinout checks. These are similar stock for evaluation, not automatic drop-in replacements.
