PHDMI2FR4Z Equivalent & Substitute Parts

Part Overview

The PHDMI2FR4Z is an active Transient Voltage Suppressor (TVS) diode manufactured by Nexperia USA Inc., designed for general-purpose overvoltage protection applications. This steering-type TVS diode features a 3V typical clamping voltage with 7A peak pulse current capability in an ultra-compact 10-XFDFN surface mount package. The device is ROHS3 compliant and carries an unlimited moisture sensitivity level (MSL 1), making it suitable for high-reliability applications. Alternative equivalent parts may be required due to inventory constraints, specific packaging preferences, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PHDMI2FR4Z is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Package type: 10-XFDFN surface mount form factor
• Device architecture: Steering TVS diode with 4 unidirectional channels
• Voltage rating class: Devices with clamping voltage in the 3V to 9.2V range
• Peak pulse current capability: Minimum 2A at 8/20µs pulse width
• Low capacitance profile: Below 0.5pF at 1MHz for minimal signal distortion

Mechanical & Compliance Criteria:

• Surface mount compatibility with 10-pin DFN package footprint
• ROHS3 compliance certification
• Operating temperature range: Minimum -40°C to 85°C
• Moisture sensitivity level: MSL 1 (Unlimited)

The substitute part SP1004U-ULC-04UTG meets these criteria with compatible package geometry, compliance certifications, and electrical performance within acceptable operating parameters for general-purpose TVS applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PHDMI2FR4Z and SP1004U-ULC-04UTG are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, qualifying them for equivalent use in general-purpose TVS applications. Selection between these devices is based on application-specific voltage and current requirements:

The PHDMI2FR4Z is specified for applications requiring lower clamping voltage (3V typical) with higher peak pulse current handling (7A at 8/20µs). This device is optimal for protecting low-voltage signal lines and sensitive semiconductor inputs.

The SP1004U-ULC-04UTG provides higher clamping voltage (9.2V typical) with reduced peak pulse current capacity (2A at 8/20µs), suitable for applications requiring higher voltage threshold protection. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin in demanding environments.

Both devices maintain ROHS3 compliance and feature compatible 10-XFDFN package geometry for direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can SP1004U-ULC-04UTG directly replace PHDMI2FR4Z in all applications?

A: Direct replacement is limited to applications where the higher clamping voltage (9.2V vs. 3V) and lower peak pulse current (2A vs. 7A) are acceptable. Verify that the protected circuit can tolerate the increased clamping voltage threshold before substitution.

Q: Are the packages physically compatible?

A: Yes. Both devices use the 10-XFDFN surface mount package with identical footprint geometry, enabling direct PCB placement without layout modifications.

Q: What is the difference between Steering and Zener TVS diode types?

A: The PHDMI2FR4Z uses steering architecture optimized for rail-to-rail protection with bidirectional clamping capability. The SP1004U-ULC-04UTG uses Zener architecture. Both are suitable for general-purpose overvoltage suppression; device selection depends on specific circuit protection requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PHDMI2FR4Z and SP1004U-ULC-04UTG are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, meeting identical environmental and regulatory requirements.

Q: Which device should be selected for high-temperature applications?

A: The SP1004U-ULC-04UTG supports extended operating temperature range (-40°C to 125°C) compared to PHDMI2FR4Z (-40°C to 85°C), providing additional thermal margin for elevated ambient conditions.

Q: How do capacitance values affect circuit performance?

A: Both devices exhibit low capacitance (0.34pF and 0.2pF at 1MHz respectively), minimizing signal distortion in high-frequency applications. The SP1004U-ULC-04UTG offers slightly lower capacitance, beneficial for sensitive analog signal paths.
