Product details
Overview
V5NM153-M3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN3820A package, rated for 150 V reverse voltage and 5 A average forward current, with low 0.56 V forward voltage at 2.5 A and 125 °C junction temperature-optimized for DC/DC converters and polarity protection in space-constrained power stages.
For engineers reviewing the V5NM153-M3/I datasheet, V5NM153-M3/I pinout, V5NM153-M3/I application, or V5NM153-M3/I equivalent, key selection criteria include its MSL Level 1 rating, side-wettable flanks for AOI compatibility, AEC-Q101-qualified variant availability (V5NM153HM3/I), and thermal resistance of 135 °C/W (junction-to-ambient, FR4, 2 oz).
Technical Context
This TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and reduced switching losses versus planar Schottky diodes, enabling higher efficiency in high-frequency (>100 kHz) DC/DC topologies. Its single-cathode/anode configuration supports unidirectional conduction with no recovery charge, eliminating reverse recovery loss.
The DFN3820A package delivers low profile (0.88 mm typical height) and enhanced thermal performance via direct die-to-pad mounting, with RθJM = 5 °C/W (typical) enabling effective heat transfer to the PCB copper pour. Polarity is marked by a color band on the cathode end.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - blocks up to 150 V reverse voltage without breakdown, suitable for 12 V–48 V bus systems with margin |
| IF(AV) | 5 A - continuous forward current capability with infinite heatsink; derates to 1.9 A in free air on standard FR4 |
| VF @ 2.5 A, 125 °C | 0.56 V - enables <1.4 W conduction loss at 2.5 A, critical for thermally constrained point-of-load designs |
| IFSM | 100 A - withstands short-duration surge currents (8.3 ms half-sine), supporting inrush and fault tolerance |
| TJ max | 175 °C - extended junction temperature range allows operation in under-hood automotive or industrial ambient environments |
| RθJA | 135 °C/W - thermal resistance to ambient on FR4 (2 oz), defines required PCB copper area for thermal management |
| CJ | 290 pF @ 4 V - low junction capacitance minimizes switching loss and EMI in high-frequency PWM applications |
Pinout & Package
Package: DFN3820A - leadless, halogen-free, RoHS-compliant, side-wettable flanks for automated optical inspection (AOI); dimensions 3.95 mm × 2.18 mm × 0.88 mm (L × W × H); matte tin-plated terminals, JESD 201 Class 2 whisker tested.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry terminal | Connected to input/source side; must be routed with low-inductance path for high-di/dt stability |

Key Features
| Feature | Design Value |
|---|---|
| Trench MOS Schottky technology | Reduces forward voltage drop by ~15–20% vs. planar Schottky at same current, directly lowering conduction loss |
| Side-wettable flanks | Enables reliable solder joint inspection using AOI without X-ray, improving manufacturing yield in high-volume SMT lines |
| MSL Level 1 (260 °C peak) | Allows standard reflow profiles without baking or special handling, reducing production overhead and moisture sensitivity risk |
| AEC-Q101 qualified option (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD, supporting under-hood use cases |
| Low profile (0.88 mm typical height) | Enables ultra-thin power modules and portable electronics where Z-height is constrained below 1.0 mm |
Applications
| DC/DC Converters | Polarity Protection |
|---|---|
Use Scenario: Synchronous buck converter output stage in telecom power supplies operating at 300–500 kHz. IC Role / Device Role / Timing Role: Freewheeling rectifier replacing body diode of low-side MOSFET to reduce conduction loss and improve efficiency. Use Value: 0.56 V VF at 125 °C cuts conduction loss by ~30% vs. standard Schottky, raising full-load efficiency from 92% to 94.5%. |
Use Scenario: Reverse-voltage protection for USB-C PD power inputs in industrial gateways. IC Role / Device Role / Timing Role: Series-connected anode-in configuration blocking reverse polarity up to 150 V. Use Value: Low 0.70 V VF at 25 °C limits voltage drop to <0.7 V at 5 A, preserving >94% input voltage under full load. |
