Product details
Overview
BSS84DWQ from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT363 package, rated for -50V VDSS, 10Ω RDS(ON) at VGS = -5V, and -130mA continuous drain current. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive power management, analog switching, and general-purpose interfacing where low gate threshold (-0.8V to -2.0V) and fast switching (tD(ON) = 10ns) are critical.
For engineers reviewing the BSS84DWQ datasheet, BSS84DWQ pinout, BSS84DWQ application, or BSS84DWQ equivalent, this part supports high-reliability automotive signal routing and load switching with verified thermal performance (RθJA = 417°C/W), low input capacitance (Ciss = 45pF), and IATF 16949-certified manufacturing.
Technical Context
This dual P-channel MOSFET integrates two identical enhancement-mode transistors in a single SOT363 package, sharing no internal connection between channels. Each channel operates independently with gate threshold voltage centered at -1.6V and exhibits stable RDS(ON) across -55°C to +150°C junction temperature range.
Its low Ciss/Coss ratio (45pF/25pF) and 12pF Crss support clean turn-on/turn-off transitions under 50Ω gate drive. The device is characterized for operation up to -50V VDSS with guaranteed breakdown at -75V under pulsed conditions, and IDSS leakage limited to -100nA at VDS = -25V, TJ = +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -50V maximum drain-source blocking voltage - supports 24V automotive rail switching with 100% margin over nominal system voltage |
| RDS(ON) | 10Ω max at VGS = -5V, ID = -0.1A - enables <13mW conduction loss at full rated current |
| ID (continuous) | -130mA at TA = +25°C - suitable for low-power logic-level load control and signal gating |
| VGS(th) | -0.8V to -2.0V - ensures reliable turn-on with 3.3V or 5V microcontroller outputs without level-shifting |
| Ciss | 45pF typical - minimizes gate drive energy and reduces switching transition time in high-frequency PWM applications |
| tD(ON) | 10ns typical - supports >10MHz switching in discrete gate driver stages and analog multiplexing circuits |
| PD | 300mW at TA = +25°C - defines thermal derating curve usable up to +85°C ambient with standard FR-4 PCB layout |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, dual-channel discrete package with exposed drain pads for thermal dissipation; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source 1) | Source terminal of Channel 1 | Low-impedance return path for Channel 1; internally connected to Pin 4 (Source 2) only in common-source configuration variants - not connected here |
| 2 (Gate 1) | Control input for Channel 1 | Accepts negative gate bias relative to Source 1; threshold behavior validated down to -0.8V for logic-compatible drive |
| 3 (Drain 1) | Output terminal of Channel 1 | High-side or low-side switch node; rated for -50V blocking and -130mA continuous conduction |
| 4 (Source 2) | Source terminal of Channel 2 | Independent source node; electrically isolated from Source 1 per internal schematic and package marking diagram |
| 5 (Gate 2) | Control input for Channel 2 | Independent gate with identical VGS(th) and Ciss characteristics as Gate 1 |
| 6 (Drain 2) | Output terminal of Channel 2 | Second independent switching node; matched RDS(ON) and dynamic parameters to Channel 1 |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(th) down to -0.8V enables direct interface with 3.3V CMOS logic without pull-up resistors or level shifters |
| Matched dual-channel structure | Identical electrical specs across both channels support symmetrical analog switching and redundant power paths |
| Automotive qualification | AEC-Q101 qualification, PPAP documentation, and IATF 16949 manufacturing ensure supply continuity and failure-rate compliance for Tier-1 systems |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets global environmental mandates without compromising thermal or mechanical reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG1012TQ-7 | RDS(ON) = 8Ω @ VGS = -4.5V; higher Ciss (60pF); same SOT363 package | Better conduction efficiency at lower gate drive but slower switching in high-frequency PWM | Select when optimizing for <100mW static loss over switching speed in battery-powered sensors |
| FDMA1023PZ | Single-channel SOT-363; RDS(ON) = 9Ω @ VGS = -4.5V; no dual-channel integration | Requires two devices for dual-path operation; increases board area and assembly cost | Choose only if legacy design requires pin-for-pin replacement of single-channel variant with known layout constraints |
Compared with DMG1012TQ-7 and FDMA1023PZ, the BSS84DWQ offers balanced trade-offs: its -1.6V typical VGS(th) ensures robust turn-on with 3.3V logic, while its 45pF Ciss and 10ns tD(ON) support faster switching than DMG1012TQ-7, and its integrated dual topology eliminates layout duplication required by FDMA1023PZ.

FAQ
Is BSS84DWQ-13 RoHS and REACH compliant?
Yes. BSS84DWQ-13 is fully RoHS 3 (2015/863/EU) compliant with no intentionally added lead, and meets REACH SVHC requirements. Its "Green" designation confirms bromine and chlorine content below 900ppm each, and antimony below 1000ppm, verified per Diodes' material declarations and third-party test reports.
What is the maximum operating temperature for continuous use?
The BSS84DWQ supports continuous operation from -55°C to +150°C junction temperature. At ambient temperatures above +85°C, derating applies: maximum power dissipation drops linearly from 300mW at +25°C to 0mW at +150°C, based on RθJA = 417°C/W and standard FR-4 PCB layout.
Can BSS84DWQ be used in linear (analog) mode?
Yes. The device's specified gFS = 0.05S and monotonic RDS(ON) vs. VGS curve (Fig. 4) confirm stable transconductance behavior. It is routinely applied in analog multiplexers and programmable gain stages where VDS remains ≤ ±5V and power dissipation stays within 100mW limits.
Does the SOT363 package include thermal pad exposure?
No. The SOT363 package used for BSS84DWQ has no exposed thermal pad. Thermal performance relies on copper pour under pins 3 and 6 (Drain 1 and Drain 2), with recommended pad layout dimensions (C = 0.65mm, G = 1.30mm) published in Diodes' package outline document DS00001.
