Product details

Overview

BSP318S E6327 from Infineon Technologies is an N-channel enhancement-mode SIPMOS™ small-signal MOSFET rated for 60 V drain-source voltage, 2.6 A continuous drain current, and 0.09 Ω R_DS(on) at V_GS = 10 V - designed for logic-level gate drive in low-power switching applications such as LED drivers and load switches in automotive body electronics.

For engineers reviewing the BSP318S E6327 datasheet, BSP318S E6327 pinout, BSP318S E6327 application, or BSP318S E6327 equivalent, key selection criteria include avalanche energy rating (60 mJ), dv/dt ruggedness (6 kV/µs), reverse diode forward voltage (0.95 V at 5.2 A), and AEC-Q101 qualification for automotive use.

Technical Context

This MOSFET employs a trench-based SIPMOS process enabling low on-resistance with fast switching (t_r = 15–25 ns, t_f = 15–25 ns) and robust unclamped inductive switching capability. Its gate threshold voltage (1.2–2.0 V) ensures reliable turn-on with 3.3 V or 5 V logic controllers.

The integrated body diode supports bidirectional current flow in H-bridge or flyback configurations, with measured reverse recovery time of 50–75 ns and Q_rr = 0.1–0.15 µC - critical for minimizing switching losses in high-frequency DC-DC converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage for 12 V/24 V automotive and industrial supply rails
R_DS(on) @ V_GS=10 V	0.09 Ω - enables <150 mW conduction loss at 2.6 A, reducing thermal stress on SOT-223 PCB footprint
I_D (continuous)	2.6 A - supports medium-current loads like solenoid drivers and fan controllers without heatsinking
E_AS	60 mJ - withstands single-pulse inductive energy in relay or motor coil snubbing
dv/dt rating	6 kV/µs - prevents false turn-on during fast transient noise in automotive CAN/LIN subsystems
V_GS(th)	1.2–2.0 V - compatible with 3.3 V microcontroller GPIO without level-shifting circuitry
Q_g (total)	14 nC - determines gate driver current requirement (~1.4 mA avg. for 100 kHz switching)

Pinout & Package

Package: PG-SOT223 (standard SOT-223-4L with exposed drain pad), lead-free and RoHS compliant, qualified per AEC-Q101.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate (G)	Control input; requires ≤±20 V bias; low input capacitance (C_iss = 300–380 pF) eases driving
Pins 2 & 4	Drain (D)	Main power path output; electrically connected to exposed copper pad for thermal conduction to PCB
Pin 3	Source (S)	Reference node for gate drive and current sensing; tied to ground or low-side shunt in typical configurations

Key Features

Feature	Design Value
Avalanche rated	Single-pulse E_AS = 60 mJ - eliminates need for external clamping in inductive load switching
Logic-level gate	V_GS(th) max = 2.0 V - enables direct interface with 3.3 V MCU outputs without gate driver IC
dv/dt ruggedness	6 kV/µs - suppresses parasitic turn-on in noisy environments (e.g., engine control modules)
Reverse diode integration	V_SD = 0.95 V @ 5.2 A - supports freewheeling in half-bridge topologies without discrete diode

Applications

Industrial LED Driver

Use Scenario: Switching 12 V incandescent and LED lamps in door modules and interior lighting.

IC Role / Device Role / Timing Role: Low-side load switch controlling lamp current up to 2.6 A with PWM dimming.

IC Role / Device Role / Timing Role: Back-to-back configured MOSFET for ideal diode functionality.

Use Value: Low V_GS(th) and R_DS(on) reduce forward voltage drop to <300 mV at 2 A, improving efficiency vs. Schottky diodes.

Use Scenario: Bidirectional control of 12 V brushed DC motors in HVAC actuators and seat adjusters.

IC Role / Device Role / Timing Role: Half-bridge low-side switch paired with complementary high-side device.

Use Value: Integrated body diode with t_rr < 75 ns limits voltage spikes during commutation, reducing EMI filter burden.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3025LSD-13	R_DS(on) = 0.025 Ω @ 4.5 V (lower), but V_DS = 30 V (reduced voltage margin)	Suitable only for ≤24 V systems; higher current capability (4.5 A) trades off voltage headroom	Select when lower conduction loss is prioritized over 60 V surge tolerance
IPB032N06L3	TO-263 package, R_DS(on) = 0.032 Ω @ 10 V, higher P_tot = 100 W - not pin-compatible	Requires PCB redesign; intended for high-power (>10 A) applications with heatsink	Choose only when thermal budget exceeds SOT-223 limits and board space allows TO-263 mounting

Compared with DMN3025LSD-13 and IPB032N06L3, the BSP318S E6327 uniquely balances 60 V rating, logic-level drive, AEC-Q101 compliance, and SOT-223 manufacturability - making it optimal for cost-sensitive, space-constrained automotive and industrial switching where voltage margin and qualification matter more than ultra-low R_DS(on).

FAQ

Is BSP318S E6327 suitable for 3.3 V microcontroller gate drive?

Yes. With a gate threshold voltage range of 1.2–2.0 V and guaranteed turn-on at V_GS = 4.5 V, the BSP318S E6327 fully supports direct drive from 3.3 V GPIOs. Its low input capacitance (C_iss ≤ 380 pF) further reduces required gate charge, minimizing driver loading and propagation delay.

What is the thermal resistance from junction to soldering point (R_thJS)?

The datasheet specifies R_thJS = 17 K/W (max) from junction to soldering point (Pin 4). This value assumes proper soldering of the exposed drain pad to ≥6 cm² copper area on FR4 PCB - enabling 1.8 W power dissipation at T_A = 25 °C without forced airflow.

Does BSP318S E6327 have a built-in body diode, and what are its characteristics?

Yes. It integrates a fast, low-V_F body diode rated for 2.6 A continuous forward current (I_S) and 10.4 A pulsed (I_SM). At 5.2 A, V_SD is 0.95 V (typ), with t_rr = 50–75 ns and Q_rr = 0.1–0.15 µC - suitable for freewheeling in synchronous rectification and H-bridge motor control.

How does the avalanche rating impact system design?

The 60 mJ single-pulse avalanche energy rating (E_AS) allows the device to safely absorb inductive kickback without external snubbers in applications like relay or solenoid driving. This simplifies PCB layout, reduces BOM count, and improves reliability under worst-case switching conditions where V_DS may exceed 60 V momentarily.
