BYT53C-TR Equivalent & Substitute Parts

Part Overview

The BYT53C-TR is an avalanche diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 150V DC reverse voltage and 1.9A average rectified current. This component is packaged in SOD-57 axial configuration and is classified as a fast recovery diode with a reverse recovery time of 50 nanoseconds. The part maintains Active product status and is RoHS3 compliant with REACH unaffected designation.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining through-hole mounting compatibility and thermal operating specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the BYT53C-TR is determined by the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 150V
• Current - Average Rectified (Io): Must equal or exceed 1.9A
• Reverse Recovery Time (trr): Must equal or be faster than 50ns
• Current - Reverse Leakage @ Vr: Must not exceed 5µA @ 150V
• Mounting Type: Through Hole configuration required
• Speed Classification: Fast Recovery performance required

Secondary Compatibility Factors:

• Operating Temperature Range: Substitute must support minimum -55°C junction temperature
• Package Configuration: Axial through-hole packages acceptable
• Compliance Status: Active product status and RoHS compliance required

The EGP20C meets all primary substitution criteria with equivalent reverse voltage, superior current rating, matching reverse recovery time, and identical reverse leakage characteristics. Package differences between SOD-57 and DO-15 are acceptable within through-hole axial mounting category.

Engineering Selection Recommendations

EGP20C as Primary Substitute:

The EGP20C is designated as the manufacturer-recommended substitute for the BYT53C-TR. This substitution is valid based on the following engineering factors:

1. Electrical Equivalence: Both components maintain identical reverse voltage (150V), reverse recovery time (50ns), and reverse leakage current (5µA @ 150V) specifications. The EGP20C provides superior current handling (2A versus 1.9A), establishing it as a direct functional replacement within the 150V fast recovery diode category.

2. Compliance Status: The BYT53C-TR is confirmed Active product status with ROHS3 compliance and REACH unaffected designation. The EGP20C maintains Active product status with REACH unaffected status, ensuring regulatory continuity.

3. Thermal Considerations: The BYT53C-TR operates across -55°C to 175°C junction temperature range. The EGP20C operates across -65°C to 150°C. Applications requiring operation above 150°C junction temperature require the BYT53C-TR. Applications within -55°C to 150°C range support either component.

4. Package Compatibility: Both components utilize through-hole axial mounting. SOD-57 and DO-15 packages are mechanically distinct but functionally equivalent for circuit board integration. PCB layout modifications may be required due to different lead spacing and body dimensions.

Frequently Asked Questions (FAQ)

Q: Can the EGP20C directly replace the BYT53C-TR in all applications?

A: The EGP20C provides electrical substitution for applications operating within -55°C to 150°C junction temperature range. Applications requiring sustained operation above 150°C junction temperature require the BYT53C-TR. Physical package differences (SOD-57 versus DO-15) necessitate PCB layout verification.

Q: What are the key electrical differences between these components?

A: Both components share identical reverse voltage (150V), reverse recovery time (50ns), and reverse leakage current (5µA @ 150V) specifications. The EGP20C provides higher average rectified current (2A versus 1.9A) and lower forward voltage drop (950mV @ 2A versus 1.1V @ 1A), resulting in reduced power dissipation in the substitute component.

Q: Are there package dimension considerations for substitution?

A: Yes. The BYT53C-TR uses SOD-57 axial package while the EGP20C uses DO-15 axial package. Although both are through-hole axial configurations, physical dimensions differ. Lead spacing, body length, and diameter variations require PCB footprint verification before substitution.

Q: What is the temperature operating range difference?

A: The BYT53C-TR operates from -55°C to 175°C junction temperature. The EGP20C operates from -65°C to 150°C junction temperature. The EGP20C provides lower temperature capability but reduced upper temperature limit. Verify application thermal requirements against these ranges.

Q: Are both components RoHS compliant?

A: The BYT53C-TR is confirmed ROHS3 compliant. The EGP20C RoHS status is not specified in available documentation. Applications requiring verified RoHS compliance should confirm EGP20C compliance status with the supplier before substitution.

Q: What is the reverse recovery time significance for these diodes?

A: Both components specify 50 nanosecond reverse recovery time, classifying them as fast recovery diodes. This parameter determines switching speed in high-frequency applications. Identical specifications ensure equivalent performance in fast switching circuits.

Q: Can the EGP20C handle the same current as the BYT53C-TR?

A: The EGP20C exceeds the BYT53C-TR current rating (2A versus 1.9A). This provides design margin and allows the substitute to handle equivalent or higher current loads without derating.
