FAQ
Where to buy 2N3773?
You can request 2N3773 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 2N3773 available?
Listed inventory shows 48,770 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 2N3773?
The sourcing listing shows package TO-3. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.
What are alternatives to 2N3773?
Potential alternatives include MJ11016, TPDV1240, L6472PDTR 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.
