Product details
Overview
SIR582DP-T1-BE3 from Vishay Siliconix is an N-channel 80 V (D-S) TrenchFET® Gen V power MOSFET in PowerPAK® SO-8 package, delivering RDS(on) = 3.4 mΩ at VGS = 10 V, Qg = 33.5 nC (typ.), and continuous drain current ID = 116 A (TC = 25 °C), optimized for high-efficiency synchronous rectification and DC/DC converter primary-side switching.
For engineers reviewing the SIR582DP-T1-BE3 datasheet, SIR582DP-T1-BE3 pinout, SIR582DP-T1-BE3 application, or SIR582DP-T1-BE3 equivalent, this page provides verified thermal resistance (RthJC = 1.1 °C/W typ.), body diode recovery characteristics (trr = 67 ns typ., Qrr = 88 nC), and absolute maximum ratings including VGS = ±20 V and TJ = -55 to +150 °C - all critical for power stage layout, thermal design, and reliability validation.
Technical Context
This MOSFET employs trench-gate silicon technology with optimized charge distribution to achieve a low RDS(on) × Qoss figure-of-merit, targeting reduced switching losses in hard-switched topologies. Its gate threshold voltage VGS(th) ranges from 2 V to 4 V at ID = 250 μA, enabling robust turn-on control with standard 7.5 V or 10 V gate drivers.
The device integrates a fast, low-VSD body diode (VSD = 0.75 V typ. at IS = 5 A, VGS = 0 V) and is 100 % Rg and UIS tested. Thermal performance is characterized with RthJC = 1.1 °C/W (max 1.35 °C/W) and RthJA = 18 °C/W (t ≤ 10 s), supporting high-power density designs on FR4 PCBs with minimal heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 80 V - Maximum drain-source blocking voltage; defines safe operating range in 48 V and 60 V bus applications. |
| RDS(on) max @ VGS = 10 V | 3.4 mΩ - Conduction loss of ~0.4 W at 116 A; enables high-current, low-voltage-drop switching in power stages. |
| Qg typ. @ VGS = 7.5 V | 33.5 nC - Gate drive energy requirement; determines driver sizing and switching loss in 100–500 kHz converters. |
| ID continuous @ TC = 25 °C | 116 A - Package-limited current capacity; requires direct thermal path to copper plane or heatsink for sustained operation. |
| RthJC typical | 1.1 °C/W - Junction-to-case thermal resistance; enables accurate junction temperature prediction when mounted on thermally enhanced pads. |
| trr typ. | 67 ns - Body diode reverse recovery time; critical for minimizing shoot-through risk and EMI in synchronous buck or LLC resonant converters. |
| VGS(th) | 2–4 V - Gate threshold voltage range; ensures reliable turn-on with 5 V logic-level drivers and avoids false triggering near ground. |
Pinout & Package
Package: PowerPAK® SO-8 (leadless, exposed-drain thermal pad). Dimensions: 6.15 mm × 5.15 mm × 1.04 mm (L × W × H). Bottom-side copper drain pad enhances thermal conduction and current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Four parallel source terminals reduce source inductance and improve current sharing in high-di/dt switching. |
| 5, 6, 7, 8 | Drain (D) | Four parallel drain terminals connected to large bottom-side thermal pad; primary current return path and heat sink interface. |
| G (Gate) | Control input | Single gate terminal located at Pin 1 side; requires low-inductance routing to minimize ringing during fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| TrenchFET® Gen V architecture | Optimized cell pitch and trench depth yield lowest RDS(on) × Qoss FOM for reduced switching loss in high-frequency DC/DC stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 80 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiR626DP-T1-RE3 | RDS(on) = 2.8 mΩ @ 10 V (lower), Qg = 44.5 nC (higher), same PowerPAK SO-8 package. | Better conduction loss but higher gate drive demand; suited for lower-frequency, high-current apps where switching loss is secondary. | Select SiR626DP-T1-RE3 when optimizing for <100 kHz operation with peak ID > 130 A; SIR582DP-T1-BE3 preferred for 200–600 kHz with balanced loss trade-off. |
| IRF6642TRPBF | RDS(on) = 3.2 mΩ @ 10 V, Qg = 27 nC, PQFN 5×6 mm package; no exposed drain pad. | Lower Qg improves high-frequency efficiency but lacks thermal performance: RthJC = 2.0 °C/W vs. 1.1 °C/W for SIR582DP-T1-BE3. | Choose IRF6642TRPBF for space-constrained layouts needing minimal footprint; SIR582DP-T1-BE3 when thermal management dominates board-level design. |
Compared with SiR626DP-T1-RE3 and IRF6642TRPBF, the SIR582DP-T1-BE3 offers the optimal balance of low RDS(on), moderate Qg, and industry-leading RthJC, making it especially suitable for thermally demanding, medium-to-high-frequency power conversion where both conduction and switching losses must be tightly controlled.

FAQ
What is the maximum continuous drain current rating for SIR582DP-T1-BE3 at case temperature of 70 °C?
The SIR582DP-T1-BE3 supports 93 A continuous drain current at TC = 70 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the PowerPAK SO-8 package and must be validated against actual board-level thermal resistance and ambient conditions. The SIR582DP-T1-BE3 datasheet confirms this value under steady-state conditions with proper PCB copper area.
Does SIR582DP-T1-BE3 have an integrated body diode, and what are its key recovery parameters?
Yes, the SIR582DP-T1-BE3 includes a built-in body diode with trr = 67 ns (typ.) and Qrr = 88 nC (typ.) at IF = 10 A, dI/dt = 100 A/μs, and TJ = 25 °C. These values are measured and guaranteed per datasheet Section 1, enabling accurate dead-time optimization in synchronous rectifier designs using the SIR582DP-T1-BE3.
What is the gate threshold voltage range for SIR582DP-T1-BE3, and how does it affect driver compatibility?
The SIR582DP-T1-BE3 has a gate threshold voltage VGS(th) of 2 V to 4 V at ID = 250 μA, ensuring compatibility with standard 5 V and 7.5 V gate drivers while avoiding unintended turn-on near ground. This range is confirmed in the "Specifications" table of the SIR582DP-T1-BE3 datasheet and supports robust noise immunity in noisy power environments.
Is SIR582DP-T1-BE3 suitable for avalanche-rated applications, and what is its single-pulse energy rating?
Yes, the SIR582DP-T1-BE3 is 100 % UIS tested and rated for single-pulse avalanche energy EAS = 80 mJ with L = 0.1 mH, as stated in its Absolute Maximum Ratings. This makes the SIR582DP-T1-BE3 appropriate for applications subject to inductive switching transients, such as motor drives and hot-swap controllers, where unclamped energy must be safely absorbed.
What is the thermal resistance from junction to case (RthJC) for SIR582DP-T1-BE3, and how is it used in thermal design?
The SIR582DP-T1-BE3 has a typical junction-to-case thermal resistance RthJC of 1.1 °C/W, with a maximum of 1.35 °C/W. This parameter is used to calculate junction temperature rise above the case (ΔTJC = PD × RthJC) and is essential for validating thermal margin when mounting the SIR582DP-T1-BE3 on PCBs with defined copper area and thermal vias.
