SK83L-TP Equivalent & Substitute Parts

Part Overview

The SK83L-TP is a Schottky rectifier diode rated for 30 V DC reverse voltage and 8 A average rectified current in a Surface Mount SMC (DO-214AB) package. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product roadmap. Equivalent and substitute parts are necessary for applications requiring continued sourcing, design flexibility, or performance optimization within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SK83L-TP are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Voltage Rating: Minimum 30 V DC reverse voltage (Vr) to maintain circuit protection and reliability
• Package Type: DO-214AB (SMC) surface mount package for mechanical and thermal compatibility
• Technology: Schottky diode technology for consistent switching characteristics
• Fast Recovery Speed: ≤ 500ns recovery time for high-frequency rectification performance
• Operating Temperature Range: Compatibility with the -55°C to 150°C junction temperature specification

The substitute parts listed below meet these core electrical and mechanical requirements. However, current rating differences exist: the MBRS330T3G and SS33-E3/57T are rated for 3 A average rectified current, which is lower than the SK83L-TP's 8 A rating. These substitutes are suitable for applications with reduced current demands or as design alternatives where the full 8 A capacity is not required.

Parameter Comparison

Engineering Selection Recommendations

MBRS330T3G (onsemi): This part is classified as Active and carries ROHS3 compliance with Moisture Sensitivity Level 1 (Unlimited). It provides extended operating temperature range (-65°C to 150°C) compared to the SK83L-TP. The MBRS330T3G is suitable for applications where the 3 A current rating is sufficient and long-term component availability is required. The lower forward voltage (500 mV @ 3 A) offers improved efficiency in lower-current circuits.

SS33-E3/57T (Vishay General Semiconductor - Diodes Division): This part is classified as Active and carries ROHS3 compliance with Moisture Sensitivity Level 1 (Unlimited). It maintains the same operating temperature lower bound as the SK83L-TP (-55°C) but with a reduced upper limit (125°C versus 150°C). The SS33-E3/57T exhibits superior reverse leakage characteristics (500 µA @ 30 V) compared to both the SK83L-TP and MBRS330T3G, making it suitable for low-leakage applications. This part is supplied in Tape & Reel (TR) packaging format.

Both substitute parts are Active products with established supply chains, making them preferable to the SK83L-TP for new designs or continued production requiring long-term sourcing stability.

Frequently Asked Questions (FAQ)

Q: Can the MBRS330T3G or SS33-E3/57T directly replace the SK83L-TP in existing designs?

A: Direct replacement depends on circuit current requirements. Both substitutes are rated for 3 A average rectified current, compared to the SK83L-TP's 8 A rating. If the application draws less than 3 A, direct substitution is electrically valid. If the application requires the full 8 A capacity, these substitutes are not suitable without circuit redesign.

Q: Are the substitute parts mechanically compatible with SK83L-TP PCB layouts?

A: Yes. Both MBRS330T3G and SS33-E3/57T use the DO-214AB (SMC) surface mount package, which is mechanically and thermally identical to the SK83L-TP package. PCB footprints and reflow soldering profiles remain unchanged.

Q: What is the difference in forward voltage between these parts?

A: The SK83L-TP exhibits 650 mV forward voltage at 8 A, while both MBRS330T3G and SS33-E3/57T exhibit 500 mV forward voltage at 3 A. Forward voltage comparisons are valid only at equivalent current levels. At lower currents, the SK83L-TP forward voltage would be lower than 650 mV, and the substitute parts' forward voltage would be lower than 500 mV.

Q: Which substitute part has better reverse leakage performance?

A: The SS33-E3/57T exhibits the lowest reverse leakage at 500 µA @ 30 V, followed by the SK83L-TP at 1 mA @ 30 V, and the MBRS330T3G at 2 mA @ 30 V. Lower reverse leakage is beneficial in precision analog circuits and low-power applications.

Q: What is the difference in operating temperature range?

A: The MBRS330T3G supports -65°C to 150°C, the SK83L-TP supports -55°C to 150°C, and the SS33-E3/57T supports -55°C to 125°C. The MBRS330T3G provides the widest temperature range, while the SS33-E3/57T has the most restricted upper temperature limit.

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

A: Both MBRS330T3G and SS33-E3/57T are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). The SK83L-TP is Not For New Designs. All three parts carry REACH Unaffected status and EAR99 ECCN classification.

Q: What packaging formats are available for the substitute parts?

A: The MBRS330T3G is supplied in Cut Tape (CT) & Digi-Reel® format. The SS33-E3/57T is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly equipment compatibility.