| High-Frequency Inverters | Freewheeling Diodes |
Use Scenario: Auxiliary power supply in motor drive inverters switching at 20–40 kHz. IC Role / Device Role / Timing Role: Output rectifier in flyback or resonant LLC secondary stage. Use Value: 290 pF CJ minimizes capacitive turn-on loss and EMI generation during hard-switched transitions. |
Use Scenario: Snubberless freewheeling path across inductive loads in solenoid drivers. IC Role / Device Role / Timing Role: Unidirectional clamp providing zero-recovery-path for stored inductor energy. Use Value: Absence of reverse recovery charge eliminates voltage spikes and reduces snubber component count and board area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V5NM153HM3/I | AEC-Q101 qualified; identical electrical specs and package; differs only in qualification testing and traceability documentation | Required for automotive OEM designs; not needed for commercial/industrial applications | Select V5NM153HM3/I when automotive PPAP, lot traceability, or HTOL validation is mandated |
| SS5P15L-M3/84A | Same 150 V/5 A rating but planar Schottky; VF = 0.82 V @ 2.5 A, 25 °C; higher RθJA = 180 °C/W | Limited to lower-frequency (<100 kHz), less thermally demanding applications due to higher loss and thermal resistance | Choose SS5P15L-M3/84A only if cost sensitivity outweighs efficiency and thermal performance requirements |
Compared with V5NM153-M3/I, the V5NM153HM3/I adds automotive qualification without altering electrical behavior, while the SS5P15L-M3/84A trades 0.26 V higher forward voltage and 45 °C/W worse thermal resistance for lower unit cost in non-demanding applications.

FAQ
What is the maximum junction temperature rating for the V5NM153-M3/I?
The V5NM153-M3/I has a maximum junction temperature (TJ) of +175 °C, verified per JEDEC standards and supported by its thermal design with RθJM = 5 °C/W. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. The V5NM153-M3/I must be mounted on adequate PCB copper area to maintain TJ ≤ 175 °C under worst-case power dissipation.
Is the V5NM153-M3/I pin-compatible with other DFN3820A Schottky rectifiers?
Yes-the V5NM153-M3/I uses the standardized DFN3820A footprint (3.95 mm × 2.18 mm) with anode and cathode terminals in identical positions to industry-standard variants. Its side-wettable flanks and terminal plating comply with J-STD-002, ensuring solder compatibility and mechanical interoperability with other DFN3820A rectifiers like SS5P15L-M3/84A, though electrical performance differs.
Does the V5NM153-M3/I meet automotive qualification requirements?
The base V5NM153-M3/I is commercial-grade and RoHS-compliant but not AEC-Q101 qualified. However, the functionally identical V5NM153HM3/I variant carries full AEC-Q101 qualification-including stress testing for temperature cycling, HTRB, and ESD-with identical electrical specs and DFN3820A packaging. For automotive use, specify V5NM153HM3/I instead of V5NM153-M3/I.
What is the forward voltage of the V5NM153-M3/I at 5 A and 125 °C?
Per the Vishay datasheet (Doc #98377), the V5NM153-M3/I exhibits a maximum forward voltage of 0.68 V at IF = 5 A and TJ = 125 °C. At the same current and 25 °C, VF is 0.97 V max. This temperature-dependent reduction confirms the device's stable performance across its full operating range and supports accurate thermal modeling in the V5NM153-M3/I design.
How does the V5NM153-M3/I compare to traditional planar Schottky diodes in efficiency?
The V5NM153-M3/I achieves up to 20% lower forward voltage than comparable planar Schottky diodes (e.g., SS5P15L-M3/84A) at 2.5 A and 125 °C-0.56 V vs. 0.68 V-directly reducing conduction loss. Combined with zero reverse recovery charge (Qrr = 0), it eliminates switching loss components present in planar devices, making the V5NM153-M3/I measurably more efficient in high-frequency DC/DC and inverter applications.
