Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4SMA220A-M3/61 are qualified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 185V
• Voltage - Breakdown (Min): 209V
• Voltage - Clamping (Max) @ Ipp: 328V
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)

The P4SMA220A manufactured by Eaton - Electronics Division meets these core substitution criteria. Both devices share identical voltage specifications and package configuration, enabling direct functional replacement in surface mount applications requiring 185V standoff protection with 328V clamping characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the P4SMA220A-M3/61 (Vishay) and P4SMA220A (Eaton) are Active product status components with full RoHS compliance and unlimited moisture sensitivity ratings. The Eaton variant demonstrates higher peak pulse current capability (1.3A versus 900mA) and greater peak pulse power (400W versus 300W), providing additional margin in transient suppression applications. The Eaton device operates across a slightly narrower temperature range (-55°C to 150°C versus -65°C to 150°C). Both devices maintain identical voltage protection characteristics and package configuration, supporting direct substitution in surface mount TVS diode applications.

Frequently Asked Questions (FAQ)

Q: Can the P4SMA220A (Eaton) directly replace the P4SMA220A-M3/61 (Vishay)?

A: Yes. Both devices share identical reverse standoff voltage (185V), breakdown voltage (209V minimum), clamping voltage (328V maximum), and DO-214AC SMA package configuration. The Eaton variant offers higher current and power ratings, making it suitable for equivalent or higher-performance applications.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer source and performance headroom. The Eaton P4SMA220A provides 1.3A peak pulse current and 400W peak pulse power compared to the Vishay device's 900mA and 300W. The Vishay device supports a lower operating temperature minimum (-65°C versus -55°C). Voltage protection characteristics remain identical.

Q: Are package dimensions identical between these parts?

A: Both devices use the DO-214AC (SMA) surface mount package, ensuring mechanical and electrical compatibility in PCB layouts designed for either component.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. The P4SMA220A-M3/61 is RoHS3 compliant, and the P4SMA220A (Eaton) is RoHS compliant. Both meet environmental and regulatory standards for electronics manufacturing.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For applications requiring operation below -55°C, the Vishay P4SMA220A-M3/61 is necessary. For standard applications within -55°C to 150°C range, either part is acceptable. The Eaton variant provides additional transient suppression margin with higher current and power ratings.
