STMicroelectronics PD57006-E

Overview

PD57006-E from STMicroelectronics is a common-source, N-channel enhancement-mode lateral MOSFET RF power transistor in the PowerSO-10RF (formed lead) package. It delivers 6 W output power with 15 dB gain at 945 MHz under 28 V supply and 70 mA quiescent drain current, featuring 5 °C/W junction-to-case thermal resistance and 65 V drain-source breakdown voltage. It is engineered for high-linearity, broadband commercial and industrial RF amplification up to 1 GHz, notably in car mobile radio transmitters.

For engineers reviewing the PD57006-E datasheet, PD57006-E pinout, PD57006-E application, or PD57006-E equivalent, key selection criteria include its 945 MHz small-signal gain of 15 dB, 6 W saturated RF output capability, 45–50% drain efficiency, 10:1 load mismatch tolerance, and compatibility with surface-mount assembly in PowerSO-10RF.

Technical Context

This LDMOST device operates in common-source configuration with fixed 28 V DC bias and 70 mA IDQ, optimized for Class AB linear amplification across 925–960 MHz bands. Its gate-source threshold voltage ranges 2.0–5.0 V, and it exhibits low input capacitance (CISS = 27 pF) and moderate output capacitance (COSS = 14 pF) at 28 V, enabling stable impedance matching.

The transistor integrates ST's proprietary LDMOS process for enhanced thermal stability and reliability, supported by the JEDEC-approved PowerSO-10RF plastic SMD package. Its s-parameters confirm strong forward gain (|S21| > 10 dB up to 1 GHz) and acceptable input return loss (|S11| < −10 dB at 945 MHz), suitable for broadband driver and final-stage amplifier designs.

FAQ

What is the recommended gate bias voltage for PD57006-E in Class AB operation?

The datasheet specifies VGS(Q) = 2.0–5.0 V at IDQ = 70 mA and VDS = 28 V. For stable Class AB operation, a typical gate bias of 3.5 V is used with a 100 Ω series gate resistor and DC-blocking capacitor, as validated in the reference test circuit (Figure 23). This ensures repeatable quiescent current and minimizes thermal drift.

Can PD57006-E be used at frequencies outside the 925–960 MHz band?

Yes - s-parameter data confirms usable gain (>10 dB) up to 1.5 GHz, and impedance curves show stable ZIN/ZDL behavior from 50 MHz to 1.5 GHz. However, output power and efficiency degrade above 1 GHz; for 2.4 GHz applications, ST recommends the PD57018 family instead.

Is the PowerSO-10RF package RoHS-compliant and lead-free?

Yes - PD57006-E is supplied in an ECOPACK®-certified PowerSO-10RF package with lead-free second-level interconnect, compliant with JEDEC JESD97 and EU RoHS Directive 2011/65/EU. The inner box label indicates "Pb-free" and specifies maximum soldering profile limits.

How should the exposed drain pad be connected on the PCB?

The exposed drain pad must be soldered directly to a large, thermally optimized copper area on the PCB - minimum 200 mm² with ≥8 thermal vias (0.3 mm diameter, spaced ≤2 mm apart) connecting to internal or back-side ground planes. Per AN1294, this achieves the specified 5 °C/W RthJC and prevents thermal runaway at full 6 W output.
