P6SMBJ30A Equivalent & Substitute Parts
Part Overview
The P6SMBJ30A is an active Transient Voltage Suppressor (TVS) diode manufactured by Diotec Semiconductor. This unidirectional zener TVS device is designed for general-purpose transient voltage suppression applications and is supplied in surface mount packaging. The device operates across an industrial temperature range and is available in high inventory quantities. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate alternative package configurations or manufacturer qualifications.

Substitute Part Grouping Explanation
Substitute parts for the P6SMBJ30A are identified based on electrical parameter equivalence and functional compatibility. The critical parameters determining substitution eligibility are:
- Voltage - Reverse Standoff (Typ): 30V
- Voltage - Clamping (Max) @ Ipp: 48.4V
- Current - Peak Pulse (10/1000µs): 12.4A
- Power - Peak Pulse: 600W
- Type: Zener, Unidirectional
- Mounting Type: Surface Mount
The PTVS30VP1UP,115 manufactured by Nexperia USA Inc. meets all electrical parameter requirements for substitution. While the package configuration differs (SOD-128 versus DO-214AA), both are surface mount packages suitable for equivalent circuit board integration. The substitute part maintains identical electrical performance specifications and is qualified to automotive standards (AEC-Q101), providing enhanced reliability documentation.

Engineering Selection Recommendations
Both the P6SMBJ30A and PTVS30VP1UP,115 are active products with identical electrical performance specifications. Selection between these parts is determined by application-specific requirements:
P6SMBJ30A Selection Criteria:
- Applications requiring DO-214AA (SMB) package footprint
- Designs with existing PCB layouts specified for SMB packages
- General industrial applications without automotive qualification requirements
PTVS30VP1UP,115 Selection Criteria:
- Applications requiring SOD-128 package footprint
- Designs requiring AEC-Q101 automotive qualification
- Applications requiring ROHS3 compliance documentation
- Designs with existing PCB layouts specified for SOD-128 packages
- Extended lower operating temperature limit (-55°C versus -50°C)
Both parts are supplied in Tape & Reel packaging and maintain equivalent electrical performance across the specified operating temperature ranges.
Frequently Asked Questions (FAQ)
Q: Can PTVS30VP1UP,115 be used as a direct replacement for P6SMBJ30A?
A: Electrical substitution is valid. The parts are electrically equivalent with identical voltage and current ratings. However, the package footprint differs (SOD-128 versus DO-214AA), requiring PCB layout modification. Verify footprint compatibility with your circuit board design before implementation.
Q: What is the primary difference between these two TVS diodes?
A: The primary differences are package configuration and manufacturer qualifications. The P6SMBJ30A uses DO-214AA (SMB) packaging, while the PTVS30VP1UP,115 uses SOD-128 packaging. The Nexperia part includes AEC-Q101 automotive qualification and ROHS3 compliance certification.
Q: Are there temperature range differences between these parts?
A: The operating temperature ranges differ slightly. The P6SMBJ30A operates from -50°C to 150°C (junction temperature), while the PTVS30VP1UP,115 operates from -55°C to 150°C (ambient temperature). The Nexperia part provides a lower minimum temperature specification.
Q: Which part should be selected for automotive applications?
A: The PTVS30VP1UP,115 is qualified to AEC-Q101 automotive standards and is the appropriate selection for automotive applications requiring documented qualification.
Q: Do both parts require the same PCB footprint?
A: No. The P6SMBJ30A requires a DO-214AA (SMB) footprint, while the PTVS30VP1UP,115 requires a SOD-128 footprint. PCB layout modifications are necessary when substituting between these parts.
Q: Are both parts currently available?
A: Yes. The P6SMBJ30A has 3,397 pieces in stock, and the PTVS30VP1UP,115 has 2,000 pieces in stock as new original inventory.
