Substitute Part Grouping Explanation

Substitution eligibility for the BYG20JHM3_A/I is determined by strict equivalence across the following parameters:

Electrical Parameters (Must Match Exactly):

Voltage - DC Reverse (Vr) (Max): 600 V
Current - Average Rectified (Io): 1.5 A
Voltage - Forward (Vf) (Max) @ If: 1.4 V @ 1.5 A
Reverse Recovery Time (trr): 75 ns
Current - Reverse Leakage @ Vr: 1 µA @ 600 V
Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Mechanical Parameters (Must Match Exactly):

Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C ~ 150°C

Compliance Parameters (Must Match Exactly):

Technology: Avalanche
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)
Product Status: Active

All identified substitute parts maintain identical electrical and mechanical specifications. Variations in packaging configuration (Tape & Reel versus Cut Tape & Digi-Reel®) and manufacturing designations do not affect functional equivalence when all electrical parameters and package dimensions remain constant.

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full compliance with ROHS3 and REACH requirements. The BYG20JHM3_A/I, BYG20JHE3_A/H, and BYG20JHE3_A/I variants carry automotive-grade qualification under AEC-Q101, suitable for applications requiring automotive-level reliability and traceability. The BYG20J-E3/TR and BYG20J-E3/TR3 variants provide equivalent electrical performance and mechanical compatibility without automotive-specific qualification.

Selection between substitute parts is determined by application requirements for automotive qualification and packaging configuration availability. All parts share identical electrical characteristics, thermal operating range, and surface mount DO-214AC package dimensions, enabling direct functional substitution within circuit designs.

Frequently Asked Questions (FAQ)

Q: Can BYG20J-E3/TR be used as a direct replacement for BYG20JHM3_A/I?

A: Yes. Both parts maintain identical electrical parameters (600 V reverse voltage, 1.5 A average rectified current, 75 ns reverse recovery time, 1.4 V forward voltage at 1.5 A), identical mechanical package specifications (DO-214AC, SMA surface mount), and identical operating temperature range (-55°C to 150°C). The primary difference is packaging configuration (Cut Tape & Digi-Reel® versus Tape & Reel) and absence of automotive-grade AEC-Q101 qualification on the BYG20J-E3/TR variant.

Q: What is the difference between BYG20JHE3_A/H and BYG20JHE3_A/I?

A: Both parts are electrically and mechanically identical. The designation suffix (_A/H versus _A/I) indicates different manufacturing or distribution batches within the same base product specification. All electrical parameters, package dimensions, and compliance certifications are equivalent.

Q: Are automotive-qualified variants required for all applications?

A: Automotive-grade qualification (AEC-Q101) is required only for applications subject to automotive industry standards and traceability requirements. The BYG20JHM3_A/I, BYG20JHE3_A/H, and BYG20JHE3_A/I carry this qualification. Non-automotive applications may use BYG20J-E3/TR or BYG20J-E3/TR3 variants without functional impact.

Q: Does packaging configuration (Tape & Reel versus Cut Tape & Digi-Reel®) affect electrical performance?

A: No. Packaging configuration affects only handling, storage, and supply chain logistics. All electrical parameters, mechanical dimensions, and performance characteristics remain identical across all packaging variants.

Q: Are all substitute parts currently in active production?

A: Yes. All identified substitute parts maintain Active product status with Vishay General Semiconductor - Diodes Division.
