Product details
Overview
S07G-M-18 from Vishay Semiconductors is a standard recovery surface-mount rectifier diode in the eSMP® Series, rated for 400 V repetitive peak reverse voltage (VRRM), 1.5 A average forward current at TL = 110 °C, and 1.1 V forward voltage at 1 A. It features glass passivation, SOD-123W-compatible SMF (DO-219AB) packaging, and AEC-Q101 qualification for automotive-grade reliability in high-voltage DC power supplies.
For engineers reviewing the S07G-M-18 datasheet, S07G-M-18 pinout, S07G-M-18 application, or S07G-M-18 equivalent, key selection criteria include its 400 V blocking capability, 1800 ns reverse recovery time, low-profile SMF package with cathode band marking, and suitability for automated SMT assembly in space-constrained industrial and automotive power converters.
Technical Context
The S07G-M-18 is a single-die, single-anode/cathode standard recovery rectifier optimized for high-voltage, medium-current AC/DC front-end and output rectification. Its 1800 ns reverse recovery time and 4 pF junction capacitance reflect trade-offs favoring low leakage and thermal robustness over ultrafast switching.
Designed for operation up to +175 °C junction temperature and qualified per AEC-Q101, the device uses glass-passivated silicon die in a low-profile SMF (DO-219AB) case with MSL Level 1 moisture sensitivity and wave/reflow solder compatibility - enabling use in harsh-environment automotive and industrial power modules without derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification from 280 VRMS AC lines or 400 V DC bus applications without breakdown risk. |
| IF(AV) | 1.5 A at TL = 110 °C - enables compact heatsink-free designs in ambient-temperature-limited power supplies. |
| VF | 1.1 V at IF = 1 A - limits conduction loss to ~1.1 W at 1 A, supporting thermally efficient linear or low-frequency switching topologies. |
| trr | 1800 ns - suitable for line-frequency (50/60 Hz) and low-kHz switching applications; not intended for >100 kHz SMPS. |
| RthJA | 180 K/W - requires careful PCB copper area design (e.g., 3 mm × 3 mm Cu pads ≥40 μm thick) to maintain safe junction temperature. |
| IR | 10 μA at 25 °C, 50 μA at 125 °C - ensures minimal leakage in high-impedance hold-up or sensing circuits across temperature range. |
| Cj | 4 pF at 4 V, 1 MHz - reduces high-frequency noise coupling and EMI in snubberless or lightly filtered rectifier stages. |
Pinout & Package
Package: SMF (DO-219AB), low-profile surface-mount case with cathode indicated by molded band; compatible with SOD-123W footprint and reflow/wave soldering per J-STD-020 MSL Level 1 (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive input terminal for forward conduction | Connected to AC source or transformer secondary; must withstand full reverse voltage when cathode is biased higher. |
| Cathode | Negative output terminal; marked with band | Delivers rectified DC output; polarity-sensitive placement required for correct circuit function and thermal path routing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control units and body electronics requiring extended temperature and reliability compliance. |
| Glass passivated junction | Provides stable reverse leakage and long-term reliability against humidity and contamination in unsealed industrial enclosures. |
| SMF (DO-219AB) package | 0.85 mm height enables ultra-thin power supply designs; 15 mg weight supports vibration-resistant mounting in transportation systems. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declarations for environmentally regulated end equipment. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay S07G-M3-18 | Halogen-free variant (base P/N-M3); identical electrical specs and SMF package; same AEC-Q101 qualification. | No functional difference; selected where halogen-free material declaration is mandatory per IPC-1752A or customer sustainability policy. | Choose S07G-M3-18 if RoHS + halogen-free compliance is contractually required; otherwise S07G-M-18 satisfies standard automotive/industrial needs. |
| ON Semiconductor MUR120RLG | Higher VRRM (200 V), faster trr (75 ns), TO-220AC package; 1.5 A IF(AV) at TC = 110 °C, not AEC-Q101 qualified. | Requires heatsink and through-hole assembly; suited for higher-frequency, lower-voltage SMPS where fast recovery reduces switching loss. | Select MUR120RLG only when faster recovery and higher thermal mass are needed; S07G-M-18 remains optimal for SMT, space-constrained, AEC-Q101–required designs. |
Compared with S07G-M3-18, the S07G-M-18 offers identical performance with standard halogen-free compliance, while MUR120RLG trades SMT compatibility and automotive qualification for faster recovery and higher thermal capacity - making S07G-M-18 the preferred choice for AEC-Q101–mandated, low-profile, automated production environments.

FAQ
What is the maximum junction temperature rating for the S07G-M-18?
The S07G-M-18 has an operating junction temperature range of −65 °C to +175 °C, verified per Vishay Document Number 85191 Rev. 1.8. This wide range enables deployment in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 125 °C. The S07G-M-18 maintains specified electrical performance across this full range when mounted on appropriate PCB copper areas.
Is the S07G-M-18 pin-compatible with other devices in the S07x-M family?
Yes - all S07x-M devices (S07B-M, S07D-M, S07G-M, S07J-M, S07M-M) share identical SMF (DO-219AB) package dimensions, pinout, and thermal footprint. The S07G-M-18 can be substituted for other members in the family on the same PCB layout, provided voltage and current ratings meet system requirements. No layout changes are needed when upgrading from S07D-M-18 (200 V) to S07G-M-18 (400 V).
Does the S07G-M-18 require a heatsink in typical applications?
No - the S07G-M-18 is rated for 1.5 A average forward current at TL = 110 °C with no external heatsink, assuming mounting on 3 mm × 3 mm Cu pads ≥40 μm thick. Its RthJA of 180 K/W allows self-cooled operation in most SMT power supplies below 10 W output. A heatsink is unnecessary unless ambient temperature exceeds 85 °C or continuous load exceeds 1.2 A.
What does the "-18" suffix indicate in S07G-M-18?
The "-18" suffix denotes tape-and-reel packaging: 10,000 units per 13-inch reel using 8 mm carrier tape. This format is optimized for high-volume automated pick-and-place assembly. The alternative "-08" option provides 3,000 units per 7-inch reel. Both S07G-M-18 and S07G-M-08 share identical electrical, thermal, and mechanical specifications - only packaging differs.
How does the S07G-M-18 compare to ultrafast rectifiers like the MUR series?
The S07G-M-18 is a standard recovery rectifier with 1800 ns trr, optimized for line-frequency and low-kHz applications where low leakage and thermal robustness outweigh switching speed. Ultrafast rectifiers such as ON Semiconductor's MUR series offer trr < 100 ns but lack AEC-Q101 qualification and SMF packaging. For designs requiring both fast recovery and automotive qualification, the S07G-M-18 is not a direct replacement - it serves distinct application segments.
