What this Schottky diode is and where it fits
The Infineon BAT1502ELE6327XTMA1 is a small-signal Schottky diode rated for 4 V reverse voltage and 110 mA average rectified current. It is built for low-voltage rectification, clamping, and fast-switching tasks where forward drop matters — the 410 mV maximum at 10 mA keeps losses down in battery rails or low-voltage DC buses. The 350 pF capacitance at 0 V and 1 MHz suits it for RF detector or high-speed switching applications where junction charge recovery is not a concern (Schottky has none). Junction temperature range of -55°C to 150°C covers automotive under-hood and industrial environments without derating anxiety.
Package and mounting — what to expect on the reel
This diode comes in a PG-TSLP-2-19 package, which is Infineon's leadless plastic package with two terminals, sized as a 0402 (1006 Metric) footprint. It is surface-mount only — no through-hole option. The reverse leakage is 5 µA at 1 V, which is typical for a small Schottky at this voltage class; watch it in high-temperature operation because leakage doubles with temperature.
Lifecycle and compliance — active, ROHS3, no phase-out risk
It is ROHS3 compliant, so no exemption issues for EU or similar markets.
