Product details
Overview
VS-MBR1635-M3 from Vishay Semiconductors is a high-performance Schottky rectifier optimized for low reverse leakage at elevated temperatures, rated for 16 A average forward current and 35 V maximum DC reverse voltage, with 0.57 V forward voltage drop at 16 A and 125 °C junction temperature. It serves as a freewheeling or output rectifier in high-efficiency switching power supplies and reverse battery protection circuits.
For engineers reviewing the VS-MBR1635-M3 datasheet, VS-MBR1635-M3 pinout, VS-MBR1635-M3 application, or VS-MBR1635-M3 equivalent, key selection criteria include thermal resistance (RthJC = 1.50 °C/W), surge capability (IFSM = 1800 A), junction capacitance (CT = 1400 pF), avalanche energy rating (EAS = 24 mJ), and TO-220AC 2L package compatibility with standard heatsink mounting.
Technical Context
This device employs proprietary barrier technology enabling stable operation up to 150 °C junction temperature while maintaining low VF and low IR across temperature. Its guard ring structure enhances ruggedness against mechanical stress and long-term reliability under repetitive surge conditions.
The TO-220AC 2L package features an isolated metal tab (cathode-connected base) and supports DC operation with case temperature limits up to 134 °C at full 16 A rating. Thermal impedance ZthJC is characterized for single-pulse and duty-cycle-dependent transient conditions per JEDEC JESD51 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 16 A - maximum continuous DC or rectangular-wave forward current at TC = 134 °C |
| VRRM / VR | 35 V - maximum DC reverse voltage; defines safe blocking range in battery protection or flyback clamp |
| VF @ 16 A, 125 °C | 0.57 V - low conduction loss enabling >95% efficiency in 12 V output converters |
| IRM @ 125 °C | 40 mA - reverse leakage at max operating temperature; critical for standby power budgeting |
| RthJC | 1.50 °C/W - junction-to-case thermal resistance; determines minimum heatsink requirement for 16 A operation |
| EAS | 24 mJ - unclamped inductive switching energy handling; supports robust freewheeling in motor drives |
| dV/dt | 10,000 V/µs - high voltage transient immunity; prevents false turn-on in fast-switching topologies |
Pinout & Package
Package: TO-220AC 2L - insulated metal tab package with cathode connected to the case (pin 2), anode at pin 1, and no third terminal. Mounting torque: 6–12 kgf·cm (5–10 lbf·in); typical weight: 2 g.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Switch-Mode Power Supply Output Rectification | Reverse Battery Protection |
|---|---|
Use Scenario: Used on the secondary side of isolated DC/DC converters delivering 12–24 V at up to 16 A. IC Role / Device Role / Timing Role: Freewheeling rectifier conducting during low-side switch off-time; handles high-frequency ripple current. Use Value: Low VF (0.57 V) minimizes conduction loss; 1400 pF CT avoids EMI resonance with transformer leakage inductance. | Use Scenario: Placed in series with vehicle battery input to prevent damage during accidental reverse connection. IC Role / Device Role / Timing Role: Unidirectional blocking element; conducts only during correct polarity, blocks reverse voltage up to 35 V. Use Value: Low IR (40 mA @ 125 °C) ensures minimal quiescent drain; 150 °C rating survives under-hood ambient extremes. |
| DC Motor Freewheeling Diode | Industrial DC Link Clamp |
Use Scenario: Mounted across brushed DC motor terminals in 24 V industrial actuators. IC Role / Device Role / Timing Role: Provides path for inductive kickback when PWM drive is interrupted. Use Value: 24 mJ EAS rating absorbs energy from 3.6 A avalanche current; 1800 A IFSM withstands stall-current surges. | Use Scenario: Connected across DC bus capacitors in servo drives to suppress voltage spikes during IGBT turn-off. IC Role / Device Role / Timing Role: Clamping diode limiting bus overvoltage during regenerative braking or load dump events. Use Value: 10,000 V/µs dV/dt rating prevents spurious conduction; RthJC = 1.50 °C/W enables direct heatsink mounting for sustained clamping. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1635CGY | Same 16 A / 35 V rating; VF = 0.59 V @ 16 A, 125 °C; RthJC = 1.6 °C/W; TO-220AC package with cathode tab | Slightly higher VF increases conduction loss by ~35 mW at 16 A; marginally lower thermal performance | Acceptable where 0.02 V VF increase and +0.1 °C/W RthJC are tolerable in thermally constrained layouts |
| ON Semiconductor MBR1635CT | 16 A / 35 V dual common-cathode configuration; VF = 0.61 V @ 16 A, 125 °C; requires 3-pin layout vs. 2-pin VS-MBR1635-M3 | Dual-diode topology unsuitable for single-path applications; larger footprint and extra trace routing needed | Only viable if dual-channel redundancy or interleaved design is required; not a drop-in replacement |
Compared with STPS1635CGY and MBR1635CT, the VS-MBR1635-M3 delivers the lowest VF (0.57 V) and best thermal resistance (1.50 °C/W) in a true 2-pin TO-220AC configuration, making it optimal for space-constrained, high-efficiency 16 A rectification where single-anode/single-cathode topology is mandated.

FAQ
What is the maximum junction temperature rating for VS-MBR1635-M3?
The VS-MBR1635-M3 is rated for a maximum junction temperature (TJ) of +150 °C, validated per JEDEC JESD47 qualification. This allows reliable operation in high-ambient environments such as automotive under-hood systems or sealed industrial enclosures without forced air cooling, provided thermal design respects RthJC = 1.50 °C/W and case temperature limits.
Is VS-MBR1635-M3 pin-compatible with standard TO-220AC rectifiers?
Yes, VS-MBR1635-M3 uses the industry-standard TO-220AC 2L package with anode at pin 1 and cathode-connected metal tab at pin 2. Mounting hole spacing, tab dimensions, and lead pitch match JEDEC TO-220AC specifications, enabling direct mechanical replacement in existing PCB footprints designed for 2-terminal TO-220AC Schottky or fast recovery diodes.
Does VS-MBR1635-M3 support reverse battery protection in automotive 12 V systems?
Yes, VS-MBR1635-M3 is widely used for reverse battery protection in 12 V automotive systems. Its 35 V VR rating exceeds typical load-dump transients, and its 40 mA IR at 125 °C ensures minimal standby current draw. The 150 °C TJ rating accommodates under-hood ambient temperatures up to 85 °C while maintaining safe derating margins for continuous 16 A conduction.
What is the avalanche energy rating (EAS) of VS-MBR1635-M3 and how is it applied?
The VS-MBR1635-M3 has a non-repetitive avalanche energy rating (EAS) of 24 mJ, measured at TJ = 25 °C with IAS = 3.6 A and L = 3.7 mH. This value quantifies its ability to absorb inductive energy during unclamped switching events-such as motor commutation or relay coil de-energization-without failure, supporting robust freewheeling in industrial motion control designs.
How does the -M3 suffix affect the environmental compliance of VS-MBR1635-M3?
The -M3 suffix on VS-MBR1635-M3 indicates halogen-free, RoHS-compliant construction with lead (Pb)-free terminations. It meets JEDEC MSL-1 moisture sensitivity level, requires no baking prior to reflow, and complies with global environmental regulations including EU Directive 2011/65/EU and China RoHS II, making it suitable for consumer, industrial, and automotive production without special handling or exemptions.
