Key Parameters

Substitute Part Grouping Explanation

Substitution of the NSB8DTHE3_B/P is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 8 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C to 150°C
• Grade: Automotive
• Qualification: AEC-Q101

Voltage Rating Consideration: The NSB8DTHE3_B/P operates at 200 V DC reverse voltage. Substitute parts must maintain electrical compatibility within the application circuit. Parts with higher voltage ratings remain functionally compatible in circuits designed for 200 V operation.

Parameter Comparison

Engineering Selection Recommendations

The NSB8GTHM3/I is a direct substitute for the NSB8DTHE3_B/P based on the following engineering criteria:

Electrical Compatibility: Both devices share identical current ratings (8 A), forward voltage characteristics (1.1 V @ 8 A), recovery speed (Standard >500ns), and capacitance (55 pF @ 4V, 1MHz). The NSB8GTHM3/I features a higher reverse voltage rating (400 V versus 200 V), which provides enhanced voltage margin in the application circuit without degrading performance.

Package and Mounting Compatibility: Both parts utilize the TO-263AB (D2PAK) surface mount package with identical pinout and thermal characteristics, enabling direct PCB layout compatibility.

Compliance and Qualification: Both devices carry automotive-grade classification and AEC-Q101 qualification, meeting the same reliability and quality standards. The NSB8GTHM3/I maintains active product status, ensuring continued availability and supply chain stability.

Temperature Range: Identical operating temperature range (-55°C to 150°C junction temperature) ensures thermal performance equivalence across all operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the NSB8GTHM3/I replace the NSB8DTHE3_B/P in existing designs?

A: Yes. The NSB8GTHM3/I is electrically and mechanically compatible. Both devices share identical current ratings, forward voltage characteristics, recovery speed, and package configuration.
