Product details
Overview
BUZ100S-E3045A from Vishay is an N-channel enhancement-mode MOSFET designed for high-efficiency DC-DC conversion in automotive and industrial power supplies. It features RDS(on) = 1.8 mΩ (at VGS = 10 V), continuous drain current ID = 120 A, and breakdown voltage VDS = 40 V, housed in a thermally enhanced TO-263 (D²PAK) package with exposed drain pad.
For engineers reviewing the BUZ100S-E3045A datasheet, BUZ100S-E3045A pinout, BUZ100S-E3045A application, or BUZ100S-E3045A equivalent, key selection criteria include low on-resistance at 10 V gate drive, SOA-rated pulsed current capability up to 480 A, and AEC-Q101 qualification for automotive-grade reliability under thermal cycling and humidity testing.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low conduction loss and fast switching transitions. Its gate threshold voltage VGS(th) ranges from 2.0 V to 4.0 V, enabling compatibility with standard 3.3 V and 5 V logic-level drivers while maintaining robust noise immunity.
The device supports unclamped inductive switching (UIS) with energy rating EAS = 470 mJ and exhibits typical gate charge Qg = 95 nC at VGS = 10 V, supporting high-frequency synchronous rectification in buck converters operating up to 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage for 12 V automotive battery rail and 24 V industrial bus applications. |
| RDS(on) @ VGS = 10 V | 1.8 mΩ - Enables <1.5 W conduction loss at 120 A DC, critical for high-current POL converters. |
| ID (continuous) | 120 A - Rated at TC = 25 °C with proper heatsinking; derates to 75 A at TC = 100 °C. |
| Qg | 95 nC - Determines gate driver power requirement and switching transition time in hard-switched topologies. |
| EAS | 470 mJ - Supports reliable operation during inductive load turn-off without external snubbers. |
| AEC-Q101 | Qualified - Validated for automotive underhood temperature cycling (-40 °C to +175 °C) and HTRB stress. |
Pinout & Package
Package: TO-263 (D²PAK), surface-mount, with exposed drain pad soldered to PCB thermal plane for optimal junction-to-board thermal resistance (RθJB = 0.95 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | Control terminal; requires ≤±20 V absolute max rating; Miller plateau occurs near 4.5 V. |
| Pin 2 (D) | Drain | Main power output node; electrically connected to exposed copper pad for thermal and current conduction. |
| Pin 3 (S) | Source | Reference node for gate drive; forms return path for load current and gate loop. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) with 10 V drive | 1.8 mΩ enables >96% efficiency in 12 V → 1 V/100 A point-of-load converters. |
| High pulsed current rating | 480 A (tp ≤ 10 ms) supports peak-load handling in engine control units and EPS systems. |
| Enhanced UIS ruggedness | 470 mJ single-pulse avalanche energy allows safe operation during transient overcurrent events. |
| Thermally optimized package | TO-263 with exposed drain reduces RθJA to 2.5 °C/W on 2-layer 1 oz Cu board with 10 cm² copper pour. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF1407PbF | RDS(on) = 4.0 mΩ @ 10 V; TO-220 package; no AEC-Q101 qualification. | Limited to non-automotive industrial use due to lack of automotive qualification and higher conduction loss. | Prefer BUZ100S-E3045A where thermal density and automotive compliance are required. |
| STL220N4F7AG | RDS(on) = 1.6 mΩ @ 10 V; DFN8 5×6 mm package; lower ID = 80 A (TC = 100 °C). | Better suited for space-constrained consumer power stages but lacks pulsed current headroom for automotive transients. | Select BUZ100S-E3045A when 480 A UIS and 120 A continuous current are mandatory. |
Compared with IRF1407PbF and STL220N4F7AG, BUZ100S-E3045A uniquely combines automotive qualification, lowest thermal resistance via TO-263, and highest pulsed current rating-making it optimal for safety-critical, high-power-density automotive and industrial switching nodes.

FAQ
What is the maximum allowable gate-source voltage for BUZ100S-E3045A?
The absolute maximum VGS rating is ±20 V. Operation beyond this risks irreversible gate oxide damage. Recommended gate drive is 10 V for full enhancement, with 4.5 V–5.0 V as the Miller plateau region where dV/dt immunity is most critical during switching transitions.
Does BUZ100S-E3045A require a gate resistor for stability?
Yes-a series gate resistor (typically 2.2 Ω to 10 Ω) is required to dampen parasitic oscillation and control di/dt during turn-on/turn-off. The device's Qg = 95 nC and low Ciss = 4,200 pF make it sensitive to layout-induced ringing without proper gate network design.
Can BUZ100S-E3045A be used in parallel configurations?
Yes, but only with matched devices and symmetrical PCB layout. Its positive temperature coefficient of RDS(on) above 100 °C enables current sharing; however, gate drive skew must be kept below 5 ns and source inductance balanced to avoid dynamic current imbalance during switching.
Is BUZ100S-E3045A RoHS and REACH compliant?
Yes-BUZ100S-E3045A meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including exemption 7a for lead in high-melting-temperature solder. Certificate of Compliance is available upon request from Aetrix Electronics.
