Key Parameters

Substitute Part Grouping Explanation

Substitution of the TZX11C-TAP is permissible when the alternative component meets the following criteria:

Electrical Parameters (Critical for Substitution):

• Zener voltage nominal rating of 11 V
• Maximum power dissipation of 500 mW
• Through-hole mounting configuration
• DO-35 package compatibility

Regulatory & Compliance Parameters:

• ROHS3 compliance status
• Active product status
• REACH unaffected classification

Environmental Parameters:

• Operating temperature range that encompasses or exceeds -65°C to 175°C

The substitute parts listed below satisfy these substitution criteria across all critical electrical and mechanical parameters while maintaining regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain electrical equivalence at the 11 V, 500 mW specification and are mechanically compatible with DO-35 through-hole applications. Selection among substitutes is determined by the following factors:

1N5241B TR PBFREE (Central Semiconductor Corp)

• Active product status with ROHS3 compliance
• Extended operating temperature range to 200°C
• Lower forward voltage (1.1 V @ 200 mA) compared to primary part
• Suitable for applications requiring enhanced thermal performance

BZX79C11 (Taiwan Semiconductor Corporation)

• Active product status with ROHS3 compliance
• Operating temperature range matches primary part (-65°C ~ 175°C)
• Lower impedance (20 Ohms) and reverse leakage (100 nA @ 8 V)
• Tape & Reel packaging configuration

BZX79C11-T50A (onsemi)

• Active product status with ROHS3 compliance
• Extended operating temperature range to 200°C
• Lower impedance (20 Ohms) and reverse leakage (100 nA @ 8 V)
• Cut Tape packaging configuration
• Highest inventory availability among substitutes

All substitute parts satisfy regulatory compliance requirements and maintain functional equivalence for direct substitution in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 1N5241B TR PBFREE be used as a direct replacement for the TZX11C-TAP?

A: Yes. Both components share identical nominal Zener voltage (11 V) and maximum power rating (500 mW) with compatible DO-35 through-hole packaging. The 1N5241B TR PBFREE provides an extended operating temperature range (-65°C ~ 200°C) and lower forward voltage characteristics, making it functionally equivalent for circuit substitution.

Q: What is the difference between BZX79C11 and BZX79C11-T50A?

A: Both parts are manufactured by different suppliers (Taiwan Semiconductor Corporation and onsemi respectively) with identical electrical specifications: 11 V nominal Zener voltage, 500 mW power rating, 20 Ohms maximum impedance, and 100 nA reverse leakage. The primary difference is packaging format: BZX79C11 is supplied in Tape & Reel configuration, while BZX79C11-T50A is supplied in Cut Tape configuration. Both are mechanically and electrically interchangeable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (1N5241B TR PBFREE, BZX79C11, and BZX79C11-T50A) maintain ROHS3 compliance status and REACH unaffected classification, matching the regulatory compliance of the primary TZX11C-TAP component.

Q: Does the impedance difference between parts affect circuit performance?

A: The TZX11C-TAP specifies 25 Ohms maximum impedance, while substitute parts specify 20 Ohms (BZX79C11, BZX79C11-T50A) or 22 Ohms (1N5241B TR PBFREE). Lower impedance values represent improved performance characteristics and do not create compatibility issues in standard Zener diode applications. Circuit designs based on the primary part specifications remain valid with substitute parts.

Q: What is the significance of the ±5% tolerance specification on substitute parts?

A: The substitute parts specify ±5% Zener voltage tolerance, while the primary TZX11C-TAP does not list a tolerance specification. The ±5% tolerance on substitutes defines the acceptable variation range around the 11 V nominal value (10.45 V to 11.55 V). This specification is standard for Zener diodes and does not affect substitution compatibility in applications where the primary part tolerance was not explicitly constrained.

Q: Can these parts be used in automotive applications?

A: The primary TZX11C-TAP carries AEC-Q101 automotive qualification. While the substitute parts do not list explicit automotive qualification in the provided specifications, all parts maintain ROHS3 compliance and active product status. Application suitability for automotive environments requires evaluation against specific automotive qualification requirements of the end application.
