Product details
Overview
BSS84PH6433XTMA1 from Infineon Technologies is a P-channel enhancement-mode logic-level SIPMOS™ small-signal MOSFET in PG-SOT-23 package, rated for −60 V VDS, 8 Ω RDS(on) at VGS = −4.5 V, and −0.17 A continuous drain current. It features avalanche rating, dv/dt robustness (−6 kV/µs), and AEC-Q101 qualification for automotive signal switching.
For engineers reviewing the BSS84PH6433XTMA1 datasheet, BSS84PH6433XTMA1 pinout, BSS84PH6433XTMA1 application, or BSS84PH6433XTMA1 equivalent, key selection criteria include logic-level gate drive compatibility, low RDS(on) at −4.5 V, SOT-23 thermal performance, and automotive-grade reliability under transient stress conditions.
Technical Context
This device operates as a single P-channel MOSFET with enhancement-mode threshold behavior (VGS(th) = −1.0 to −2.0 V) and integrated body diode. Its avalanche-rated construction supports unclamped inductive switching, while dv/dt rating ensures immunity to parasitic turn-on in high-noise environments.
The PG-SOT-23 package uses pin 1 for gate, pin 2 for source, and pin 3 for drain-enabling compact layout in space-constrained PCBs. Thermal resistance RthJA is 300 K/W on 6 cm² copper, supporting stable operation up to 150 °C junction temperature.

| EAS | 2.6 mJ - supports reliable energy absorption during inductive load turn-off transients |
| dv/dt rating | −6 kV/µs - prevents false triggering in noisy motor control or relay driver circuits |
| VGS(th) | −1.0 to −2.0 V - ensures turn-on with standard 3.3 V or 5 V logic outputs |

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 |
|---|---|---|---|
| DMG2305UX-13 | RDS(on) = 45 mΩ @ −4.5 V; higher current rating (−4.2 A); larger SOT-23 footprint | Designed for higher-power load switching; not optimized for ultra-low leakage or automotive qualification | Select when higher current handling is required and AEC-Q101 is not mandatory |
| SI2301DS-T1-BE3 | RDS(on) = 115 mΩ @ −4.5 V; lower VDS (−20 V); no avalanche rating | Targeted at consumer portable devices; lacks dv/dt immunity and automotive stress testing | Select for cost-sensitive non-automotive applications where voltage and energy stress are minimal |
Compared with DMG2305UX-13 and SI2301DS-T1-BE3, BSS84PH6433XTMA1 uniquely balances logic-level drive, −60 V rating, avalanche ruggedness, and AEC-Q101 compliance-making it optimal for safety-critical, low-current automotive signal switching where reliability under transient stress is essential.

FAQ
Is BSS84PH6433XTMA1 suitable for high-side switching configurations?
Yes. With its P-channel architecture, source terminal referenced to the positive rail, and logic-level gate threshold (−1.0 to −2.0 V), it functions reliably as a high-side switch. The −60 V VDS rating supports use in 24 V automotive systems, and the PG-SOT-23 pinout (pin 2 = source) simplifies PCB layout for this topology.
What is the maximum operating temperature and thermal derating behavior?
The device supports junction temperatures from −55 °C to +150 °C. Power dissipation derates linearly above 25 °C ambient: Ptot drops from 0.36 W at 25 °C to zero at ~125 °C on a 6 cm² copper pad. RthJA is 300 K/W under those conditions, enabling accurate thermal design in sealed enclosures.
Does BSS84PH6433XTMA1 require external gate resistors for ESD or switching control?
No external gate resistor is required for basic logic-level switching, but a 10–100 Ω series resistor is recommended to dampen ringing and limit peak gate current during fast transitions. The device's ESD Class 0 rating (per JESD22-A114-HBM) mandates careful handling, though internal protection suffices for typical PCB-level ESD events.
How does the avalanche rating impact real-world circuit design?
The 2.6 mJ single-pulse avalanche energy rating allows the MOSFET to safely absorb inductive energy from loads like solenoids or relays during turn-off without external snubbers. This simplifies board design and improves system reliability in automotive and industrial applications where inductive transients are frequent and unpredictable.
