Mounting Type: Through Hole
Operating Temperature Range: Must encompass or exceed -55°C to 175°C

Acceptable Variation Parameters:

Voltage - Forward (Vf): Substitutes may vary within component technology specifications
Reverse Recovery Time (trr): Substitutes with equal or faster recovery characteristics are acceptable

Engineering Selection Recommendations

BYV26A-TAP (Parametric Equivalent)

The BYV26A-TAP is a direct parametric equivalent to the BYV26A-TR. Both components are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications: 200 V reverse voltage, 1 A average rectified current, 2.5 V forward voltage at 1 A, 30 ns reverse recovery time, and -55°C to 175°C operating temperature range. The primary difference is packaging format: BYV26A-TAP is supplied in Cut Tape format rather than Tape & Reel. Both maintain ROHS3 compliance and Active product status. Selection of BYV26A-TAP is appropriate when Cut Tape packaging is compatible with assembly processes.

1N3611 (Manufacturer Recommended Alternative)

The 1N3611, manufactured by Microchip Technology, meets the core voltage and current requirements (200 V, 1 A) and operates across an extended temperature range (-65°C to 175°C). This component uses Standard technology rather than Avalanche technology and exhibits lower forward voltage (1.1 V @ 1 A) and lower reverse leakage (1 µA @ 200 V). The 1N3611 is supplied in bulk packaging with A-series axial package format. This substitute is classified as RoHS non-compliant, which may restrict use in applications requiring RoHS compliance. Selection of 1N3611 is appropriate for applications where RoHS compliance is not mandated and where lower forward voltage characteristics are beneficial.

EGP10D (Manufacturer Recommended Alternative)

The EGP10D, manufactured by Fairchild Semiconductor, meets the core voltage and current requirements (200 V, 1 A) and maintains fast recovery characteristics (≤ 500ns, 50 ns reverse recovery time). This component uses Standard technology and exhibits lower forward voltage (950 mV @ 1 A) compared to the BYV26A-TR. The EGP10D operates across -65°C to 150°C, which provides lower maximum junction temperature than the BYV26A-TR. The component is supplied in bulk packaging with DO-204AL (DO-41) axial package format. Selection of EGP10D is appropriate for applications where the reduced maximum operating temperature is acceptable and where DO-41 package compatibility exists.

Frequently Asked Questions (FAQ)

Q: Can BYV26A-TAP be used as a direct replacement for BYV26A-TR?

A: Yes. BYV26A-TAP is a parametric equivalent with identical electrical specifications and compliance status. The only difference is packaging format (Cut Tape versus Tape & Reel). Mechanical fit and assembly process compatibility must be verified for your specific application.

Q: What is the primary difference between the BYV26A-TR and 1N3611?

A: The BYV26A-TR uses Avalanche technology with 2.5 V forward voltage, while the 1N3611 uses Standard technology with 1.1 V forward voltage. Both meet 200 V and 1 A specifications. The 1N3611 is RoHS non-compliant, which may restrict use in regulated applications.

Q: Is EGP10D suitable for applications requiring -55°C operation?

A: No. The EGP10D operates from -65°C to 150°C, which does not meet the -55°C to 175°C range of the BYV26A-TR. The maximum junction temperature of 150°C is lower than the BYV26A-TR specification of 175°C.

Q: What packaging considerations apply when selecting a substitute?

A: The BYV26A-TR uses SOD-57 axial package. Substitutes use alternative axial packages: BYV26A-TAP uses SOD-57, 1N3611 uses A-series axial, and EGP10D uses DO-204AL (DO-41). Physical dimensions and lead spacing must be verified for PCB compatibility and assembly equipment compatibility.

Q: Are all substitutes RoHS compliant?

A: No. BYV26A-TR and BYV26A-TAP are ROHS3 Compliant. The 1N3611 is RoHS non-compliant. RoHS compliance status for EGP10D was not provided in the specification data. Compliance verification is required for regulated applications.

Q: What is the significance of reverse recovery time differences?

A: The BYV26A-TR and BYV26A-TAP specify 30 ns reverse recovery time (fast recovery). The EGP10D specifies 50 ns. The 1N3611 uses Standard recovery (>500ns). Faster recovery times reduce switching losses in high-frequency applications. Selection depends on circuit operating frequency requirements.

Q: Can 1N3611 be used in applications requiring ROHS compliance?

A: No. The 1N3611 is classified as RoHS non-compliant. Applications subject to RoHS regulations must use BYV26A-TR, BYV26A-TAP, or verify EGP10D compliance status with the manufacturer.
