AS3BJ-M3/5BT Equivalent & Substitute Parts

Part Overview

The AS3BJ-M3/5BT is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 600 V DC reverse voltage with a 3 A average rectified current rating and is packaged in the DO-214AA (SMB) form factor. The device is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to packaging format availability, inventory considerations, or supply chain requirements.

Substitute Part Grouping Explanation

Substitute parts for the AS3BJ-M3/5BT are identified based on matching electrical specifications and mechanical compatibility. The primary substitution criterion is equivalence across all key electrical parameters: reverse voltage rating, average rectified current, forward voltage drop, reverse recovery time, reverse leakage current, and junction capacitance. All substitute parts must maintain the same DO-214AA (SMB) package form factor and surface mount mounting type to ensure mechanical and thermal compatibility with existing PCB designs.

The AS3BJ-M3/5BT and its substitute share the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.05 V @ 3 A
• Reverse Recovery Time (trr): 1.5 µs
• Current - Reverse Leakage @ Vr: 20 µA @ 600 V
• Capacitance @ Vr, F: 40 pF @ 4V, 1MHz
• Package / Case: DO-214AA, SMB
• Operating Temperature - Junction: -55°C to 175°C

Substitution differences are limited to packaging format (Tape & Reel versus Cut Tape) and inventory availability, which do not affect electrical performance or circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

The AS3BJ-M3/5BT and AS3BJ-M3/52T are electrically and mechanically equivalent. Both devices are manufactured by Vishay General Semiconductor - Diodes Division and maintain Active product status. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent environmental and regulatory compliance.

Selection between these parts is determined by packaging format requirements and supply chain availability. The AS3BJ-M3/5BT is supplied in Tape & Reel (TR) format, suitable for automated assembly processes requiring continuous reel feeding. The AS3BJ-M3/52T is supplied in Cut Tape (CT) format, suitable for manual assembly, kit builds, or applications requiring smaller quantity dispensing. Both formats contain identical diode components with no electrical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Are AS3BJ-M3/5BT and AS3BJ-M3/52T electrically identical?

A: Yes. Both parts share identical electrical specifications including 600 V reverse voltage rating, 3 A average rectified current, 1.05 V forward voltage drop at 3 A, 1.5 µs reverse recovery time, and 20 µA reverse leakage current at 600 V. Electrical performance in circuit operation is equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments, typically used for manual assembly, prototyping, or lower-volume production. The diode component itself is identical in both formats.

Q: Can I substitute AS3BJ-M3/52T for AS3BJ-M3/5BT in my design?

A: Yes, provided your assembly process accommodates Cut Tape format. The electrical and mechanical specifications are equivalent. Verify that your assembly equipment or manual assembly process is compatible with the Cut Tape format before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both AS3BJ-M3/5BT and AS3BJ-M3/52T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for these diodes?

A: Both parts operate across a junction temperature range of -55°C to 175°C, providing equivalent thermal performance across industrial and commercial temperature environments.

Q: Do these parts have moisture sensitivity concerns?

A: No. Both parts carry MSL 1 (Unlimited) classification, indicating unlimited shelf life without moisture bake-out requirements prior to soldering.
