Engineering Selection Recommendations

Tier 1 - Direct Parametric Equivalents (Recommended for Direct Replacement):

SSL13H from Taiwan Semiconductor Corporation is the primary recommended substitute. This part maintains identical electrical specifications to the SSL13HR3G (30V, 1A, 390mV forward voltage, 200µA reverse leakage) and operates across the same junction temperature range (-55°C to 125°C). SSL13H carries AEC-Q101 automotive qualification, matching the original part's certification status. This part is currently in active production with 1028 units in stock.

SSL13 from Taiwan Semiconductor Corporation is an alternative parametric equivalent with identical electrical characteristics. This part differs only in automotive qualification status (not AEC-Q101 qualified) and is available in higher inventory (7700 units). Selection of SSL13 is appropriate for non-automotive applications or where automotive qualification is not required.

Tier 2 - Compatible Substitutes with Minor Parameter Variations:

B130L-13-F from Diodes Incorporated meets the core voltage and current requirements (30V, 1A) with compatible package (DO-214AC, SMA). Forward voltage is 410mV at 1A, which is 20mV higher than the SSL13HR3G. Reverse leakage current is 1mA at 30V, which is higher than the original 200µA specification. Operating temperature range matches the original (-55°C to 125°C). This part is in active production with 210200 units in stock.

B130-E3/5AT and B130-E3/61T from Vishay General Semiconductor both meet voltage and current specifications (30V, 1A) in DO-214AC, SMA package. Forward voltage is 520mV at 1A, which is 130mV higher than the SSL13HR3G. Reverse leakage current matches at 200µA at 30V. Operating temperature range extends to -65°C minimum. Both parts are in active production.

B130Q-13-F from Diodes Incorporated is an automotive-qualified alternative (AEC-Q101) with 30V, 1A specifications in DO-214AC, SMA package. Forward voltage is 500mV at 1A and reverse leakage is 500µA at 30V. Operating temperature range extends to -65°C to 150°C. This part is in active production with 10200 units in stock and is suitable for automotive applications requiring AEC-Q101 qualification.

Tier 3 - Alternative Package Configurations:

B130LAW-7-F from Diodes Incorporated provides 30V, 1A Schottky rectification in SOD-123 package. This part is suitable only when PCB layout permits SOD-123 package substitution for DO-214AC, SMA. Forward voltage is 420mV at 1A and reverse leakage is 1mA at 30V.

B130B-13-F and B130LB-13-F from Diodes Incorporated use SMB package (DO-214AA) instead of SMA. B130B-13-F maintains 1A current rating while B130LB-13-F increases to 2A. These parts are suitable only when SMB package footprint is available on the PCB.

Frequently Asked Questions (FAQ)

Q: Can SSL13 be used as a direct replacement for SSL13HR3G?

A: SSL13 is electrically equivalent to SSL13HR3G with identical voltage (30V), current (1A), forward voltage (390mV @ 1A), and reverse leakage (200µA @ 30V) specifications. The primary difference is that SSL13 is not AEC-Q101 automotive qualified. For non-automotive applications, SSL13 is a direct replacement. For automotive applications requiring AEC-Q101 qualification, SSL13H is the appropriate choice.

Q: What is the difference between SSL13H and SSL13HR3G?

A: SSL13H and SSL13HR3G are electrically identical with matching voltage, current, forward voltage, and reverse leakage specifications. Both operate across -55°C to 125°C and are AEC-Q101 qualified. The primary difference is product status: SSL13HR3G is discontinued while SSL13H is in active production. SSL13H is the direct replacement for SSL13HR3G.

Q: Can B130-13-F replace SSL13HR3G?

A: B130-13-F meets the core voltage (30V) and current (1A) requirements and uses the same DO-214AC, SMA package. However, forward voltage is 500mV at 1A compared to 390mV for SSL13HR3G, representing a 110mV increase. Reverse leakage current is 500µA at 30V compared to 200µA for SSL13HR3G. Operating temperature range extends to -65°C to 150°C. B130-13-F is suitable for applications where the higher forward voltage and reverse leakage are acceptable.

Q: Is B130Q-13-F suitable for automotive applications?

A: Yes. B130Q-13-F is AEC-Q101 qualified and meets automotive standards. It provides 30V, 1A Schottky rectification in DO-214AC, SMA package. Forward voltage is 500mV at 1A and operating temperature range is -65°C to 150°C. B130Q-13-F is appropriate for automotive applications where AEC-Q101 qualification is required.

Q: What package compatibility must be verified when selecting a substitute?

A: The SSL13HR3G uses DO-214AC, SMA package. Direct substitutes must use the same DO-214AC, SMA package to ensure PCB footprint compatibility. Parts such as B130LAW-7-F (SOD-123) and B130B-13-F (DO-214AA, SMB) use different packages and require PCB layout verification before selection. Package mismatch will result in assembly incompatibility.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage (Vf) determines the voltage drop across the diode during conduction. SSL13HR3G specifies 390mV at 1A. Substitute parts with higher forward voltage (such as B130-13-F at 500mV or B130-E3/5AT at 520mV) will produce greater voltage drops and increased power dissipation. Circuit designs with tight voltage margin requirements must account for these differences. Designs with adequate voltage headroom can tolerate higher forward voltage specifications.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current (Ir) represents the small current flowing through the diode when reverse biased. SSL13HR3G specifies 200µA at 30V. Parts with higher reverse leakage (such as B130-13-F at 500µA or B130L-13-F at 1mA) will exhibit greater leakage current in reverse bias conditions. For applications sensitive to leakage current (such as precision analog circuits or high-impedance circuits), lower leakage specifications are preferred. For power rectification applications, leakage current differences are typically not critical.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant and REACH unaffected, matching the environmental compliance status of SSL13HR3G.

Q: What inventory considerations apply to substitute selection?

A: SSL13H has 1028 units in stock, SSL13 has 7700 units, and B130L-13-F has 210200 units in stock. Inventory availability may influence substitute selection for high-volume production requirements. Verify current inventory status with the component supplier before finalizing procurement decisions.
