CLL3595 TR Equivalent & Substitute Parts

Part Overview

The CLL3595 TR is a general-purpose rectifier diode manufactured by Central Semiconductor Corp, rated for 150V DC reverse voltage and 150mA average rectified current in a surface mount SOD-80 package. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The obsolete status necessitates evaluation of functionally equivalent alternatives to maintain supply chain reliability and design compatibility.

Substitute Part Grouping Explanation

Substitution of the CLL3595 TR is determined by electrical parameter equivalence across the following critical specifications:

Electrical Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 150 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 200 mA
• Reverse Recovery Time (trr): 3 µs
• Current - Reverse Leakage @ Vr: 1 nA @ 125 V
• Capacitance @ Vr, F: 8 pF @ 0V, 1MHz
• Technology: Standard
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Mechanical Compatibility:

• Mounting Type: Surface Mount
• Package compatibility within SOD series variants

The CMHD3595 TR PBFREE meets all electrical parameter requirements and maintains functional equivalence. Package differences (SOD-80 versus SOD-123) represent physical form factor variations within the same diode classification and require PCB layout verification.

Engineering Selection Recommendations

The CMHD3595 TR PBFREE is the manufacturer-recommended substitute for the obsolete CLL3595 TR. Selection of this alternative is based on the following engineering factors:

Product Status Consideration: The CLL3595 TR is classified as obsolete. The CMHD3595 TR PBFREE maintains active product status with current manufacturing and inventory support (18,427 pcs in stock versus 1,114 pcs for the obsolete part).

Electrical Equivalence: All critical electrical parameters are identical between the two parts: reverse voltage rating, forward current capacity, forward voltage drop, reverse recovery time, reverse leakage current, and junction capacitance. These specifications ensure functional interchangeability in circuit operation.

Compliance and Certifications: The CMHD3595 TR PBFREE is ROHS3 compliant and REACH unaffected, providing improved regulatory alignment compared to the obsolete CLL3595 TR. Both parts carry EAR99 export classification and identical HTSUS codes.

Physical Form Factor: The substitute uses SOD-123 packaging instead of SOD-80. Both are surface mount packages within the SOD (Small Outline Diode) family. PCB layout modification is required to accommodate the different package footprint.

Temperature Operating Range: The CMHD3595 TR PBFREE operates from -65°C to 150°C, compared to -65°C to 200°C for the original part. This represents a 50°C reduction in maximum junction temperature. Applications requiring operation above 150°C require alternative evaluation.

Frequently Asked Questions (FAQ)

Q: Can the CMHD3595 TR PBFREE directly replace the CLL3595 TR without circuit modification?

A: Electrical substitution is direct. All voltage, current, and switching characteristics are identical. Physical PCB layout modification is required due to package form factor change from SOD-80 to SOD-123.

Q: What is the difference between SOD-80 and SOD-123 packages?

A: Both are surface mount small outline diode packages. SOD-123 is a smaller form factor than SOD-80. The packages have different footprints, lead spacing, and land pattern requirements on the PCB. Mechanical compatibility must be verified against available PCB space and design constraints.

Q: Are there any electrical performance differences between CLL3595 TR and CMHD3595 TR PBFREE?

A: No electrical performance differences exist for the specified parameters. Both parts have identical reverse voltage (150V), forward current (150mA), forward voltage drop (1V @ 200mA), reverse recovery time (3µs), reverse leakage (1nA @ 125V), and junction capacitance (8pF @ 0V, 1MHz).

Q: Why is the maximum junction temperature lower for the CMHD3595 TR PBFREE?

A: The CMHD3595 TR PBFREE specifies -65°C to 150°C operating range versus -65°C to 200°C for the CLL3595 TR. This is a manufacturer specification difference. Applications requiring sustained operation above 150°C must evaluate alternative parts.

Q: What does PBFREE designation mean?

A: PBFREE indicates lead-free construction, compliant with RoHS3 regulations. This eliminates lead from solder and component materials.

Q: Is the CMHD3595 TR PBFREE in active production?

A: Yes. The part is classified as active product status with 18,427 pcs currently in stock, ensuring supply chain availability and ongoing manufacturing support.

Q: What certifications apply to the CMHD3595 TR PBFREE?

A: The part is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification.
