Package and mounting
The GF1G-E3/67A: The GF1G-/67A: The Vishay GF1G-/67A is a standard recovery rectifier diode from the SUPERECTIFIER® series, rated for 400 V reverse voltage and 1 A average forward current. The 2 µs reverse recovery time places it firmly in the standard-recovery class — fine for 50/60 Hz line rectification and bulk DC rail generation, but not a part you spec for a 100 kHz PFC boost stage.
Junction temperature range — design margin for hot environments
Rated for a junction temperature range of -65°C to 175°C, this diode handles the thermal extremes you see in industrial power supplies, motor drive snubbers, and outdoor telecom rectifiers. The 175°C upper limit gives you headroom above the typical 150°C ceiling of commercial parts — useful when the ambient inside a sealed enclosure hits 85°C and the self-heating adds another 50°C.
DO-214BA package — rework and footprint notes
The DO-214BA (GF1) package is a surface-mount outline with a copper tab on the cathode side. The tab is the primary heat path — the board copper area under it sets the thermal resistance. Under a hot-air station, the tab soaks heat fast; preheat the board to 100°C before you try to lift the part, or you risk lifting the pad. Orientation is marked by a cathode band on the body — no ambiguity.
Forward voltage and leakage — the conduction loss picture
Maximum forward voltage is 1.1 V at 1 A forward current. At 1 A DC, that is 1.1 W conduction loss — within the DO-214BA's capability with adequate board copper. Reverse leakage is 5 µA at 400 V rated reverse voltage, which is low enough that it won't drive thermal runaway in a 1 A rectifier application, even at elevated junction temperature.
The GF1G-/67A carries an active lifecycle status. ROHS3 compliant.
