The 1100 V blocking rating gives headroom on a 400 VDC bus or a 480 VAC rectified rail — the diode stays out of avalanche during line transients that would punch through a 1000 V part. ## Junction temperature and leakage at the high-voltage end Reverse leakage is specified at 4 µA at 1100 V — a tight figure for a 1.4 A part at this voltage class, meaning the die's passivation and edge termination hold well under bias. Junction capacitance is 40 pF at 10 V and 1 MHz — low enough that the diode does not add significant switching loss in a 100 kHz boost converter; the 60 ns trr dominates the turn-off energy. ## Through-hole axial package, tape-and-reel for automated insertion The A-axial through-hole package suits point-to-point wiring, terminal boards, and high-reliability assemblies where a surface-mount diode would be mechanically stressed. Supplied in tape and reel (TR suffix), the 1N6631/TR feeds into axial-lead forming and insertion machines — a single reel change keeps the line running without manual kitting.","metaTitle":"Microchip 1N6631/TR Fast Recovery Diode, 1100V, 1.4A, Axial","metaDescription":"Microchip Technology 1N6631/TR standard fast recovery diode, 1100V Vrrm, 1.4A Io, 60ns trr, -65 to 150°C junction.
