Product details
Overview
BSL373SNH6327XTSA1 from Infineon Technologies is an N-channel enhancement-mode MOSFET in TSOP6 package, rated for 100 V VDS, 2.0 A continuous drain current, and 0.23 Ω max RDS(on) at VGS = 10 V. It is AEC-Q101 qualified, avalanche-rated, and optimized for industrial DC-DC converters and motor control stages requiring robust switching under repetitive transient stress.
For engineers reviewing the BSL373SNH6327XTSA1 datasheet, BSL373SNH6327XTSA1 pinout, BSL373SNH6327XTSA1 application, or BSL373SNH6327XTSA1 equivalent, key selection criteria include its 33 mJ single-pulse avalanche energy, 6 kV/µs di/dt ruggedness, 2.1–4.0 V gate threshold range, and TSOP6 thermal resistance of 62.5 K/W with 6 cm² copper area.
Technical Context
This OptiMOS™ small-signal transistor uses a trench-based silicon process to achieve low RDS(on) while maintaining high dv/dt immunity and controlled gate charge (Qg = 6.2–9.3 nC). Its integrated body diode features 27–41 ns reverse recovery time and 60–90 nC Qrr, enabling efficient synchronous rectification in flyback and buck topologies.
The device operates across –55 °C to +150 °C junction temperature, with thermal resistance junction-to-ambient of 62.5 K/W on a 6 cm² PCB copper area. Gate threshold voltage shifts predictably with temperature (2.1 V min at 25 °C, 1.2 V typ at 150 °C), supporting stable biasing in thermally varying environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports input rails up to 80 V DC with margin for transients in industrial power supplies |
| RDS(on) max | 230 mΩ at VGS = 10 V, ID = 2 A - enables <1.0 W conduction loss at full load in 2 A switch-node applications |
| ID continuous | 2.0 A at TA = 25 °C - suitable for compact 5–15 W isolated DC-DC stages without forced air |
| EAS | 33 mJ - withstands single inductive turn-off events up to 2 A with 25 Ω gate resistor |
| Qg | 6.2–9.3 nC - determines gate drive power requirement and switching speed in 100–500 kHz SMPS designs |
| tr/tf | 5.9–8.9 ns / 13.6–20.4 ns - enables fast transitions with minimal overlap loss in hard-switched topologies |
| VGS(th) | 2.1–4.0 V - ensures reliable turn-on with standard 3.3 V or 5 V logic-level drivers |
Pinout & Package
BSL373SNH6327XTSA1 is housed in a surface-mount TSOP6 package (4.9 mm × 2.8 mm × 1.1 mm), featuring exposed drain pad for enhanced thermal dissipation and optimized for automated placement on FR4 PCBs with minimal footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Power return path for channel current | Internally connected to substrate; requires low-impedance ground plane routing |
| 2 (Gate) | Control electrode for channel modulation | High-impedance input; sensitive to ESD (Class HBM 0); needs local RC snubber for ringing suppression |
| 3 (Drain) | Main current-carrying terminal | Exposed pad (pins 4–6) - must be soldered to ≥6 cm² copper pour for thermal performance |
| 4 (Drain) | Drain connection (common with pins 5 & 6) | Part of multi-pin drain structure to reduce package inductance and improve current sharing |
| 5 (Drain) | Drain connection (common with pins 4 & 6) | Enables symmetric layout for balanced thermal distribution and reduced parasitic loop area |
| 6 (Drain) | Drain connection (common with pins 4 & 5) | Supports high-current pulse handling (ID,pulse = 8.0 A) when all three pins are properly routed |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated operation | Guaranteed 33 mJ single-pulse energy handling without degradation - eliminates need for external clamping in inductive loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP3NK100Z | 1000 V VDS, 2.5 A ID, 5.5 Ω RDS(on) - higher voltage rating but significantly higher on-resistance | Targeted at high-voltage AC-DC PFC stages, not low-loss DC-DC or motor control | Select only if >600 V blocking capability is required; unsuitable for efficiency-critical 24–48 V systems |
| DMN3028LSD-13 | 30 V VDS, 6.5 A ID, 28 mΩ RDS(on) - lower voltage, higher current, much lower RDS(on) | Optimized for 5–12 V load switching and battery protection, not 100 V industrial transients | Prefer for portable electronics or USB-PD sinks; avoid where 100 V surge immunity is mandatory |
Compared with STP3NK100Z and DMN3028LSD-13, BSL373SNH6327XTSA1 uniquely balances 100 V rating, 230 mΩ RDS(on), and AEC-Q101 qualification - making it the only option among the three validated for thermally demanding, transient-rich 24–48 V industrial motor and power supply designs.

FAQ
What is the maximum allowable gate-source voltage for BSL373SNH6327XTSA1?
The absolute maximum gate-source voltage is ±20 V. Operation beyond this risks permanent oxide damage. For reliable switching, gate drive should be limited to 10–12 V for optimal RDS(on) and safe margin against overshoot. The device's VGS(th) range (2.1–4.0 V) ensures turn-on with 3.3 V logic, but full enhancement requires ≥10 V.
Does BSL373SNH6327XTSA1 require a gate resistor, and what value is recommended?
Yes - a gate resistor is essential to control dV/dt, suppress oscillation, and limit peak gate current. For 500 kHz operation with a 1-A peak gate driver, a 6.8 Ω series resistor is recommended based on Qg = 7.8 nC typical and tr/tf targets. Lower values increase switching speed but risk ringing; higher values reduce EMI at the cost of increased switching loss.
Can BSL373SNH6327XTSA1 be used in parallel configurations?
Yes, but only with careful layout and gate drive design. Its positive RDS(on) temperature coefficient (RDS(on) increases with Tj) enables inherent current sharing. To ensure balance, use matched gate resistors, symmetrical PCB traces, and shared thermal mass. Avoid paralleling more than two devices without individual current sensing due to parametric spread in VGS(th).
Is the TSOP6 package lead-free and compatible with standard reflow profiles?
Yes - BSL373SNH6327XTSA1 is RoHS-compliant and halogen-free, with lead-free terminations qualified for IPC/JEDEC J-STD-020D reflow. Peak temperature is rated at 260 °C for ≤10 seconds. The exposed drain pad requires full solder coverage to meet thermal specs; voiding >25% degrades RthJA by up to 30%.
