Product details
Overview
CSD13385F5T from Texas Instruments is a 12-V, 15-mΩ N-Channel FemtoFET™ MOSFET in a 3-pin PICOSTAR (YJK) package measuring 1.53 mm × 0.77 mm × 0.36 mm max height, optimized for ultra-compact industrial load switching and mobile power management with 4.3-A continuous drain current at 25°C and integrated >4-kV HBM ESD protection.
For engineers reviewing the CSD13385F5T datasheet, CSD13385F5T pinout, CSD13385F5T application, or CSD13385F5T equivalent, this device delivers verified low RDS(on) (15 mΩ @ VGS = 4.5 V), ultra-low gate charge (Qg = 3.9 nC), and thermally robust operation from –55°C to 150°C - critical for space-constrained DC-DC converter enable paths and battery protection circuits.
Technical Context
This N-Channel enhancement-mode MOSFET uses TI's FemtoFET™ silicon process to achieve sub-1-mm width and 0.36-mm profile while maintaining stable threshold voltage (VGS(th) = 0.5–1.2 V) and low dynamic capacitance (Ciss = 519–674 pF, Coss = 305–396 pF).
Its gate drive compatibility with 1.8-V logic (RDS(on) = 26 mΩ @ VGS = 1.8 V), fast switching (td(on) = 7 ns, tf = 10 ns), and integrated body diode (VSD = 0.67–1.0 V @ ISD = 0.9 A) support high-frequency synchronous rectification and low-voltage rail switching in portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 12 V - Maximum drain-to-source blocking voltage; defines safe operating range in 3.3-V/5-V/12-V system rails. |
| RDS(on) | 15 mΩ @ VGS = 4.5 V - Enables <100-mW conduction loss at 0.9-A load; critical for thermal budget in sealed enclosures. |

FAQ
What is the maximum continuous drain current rating for CSD13385F5T at 25°C ambient?
The CSD13385F5T is rated for 4.3 A continuous drain current (ID) at TA = 25°C with minimum copper PCB layout, and 7.1 A with maximum copper. This rating assumes proper thermal management per TI's recommended PCB land pattern and is validated per JEDEC JESD51-2 standards. The CSD13385F5T datasheet specifies these values in its Absolute Maximum Ratings table.
Does CSD13385F5T include built-in ESD protection, and what are the certified ratings?
Yes, the CSD13385F5T integrates an ESD protection diode rated at >4-kV Human-Body Model (HBM) and >2-kV Charged-Device Model (CDM), as confirmed in the device's Features and Absolute Maximum Ratings sections. This eliminates the need for external ESD components in USB, I²C, and GPIO power-switching applications, and is verified per ANSI/ESDA/JEDEC JS-001 and JS-002 test standards.
What is the gate threshold voltage range for CSD13385F5T, and how does it support low-voltage logic drive?
The CSD13385F5T has a gate threshold voltage (VGS(th)) range of 0.5 V to 1.2 V, with a typical value of 0.8 V at IDS = 250 µA. This enables direct drive from 1.2-V, 1.8-V, and 2.5-V logic families without level shifters. The CSD13385F5T maintains 26-mΩ RDS(on) at VGS = 1.8 V, ensuring robust conduction even at lowest core voltages.
What package type and dimensions does CSD13385F5T use, and is it compatible with standard SMT processes?
The CSD13385F5T uses the PICOSTAR (YJK) package: a 3-pin, leadless, solder-land design measuring 1.53 mm × 0.77 mm × 0.36 mm max height. It is RoHS-compliant, moisture-sensitivity Level-1 (260°C peak reflow), and qualified for standard Type-3 solder paste and 0201-class pick-and-place equipment. The CSD13385F5T mechanical drawing and tape-and-reel specifications confirm full compatibility with IPC-7351B Class L footprints.
How does the low gate charge of CSD13385F5T improve switching efficiency in high-frequency applications?
The CSD13385F5T features a total gate charge (Qg) of 3.9 nC and gate-to-drain charge (Qgd) of 0.39 nC, resulting in a Qgd/Qg ratio of 0.1. This minimizes Miller plateau duration and reduces gate-drive power loss, enabling clean 1-MHz+ switching in DC-DC converters and motor drivers. The CSD13385F5T's low Qg directly lowers driver IC power consumption and improves overall system efficiency compared to alternatives with >6-nC Qg.
