STMicroelectronics SD57060-01

Overview

SD57060-01 from STMicroelectronics is a common-source N-channel enhancement-mode lateral RF power MOSFET designed for broadband base station amplifiers up to 1.0 GHz. It delivers 60 W output power with 13 dB gain at 945 MHz under 28 V drain supply and 100 mA quiescent drain current, features BeO-free M250 ceramic package, and supports high linearity in commercial cellular infrastructure.

For engineers reviewing the SD57060-01 datasheet, SD57060-01 pinout, SD57060-01 application, or SD57060-01 equivalent, this page provides verified thermal resistance (1.1 °C/W), junction temperature rating (200 °C), drain-source breakdown voltage (65 V), gate-source voltage range (±20 V), and dynamic efficiency data at 945 MHz - all critical for RF PA stage design and thermal management validation.

Technical Context

The SD57060-01 operates in common-source configuration with lateral DMOS architecture optimized for high-gain, broadband RF amplification. Its static characteristics include V_GS(th) of 2.0–5.0 V and low R_DS(on) (0.7–0.8 V at V_GS = 10 V, I_D = 3 A), enabling efficient Class AB operation.

Dynamic performance is characterized at 945 MHz with 28 V V_DD, delivering 60 W P_OUT, 13–15 dB power gain, and 53–60% drain efficiency. S-parameter data confirms stable input/output matching across 50–1500 MHz, with s21 magnitude >22 dB at 50 MHz and >0.5 dB gain margin up to 1.5 GHz.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous drain current rating for SD57060-01?

The absolute maximum continuous drain current is 7 A at T_CASE = 25 °C, as specified in Table 1 of the datasheet. However, practical operation is limited by thermal constraints: at T_CASE = 70 °C, the device supports up to 108 W power dissipation, corresponding to ~3.8 A average drain current under typical 28 V Class AB conditions with 60 W RF output.

Does SD57060-01 require external gate protection diodes?

Yes - the gate-source voltage rating is ±20 V, and the device lacks integrated ESD protection. ST's recommended test circuit (Figure 12) includes a 1 kΩ surface-mount resistor (R1) and a shield bead (FB1) to limit transient gate current. External Zener clamps (e.g., 15 V bidirectional TVS) are advised for production designs exposed to handling or system-level ESD events.

Can SD57060-01 operate reliably at 32 V drain supply?

Yes - the datasheet includes performance curves at V_DD = 32 V (Figure 4, Figure 5), showing 60 W P_OUT and 12–13 dB gain at 945 MHz. However, V_(BR)DSS is 65 V, so 32 V operation maintains 2× voltage margin. Thermal design must account for increased power dissipation: R_thJC remains 1.1 °C/W, but junction temperature rises proportionally with V_DD × I_D.

Is the M250 package lead-free and RoHS-compliant?

Yes - revision 6 of the datasheet (July 2007) explicitly added "lead free info", and ST's product change notifications confirm SD57060-01 as RoHS-compliant with lead-free terminations and BeO-free ceramic construction. The M250 package uses matte tin plating on copper flange and lead-free epoxy encapsulation per JEDEC J-STD-020 moisture sensitivity level 3.
