1N6011B-TP Zener Diode Equivalent & Substitute Parts

Part Overview

The 1N6011B-TP is a 30 V Zener diode rated for 500 mW power dissipation in a DO-35 through-hole package. This component is classified as obsolete, necessitating identification of equivalent alternatives for ongoing design support and production requirements. Equivalent parts must maintain identical electrical specifications and mechanical compatibility to ensure direct substitution in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N6011B-TP is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Zener voltage: 30 V nominal
• Power rating: 500 mW maximum
• Tolerance: ±5%
• Impedance (Zzt): 78 Ohms maximum
• Reverse leakage current: 100 nA @ 23 V
• Forward voltage: 1.5 V maximum @ 100 mA

Mechanical & Environmental Requirements:

• Package type: DO-35 axial through-hole configuration
• Operating temperature range: -65°C to 200°C
• Compliance: ROHS3 compliant, REACH unaffected

Parts meeting all specified parameters within these tolerances are classified as direct parametric equivalents. No deviations from stated electrical or mechanical specifications are permitted for substitution classification.

Parameter Comparison

Engineering Selection Recommendations

The 1N6011B-TP is designated as obsolete. The parametric equivalent 1N6011B-TP maintains full electrical and mechanical compatibility with the original specification. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and deployment.

Selection of equivalent parts for the 1N6011B-TP should be based on:

1. Electrical Parameter Match: All zener voltage, power rating, impedance, and leakage specifications must align exactly with the stated values.
2. Package Compatibility: DO-35 axial through-hole configuration is required for mechanical fit in existing PCB designs.
3. Compliance Certification: ROHS3 compliance and REACH unaffected status must be maintained.
4. Temperature Range: Operating temperature capability from -65°C to 200°C must be preserved.

Frequently Asked Questions (FAQ)

Q: Can the 1N6011B-TP be replaced with a different zener voltage rating?

A: No. The 30 V nominal zener voltage is a critical circuit parameter. Substitution with alternative voltage ratings will alter circuit behavior and is not permitted.

Q: What is the significance of the DO-35 package specification?

A: The DO-35 package is an axial through-hole configuration with specific lead diameter, spacing, and mechanical dimensions. This package type is required for compatibility with existing PCB layouts and cannot be substituted with surface-mount or alternative through-hole packages without circuit board redesign.

Q: Are there restrictions on the tolerance specification?

A: The ±5% tolerance specification defines the acceptable range of zener voltage variation. Substitute parts must maintain this tolerance band. Parts with wider or narrower tolerances are not direct equivalents.

Q: Does the 500 mW power rating have substitution flexibility?

A: No. The 500 mW maximum power dissipation rating is a thermal design constraint. Substitution with lower-rated parts risks thermal failure; higher-rated parts may introduce unintended circuit behavior changes and are not considered direct equivalents.

Q: What does the 78 Ohms impedance specification indicate?

A: The impedance (Zzt) value of 78 Ohms maximum defines the dynamic resistance of the zener diode at specified operating conditions. This parameter affects voltage regulation performance and must be matched for functional equivalence.

Q: Is the reverse leakage current specification critical for substitution?

A: Yes. The 100 nA @ 23 V reverse leakage specification defines the off-state behavior of the diode. Deviations from this specification will affect circuit quiescent current and bias conditions.

Q: Can the operating temperature range be extended beyond -65°C to 200°C?

A: No. The specified operating temperature range defines the thermal limits for reliable operation. Substitute parts must maintain this range. Operation outside these limits is not supported.

Q: What is the impact of ROHS3 compliance on part selection?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. For applications requiring regulatory compliance, substitute parts must maintain ROHS3 certification status.
