Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD55008TR is determined by equivalence across the following critical parameters:

• Technology: LDMOS RF MOSFET architecture
• Frequency Response: 500 MHz operational specification
• Electrical Performance: 17 dB gain, 8W output power, 12.5V test voltage, 4A current rating, 40V rated voltage
• Package Compatibility: PowerSO-10 with exposed bottom pad mechanical and thermal interface
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status
• Moisture Sensitivity: MSL 3 (168 Hours) handling requirements

Substitute parts must maintain identical electrical characteristics, package footprint, and compliance certifications to ensure direct replacement capability without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

The PD55008-E is a direct electrical and mechanical equivalent to the PD55008TR. Both devices share identical electrical specifications, package geometry, and regulatory compliance certifications. The primary distinction is product status and packaging format.

PD55008-E Selection Basis:

The PD55008-E maintains active product status with STMicroelectronics, ensuring continued availability and technical support. All electrical parameters, including frequency response, gain, voltage ratings, current ratings, and output power, are identical to the PD55008TR. The PowerSO-10 package with exposed bottom pad provides equivalent thermal and electrical performance. Both devices comply with ROHS3 requirements and carry identical moisture sensitivity specifications.

The PD55008-E is supplied in tube packaging rather than tape and reel format. This packaging difference does not affect electrical performance or mechanical compatibility but may require adjustment to assembly line handling procedures if automated tape-fed equipment is currently in use.

Frequently Asked Questions (FAQ)

Q: Can the PD55008-E directly replace the PD55008TR in existing designs?

A: Yes. The PD55008-E provides direct electrical and mechanical substitution. All RF performance parameters, voltage ratings, current ratings, and package dimensions are identical. The device operates at 500 MHz with 17 dB gain and 8W output power under identical test conditions.

Q: What is the difference between the PD55008TR and PD55008-E?

A: The primary differences are product status and packaging format. The PD55008TR is obsolete and supplied in tape and reel format. The PD55008-E is an active product supplied in tube packaging. Electrical specifications and package geometry are identical.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the PD55008TR and PD55008-E carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level 3 (168 Hours) specifications. No additional compliance considerations apply to substitution.

Q: Does the packaging format change affect circuit performance?

A: No. Packaging format (tape and reel versus tube) affects only material handling and assembly logistics. Electrical performance, thermal characteristics, and mechanical fit are unaffected by packaging format.

Q: What is the PowerSO-10 package with exposed bottom pad?

A: PowerSO-10 is a surface-mount package with 10 leads and an exposed thermal pad on the bottom surface. The exposed pad provides direct thermal contact to the PCB, improving heat dissipation for RF power applications. Both the PD55008TR and PD55008-E use this identical package configuration.

Q: Are there any moisture handling differences between these parts?

A: No. Both devices carry identical moisture sensitivity level 3 (168 Hours) specifications. Standard MSL 3 handling procedures apply to both the PD55008TR and PD55008-E.

Q: Can I use the PD55008-E in high-frequency RF applications?

A: Yes. The PD55008-E is specified for 500 MHz operation with 17 dB gain and 8W output power. It is designed for RF power amplification applications within this frequency range.
