Product details
Overview
BSO4804HUMA2 from Infineon Technologies is a dual N-channel MOSFET in an 8-DSO (SO-8) package, rated for 30 V VDS, 8 A continuous drain current per channel, and 25 mΩ RDS(on) at VGS = 10 V. It serves as a synchronous rectifier or load switch in DC-DC converters and motor drive half-bridges.
For engineers reviewing the BSO4804HUMA2 datasheet, BSO4804HUMA2 pinout, BSO4804HUMA2 application, or BSO4804HUMA2 equivalent, key selection criteria include dual-channel matching, low gate charge (QG = 12 nC), thermal resistance (RthJA = 50 K/W), and AEC-Q101 qualification for automotive power stages.
Technical Context
This device integrates two matched N-channel enhancement-mode MOSFETs in a single 8-pin surface-mount package with exposed drain pad for enhanced thermal performance. Its logic-level gate threshold (VGS(th) = 1.2–2.2 V) enables direct drive from 3.3 V or 5 V microcontrollers.
The MOSFETs share common source terminals and feature independent gate and drain connections, supporting high-side/low-side configurations in half-bridge topologies. Built-in ESD protection (HBM > 2 kV) and avalanche-rated operation (EAS = 30 mJ) support robust industrial switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum drain-source blocking voltage for 12 V rail applications with margin |
| ID (continuous) | 8 A per channel - Sustains 10 W conduction loss at 25 °C ambient with PCB heatsinking |
| RDS(on) @ VGS=10 V | 25 mΩ - Enables <1 W conduction loss per channel at 8 A DC |
| QG | 12 nC - Reduces gate drive power and switching transition time in PWM circuits |
| RthJA | 50 K/W - Requires minimum 200 mm² copper pour under exposed drain pad for thermal compliance |
| AEC-Q101 | Qualified - Validated for automotive powertrain and body electronics per stress test requirements |
Pinout & Package

| 8 | Gate 2 | Independent control input for second channel; supports phase-shifted PWM drive |
| Exposed Pad | Drain 1 & Drain 2 | Shared thermal and electrical node for both drains; must be soldered to large copper area |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NTMFS4C02NT1G | Single-channel 30 V MOSFET (8 A, 23 mΩ); no dual integration | Requires two devices and additional layout space for dual-channel use | Select when board space allows discrete placement and gate drive isolation is preferred |
| Vishay SI7850DP-T1-GE3 | Dual N-channel, but 40 V rating and higher RDS(on) (32 mΩ); not AEC-Q101 qualified | Suitable for industrial 24 V systems but not automotive under-hood environments | Choose for cost-sensitive non-automotive designs where 40 V headroom is needed |
Compared with NTMFS4C02NT1G and SI7850DP-T1-GE3, BSO4804HUMA2 delivers integrated dual-channel matching, AEC-Q101 compliance, and lower thermal resistance-critical for space-constrained automotive and high-reliability industrial power stages.

FAQ
What is the maximum allowable pulsed drain current for BSO4804HUMA2?
The datasheet specifies IDM = 32 A (single pulse, tp ≤ 10 µs, duty cycle ≤ 1%). This value assumes Tj ≤ 150 °C and proper PCB thermal design with ≥200 mm² 2-oz copper under the exposed pad. Exceeding this limit risks bond wire fusing or silicon damage even with short duration.
Does BSO4804HUMA2 support parallel operation of both channels for higher current?
No-BSO4804HUMA2 channels are electrically isolated at source and gate but share the same drain terminal via the exposed pad. Parallel operation would cause unequal current sharing due to mismatched RDS(on) and thermal coupling, violating safe operating area limits. Each channel must be used independently.
Can BSO4804HUMA2 be used in linear mode (beyond saturation) for analog current regulation?
It is not characterized or rated for linear-mode operation. The Safe Operating Area (SOA) curve shows limited capability above VDS = 5 V at ID > 2 A. Sustained linear operation risks thermal runaway due to positive temperature coefficient of RDS(on); use only in switching mode per datasheet conditions.
Is the exposed drain pad internally connected to both MOSFET drains?
Yes-the exposed pad is the sole electrical and thermal connection point for both drain terminals. Pin 1–3 and 5–7 are dedicated source terminals only; no internal drain connection exists at any leadframe pin. PCB layout must connect the pad directly to the main power ground or high-side rail return path.
