Its 4 A peak output current charges gate capacitance faster than typical 1–2 A isolators, which matters when switching a large IGBT or SiC module where the Miller plateau stretches the turn-on edge. Common-mode transient immunity is rated at 200 kV/µs minimum — that is the slew rate the part can reject before the output glitches. In a motor-drive or inverter where the switching node jumps 600 V in 50 ns, a lower CMTI isolator would couple that edge across the barrier and false-trigger the gate driver. This part stays clean. ## Timing symmetry for dead-time budgets Propagation delay is 75 ns max for both rising and falling edges, with a pulse-width distortion of 8 ns max. That 8 ns spread is the mismatch between the two channels — in a half-bridge configuration, the dead-time must exceed this plus the driver's own turn-off delay to avoid shoot-through. The 10.5 ns rise and 13.3 ns fall times are typical, so the actual dead-time margin lands closer to the 8 ns spec than the raw rise/fall numbers. Output supply range spans 9.6 V to 30 V, covering standard gate-drive rails for Si MOSFETs (12 V), IGBTs (15 V), and SiC devices (18–20 V). The high-side and low-side channels share the same output supply pin, so both gates run from one bias rail. ## Industrial temperature range and safety certifications Safety approvals include CQC, CSA, UR, and VDE — the VDE mark indicates the part meets the reinforced insulation requirements of IEC 60747-17 for basic and reinforced isolation. Product status is Active per the manufacturer.","metaTitle":"Skyworks SI8273DBD-IS1R Digital Isolator, 4A Peak","metaDescription":"Skyworks SI8273DBD-IS1R: 2-channel RF-coupled digital isolator, 2500Vrms isolation, 4A peak output, 200kV/µs CMTI.

Both share the 2-channel RF-coupled architecture, 4 A peak output, 2500 Vrms isolation, and 16-SOIC package. The key difference is common-mode transient immunity: the SI8273DBD-IS1R is rated at 200 kV/µs, while the SI8273DB-IS1R is rated at 150 kV/µs.
