MBR1630 Equivalent & Substitute Parts

Part Overview

The MBR1630 is a Schottky rectifier diode rated for 30 V DC reverse voltage and 16 A average rectified current in a Through Hole TO-220AC package. Manufactured by Diodes Incorporated, this component is classified as Obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The obsolete status of the MBR1630 makes substitute part selection critical for procurement continuity and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR1630 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) rating must equal or exceed 30 V
• Current - Average Rectified (Io) must equal or exceed 16 A
• Voltage - Forward (Vf) must be compatible at rated current
• Speed classification must maintain Fast Recovery characteristics
• Current - Reverse Leakage must be within acceptable limits

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (required)
• Package / Case: TO-220-2 or equivalent footprint
• Operating Temperature Range must support application requirements

Compliance Criteria:

• RoHS3 Compliance required
• Moisture Sensitivity Level (MSL) 1 acceptable

The MBR1635G from onsemi meets all substitution criteria with enhanced voltage rating (35 V) and extended temperature range (-65°C ~ 175°C), while maintaining identical current rating, forward voltage, and package configuration.

Engineering Selection Recommendations

MBR1635G Selection Basis:

The MBR1635G from onsemi is the primary substitute for the obsolete MBR1630. Selection is justified on the following engineering grounds:

1. Product Status: The MBR1635G maintains Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete MBR1630.

2. Electrical Equivalence: The substitute maintains identical current rating (16 A), forward voltage (630 mV @ 16 A), and fast recovery speed characteristics. The increased voltage rating (35 V vs. 30 V) provides design margin without introducing incompatibility.

3. Mechanical Compatibility: Both parts utilize identical TO-220-2 Through Hole packaging, ensuring direct PCB footprint compatibility without layout modifications.

4. Compliance Alignment: Both parts maintain ROHS3 Compliance and MSL 1 rating, satisfying regulatory and environmental requirements.

5. Temperature Performance: The MBR1635G extends the operating temperature range to -65°C ~ 175°C, providing enhanced thermal performance over the MBR1630's -65°C ~ 150°C range.

For applications operating within the MBR1630's original voltage and temperature specifications, the MBR1635G functions as a direct replacement with improved reliability margins.

Frequently Asked Questions (FAQ)

Q: Can the MBR1635G directly replace the MBR1630 in existing designs?

A: Yes. The MBR1635G is electrically and mechanically compatible with the MBR1630. Both parts share identical current rating (16 A), forward voltage (630 mV @ 16 A), fast recovery speed, and TO-220-2 package configuration. The higher voltage rating (35 V) of the substitute provides additional design margin without affecting circuit operation.

Q: What is the primary reason for substituting the MBR1630?

A: The MBR1630 is classified as Obsolete. The MBR1635G is an Active product from onsemi, ensuring continued availability and supply chain reliability for new designs and production requirements.

Q: Are there package differences between the MBR1630 and MBR1635G?

A: No. Both parts use the TO-220-2 Through Hole package. The MBR1630 is supplied as TO-220AC, and the MBR1635G is supplied as TO-220-2; both designations refer to the same two-lead TO-220 package configuration suitable for identical PCB layouts.

Q: How do the electrical specifications compare?

A: The MBR1635G maintains identical performance in current handling (16 A), forward voltage drop (630 mV @ 16 A), and switching speed (Fast Recovery ≤ 500ns). The reverse voltage rating increases from 30 V to 35 V, and the maximum junction temperature extends from 150°C to 175°C, both representing performance enhancements.

Q: Are both parts RoHS compliant?

A: Yes. Both the MBR1630 and MBR1635G are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory standards.

Q: What is the reverse leakage current specification for the MBR1635G?

A: The MBR1635G specifies 200 µA reverse leakage current at its rated voltage (35 V), matching the leakage characteristic of the MBR1630 at 30 V and maintaining equivalent circuit performance.
