Substitute Part Grouping Explanation

Substitution of the SS13H is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

Voltage - DC Reverse (Vr) Maximum: 30V
Current - Average Rectified (Io): 1A
Technology: Schottky
Mounting Type: Surface Mount
Package / Case: DO-214AC (SMA) or compatible SMA footprint

Acceptable Variation Parameters:

Voltage - Forward (Vf) Maximum: Substitute parts may exhibit forward voltage between 410 mV and 500 mV at rated current without functional impact
Current - Reverse Leakage @ Vr: Substitute parts may range from 200 µA to 1 mA at 30V without affecting primary rectification function
Operating Temperature - Junction: Substitute parts with extended temperature ranges (-65°C to 150°C) are acceptable for applications within the SS13H operating window (-55°C to 125°C)
Packaging Format: Cut Tape (CT), Digi-Reel, and Tape & Reel (TR) formats are interchangeable for the same electrical component

Non-Substitutable Parameters:

Reverse voltage rating below 30V
Average rectified current below 1A
Non-Schottky technology
Through-hole or non-surface-mount configurations
Packages other than DO-214AC/SMA or mechanically compatible alternatives

Substitute parts are grouped into three categories: parametric equivalents (identical electrical specifications, different packaging), similar parts from alternative manufacturers (equivalent ratings with minor parameter variations), and higher-current variants (suitable only when design permits increased current capacity).

Engineering Selection Recommendations

Direct Parametric Equivalent (Identical Electrical Specifications):

The SS13 R3G from Taiwan Semiconductor Corporation is a parametric equivalent to the SS13H, offering identical electrical characteristics (30V, 1A, 500 mV forward voltage, 200 µA reverse leakage) in the same DO-214AC package. However, this part is listed as Discontinued at DiGi Electronics and lacks AEC-Q101 automotive qualification. Selection of this part is appropriate only for non-automotive applications where supply chain continuity is not critical.

Primary Substitute for Automotive Applications:

The B130Q-13-F from Diodes Incorporated is the recommended substitute for automotive-grade applications. This part maintains the SS13H's 30V/1A electrical ratings, DO-214AC package compatibility, and AEC-Q101 qualification. The B130Q-13-F operates across an extended temperature range (-65°C to 150°C), which encompasses the SS13H operating window. Forward voltage and reverse leakage specifications are within acceptable variation limits.

Alternative Substitutes for Non-Automotive Applications:

The B130-13-F and B130L-13-F from Diodes Incorporated are suitable alternatives when automotive qualification is not required. Both maintain 30V/1A ratings and DO-214AC package compatibility. The B130L-13-F offers improved forward voltage characteristics (410 mV versus 500 mV), beneficial for low-power applications. Both parts are in Active product status with high inventory availability.

Package-Variant Substitutes:

The B130LAW-7-F provides equivalent electrical performance in a SOD-123 package, suitable only when PCB layout permits alternative footprint geometry. The B130B-13-F is available in DO-214AA (SMB) package format, requiring different PCB land pattern design.

Higher-Current Alternatives:

The B230AQ-13-F, B230LA-E3/5AT, and B230LA-E3/61T are rated for 2A average rectified current at 30V reverse voltage. These parts are suitable substitutes only when circuit design permits increased current capacity and when the larger current rating does not introduce thermal or reliability concerns. All three maintain DO-214AC package compatibility with the SS13H.

Compliance and Certification Considerations:

For applications requiring AEC-Q101 automotive qualification, selection is limited to SS13H (Active), SS13 R3G (Discontinued), B130Q-13-F (Active), B230AQ-13-F (Active), and B230LA-E3/5AT and B230LA-E3/61T (non-qualified). The B130Q-13-F is the only actively available automotive-qualified alternative in the 1A current class with identical package format.

Frequently Asked Questions (FAQ)

Q: Can the B130-13-F directly replace the SS13H in automotive applications?

A: The B130-13-F is electrically compatible with the SS13H (30V, 1A, DO-214AC package) but lacks AEC-Q101 automotive qualification. Use of this part in automotive applications requires design review and customer approval. For automotive applications, the B130Q-13-F is the qualified alternative.

Q: What is the difference between the B130L-13-F and B130-13-F?

A: Both parts are rated 30V/1A in DO-214AC packages. The B130L-13-F exhibits lower forward voltage (410 mV versus 500 mV at 1A) and higher reverse leakage (1 mA versus 500 µA at 30V). The B130L-13-F is suitable for applications where reduced forward voltage drop is beneficial for efficiency.

Q: Can the B230AQ-13-F be used as a substitute for the SS13H?

A: The B230AQ-13-F is electrically compatible at the 30V reverse voltage rating and maintains DO-214AC package compatibility. However, this part is rated for 2A average rectified current, double the SS13H rating. Substitution is acceptable only when circuit design permits the higher current capacity and when thermal considerations do not introduce reliability concerns. The B230AQ-13-F carries AEC-Q101 qualification, making it suitable for automotive applications.

Q: What is the significance of the packaging format differences (Tape & Reel versus Cut Tape)?

A: Tape & Reel (TR) and Cut Tape (CT) formats contain identical electrical components but differ in supply format. Tape & Reel is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape is supplied in shorter tape segments. Selection between formats depends on manufacturing process requirements and inventory management practices. Electrical performance is identical.

Q: Why does the SS13 R3G show as Discontinued at DiGi Electronics?

A: The SS13 R3G is a parametric equivalent to the SS13H from the same manufacturer but is no longer actively stocked by DiGi Electronics. This part remains available from other distributors but may have limited supply. For new designs, the B130Q-13-F is recommended as the primary alternative.

Q: Is the B130LAW-7-F compatible with the SS13H PCB layout?

A: The B130LAW-7-F uses a SOD-123 package, which has a different footprint than the SS13H's DO-214AC (SMA) package. Direct PCB substitution is not possible without redesigning the land pattern. The B130LAW-7-F is suitable only when PCB layout can accommodate the alternative package geometry.

Q: What does AEC-Q101 qualification mean for diode selection?

A: AEC-Q101 is an automotive electronics qualification standard that certifies components for reliability in automotive environments. Parts carrying AEC-Q101 qualification have undergone stress testing and reliability validation. For automotive applications, AEC-Q101 qualified parts are required. The SS13H and B130Q-13-F both carry this qualification.

Q: Can I use the B230LA-E3/5AT or B230LA-E3/61T in place of the SS13H?

A: These Vishay parts are rated for 2A average rectified current at 30V and maintain DO-214AC package compatibility. Electrical substitution is acceptable only when circuit design permits the higher current rating. These parts lack AEC-Q101 qualification and are suitable for non-automotive applications.

Q: What is the difference between B230LA-E3/5AT and B230LA-E3/61T?

A: Both parts are electrically identical 30V/2A Schottky diodes in DO-214AC packages from Vishay. The designation suffix indicates different tape reel configurations or manufacturing date codes. Electrical performance and package compatibility are identical.

Q: How do I determine which substitute part is best for my application?

A: Selection depends on three primary criteria: (1) Automotive qualification requirement—use B130Q-13-F for AEC-Q101 applications; (2) Current rating—use 1A-rated parts (SS13H, B130Q-13-F, B130-13-F, B130L-13-F) for standard applications or 2A-rated parts (B230 series) only when circuit design permits; (3) Package format—confirm PCB footprint compatibility before selection. All recommended substitutes maintain 30V reverse voltage rating and Schottky technology.
