Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA190A TR13 is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff: 190V (nominal)
• Voltage - Clamping (Max) @ Ipp: 308V maximum
• Current - Peak Pulse (10/1000µs): 1.3A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA (surface mount)
• Unidirectional Channels: 1
• Operating Temperature Range: -55°C to 150°C

The TV04A191J-G from Comchip Technology meets all specified electrical parameters within acceptable tolerances and maintains identical mechanical compatibility through the DO-214AC (SMA) package specification.

Parameter Comparison

Engineering Selection Recommendations

The TV04A191J-G is the designated manufacturer-recommended substitute for the obsolete P4SMA190A TR13. This component maintains electrical parameter equivalence with negligible variance in clamping voltage (307.8V vs. 308V) and breakdown voltage (211V vs. 209V), both within acceptable engineering tolerances for TVS diode applications.

The TV04A191J-G carries active product status and holds ROHS3 compliance certification, providing assurance of ongoing availability and environmental regulatory adherence. The component is supplied in Tape & Reel packaging format and maintains REACH unaffected status.

Both components are classified under ECCN EAR99 and HTSUS 8541.10.0080, with identical moisture sensitivity level (MSL 1 - Unlimited), ensuring no additional handling or storage requirements during transition.

Frequently Asked Questions (FAQ)

Q: Can the TV04A191J-G be used as a direct replacement for the P4SMA190A TR13?

A: Yes. The TV04A191J-G meets all critical electrical parameters (190V standoff, 307.8V clamping, 1.3A peak pulse) and maintains identical DO-214AC (SMA) package compatibility. The component is the manufacturer-recommended substitute.

Q: What is the difference in clamping voltage between these parts?

A: The P4SMA190A TR13 specifies 308V maximum clamping voltage, while the TV04A191J-G specifies 307.8V. This 0.2V difference is within acceptable engineering tolerance for TVS diode applications and does not affect circuit protection performance.

Q: Are there any compliance or certification differences?

A: The TV04A191J-G carries ROHS3 compliance and REACH unaffected status, providing regulatory assurance. Both components share identical ECCN and HTSUS classifications.

Q: What packaging formats are available for the TV04A191J-G?

A: The TV04A191J-G is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: Is the operating temperature range identical?

A: Yes. Both components operate across -55°C to 150°C (TJ), ensuring thermal performance equivalence across all specified operating conditions.
