ISO5851DW Equivalent & Substitute Gate Driver ICs Reference

Part Overview

The Texas Instruments ISO5851DW is a single-channel digital isolator gate driver IC, utilizing capacitive coupling technology, with a voltage isolation rating of 5700Vrms. It delivers 2.7A and 5.5A peak output currents, supports a wide output supply voltage of 15V ~ 30V, and is provided in a 16-SOIC surface mount package. The ISO5851DW is classified with a product status of "Last Time Buy," making it necessary to identify direct substitute models to ensure ongoing design compatibility and component sourcing.

• Common Mode Transient Immunity (Min): 100kV/µs
• Propagation Delay tpLH / tpHL (Max): 110ns, 110ns
• Rise / Fall Time (Typ): 20ns, 20ns
• Current - Output High, Low: 1.5A, 3.4A
• Current - Peak Output: 2.7A, 5.5A
• Voltage - Output Supply: 15V ~ 30V
• Operating Temperature: -40°C ~ 125°C
• Mounting Type: Surface Mount
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Approval Agency: CQC, CSA, UR, VDE
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)
• REACH Status: REACH Unaffected

No additional parameters are used for substitute determination.

Parameter Comparison

Engineering Selection Recommendations

ISO5851DW is designated as "Last Time Buy," while ISO5851DWR is listed as "Active." Both parts carry identical compliance (ROHS3, REACH unaffected), agency approvals (CQC, CSA, UR, VDE), MSL ratings, and package dimensions. Selection may be based on the substitute's "Active" status and availability while maintaining compliance and regulatory equivalence.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine substitute gate driver ICs for ISO5851DW?
A1: Substitutes are chosen based strictly on matching technology, channel count, isolation voltage, output performance, timing characteristics, package type, operating temperature, compliance, and regulatory certifications as detailed in the key parameters table.

Q2: Are ISO5851DW and ISO5851DWR mechanically interchangeable?
A2: Both parts use the same 16-SOIC surface mount package with identical dimensions and mounting type.

Q3: How is functional compatibility ensured between substitutes?
A3: Parameters such as current ratings, propagation delays, rise/fall times, supply voltage range, and regulatory certifications are matched exactly between the main and substitute parts.

Q4: Is regulatory and environmental compliance maintained for the substitute part?
A4: Both parts are ROHS3 Compliant, REACH Unaffected, and approved by CQC, CSA, UR, and VDE. Moisture sensitivity is rated MSL 2 for both.

Q5: What is the distinction between ISO5851DW and ISO5851DWR?
A5: The distinction is limited to packaging type; ISO5851DW is supplied in Tube format, while ISO5851DWR is available in Cut Tape and Digi-Reel® packaging, with all electrical and mechanical parameters being equivalent.
