Product details

Overview

BSL303SPEH6327XTSA1 from Infineon Technologies is a P-channel enhancement-mode MOSFET in PG-TSOP-6 package, rated for -30 V V_DS, 6.3 A continuous drain current at T_A = 25 °C, and 33 mΩ R_DS(on) at V_GS = -10 V. It serves as a logic-level power switch in low-side load control circuits for industrial power management and automotive body electronics.

For engineers reviewing the BSL303SPEH6327XTSA1 datasheet, BSL303SPEH6327XTSA1 pinout, BSL303SPEH6327XTSA1 application, or BSL303SPEH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, -4.5 V logic-level gate drive compatibility, avalanche energy rating of 30 mJ, and ESD protection per JESD22-A114 Class HBM Level 2.

Technical Context

This OptiMOS™-P3 device uses trench-gate silicon technology optimized for low R_DS(on) × Q_g figure-of-merit in compact SMD packages. Its gate threshold voltage range (-2.0 to -1.5 V) ensures reliable turn-on with standard 3.3 V/5 V logic drivers while maintaining robustness against false triggering.

Dynamic parameters-including 14.0–20.9 nC total gate charge, 33–49 ns reverse recovery time, and 1053–1401 pF input capacitance-are characterized under defined test conditions (V_DD = -15 V, I_D = -6.3 A, R_G,ext = 6 Ω) and support fast switching in DC-DC converters and motor driver half-bridges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-30 V - Maximum blocking voltage in reverse-polarity applications
R_DS(on) @ V_GS = -10 V	33 mΩ max - Enables ≤0.13 W conduction loss at 6.3 A
I_D continuous	-6.3 A @ T_A = 25 °C - Supports high-current load switching on minimal PCB copper area
E_AS	30.0 mJ - Withstands single-pulse inductive energy without failure
Q_g	14.0–20.9 nC - Determines gate driver power requirement and switching speed trade-off
V_GS(th)	-2.0 to -1.5 V - Ensures full enhancement with 3.3 V logic-level gate drive
t_r/t_f	7.7–12 ns / 8.3–12 ns - Supports >10 MHz PWM operation in synchronous buck stages

FAQ

What is the maximum allowable gate-source voltage for BSL303SPEH6327XTSA1?

The absolute maximum V_GS is ±20 V, as specified in the datasheet's "Maximum ratings" table. Exceeding this limit risks permanent gate oxide damage. For reliable operation, gate drive should be clamped to -12 V maximum in negative swing applications, especially during hot-plug or transient events.

Does BSL303SPEH6327XTSA1 require a gate resistor for typical 3.3 V MCU drive?

Yes-a 10–47 Ω series gate resistor is recommended to dampen ringing and limit peak gate current during switching. The device's 14–21 nC total gate charge and low input capacitance make it sensitive to parasitic oscillation without controlled gate impedance, particularly in layouts with >5 cm trace length.

How does the PG-TSOP-6 package affect thermal performance compared to SO-8?

PG-TSOP-6 offers lower R_thJA (62.5 K/W with 6 cm² copper) than standard SO-8 (typically >80 K/W), due to its exposed drain pad and thinner profile. This enables 1.8× higher power density in constrained spaces but requires strict adherence to solder paste volume and reflow profile to ensure void-free thermal interface to the PCB.

Is the reverse diode in BSL303SPEH6327XTSA1 suitable for synchronous rectification?

No-the integrated body diode has 33–49 ns reverse recovery time and 28–43 nC Q_rr, making it unsuitable for high-frequency synchronous rectification above 100 kHz. It is designed for freewheeling and protection, not active conduction; external Schottky or GaN FETs are required for true synchronous operation.
