P6SMB36CAHM3_A/I Equivalent & Substitute Parts

Part Overview

The P6SMB36CAHM3_A/I is a bidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is designed for telecom applications requiring transient overvoltage protection with a 30.8V reverse standoff voltage and 49.9V maximum clamping voltage. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB36CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 30.8V
• Voltage - Breakdown (Min): 34.2V
• Voltage - Clamping (Max) @ Ipp: 49.9V
• Current - Peak Pulse (10/1000µs): 12A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Bidirectional Channels: 1
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The P6SMB36CAHM3_B/I is classified as a manufacturer-recommended substitute. This part maintains identical electrical performance specifications and mechanical packaging while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB36CAHM3_B/I is the direct equivalent for the obsolete P6SMB36CAHM3_A/I. Both parts are manufactured by Vishay and maintain identical electrical and thermal specifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support. Both parts satisfy automotive-grade requirements with AEC-Q101 qualification and ROHS3 compliance, making them suitable for regulated applications. The primary distinction is packaging format: the substitute is supplied in Tape & Reel configuration, which is standard for high-volume production environments. Selection between these parts should be based on procurement requirements and supply chain availability rather than technical performance, as electrical and mechanical compatibility is complete.

Frequently Asked Questions (FAQ)

Q: Can P6SMB36CAHM3_B/I be used as a direct replacement for P6SMB36CAHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical. The substitute maintains the same voltage ratings (30.8V standoff, 49.9V clamping), current handling (12A peak pulse), power dissipation (600W), and DO-214AA SMB package. Automotive qualification and AEC-Q101 certification are identical.

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

A: The primary differences are product status and packaging format. The P6SMB36CAHM3_A/I is classified as obsolete, while the P6SMB36CAHM3_B/I is active. The substitute is supplied in Tape & Reel packaging, which is standard for production assembly. All electrical and thermal specifications are identical.

Q: Are there any compatibility concerns when substituting?

A: No compatibility concerns exist. Both parts use the identical DO-214AA SMB surface mount package, operate across the same temperature range (-65°C to 150°C), and provide identical transient suppression performance. PCB layout and assembly processes require no modification.

Q: Does the Tape & Reel packaging affect performance?

A: No. Tape & Reel is a packaging and delivery format only. It does not affect component performance, electrical characteristics, or reliability. This format is standard for automated assembly operations.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry automotive grade classification and AEC-Q101 qualification, meeting automotive industry standards for reliability and quality.
