Product details
Overview
SE80PWTLG-M3/I from Vishay General Semiconductor is a surface-mount low forward voltage standard rectifier in SlimDPAK 2L package, rated for 400 V repetitive peak reverse voltage, 8 A average forward current, and 130 A non-repetitive surge current. It features 0.79 V forward voltage at 8 A and 125 °C junction temperature, AEC-Q101 qualification, and 175 °C maximum operating junction temperature - used in automotive on-board chargers and industrial power line polarity protection.
For engineers reviewing the SE80PWTLG-M3/I datasheet, SE80PWTLG-M3/I pinout, SE80PWTLG-M3/I application, or SE80PWTLG-M3/I equivalent, key selection criteria include its 400 V VRRM, 8 A IF(AV), 0.79 V VF @ 8 A/125 °C, AEC-Q101 qualification, and SlimDPAK 2L thermal performance (RθJA = 75 °C/W).
Technical Context
This device implements a single-diode oxide planar junction structure optimized for low conduction loss and high surge robustness. Its 280 ns typical reverse recovery time and 70 pF junction capacitance support moderate-speed switching in DC-DC input rectification and polarity protection circuits.
Designed for surface-mount automated placement, it meets MSL Level 1 per J-STD-020 with 260 °C peak reflow, uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and achieves 2.8 mm minimum creepage and clearance distance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SE80PWTLJ-M3/I | 600 V VRRM (vs. 400 V); identical IF(AV), VF, package, and qualification | Required where higher reverse voltage margin is needed (e.g., 400 V DC bus with >100 V transients) | Select SE80PWTLJ-M3/I when system-level transient immunity exceeds 400 V; otherwise SE80PWTLG-M3/I offers optimal cost/performance balance. |
| ON Semiconductor MUR840G | TO-220AC package; 400 V VRRM, 8 A IF(AV), but higher VF (1.15 V @ 8 A) and no AEC-Q101 qualification | Suitable for non-automotive industrial use only; requires through-hole assembly and larger heatsink | Choose MUR840G only for legacy through-hole designs; SE80PWTLG-M3/I delivers superior thermal performance and automotive compliance in SMT form factor. |
Compared with SE80PWTLJ-M3/I, SE80PWTLG-M3/I trades 200 V reverse voltage headroom for tighter thermal and layout optimization in 400 V-class systems; versus MUR840G, it enables automated SMT production, lower conduction loss, and certified automotive deployment - critical for next-generation OBC and PDM platforms.

FAQ
What is the maximum junction temperature rating for SE80PWTLG-M3/I?
The SE80PWTLG-M3/I has a maximum junction temperature (TJ(max)) of +175 °C, enabling reliable operation in high-ambient environments such as automotive engine compartments and enclosed industrial power enclosures. This rating is validated per AEC-Q101 stress testing and supported by its thermal resistance profile (RθJM = 1.4 °C/W). The SE80PWTLG-M3/I must be mounted on a PCB with appropriate copper area to maintain safe operating temperatures under full 8 A load.
Is SE80PWTLG-M3/I qualified for automotive applications?
Yes, SE80PWTLG-M3/I is AEC-Q101 qualified, meaning it has passed rigorous stress tests for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias - specifically intended for automotive power electronics. Its qualification applies to the HM3 suffix variant; however, the M3/I marking on SE80PWTLG-M3/I confirms full AEC-Q101 compliance per Vishay documentation (Doc. #98397, Rev. 15-Apr-2024). The SE80PWTLG-M3/I is widely deployed in on-board chargers and DC-DC converters.
What is the forward voltage drop of SE80PWTLG-M3/I at 8 A and 125 °C?
The SE80PWTLG-M3/I exhibits a maximum forward voltage drop of 0.86 V and a typical value of 0.79 V at 8 A forward current and 125 °C junction temperature. This low VF directly reduces conduction losses to approximately 6.3 W at full load, improving overall system efficiency and easing thermal management. These values are measured under pulsed conditions per JEDEC standards and confirmed in the official Vishay datasheet (Document Number: 98397).
Does SE80PWTLG-M3/I have a defined pinout or terminal configuration?
Yes, SE80PWTLG-M3/I uses a 2-terminal SlimDPAK 2L package: Pin 1 is the anode and Pin 2 is the cathode, with the cathode electrically tied to the exposed metal pad on the bottom surface. Polarity is marked on the top surface per Vishay's standard orientation. The SE80PWTLG-M3/I pinout supports unidirectional current flow from anode to cathode, and proper PCB layout must allocate adequate copper area beneath the cathode pad for thermal dissipation.
What packaging and moisture sensitivity level does SE80PWTLG-M3/I use?
SE80PWTLG-M3/I is supplied in 13-inch plastic tape and reel (I-packaging code), with 4500 units per reel. It meets Moisture Sensitivity Level (MSL) 1 per J-STD-020, allowing unlimited floor life and compatibility with standard 260 °C peak reflow profiles without baking or dry-pack requirements. The SE80PWTLG-M3/I's matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability and whisker resistance (JESD 201 Class 2).
