1N5265C-TAP Equivalent & Substitute Parts

Part Overview

The 1N5265C-TAP is a through-hole zener diode rated at 62 V nominal with 500 mW power dissipation capability. Manufactured by Vishay General Semiconductor - Diodes Division, this component is packaged in DO-204AH (DO-35) axial configuration and maintains Active product status. The device is qualified to AEC-Q101 automotive standards and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance is required across different packaging formats, tolerance specifications, or when primary inventory availability is constrained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5265C-TAP is determined by the following critical parameters: nominal zener voltage (62 V), through-hole mounting configuration, and automotive-grade qualification. Substitute parts must maintain the 62 V nominal zener voltage specification to ensure circuit voltage regulation performance. All identified substitutes operate within the -65°C to 175°C temperature range and support through-hole assembly methods.

The 1N5265BDO35 provides electrical equivalence with identical zener voltage and power rating, differing only in tolerance specification (±5% versus ±2%) and forward voltage characteristics. This part is suitable for applications where tighter tolerance control is not required.

The 2EZ62D5/TR8 offers higher power dissipation capability (2 W versus 500 mW) in a larger DO-204AL (DO-41) package format. This substitute is applicable in designs requiring increased thermal headroom or higher current handling capacity at the same 62 V regulation point.

Parameter Comparison

Engineering Selection Recommendations

1N5265BDO35 Selection Criteria: This substitute is appropriate for applications where the ±2% tolerance requirement of the primary part can be relaxed to ±5%. Both parts maintain ROHS3 compliance and Active product status. The 1N5265BDO35 operates across the full -65°C to 175°C temperature range and provides equivalent reverse leakage characteristics. Forward voltage increases from 1.1 V to 1.5 V at 200 mA, which may impact circuit efficiency in forward-biased applications. Packaging remains compatible with standard through-hole assembly processes.

2EZ62D5/TR8 Selection Criteria: This substitute is applicable when circuit design requires power dissipation exceeding 500 mW at the 62 V regulation point. The larger DO-204AL (DO-41) package accommodates the 2 W power rating and provides lower impedance (60 Ohms versus 185 Ohms), resulting in improved voltage regulation stability. The operating temperature range is limited to -65°C to 150°C, which is acceptable for most industrial and automotive applications. Critical consideration: this part is RoHS non-compliant, restricting use in applications subject to RoHS3 regulatory requirements. Reverse leakage increases to 500 nA at 47.1 V, which may be significant in high-impedance circuit topologies.

Frequently Asked Questions (FAQ)

Q: Can the 1N5265BDO35 be used as a direct replacement for the 1N5265C-TAP?

A: The 1N5265BDO35 provides functional equivalence for 62 V zener regulation with identical power rating and temperature range. The primary difference is tolerance specification: ±5% versus ±2%. Direct substitution is valid when circuit design tolerates the wider voltage tolerance band. Both parts are ROHS3 compliant and maintain Active product status.

Q: What are the physical differences between the 1N5265C-TAP and 2EZ62D5/TR8?

A: The 1N5265C-TAP uses the DO-204AH (DO-35) package, a smaller axial configuration. The 2EZ62D5/TR8 uses the DO-204AL (DO-41) package, which is physically larger to accommodate the 2 W power rating. Both are through-hole components with axial lead configuration, but PCB layout and thermal management considerations differ due to package size.

Q: When should the 2EZ62D5/TR8 be selected over the 1N5265C-TAP?

A: The 2EZ62D5/TR8 is selected when circuit power dissipation requirements exceed 500 mW at the 62 V regulation point. The 2 W rating provides thermal margin for high-current applications. Lower impedance (60 Ohms) improves voltage regulation performance under load transients. However, RoHS non-compliance restricts use in regulated markets requiring ROHS3 certification.

Q: Are there temperature range limitations when substituting parts?

A: The 1N5265C-TAP and 1N5265BDO35 both operate across -65°C to 175°C. The 2EZ62D5/TR8 is limited to -65°C to 150°C. For applications requiring operation above 150°C, the 2EZ62D5/TR8 is not suitable. The primary and 1N5265BDO35 substitute maintain full temperature range equivalence.

Q: How do tolerance differences affect circuit performance?

A: The 1N5265C-TAP specifies ±2% tolerance, constraining zener voltage to 60.76 V to 63.24 V. The 1N5265BDO35 specifies ±5% tolerance, allowing 58.9 V to 65.1 V. In voltage regulation circuits, wider tolerance may result in greater output voltage variation across production lots. Critical applications requiring tight voltage control should retain the ±2% specification.

Q: What is the significance of impedance differences between substitutes?

A: Impedance affects voltage regulation stability under load changes. The 1N5265C-TAP and 1N5265BDO35 both specify 185 Ohms maximum impedance. The 2EZ62D5/TR8 specifies 60 Ohms, providing superior regulation performance with lower voltage ripple under dynamic load conditions. Lower impedance is advantageous in noise-sensitive applications.

Q: Can the 2EZ62D5/TR8 be used in automotive applications?

A: The 2EZ62D5/TR8 is not AEC-Q101 qualified and is RoHS non-compliant. The 1N5265C-TAP carries AEC-Q101 automotive qualification and ROHS3 compliance. For automotive applications subject to AEC-Q101 requirements, the 2EZ62D5/TR8 is not suitable. The 1N5265BDO35 maintains ROHS3 compliance but lacks explicit AEC-Q101 qualification in the provided specifications.
