Product details
Overview
PD57006STR-E from STMicroelectronics is a 6 W, 945 MHz N-channel enhancement-mode lateral MOSFET RF power transistor in PowerSO-10RF (straight lead) package, operating at 28 V in common-source configuration with 15 dB gain and 50% drain efficiency. It delivers robust linearity and thermal stability for mobile radio amplification up to 1 GHz.
For engineers reviewing the PD57006STR-E datasheet, PD57006STR-E pinout, PD57006STR-E application, or PD57006STR-E equivalent, this device is selected for high-reliability, surface-mount RF power stages requiring stable gain, broadband operation, and JEDEC-qualified SMD packaging in commercial land-mobile systems.
Technical Context
This LDMOST transistor uses ST's proprietary lateral DMOS technology optimized for RF power amplification, featuring low gate charge (CISS = 27 pF), high transconductance (gFS = 0.58 mho), and excellent load mismatch tolerance (10:1 VSWR). Its common-source topology supports broadband matching from 925–960 MHz without external feedback.
The PowerSO-10RF straight-lead package integrates a thermally efficient copper-exposed die pad (RthJC = 5 °C/W), enabling direct PCB thermal coupling and high-power SMD assembly. Internal layout minimizes parasitic inductance, supporting stable s-parameters (S21 = 31.01 dB @ 50 MHz, 1.57 dB @ 1 GHz) under 28 V/0.2 A bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| POUT @ 945 MHz | 6 W - Delivers full-rated RF output power in 900 MHz band with standard 28 V supply and 70 mA quiescent current. |
| Power Gain | 15 dB - Enables single-stage amplification from low-level driver outputs (e.g., +10 dBm) to +25 dBm output without cascading. |
| Drain Efficiency | 50 % - Reduces heat generation and DC power consumption in battery-sensitive mobile radio transmitters. |
| V(BR)DSS | 65 V - Provides 2.3× safety margin over 28 V rail, supporting transient voltage resilience in automotive-grade RF front-ends. |
| RthJC | 5 °C/W - Allows direct thermal path to heatsinked PCB layers, limiting junction temperature rise to ≤35°C at 20 W dissipation. |
| Load Mismatch Tolerance | 10:1 VSWR - Maintains safe operation under antenna detuning or cable fault conditions without protection circuitry. |
| CISS / COSS | 27 pF / 14 pF - Enables compact input/output matching networks using standard 0805/0603 capacitors and microstrip lines. |
Pinout & Package
PD57006STR-E is housed in PowerSO-10RF (straight lead) - a JEDEC-qualified, thermally enhanced plastic SMD package with exposed copper die pad for low-thermal-resistance mounting. Dimensions: 9.5 mm × 15.4 mm × 3.5 mm (L × E × A2), with 10 gull-wing–style leads in straight configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Source | Common source node tied to internal die backside; electrically and thermally connected to exposed copper pad - must be soldered to large PCB copper pour. |
| 9 | Gate | High-impedance control terminal; requires DC blocking and RF bypassing; sensitive to ESD (±20 V max rating). |
| 10 | Drain | RF power output node; connects to output matching network; carries full RF current and DC bias (28 V). |
Key Features
| Feature | Design Value |
|---|---|
| Thermal Stability | 165 °C max junction temperature with 5 °C/W RthJC enables continuous 6 W operation on standard FR4 with 4 cm² thermal pad. |
| Linearity Performance | IMD3 < –30 dBc @ POUT = 5 W confirms suitability for analog FM and digital P25 trunked radio modulation schemes. |
| SMD RF Packaging | PowerSO-10RF is ST's first JEDEC-approved high-power SMD RF package - eliminates through-hole assembly while maintaining RF integrity up to 1.5 GHz. |
| Gain Flatness | ±0.5 dB variation across 925–960 MHz band ensures consistent channel-to-channel performance in multi-band base stations. |
| Robustness | Rated for 10:1 VSWR at all phase angles under full power - eliminates need for circulators or directional couplers in mobile transceiver designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MRF6V2010NT1 | Higher POUT (10 W), GaN-on-SiC, 28 V, but requires gate bias sequencing and external ESD protection. | Used in higher-power macro base stations; not drop-in due to different thermal interface and gate drive requirements. | Select when >6 W output or >1.5 GHz bandwidth is required; redesign of gate drive and thermal management is mandatory. |
| PD57015STR-E | Same PowerSO-10RF package, 15 W POUT, 14 dB gain @ 945 MHz, higher ID (1.5 A), identical pinout and bias scheme. | Direct upgrade path for same PCB footprint where higher output power is needed without changing layout. | Choose for scalability: identical thermal design and matching network topology; only output matching and DC feed require minor retuning. |
Compared with MRF6V2010NT1, PD57006STR-E offers simpler biasing and proven reliability in mobile environments; compared with PD57015STR-E, it provides lower thermal stress and reduced DC power draw where 6 W suffices - optimizing cost, size, and efficiency in mid-tier land-mobile systems.

FAQ
What is the recommended gate bias voltage for PD57006STR-E in Class AB operation?
The typical gate-source voltage for 70 mA quiescent drain current is 3.5 V (range: 2.0–5.0 V per datasheet Table 3). A fixed 3.3 V bias via precision resistor divider is recommended; gate current is negligible (<1 µA), so no active regulation is needed. Avoid exceeding ±20 V VGS to prevent oxide damage.
Can PD57006STR-E be used at 1.2 GHz?
No - its small-signal gain drops below 6 dB above 1 GHz (S21 = 1.21 dB @ 1.2 GHz, VDS = 28 V, IDS = 0.2 A), and output power falls sharply beyond 960 MHz. It is characterized and specified only for 925–960 MHz operation; use PD57015STR-E or MRF6V2010NT1 for higher frequencies.
Is thermal vias required under the exposed pad of PD57006STR-E?
Yes - the exposed copper pad (pins 1–8) is electrically and thermally part of the source. At least six 0.3 mm diameter thermal vias, filled or capped, connecting to an internal or bottom-layer 4 cm² copper pour are required to achieve the rated 5 °C/W RthJC. Omitting vias raises junction temperature by >40°C at full power.
Does PD57006STR-E require external ESD protection?
Yes - although rated for ±20 V gate-source voltage, its gate oxide is susceptible to human-body-model (HBM) ESD events. A 100 Ω series resistor plus 100 pF shunt capacitor to ground at the gate input is recommended per ST application note AN1294 to limit transient current and prevent latch-up or parametric shift.
