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) @ VGS = -5V, and -130mA continuous drain current. It serves as a compact, AEC-Q101-qualified load switch or analog switch in automotive power management and signal routing circuits.
For engineers reviewing the BSS84DWQ datasheet, BSS84DWQ pinout, BSS84DWQ application, or BSS84DWQ equivalent, key selection criteria include gate threshold voltage (-0.8 to -2.0V), low input capacitance (45pF Ciss), fast switching (10ns tD(ON)), thermal resistance (417°C/W), and IATF 16949 manufacturing compliance.
Technical Context
This dual MOSFET integrates two identical P-channel devices in a single SOT363 package with independent drain, source, and gate terminals per channel. Its low gate threshold enables direct interfacing with 3.3V/5V logic without level shifting.
The device operates within -55°C to +150°C junction temperature range and delivers stable RDS(ON) performance across temperature due to its silicon process optimization-RDS(ON) increases only ~1.5× from 25°C to 125°C at VGS = -10V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -50V - supports automotive 24V systems with margin against transients |
| RDS(ON) | 10Ω @ VGS = -5V - enables <1.3mW conduction loss at 130mA |
| ID (max) | -130mA - suitable for low-power load switching and bias control |
| Ciss | 45pF - minimizes gate drive energy and improves switching efficiency |
| tD(ON) | 10ns - supports >10MHz digital switching in signal path applications |
| PD | 300mW - requires minimal PCB copper area for thermal relief on FR-4 |
| VGS(th) | -0.8 to -2.0V - ensures reliable turn-on with standard CMOS logic outputs |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, dual-channel discrete package with 0.65mm lead pitch; moisture sensitivity level 1 per J-STD-020; matte tin-plated alloy 42 leadframe.

| 2 | Drain of Channel 1 | High-side or low-side switched output node |
| 3 | Source of Channel 1 | Return path for Channel 1; internally isolated from Source 2 |
| 4 | Source of Channel 2 | Independent return path for Channel 2 |
| 5 | Drain of Channel 2 | Second independent switched output node |
| 6 | Gate of Channel 2 | Separate logic-level control input for Channel 2 |
Key Features
| Feature | Design Value |
|---|---|

| Low VGS(th) | -0.8V minimum - ensures full enhancement with 1.8V/3.3V microcontroller GPIO |
| Low Ciss | 45pF - limits gate charge to ~0.45nC, easing drive requirements |
| AEC-Q101 qualified | Validated for automotive use per stress test requirements - supports PPAP documentation |
| Green construction | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) - meets global environmental mandates |

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 | RDS(ON) = 4.5Ω @ VGS = -4.5V; higher ID (−200mA); same SOT363 package | Better conduction efficiency in 3.3V logic-driven loads; slightly higher leakage at 125°C | Select when lower on-resistance is critical and gate drive is ≥−4.5V |
| FDMA1023PZ | RDS(ON) = 8.5Ω @ VGS = -4.5V; AEC-Q101 qualified; different pinout (pin 1 = Source1, pin 2 = Drain1, pin 3 = Gate1) | Requires PCB layout revision; tighter VGS(th) distribution (−1.0 to −2.2V) | Choose for enhanced gate threshold consistency where precise turn-on voltage matters |
Compared with DMG1012TQ and FDMA1023PZ, the BSS84DWQ offers the widest VGS(th) range (−0.8 to −2.0V), lowest Ciss (45pF), and best thermal resistance (417°C/W), making it optimal for low-power, high-speed, and thermally constrained automotive signal-switching roles.

FAQ
Is BSS84DWQ suitable for hot-swap applications?
Yes. With -50V VDSS, low RDS(ON), and fast 10ns turn-on delay, the BSS84DWQ supports controlled inrush limiting in 12V/24V hot-swap circuits. Its 300mW power dissipation and 417°C/W thermal resistance require minimal copper area for transient current handling up to 130mA.
What is the maximum operating temperature for continuous use?
The BSS84DWQ is rated for continuous operation from -55°C to +150°C junction temperature. At ambient temperatures up to +85°C with standard FR-4 PCB layout, it sustains full -130mA current without derating, provided the 300mW power limit and thermal resistance are respected.
Does BSS84DWQ have integrated ESD protection?
No. The BSS84DWQ does not include on-die ESD protection diodes. External TVS devices are recommended for applications exposed to IEC 61000-4-2 level 4 (±8kV contact) environments, especially on gate inputs where ±20V VGS absolute maximum must not be exceeded.
Can both channels be paralleled for higher current capacity?
No. Paralleling channels is not recommended due to mismatched RDS(ON) and thermal coupling effects. Each channel is electrically isolated but shares a common package thermal path; simultaneous conduction increases junction temperature nonlinearly and risks thermal runaway under unbalanced loading.
