Substitute Part Grouping Explanation

Substitution eligibility for the DST3080C is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 80 V
• Current - Average Rectified (Io) per Diode: 15 A
• Voltage - Forward (Vf) (Max) @ If: 820 mV @ 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 700 µA @ 80 V
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Non-Negotiable):

• Mounting Type: Through Hole
• Package / Case: TO-220-3

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

Engineering Selection Recommendations

The DST3080C maintains Active product status with full regulatory compliance under RoHS3 and REACH unaffected designations. The component is available in production quantities (652 Pcs New Original In Stock) with unlimited moisture sensitivity tolerance, supporting direct integration into manufacturing workflows without additional handling protocols.

Selection of the DST3080C as a Schottky diode array for 80 V / 15 A rectification applications is supported by its fast recovery characteristics (≤ 500ns), low forward voltage drop (820 mV @ 15 A), and wide operating temperature range (-55°C to 150°C). The TO-220-3 through-hole package provides standard thermal management and mechanical mounting compatibility with conventional PCB assembly processes.

No alternative substitute parts are identified within the provided dataset that meet the complete parameter specification for this component category.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the DST3080C?

A: A valid substitute must match all electrical parameters (80 V reverse voltage, 15 A average rectified current, 820 mV forward voltage @ 15 A, fast recovery ≤ 500ns, 700 µA reverse leakage @ 80 V), maintain the 1 Pair Common Cathode configuration, operate across -55°C to 150°C, use Schottky technology, and be packaged in TO-220-3 through-hole format with ROHS3 compliance.

Q: Can the DST3080C be replaced with a different diode array configuration?

A: No. The 1 Pair Common Cathode configuration is a specific electrical topology. Substitution with different configurations (such as dual independent diodes or alternative common arrangements) would alter circuit behavior and is not permitted.

Q: Is the TO-220-3 package interchangeable with other TO-220 variants?

A: No. The TO-220-3 designation specifies a three-lead through-hole package. Other TO-220 variants (such as TO-220-2 or surface-mount alternatives) have different pin counts and mounting characteristics and are not compatible.

Q: What is the significance of the 820 mV forward voltage specification?

A: The forward voltage drop at 15 A operating current directly affects power dissipation and circuit efficiency. This parameter must be matched exactly in substitute components to ensure equivalent thermal performance and circuit behavior.

Q: Does RoHS3 compliance affect substitute selection?

A: Yes. All substitute components must maintain ROHS3 Compliant status to meet regulatory requirements in target markets. Non-compliant alternatives cannot be used as direct substitutes.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management.
