SS32 V6G Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS32 V6G is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 20 V DC reverse voltage and 3 A average rectified current in a DO-214AB (SMC) surface mount package. This component is classified as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement needs. The part operates across a junction temperature range of -55°C to 125°C and demonstrates fast recovery characteristics suitable for high-frequency switching applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS32 V6G is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters (Critical for Substitution):

• Voltage rating: 20 V DC reverse voltage maximum
• Current rating: 3 A average rectified current
• Technology: Schottky diode classification
• Reverse leakage current: 500 µA @ 20 V
• Speed characteristics: Fast recovery ≤ 500ns, > 200mA (Io)
• Operating temperature range: -55°C to 125°C junction temperature

Mechanical Parameters (Required for Physical Compatibility):

• Mounting type: Surface mount
• Package classification: DO-214 series (includes DO-214AB and DO-214AC variants)

Compliance Parameters (Mandatory for Regulatory Acceptance):

• RoHS3 compliance status
• Moisture sensitivity level MSL 1
• REACH unaffected status

The SS32 manufactured by MDD meets all electrical and compliance requirements for direct substitution, with the primary distinction being package variant (DO-214AC/SMA versus DO-214AB/SMC) and manufacturer source.

Parameter Comparison

Engineering Selection Recommendations

The SS32 manufactured by MDD provides electrical and compliance equivalence to the discontinued SS32 V6G from Taiwan Semiconductor Corporation. Both components satisfy identical electrical specifications for voltage, current, and thermal operating ranges. Both maintain ROHS3 compliance and MSL 1 moisture sensitivity classification, supporting equivalent regulatory acceptance in production environments.

The primary distinction between these components is the package variant: the original SS32 V6G uses DO-214AB (SMC) packaging, while the MDD substitute uses DO-214AC (SMA) packaging. Both package types are DO-214 series surface mount configurations with compatible footprint dimensions and soldering characteristics for standard PCB assembly processes.

The MDD SS32 is currently in active production status with substantial inventory availability (19,566 pieces), whereas the original Taiwan Semiconductor part is discontinued. Selection of the MDD substitute eliminates supply chain discontinuity while maintaining full electrical and thermal performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the MDD SS32 directly replace the SS32 V6G in existing designs?

A: The MDD SS32 provides electrical equivalence across all critical parameters: 20 V reverse voltage rating, 3 A current capacity, fast recovery characteristics, and identical operating temperature range. The package variant difference (DO-214AC/SMA versus DO-214AB/SMC) requires PCB footprint verification, as these are distinct surface mount packages despite both belonging to the DO-214 series.

Q: What is the difference between DO-214AB (SMC) and DO-214AC (SMA) packages?

A: Both are surface mount Schottky diode packages within the DO-214 family. DO-214AB (SMC) and DO-214AC (SMA) differ in physical dimensions and land pattern geometry. PCB layout compatibility must be confirmed before substitution. Consult package datasheets for specific footprint dimensions and land pattern requirements.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Both components share identical voltage ratings (20 V), current ratings (3 A), reverse leakage specifications (500 µA @ 20 V), speed classifications (fast recovery ≤ 500ns), and operating temperature ranges (-55°C to 125°C). The MDD part provides additional capacitance specification data (500 pF @ 4V, 1MHz) not listed for the original part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SS32 V6G and MDD SS32 are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level). Regulatory acceptance is equivalent for both components.

Q: Why is the MDD SS32 preferred for new procurement?

A: The MDD SS32 is in active production status with high inventory availability, whereas the Taiwan Semiconductor SS32 V6G is discontinued. Electrical and compliance equivalence combined with active supply status makes the MDD part the appropriate selection for ongoing production requirements.

Q: Should PCB layout be modified to accommodate the package change?

A: Yes. The transition from DO-214AB (SMC) to DO-214AC (SMA) requires footprint verification and potential PCB layout modification. Consult the respective package datasheets to confirm land pattern compatibility with existing PCB designs before implementation.
