Substitute Part Grouping Explanation

Substitution of the SDB13HS-AQ is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 470 mV @ 1 A
• Current - Reverse Leakage @ Vr: 200 µA @ 30 V
• Capacitance @ Vr, F: 30 pF @ 10 V, 1 MHz

Physical and Mechanical Specifications:

• Technology: Schottky
• Package / Case: SC-76, SOD-323
• Mounting Type: Surface Mount
• Operating Temperature - Junction: −40°C to 125°C

Performance Characteristics:

• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Substitute parts must match all parameters listed above to ensure functional and mechanical compatibility within the original design. Parts that deviate from any of these specifications are not considered equivalent substitutes.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the SDB13HS-AQ?

A: A valid substitute must match all electrical specifications (30 V reverse voltage, 1 A average rectified current, 470 mV forward voltage at 1 A, 200 µA reverse leakage at 30 V, 30 pF capacitance), physical package (SOD-323), mounting type (surface mount), technology (Schottky), and performance characteristics (fast recovery ≤ 500 ns at > 200 mA).

Q: Can the SDB13HS-AQ be replaced with a different package variant?

A: No. The SOD-323 package is a critical specification for PCB layout and assembly compatibility. Substitutes must use the identical SC-76, SOD-323 package designation.

Q: Is the SDB13HS-AQ suitable for applications requiring reverse voltage protection?

A: The 30 V maximum reverse voltage rating establishes the maximum voltage the diode can withstand in reverse bias. Applications must ensure reverse voltage does not exceed this specification.

Q: What is the significance of the 470 mV forward voltage specification?

A: The forward voltage of 470 mV at 1 A defines the voltage drop across the diode during forward conduction. This parameter is critical for power dissipation calculations and circuit design.

Q: Does the fast recovery characteristic affect circuit performance?

A: Yes. The fast recovery specification (≤ 500 ns at > 200 mA) indicates the diode's switching speed, which is essential for high-frequency rectification and switching applications. Slower recovery diodes may introduce switching losses and electromagnetic interference.

Q: Are there compliance or certification considerations for this component?

A: The SDB13HS-AQ is an Active product with Active status. RoHS Status is listed as Not Applicable, and REACH Status is Vendor Undefined. Compliance requirements must be verified against specific application and regional regulations.
