Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLL5267B TR is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Zener (Nom): 75 V
• Power - Max: 500 mW
• Tolerance: ±5%
• Package / Case: DO-213AC, MINI-MELF, SOD-80
• Mounting Type: Surface Mount

Secondary Compatibility Parameters:

• Impedance (Max): 270 Ohms (or lower)
• Current - Reverse Leakage @ Vr: 100 nA @ 56 V
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 200 mA (or lower)
• Operating Temperature Range: Must encompass application requirements
• Moisture Sensitivity Level: 1 (Unlimited)

All four substitute parts meet the primary matching criteria. Variations in secondary parameters are noted in the comparison table below.

Engineering Selection Recommendations

For Standard Industrial Applications:

TZM5267B-GS08 and TZM5267B-GS18 are direct functional equivalents to the CLL5267B TR. Both parts are manufactured by Vishay General Semiconductor with active product status, ensuring long-term availability. These parts feature identical Zener voltage, power rating, tolerance, and impedance specifications. The forward voltage is lower (1.1 V vs. 1.25 V), which represents improved performance characteristics. Both are ROHS3 compliant. The primary consideration is maximum operating temperature: these parts are rated to 175°C maximum, compared to the original part's 200°C upper limit. Selection between GS08 and GS18 variants depends on packaging reel configuration requirements; both are electrically identical.

For Automotive and High-Reliability Applications:

TZMC75-GS08 and TZMC75-GS18 are automotive-grade substitutes qualified to AEC-Q101 standard. These parts maintain the 75 V Zener voltage and 500 mW power rating with improved impedance characteristics (250 Ohms vs. 270 Ohms). Operating temperature range is -65°C to 175°C. Forward voltage is specified at 1.5 V @ 200 mA, which is higher than the original part. Both variants are ROHS3 compliant and REACH unaffected. Selection between GS08 and GS18 depends on reel configuration requirements.

Temperature Consideration:

Applications requiring operation above 175°C cannot use any of the listed substitutes. The original CLL5267B TR specification of -65°C to 200°C cannot be fully matched by active alternatives.

Frequently Asked Questions (FAQ)

Q: Can TZM5267B-GS08 directly replace CLL5267B TR in all applications?

A: TZM5267B-GS08 is electrically compatible for applications operating at or below 175°C. The part matches all critical electrical parameters: 75 V Zener voltage, 500 mW power rating, ±5% tolerance, and SOD-80 package. The lower forward voltage (1.1 V vs. 1.25 V) represents improved performance. If your application requires operation above 175°C, this substitute is not suitable.

Q: What is the difference between GS08 and GS18 packaging variants?

A: GS08 and GS18 designations refer to different tape and reel configurations for surface mount assembly. Both TZM5267B-GS08 and TZM5267B-GS18 are electrically identical. Selection depends on your assembly equipment compatibility and reel quantity requirements.

Q: Why should I consider TZMC75-GS08 or TZMC75-GS18 instead of TZM5267B variants?

A: TZMC75 parts are automotive-grade with AEC-Q101 qualification. These are appropriate for automotive, industrial control, and high-reliability applications requiring formal qualification documentation. The impedance is lower (250 Ohms vs. 270 Ohms), which may provide better voltage regulation characteristics in some circuit topologies. Operating temperature range is -65°C to 175°C.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (TZM5267B-GS08, TZM5267B-GS18, TZMC75-GS08, TZMC75-GS18) are ROHS3 compliant and REACH unaffected.

Q: What is the impact of forward voltage differences?

A: The original CLL5267B TR specifies 1.25 V forward voltage @ 200 mA. TZM5267B variants specify 1.1 V, and TZMC75 variants specify 1.5 V. In Zener diode applications, forward voltage primarily affects reverse-biased leakage characteristics and is not typically a limiting factor for substitution. Circuit performance impact is minimal in standard voltage regulation and protection applications.

Q: Can I use these substitutes in circuits designed for -65°C to 200°C operation?

A: No. All substitute parts have a maximum operating temperature of 175°C. If your application requires operation above 175°C, these substitutes are not suitable. You must source alternative parts with higher temperature ratings or redesign the circuit to operate within the 175°C limit.

Q: What inventory considerations should I account for?

A: TZM5267B-GS08 has the highest inventory (25,903 pcs), followed by TZMC75-GS08 (6,423 pcs). TZMC75-GS18 and TZM5267B-GS18 have lower inventory levels (826 and 1,072 pcs respectively). For high-volume production, TZM5267B-GS08 offers the best availability.
