The 500 Ohm maximum on-resistance at 16 mA gate drive of 10 V is the trade-off for that breakdown voltage in a tiny footprint — conduction loss is higher than a larger package, but the board area saved often wins in space-constrained PSU or industrial control designs. Gate charge is 0.65 nC at 10 V, which keeps switching losses negligible at low frequencies — the input capacitance of 21 pF at 25 V drain-source means the gate driver sees a light capacitive load, so a simple resistor drive from a GPIO or a small-signal BJT is sufficient. The threshold voltage maximum is 2.6 V at 8 µA drain current — this is a logic-level-compatible turn-on, but the drive voltage range of 4.5 V to 10 V for rated Rds(on) means a 3.3 V gate drive will not achieve the specified on-resistance; plan for at least 4.5 V gate drive if conduction loss matters.","metaTitle":"Infineon BSS127IXTSA1 N-Channel MOSFET, 600 V, 21 mA","metaDescription":"Infineon BSS127IXTSA1 small-signal N-Channel MOSFET, 600 V drain-source, 21 mA continuous drain, 500 Ohm Rds(on), SOT-23-3.
