Product details
Overview
BSP321PL6327 from Infineon Technologies is a P-channel enhancement-mode SIPMOS® small-signal MOSFET rated for -100 V VDS, 900 mΩ RDS(on) at -10 V VGS and -0.98 A ID, avalanche-rated, AEC-Q101 qualified, and housed in PG-SOT-223 package. It serves as a robust low-side load switch in automotive body electronics and industrial power control circuits requiring high reliability under repetitive surge conditions.
For engineers reviewing the BSP321PL6327 datasheet, BSP321PL6327 pinout, BSP321PL6327 application, or BSP321PL6327 equivalent, key selection criteria include its -100 V breakdown rating, 900 mΩ on-resistance at -10 V gate drive, -0.98 A continuous drain current, avalanche energy rating (EAS = 57 mJ), and AEC-Q101 qualification for automotive-grade deployment.
Technical Context
This device operates in enhancement mode with a gate threshold voltage range of -2.1 V to -4.0 V, enabling direct interface with standard 3.3 V/5 V logic when used with appropriate level-shifting or pull-up configuration. Its integrated body diode supports freewheeling in inductive loads, with VSD = 0.84–1.2 V at IF = 0.98 A and trr = 47 ns.
The MOSFET exhibits Ciss = 240–319 pF, Coss = 62–82 pF, and Qg = 9–12 nC, supporting fast switching in DC-DC converters and LED drivers. Thermal resistance RthJA is 115 K/W (min footprint) or 70 K/W (6 cm² copper), confirming suitability for thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -100 V - Withstands reverse-biased drain-source transients up to 100 V without breakdown. |
| RDS(on) max | 900 mΩ at VGS = -10 V, ID = -0.98 A - Ensures <1 V conduction loss at rated current, minimizing heat generation. |
| ID cont | -0.98 A at TC = 25 °C - Supports stable operation in low-power switching nodes such as sensor biasing or solenoid control. |
| EAS | 57 mJ - Absorbs single-pulse inductive energy without failure, critical for relay or motor coil snubbing. |
| VGS(th) | -2.1 to -4.0 V - Enables reliable turn-on with 5 V microcontroller GPIO or dedicated gate drivers. |
| Qg | 9–12 nC - Determines gate drive power requirement and switching speed in PWM applications. |

Pinout & Package
Package: PG-SOT-223 - Surface-mount plastic package with exposed drain pad for thermal dissipation; compatible with standard SMT reflow profiles and IPC-7351B land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Reference node for gate drive; connects to system ground or low-side return path. |
| Pin 2 (Gate) | Control input | Receives negative gate voltage relative to source to enable conduction; requires ESD protection. |
| Pin 3 (Drain) | Power output | High-side connection point for load; electrically tied to exposed metal tab for thermal conduction. |
| Tab (Drain) | Thermal & electrical drain | Provides primary thermal path to PCB copper; must be soldered to ≥6 cm² copper area for rated power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated operation | Guarantees single-pulse ruggedness up to 57 mJ, eliminating need for external clamping in inductive switching. |

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 |
|---|---|---|---|
| DMG2305UVT-7 | RDS(on) = 48 mΩ @ -4.5 V (lower), VDS = -20 V (lower), SOT-23 package (smaller, lower thermal mass) | Not suitable for >20 V systems; limited to portable electronics and low-voltage logic-level switching. | Select only if operating voltage ≤20 V and board space is constrained. |
| IPD250N10N3G | RDS(on) = 2.5 mΩ @ -10 V (much lower), TO-252 package (higher thermal capacity), VDS = -100 V (same) | Designed for high-current (>20 A) motor drives; overqualified for sub-1 A signal switching. | Choose only when thermal budget exceeds 1 W and PCB layout allows DPAK footprint. |
Compared with DMG2305UVT-7 and IPD250N10N3G, BSP321PL6327 uniquely balances -100 V capability, AEC-Q101 qualification, and SOT-223 thermal performance for cost-sensitive automotive and industrial 12–24 V load switching where both ruggedness and moderate current handling are required.

FAQ
Is BSP321PL6327 suitable for 24 V industrial control applications?
Yes. With a -100 V VDS rating and AEC-Q101 qualification, it supports 24 V nominal systems including surge margins up to ±80 V. Its RDS(on) remains stable across -40 °C to +125 °C junction temperature, ensuring predictable performance in PLC I/O modules and factory automation controllers.
What is the maximum safe gate-source voltage for BSP321PL6327?
The absolute maximum VGS is ±20 V per datasheet. Operation beyond ±15 V risks oxide degradation. For reliable long-term use, gate drive should be limited to -10 V for full enhancement and +5 V for guaranteed off-state, with series gate resistor (≥10 Ω) to limit dv/dt-induced ringing.
Does BSP321PL6327 require a heatsink in typical operation?
No external heatsink is required below 0.5 W power dissipation. At ID = -0.98 A and RDS(on) = 900 mΩ, conduction loss is ~0.96 W - manageable with ≥6 cm² PCB copper area per Infineon's thermal guidelines. Forced airflow or larger copper pours reduce junction temperature further.
Can BSP321PL6327 replace N-channel MOSFETs in high-side configurations?
No. As a P-channel device, it is inherently suited for low-side switching. High-side use requires gate voltage more positive than source - incompatible with its -100 V VDS rating and threshold behavior. For high-side 12 V/24 V switching, a dedicated high-side driver with N-channel MOSFET or integrated high-side switch is required.
