Product details
Overview
PSMNR98-25YLE from Nexperia is an N-channel enhancement-mode ASFET in LFPAK56 (SOT669) package, optimized for hot-swap, inrush current limiting, and linear-mode operation with 25 V VDS, 1.11 mΩ RDS(on) at VGS = 10 V / Tj = 25 °C, and 192 W Ptot at Tmb = 25 °C - deployed in 12–20 V e-fuse and load-switch modules.
For engineers reviewing the PSMNR98-25YLE datasheet, PSMNR98-25YLE pinout, PSMNR98-25YLE application, or PSMNR98-25YLE equivalent, key selection criteria include SOA robustness in linear mode, low RDS(on) stability over temperature, gate charge profile for fast switching control, and mounting-base thermal resistance for high-current PCB designs.
Technical Context
This device employs a copper-clip LFPAK56 construction to minimize parasitic inductance and junction-to-mounting-base thermal resistance (Rth(j-mb) = 0.45 K/W typ), enabling stable operation under sustained linear-mode stress. Its enhanced SOA supports unclamped avalanche energy of 1.3 J and peak drain current up to 1259 A (10 µs pulse).
The gate threshold voltage (VGS(th) = 1.94 V typ) and low gate leakage (<100 nA) support precise gate drive in high-side load switch configurations. Soft reverse-recovery diode behavior (S = 1.03) and low QGD (8 nC typ) reduce switching losses and EMI during turn-off transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 25 V maximum - defines absolute upper rail voltage for 12–20 V hot-swap systems without derating |
| RDS(on) | 0.94–1.11 mΩ at VGS = 10 V / Tj = 25 °C - enables <1.5 W conduction loss at 25 A, critical for thermally constrained e-fuse PCBs |
| ID | 255 A continuous (Tmb = 25 °C) - validated current capability exceeds typical 100–200 A board-level fusing requirements |
| QG(tot) | 27 nC typ at VGS = 10 V - determines gate driver power and switching speed in active current-limit circuits |
| Rth(j-mb) | 0.45 K/W typ - allows direct thermal coupling to heatsink or copper plane, enabling >150 A steady-state operation with proper board layout |
| VGS(th) | 1.2–2.2 V - ensures reliable turn-on with standard 3.3 V or 5 V logic-level gate drivers |
| SOA Energy | 1.3 J unclamped avalanche - provides fault tolerance during short-circuit events without external snubbers |
Pinout & Package
LFPAK56 (SOT669) is a 4-terminal surface-mount package with exposed mounting base connected to drain, offering 30 mm² footprint, copper-clip construction, and qualification to 175 °C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three parallel source terminals reduce bond-wire inductance and improve current sharing in high-di/dt hot-swap transients |
| 4 | Gate (G) | Single gate input with 3.1 Ω typical gate resistance - compatible with standard MOSFET drivers without external gate resistors |
| Mounting Base (mb) | Drain (D) | Exposed copper pad electrically and thermally connected to drain - serves as primary current path and thermal interface to PCB |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced SOA for linear mode | Validated 1.3 J unclamped avalanche energy and 1259 A pulsed current - enables safe operation during inrush and overload without thermal runaway |
| Low RDS(on) stability | RDS(on) increases only 2× from 25 °C to 150 °C - maintains predictable conduction loss across industrial temperature range |
| Copper-clip LFPAK56 | 0.45 K/W Rth(j-mb) and <1 µA IDSS at 125 °C - delivers superior thermal performance and leakage control vs. wire-bonded SO-8 |
| Soft-recovery body diode | S = 1.03 - minimizes voltage overshoot and EMI during reverse recovery in bidirectional load-switch applications |
| High-reliability qualification | 175 °C junction rating and 260 °C peak soldering tolerance - supports automotive-grade assembly and long-life industrial deployments |
Applications

IC Role / Device Role / Timing Role: Bidirectional blocking element with reverse-polarity and short-circuit protection. Use Value: Low VSD (0.79 V typ) and soft diode recovery minimize forward conduction loss and voltage spikes during battery disconnect events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hot-swap and e-fuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BSC014N04LS6 | 40 V VDS, 1.4 mΩ RDS(on), PG-HSOF-8 package, higher QG (36 nC) | Wider voltage margin but lower current density and inferior SOA linearity | Choose when 40 V headroom is required and thermal constraints allow larger footprint |
| Vishay SiR626DP | 30 V VDS, 1.25 mΩ RDS(on), PowerPAK SO-8, no avalanche rating published | Limited SOA validation data; not qualified for unclamped inductive switching | Prefer only in non-fault-tolerant linear-mode use cases where avalanche immunity is not required |
Compared with BSC014N04LS6 and SiR626DP, PSMNR98-25YLE offers the lowest RDS(on) per mm², highest validated avalanche energy, and most robust SOA curve - making it optimal for compact, high-reliability hot-swap modules demanding guaranteed linear-mode survivability.

FAQ
What is the maximum continuous drain current rating for PSMNR98-25YLE?
The device is rated for 255 A continuous drain current at Tmb = 25 °C, as verified in application testing. Real-world current capability depends on PCB copper area, thermal interface, and ambient conditions - with 223 A supported at Tmb = 100 °C per Fig. 2 of the datasheet.
Does PSMNR98-25YLE require a gate resistor for safe operation?
No external gate resistor is required for basic switching, as its typical gate resistance is 3.1 Ω and total gate charge is 27 nC at 10 V. However, a small series resistor (1–5 Ω) is recommended to dampen ringing in high-di/dt hot-swap gate-drive loops with long traces.
How is the mounting base (mb) electrically connected in PSMNR98-25YLE?
The mounting base is internally connected to the drain terminal and forms the primary current and thermal path. It must be soldered to a large copper pour or heatsink; electrical isolation from other planes is required unless drain-referenced topology is intended.
Can PSMNR98-25YLE be used in bidirectional current applications?
Yes - its source-drain diode has soft reverse recovery (S = 1.03) and 192 A continuous forward current rating. It supports bidirectional blocking and controlled turn-off in battery protection circuits, though body diode conduction should be minimized via synchronous gate control where possible.
