SBT80-06J Equivalent & Substitute Parts

Part Overview

The SBT80-06J is a Schottky diode array manufactured by onsemi, configured as a 1 Pair Common Cathode arrangement with a maximum reverse voltage rating of 60 V and average rectified current of 8 A per diode. The device is packaged in a TO-220-3 Full Pack through-hole configuration and features fast recovery characteristics with a maximum forward voltage of 580 mV at 3 A.

The SBT80-06J is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this diode array is specified.

Substitute Part Grouping Explanation

Substitute parts for the SBT80-06J are identified based on strict electrical and mechanical parameter compatibility. The following criteria determine substitution eligibility:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (identical topology required)
• Technology: Schottky (same semiconductor technology)
• Voltage - DC Reverse (Vr) (Max): 60 V (equal or higher rating acceptable)
• Mounting Type: Through Hole (same mounting method)
• Package / Case: TO-220-3 Full Pack (identical package form factor)
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io) (same speed classification)

Secondary Compatibility Parameters:

• Current - Average Rectified (Io) (per Diode): Substitute must meet or exceed 8 A specification
• Voltage - Forward (Vf) (Max): Substitute must not exceed 580 mV at rated current
• Operating Temperature - Junction: Substitute must support the required temperature range
• Moisture Sensitivity Level (MSL): Substitute must be rated MSL 1 or equivalent

The RB205T-60 from Rohm Semiconductor meets all primary and secondary substitution criteria for the SBT80-06J.

Parameter Comparison

Engineering Selection Recommendations

The RB205T-60 is a direct substitute for the obsolete SBT80-06J. Both devices share identical electrical specifications for reverse voltage, forward voltage characteristics, and switching speed. Both are rated MSL 1 (Unlimited) and are REACH Unaffected.

The RB205T-60 carries Active product status from Rohm Semiconductor, ensuring ongoing availability and supply chain continuity. The RB205T-60 is RoHS3 Compliant, meeting current environmental and regulatory requirements.

The primary design consideration is the current rating difference: the RB205T-60 is rated at 7.5 A per diode compared to the SBT80-06J at 8 A per diode. This 0.5 A reduction must be evaluated against the specific application's current requirements. If the application operates at or below 7.5 A per diode, the RB205T-60 is fully compatible. If the application requires the full 8 A rating, alternative parts must be sourced.

The RB205T-60 exhibits higher reverse leakage current (600 µA @ 60 V) compared to the SBT80-06J (100 µA @ 30 V). This parameter difference must be assessed for applications sensitive to leakage current performance.

Frequently Asked Questions (FAQ)

Q: Can the RB205T-60 directly replace the SBT80-06J in all applications?

A: The RB205T-60 is electrically and mechanically compatible with the SBT80-06J for applications operating at 7.5 A or below per diode. Applications requiring the full 8 A rating must evaluate whether the 0.5 A reduction impacts circuit performance. Both devices share identical reverse voltage, forward voltage, and switching speed specifications.

Q: What is the significance of the current rating difference between these parts?

A: The SBT80-06J is rated at 8 A average rectified current per diode, while the RB205T-60 is rated at 7.5 A. This 0.5 A difference represents the maximum continuous current each device can safely conduct. Applications operating below 7.5 A experience no functional impact. Applications requiring sustained operation above 7.5 A must use the SBT80-06J or source alternative parts with higher current ratings.

Q: Are the package dimensions identical between these parts?

A: Both the SBT80-06J and RB205T-60 use the TO-220-3 Full Pack through-hole package. Physical dimensions, pin spacing, and mounting hole locations are identical, enabling direct PCB-level substitution without layout modifications.

Q: What is the difference in reverse leakage current between these parts?

A: The SBT80-06J exhibits 100 µA reverse leakage at 30 V, while the RB205T-60 exhibits 600 µA reverse leakage at 60 V. The RB205T-60 measurement is taken at the full rated voltage, which accounts for the higher value. Applications with strict leakage current requirements must evaluate whether this difference affects circuit performance.

Q: Why is the SBT80-06J classified as obsolete?

A: The SBT80-06J is no longer manufactured by onsemi. The RB205T-60 from Rohm Semiconductor is an active product with ongoing production and supply availability, making it the recommended substitute for new designs and component replenishment.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts are REACH Unaffected and carry MSL 1 (Unlimited) ratings. The RB205T-60 is additionally RoHS3 Compliant, meeting current environmental directives. Both parts carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.
