P3206UATP Equivalent & Substitute Parts

Part Overview

The P3206UATP is a 270V off-state, 150A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling in a compact 6-SMD, gull wing surface mount package. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3206UATP is determined by electrical and mechanical parameter equivalence. The critical parameters for substitution are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current handling (both 8/20µs and 10/1000µs waveforms)
• Hold current specification
• Element count and capacitance values
• Physical package configuration (6-SMD, gull wing)
• Mounting type (surface mount)

The P3206UALTP meets all these criteria as a direct substitute, with identical electrical specifications and package geometry. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The P3206UALTP is a direct electrical and mechanical equivalent to the P3206UATP. Selection between these parts is determined by regulatory and supply chain requirements:

• For applications requiring RoHS3 compliance, the P3206UALTP is the appropriate selection.
• For legacy system maintenance where RoHS compliance is not mandated, either part meets electrical specifications.
• The P3206UALTP is currently in active production with confirmed inventory availability, whereas the P3206UATP is obsolete.
• Both parts share identical electrical performance, package geometry, and handling requirements (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can P3206UALTP be used as a direct replacement for P3206UATP in existing designs?

A: Yes. The P3206UALTP is electrically and mechanically identical to the P3206UATP. All voltage ratings, current specifications, element count, and package dimensions are equivalent. PCB layout and circuit design require no modification.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The P3206UATP is obsolete and RoHS non-compliant. The P3206UALTP is active production and ROHS3 compliant. Electrical specifications and physical packaging are identical.

Q: Are there packaging differences between P3206UATP and P3206UALTP?

A: The P3206UATP is supplied in standard packaging. The P3206UALTP is supplied in tube packaging. Both use the same 6-SMD, gull wing component configuration and Modified MS-013 supplier device package. Tube packaging does not affect component performance or PCB assembly compatibility.

Q: Which part should be selected for new designs?

A: The P3206UALTP should be selected for new designs. It is in active production, offers RoHS3 compliance for regulatory alignment, and provides identical electrical and mechanical performance to the obsolete P3206UATP.

Q: Are the capacitance values interchangeable between these parts?

A: Yes. Both parts are available with 20pF or 30pF capacitance options. Selection is based on circuit requirements, not part number differences. Verify capacitance specification in your design documentation and order accordingly.
