It delivers 4A peak output current per channel, making it a fit for driving SiC and IGBT power switches in automotive traction inverters, on-board chargers, and battery-management isolation barriers. ## 2500Vrms isolation with 20kV/µs transient immunity Rated for 2500Vrms isolation, the SI8238BB-D-IS1 provides basic insulation for 60V to 600V DC-link systems. The 20kV/µs minimum common-mode transient immunity (CMTI) means the output stays clean when the switching node slews through the isolation barrier — critical in hard-switched inverter stages where the dv/dt at the half-bridge midpoint can exceed 10kV/µs. Propagation delay is 60ns max (tpLH/tpHL) with a 5.6ns max pulse-width distortion, keeping the dead-time error budget tight enough for 100kHz+ PWM switching schemes. The 12ns rise/fall time into a capacitive load means the gate drive edge is fast enough to reduce switching losses in the power stage. Output supply range of 9.4V to 24V covers standard gate-drive rails for both Si MOSFETs (10-12V) and SiC devices (18-20V). The asymmetric high/low drive currents — 2A source, 4A sink — give the gate a stronger pull-down path, which helps prevent Miller turn-on during the switching transition. ## Active production with tape-and-reel ordering option For volume assembly, the tape-and-reel variant SI8238BB-D-IS1R uses the same die and package — identical electrical specs, same 16-SOIC footprint — just a different reel carrier. The tube-packaged SI8238BB-D-IS1 is the standard pick for prototype and low-volume builds.","metaTitle":"Skyworks SI8238BB-D-IS1 Digital Isolator, 2500Vrms, 4A","metaDescription":"Skyworks SI8238BB-D-IS1 dual-channel gate driver isolator, 2500Vrms isolation, 4A peak output, AEC-Q100 automotive grade.
