Product details
Overview
PD57006S from STMicroelectronics is a common-source N-channel enhancement-mode lateral LDMOS RF power transistor in PowerSO-10RF straight-lead plastic package, delivering 6 W output power with 15 dB gain at 945 MHz and 28 V supply, optimized for car mobile radio amplifiers requiring high linearity and thermal stability up to 1 GHz.
For engineers reviewing the PD57006S datasheet, PD57006S pinout, PD57006S application, or PD57006S equivalent, this device serves as a high-efficiency, SMD-compatible RF power stage for 900 MHz band base stations, mobile two-way radios, and industrial broadband amplifiers where drain efficiency ≥45%, VSWR tolerance up to 10:1, and junction temperature resilience to 165°C are critical.
Technical Context
This device operates in common-source configuration with gate-controlled lateral conduction, leveraging ST's LDMOS process for high transconductance (0.58 mho) and low input/output capacitances (Ciss = 27 pF, Crss = 0.9 pF). Its 5 °C/W junction-to-case thermal resistance enables stable 6 W operation at Tc = 70°C without forced cooling.
The PowerSO-10RF straight-lead package integrates optimized microstrip matching networks-Zin ≈ 4.04 – j2.30 Ω and ZDL ≈ 3.86 + j10.58 Ω at 945 MHz-enabling direct integration into 50 Ω systems with minimal external tuning. Bias stability is maintained across –25°C to +100°C case temperature via predictable VGS(Q) shift (2.0–5.0 V at ID = 70 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| POUT @ 945 MHz | 6 W - delivers full rated RF output into matched 50 Ω load at 28 V, enabling Class AB amplifier stages for mobile radio front-ends |
| Power Gain | 15 dB typ. - provides sufficient small-signal gain to drive final stage without intermediate amplification in compact transceivers |
| Drain Efficiency | 50% max @ POUT = 6 W - minimizes heat generation and DC power draw in battery-sensitive or thermally constrained enclosures |
| V(BR)DSS | 65 V - supports safe operation with 28 V rail plus transient margin, eliminating need for external overvoltage clamping |
| Rth(j-c) | 5 °C/W - allows 20 W dissipation at Tc = 70°C, enabling reliable continuous-wave operation without heatsink derating |
| Load Mismatch Tolerance | 10:1 VSWR at all phase angles - sustains full 6 W output under severe antenna mismatch, critical for vehicular mobile installations |
| Ciss / Crss | 27 pF / 0.9 pF - low feedback capacitance ensures unconditional stability and simplifies input/output matching network design |
Pinout & Package
PD57006S uses the PowerSO-10RF straight-lead plastic package (JEDEC-compliant), featuring gull-wing–free lead geometry optimized for RF thermal and electrical performance. The package includes integrated source grounding tabs and controlled lead inductance for stable high-frequency operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GATE | Control electrode | Accepts DC bias (VGS(Q) = 2.0–5.0 V) and RF input signal; requires series gate resistor for stability per AN1294 |
| SOURCE | Common reference node | Internally bonded to exposed metal pad; must be soldered to large copper pour for thermal and RF grounding |
| DRAIN | RF power output terminal | Connects to output matching network; carries full RF current and DC supply (28 V); requires low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| Common-source LDMOS architecture | Enables single-ended RF power amplification with inherent high gain and wideband linearity up to 1 GHz |
| PowerSO-10RF straight-lead package | JEDEC-qualified SMD format with 0.23–0.32 mm lead thickness, enabling automated assembly and repeatable thermal interface |
| 10:1 VSWR ruggedness | Guarantees no latch-up or parametric shift during antenna detuning events-essential for mobile radio field reliability |
| 65 V drain-source breakdown | Permits 28 V operation with >100% transient headroom, reducing need for external TVS protection in 24 V vehicle systems |
| 165°C max junction temperature | Supports extended lifetime in sealed enclosures or high-ambient environments (e.g., under-hood automotive) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MRF6P27050HR5 | Higher POUT (50 W), GaN-on-SiC, 28 V, but requires complex gate bias sequencing and external thermal interface | Targeted at macro-cell base stations-not cost-optimized for mobile radio or ISM transmitters | Select only when >10 W output and >3.5 GHz bandwidth are required; not drop-in compatible |
| PD57003S | Same PowerSO-10RF package, lower POUT (3 W), identical pinout and bias scheme, 50% lower gain (12 dB) | Used in lower-power handheld radios and battery-operated modules where thermal budget is tighter | Drop-in replacement for reduced-power variants; shares layout, BOM, and thermal design |
Compared with PD57006S, MRF6P27050HR5 offers higher power and frequency range but demands rigorous thermal management and gate protection, whereas PD57003S provides identical footprint and bias simplicity at half the output-making it ideal for scalable product families.

FAQ
What is the recommended gate bias voltage for PD57006S in Class AB operation?
The datasheet specifies VGS(Q) = 2.0–5.0 V at IDQ = 70 mA and VDS = 28 V. For optimal linearity and efficiency at 6 W output, ST recommends setting VGS to 3.5 V using a precision bias network, verified by measuring quiescent drain current on the evaluation board per AN1294.
Can PD57006S operate safely at 32 V DC supply?
No-absolute maximum V(BR)DSS is 65 V, but the device is characterized and qualified only up to 28 V. Operating above 28 V risks exceeding safe SOA limits, especially under RF load mismatch, and voids ST's reliability warranty. Use only 28 V ±10% per specification.
Is thermal pad soldering required for PD57006S in PowerSO-10RF straight-lead package?
Yes-the exposed source pad beneath the package must be fully soldered to a minimum 200 mm² copper area with ≥4 thermal vias (0.3 mm diameter) to achieve the rated 5 °C/W Rth(j-c). Omitting this compromises thermal performance and risks junction overheating beyond 165°C.
Does PD57006S require external input/output matching components?
Yes-while ZIN and ZDL impedances are provided (e.g., 4.04 – j2.30 Ω at 945 MHz), the device requires discrete LC matching networks to transform to 50 Ω. ST's reference design (SC15200 schematic) uses 47 pF capacitors, 15 nH inductor, and microstrip sections-no internal matching is integrated.
