MBR3060PT Equivalent & Substitute Parts

Part Overview

The MBR3060PT is an active Schottky diode array manufactured by onsemi, configured as a 1 Pair Common Cathode rectifier with a maximum reverse voltage rating of 60 V and average rectified current of 30 A per diode. The device is packaged in a Through Hole TO-247-3 case and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). This component is used in power conversion and rectification applications requiring fast recovery characteristics and low forward voltage drop. Equivalent and substitute parts are identified for applications where the MBR3060PT is unavailable, discontinued, or where alternative electrical specifications within acceptable parameters are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR3060PT is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 60 V (minimum requirement)
• Mounting Type: Through Hole
• Package / Case: TO-247-3 or equivalent mechanical footprint (TO-247AD, TO-3P-3, SC-65-3)

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 30 A
• Voltage - Forward (Vf) (Max) @ If: Within acceptable range for application
• Current - Reverse Leakage @ Vr: Within acceptable range for application
• Operating Temperature - Junction: Must support -65°C to 150°C minimum

Substitute parts MBR3060PT-E3/45 and STPS3060CW meet the critical parameters but exhibit reduced current ratings (20 A and 15 A respectively) compared to the main part. These substitutes are valid only for applications where the reduced current rating is acceptable within the circuit design constraints.

Parameter Comparison

Engineering Selection Recommendations

MBR3060PT (onsemi): Primary selection for applications requiring 30 A average rectified current per diode at 60 V reverse voltage. Active product status with full compliance to ROHS3 and REACH regulations. Unlimited moisture sensitivity level (MSL 1) permits standard handling and storage procedures.

MBR3060PT-E3/45 (Vishay General Semiconductor - Diodes Division): Valid substitute where circuit design accommodates 20 A average rectified current per diode. Maintains identical reverse voltage rating (60 V), forward voltage characteristics (750 mV @ 20 A), and reverse leakage current (5 mA @ 60 V). Active product status with ROHS3 compliance and unlimited MSL. Package variants (TO-3P-3, SC-65-3) are mechanically compatible with TO-247-3 footprint in Through Hole applications.

STPS3060CW (STMicroelectronics): Valid substitute where circuit design accommodates 15 A average rectified current per diode. Maintains identical reverse voltage rating (60 V) and fast recovery speed characteristics. Forward voltage is elevated to 850 mV @ 15 A compared to 750 mV @ 20 A in the main part. Reverse leakage current is reduced to 150 µA @ 60 V. Active product status with ROHS3 compliance and unlimited MSL. Package (TO-247-3) provides direct mechanical compatibility.

All three parts are active products with ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory compliance and standard handling procedures across all substitution options.

Frequently Asked Questions (FAQ)

Q: Can MBR3060PT-E3/45 be used as a direct replacement for MBR3060PT?

A: MBR3060PT-E3/45 is a valid substitute only if the circuit design accommodates a reduced average rectified current of 20 A per diode instead of 30 A. The reverse voltage rating (60 V), forward voltage characteristics (750 mV @ 20 A), and reverse leakage current (5 mA @ 60 V) are identical. Verify that the application current requirements do not exceed 20 A per diode before substitution.

Q: What is the primary difference between STPS3060CW and MBR3060PT?

A: STPS3060CW has a reduced average rectified current rating of 15 A per diode compared to 30 A in MBR3060PT. Additionally, STPS3060CW exhibits a higher forward voltage of 850 mV @ 15 A versus 750 mV @ 20 A in MBR3060PT, and lower reverse leakage current of 150 µA @ 60 V versus 5 mA @ 60 V. The reverse voltage rating (60 V) and fast recovery speed characteristics remain identical.

Q: Are the package variants (TO-3P-3, SC-65-3) of MBR3060PT-E3/45 compatible with the TO-247-3 footprint?

A: MBR3060PT-E3/45 is supplied in TO-3P-3 and SC-65-3 package variants. These are mechanically compatible with TO-247-3 Through Hole applications, as they share the same pin configuration and mounting requirements. Verify PCB layout and mechanical clearances before substitution.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Diode Configuration: 1 Pair Common Cathode, (2) Technology: Schottky, (3) Voltage - DC Reverse (Vr) (Max): 60 V minimum, (4) Mounting Type: Through Hole, and (5) Package / Case: TO-247-3 or equivalent mechanical footprint. Current rating, forward voltage, and reverse leakage current may vary within acceptable application limits.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MBR3060PT, MBR3060PT-E3/45, and STPS3060CW are all ROHS3 compliant with REACH unaffected status. All parts have unlimited moisture sensitivity level (MSL 1), permitting standard handling and storage procedures without special environmental controls.

Q: What is the operating temperature range for each part?

A: MBR3060PT and MBR3060PT-E3/45 both support -65°C to 150°C junction temperature range. STPS3060CW specifies a maximum junction temperature of 150°C; minimum operating temperature is not specified in the provided data. Verify minimum temperature requirements for your application before selecting STPS3060CW.

Q: Can these parts be used interchangeably in high-current applications?

A: No. Current ratings differ significantly: MBR3060PT (30 A), MBR3060PT-E3/45 (20 A), and STPS3060CW (15 A). Selection must be based on the actual circuit current requirements. Using a part with insufficient current rating will result in thermal stress and potential device failure.
