Product details
Overview
BSP171PE6327 from Infineon Technologies is a P-channel enhancement-mode SIPMOS® small-signal MOSFET rated for -60 V drain-source breakdown, 0.21 Ω RDS(on) at VGS = -10 V and ID = -1.9 A, and avalanche-rated operation; used in automotive load switching and industrial power management circuits requiring logic-level gate drive and robust transient immunity.
For engineers reviewing the BSP171PE6327 datasheet, BSP171PE6327 pinout, BSP171PE6327 application, or BSP171PE6327 equivalent, key selection criteria include its -1.5 V gate threshold voltage, 25 K/W junction-to-soldering-point thermal resistance, -1.9 A continuous drain current capability, and SOT-223 package suitability for high-reliability PCB layouts with minimal copper area.
Technical Context
This device operates as a logic-level P-channel MOSFET with avalanche energy rating of 1.8 mJ (ID = -1.9 A, RGS = 25 Ω), enabling robust operation under inductive switching transients. Its dv/dt rating of 1 kV/µs supports reliable commutation in noisy environments without spurious turn-on.
Designed for surface-mount implementation on FR4 PCBs with 6 cm² copper cooling area, it delivers 0.21 Ω RDS(on) at -10 V gate drive and maintains stable threshold voltage (-1.0 to -2.0 V) across -55 °C to +150 °C operating range per AEC-Q101 qualification.
Key Specifications

| ID cont | -1.9 A at TA = 25 °C - Continuous current handling with standard PCB cooling |
| EAS | 1.8 mJ - Single-pulse avalanche energy tolerance ensures reliability during inductive load turn-off |
| RthJS | 25 K/W - Thermal resistance from junction to soldering point enables predictable thermal design |
| Ciss | 460 pF max - Input capacitance impacts gate drive power and switching speed |
| tr/tf | 25 ns / 87 ns - Fast switching transitions reduce switching losses in PWM applications |
Pinout & Package
Package: PG-SOT223 (standard SOT-223 outline with exposed drain pad); thermally optimized for vertical mounting on FR4 PCB with 6 cm² copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Drain) | Main current-carrying terminal | Connected to large copper area for heat dissipation and low-inductance power path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UX-13 | RDS(on) = 0.045 Ω @ -4.5 V (lower), but VBR(DSS) = -20 V (reduced voltage rating) | Suitable only for ≤20 V systems; not viable for 24 V automotive loads | Select only when lower gate drive voltage and higher current density outweigh voltage margin needs |
| IRLML6344TRPBF | RDS(on) = 0.055 Ω @ -4.5 V, VBR(DSS) = -20 V, no AEC-Q101 qualification | Lacks automotive qualification and avalanche rating; limited to commercial-grade applications | Prefer for cost-sensitive consumer electronics where qualification and ruggedness are secondary |
Compared with DMG2305UX-13 and IRLML6344TRPBF, BSP171PE6327 uniquely combines -60 V rating, AEC-Q101 qualification, and 1.8 mJ avalanche energy-making it the only option for safety-critical 24 V automotive switching where overvoltage transients exceed 40 V.

FAQ
What is the maximum safe operating temperature for BSP171PE6327?
The junction temperature must not exceed +150 °C under steady-state or transient conditions. The device is rated for storage and operation from -55 °C to +150 °C, with thermal resistance RthJA = 70 K/W on a 6 cm² copper PCB. Derating is required above 70 °C ambient per the Ptot vs. TA curve on page 4 of the datasheet.
Does BSP171PE6327 require a gate resistor for driving with a microcontroller?
A gate resistor of 10–100 Ω is recommended to dampen ringing and limit peak gate current during fast switching. While the gate threshold is logic-compatible, uncontrolled gate drive can cause oscillation due to Ciss = 460 pF and layout parasitics; the resistor also protects MCU GPIO pins from capacitive inrush.
Can BSP171PE6327 be used in linear (analog) regulation mode?
No-it is not characterized or guaranteed for linear-mode operation. The Safe Operating Area (SOA) graph on page 4 shows only pulsed and DC limits at specific VDS–ID points; sustained linear operation risks thermal runaway due to positive temperature coefficient of RDS(on) and lack of SOA derating data.
Is the SOT-223 package lead-free and RoHS compliant?
Yes-BSP171PE6327 uses Pb-free lead plating and meets RoHS Directive 2011/65/EU requirements. It is also halogen-free per IEC61249-2-21 and qualified to JESD22-A114-HBM Class 1a ESD standards.
