Product details
Overview
SE80PWTLGHM3/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 (VRRM), 8 A average forward current (IF(AV)), and 130 A non-repetitive surge current (IFSM). It features AEC-Q101 qualification, 175 °C maximum junction temperature, and 0.79 V forward voltage at 8 A and 125 °C - optimized for automotive on-board charger (OBC) polarity protection.
For engineers reviewing the SE80PWTLGHM3/I datasheet, SE80PWTLGHM3/I pinout, SE80PWTLGHM3/I application, or SE80PWTLGHM3/I equivalent, key selection criteria include its SlimDPAK 2L footprint compatibility, low-profile 1.3 mm height, MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction with matte tin-plated leads.
Technical Context
This device is a single-diode, oxide planar junction rectifier designed for high-efficiency DC power conversion in constrained thermal environments. Its low VF (0.79 V @ 8 A, 125 °C) reduces conduction loss, while RθJA of 75 °C/W (typ.) enables operation up to 175 °C junction temperature under defined PCB copper pad conditions.
The SE80PWTLGHM3/I uses a SlimDPAK 2L package with creepage and clearance ≥2.8 mm, meets JESD201 Class 2 whisker resistance, and is qualified per AEC-Q101 for automotive applications - distinguishing it from industrial-grade variants like SE80PWTLG-M3/I that lack automotive qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification in 300–400 V DC bus systems, including OBC front-end stages. |
| IF(AV) | 8 A - delivers continuous output current with thermal derating above 25 °C ambient, per Fig. 1 curve. |
| VF @ 8 A, 125 °C | 0.79 V - minimizes power loss (6.32 W conduction loss at full load), critical for thermal management in sealed enclosures. |
| IFSM | 130 A - withstands inrush surges during system startup without degradation, per 8.3 ms half-sine waveform. |
| TJ max | 175 °C - enables reliable operation in under-hood automotive environments where ambient exceeds 105 °C. |
| RθJA (typ.) | 75 °C/W - defines required PCB copper area (per JEDEC 51-2A) to maintain safe junction temperature at rated load. |
| trr (typ.) | 280 ns - limits switching losses in moderate-frequency rectification (e.g., <100 kHz PFC stages). |
Pinout & Package
Package: SlimDPAK 2L - ultra-low-profile surface-mount package (1.3 mm typical height), 2-terminal configuration, halogen-free, RoHS-compliant, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Connected to input source side in polarity protection; requires thermal pad routing for heat dissipation. |
| 2 (Cathode) | Cathode connection | Connected to load/ground side; marked "K" on top silkscreen; carries full forward current path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity bias, and mechanical shock per stress test requirements. |
| Creepage/clearance ≥2.8 mm | Meets reinforced insulation requirements for 400 V DC systems, reducing risk of arcing in humid or contaminated environments. |
| Very low profile (1.3 mm) | Enables integration into space-constrained modules such as compact OBC inverters and battery management subassemblies. |
| Oxide planar chip junction | Ensures stable reverse leakage (<5 μA @ 25 °C) and predictable trr performance across temperature and lifetime. |
| MSL Level 1, 260 °C peak reflow | Compatible with standard lead-free SMT reflow profiles without preconditioning or special handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SE80PWTLJHM3/I | 600 V VRRM (vs. 400 V), identical package, thermal specs, and AEC-Q101 qualification. | Suitable for higher-input-voltage OBC designs (e.g., 800 V nominal systems with 600 V rectifier margin). | Select when system DC bus exceeds 450 V or requires additional reverse voltage safety margin. |
| ON Semiconductor MUR840CT-T | TO-220AC package, 400 V VRRM, 8 A IF(AV), but no AEC-Q101 qualification and 1.8 mm height. | Limited to industrial/non-automotive applications; incompatible with SlimDPAK footprint and low-profile constraints. | Use only if board layout permits larger through-hole or TO-220 footprint and automotive qualification is not required. |
Compared with SE80PWTLJHM3/I, the SE80PWTLGHM3/I offers lower VRRM but identical thermal, mechanical, and automotive qualifications - making it optimal for cost-sensitive 400 V OBCs. Versus MUR840CT-T, it delivers superior board-level integration, reliability in automotive environments, and reduced assembly cost via SMT compatibility.

FAQ
What is the AEC-Q101 qualification status of the SE80PWTLGHM3/I?
The SE80PWTLGHM3/I is fully AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number: 98397, Revision: 15-Apr-2024). This includes stress testing for temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for automotive power electronics such as on-board chargers and battery disconnect units. The HM3 suffix explicitly denotes AEC-Q101 compliance.
Does the SE80PWTLGHM3/I have the same pinout as SE80PWTLJHM3/I?
Yes, the SE80PWTLGHM3/I and SE80PWTLJHM3/I share identical SlimDPAK 2L pinout, terminal configuration, and mechanical dimensions - both feature Anode (Pin 1) and Cathode (Pin 2) with "K" marking on the top surface. Their electrical difference lies solely in VRRM (400 V vs. 600 V); all thermal, packaging, and qualification specs are matched.
What is the maximum recommended PCB copper pad area for thermal performance of SE80PWTLGHM3/I?
Vishay specifies thermal resistance RθJA = 75 °C/W (typ.) for the SE80PWTLGHM3/I when mounted on an FR4 PCB with 2 oz. copper and the recommended mounting pad layout (Document 98397, page 4). While exact pad area isn't numerically prescribed, the provided outline shows a 4.50 mm × 5.70 mm thermal pad - underscoring that full thermal pad exposure beneath the package base is essential to achieve rated IF(AV) at elevated ambient temperatures.
Is the SE80PWTLGHM3/I compatible with lead-free reflow soldering processes?
Yes, the SE80PWTLGHM3/I is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C - fully compatible with standard lead-free soldering profiles. Its matte tin-plated leads meet J-STD-002 and JESD22-B102 solderability requirements, and it passes JESD201 Class 2 whisker testing, ensuring long-term interconnect integrity.
How does the forward voltage of SE80PWTLGHM3/I compare at different junction temperatures?
The SE80PWTLGHM3/I exhibits a negative temperature coefficient for forward voltage: VF = 0.91 V (max) at 8 A and 25 °C, dropping to 0.79 V (typ.) at 8 A and 125 °C. This behavior reduces conduction loss at elevated operating temperatures - a key advantage in thermally dense automotive modules where junction temperatures routinely exceed 100 °C during sustained operation.
