SBT80-06LS Equivalent & Substitute Parts

Part Overview

The SBT80-06LS is a Schottky diode array manufactured by onsemi, configured as 1 pair common cathode with a maximum reverse voltage of 60 V and average rectified current of 8 A per diode. The device is packaged in TO-220-3 Full Pack for through-hole mounting applications. This part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBT80-06LS is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode configuration must be 1 pair common cathode
• Technology must be Schottky
• Maximum reverse voltage (Vr) must be 60 V or greater
• Average rectified current (Io) per diode must be 8 A or greater
• Forward voltage (Vf) characteristics must be compatible at specified current levels
• Recovery speed must be fast recovery ≤ 500ns, > 200mA (Io)

Mechanical Compatibility Requirements:

• Mounting type must be through hole
• Package must be TO-220-3 Full Pack format

Environmental & Compliance Requirements:

• Moisture sensitivity level must be 1 (Unlimited)
• REACH status must be REACH Unaffected

The RB205T-60 from Rohm Semiconductor meets all electrical and mechanical compatibility criteria for substitution with the SBT80-06LS.

Parameter Comparison

Engineering Selection Recommendations

The RB205T-60 is a direct substitute for the SBT80-06LS based on the following factors:

Electrical Equivalence: The RB205T-60 maintains the same reverse voltage rating (60 V), diode configuration (1 pair common cathode), and Schottky technology. Forward voltage characteristics are equivalent at the specified test points. Recovery speed specifications are identical.

Current Rating Consideration: The RB205T-60 is rated for 7.5 A average rectified current per diode, compared to the SBT80-06LS rating of 8 A. This represents a 6.25% reduction in current capacity. Applications operating at or below 7.5 A per diode are fully compatible. Applications requiring the full 8 A rating must be evaluated against actual circuit current demands.

Reverse Leakage: The RB205T-60 exhibits 600 µA reverse leakage at 60 V, compared to 100 µA at 10 V for the SBT80-06LS. This difference reflects measurement at different voltage levels and does not preclude substitution in standard rectification applications.

Compliance and Availability: The RB205T-60 is actively manufactured with ROHS3 compliance and REACH unaffected status. The SBT80-06LS is obsolete, making the RB205T-60 the appropriate selection for new designs and ongoing procurement.

Package and Mounting: Both devices use identical TO-220-3 Full Pack through-hole packaging, ensuring direct mechanical compatibility without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the RB205T-60 be used as a direct replacement for the SBT80-06LS in existing designs?

A: The RB205T-60 is mechanically and electrically compatible for applications where the diode current does not exceed 7.5 A per device. The identical TO-220-3 package allows direct PCB mounting without modification. Verify that circuit current requirements do not exceed the 7.5 A rating of the substitute.

Q: What is the significance of the current rating difference between 8 A and 7.5 A?

A: The SBT80-06LS is rated for 8 A average rectified current per diode, while the RB205T-60 is rated for 7.5 A. This 0.5 A difference represents a 6.25% reduction in maximum current capacity. Applications operating below 7.5 A are unaffected. Applications requiring sustained operation at 8 A must be evaluated against actual circuit demands to determine if the lower rating presents a limitation.

Q: Are the forward voltage characteristics equivalent between these devices?

A: Both devices specify a maximum forward voltage of 580 mV. The SBT80-06LS specifies this value at 3 A, while the RB205T-60 specifies it at 7.5 A. The equivalent forward voltage rating confirms compatibility for rectification applications.

Q: Does the higher reverse leakage current of the RB205T-60 affect circuit performance?

A: The RB205T-60 exhibits 600 µA reverse leakage at 60 V, compared to 100 µA at 10 V for the SBT80-06LS. These measurements are taken at different voltage levels. In standard rectification applications, this difference does not affect circuit performance. Applications with stringent leakage requirements should evaluate the specific operating voltage and current conditions.

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

A: Both devices are REACH unaffected and have MSL rating of 1 (Unlimited). The RB205T-60 carries ROHS3 compliance, while the SBT80-06LS is obsolete. For new designs and procurement, the RB205T-60 is the appropriate selection.

Q: Can these devices be used interchangeably in high-temperature applications?

A: Both devices support a maximum junction temperature of 150°C. The SBT80-06LS specifies an operating range of -55°C to 150°C, while the RB205T-60 specifies 150°C as the maximum only. For applications requiring operation below -55°C, verify the RB205T-60 minimum operating temperature against specific circuit requirements.

Q: Is the TO-220-3 package identical between both devices?

A: Yes, both the SBT80-06LS and RB205T-60 use the TO-220-3 Full Pack package for through-hole mounting. No PCB layout modifications are required for substitution.
