Product details
Overview
BSP321PL6327HTSA1 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 high-side load switch or reverse-polarity protection device in automotive body electronics and industrial power management.
For engineers reviewing the BSP321PL6327HTSA1 datasheet, BSP321PL6327HTSA1 pinout, BSP321PL6327HTSA1 application, or BSP321PL6327HTSA1 equivalent, key selection criteria include its -100 V breakdown voltage, -2.1 to -4.0 V gate threshold range, 240–319 pF input capacitance, integrated avalanche energy rating (57 mJ), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates in enhancement mode with normal-level gate drive compatibility (VGS(th) = -2.1 to -4.0 V), enabling direct interface with standard 3.3 V or 5 V logic controllers without level shifting. Its avalanche rating supports unclamped inductive switching in relay drivers and solenoid controls.
The PG-SOT-223 package provides thermal resistance of 70 K/W (with 6 cm² copper area) and supports continuous drain current up to -0.79 A at TC = 70 °C. The integrated body diode exhibits 0.84–1.2 V forward voltage at -0.98 A and 47 ns reverse recovery time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -100 V - Withstands up to -100 V drain-source blocking voltage, suitable for 24 V and 48 V automotive systems with load dump transients. |
| RDS(on) | 689–900 mΩ @ VGS = -10 V, ID = -0.98 A - Defines on-state conduction loss and junction temperature rise under nominal load conditions. |
| VGS(th) | -2.1 to -4.0 V - Ensures reliable turn-on with standard logic-level gate drives while avoiding spurious activation near 0 V. |
| EAS | 57 mJ - Specifies single-pulse avalanche energy capability, critical for inductive load switching without external snubbers. |
| Ciss | 240–319 pF - Determines gate drive strength requirement and switching speed limitation in high-frequency PWM applications. |
| ID | -0.98 A continuous @ TC = 25 °C - Maximum steady-state current before thermal derating begins; usable up to -0.79 A at 70 °C case temperature. |
| VSD | 0.84–1.2 V @ IF = -0.98 A - Forward voltage drop of integrated body diode, directly impacting freewheeling efficiency in H-bridge or flyback topologies. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UX-13 | VDS = -20 V, RDS(on) = 45 mΩ @ -4.5 V - lower voltage rating, much lower on-resistance | Suitable only for ≤12 V systems; not rated for automotive load dump or AEC-Q101 | Select when low-voltage, high-current switching is needed and automotive qualification is unnecessary. |
| IPD250N10N3G | VDS = -100 V, RDS(on) = 250 mΩ @ -10 V - higher current (25 A), TO-252 package, no AEC-Q101 | Designed for high-power motor drives; lacks automotive qualification and SOT-223 form factor | Choose for higher current capacity where board space allows TO-252 and automotive compliance is not required. |
Compared with DMG2305UX-13 and IPD250N10N3G, BSP321PL6327HTSA1 uniquely balances -100 V rating, AEC-Q101 qualification, SOT-223 footprint, and 1 A-class current handling-making it optimal for space- and reliability-constrained automotive and industrial high-side switching.

FAQ
Is BSP321PL6327HTSA1 suitable for high-side switching in 24 V automotive systems?
Yes. With -100 V VDS, AEC-Q101 qualification, and 57 mJ avalanche energy rating, it withstands ISO 7637-2 load dump transients and operates reliably as a high-side switch in 24 V systems such as lighting and ECU power distribution. Thermal derating must be applied above 70 °C case temperature.
What is the recommended gate resistor value for driving BSP321PL6327HTSA1 in PWM applications?
A 10 Ω to 47 Ω series gate resistor is recommended to balance switching speed and EMI. With 9–12 nC total gate charge and 4–6 nC Qgd, this range limits dV/dt to ~10–20 V/ns while preventing ringing. Lower values may cause overshoot; higher values increase switching losses beyond 100 kHz operation.
Does BSP321PL6327HTSA1 include an integrated ESD protection diode?
No. It is rated JESD22-A114-HBM Class 1A (250–500 V), meaning basic ESD tolerance is built-in but no dedicated on-chip protection diode is present. External TVS or RC filtering is advised for gate inputs in noisy automotive environments per ISO 10605 requirements.
Can the body diode of BSP321PL6327HTSA1 be used for freewheeling in inductive loads?
Yes. The integrated body diode supports continuous forward current up to -0.98 A and pulse current up to -3.9 A, with 0.84–1.2 V VSD and 47 ns trr. It is suitable for freewheeling in low-frequency (<10 kHz) inductive loads like relays and solenoids, though external Schottky diodes are preferred for high-frequency or high-efficiency designs.
