Product details

Overview

BSS214NL6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode MOSFET optimized for logic-level gate drive at 2.5 V, with 20 V V_DS, 1.5 A continuous drain current, 140 mΩ R_DS(on) at V_GS = 4.5 V, and AEC-Q101 qualification for automotive signal switching in body control modules and LED drivers.

For engineers reviewing the BSS214NL6327HTSA1 datasheet, BSS214NL6327HTSA1 pinout, BSS214NL6327HTSA1 application, or BSS214NL6327HTSA1 equivalent, key selection criteria include super logic-level threshold (V_GS(th) max 1.2 V), avalanche ruggedness (E_AS = 3.7 mJ), SOT-23 package thermal resistance (R_thJA = 250 K/W), and reverse diode recovery (t_rr = 8.4 ns).

Technical Context

This OptiMOS™2 small-signal transistor uses trench-gate technology to achieve low R_DS(on) at 2.5 V gate drive while maintaining robust avalanche capability. Its 0.7–1.2 V gate threshold enables reliable turn-on with 3.3 V or lower microcontroller I/O.

Dynamic parameters include C_iss = 143 pF, C_oss = 62 pF, and Q_g = 0.8 nC, supporting fast switching in low-power DC-DC load switches and PWM-controlled loads up to 1 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	20 V - Maximum blocking voltage for 12 V automotive and industrial supply rails
R_DS(on) @ V_GS=4.5 V	140 mΩ - Enables <150 mW conduction loss at 1.5 A, suitable for thermally constrained PCBs
V_GS(th)	0.7–1.2 V - Ensures full enhancement with 2.5 V logic, eliminating need for level shifters
I_D continuous	1.5 A @ T_A=25 °C - Supports typical LED string or solenoid driver loads without heatsinking
E_AS	3.7 mJ - Withstands inductive kickback from relay coils and motor windings without failure
t_rr	8.4 ns - Minimizes switching losses and cross-conduction risk in synchronous rectifier or half-bridge topologies
C_iss	143 pF - Low input capacitance reduces gate drive power and improves high-frequency response

FAQ

What is the maximum junction temperature for continuous operation?

The BSS214NL6327HTSA1 has a specified operating junction temperature range of −55 °C to +150 °C. Continuous operation at T_j = 150 °C is permitted per its Safe Operating Area (SOA) curves, provided ambient conditions and PCB thermal design maintain R_thJA ≤ 250 K/W on the defined 40 mm² FR4 test board.

Is this MOSFET suitable for driving inductive loads without external protection?

Yes-the device is avalanche rated with E_AS = 3.7 mJ at I_D = 1.5 A and R_GS = 25 Ω, enabling it to absorb energy from unclamped inductive flyback in applications like relay or solenoid drivers without external snubbers, provided pulse duration and repetition rate stay within SOA limits.

Does the SOT-23 package support reflow soldering per JEDEC standards?

Yes-the BSS214NL6327HTSA1 is qualified for lead-free reflow soldering at peak temperatures up to 260 °C per J-STD-020, with halogen-free molding compound compliant to IEC61249-2-21, and is supplied in dry-packed tape-and-reel format (H6327, 3000 pcs/reel).

How does the gate threshold voltage vary over temperature?

V_GS(th) decreases linearly with rising junction temperature, ranging from ~1.2 V at −55 °C to ~0.4 V at +150 °C (typical curve on page 6 of Rev 2.3 datasheet), ensuring consistent turn-on behavior across the full AEC-Q101 temperature range without requiring gate bias adjustment.
