Product details
Overview
V10KM120DU-M3/I from Vishay General Semiconductor is a dual-die, high-current-density surface-mount Trench MOS Barrier Schottky rectifier in FlatPAK 5×6 package, rated for 120 V reverse voltage and 5 A average forward current per diode, with ultra-low 0.54 V forward voltage at 5 A and 125 °C - optimized for low-voltage, high-frequency DC/DC converters in automotive and industrial power supplies.
For engineers reviewing the V10KM120DU-M3/I datasheet, V10KM120DU-M3/I pinout, V10KM120DU-M3/I application, or V10KM120DU-M3/I equivalent, key selection criteria include its AEC-Q101-qualified variant availability (HM3 suffix), MSL Level 1 moisture sensitivity, 175 °C max junction temperature, and separated cathode configuration enabling independent diode control in synchronous rectification and polarity protection circuits.
Technical Context
This device integrates two independent Schottky diodes in a single FlatPAK 5×6 thermally enhanced package with matte tin-plated leads and dual thermal pads. Each diode features trench MOS architecture delivering low VF and high efficiency at high switching frequencies.
It operates across -40 °C to +175 °C junction temperature range, supports 100 A non-repetitive surge current per diode, and achieves RθJM = 3.0 °C/W (typ) when mounted on an infinite heatsink - critical for compact, high-power-density converter designs where thermal management is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 120 V - blocks up to 120 V reverse voltage without breakdown, suitable for 48 V and 60 V bus systems. |
| IF(AV) per diode | 5 A - delivers continuous 5 A DC forward current per diode at TA = 25 °C with recommended PCB pad area. |
| VF at IF = 5 A, TA = 125 °C | 0.62 V - enables <1.5 W conduction loss per diode at full load and elevated temperature, reducing thermal stress. |
| IFSM per diode | 100 A - withstands short-duration 8.3 ms surge currents, supporting robust start-up and fault handling in SMPS. |
| TJ max. | +175 °C - allows operation in under-hood automotive environments and sealed industrial enclosures without derating. |
| RθJA (per diode) | 100 °C/W - defines thermal limit in free-air mounting; requires copper pour or thermal vias for >1.5 A sustained operation. |
| Circuit configuration | Separated cathode - permits independent connection of each diode's cathode, essential for dual-output or interleaved converter topologies. |
Pinout & Package
Package: FlatPAK 5 × 6 mm surface-mount package with dual exposed thermal pads (pins 1–2 and 7–8), matte tin-plated leads, UL 94 V-0 molding compound, and MSL Level 1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 & 2 | Anode 1 | Input terminal for first Schottky diode; electrically isolated from Anode 2 (pins 3 & 4). |
| 3 & 4 | Anode 2 | Input terminal for second Schottky diode; enables dual-channel freewheeling or independent polarity protection. |
| 5 & 6 | Cathode 1 | Output terminal for first diode; separated from Cathode 2 (pins 7 & 8) to support asymmetric output configurations. |
| 7 & 8 | Cathode 2 | Output terminal for second diode; allows independent grounding or rail connection in dual-output DC/DC stages. |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOS Schottky technology | Enables 0.54 V VF at 5 A/125 °C - reduces conduction losses by ≥25 % vs. planar Schottky alternatives in same package. |
| AEC-Q101 qualification (HM3 variant) | Validated for automotive under-hood applications including engine control units and ADAS power modules. |
| FlatPAK 5×6 dual thermal pad layout | Provides 2× independent thermal paths (RθJM = 3.0 °C/W typ per diode), improving heat extraction over SO-8 or TO-252. |
| Separated cathode configuration | Supports flexible circuit routing - e.g., one cathode tied to ground, the other to a regulated rail in dual-output buck converters. |
| MSL Level 1, 260 °C reflow compatible | Eliminates pre-bake requirement and supports standard SMT assembly lines without moisture-related delamination risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V10KM120DUHM3/I | AEC-Q101 qualified; identical electrical specs and package; HM3 suffix denotes automotive qualification. | Required for automotive production programs needing PPAP documentation and extended temperature validation. | Select V10KM120DUHM3/I when automotive qualification is mandatory; otherwise V10KM120DU-M3/I suffices for industrial use. |
| SS10120CT-E3/57T | TO-277 package; higher VF (0.85 V @ 5 A); no AEC-Q101 option; RθJA ≈ 120 °C/W. | Limited to lower-power or cost-sensitive consumer-grade applications due to inferior thermal performance. | Choose only if legacy TO-277 footprint must be retained; avoid where thermal density or automotive compliance matters. |
Compared with V10KM120DUHM3/I, the V10KM120DU-M3/I offers identical performance but excludes automotive qualification - making it ideal for industrial and telecom applications where cost and lead time are prioritized. Versus SS10120CT-E3/57T, the V10KM120DU-M3/I delivers superior thermal resistance, lower VF, and smaller footprint - directly enabling higher power density and reliability in modern SMPS designs.

