Key Parameters

Substitute Part Grouping Explanation

Substitute parts for TSF20U45C are grouped exclusively by matching essential electrical characteristics and mechanical form factors. All compared devices are Schottky diode arrays with a 1 Pair Common Cathode configuration, 45 V maximum DC reverse voltage, and a TO-220-3 Full Pack, Isolated Tab (ITO-220AB) package. Substitution logic prioritizes current rating per diode, forward voltage, reverse leakage, and compliance certifications. Only parts with identical configuration, compatible electrical ratings, and equivalent package are considered substitutes.

Key parameters for substitute selection:

• Diode configuration (1 Pair Common Cathode)
• Technology (Schottky)
• Maximum reverse voltage (45 V)
• Average rectified current rating (per diode)
• Forward voltage at rated current
• Reverse leakage at rated voltage
• Package type and mounting
• RoHS and REACH compliance status
• Moisture Sensitivity Level (MSL)
• Active product status

Parameter Comparison

Engineering Selection Recommendations

All substitute models, including STF2045C, MBRF1545CT-E3/45, and MBRF2545CT-E3/45, are active products and RoHS3 compliant. TSF20U45C, MBRF1545CT-E3/45, and MBRF2545CT-E3/45 are REACH unaffected; STF2045C is REACH affected. Moisture Sensitivity Level is listed as 1 (Unlimited) across all parts. All devices are in through-hole TO-220-3 Full Pack, Isolated Tab packages and support the same primary electrical design requirements within the data presented.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting TSF20U45C with alternative models?
A1: Substitution is based on matching diode configuration, technology, maximum reverse voltage, average rectified current per diode, forward voltage at rated current, reverse leakage at rated voltage, package, mounting type, RoHS/REACH compliance, moisture sensitivity level, and product status.

Q2: Are all substitute parts mechanically compatible with designs for TSF20U45C?
A2: Yes, all listed substitutes use the TO-220-3 Full Pack, Isolated Tab (ITO-220AB) through-hole package.

Q3: How should RoHS and REACH compliance influence substitute selection?
A3: Direct substitution should consider only models with equal or better compliance status as indicated for RoHS and REACH. All substitutes are RoHS3 compliant; only STF2045C is REACH affected.

Q4: What differences exist in the electrical parameters among these substitutes?
A4: Differences include average rectified current, forward voltage at rated current, and reverse leakage current. Selection should strictly follow the values provided to ensure compatibility.

Q5: Is product status consistent among all substitute part numbers?
A5: Yes, all substitute part numbers, including the TSF20U45C, are listed as active.
