With a continuous drain current of 21 mA at 25 °C and a maximum on-resistance of 500 Ohm at 16 mA gate drive, this is not a power switch — it is a high-voltage, low-current transistor sized for auxiliary supply rails, start-up circuits, and bias feeds in off-line converters and industrial PSUs. ## What the 500 Ohm Rds(on) means for your BOM The 500 Ohm maximum on-resistance at Vgs=10 V and Id=16 mA sets a hard ceiling on useful load current. At 21 mA the voltage drop across the channel is over 10 V — so the part operates as a saturated switch only for loads drawing a few milliamps. The 500 mW power dissipation limit in the SOT-23 package reinforces the same message: this is a signal-level FET, not a driver.","metaTitle":"BSS127H6327XTSA2 SIPMOS N-Ch MOSFET, 600 V, 21 mA, SOT-23","metaDescription":"Infineon BSS127H6327XTSA2 N-channel MOSFET, 600 V Vdss, 21 mA Id, 500 Ohm Rds(on) in SOT-23.

The limiting factor is the high Rds(on) and the 500 mW package dissipation — it can switch at moderate frequencies (tens to low hundreds of kHz) in low-duty-cycle or low-current auxiliary circuits, but it is not designed for high-frequency power conversion."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BSS127H6327XTSA2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BSS127H6327XTSA2 when reusing this data.
