STMicroelectronics PD20015C

Overview

PD20015C from STMicroelectronics is a common-source N-channel enhancement-mode lateral DMOS RF power transistor designed for broadband 2 GHz mobile infrastructure amplifiers. It delivers 15 W output power with 11 dB gain at 13.6 V supply, features BeO-free M243 hermetic package, ESD protection (HBM Class 2), and 200 °C max junction temperature.

For engineers reviewing the PD20015C datasheet, PD20015C pinout, PD20015C application, or PD20015C equivalent, key selection criteria include its 2 GHz P3dB performance (23 W), drain-source breakdown voltage (40 V), thermal resistance (1.4 °C/W), linearity under load mismatch (20:1 VSWR tolerance), and gate threshold voltage (4.2 V typ).

Technical Context

The PD20015C operates in common-source configuration with fixed 350 mA quiescent drain current, optimized for Class AB linear amplification up to 2 GHz. Its LDMOS structure provides high transconductance and low output capacitance (C_OSS = 35 pF, C_RSS = 1.0 pF) to support broadband matching.

Thermal design is enabled by direct die-to-case conduction via the M243 metal-ceramic package (R_thJC = 1.4 °C/W), supporting continuous 93 W dissipation at T_C = 70 °C. ESD robustness meets HBM Class 2 (≥2 kV) without external protection circuitry.

FAQ

What is the recommended gate bias voltage for linear operation?

The datasheet specifies V_GS(Q) = 4.2 V typical at I_DQ = 350 mA and V_DS = 10 V. For stable Class AB operation at 13.6 V, a precision 4.2 V gate bias with <±50 mV tolerance is required to maintain optimal linearity and efficiency across temperature.

Can PD20015C operate at 2.4 GHz?

No - the device is characterized and guaranteed only up to 2 GHz. At 2.4 GHz, gain drops below 8 dB and P3dB falls to ~12 W per typical curves; harmonic content and thermal instability increase significantly beyond specification limits.

Is external ESD protection required on the gate?

No - the integrated ESD protection meets HBM Class 2 (≥2 kV), sufficient for standard PCB handling and assembly. However, gate traces must avoid long stubs or unshielded routing near noisy digital lines to prevent coupling-induced failure.

What is the maximum safe DC drain voltage during startup?

The absolute maximum V_(BR)DSS is 40 V, but safe DC application requires limiting V_DS to ≤25 V during bias sequencing to avoid avalanche stress before gate control is established. Use soft-start circuits or sequenced supplies to enforce this limit.
