Product details
Overview
MBR2150VG-E1 from Diodes Incorporated is a high-voltage Schottky rectifier designed for output rectification in switch-mode power supplies and medium-voltage, high-frequency DC-DC converters. It delivers 2 A average forward current at 150 V peak reverse voltage, with 0.85 V max forward voltage at +25°C and 0.1 mA max reverse leakage at rated voltage - enabling low-loss, low-noise operation in compact AC/DC adapters and industrial power modules.
For engineers reviewing the MBR2150VG-E1 datasheet, MBR2150VG-E1 pinout, MBR2150VG-E1 application, or MBR2150VG-E1 equivalent, key selection criteria include its DO-15 package thermal resistance (80 °C/W), surge rating (75 A), junction temperature range (–65°C to +150°C), RoHS-compliant lead-free finish, and guard-ring stress protection for reliability in repetitive switching environments.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with integrated guard-ring structure to suppress edge breakdown under high dv/dt (10,000 V/µs) and improve ruggedness against transient overvoltage. Its low forward voltage drop stems from optimized metal-semiconductor interface design, not PN-junction conduction.
Unlike conventional PN diodes, it exhibits no minority-carrier storage delay, eliminating reverse recovery charge (Qrr ≈ 0) - critical for reducing switching losses and EMI in 100 kHz–1 MHz SMPS topologies where fast turn-off and minimal ringing are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines safe operating ceiling in flyback or LLC resonant converter secondary-side rectification. |
| IF(AV) | 2 A - Average forward current rating at specified thermal conditions; determines continuous power-handling capability in 24 V/48 V telecom or industrial PSU outputs. |
| VF (MAX) | 0.85 V @ 2 A, +25°C - Low conduction loss enables >92% efficiency in 12 V output rails with minimal heatsinking. |
| IR (MAX) | 0.1 mA @ 150 V, +25°C - Ultra-low leakage preserves hold-up time and reduces standby power in energy-efficient designs. |
| IFS M | 75 A - Non-repetitive surge current capacity supports inrush tolerance during cold-start or line transients without latch-up. |
| TJ Range | –65°C to +150°C - Wide junction temperature window allows deployment in unventilated enclosures or high-ambient industrial environments. |
Pinout & Package
MBR2150VG-E1 is supplied in the DO-15 axial-leaded package: molded plastic case (UL 94V-0), matte tin–annealed copper leads, 0.39 g mass, and cathode-indicated by a band marking on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to transformer secondary or switching node; must handle full load current and surge peaks without voltage derating. |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; ties to output capacitor positive rail; requires clean layout to minimize parasitic inductance in high-dI/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring protected junction | Prevents premature edge breakdown under high electric field stress, extending lifetime in high-voltage ripple applications. |
| RoHS-compliant & halogen-free "Green" packaging | Meets EU RoHS 3 (2015/863/EU) and Diodes' <900 ppm Br/Cl, <1000 ppm Sb specification for eco-sensitive manufacturing. |
| Low thermal resistance (RθJA = 80 °C/W) | Enables 2 A operation at +70°C ambient without forced airflow when mounted per recommended pad layout. |
| ESD robustness (HBM 8 kV, MM 400 V) | Reduces handling damage risk during manual assembly or rework in low-volume production lines. |
Applications
| AC/DC Adapter Output Rectification | Industrial DC-DC Converter Secondary Side |
|---|---|
Use Scenario: 12 V/2 A output stage of universal-input offline adapter powering IoT gateways. IC Role / Device Role / Timing Role: Primary unidirectional power path from transformer secondary to bulk capacitor; conducts only during positive half-cycle. Use Value: 0.85 V VF minimizes conduction loss (1.7 W vs. ~2.4 W for Si diode), directly improving no-load efficiency and thermal margin. | Use Scenario: 24 V isolated output in DIN-rail mounted PLC power module. IC Role / Device Role / Timing Role: High-frequency synchronous rectifier replacement in forward converter topology operating at 250 kHz. Use Value: Zero Qrr eliminates reverse recovery spikes, reducing EMI filter size and enabling smaller output capacitors. |
| Telecom Power Shelf Rectification | LED Driver Constant-Current Stage |
Use Scenario: +48 V intermediate bus rectification in multi-output telecom shelf with 100 ms hold-up requirement. IC Role / Device Role / Timing Role: Main DC feed diode feeding downstream buck regulators; subjected to repeated 75 A surge events during hot-swap insertion. Use Value: 75 A IFSM rating ensures survival across 10⁵+ hot-plug cycles without degradation. | Use Scenario: Constant-current sink rectification in 36 V LED string driver for street lighting. IC Role / Device Role / Timing Role: Reverse-polarity protection and output rectifier in buck-boost LED controller feedback loop. Use Value: 0.1 mA IR at +125°C prevents thermal runaway in enclosed outdoor housings, maintaining stable current regulation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS215 (ON Semiconductor) | Same 150 V VRRM, 2 A IF(AV), but VF = 0.9 V @ 2 A (+25°C); RθJA = 85 °C/W; DO-214AA package. | Larger footprint and slightly higher conduction loss; less suitable for space-constrained adapters. | Select if DO-214AA board layout already exists and minor efficiency trade-off is acceptable. |
| SB2150 (Vishay) | Identical 150 V/2 A rating, VF = 0.82 V @ 2 A (+25°C), but IR = 0.25 mA @ +25°C; DO-15 package with same pinout. | Higher leakage may impact standby power in Energy Star–certified designs requiring <30 mW no-load consumption. | Prefer for ultra-low VF-critical designs where leakage is managed via auxiliary circuitry. |
Compared with SS215 and SB2150, MBR2150VG-E1 offers the best balance of low VF (0.85 V), ultra-low IR (0.1 mA), and DO-15 compatibility - making it optimal for thermally constrained, low-standby-power AC/DC systems requiring long-term reliability.

FAQ
What is the maximum junction temperature and how does it affect PCB layout?
The MBR2150VG-E1 has a rated operating junction temperature range of –65°C to +150°C. To sustain 2 A continuous current near the upper limit, the PCB must provide adequate copper area per the recommended DO-15 pad layout (minimum 5.6 mm × 2.1 mm thermal pad), and avoid enclosing the device in sealed cavities without airflow. Exceeding +150°C risks irreversible parametric shift and accelerated degradation.
Is MBR2150VG-E1 suitable for synchronous rectification circuits?
No - MBR2150VG-E1 is a passive Schottky rectifier, not a controlled MOSFET-based synchronous rectifier. It lacks gate drive terminals and cannot be actively switched. It functions as a freewheeling or output rectifier in non-synchronous topologies like flyback, forward, or boost converters where simplicity and cost outweigh marginal efficiency gains from active control.
How does the guard-ring structure improve reliability in high-voltage operation?
The integrated guard-ring redistributes electric field intensity away from the semiconductor edge, preventing localized avalanche breakdown under high dv/dt or reverse-biased transients. This extends operational life in applications with voltage spikes (e.g., transformer leakage inductance ringing), especially when used without snubbers in cost-sensitive power supplies.
Can MBR2150VG-E1 replace a standard silicon rectifier like 1N4007 in existing designs?
Yes, as a direct functional upgrade - but only if the circuit operates below 150 V reverse voltage and benefits from lower VF. Unlike the 1N4007 (1 A, 1000 V, 1.1 V VF), MBR2150VG-E1 offers higher current (2 A), lower VF (0.85 V), and zero Qrr, but lower VRRM. It must not be used in 230 VAC input bridge legs or other >150 V reverse-bias locations without redesign.
