Product details
Overview
PD54008TR-E from STMicroelectronics is an N-channel enhancement-mode lateral MOSFET RF power transistor in common-source configuration, rated for 8 W output power at 500 MHz with 11.5 dB gain and 50% drain efficiency under 7.5 V/150 mA bias. It features 25 V drain-source breakdown voltage, 1.2 °C/W junction-to-case thermal resistance, and operates up to 1 GHz in commercial and industrial broadband amplifiers.
For engineers reviewing the PD54008TR-E datasheet, PD54008TR-E pinout, PD54008TR-E application, or PD54008TR-E equivalent, key selection criteria include its PowerSO-10RF (formed lead) SMD package, RF linearity performance at 470–520 MHz, thermal stability under pulsed and CW operation, and compatibility with portable radio and UHF transmitter front-end designs.
Technical Context
This device implements ST's LDMOS technology optimized for high-gain, broadband RF power amplification in common-source topology. Its gate-source threshold voltage (2.0–5.0 V) and transconductance (2.0–2.5 mho) support stable Class AB biasing, while low input/output capacitances (CISS = 91 pF, COSS = 68 pF) enable wideband impedance matching from 175 MHz to 1 GHz.
The PowerSO-10RF package integrates a thermally enhanced leadframe with optimized RF grounding and controlled parasitic inductance. Its formed-lead gull-wing geometry ensures reliable reflow soldering while maintaining low RthJC (1.2 °C/W), critical for sustaining 73 W power dissipation at TCASE = 70°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MRF300AN | Higher POUT (30 W), TO-247 package, 28 V operation - requires larger heatsink and different bias network | Suitable for fixed infrastructure with higher power budget; not drop-in for space-constrained portable designs | Select when >10 W output or 28 V system architecture is required; verify thermal interface compatibility |
| PD57003-E | Same PowerSO-10RF package, 3 W POUT, lower gain (10 dB), improved efficiency at 150 MHz - optimized for HF/VHF | Better suited for 30–175 MHz amateur radio and marine VHF; insufficient gain/power for UHF portable radio | Choose for cost-sensitive, lower-frequency applications where 8 W is unnecessary and board space is constrained |
Compared with MRF300AN and PD57003-E, PD54008TR-E uniquely balances 8 W output, 11.5 dB gain, and PowerSO-10RF SMD compatibility - making it optimal for UHF portable radios where size, efficiency, and thermal management are co-constrained.

FAQ
What is the recommended gate bias voltage for linear operation?
The datasheet specifies VGS(Q) = 2.0–5.0 V at ID = 150 mA and VDS = 10 V. For optimal linearity at 500 MHz, a gate bias of 3.2 V is recommended to set IDQ at 150 mA under 7.5 V drain supply, balancing gain, efficiency, and IMD3 performance.
Can PD54008TR-E be used in Class C amplifier configurations?
No - the device is characterized and qualified for Class AB operation only. Its transconductance profile and thermal design assume continuous conduction angle; Class C use risks thermal runaway and violates absolute maximum ratings for junction temperature and power dissipation.
Is the PowerSO-10RF package RoHS-compliant and halogen-free?
Yes - PD54008TR-E carries ECOPACK®2 certification, meeting RoHS Directive 2011/65/EU and IEC 61249-2-21:2011 for halogen-free materials. The package uses lead-free matte tin plating and green molding compound compliant with ST's environmental policy.
What is the maximum allowable drain voltage for safe operation?
V(BR)DSS is rated at 25 V minimum. For reliable long-term operation, the maximum continuous drain voltage must not exceed 7.5 V under RF drive conditions, as specified in all dynamic test conditions. Transient spikes above 9.5 V require external clamping per Figure 10 and Table 5.
