Product details
Overview
BSD235N L6327 from Infineon Technologies is a dual N-channel enhancement-mode MOSFET in PG-SOT-363 package, rated for 20 V VDS, 0.95 A continuous drain current, and 350 mΩ RDS(on) at VGS = 4.5 V; designed for low-voltage load switching in automotive body electronics and space-constrained consumer power management.
For engineers reviewing the BSD235N L6327 datasheet, BSD235N L6327 pinout, BSD235N L6327 application, or BSD235N L6327 equivalent, key selection criteria include its Super Logic-level gate drive (2.5 V rated), AEC-Q101 qualification, avalanche ruggedness, dual-channel integration in SOT-363, and 600 mΩ RDS(on) at 2.5 V gate voltage.
Technical Context
This dual N-channel MOSFET operates in enhancement mode with independent channel control, supporting discrete load switching where one transistor is active at a time per datasheet note. Its gate threshold voltage (0.7–1.2 V) enables reliable turn-on with low-voltage microcontrollers, while the integrated body diode supports bidirectional current paths in H-bridge pre-driver stages.
Thermal resistance of 250 K/W (junction-to-ambient, minimal footprint) and avalanche energy rating of 1.6 mJ define its transient robustness in inductive load switching. Dynamic parameters-including 49 pF Ciss, 3.6 ns rise time, and 0.32 nC total gate charge-support efficient high-frequency PWM operation up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 20 V - supports 12 V automotive and 5 V/3.3 V logic-supplied systems without derating |
| RDS(on) @ 4.5 V | 350 mΩ max - ensures <100 mW conduction loss at 0.95 A, enabling thermally constrained PCB layouts |
| RDS(on) @ 2.5 V | 600 mΩ max - guarantees functional switching down to 2.5 V logic levels, compatible with modern ultra-low-voltage MCUs |
| ID continuous | 0.95 A @ TA = 25 °C - suitable for LED drivers, sensor biasing, and small solenoid control |
| EAS | 1.6 mJ - provides single-pulse avalanche immunity during inductive load turn-off transients |
| Ciss | 49 pF typ - limits gate drive power requirement and enables fast switching with low-RG drivers |
| tr/tf | 3.6 ns / 1.2 ns - supports clean edge integrity in digital load control and PWM dimming applications |
Pinout & Package
Package: PG-SOT-363 (6-pin, dual-transistor, lead-free, halogen-free). Pin 1–3 and Pin 4–6 form two independent N-channel MOSFETs sharing source terminals (Pins 2 & 5) and drain terminals (Pins 1 & 4); gate terminals are Pins 3 and 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Drain 1 | High-side or low-side switch node for first channel; connects to load or supply rail |
| Pin 2 | Source 1 | Reference node for Channel 1; tied to ground or common return path |
| Pin 3 | Gate 1 | Logic-level control input for Channel 1; requires no level-shifting from 2.5 V MCU outputs |
| Pin 4 | Drain 2 | Independent switch node for second channel; enables dual-load control in same footprint |
| Pin 5 | Source 2 | Reference node for Channel 2; may be tied to Pin 2 or isolated per design |
| Pin 6 | Gate 2 | Separate logic-level control for Channel 2; supports asynchronous or complementary drive |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BSS138DW-7-F | Lower VDS (50 V), higher RDS(on) (3.5 Ω @ 2.5 V), no AEC-Q101 or avalanche rating | Suitable for non-automotive signal switching only; not rated for 12 V load switching or inductive energy absorption | Select when cost sensitivity outweighs automotive qualification and ruggedness requirements |
| DMN2023LSD-13 | Same VDS (20 V), lower RDS(on) (220 mΩ @ 4.5 V), but only 1.8 V logic-compatible-not AEC-Q101 qualified | Better efficiency in high-duty-cycle 3.3 V systems, but lacks automotive validation and transient robustness | Prefer for consumer-grade high-efficiency DC-DC biasing where qualification is not mandated |
Compared with BSS138DW-7-F and DMN2023LSD-13, BSD235N L6327 uniquely combines AEC-Q101 qualification, 2.5 V logic compatibility, and 1.6 mJ avalanche capability-making it the only option validated for safety-critical 12 V automotive load switching in compact SOT-363.

FAQ
Is BSD235N L6327 pin-compatible with standard SOT-363 dual MOSFETs like BSS138DW?
No. BSD235N L6327 uses a non-standard pin assignment: Pins 1/4 are drains, Pins 2/5 are sources, and Pins 3/6 are gates. BSS138DW assigns Pin 1/5 as gates and Pin 2/6 as drains-requiring PCB layout revision for substitution.
What is the maximum allowable gate-source voltage for continuous operation?
The absolute maximum VGS is ±12 V per datasheet. For reliable long-term operation, gate drive must remain within –10 V to +10 V; exceeding ±12 V risks irreversible oxide damage even for brief transients.
Does BSD235N L6327 support simultaneous conduction of both channels?
No. The datasheet explicitly states "only one of both transistors in operation" due to thermal coupling and SOA limitations. Concurrent use violates safe operating area constraints and voids AEC-Q101 compliance claims.
Can BSD235N L6327 replace mechanical relays in 12 V automotive circuits?
Yes-when used within its 0.95 A continuous and 3.8 A pulsed ratings, with proper PCB copper area for thermal dissipation. Its 1.6 mJ avalanche rating absorbs inductive kickback from solenoids and lamps, eliminating snubber networks required with non-avalanche MOSFETs.
