PD55008L-E Equivalent & Substitute Parts

Part Overview

The PD55008L-E is an RF MOSFET LDMOS device manufactured by STMicroelectronics, designed for RF power amplification applications at 500 MHz. This component features a 12.5 V test voltage rating, 8 W output power capability, and 19 dB gain in a PowerFLAT™ (5x5) package configuration. The device is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across RF frequency response, power output, and package form factor while accommodating voltage and gain parameter variations inherent to the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PD55008L-E is determined by strict adherence to the following criteria:

Required Matching Parameters:

• Manufacturer: STMicroelectronics
• Technology: LDMOS
• Frequency: 500 MHz
• Package / Case: 8-PowerVDFN
• Supplier Device Package: PowerFLAT™ (5x5)
• Power - Output: 8 W
• Current Rating: 5 A
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Allowable Parameter Variations:

• Voltage - Test: May vary within product line specifications
• Voltage - Rated: May vary within product line specifications
• Gain: May vary within product line specifications
• Current - Test: May vary within product line specifications
• Product Status: Active status preferred for ongoing availability

The PD54008L-E qualifies as a substitute based on identical core RF performance parameters (500 MHz frequency, 8 W output power), matching package configuration, and active product status, despite variations in test voltage (7.5 V versus 12.5 V) and gain (15 dB versus 19 dB).

Parameter Comparison

Engineering Selection Recommendations

The PD54008L-E serves as the active equivalent for the obsolete PD55008L-E. Both devices share identical RF performance characteristics at 500 MHz with 8 W output power capability and matching PowerFLAT™ (5x5) package geometry. The substitute part maintains full ROHS3 compliance and equivalent moisture sensitivity specifications, ensuring compatibility with current manufacturing and environmental standards.

The primary distinction between these parts lies in voltage and gain parameters. The PD54008L-E operates at a lower test voltage (7.5 V versus 12.5 V) and reduced rated voltage (25 V versus 40 V), with correspondingly lower gain (15 dB versus 19 dB). These variations reflect design optimization within the LDMOS product family and do not compromise RF frequency response or power output specifications.

Selection of the PD54008L-E is appropriate for applications where the lower voltage and gain characteristics align with circuit design requirements. The active product status of the PD54008L-E ensures ongoing availability and supply chain continuity compared to the obsolete PD55008L-E.

Frequently Asked Questions (FAQ)

Q: Can the PD54008L-E directly replace the PD55008L-E in existing designs?

A: Direct replacement is possible when circuit design accommodates the lower test voltage (7.5 V) and reduced gain (15 dB) of the PD54008L-E. Both devices maintain identical RF frequency response (500 MHz), output power (8 W), and package configuration (PowerFLAT™ 5x5). Circuit validation is required to confirm compatibility with specific bias and impedance matching requirements.

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

A: The PD55008L-E and PD54008L-E differ in voltage specifications and gain. The PD55008L-E operates at 12.5 V test voltage with 40 V rated voltage and 19 dB gain. The PD54008L-E operates at 7.5 V test voltage with 25 V rated voltage and 15 dB gain. Both share identical frequency (500 MHz), output power (8 W), current rating (5 A), and package type (8-PowerVDFN PowerFLAT™ 5x5).

Q: Why is the PD55008L-E classified as obsolete?

A: The PD55008L-E is obsolete and no longer in active production. The PD54008L-E represents the current active product offering within the STMicroelectronics LDMOS RF MOSFET portfolio for this performance class.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the PD55008L-E and PD54008L-E use the 8-PowerVDFN package with PowerFLAT™ (5x5) form factor, ensuring identical PCB footprint and thermal characteristics.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both the PD55008L-E and PD54008L-E are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these devices?

A: Both parts carry Moisture Sensitivity Level 3 (168 Hours), requiring standard moisture control procedures during storage and handling.