FAQ
What is the maximum junction temperature rating for the V10KM120DU-M3/I?
The V10KM120DU-M3/I has a maximum junction temperature (TJ max.) of +175 °C, verified per Vishay's datasheet revision 15-Jul-2025. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in Figure 1 confirm usable current capacity down to -40 °C ambient, and thermal impedance data supports thermal modeling using RθJM = 3.0 °C/W (typ) with infinite heatsink mounting. The V10KM120DU-M3/I must not exceed this TJ limit under any steady-state or transient condition.
Is the V10KM120DU-M3/I pin-compatible with the AEC-Q101-qualified V10KM120DUHM3/I?
Yes - the V10KM120DU-M3/I and V10KM120DUHM3/I share identical pinout, package dimensions (FlatPAK 5×6), electrical specifications, and thermal characteristics. The sole difference is automotive qualification: HM3 suffix indicates AEC-Q101 testing and PPAP-ready documentation. No PCB layout change is required when upgrading from V10KM120DU-M3/I to V10KM120DUHM3/I in existing designs targeting automotive release. The V10KM120DU-M3/I remains fully functional in those layouts.
What does "separated cathode" mean for the V10KM120DU-M3/I, and how does it affect circuit design?
"Separated cathode" means the V10KM120DU-M3/I provides two independent cathode terminals (pins 5–6 and 7–8), allowing each internal Schottky diode to be connected to different reference points - e.g., one cathode to ground and the other to a regulated 5 V rail. This enables dual-output buck converters, independent polarity protection paths, or interleaved freewheeling configurations. Unlike common-cathode dual diodes, the V10KM120DU-M3/I avoids shared current paths and voltage coupling, preserving regulation accuracy and fault isolation.
Does the V10KM120DU-M3/I require special PCB layout considerations for thermal performance?
Yes - the V10KM120DU-M3/I uses a FlatPAK 5×6 package with dual exposed thermal pads (pins 1–2 and 7–8). To achieve RθJA = 100 °C/W (typ), Vishay specifies a minimum copper pad area per thermal pad and recommends ≥4 thermal vias per pad connected to inner-layer ground planes. Insufficient copper or missing vias will raise junction temperature beyond safe limits at >2.5 A. The V10KM120DU-M3/I datasheet provides exact footprint dimensions and via placement guidance on page 4.
What is the reverse leakage current specification for the V10KM120DU-M3/I at 120 V and 125 °C?
At VR = 120 V and TA = 125 °C, the V10KM120DU-M3/I exhibits a maximum reverse leakage current (IR) of 1.6 mA per diode, as specified in the Electrical Characteristics table on page 2 of the datasheet. This value reflects worst-case behavior under high-temperature, high-voltage bias - critical for evaluating standby power loss in always-on systems. Typical IR at these conditions is lower (≈0.8 mA), but design margins must use the 1.6 mA max value for thermal and efficiency calculations involving the V10KM120DU-M3/I.
