BYT53F-TR Equivalent & Substitute Parts

Part Overview

The BYT53F-TR is an avalanche diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 300V DC reverse voltage and 1.9A average rectified current in a SOD-57 axial through-hole package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance is required but the original part is unavailable, when alternative packaging formats are acceptable, or when sourcing from different manufacturers is necessary to meet supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BYT53F-TR is determined by the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 300V minimum
• Current - Average Rectified (Io): 1.9A minimum
• Reverse Recovery Time (trr): 50ns or faster
• Current - Reverse Leakage @ Vr: 5µA or lower at rated voltage
• Mounting Type: Through Hole
• Speed Classification: Fast Recovery

Acceptable Variation Parameters:

• Forward Voltage (Vf): May exceed specified maximum if circuit design accommodates increased voltage drop
• Current - Average Rectified (Io): May exceed 1.9A (higher current rating is acceptable)
• Operating Temperature Range: May differ if application requirements are met within the substitute's range
• Package / Case: Alternative through-hole axial packages are acceptable if physical space permits

The EGP20F meets all critical matching parameters with equivalent or superior electrical specifications and maintains through-hole axial mounting compatibility.

Engineering Selection Recommendations

EGP20F as Substitute for BYT53F-TR:

The EGP20F is a valid electrical substitute based on the following criteria:

1. Voltage Rating: Both parts are rated for 300V DC reverse voltage, meeting the primary electrical requirement.

2. Current Capacity: The EGP20F provides 2A average rectified current, which exceeds the BYT53F-TR requirement of 1.9A, ensuring adequate current handling capability.

3. Switching Characteristics: Both parts exhibit identical 50ns reverse recovery time and fast recovery speed classification, maintaining equivalent switching performance.

4. Leakage Current: Both parts specify 5µA reverse leakage at 300V, ensuring equivalent reverse bias behavior.

5. Compliance Status: Both parts maintain REACH Unaffected status. The BYT53F-TR is RoHS3 compliant; RoHS status for the EGP20F is not specified in the provided data.

6. Product Status: Both parts are classified as Active, indicating current manufacturing availability.

Package Consideration: The EGP20F uses DO-15 packaging while the BYT53F-TR uses SOD-57 packaging. Both are axial through-hole formats. Physical board layout verification is required to confirm DO-15 package dimensions are compatible with the PCB footprint designed for SOD-57.

Temperature Range Consideration: The BYT53F-TR operates from -55°C to 175°C, while the EGP20F operates from -65°C to 150°C. Applications requiring operation above 150°C junction temperature cannot use the EGP20F as a substitute.

Frequently Asked Questions (FAQ)

Q: Can the EGP20F directly replace the BYT53F-TR without circuit modification?

A: The EGP20F meets all critical electrical parameters (voltage, current, switching speed, and leakage current). However, two factors require verification: (1) Physical package compatibility—the DO-15 package dimensions must fit the PCB footprint designed for SOD-57, and (2) Operating temperature range—if the application requires junction temperatures above 150°C, the EGP20F cannot be used.

Q: What is the difference between SOD-57 and DO-15 packages?

A: Both are axial through-hole diode packages with leads on opposite ends. SOD-57 and DO-15 (DO-204AC) have different physical dimensions and lead spacing. PCB footprint compatibility must be confirmed before substitution.

Q: Why is the forward voltage of the EGP20F higher than the BYT53F-TR?

A: The EGP20F forward voltage specification (1.25V @ 2A) is measured at a higher current level than the BYT53F-TR specification (1.1V @ 1A). Forward voltage increases with current. The higher specification value does not indicate inferior performance but reflects measurement at different operating conditions.

Q: Are there any compliance concerns when substituting the EGP20F for the BYT53F-TR?

A: The BYT53F-TR is RoHS3 compliant; the EGP20F RoHS status is not specified in the provided data. Both parts are REACH Unaffected. Compliance verification with your specific regulatory requirements is necessary before final component selection.

Q: What is the significance of the 50ns reverse recovery time for both parts?

A: The 50ns reverse recovery time indicates both parts are fast recovery diodes suitable for high-frequency switching applications. This parameter is identical between the BYT53F-TR and EGP20F, ensuring equivalent performance in circuits requiring rapid diode turn-off.

Q: Can the EGP20F be used in applications where the BYT53F-TR operates at maximum junction temperature?

A: No. The BYT53F-TR maximum junction temperature is 175°C, while the EGP20F maximum is 150°C. Applications designed to operate at or near 175°C junction temperature require the BYT53F-TR or an alternative substitute with equivalent or higher temperature rating.
