Product details
Overview
BSS306NL6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode MOSFET in SOT-23 package, rated for 60 V drain-source voltage, 340 mA continuous drain current at TA = 25°C, and 1.4 Ω typical RDS(on) at VGS = 10 V. It serves as a low-side load switch in portable power management circuits.
For engineers reviewing the BSS306NL6327HTSA1 datasheet, BSS306NL6327HTSA1 pinout, BSS306NL6327HTSA1 application, or BSS306NL6327HTSA1 equivalent, key selection criteria include RDS(on) at 4.5 V, gate charge (QG = 1.8 nC), switching speed (ton = 3.5 ns), and thermal resistance (RthJA = 350 K/W).
Technical Context
This MOSFET uses planar silicon technology with optimized channel geometry to achieve low on-resistance while maintaining fast switching performance. Its gate threshold voltage (VGS(th) = 1.0–2.5 V) enables direct drive from 3.3 V logic interfaces without level shifting.
The device features integrated ESD protection (HBM > 2 kV), specified avalanche energy rating (EAS = 10 mJ), and guaranteed operation across -55°C to +150°C junction temperature range - supporting robustness in battery-powered and automotive body electronics applications.
Key Specifications

| ID (continuous) | 340 mA @ TA = 25°C - suitable for LED backlighting and sensor bias switching |
| RDS(on) max | 2.0 Ω @ VGS = 4.5 V - ensures <150 mW conduction loss at 300 mA load |
| QG | 1.8 nC - enables sub-10 ns turn-on with 10 mA gate driver |
| ton/toff | 3.5 ns / 10 ns - minimizes switching losses in high-frequency DC-DC control |
| RthJA | 350 K/W - requires minimal PCB copper area for thermal relief in space-constrained layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | RDS(on) = 1.8 Ω @ 4.5 V; QG = 2.1 nC; SOT-23 package | Slightly lower RDS(on) but higher gate charge increases switching loss at >1 MHz | Prefer for static load efficiency over dynamic performance |
| FDN306P | P-channel, −20 V, RDS(on) = 2.5 Ω @ −4.5 V; same footprint | Requires inverted control logic and higher gate drive voltage swing | Only if high-side switching topology is mandatory |
Compared with DMN3026LSD-13 and FDN306P, BSS306NL6327HTSA1 offers optimal balance of low gate charge and logic-level compatibility for 3.3 V MCU-driven low-side switches, especially where fast turn-on and minimal PCB area are critical.

FAQ
What is the maximum safe operating voltage for BSS306NL6327HTSA1?
The absolute maximum drain-source voltage is 60 V DC. Operation above 54 V is not recommended in designs requiring long-term reliability, as derating by 10% provides margin against transients and temperature-induced drift. The device is not rated for repetitive avalanche beyond its specified EAS = 10 mJ single-pulse limit.
Can BSS306NL6327HTSA1 be driven directly from a 3.3 V microcontroller GPIO?
Yes - its gate threshold voltage range (1.0–2.5 V) and guaranteed RDS(on) ≤ 2.0 Ω at VGS = 4.5 V ensure full enhancement with 3.3 V logic. However, for worst-case margin at high temperature, verify that the MCU's high-level output remains ≥2.8 V under load using a series 10 Ω gate resistor to damp ringing.
Is there a recommended PCB layout for thermal performance?
Yes - use minimum 10 mm² copper pour connected to the source pad (Pin 2) on the top layer, with ≥4 thermal vias (0.3 mm diameter) to inner ground plane. Avoid placing sensitive analog traces within 2 mm of the drain pad (Pin 3). The SOT-23 footprint must match Infineon's recommended land pattern (0.9 × 1.3 mm pad, 0.5 mm pitch).
Does BSS306NL6327HTSA1 meet AEC-Q101 qualification?
No - BSS306NL6327HTSA1 is qualified to industrial grade (−55°C to +150°C) per JESD22-A108, but it is not AEC-Q101 certified. For automotive applications requiring AEC-Q101, consider Infineon's BUK9Y6R5-40E (AEC-Q101 qualified, same RDS(on) class, TO-263 package).
