Engineering Selection Recommendations
Primary Substitutes (Identical Electrical Specifications, DO-214AA/SMB Package):
SMBJ5.0A-13-F (Diodes Incorporated) is the direct replacement with identical electrical performance and ROHS3 compliance. This part maintains the same manufacturer lineage and is actively produced.
SMBJ5.0A-E3/52 (Vishay General Semiconductor - Diodes Division) provides equivalent electrical specifications with active product status and ROHS3 compliance. Vishay's TransZorb series offers established reliability in transient suppression applications.
SMBJ5.0A-TP (Micro Commercial Co) matches all electrical parameters with extended operating temperature range (-55°C ~ 175°C) and ROHS3 compliance, providing thermal margin for demanding environments.
SMBJ5.0A-TR (STMicroelectronics) delivers equivalent performance with slightly elevated peak pulse current (68A vs 65.2A) and ROHS3 compliance. STMicroelectronics' TRANSIL series is widely qualified in industrial applications.
SMBJ5.0A (EVVO Semi) provides equivalent electrical specifications with extended lower temperature range (-65°C ~ 150°C) and ROHS3 compliance.
Alternative Package Substitute:
PTVS5V0P1UP,115 (Nexperia USA Inc.) offers identical electrical specifications in SOD-128 package with AEC-Q101 automotive qualification and ROHS3 compliance. This substitute requires PCB layout modification due to different package geometry.
Limited Compatibility Substitute:
SACB5.0 (Littelfuse Inc.) maintains 5V reverse standoff voltage but differs in clamping voltage (10V vs 9.2V), peak pulse current (44A vs 65.2A), and power rating (500W vs 600W). This part is suitable only for applications with relaxed clamping voltage and current requirements.
Frequently Asked Questions (FAQ)
Q: Can SMBJ5.0A-13-F be used as a direct replacement for SMBJ5.0A-13?
A: Yes. SMBJ5.0A-13-F is electrically and mechanically identical to SMBJ5.0A-13, with the primary difference being ROHS3 compliance and active production status. Both use DO-214AA (SMB) packaging and share identical voltage and current specifications.
Q: What is the difference between DO-214AA and SMB package designations?
A: DO-214AA and SMB refer to the same physical package. DO-214AA is the JEDEC standard designation, while SMB is the industry common name. These terms are interchangeable for this product category.
Q: Why does PTVS5V0P1UP,115 have a different package (SOD-128) than the original part?
A: PTVS5V0P1UP,115 uses SOD-128 package instead of DO-214AA/SMB. While electrically equivalent, this requires PCB redesign for mechanical compatibility. Use this substitute only if PCB layout modification is feasible.
Q: Is SACB5.0 a suitable substitute for SMBJ5.0A-13?
A: SACB5.0 is not a direct substitute. While it maintains the 5V reverse standoff voltage, it differs in clamping voltage (10V vs 9.2V), peak pulse current (44A vs 65.2A), and power rating (500W vs 600W). Use SACB5.0 only for applications with relaxed performance requirements that can tolerate higher clamping voltage and lower current handling.
Q: What does ROHS3 compliance mean for this component?
A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. SMBJ5.0A-13 is RoHS non-compliant, while most active substitutes are ROHS3 compliant, making them suitable for regulated markets and modern supply chains.
Q: Can I use SMBJ5.0A-TR from STMicroelectronics if my application requires exactly 65.2A peak pulse current?
A: Yes. SMBJ5.0A-TR provides 68A peak pulse current, which exceeds the 65.2A requirement. Higher peak pulse current capability is acceptable and provides additional margin for transient suppression performance.
Q: Does operating temperature range affect substitution compatibility?
A: Operating temperature range affects compatibility only if your application requires operation outside the substitute part's specified range. SMBJ5.0A-TP (-55°C ~ 175°C) and SMBJ5.0A from EVVO Semi (-65°C ~ 150°C) offer extended temperature ranges compared to the original part (-55°C ~ 150°C), providing additional thermal margin for demanding environments.
