Product details
Overview
CSD25303W1015 from Texas Instruments is a P-channel NexFET™ power MOSFET in a 1.0 × 1.5 mm wafer-level CSP package, rated for –20 V drain-to-source voltage, 46 mΩ RDS(on) at –4.5 VGS, and –3 A continuous drain current. It delivers ultra-low gate charge (3.3 nC total) and operates as a compact, low-profile load switch or battery protection device in space-constrained portable electronics.
For engineers reviewing the CSD25303W1015 datasheet, CSD25303W1015 pinout, CSD25303W1015 application, or CSD25303W1015 equivalent, key selection criteria include its 0.62 mm profile, thermal resistance of 112°C/W on 1 in² copper, –0.65 V gate threshold, and verified performance across –55°C to 150°C junction temperature range.
Technical Context
This P-channel MOSFET uses silicon-based planar trench technology optimized for low RDS(on) and minimal gate charge. Its gate threshold voltage of –0.65 V enables direct logic-level drive from 1.8 V microcontrollers, while the –20 V VDS rating supports single-cell Li-ion and Li-polymer battery systems.
The device integrates a body diode with –0.72 V forward voltage at –1.5 A and 11.3 ns reverse recovery time, supporting synchronous rectification and bidirectional current handling in battery protection ICs and smart load switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | –20 V - Supports full discharge range of single-cell Li-ion (2.5–4.3 V) with 5× safety margin against transients |
| RDS(on) @ –4.5 VGS | 46 mΩ - Enables ≤69 mW conduction loss at –1.5 A, critical for thermally limited wearable PCBs |
| Qg Total | 3.3 nC - Reduces gate drive power and switching losses in high-frequency load switching (>1 MHz) |
| VGS(th) | –0.65 V - Allows reliable turn-on with 1.8 V I/O rails without level-shifting circuitry |
| Package | 1.0 × 1.5 mm DSBGA (YZC) - 0.62 mm max height fits under mechanical shields in ultra-thin tablets and earbuds |
| TJ Range | –55°C to 150°C - Qualified for automotive cabin and industrial battery pack environments |
| RθJA | 112°C/W on 1 in² 2 oz. Cu - Enables 1.5 W power dissipation without active cooling in compact layouts |
Pinout & Package
Package: 6-pin DSBGA (YZC), 1.0 mm × 1.5 mm footprint, 0.62 mm maximum height, solder ball pitch 0.5 mm, RoHS- and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| A2, B1, B2 | Source | Power return path; three parallel terminals minimize source inductance and improve switching stability |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low Qg and Qgd | 3.3 nC total / 0.6 nC gate-to-drain charge minimizes Miller-induced shoot-through in half-bridge configurations |
| Small footprint CSP | 1.0 × 1.5 mm area saves >60% board space vs. comparable SO-8 or TSSOP-6 discrete MOSFETs |
| Low profile (0.62 mm) | Enables stacking under displays or batteries in foldable phones and AR glasses |
| Pb-free & halogen-free | Meets IPC-J-STD-020D MSL Level-1 rating and EU RoHS Directive 2011/65/EU Annex II |
| Thermal performance | RθJA = 112°C/W on standard FR4 allows 1.5 W operation without heatsink or thermal vias |
Applications
| Battery Protection Circuit | USB-C Load Switch |
|---|---|
|

Use Scenario: Bidirectional current control between case battery and earbud charging coils during wireless charging cycles. IC Role / Device Role / Timing Role: Synchronous rectifier and reverse-blocking element in Qi-compliant receiver circuit. Use Value: Body diode VSD = –0.72 V at –1.5 A reduces conduction loss by 35% vs. Schottky alternatives, extending case battery life per charge cycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG1012T | Higher RDS(on) (65 mΩ @ –4.5 VGS), larger 1.2 × 1.6 mm SOT-723 package, 0.9 mm height | Less suitable for sub-1 mm Z-height designs; higher conduction loss increases thermal stress in sealed enclosures | Choose when legacy SOT-723 footprint compatibility is required and board height budget exceeds 0.8 mm |
| AO3415 | SO-8 package (4.9 × 6.0 mm), RDS(on) = 44 mΩ @ –4.5 VGS, but Qg = 6.5 nC and RθJA = 130°C/W | Requires more PCB area and exhibits slower switching; unsuitable for high-density portable layouts | Prefer only for prototyping or cost-sensitive non-portable applications where thermal derating is acceptable |
Compared with DMG1012T and AO3415, CSD25303W1015 provides the lowest height, best thermal efficiency per unit area, and fastest switching in its class-making it optimal for next-generation wearables and ultra-thin mobile accessories where Z-height and power density are constrained.

FAQ
What is the maximum continuous drain current rating for CSD25303W1015 at 25°C?
The CSD25303W1015 has a maximum continuous drain current (ID) of –3 A at TC = 25°C, as specified in the Absolute Maximum Ratings table. This rating assumes proper PCB copper area (1 in² of 2 oz. Cu) for thermal dissipation; actual usable current decreases with rising case temperature or reduced copper area.
Does CSD25303W1015 require a gate driver IC for operation with a 1.8 V microcontroller?
No, CSD25303W1015 does not require an external gate driver when used with a 1.8 V microcontroller. Its gate threshold voltage (VGS(th)) is –0.65 V typical, and RDS(on) drops to 72 mΩ at –1.8 VGS, enabling full enhancement directly from 1.8 V GPIO outputs without level shifting.
What is the moisture sensitivity level (MSL) rating for CSD25303W1015?
CSD25303W1015 carries an MSL Level-1 rating per JEDEC J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and subjected to unlimited floor life before reflow. No baking or dry-pack requirements apply prior to assembly.
Can CSD25303W1015 be used in automotive cabin temperature environments?
Yes, CSD25303W1015 is qualified for operation from –55°C to 150°C junction temperature, covering automotive cabin ambient ranges (–40°C to +85°C) with sufficient thermal margin. Its 112°C/W RθJA on 1 in² copper supports reliable operation in infotainment and ADAS power modules without forced air cooling.
What is the recommended land pattern for CSD25303W1015 according to TI's mechanical data?
Texas Instruments recommends a land pattern with 0.254 mm diameter solder paste openings, 0.50 mm pad pitch, and 0.86 mm center-to-center spacing between adjacent ball rows. The full pattern dimensions are 1.75 mm × 2.00 mm, matching the device's 1.0 × 1.5 mm body with 0.5 mm ball pitch and 6-ball array (A1, A2, B1, B2, C1, C2).
