Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB110AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Current - Peak Pulse (10/1000µs): 3.9A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Unidirectional Channels: 1
• Type: Zener
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The P6SMB110AHM3_B/I maintains identical electrical and mechanical specifications while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging). This part is the direct functional equivalent for new designs and ongoing production requirements.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB110AHM3_B/I is the direct substitute for the obsolete P6SMB110AHM3_A/I. Both parts maintain identical electrical performance and mechanical compatibility. The primary distinction is product status: the _B/I variant is currently active and available for procurement, while the _A/I is obsolete.

Both parts carry automotive-grade qualification (AEC-Q101) and ROHS3 compliance, ensuring suitability for regulated applications. The _B/I variant is supplied in Tape & Reel packaging format, which is standard for high-volume production environments.

For new designs or production transitions, the P6SMB110AHM3_B/I should be specified. Existing designs using the _A/I variant can transition to the _B/I without circuit modification, as all electrical and thermal characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB110AHM3_B/I be used as a direct replacement for the P6SMB110AHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical. The _B/I variant is the active production equivalent of the obsolete _A/I. No circuit redesign is required.

Q: What is the difference between the _A/I and _B/I variants?

A: The primary differences are product status (Obsolete vs. Active) and packaging format (_A/I uses standard packaging; _B/I uses Tape & Reel). All electrical specifications, thermal ratings, and certifications are identical.

Q: Are both parts AEC-Q101 qualified?

A: Yes. Both the P6SMB110AHM3_A/I and P6SMB110AHM3_B/I carry AEC-Q101 automotive qualification and ROHS3 compliance.

Q: What is the operating temperature range for these parts?

A: Both parts operate across -65°C to 150°C junction temperature (TJ), suitable for automotive and telecom applications.

Q: Can these parts be used interchangeably in existing PCB layouts?

A: Yes. Both parts use the DO-214AA (SMB) surface mount package with identical pinout and footprint. No PCB modification is necessary.

Q: What is the peak pulse power rating?

A: Both parts are rated for 600W peak pulse power with a peak pulse current of 3.9A (10/1000µs waveform).
