Electrical Parameters (Must Match):

Voltage - DC Reverse (Vr) (Max): 300 V
Current - Average Rectified (Io): 500 mA
Voltage - Forward (Vf) (Max) @ If: 1.35 V @ 500 mA
Reverse Recovery Time (trr): 50 ns
Current - Reverse Leakage @ Vr: 5 µA @ 300 V
Capacitance @ Vr, F: 7 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

Package / Case: DO-213AA (Glass)
Mounting Type: Surface Mount

Compliance & Qualification (Must Match):

Engineering Selection Recommendations

The BYM07-300-E3/98 is a direct parametric equivalent to the BYM07-300HE3_A/I. Both devices are manufactured by Vishay General Semiconductor - Diodes Division, belong to the SUPERECTIFIER® series, and maintain Active product status. Both parts are ROHS3 compliant and REACH unaffected, satisfying identical regulatory requirements.

The primary distinction between the two parts is packaging configuration. The BYM07-300HE3_A/I is supplied in standard packaging, while the BYM07-300-E3/98 is supplied in Tape & Reel (TR) format. This difference affects inventory management and automated assembly processes but does not alter electrical performance or mechanical compatibility.

Selection between these parts is determined by supply chain requirements, inventory availability, and assembly methodology. Both parts are suitable for applications requiring 300 V, 500 mA fast recovery rectification with automotive-grade qualification.

Frequently Asked Questions (FAQ)

Q: Can the BYM07-300-E3/98 be used as a direct replacement for the BYM07-300HE3_A/I?

A: Yes. The BYM07-300-E3/98 is a parametric equivalent substitute. All electrical specifications, mechanical dimensions, package type, and compliance certifications are identical between the two parts.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The BYM07-300HE3_A/I uses standard packaging, while the BYM07-300-E3/98 is supplied in Tape & Reel (TR) format. This affects order quantities and assembly automation compatibility but does not impact electrical performance.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the BYM07-300HE3_A/I and BYM07-300-E3/98 carry AEC-Q101 automotive qualification and are classified as Active products by Vishay General Semiconductor - Diodes Division.

Q: Do these parts have identical thermal characteristics?

A: Yes. Both parts operate across the same junction temperature range of -65°C to 175°C and share identical reverse recovery time (50 ns) and leakage current specifications (5 µA @ 300 V).

Q: Can these parts be used interchangeably on the same PCB?
