• Mounting Type: Surface Mount
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: 445 mV to 500 mV @ 2 A
• Current - Reverse Leakage @ Vr: 400 µA to 1 mA @ 30 V
• Operating Temperature - Junction: -65°C to -55°C minimum; 125°C to 150°C maximum
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Digi-Reel®

All substitute parts listed maintain identical electrical performance within the specified operating envelope and are housed in mechanically compatible DO-214AA (SMB) packages suitable for direct PCB replacement.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Identical Electrical and Thermal Specifications):

SS23-E3/52T (Vishay General Semiconductor - Diodes Division) and SS23 (Taiwan Semiconductor Corporation) are parametric equivalents to the SS23-M3/5BT. These parts maintain identical voltage, current, forward voltage, reverse leakage, and junction temperature ratings. Selection between these options is determined by packaging format availability: SS23-E3/52T is supplied in Cut Tape (CT) & Digi-Reel® format, while SS23-M3/5BT and SS23 are supplied in Tape & Reel (TR) format. All three parts are ROHS3 compliant, MSL 1 (Unlimited), and REACH Unaffected.

Manufacturer-Recommended Alternatives (Functionally Compatible with Minor Parameter Variations):

B130LB-13-F (Diodes Incorporated), B230-13-F (Diodes Incorporated), and MBRS230LT3G (onsemi) are manufacturer-recommended alternatives that maintain the 30 V / 2 A electrical specification and DO-214AA (SMB) package compatibility. These parts exhibit acceptable variations in forward voltage (445 mV to 500 mV), reverse leakage current (500 µA to 1 mA), and minimum junction temperature (-55°C versus -65°C). All substitute parts are ROHS3 compliant, MSL 1 (Unlimited), and REACH Unaffected, ensuring regulatory and environmental compliance equivalence.

B230-13-F offers extended maximum junction temperature rating (-65°C ~ 150°C) compared to the primary part (-65°C ~ 125°C), providing thermal margin in high-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can SS23-E3/52T be used as a direct replacement for SS23-M3/5BT?

A: Yes. SS23-E3/52T is a parametric equivalent with identical electrical specifications (30 V, 2 A, 500 mV forward voltage, 400 µA reverse leakage, -65°C ~ 125°C junction temperature). The only difference is packaging format: SS23-E3/52T is supplied in Cut Tape (CT) & Digi-Reel® while SS23-M3/5BT is supplied in Tape & Reel (TR). Both are mechanically compatible DO-214AA (SMB) packages suitable for direct PCB replacement.

Q: What is the difference between B130LB-13-F and B230-13-F?

A: Both parts are 30 V / 2 A Schottky diodes in DO-214AA (SMB) packages from Diodes Incorporated. B130LB-13-F has a lower forward voltage (445 mV @ 2 A) and lower reverse leakage (1 mA @ 30 V) with a narrower junction temperature range (-55°C ~ 125°C). B230-13-F has a forward voltage of 500 mV @ 2 A, reverse leakage of 500 µA @ 30 V, and an extended maximum junction temperature of 150°C. Selection depends on thermal requirements and leakage current specifications for the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (SS23-E3/52T, B130LB-13-F, B230-13-F, MBRS230LT3G, and SS23) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, matching the compliance profile of the SS23-M3/5BT.

Q: Can I use MBRS230LT3G in place of SS23-M3/5BT?

A: Yes, with the following considerations. MBRS230LT3G maintains the 30 V / 2 A electrical specification and DO-214AA (SMB) package compatibility. However, it has a higher reverse leakage current (1 mA @ 30 V versus 400 µA @ 30 V) and a lower minimum junction temperature (-55°C versus -65°C). These variations are within acceptable operating parameters for most applications but should be verified against specific circuit requirements for low-temperature operation or leakage-sensitive designs.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® are different supply formats for the same component. Tape & Reel is a continuous reel format suitable for high-volume automated assembly. Cut Tape is a sectioned format for lower-volume or mixed-component orders. Digi-Reel® is a proprietary packaging format. All formats contain identical components in the same DO-214AA (SMB) package and are mechanically interchangeable on PCBs.

Q: Does the SS23 from Taiwan Semiconductor Corporation have different electrical performance than the Vishay SS23-M3/5BT?

A: No. The Taiwan Semiconductor Corporation SS23 is a parametric equivalent with identical electrical specifications (30 V, 2 A, 500 mV forward voltage, 400 µA reverse leakage). The only differences are the minimum junction temperature (-55°C versus -65°C) and packaging format (Tape & Reel). For applications operating above -55°C, this part is fully compatible.

Q: Which substitute part has the lowest forward voltage drop?

A: B130LB-13-F has the lowest forward voltage at 445 mV @ 2 A, compared to 500 mV @ 2 A for all other listed parts. This lower forward voltage results in reduced power dissipation in applications with continuous 2 A current flow.

Q: Are there any temperature limitations I should consider when selecting a substitute?

A: Yes. The SS23-M3/5BT and SS23-E3/52T support a minimum junction temperature of -65°C, while B130LB-13-F, MBRS230LT3G, and SS23 support only -55°C minimum. For applications requiring operation below -55°C, use SS23-M3/5BT, SS23-E3/52T, or B230-13-F. B230-13-F offers the highest maximum junction temperature at 150°C, suitable for high-temperature environments.
