Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI8282CD-ISR is determined by matching the following critical parameters:

• Isolation voltage rating of 5000Vrms
• Single-channel configuration
• Capacitive coupling isolation technology
• Peak output current of 4A with output current specifications of 2.5A (high) and 3A (low)
• Common mode transient immunity of 35kV/µs minimum
• Propagation delay specifications of 50ns maximum for both rising and falling edges
• Pulse width distortion of 5ns maximum
• Operating temperature range of -40°C to 125°C
• 20-SOIC surface mount package with identical mechanical dimensions
• Moisture sensitivity level 3 classification

The SI8282CC-ISR meets all these criteria and qualifies as a direct substitute. The primary distinction is the addition of automotive-grade qualification (AEC-Q100) and enhanced approval agency certifications in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the SI8282CD-ISR and SI8282CC-ISR are active products from Skyworks Solutions Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on application requirements:

The SI8282CD-ISR is suitable for general industrial and commercial applications requiring 5000Vrms isolation with single-channel gate drive capability.

The SI8282CC-ISR provides automotive-grade qualification under AEC-Q100 and is specified for applications requiring automotive-level reliability and compliance. This part carries UL approval in addition to the certifications present on the standard version.

Both parts maintain identical performance characteristics across all timing, current, and isolation parameters. PCB layout and thermal management considerations remain consistent between the two options due to identical package geometry and electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can SI8282CC-ISR be used as a direct replacement for SI8282CD-ISR?

A: Yes. The SI8282CC-ISR is electrically and mechanically identical to the SI8282CD-ISR. All electrical parameters, timing specifications, current ratings, and package dimensions are equivalent. The primary difference is the automotive-grade qualification level of the substitute part.

Q: What is the key difference between these two parts?

A: The SI8282CC-ISR includes AEC-Q100 automotive qualification and UL approval, whereas the SI8282CD-ISR does not carry these certifications. Both parts are manufactured by Skyworks Solutions Inc. using identical capacitive coupling isolation technology and meet the same electrical performance specifications.

Q: Are there any package or pinout differences?

A: No. Both parts use the 20-SOIC package with identical mechanical dimensions (0.295" width, 7.50mm). Pinout and PCB footprint compatibility is guaranteed.

Q: What isolation voltage do these parts provide?

A: Both the SI8282CD-ISR and SI8282CC-ISR provide 5000Vrms isolation rating with a common mode transient immunity of 35kV/µs minimum.

Q: What is the operating temperature range?

A: Both parts operate across -40°C to 125°C, with identical thermal performance characteristics.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the application does not require automotive-grade qualification. If AEC-Q100 compliance is required, the SI8282CC-ISR must be specified. Otherwise, either part meets the same functional and reliability requirements.
