Product details
Overview
BSS8402DWQ-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in SOT363 package, integrating an N-channel (60 V, 13.5 Ω @ 10 V) and P-channel (−50 V, 10 Ω @ −5 V) device for bidirectional switching. It delivers low gate threshold voltage (1.0–2.5 V for Q1; −0.8 to −2.0 V for Q2), fast switching (tD(ON) ≤ 20 ns), and AEC-Q101 qualification-used in automotive power management and analog signal routing.
For engineers reviewing the BSS8402DWQ-7 datasheet, BSS8402DWQ-7 pinout, BSS8402DWQ-7 application, or BSS8402DWQ-7 equivalent, key selection criteria include verified RDS(ON) at specified VGS, dual-channel thermal derating behavior, AEC-Q101 compliance documentation, and SOT363 layout compatibility with high-density PCBs.
Technical Context
This dual-MOSFET integrates a 2N7002-type N-channel and BSS84-type P-channel die in one monolithic SOT363 package. Each channel operates independently with separate gate, drain, and source terminals, enabling push-pull, level-shifting, and H-bridge half-bridge configurations without external isolation.
It supports rail-to-rail analog switching up to ±50 V, with guaranteed VGS(TH) matching across temperature (−55 °C to +150 °C) and low input capacitance (Ciss = 22–45 pF) to minimize drive loss in battery-powered interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS (Q1) | 60 V - supports 24 V automotive supply rails with 2.5× safety margin against transients |
| VDSS (Q2) | −50 V - enables reverse-polarity protection and bidirectional signal control in ±15 V systems |
| RDS(ON) (Q1) | 13.5 Ω @ VGS = 10 V - limits conduction loss to <1.5 mW at 115 mA load current |
| RDS(ON) (Q2) | 10 Ω @ VGS = −5 V - allows direct microcontroller-level drive without level shifters |
| ID (Q1/Q2) | 115 mA / −130 mA - sufficient for LED drivers, sensor biasing, and logic-level interface loads |
| Ciss | 22–45 pF - ensures <10 ns propagation delay with 25 Ω gate driver impedance |
| PD | 200 mW - requires no heatsink on FR-4 with 1″ × 0.85″ copper pad per Diodes' layout |
Pinout & Package
SOT363 surface-mount package: 6-pin, 2.2 mm × 2.1 mm × 1.0 mm body, matte tin-plated Alloy 42 leadframe, moisture sensitivity level 1, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (S1) | N-channel source | Common reference node for N-channel operation; tied to ground or low-side return path |
| 3 (D1) | N-channel drain | Switches positive-side loads up to 60 V; connects to VCC-side circuitry |
| 4 (D2) | P-channel drain | Switches negative-side or floating loads; connects to VEE/−VIN nodes |
| 5 (S2) | P-channel source | Common reference for P-channel; typically tied to VCC or high-side rail |
| 6 (G2) | P-channel gate | Accepts 0 to −5 V drive; threshold activates at −0.8 to −2.0 V for inverted logic control |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LVT-7 | Higher RDS(ON): 18 Ω (N) / 22 Ω (P) @ VGS = ±4.5 V; lower VDSS: ±40 V | Limited to 5 V logic systems; unsuitable for 12 V automotive transients | Select when cost-sensitive consumer designs require only 3.3 V drive and ≤40 V operation |
| NTJD4152PZ-1 | Lower RDS(ON): 6.5 Ω (N) / 8.5 Ω (P) @ VGS = ±4.5 V; no AEC-Q101 qualification | Not approved for automotive use; lacks PPAP documentation and IATF 16949 traceability | Select for industrial IoT gateways where higher efficiency outweighs automotive compliance requirements |
Compared with DMC2038LVT-7 and NTJD4152PZ-1, BSS8402DWQ-7 uniquely combines AEC-Q101 qualification, 60 V/−50 V breakdown margins, and verified thermal stability across −55 °C to +150 °C-making it the only option qualified for under-hood automotive power switching.

FAQ
Is BSS8402DWQ-7 pin-compatible with BSS8402DW-7?
Yes-both share identical SOT363 pinout, internal schematic, and electrical specifications. The "Q" suffix denotes AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing, with no physical or functional differences in pin assignment or layout.
What is the maximum continuous drain current at +100°C ambient?
At TA = +100°C, the N-channel (Q1) supports 73 mA and the P-channel (Q2) supports −130 mA continuously, based on thermal derating curves in DS30380 Rev. 23–2, page 2, with standard FR-4 PCB mounting.
Does BSS8402DWQ-7 support 3.3 V logic-level gate drive?
Yes-the N-channel VGS(TH) (1.0–2.5 V) and P-channel VGS(TH) (−0.8 to −2.0 V) ensure reliable turn-on with 3.3 V GPIO, though RDS(ON) increases to 7.5 Ω (Q1) and 15 Ω (Q2) at VGS = ±3.3 V per datasheet Figures 4 and 11.
How is moisture sensitivity handled for BSS8402DWQ-7?
BSS8402DWQ-7 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/85% RH without baking prior to reflow, simplifying SMT assembly for high-volume automotive production lines.
