Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PESD36VS2UT are identified based on electrical and mechanical compatibility within the following criteria:

Electrical Compatibility Parameters:

• Voltage - Reverse Standoff (Typ): 36V (Max) — substitute must match or exceed this specification
• Voltage - Breakdown (Min): 40V — substitute must match or exceed this specification
• Mounting Type: Surface Mount — substitute must be surface mount
• Package / Case: TO-236-3, SC-59, SOT-23-3 — substitute must use compatible package footprint
• Type: Zener — substitute must be Zener-type TVS diode
• Unidirectional Channels: 2 — substitute must provide 2 unidirectional channels
• Operating Temperature Range: -55°C to 150°C — substitute must support this range
• RoHS3 Compliance: Required — substitute must maintain RoHS3 compliance status

Mechanical Compatibility Parameters:

• Supplier Device Package: SOT-23-3 (TO-236) — substitute must use SOT-23 or equivalent footprint

The PE4136C2A-AU_R1_000A1 meets all electrical and mechanical compatibility criteria for substitution. This part maintains identical reverse standoff voltage, breakdown voltage, package type, channel configuration, and temperature range specifications while providing enhanced peak pulse current capability and clamping voltage performance.

Parameter Comparison

Engineering Selection Recommendations

Both the PESD36VS2UT and PE4136C2A-AU_R1_000A1 are active products with RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for current applications.

PESD36VS2UT Selection Criteria:

• Applications requiring low capacitance (17pF @ 1MHz) for high-speed signal integrity
• Systems with strict peak pulse current limitations (2.5A maximum)
• Nexperia supply chain preference or existing qualification documentation

PE4136C2A-AU_R1_000A1 Selection Criteria:

• Applications requiring higher peak pulse current handling (9A @ 8/20µs)
• Systems tolerating higher clamping voltage (75V vs. 60V)
• Automotive-grade applications with AEC-Q101 qualification
• Higher capacitance tolerance acceptable (100pF @ 1MHz maximum)
• Tape & Reel packaging for automated assembly processes

Both devices maintain identical reverse standoff voltage (36V), breakdown voltage (40V), operating temperature range (-55°C to 150°C), and package footprint compatibility (SOT-23-3). Selection between these parts depends on application-specific requirements for current handling, clamping voltage, and capacitance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the PE4136C2A-AU_R1_000A1 directly replace the PESD36VS2UT in existing designs?

A: Direct replacement is possible from a package and voltage standpoint. Both devices use SOT-23-3 footprint and share identical reverse standoff (36V) and breakdown (40V) voltages. However, the PE4136C2A-AU_R1_000A1 exhibits higher peak pulse current (9A vs. 2.5A) and higher clamping voltage (75V vs. 60V). Circuit validation is required to confirm these parameter differences do not affect system performance.

Q: What is the primary difference in capacitance between these two parts?

A: The PESD36VS2UT has 17pF capacitance at 1MHz, while the PE4136C2A-AU_R1_000A1 has a maximum of 100pF at 1MHz.
