KBP307 matches package and current but is a 600V downgrade from KBP310.
KBP310 is a 1000V, 3A single-phase bridge rectifier in a 4-SIP KBP package. Lower-voltage KBP parts need careful derating review.
KBP307 is only 600V.
Package text matches, pinout not proven.
No firmware interface.
Kept candidate is active.
Direct replacement for KBP310 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Prefer a 1000V or higher 3A KBP bridge with verified pinout.
Using a 600V bridge in place of a 1000V part can fail under line surge or high reverse stress.

| Feature / factor | KBP310 | KBP307 | Alt 2 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 4-SIP, KBP | 4-SIP, KBP | 4-SIP, KBP — same package text | ||
| Pinout | 4 pins | 4 pins | 4 pins — pin functions not shown | ||
| Voltage | 1000 V | 600 V | 600 V — 40% lower VRRM | ||
| Current | 3 A | 3 A | 3 A — same Io | ||
| Temperature | -55 to +150 C | -55 to +150 C | -55 to +150 C — ES attribute match |
Verified drop-in options for KBP310 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
