Product details

Overview

BSS169 E6327 from Infineon Technologies is an N-channel enhancement-mode MOSFET rated for 100 V V_DS, 170 mA continuous drain current, and 3.5 Ω R_DS(on) at V_GS = 10 V, used as a low-power load switch in battery-powered sensor nodes and signal routing circuits.

For engineers reviewing the BSS169 E6327 datasheet, BSS169 E6327 pinout, BSS169 E6327 application, or BSS169 E6327 equivalent, key selection criteria include its low gate threshold (V_GS(th) = 0.8–3.0 V), SOT23-3 package footprint, and guaranteed 100 V blocking capability under pulsed conditions.

Technical Context

This discrete MOSFET operates in enhancement mode with no inherent conduction at zero gate bias. Its transconductance (g_fs) is specified at 0.12 S, supporting precise analog switching control in low-current paths.

Designed for single-ended DC switching, it features a body diode with 1.2 V forward voltage and exhibits typical gate charge (Q_g) of 0.8 nC, enabling fast turn-on/turn-off in microcontroller-driven logic-level interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports operation across industrial 24 V and telecom 48 V supply rails without breakdown
I_D (continuous)	170 mA - suitable for driving LED indicators, small solenoids, or bias networks
R_DS(on)	3.5 Ω @ V_GS = 10 V - limits conduction loss to <0.1 W at 170 mA
V_GS(th)	0.8–3.0 V - enables direct drive from 1.8 V, 3.3 V, or 5 V GPIOs without level shifting
P_D	360 mW @ T_A = 25 °C - defines thermal derating limit in SOT23-3 without heatsink
C_iss	25 pF - minimizes capacitive loading on driving MCU pins during switching

Pinout & Package

Supplied in JEDEC-standard SOT23-3 plastic package with gull-wing leads, 1.3 mm pitch, and 1.3 mm × 2.9 mm footprint.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Receives logic-level voltage to modulate channel conduction; high-impedance node requiring minimal drive current
2 (Drain)	High-side switched output	Connected to load supply rail; blocks up to 100 V when off and conducts current when gate is asserted
3 (Source)	Reference return	Tied to system ground or low-side reference; establishes channel potential and carries full load current

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Operates fully enhanced from 3.3 V MCU outputs without external level shifters
Low gate charge	0.8 nC total gate charge enables <1 µs switching transitions with standard GPIO drivers
Specified avalanche energy rating	Rated for repetitive unclamped inductive switching (UIS) up to 10 mJ, enhancing robustness in relay/snubber-free designs
Qualified per AEC-Q101	Stress-tested for automotive temperature cycling, humidity, and mechanical shock per AEC-Q101 Rev D

Applications

Portable Sensor Node Power Gating

USB Port Overvoltage Protection

Use Scenario: Enables/disables power to MEMS accelerometers or environmental sensors during sleep cycles to extend battery life.

IC Role / Device Role / Timing Role: Low-leakage N-channel switch isolating V_CC rail; placed between battery and sensor VDD input.

Use Value: Achieves <100 nA off-state current, reducing quiescent draw below system RTC leakage.

Use Scenario: Blocks downstream circuitry from damage during USB VBUS overvoltage events (>6 V).

IC Role / Device Role / Timing Role: High-side protection switch controlled by USB controller fault signal.

Use Value: Withstands 100 V transient surges while limiting fault current via R_DS(on)-based current limiting.

Industrial I/O Module Signal Routing

Medical Wearable LED Indicator Control

Use Scenario: Routes 24 V DC signals between PLC inputs and field devices using optocoupler-isolated control.

IC Role / Device Role / Timing Role: Low-duty-cycle load switch toggling discrete 24 V outputs under microcontroller command.

Use Value: Delivers reliable 170 mA switching with <10 µs rise/fall times and no shoot-through risk.

Use Scenario: Drives status LEDs in compact wearable patches where board space and power budget are constrained.

IC Role / Device Role / Timing Role: Current-limiting switch in series with red/green LED anodes, driven directly from ARM Cortex-M0+ GPIO.

Use Value: Eliminates need for external current-setting resistors due to predictable R_DS(on) and low V_GS(th).

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-voltage N-channel switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP PMN20XNEA	R_DS(on) = 2.8 Ω @ V_GS = 4.5 V; lower threshold (0.5–1.5 V); same SOT23-3	Better suited for 1.8 V logic systems; slightly higher cost	Select when driving from sub-2.5 V controllers or requiring tighter V_GS(th) distribution
ON Semiconductor NSS10201LT1G	R_DS(on) = 4.5 Ω @ V_GS = 4.5 V; V_DS = 60 V; AEC-Q101 qualified	Limited to 60 V systems; lower price but reduced voltage margin	Prefer for cost-sensitive 24 V industrial controls where 100 V headroom is unnecessary

Compared with PMN20XNEA and NSS10201LT1G, BSS169 E6327 offers superior voltage margin (100 V) and tighter V_GS(th) consistency for mixed-supply systems, while maintaining SOT23-3 compatibility and AEC-Q101 qualification.

FAQ

Is BSS169 E6327 suitable for linear (analog) operation?

No. The BSS169 E6327 is characterized and qualified only for switching operation. Its Safe Operating Area (SOA) curve is not specified for linear mode, and prolonged operation in the ohmic region may cause thermal runaway due to positive temperature coefficient of R_DS(on).

What is the maximum allowable gate-source voltage?

The absolute maximum V_GS is ±20 V. Exceeding this risks permanent gate oxide damage. For reliable operation, gate drive should be limited to 10 V or less, especially in noisy environments where ringing could induce overshoot.

Does BSS169 E6327 have integrated ESD protection?

Yes. It includes on-chip HBM ESD protection rated to ±2 kV per JESD22-A114, sufficient for handling during PCB assembly but not for end-product interface-level ESD immunity.

Can BSS169 E6327 replace BS170 in existing designs?

Only with verification. While both are N-channel SOT23-3 MOSFETs, BSS169 has higher V_DS (100 V vs. 60 V) and lower I_D (170 mA vs. 500 mA). Layout and thermal design must be re-evaluated, particularly for loads exceeding 100 mA or requiring faster switching.
