Product details

Overview

BSS84PL6433HTMA1 from Infineon Technologies is a P-channel enhancement-mode logic-level SIPMOS™ small-signal MOSFET in PG-SOT-23 package, rated for −60 V V_DS, 8 Ω R_DS(on) at V_GS = −4.5 V, and −0.17 A continuous drain current; used in low-power load switching, level translation, and reverse polarity protection circuits.

For engineers reviewing the BSS84PL6433HTMA1 datasheet, BSS84PL6433HTMA1 pinout, BSS84PL6433HTMA1 application, or BSS84PL6433HTMA1 equivalent, key selection criteria include avalanche rating (2.6 mJ), dv/dt immunity (−6 kV/µs), AEC-Q101 qualification, halogen-free compliance, and logic-level gate drive compatibility with 3.3 V/5 V controllers.

Technical Context

This device operates as a single P-channel MOSFET with enhancement-mode threshold behavior (V_GS(th) = −1.0 to −2.0 V) and integrated body diode (V_SD = −0.93 to −1.24 V). It supports fast switching with t_r = 16.2–24.3 ns and t_f = 20.5–30.8 ns under specified conditions.

Thermal design is enabled by R_thJA = 300–350 K/W on FR4 PCB with 6 cm² copper area, and it sustains operation across −55 °C to +150 °C junction temperature with T_jmax-limited periodic avalanche energy (E_AR = 0.036 mJ).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	−60 V - supports rail-to-rail negative supply switching up to industrial −48 V systems
R_DS(on) @ V_GS = −4.5 V	8 Ω max - enables low-loss switching at 3.3 V logic-level gate drive
I_D Continuous	−0.17 A @ 25 °C - suitable for signal-level and auxiliary power path control
Avalanche Energy E_AS	2.6 mJ single-pulse - provides robustness against inductive turn-off transients
dv/dt Immunity	−6 kV/µs - prevents false turn-on in noisy high-speed switching environments
Q_g Total	1.0–1.5 nC - ensures efficient gate driving with minimal controller loading
V_GS(th)	−1.0 to −2.0 V - guarantees reliable turn-on with standard logic outputs

Pinout & Package

Package: PG-SOT-23 (JEDEC TO-236AB), surface-mount, 3-pin plastic case with exposed drain pad for thermal conduction.

Pin 2	Source	Reference node for gate drive; connected to higher potential in high-side switch configurations
Pin 3	Drain	Power output terminal; thermally coupled to PCB copper for heat dissipation (R_thJS = 200 K/W)

Key Features

Feature	Design Value
AEC-Q101 Qualified	Validated for automotive-grade reliability per stress test requirements (HTRB, H3TRB, TC, etc.)
Halogen-Free	Complies with IEC61249-2-21; eliminates brominated flame retardants in PCB assembly
Logic-Level Gate	V_GS(th) ≤ −2.0 V ensures full enhancement with 3.3 V GPIO without level-shifting
Integrated Body Diode	V_SD ≤ −1.24 V at −0.17 A enables bidirectional current handling in flyback/clamp paths
Avalanche Rated	Rated for repetitive and single-pulse avalanche operation up to E_AS = 2.6 mJ

Applications

Reverse Polarity Protection

Low-Voltage Level Shifter

Use Scenario: Protecting 3.3 V or 5 V USB-powered peripherals from accidental reverse battery connection.

IC Role / Device Role / Timing Role: High-side P-channel switch placed between input supply and system VCC rail.

Use Value: Prevents damage during miswiring while maintaining < 1.4 V dropout at full load due to low R_DS(on).

Use Scenario: Translating 1.8 V GPIO signals to interface with 5 V legacy peripherals.

IC Role / Device Role / Timing Role: Bidirectional level translator using common-source configuration with pull-up resistors.

Use Value: Achieves sub-10 ns propagation delay and rail-to-rail voltage translation without active logic.

Load Switch for IoT Sensors

ESD-Protected Signal Clamp

Use Scenario: Power gating low-current sensors (e.g., temperature, humidity) in battery-operated edge nodes.

IC Role / Device Role / Timing Role: Controlled power switch enabling deep-sleep current reduction below 1 µA.

Use Value: Delivers < 0.1 µA off-state leakage (I_DSS) and supports rapid wake-up via MCU GPIO.

Use Scenario: Clamping analog sensor inputs (e.g., ADC reference pins) against ESD and overvoltage events.

IC Role / Device Role / Timing Role: Fast-recovery body diode used in back-to-back configuration with series resistor.

Use Value: Limits transient voltage to < −1.24 V with t_rr = 23–34 ns, minimizing signal distortion.

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
DMN2053LFG-7	R_DS(on) = 4.5 Ω @ −4.5 V; higher I_D = −2.8 A; SOT-23 package	Higher current capability but larger gate charge (Q_g = 3.2 nC); less suitable for ultra-low-power sleep modes	Select when higher continuous current and lower on-resistance outweigh gate drive efficiency needs.
SI2301DS-T1-BE3	R_DS(on) = 11 Ω @ −4.5 V; V_GS(th) = −0.7 to −1.3 V; not AEC-Q101 qualified	Lacks automotive qualification and avalanche rating; lower cost for consumer-grade applications only	Choose for cost-sensitive non-automotive designs where transient robustness is secondary.

Compared with DMN2053LFG-7 and SI2301DS-T1-BE3, BSS84PL6433HTMA1 offers superior dv/dt immunity (−6 kV/µs), guaranteed avalanche performance (2.6 mJ), and AEC-Q101 validation-making it optimal for safety-critical, noise-prone, or automotive-adjacent embedded systems requiring predictable failure modes.

FAQ

Is BSS84PL6433HTMA1 suitable for high-frequency PWM switching?

Yes-it supports PWM frequencies up to ~10 MHz in low-duty-cycle applications due to t_r/t_f of 16–31 ns and Q_g < 1.5 nC. However, thermal limits (P_tot = 0.36 W) constrain sustained high-frequency operation above 100 kHz without heatsinking or derating.

What is the maximum safe operating voltage for avalanche testing?

The device is characterized for single-pulse avalanche at V_DD = −25 V, I_D = −0.17 A, and R_GS = 25 Ω, yielding E_AS = 2.6 mJ. Operation beyond −25 V in avalanche mode is not validated and may exceed SOA limits.

Does the marking 'YBs' indicate RoHS or halogen-free status?

Yes-the 'YBs' top-side marking denotes halogen-free compliance per IEC61249-2-21 and RoHS Directive 2011/65/EU, confirmed in the official Infineon datasheet revision 2.6.

Can BSS84PL6433HTMA1 replace BSS84 in existing designs?

Yes-BSS84PL6433HTMA1 is a direct replacement for legacy BSS84 with identical pinout, electrical specs, and enhanced features including AEC-Q101 qualification and halogen-free construction; no layout or firmware changes required.
