Product details
Overview
BSS84DW-7-F 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, designed for low-power analog and power-management switching in space-constrained PCBs.
For engineers reviewing the BSS84DW-7-F datasheet, BSS84DW-7-F pinout, BSS84DW-7-F application, or BSS84DW-7-F equivalent, key selection criteria include gate threshold voltage (-0.8 to -2.0V), input capacitance (45pF), thermal resistance (417°C/W), and JEDEC-qualified reliability for industrial and automotive-adjacent designs.
Technical Context
This dual discrete MOSFET integrates two identical P-channel silicon devices in a single 6-pin SOT363 package with independent drain-source-gate terminals per channel. Each channel operates with enhancement-mode logic, requiring negative gate bias relative to source to conduct.
It supports bidirectional blocking up to -50V, delivers fast switching (tD(ON) = 10ns, tD(OFF) = 18ns), and maintains stable RDS(ON) across -55°C to +150°C junction temperature range-enabling use in thermally variable environments without derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -50V - Maximum reverse drain-source voltage before avalanche breakdown; defines safe operating window in high-side switch configurations. |
| RDS(ON) | 10Ω @ VGS = -5V - On-resistance at standard gate drive; determines conduction loss in low-current (<130mA) load switching. |
| ID (max) | -130mA - Continuous DC drain current per channel at +25°C ambient; sets upper bound for steady-state load handling. |
| PD | 300mW - Total package power dissipation on FR-4 PCB; constrains thermal design for dual-channel operation. |
| Ciss | 45pF - Input capacitance at VDS = -25V; impacts gate drive strength requirements and switching speed in digital control interfaces. |
| VGS(th) | -0.8 to -2.0V - Gate threshold range; enables reliable turn-on with low-voltage logic (e.g., 3.3V or 5V microcontroller outputs). |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, dual-channel discrete MOSFET package with 0.65mm lead pitch, UL 94V-0 molded plastic body, and matte tin-plated Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Channel 1 Source) | Source terminal for first MOSFET | Reference node for VGS biasing; tied to local ground or higher potential depending on high/low-side configuration. |
| 2 (Channel 1 Gate) | Gate terminal for first MOSFET | Control input requiring negative voltage relative to its source to enable conduction; isolated from other channels. |
| 3 (Channel 1 Drain) | Drain terminal for first MOSFET | Load connection point; blocks up to -50V when off; conducts up to -130mA when fully enhanced. |
| 4 (Channel 2 Drain) | Drain terminal for second MOSFET | Independent load path; electrically isolated from Channel 1; supports dual independent switching functions. |
| 5 (Channel 2 Gate) | Gate terminal for second MOSFET | Separate control input; allows asynchronous or synchronized switching of second channel without crosstalk. |
| 6 (Channel 2 Source) | Source terminal for second MOSFET | Independent reference node; may be connected to same or different potential than Pin 1 based on circuit topology. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) | 6Ω typical @ VGS = -5V - Reduces I²R losses in battery-powered or energy-sensitive signal routing paths. |
| Low VGS(th) | -0.8V minimum - Ensures full enhancement with 3.3V logic-level gate drives, eliminating need for level shifters. |
| Low Ciss | 45pF - Minimizes gate charge demand and propagation delay in high-frequency switching (e.g., >1MHz PWM control). |
| JEDEC-qualified reliability | AEC-Q200-compliant stress testing - Validates suitability for extended-life industrial and automotive-adjacent applications. |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant - Meets environmental compliance mandates for global electronics manufacturing. |

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 |
|---|---|---|---|
| DMG6968U-7 | RDS(ON) = 2.2Ω @ VGS = -4.5V; higher ID (±3A); SO-8 package | Higher current capability but larger footprint; unsuitable for space-constrained SOT363 layouts | Select when >130mA load current or lower on-resistance is required; verify PCB pad compatibility. |
| FDMA1023PZ | RDS(ON) = 12Ω @ VGS = -4.5V; same SOT363 package; ±200mA ID rating | Nearly identical form factor and pinout; slightly higher RDS(ON) and current rating | Drop-in replacement if 12Ω on-resistance is acceptable; confirm gate threshold alignment with existing driver. |
Compared with DMG6968U-7 and FDMA1023PZ, the BSS84DW-7-F offers optimal balance of ultra-small footprint, low gate-threshold compatibility with 3.3V logic, and JEDEC-qualified reliability-making it preferred for compact, low-power, and long-lifecycle embedded systems where thermal and layout constraints dominate.

FAQ
Is BSS84DW-7-F suitable for automotive applications?
No-BSS84DW-7-F is not AEC-Q101 qualified. However, its automotive-grade variant BSS84DWQ is available under a separate datasheet and meets AEC-Q200 stress test requirements for passive components. For automotive designs, BSS84DWQ must be specified explicitly; BSS84DW-7-F is intended for industrial and commercial applications only.
What is the maximum allowable gate-source voltage?
The absolute maximum continuous gate-source voltage (VGS) is ±20V. Exceeding this rating risks permanent gate oxide damage. In practice, gate drive should be limited to -5V to -10V for optimal RDS(ON) and reliability, as characterized in the datasheet's electrical specifications table.
Can both channels be paralleled to increase current capacity?
No-parallel operation is not recommended. The BSS84DW-7-F channels are not matched for RDS(ON) or thermal coupling, and unequal current sharing may cause thermal runaway. For higher current, select a single-channel MOSFET with appropriate rating (e.g., DMN3025LSD) instead of paralleling.
Does the SOT363 package support reflow soldering per J-STD-020?
Yes-the SOT363 package is rated for Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to unlimited floor life and standard Pb-free reflow profiles (peak temperature ≤260°C) without baking. Terminal plating meets MIL-STD-202 Method 208 for solderability.
