Product details

Three-channel unidirectional isolator with 5.7 kV reinforced isolation

Rated for 100 Mbps, the part keeps up with fast serial buses while staying within the power budget of a 2.25 V to 5.5 V supply rail. The 16-SOIC wide-body package (0.551" body width) provides the creepage distance needed for reinforced insulation in industrial and medical equipment.

100 kV/µs CMTI — why it matters on a motor drive or inverter board

The ISO7830DWWR guarantees a minimum of 100 kV/µs, which is well above the noise from a typical IGBT or SiC MOSFET switching leg. That means the output stays clean — no glitches, no false edges — when the ground on one side jumps several hundred volts in a few nanoseconds. For comparison, the automotive-grade ISO7741QDWRQ1 (4-channel, same 100 Mbps, 5000 Vrms isolation) specifies 40 kV/µs minimum CMTI, so the ISO7830DWWR offers more than double the transient immunity for the same data rate. Propagation delay is symmetrical at 16 ns max for both rising and falling edges, with pulse-width distortion held to 4.1 ns max. That timing consistency matters when the isolator is in a feedback loop or a timing-critical SPI chain — you are not adding skew that forces you to slow the bus down.

Frequently asked questions

What is the equivalent or replacement for ISO7830DWWR?

The ISO7741QDWRQ1 is a 4-channel automotive-grade digital isolator with 5000 Vrms isolation and 40 kV/µs CMTI, but it is not a direct pin-compatible replacement — it has four channels instead of three and a different input/output configuration (3/1 vs 3/0). For a closer functional match, the ISO7830DWR (same die, different tape/reel suffix) is the same part in a different packaging option.

What is the difference between ISO7830DWWR and ISO7830DWR?

The ISO7830DWWR and ISO7830DWR are the same silicon in the same 16-SOIC package. The difference is packaging and handling: the DWWR suffix indicates Tape & Reel (TR) and Cut Tape (CT) options, while the DWR suffix typically indicates a different reel or tube configuration. Electrically they are identical.
