P6SMB100AHE3_A/I Equivalent & Substitute Parts

Part Overview

The P6SMB100AHE3_A/I is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the P6SMB TransZorb® series. This component is designed for surface mount applications in DO-214AA (SMB) packaging and provides transient voltage protection with a 100V reverse standoff voltage and 137V maximum clamping voltage. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the P6SMB100AHE3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 85.5V
• Voltage - Breakdown (Min): 95V
• Voltage - Clamping (Max) @ Ipp: 137V
• Current - Peak Pulse (10/1000µs): 4.4A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Unidirectional Channels: 1
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The P6SMB100AHE3_B/I is the manufacturer-recommended substitute, maintaining identical electrical specifications and automotive-grade qualification while differing only in packaging format (Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB100AHE3_B/I is the direct equivalent substitute for the obsolete P6SMB100AHE3_A/I. Both parts maintain identical electrical performance specifications and automotive-grade AEC-Q101 qualification. The primary distinction is product status: the substitute is currently in active production, ensuring long-term availability and supply chain continuity.

Selection of the P6SMB100AHE3_B/I is appropriate for all applications previously using the P6SMB100AHE3_A/I without circuit redesign or re-qualification, provided that the Tape & Reel packaging format is compatible with your assembly process.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB100AHE3_B/I be used as a direct replacement for the P6SMB100AHE3_A/I?

A: Yes. Both parts are electrically identical with matching voltage ratings (85.5V reverse standoff, 137V clamping), current ratings (4.4A peak pulse), power dissipation (600W), and operating temperature range (-65°C to 150°C). Both carry automotive-grade AEC-Q101 qualification and ROHS3 compliance.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The P6SMB100AHE3_A/I uses standard packaging, while the P6SMB100AHE3_B/I is supplied in Tape & Reel (TR) format. Additionally, the substitute is in active production status, whereas the main part is obsolete.

Q: Are there any compatibility concerns with the Tape & Reel packaging?

A: No compatibility concerns exist at the component level. The Tape & Reel format is a standard supply method for surface mount components and is compatible with automated assembly equipment. Verify that your assembly process supports Tape & Reel component feeding.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the P6SMB100AHE3_A/I and P6SMB100AHE3_B/I are automotive-grade components with AEC-Q101 qualification, suitable for automotive applications requiring transient voltage suppression.

Q: What electrical parameters determine substitution eligibility?

A: Substitution is determined by matching reverse standoff voltage (85.5V), breakdown voltage (95V minimum), clamping voltage (137V maximum), peak pulse current (4.4A), peak pulse power (600W), and operating temperature range (-65°C to 150°C). All these parameters are identical between the main part and substitute.
