BYT60P-400 Equivalent & Substitute Parts

Part Overview

The BYT60P-400 is a diode array module manufactured by STMicroelectronics, configured as 2 independent rectifier diodes rated for 400 V DC reverse voltage and 60 A average rectified current per diode. The device is packaged in SOD-93-2 through-hole configuration and utilizes fast recovery diode technology with 100 ns reverse recovery time.

This part is classified as obsolete. Locating equivalent substitute components is necessary to support ongoing system maintenance, repair, and new design implementations where through-hole or chassis-mount diode array solutions are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BYT60P-400 is determined by the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Diode configuration: 2 independent diodes
• Voltage rating: 400 V DC reverse voltage (Vr)
• Current rating: 60 A average rectified current per diode
• Forward voltage: 1.5 V maximum at 60 A
• Technology classification: Fast recovery diode

Mechanical and Compliance Criteria:

• Mounting type compatibility (through-hole or chassis-mount)
• Package classification (SOD-93-2, SOT-227-4, or equivalent)
• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level 1 (unlimited)

The APT2X60D40J from Microchip Technology meets all electrical equivalence criteria and maintains full regulatory compliance. The primary difference is the mounting type (chassis-mount versus through-hole) and package form factor (SOT-227-4 miniBLOC versus SOD-93-2).

Parameter Comparison

Engineering Selection Recommendations

APT2X60D40J as Primary Substitute:

The APT2X60D40J is electrically equivalent to the BYT60P-400 across all critical parameters: 400 V reverse voltage rating, 60 A average rectified current per diode, and 1.5 V forward voltage at rated current. Both devices are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The APT2X60D40J offers superior performance characteristics: reverse recovery time of 37 ns compared to 100 ns in the BYT60P-400 provides faster switching behavior. The device is currently in active production status, ensuring long-term availability and supply chain stability.

Mounting and Package Considerations:

The primary design consideration is the transition from through-hole (SOD-93-2) to chassis-mount (SOT-227-4 miniBLOC) packaging. This substitution requires mechanical redesign of the mounting interface and PCB layout. The APT2X60D40J is supplied in tube packaging and is suitable for applications requiring direct chassis mounting with integrated thermal management.

Compliance and Regulatory Status:

Both devices maintain identical compliance certifications: RoHS3 compliant, REACH unaffected, and moisture sensitivity level 1. No additional regulatory or environmental qualification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the APT2X60D40J directly replace the BYT60P-400 without circuit modification?

A: Electrical substitution is valid. The APT2X60D40J maintains identical voltage and current ratings, forward voltage characteristics, and fast recovery diode performance. However, the mounting type differs: BYT60P-400 is through-hole while APT2X60D40J is chassis-mount. PCB layout and mechanical mounting must be redesigned accordingly.

Q: What is the significance of the reverse recovery time difference (100 ns vs. 37 ns)?

A: The APT2X60D40J exhibits faster reverse recovery time, resulting in reduced switching losses and improved efficiency in high-frequency rectification applications. This is a performance enhancement relative to the BYT60P-400 and does not create compatibility issues.

Q: Are there differences in reverse leakage current between these devices?

A: Yes. The APT2X60D40J specifies 250 µA reverse leakage at 400 V, compared to 60 µA for the BYT60P-400. This higher leakage current is within acceptable limits for standard rectifier applications and does not preclude substitution. Applications with stringent leakage requirements should evaluate this parameter against system specifications.

Q: Does the packaging change affect thermal management?

A: The APT2X60D40J chassis-mount SOT-227-4 miniBLOC package is designed for direct thermal coupling to a heat sink or chassis. The BYT60P-400 through-hole SOD-93-2 package relies on PCB thermal dissipation. The APT2X60D40J may provide superior thermal performance in applications with high current density due to direct chassis contact.

Q: Are both devices suitable for new design implementations?

A: The BYT60P-400 is obsolete and not recommended for new designs. The APT2X60D40J is in active production status and is the appropriate choice for new applications requiring 400 V, 60 A diode array functionality.

Q: What compliance certifications apply to both devices?

A: Both the BYT60P-400 and APT2X60D40J are RoHS3 compliant and REACH unaffected. Both devices have moisture sensitivity level 1 (unlimited), indicating no special moisture handling requirements during storage or assembly.
