Product details
Overview
BSP372L6327HTSA1 from Infineon Technologies is an N-channel logic-level SIPMOS® small-signal power MOSFET in PG-SOT223 package, rated for 100 V VDS, 1.7 A continuous drain current, and 0.31 Ω RDS(on) at VGS = 5 V. It features avalanche-rated ruggedness, ±14 V gate-source voltage rating, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BSP372L6327HTSA1 datasheet, BSP372L6327HTSA1 pinout, BSP372L6327HTSA1 application, or BSP372L6327HTSA1 equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 0.8–2.0 V), low RDS(on) at 5 V, integrated body diode with trr = 65 ns, and thermal resistance RthJA ≤ 70 K/W on standard PCB layout.
Technical Context
This device operates in enhancement mode with a threshold voltage range of 0.8–2.0 V, enabling direct drive from 3.3 V or 5 V microcontrollers without level-shifting. Its SIPMOS® process delivers low gate charge and fast switching: td(on) = 20–30 ns, tr = 35–55 ns, and Ciss = 415–520 pF at 25 V.
The integrated body diode supports bidirectional current flow with VSD = 0.85–1.1 V at IF = 1.7 A and reverse recovery charge Qrr = 0.11 μC, making it suitable for flyback, buck, and half-bridge topologies requiring controlled commutation.
Key Specifications

|---|---|
| VDS | 100 V - supports 24 V and 48 V industrial bus systems with margin against transients |
| ID (continuous) | 1.7 A at TA = 28 °C - enables compact load switching up to ~20 W with minimal heatsinking |
| RDS(on) | 0.24–0.31 Ω at VGS = 5 V - ensures <1 W conduction loss at full current under logic-level drive |
| VGS(th) | 0.8–2.0 V - guarantees turn-on with 3.3 V GPIOs and robust noise immunity |
| EAS | 45 mJ at Tj = 25 °C - provides single-pulse avalanche energy handling for inductive load interruption |
| Ciss | 415–520 pF - limits gate drive power requirement and enables >1 MHz switching in optimized layouts |
| trr | 65 ns - reduces switching losses and EMI in synchronous rectification and PWM control |
Pinout & Package

| Pin 2 | Drain (D) | Main high-side or low-side current path; connected to exposed pad for thermal conduction |
| Pin 3 | Source (S) | Reference node for gate drive and current sensing; ties to ground or low-side return path |
| Pin 4 | Drain (D) | Second drain terminal-paralleled with Pin 2 to halve effective bondwire inductance and improve SOA |

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 |
|---|---|---|---|
| STP1NK60Z | 600 V VDS, higher RDS(on) (12 Ω), not logic-level (VGS(th) = 2–4 V) | Designed for high-voltage SMPS primary side, not low-voltage load switching | Select only if higher breakdown voltage is required and gate drive can support ≥4 V threshold |
| DMN3025LFG-7 | 30 V VDS, lower RDS(on) (22 mΩ), same logic-level drive (VGS(th) = 0.5–1.2 V) | Optimized for 5–12 V consumer power rails; insufficient for 24 V+ industrial transients | Prefer for 3.3/5 V embedded systems where VDS ≤ 30 V suffices and ultra-low RDS(on) is critical |
Compared with STP1NK60Z and DMN3025LFG-7, BSP372L6327HTSA1 uniquely balances 100 V capability, logic-level drive, and automotive qualification-making it optimal for 24 V/48 V automotive and industrial load switches where both voltage margin and MCU compatibility are essential.

FAQ
Is BSP372L6327HTSA1 suitable for 3.3 V microcontroller gate drive?
Yes. With VGS(th) ranging from 0.8 V to 2.0 V and guaranteed RDS(on) ≤ 0.31 Ω at VGS = 5 V, it achieves full enhancement using standard 3.3 V GPIOs. Measured gfs = 3.7 S at ID = 1.7 A confirms strong transconductance under low-voltage bias.
What is the maximum safe operating junction temperature?
The absolute maximum junction temperature is +150 °C, validated per AEC-Q101 stress testing. Derating curves show Ptot drops linearly above 25 °C ambient, reaching 0 W at 120 °C on standard PCB - consistent with RthJA ≤ 70 K/W specification.
Does this MOSFET include an integrated body diode?
Yes. The device integrates a monolithic body diode with VSD = 0.85–1.1 V at IF = 1.7 A and trr = 65 ns at diF/dt = 100 A/μs. This enables freewheeling in buck converters and inductive load driving without external diodes.
How does avalanche rating impact real-world reliability?
EAS = 45 mJ at Tj = 25 °C means the device withstands one 25 V, 1.7 A inductive energy pulse without failure. This protects against relay coil collapse, motor stall events, and cable disconnect transients in automotive and industrial environments.
