Product details

Overview

BSP89L6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS small-signal transistor in PG-SOT223 package, rated for 240 V V_DS, 0.35 A continuous drain current, and 4.2–6 Ω R_DS(on) at V_GS = 10 V. It features dv/dt ruggedness up to 6 kV/µs and integrated body diode with 0.85–1.2 V forward voltage, suited for low-power switching in automotive lighting control and industrial sensor interface circuits.

For engineers reviewing the BSP89L6327HTSA1 datasheet, BSP89L6327HTSA1 pinout, BSP89L6327HTSA1 application, or BSP89L6327HTSA1 equivalent, this device is selected for logic-level gate drive compatibility, high dv/dt immunity in noisy environments, and thermal robustness in compact SMD layouts with minimal heatsinking.

Technical Context

This transistor operates as a single N-channel power switch optimized for low-voltage gate drive (V_GS(th) = 0.8–1.8 V) and fast switching (t_r = 3.5–5.3 ns, t_f = 18.4–27.6 ns). Its 6 kV/µs dv/dt rating enables reliable operation in inductive load commutation without spurious turn-on.

Thermal design is supported by R_thJS = 25 K/W (junction-to-soldering point, Pin 4) and R_thJA = 70 K/W on 6 cm² PCB copper area. The integrated body diode exhibits t_rr = 67–100 ns and Q_rr = 123–184 nC, enabling moderate-frequency freewheeling in flyback or half-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	240 V - supports 200 V DC bus applications with 20% margin
R_DS(on) @ 10 V	4.2–6 Ω - ensures <1.5 W conduction loss at 0.35 A
I_D cont @ 25°C	0.35 A - suitable for sub-1 W load switching
dv/dt rating	6 kV/µs - prevents false triggering in motor driver snubber circuits
V_GS(th)	0.8–1.8 V - fully enhanced by standard 3.3 V or 5 V logic outputs
t_r/t_f	3.5–5.3 ns / 18.4–27.6 ns - enables >1 MHz switching in low-duty-cycle PWM
Q_g	4.3–6.4 nC - compatible with low-current gate drivers (e.g., microcontroller GPIO)

Pinout & Package

Package: PG-SOT223 (4-pin variant, Pin 4 = Drain tab), surface-mount, lead-free, RoHS-compliant. Thermal path optimized via soldered drain tab (Pin 4) to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning

Pin 3	Drain (D)	High-side load connection; electrically tied to metal tab (Pin 4)
Pin 4	Drain Tab (D)	Primary thermal path to PCB; must be soldered for R_thJS = 25 K/W performance

Key Features

Feature	Design Value

Integrated body diode	Low V_SD (0.85–1.2 V) and controlled Q_rr enable efficient freewheeling
AEC-Q101 qualified	Validated for automotive applications including interior lighting and sensor biasing
Thermal efficiency	25 K/W junction-to-tab resistance allows operation at 150°C junction temperature with minimal copper area

Applications

Automotive LED Headlamp Dimming

IC Role / Device Role / Timing Role: Precision current source switch enabling 10–100 mA sensor excitation with <1 µs response to enable/disable commands.

Use Value: Low V_GS(th) tolerance (±0.2 V) ensures reliable turn-on across wide temperature range; integrated diode absorbs inductive kickback without external clamp.

Smart Home Relay Driver

Medical Patient Monitor Power Sequencing

Use Scenario: Solid-state replacement for electromechanical relays in smart outlet and HVAC control units.

IC Role / Device Role / Timing Role: High-voltage isolation switch driving 24 V AC/DC relay coils; withstands 240 V transient surges per IEC 61000-4-5.

Use Value: 240 V V_DS rating provides 2× safety margin over 120 VAC mains; low Q_g minimizes MCU GPIO loading during frequent switching cycles.

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
BSP89H6327XTSA1	Same die, tape-and-reel packaging (2500 pcs/reel vs. 1000 pcs); identical electrical specs	No functional difference; used where higher reel quantity reduces handling cost	Select when procurement volume justifies larger reels and line changeover time is minimized
BSL307N03AD	Lower V_DS (30 V), lower R_DS(on) (2.8 mΩ), higher I_D (30 A), SO-8 package	Not suitable for 200+ V applications; requires PCB redesign due to different footprint and thermal path	Choose only for low-voltage, high-current designs where 240 V rating is unnecessary

Compared with BSP89H6327XTSA1, the L6327 variant offers tighter logistics control for low-volume builds; versus BSL307N03AD, it trades current capacity for high-voltage resilience and SOT223 space efficiency-critical in constrained automotive ECUs.

FAQ

What is the maximum safe operating voltage for BSP89L6327HTSA1 in continuous DC applications?

The absolute maximum drain-source voltage is 240 V DC, verified per datasheet Rev. 2.1. Operation above 200 V DC is permitted only with derating per the Safe Operating Area (SOA) curve on Page 3, and requires verification of peak transient suppression in the target circuit to avoid avalanche breakdown.

Can BSP89L6327HTSA1 be driven directly from a 3.3 V microcontroller GPIO?

Yes. With V_GS(th) ranging from 0.8 V to 1.8 V and gate plateau voltage at 3.1 V, the device achieves full enhancement at 3.3 V. Measured R_DS(on) at V_GS = 3.3 V is ≤12 Ω (typical), sufficient for ≤100 mA loads; for 0.35 A operation, 4.5 V or higher is recommended.

Is the drain tab (Pin 4) electrically isolated from other pins?

No. Pin 4 is the exposed drain metallization and is electrically connected to Pin 3 (Drain). It must be soldered to a PCB copper pour serving as both thermal sink and high-current return path. Electrical isolation requires insulating thermal pad material or mechanical standoff.

Does BSP89L6327HTSA1 include built-in ESD protection?

Yes. It is rated Class 1A per JESD22-A114-HBM with ESD withstand capability >250 V and <500 V. This protects against typical handling electrostatic discharge but does not replace system-level ESD design (e.g., TVS diodes on signal lines).
