Components such as the CSD17301Q5A or CSD17302Q5A offer tightly matched logic-level gate drives and robust thermal ratings. 30V, N-Channel NexFet Power MOSFETs datasheet (Rev. C)
Housed in a larger, thermally superior DFN5x6 (PRPAK5x6) footprint. C) Housed in a larger, thermally superior DFN5x6
If the original UBIQ component is out of stock, several industry-standard 30V N-Channel MOSFETs match the pinout and electrical constraints. For the 5x6mm (M6) Footprint:
You don’t need a $50,000 curve tracer. Here’s a practical verification routine using common bench equipment.
| Alternative Part | Package | Key Difference | |----------------|---------|----------------| | | SOT-23 | Lower ( R_DS(on) ) (30mΩ max), similar V_GS(th) | | SI2302 | SOT-23 | Slightly higher current rating (3.5A) | | IRLML2502 | SOT-23 | Enhanced ESD protection, logic level | | DMN2040U | SOT-23 | 20V V_DS, lower capacitance for high-speed switching | | 2N7002 | SOT-23 | Caution: Lower current (300mA) – not a direct substitute for high-power use |
: It is optimized for fast switching and low power losses, making it a "go-to" for compact, high-density power modules . Typical Applications
