Key Parameters

Substitute Part Grouping Explanation

The SI8285CC-ISR qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

• Manufacturer: Skyworks Solutions Inc.
• Technology: Capacitive Coupling
• Number of Channels: 1
• Common Mode Transient Immunity: 125kV/µs
• Propagation Delay: 50ns / 50ns
• Pulse Width Distortion: 5ns
• Rise / Fall Time: 5.5ns / 8.5ns
• Current - Output High, Low: 2A / 4.1A
• Current - Peak Output: 4A
• Voltage - Output Supply: 13.2V ~ 30V
• Operating Temperature: -40°C ~ 125°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Base Product Number: SI8285
• Moisture Sensitivity Level: 3 (168 Hours)

Differing Parameter:

• Voltage - Isolation: 3750Vrms (versus 5000Vrms in SI8285CD-ISR)

The SI8285CC-ISR operates at a reduced isolation voltage specification. Substitution is valid only when application requirements permit operation at 3750Vrms isolation voltage.

Parameter Comparison

Engineering Selection Recommendations

Both SI8285CD-ISR and SI8285CC-ISR maintain active product status from Skyworks Solutions Inc. and carry equivalent regulatory certifications (CQC, CSA, VDE). The SI8285CC-ISR is suitable for applications where the isolation voltage requirement is 3750Vrms or lower. When isolation voltage specifications exceed 3750Vrms, the SI8285CD-ISR with 5000Vrms isolation is required. Both devices share identical electrical performance characteristics for propagation delay, output current, timing parameters, and thermal operating range, ensuring functional equivalence within their respective isolation voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can SI8285CC-ISR replace SI8285CD-ISR in all applications?

A: No. The SI8285CC-ISR operates at 3750Vrms isolation voltage, compared to 5000Vrms for the SI8285CD-ISR. Substitution is valid only when application isolation voltage requirements are 3750Vrms or lower.

Q: Are the gate driving characteristics identical between these parts?

A: Yes. Both devices share identical propagation delay (50ns / 50ns), pulse width distortion (5ns), output current ratings (4A peak), and common mode transient immunity (125kV/µs).

Q: Do both parts use the same package?

A: Yes. Both SI8285CD-ISR and SI8285CC-ISR use 16-SOIC surface mount packaging with 0.295" (7.50mm) width, ensuring PCB layout compatibility.

Q: What are the regulatory certifications for each part?

A: SI8285CD-ISR carries CQC, CSA, UR, and VDE certifications. SI8285CC-ISR carries CQC, CSA, UL, and VDE certifications. Both meet international safety standards.

Q: Are there moisture sensitivity differences?

A: No. Both parts have identical Moisture Sensitivity Level (MSL) rating of 3 (168 Hours), requiring equivalent handling and storage protocols.
