Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MURS3JB-TP are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 3 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The MURS360BT3G manufactured by onsemi meets all critical electrical specifications and package requirements, qualifying it as a direct substitute. Both components operate within the same voltage and current ratings, share identical forward voltage characteristics, and are housed in the same DO-214AA SMB surface mount package. Both components maintain RoHS3 compliance and MSL Level 1 classification.

Parameter Comparison

Engineering Selection Recommendations

Both the MURS3JB-TP and MURS360BT3G are Active product status components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability, packaging format, and application-specific thermal requirements.

MURS3JB-TP (Micro Commercial Co):

• Tape & Reel (TR) packaging format
• Operating temperature range: -55°C to 150°C
• Reverse recovery time: 50 ns
• Reverse leakage current: 10 µA @ 600 V

MURS360BT3G (onsemi):

• Cut Tape (CT) & Digi-Reel® packaging format
• Operating temperature range: -65°C to 175°C
• Reverse recovery time: 75 ns
• Reverse leakage current: 3 µA @ 600 V

Both components satisfy the core electrical requirements for 600 V, 3 A general-purpose rectification applications. The MURS360BT3G offers extended temperature range capability and lower reverse leakage characteristics. Selection should account for packaging requirements, thermal operating conditions, and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can MURS360BT3G replace MURS3JB-TP in all applications?

A: Yes, the MURS360BT3G meets all critical electrical specifications: 600 V reverse voltage rating, 3 A average rectified current, and 1.25 V forward voltage at 3 A. Both components are housed in DO-214AA SMB surface mount packages and are RoHS3 compliant. The substitute part offers lower reverse leakage current and extended operating temperature range.

Q: What is the difference in packaging between these parts?

A: The MURS3JB-TP is supplied in Tape & Reel (TR) format, while the MURS360BT3G is available in Cut Tape (CT) & Digi-Reel® format. Both use the same DO-214AA SMB physical package for surface mount assembly. Packaging format selection depends on production volume and assembly equipment compatibility.

Q: Are there differences in reverse recovery time between these diodes?

A: The MURS3JB-TP specifies 50 ns reverse recovery time, while the MURS360BT3G specifies 75 ns. Both components are classified as Fast Recovery diodes with recovery time ≤ 500 ns at currents > 200 mA. The difference of 25 ns is within the fast recovery classification and does not affect general-purpose rectification applications.

Q: What is the reverse leakage current difference?

A: The MURS3JB-TP has reverse leakage current of 10 µA @ 600 V, while the MURS360BT3G has 3 µA @ 600 V. The MURS360BT3G exhibits lower leakage, which may provide improved performance in low-current or high-impedance circuit applications.

Q: Do both parts have the same temperature operating range?

A: No. The MURS3JB-TP operates from -55°C to 150°C junction temperature, while the MURS360BT3G operates from -65°C to 175°C. The MURS360BT3G provides extended temperature range capability for applications requiring operation at lower or higher temperatures.

Q: Are both parts RoHS3 compliant?

A: Yes, both the MURS3JB-TP and MURS360BT3G are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both components are REACH unaffected and carry EAR99 ECCN classification.
