Product details
Overview
BSP171PE6327T from Infineon Technologies is a P-channel enhancement-mode SIPMOS® small-signal MOSFET in PG-SOT223 package, rated for -60 V VBR(DSS), 0.21 Ω RDS(on) at VGS = -10 V and ID = -1.9 A, avalanche-rated, and qualified to AEC-Q101 for automotive use. It serves as a logic-level load switch in low-power DC-DC converters and LED drivers.
For engineers reviewing the BSP171PE6327T datasheet, BSP171PE6327T pinout, BSP171PE6327T application, or BSP171PE6327T equivalent, key selection criteria include its -1.5 V gate threshold voltage, 1.4–2.7 S transconductance, -1.9 A continuous drain current, and robust dv/dt rating of 1 kV/µs under specified conditions.
Technical Context
This device operates in enhancement mode with a negative gate threshold (VGS(th) = -1 to -2 V), requiring active pull-down for turn-on in high-side configurations. Its RDS(on) remains stable across temperature (25 °C to 150 °C) due to SIPMOS® process optimization, and it supports fast switching with tr = 25–33 ns and tf = 87–130 ns at VDD = -25 V.
The integrated body diode exhibits trr = 80–120 ns and Qrr = 125–190 nC, enabling reliable operation in flyback and synchronous rectification topologies. Avalanche energy rating EAS = 1.8 mJ (ID = -1.9 A, RGS = 25 Ω) confirms ruggedness against inductive load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR(DSS) | -60 V - Maximum blocking voltage before avalanche conduction begins |
| RDS(on) max | 0.21 Ω at VGS = -10 V, ID = -1.9 A - Enables <1.5 W conduction loss at rated current |
| VGS(th) | -1.5 V typ - Ensures full enhancement with standard 3.3 V or 5 V logic-level drive |
| ID cont | -1.9 A at TA = 70 °C - Supports compact thermal design on minimal PCB copper area |
| EAS | 1.8 mJ - Withstands single-pulse inductive energy without failure |
| dv/dt rating | 1 kV/µs - Resists false triggering in noisy high-dv/dt environments |
| Qg | 13–20 nC - Determines gate driver current requirement for 100 kHz+ switching |
Pinout & Package
Package: PG-SOT223 (standard SOT-223 outline with exposed drain pad for thermal performance; JEDEC MO-178 variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Drain) | Main current path collector | Connected to large copper pour for heat dissipation; electrically tied to tab |
| Pin 2 (Gate) | Control terminal | High-impedance input requiring <100 nA leakage; sensitive to ESD (Class 1a) |
| Pin 3 (Source) | Reference node for gate drive | Common return for load current; defines VGS reference point |
| Tab (Drain) | Thermal and electrical extension of Drain | Must be soldered to PCB copper for RthJA = 70 K/W (6 cm² cooling) |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) ≤ -2 V enables direct interface with 3.3 V microcontrollers without level-shifting |
| Avalanche-rated | Guaranteed single-pulse EAS = 1.8 mJ supports unclamped inductive switching in relay drivers |
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements |
| Halogen-free & RoHS | Complies with IEC61249-2-21 and EU RoHS Directive (Pb-free plating) |
Applications
| Automotive Door Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Driving window lift motors and mirror actuators in 12 V battery-powered door control units. IC Role / Device Role / Timing Role: High-side load switch controlling bidirectional motor current via H-bridge half-bridge configuration. Use Value: -60 V rating accommodates load dump transients up to ISO 7637-2 Pulse 5a; RDS(on) < 0.25 Ω limits self-heating during 1.5 A stall current. | Use Scenario: Isolating analog sensor outputs (e.g., pressure, temperature) from shared supply rails in PLC I/O modules. IC Role / Device Role / Timing Role: Low-leakage power switch enabling rail-to-rail signal integrity during sensor sleep/wake cycles. Use Value: IDSS ≤ -0.1 µA at 25 °C ensures <10 nA channel leakage, preserving sub-µA sensor bias accuracy. |
| LED Lighting Driver | USB-C Power Delivery Load Switch |
Use Scenario: PWM dimming control of 24 V architectural LED strings in smart building systems. IC Role / Device Role / Timing Role: Low-side current sink switch operating at 1–10 kHz with fast tf < 130 ns. Use Value: Qg = 13–20 nC allows clean edge transitions using 10 mA gate drivers; body diode trr < 120 ns prevents cross-conduction in synchronous buck stages. | Use Scenario: Enabling/disabling VBUS (5–20 V) to downstream USB-C peripherals during hot-plug events. IC Role / Device Role / Timing Role: Controlled power sequencer with soft-start behavior enabled by gate capacitance and external RC. Use Value: dv/dt rating of 1 kV/µs suppresses false turn-on during rapid VBUS ramp-up; RDS(on) stability over temperature ensures consistent current limiting across -40 to +125 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UVT-7 | RDS(on) = 0.045 Ω @ VGS = -4.5 V; SOT-23 package; lower ID rating (-4.2 A) | Higher current density but limited thermal mass; unsuitable for >1 W continuous dissipation | Select when board space is critical and peak ID < 2 A with aggressive heatsinking |
| IRLML6344TRPBF | RDS(on) = 0.055 Ω @ VGS = -4.5 V; SOT-23; no AEC-Q101 qualification | Lacks automotive stress validation; higher gate charge (22 nC) increases driver demand | Prefer for cost-sensitive industrial consumer designs where AEC-Q101 is not mandated |
Compared with DMG2305UVT-7 and IRLML6344TRPBF, BSP171PE6327T trades slightly higher RDS(on) for superior thermal robustness (SOT223 vs SOT-23), guaranteed avalanche capability, and automotive-grade reliability-making it optimal for thermally constrained yet mission-critical 12–24 V load switching.

FAQ
Is BSP171PE6327T suitable for high-side switching in 24 V automotive systems?
Yes. Its -60 V VBR(DSS), AEC-Q101 qualification, and 1 kV/µs dv/dt rating make it suitable for high-side 24 V loads subject to load dump transients per ISO 7637-2. The -1.5 V VGS(th) ensures reliable turn-on with 3.3 V or 5 V controllers when used with appropriate gate pull-up networks.
What is the maximum continuous drain current at 100 °C ambient?
At TA = 100 °C, continuous drain current is derated to approximately -1.1 A based on the thermal resistance curve (RthJA = 70 K/W with 6 cm² copper). This assumes vertical PCB mounting in still air and proper soldering of the drain tab to maximize heat transfer.
Does BSP171PE6327T include an integrated ESD protection diode?
No. While rated Class 1a per JESD22-A114-HBM (±250 V), it lacks internal ESD clamps beyond inherent MOSFET junction behavior. External TVS or RC filtering is recommended for gate protection in high-noise environments such as automotive CAN domains or motor drive zones.
Can the body diode be used for reverse polarity protection?
Yes. The integrated body diode supports continuous forward current of -1.9 A and pulse current up to -7.6 A. For reverse polarity protection, connect source to input and drain to output; ensure VSD ≤ -1.1 V at full load to limit power dissipation, and verify trr does not cause shoot-through in adjacent FETs.
