Product details
Overview
PD55015TR-E from STMicroelectronics is a common-source, N-channel enhancement-mode lateral MOSFET RF power transistor in the LdmoST plastic family. It delivers 15 W output power with 14 dB gain at 500 MHz and 12.5 V supply, operates up to 1 GHz, and features excellent thermal stability and linearity for broadband commercial/industrial RF amplification.
For engineers reviewing the PD55015TR-E datasheet, PD55015TR-E pinout, PD55015TR-E application, or PD55015TR-E equivalent, key selection criteria include its PowerSO-10RF SMD package, 1.2 °C/W junction-to-case thermal resistance, 40 V drain-source breakdown voltage, 50–55% drain efficiency at 15 W, and load mismatch tolerance up to 20:1 VSWR.
Technical Context
This device uses ST's LDMOS technology optimized for high-gain, broadband RF power amplification in common-source configuration. Its design targets stable operation under wide temperature variation (−65°C to +150°C storage) and high-reliability SMD assembly via JEDEC-approved PowerSO-10RF packaging.
The transistor supports dynamic biasing across 150 mA to 2.25 A quiescent drain current, with verified s-parameter performance up to 1.5 GHz at multiple bias points (225 mA, 1.2 A, 2.25 A), enabling flexible PA stage design for mobile radio and industrial transmitters.

FAQ
What is the recommended gate bias voltage for linear operation at 15 W output?
The datasheet specifies VGS(Q) = 2.0–5.0 V at ID = 150 mA for quiescent bias. For linear 15 W operation at 500 MHz, typical gate bias is 3.2–3.8 V with 12.5 V drain supply, verified by Figures 15 and 24 showing peak POUT near VGS = 3.0 V. External gate resistor network per AN1294 ensures stability.
Can PD55015TR-E be used in Class C or Doherty configurations?
No - the device is characterized and qualified only for Class AB operation. Its static and dynamic parameters (e.g., gFS = 2.0–2.5 mho, VDS(ON) = 0.8 V) and thermal design are optimized for linear AB biasing. Class C or Doherty use would exceed safe operating area limits and invalidate reliability data.
Is the PowerSO-10RF package RoHS and REACH compliant?
Yes - PD55015TR-E carries ECOPACK®2 compliance, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and compliance documentation are available on www.st.com under ECOPACK® specifications for PowerSO-10RF.
What is the maximum continuous drain current rating?
ID = 5 A is the absolute maximum rating at TCASE = 25°C (Table 2). In practical operation at 12.5 V and 15 W output, typical ID peaks near 2.25 A (per Table 11), well within safe SOA limits defined in Figure 6. Derating is required above 70°C case temperature per RthJC = 1.2 °C/W.
