P6SMB170A-M3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB170A-M3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, classified as a Zener-type device in the P6SMB TransZorb® series. This surface mount component operates in the DO-214AA (SMB) package and is designed for general purpose transient voltage suppression applications. The part is currently active in production with 778 pieces available in new original stock. Equivalent and substitute parts are necessary to address supply chain variations, packaging preferences, and manufacturer availability while maintaining identical electrical performance and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the P6SMB170A-M3/5B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 145V
• Voltage - Breakdown (Min): 162V
• Voltage - Clamping (Max) @ Ipp: 234V
• Current - Peak Pulse (10/1000µs): 2.6A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA or SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -65°C to 150°C (TJ) or compatible range
• RoHS Compliance: ROHS3 or equivalent

All identified substitute parts maintain identical electrical specifications across voltage, current, and power ratings. Packaging variations (Tape & Box vs. Tape & Reel) and manufacturer differences do not affect electrical performance or mechanical fit. Substitute parts are grouped by direct manufacturer equivalence and manufacturer-recommended alternatives.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the P6SMB170A-M3/5B. Selection among equivalents should be based on the following factors:

P6SMB170A-E3/52 (Vishay): Direct manufacturer equivalent with identical specifications. Differs only in packaging format (Tape & Reel vs. Tape & Box). Recommended for high-volume procurement due to superior inventory availability (12,400 pieces).

SMBJP6KE170A-TP (Micro Commercial Co): Alternative manufacturer source with identical electrical specifications and operating temperature range. Maintains ROHS3 compliance and MSL 1 rating. Suitable for supply chain diversification.

P6SMB170A (Eaton): Manufacturer-recommended alternative with identical electrical performance. Operating temperature range extends to -55°C minimum (vs. -65°C for Vishay variants), which remains within acceptable limits for most applications. Highest inventory availability (41,300 pieces) supports extended lead time requirements. RoHS compliant per Eaton specifications.

All parts are active products with established production status and full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can P6SMB170A-E3/52 be used as a direct replacement for P6SMB170A-M3/5B?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications (145V standoff, 162V breakdown, 234V clamping, 2.6A peak pulse, 600W peak power). The only difference is packaging format: Tape & Reel (E3/52) versus Tape & Box (M3/5B). Electrical performance and mechanical fit are equivalent.

Q: What is the difference between SMBJP6KE170A-TP and the Vishay variants?

A: SMBJP6KE170A-TP is manufactured by Micro Commercial Co rather than Vishay. All electrical parameters are identical: 145V standoff, 162V breakdown, 234V clamping, 2.6A peak pulse, and 600W peak power. Operating temperature range, RoHS compliance, and MSL rating are equivalent. The part number format differs due to manufacturer nomenclature conventions.

Q: Is the Eaton P6SMB170A compatible with the original P6SMB170A-M3/5B?

A: Yes. The Eaton part maintains all critical electrical specifications and operates across -55°C to 150°C (versus -65°C to 150°C for Vishay). This narrower low-temperature range does not affect compatibility for most applications. Package, mounting type, and regulatory compliance are equivalent.

Q: Does packaging format (Tape & Box vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical specifications, performance characteristics, and mechanical fit remain identical regardless of packaging type.

Q: Are all substitute parts RoHS compliant?

A: Yes. P6SMB170A-E3/52 and SMBJP6KE170A-TP are ROHS3 compliant. P6SMB170A (Eaton) is RoHS compliant. All parts meet regulatory requirements for restricted substance elimination.

Q: Which substitute part should be selected for maximum inventory availability?

A: P6SMB170A (Eaton) offers the highest inventory level at 41,300 pieces, followed by P6SMB170A-E3/52 (Vishay) at 12,400 pieces. Both are suitable for applications requiring extended lead time assurance.
