P6SMB16A-M3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB16A-M3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates as a Zener-type TVS device in the P6SMB series, designated as TransZorb®. The part is actively produced and widely used in general-purpose transient voltage suppression applications. Finding equivalent and substitute parts becomes necessary due to supply chain variations, packaging preferences, or manufacturer availability while maintaining identical electrical performance and mechanical compatibility.

• Voltage - Clamping (Max) @ Ipp: 22.5V
• Current - Peak Pulse (10/1000µs): 26.7A minimum
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: DO-214AA, SMB

Allowed Variations:

• Packaging format (Tape & Box vs. Tape & Reel)
• Manufacturer (same electrical/mechanical specifications)
• Operating temperature range (if equal or wider)
• RoHS compliance status (if equal or higher standard)

Parameter Comparison

Engineering Selection Recommendations

P6SMB16A-E3/5B (Vishay General Semiconductor - Diodes Division): This part is a direct electrical and mechanical equivalent to the P6SMB16A-M3/52. The only difference is the packaging format (Tape & Reel instead of Tape & Box). Both parts are ROHS3 compliant, actively produced, and maintain identical electrical specifications. Selection of this part is appropriate when Tape & Reel packaging is preferred for automated assembly processes.

P6SMB16A (Eaton - Electronics Division): This part meets all critical electrical and mechanical requirements with a marginally higher peak pulse current specification (27.1A vs. 26.7A), which provides additional performance margin. The operating temperature range is narrower (-55°C to 150°C vs. -65°C to 150°C), which may be a consideration for applications requiring extended low-temperature operation below -55°C. This part is RoHS compliant and actively produced. Selection is appropriate when Eaton sourcing is preferred or when the higher current rating provides system-level benefits.

Frequently Asked Questions (FAQ)

Q: Can P6SMB16A-E3/5B be used as a direct replacement for P6SMB16A-M3/52? A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications (13.6V standoff, 22.5V clamping, 26.7A peak pulse current, 600W peak power). The difference is packaging format only (Tape & Box vs. Tape & Reel). Electrical performance and mechanical fit are equivalent.

Q: What is the difference between the Vishay and Eaton versions? A: The Eaton P6SMB16A has a slightly higher peak pulse current rating (27.1A vs. 26.7A) and a narrower operating temperature range (-55°C to 150°C vs. -65°C to 150°C). All other electrical parameters and the DO-214AA SMB package are identical. The Eaton part is suitable for applications not requiring operation below -55°C.

Q: Are all three parts pin-compatible? A: Yes. All three parts use the DO-214AA (SMB) surface mount package with identical pinout and footprint. They are mechanically interchangeable on PCBs designed for this package.

Q: Does packaging format affect electrical performance? A: No. Tape & Box and Tape & Reel packaging formats contain the same component and do not affect electrical characteristics. The choice between formats depends on assembly process requirements and inventory management preferences.

Q: Which part should I select for new designs? A: For new designs, either the Vishay P6SMB16A-E3/5B or Eaton P6SMB16A are appropriate. Selection should be based on preferred manufacturer, packaging format availability, and whether the operating temperature range of -55°C to 150°C (Eaton) is sufficient for your application. If operation below -55°C is required, use the Vishay part with the -65°C lower limit.

Q: Are all parts RoHS compliant? A: Yes. The Vishay parts are ROHS3 compliant, and the Eaton part is RoHS compliant. Both standards meet current environmental regulations.
