The 57 nC gate charge at 4.5 V is moderate for a 20 A P-channel in a TO-252 package. It means the gate driver needs to source about 57 nC per switching cycle; at 100 kHz switching frequency the average gate-drive current is roughly 5.7 mA, well within the capability of a typical MOSFET driver IC. ## 20 V Vdss — confirm the rail voltage plus transients The 20 V drain-source rating sets a hard ceiling. This part is sized for 5 V, 9 V, or 12 V rails where the maximum transient does not exceed 20 V. It is not a candidate for 24 V or 48 V bus switches — the margin is insufficient. The input capacitance of 4400 pF at 10 V Vds is typical for a 20 A P-channel; it does not impose unusual drive demands at moderate switching frequencies. ## TO-252 package — thermal and footprint notes The TO-252-3 (DPak) surface-mount package with a single exposed tab requires a copper island on the PCB for thermal dissipation. The datasheet specifies 1 W maximum dissipation at ambient (Ta) and 36 W at the case (Tc). ## Active production — no end-of-life flags The 2SJ687-ZK--AY carries an active product status. The part is ROHS3 compliant.","metaTitle":"2SJ687-ZK-E1-AY P-Channel MOSFET, 20V 20A, 7mOhm Rds(on)","metaDescription":"2SJ687-ZK-E1-AY P-Channel MOSFET from Renesas, 20V Vdss, 20A Id, 7mOhm Rds(on) at 4.5V gate drive.

At switching frequencies up to 100 kHz the gate-drive current requirement is about 5.7 mA average, which a standard MOSFET driver can supply. Above 200 kHz the switching losses from the gate charge and output capacitance (Coss, not listed) will dominate the dissipation budget, so the part is best suited for load-switching, OR-ing, and low-to-medium frequency DC-DC converters rather than high-frequency resonant converters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/2SJ687-ZK-E1-AY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/2SJ687-ZK-E1-AY when reusing this data.
