P6SMB8.2CA-M3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB8.2CA-M3/52 is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This bidirectional zener diode is designed for general-purpose transient voltage suppression in surface-mount applications. The device features a 7.02V reverse standoff voltage and 12.1V maximum clamping voltage, with a peak pulse current rating of 49.6A and 600W peak pulse power dissipation. The part is supplied in DO-214AA (SMB) package format on tape and reel. As an active product with ROHS3 compliance and unlimited moisture sensitivity level, equivalent alternatives are available from multiple manufacturers to support design flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB8.2CA-M3/52 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - Reverse Standoff (Typ): 7.02V ± tolerance
• Voltage - Clamping (Max) @ Ipp: 12.1V ± tolerance
• Current - Peak Pulse (10/1000µs): minimum 49.6A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener
• RoHS Status: ROHS3 Compliant

The substitute parts listed below meet these electrical specifications within acceptable engineering tolerances and maintain identical mechanical compatibility. Packaging format variations (Tape & Box vs. Cut Tape vs. Tape & Reel) do not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), consistent with the primary part specification. Selection among these alternatives should be based on:

Inventory and Supply Availability: The P6SMB8.2CA from Taiwan Semiconductor Corporation offers the highest inventory level (4,113 pcs) and represents the manufacturer-recommended substitute. SMBJ7V0CA from Taiwan Semiconductor Corporation provides the largest available stock (27,018 pcs) among all alternatives.

Electrical Performance: The P6SMB8.2CA-E3/52 (Vishay, Cut Tape format) provides identical electrical specifications to the primary part. The SMBJ series alternatives (SMBJ7.0CA, SMBJ7.0CA-13-F, SMBJ7.0CA-TP, SMBJ7V0CA) operate within the same functional envelope with minor voltage and current variations within acceptable engineering tolerances.

Temperature Operating Range: The SMBJ7.0CA-TP variant extends the upper operating temperature to 175°C, compared to 150°C for the primary part and most alternatives. The P6SMB8.2CA from Taiwan Semiconductor Corporation has a lower minimum operating temperature (-55°C vs. -65°C).

Packaging Format: All parts are supplied in DO-214AA (SMB) surface-mount package. Packaging format differences (Tape & Box, Cut Tape, Tape & Reel) do not affect electrical or mechanical compatibility and should be selected based on assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute P6SMB8.2CA-E3/52 for P6SMB8.2CA-M3/52?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications (7.02V Vwm, 12.1V Vc, 49.6A Ipp, 600W Ppp). The difference is packaging format: M3/52 is Tape & Box, while E3/52 is Cut Tape. Electrical and mechanical compatibility is maintained.

Q: Are SMBJ7.0CA series parts fully compatible with P6SMB8.2CA-M3/52?

A: SMBJ7.0CA series parts (SMBJ7.0CA, SMBJ7.0CA-13-F, SMBJ7.0CA-TP, SMBJ7V0CA) operate within the same functional specification envelope. Voltage ratings are 7.0V Vwm and 12V Vc compared to 7.02V and 12.1V respectively. Peak pulse current is 50A versus 49.6A. These minor variations fall within acceptable engineering tolerances for general-purpose transient voltage suppression applications. All maintain identical 600W peak pulse power rating and DO-214AA (SMB) package format.

Q: What is the difference between P6SMB8.2CA from Taiwan Semiconductor Corporation and the Vishay P6SMB8.2CA-M3/52?

A: Both share the same base part number P6SMB8.2 and identical electrical specifications. The Taiwan Semiconductor Corporation version is supplied in Tape & Reel format with 52A peak pulse current (versus 49.6A) and operates over -55°C to 150°C (versus -65°C to 150°C). Electrical performance is equivalent within standard tolerances.

Q: Does packaging format affect substitutability?

A: No. Tape & Box (TB), Cut Tape (CT), and Tape & Reel (TR) packaging formats are logistics variations only. All formats contain the same component in DO-214AA (SMB) package. Selection should be based on assembly process requirements and inventory management, not electrical compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and MSL 1 (Unlimited) moisture sensitivity level, matching the primary part specification.

Q: Which substitute part has the highest inventory availability?

A: SMBJ7V0CA from Taiwan Semiconductor Corporation has the largest stock level at 27,018 pcs. P6SMB8.2CA from Taiwan Semiconductor Corporation offers 4,113 pcs as the manufacturer-recommended alternative.
