BYX83TAP Equivalent & Substitute Parts

Part Overview

The BYX83TAP is an avalanche diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 400 V DC reverse voltage and 2 A average rectified current in a through-hole SOD-57 axial package. This component is classified as Active and is ROHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, packaging formats, or inventory availability while maintaining electrical and mechanical compatibility within specified parameters.

Substitute Part Grouping Explanation

Substitute parts for the BYX83TAP are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters (Critical):

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 2 A
Mounting Type: Through Hole
Package compatibility: SOD-57 axial or equivalent through-hole axial packages

Compliance Parameters:

RoHS Status: ROHS3 Compliant
Product Status: Active

The BYX83TAP has two identified substitutes: BYW53-TAP (parametric equivalent) and EGP20G (manufacturer recommended). Both meet the core voltage and current requirements. The BYW53-TAP maintains identical electrical specifications and technology classification (Avalanche) with packaging variation (Cut Tape versus Tape & Box). The EGP20G is a general-purpose diode with different technology (Standard versus Avalanche) and package format (DO-15 versus SOD-57) but satisfies the same voltage and current ratings.

Engineering Selection Recommendations

BYW53-TAP Selection Criteria: The BYW53-TAP is a parametric equivalent to the BYX83TAP with identical electrical specifications, technology classification (Avalanche), and operating temperature range. Both components are manufactured by Vishay General Semiconductor - Diodes Division and are ROHS3 compliant. The primary difference is packaging format: BYW53-TAP is supplied in Cut Tape (CT) format versus Tape & Box (TB) for the BYX83TAP. Selection of BYW53-TAP is appropriate when Cut Tape packaging meets assembly requirements and inventory availability is prioritized (25,572 units in stock versus 756 units for BYX83TAP).

EGP20G Selection Criteria: The EGP20G is a manufacturer-recommended substitute manufactured by Fairchild Semiconductor. It meets the same voltage (400 V) and current (2 A) specifications but differs in technology classification (Standard versus Avalanche), package format (DO-15 versus SOD-57), and recovery characteristics (50 ns trr versus 4 µs trr). The EGP20G operates within a narrower temperature range (-65 to 150 °C versus -55 to 175 °C). Selection of EGP20G is appropriate when DO-15 package compatibility exists in the circuit design and faster recovery characteristics are acceptable. High inventory availability (36,600 units) supports supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can BYW53-TAP directly replace BYX83TAP in existing designs? A: Yes. BYW53-TAP is a parametric equivalent with identical voltage (400 V), current (2 A), forward voltage (1 V @ 1 A), reverse recovery time (4 µs), and reverse leakage (1 µA @ 400 V) specifications. Both use SOD-57 axial through-hole packages and operate across -55 to 175 °C. The only difference is packaging format (Cut Tape versus Tape & Box). No circuit redesign is required.

Q: What are the limitations of using EGP20G as a substitute? A: EGP20G uses a different package format (DO-15 instead of SOD-57), which may require PCB layout modifications. The component has faster recovery time (50 ns versus 4 µs), which may affect circuit behavior in applications sensitive to switching characteristics. Operating temperature range is narrower (-65 to 150 °C versus -55 to 175 °C). Forward voltage is higher (1.25 V @ 2 A versus 1 V @ 1 A), and reverse leakage is higher (5 µA versus 1 µA). EGP20G is classified as Standard technology rather than Avalanche.

Q: Are all three parts ROHS3 compliant? A: BYX83TAP and BYW53-TAP are explicitly ROHS3 compliant. EGP20G RoHS status is not specified in the provided data.

Q: What is the difference between Avalanche and Standard technology diodes? A: This information is not provided in the technical parameters. Selection between Avalanche (BYX83TAP, BYW53-TAP) and Standard (EGP20G) technology should be based on application-specific requirements.

Q: Can I use EGP20G in a circuit designed for SOD-57 package? A: No. EGP20G uses DO-15 package format, which has different physical dimensions and pin spacing than SOD-57. PCB layout and mechanical mounting modifications are required.

Q: Which substitute has the best inventory availability? A: EGP20G has the highest inventory (36,600 units), followed by BYW53-TAP (25,572 units), and BYX83TAP (756 units).
