Product details
Overview
MBR2150VG-G1 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-G1 datasheet, MBR2150VG-G1 pinout, MBR2150VG-G1 application, or MBR2150VG-G1 equivalent, key selection criteria include its DO-15 package thermal resistance (80 °C/W), junction temperature range (–65 to +150 °C), surge current rating (75 A), RoHS-compliant green packaging, and guard-ring stress protection for reliability in transient-prone environments.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with integrated guard-ring structure to suppress edge breakdown and improve ruggedness under repetitive surge conditions. Its low forward voltage drop and fast recovery (no minority-carrier storage) minimize conduction and switching losses in high-frequency topologies like flyback and forward converters operating above 100 kHz.
The device is optimized for unidirectional DC output rectification where low noise, minimal EMI generation, and stable performance across –65°C to +150°C junction temperatures are required. It does not support bidirectional conduction or reverse-biased regulation - functioning strictly as a unipolar, anode-to-cathode current path with defined polarity marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 120 VAC-derived 170 VDC bus applications. |
| IF(AV) | 2 A - Average forward current at TC = TBD; defines continuous power-handling capability with appropriate heatsinking. |
| VF (MAX) | 0.85 V @ 2 A, +25°C - Low conduction loss reduces I²R heating and improves efficiency in 5–24 V output rails. |
| IR (MAX) | 0.1 mA @ 150 V, +25°C - Minimal leakage preserves standby power budget in energy-efficient designs. |
| IFSM | 75 A - Non-repetitive surge rating supports cold-start inrush and line-transient events without failure. |
| TJ Range | –65°C to +150°C - Wide junction temperature window enables use in sealed enclosures or high-ambient industrial settings. |
| RθJA | 80 °C/W (DO-15) - Thermal resistance determines required PCB copper area for thermal management at full load. |
Pinout & Package
MBR2150VG-G1 is supplied in the DO-15 axial-leaded package: molded plastic case with matte tin–annealed copper leads, UL 94V-0 flammability rating, and cathode identified 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 withstand peak inverse voltage during off-state. |
| Cathode | Forward current exit point | Connected to output filter capacitor and load; marked by band; carries full output current with minimal voltage drop. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring protected junction | Prevents premature edge breakdown under high dv/dt (10,000 V/µs), enhancing reliability in fast-switching SMPS. |
| Low VF at elevated temperature | 0.67 V @ 2 A, +125°C - maintains efficiency during thermal stress, reducing need for oversized heatsinks. |
| RoHS-compliant green packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb); meets EU Directive 2015/863/EU. |
| ESD robustness | 8000 V HBM - simplifies handling and assembly without special ESD precautions in standard production lines. |
Applications
| AC/DC Adapter Output Rectification | Industrial DC Power Module |
|---|---|
Use Scenario: Rectifying 12–24 VDC outputs from 65–100 W offline flyback converters in wall-wart adapters. IC Role / Device Role / Timing Role: Unidirectional power diode conducting only during positive half-cycle of transformer secondary voltage. Use Value: 0.85 V VF minimizes conduction loss at 2 A load, improving no-load and full-load efficiency to meet DOE Level VI standards. | Use Scenario: Output stage rectification in DIN-rail mounted 48 V/3 A industrial DC power supplies. IC Role / Device Role / Timing Role: Primary output rectifier handling continuous 2 A load with intermittent 75 A surge tolerance during motor startup. Use Value: Guard-ring design ensures stable operation under repeated 150 V transients common in factory floor power distribution. |
| LED Driver Secondary Side | Telecom Power Shelf Rectification |

IC Role / Device Role / Timing Role: Forward-conducting diode delivering regulated DC to LED string; cathode connected to current-sense resistor. Use Value: –65°C to +150°C TJ range allows uninterrupted operation in unheated enclosures exposed to desert or arctic climates. | Use Scenario: 48 V intermediate bus rectification in telecom power shelves supporting hot-swap modules. IC Role / Device Role / Timing Role: High-reliability output rectifier placed after isolation transformer; subject to frequent load insertion/removal. Use Value: 8000 V HBM ESD rating prevents field failures during module servicing and board-level maintenance. |
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 and 2 A IF(AV), but VF = 0.92 V @ 2 A, +25°C; DO-214AC only. | Higher thermal resistance (90 °C/W) requires larger PCB copper area than DO-15 MBR2150VG-G1. | Preferred when surface-mount layout is mandatory; avoid if axial-leaded through-hole mounting is specified. |
| SB2150 (Taiwan Semiconductor) | Identical DO-15 package and marking; VF = 0.87 V @ 2 A, +25°C; IR = 0.15 mA @ +25°C. | Slightly higher leakage may impact ultra-low-power standby modes in battery-backed systems. | Drop-in replacement where green/RoHS compliance is not required; verify leakage sensitivity in final design. |
Compared with SS215 and SB2150, MBR2150VG-G1 offers the lowest forward voltage in DO-15 form factor and guaranteed halogen-free green packaging - making it optimal for space-constrained, thermally sensitive, and environmentally regulated power supply designs.

FAQ
What is the maximum allowable junction temperature for MBR2150VG-G1?
The absolute maximum operating junction temperature is +150°C, with a minimum of –65°C. This range is validated per JEDEC test conditions and supported by thermal resistance data (RθJA = 80 °C/W for DO-15). Derating curves in the datasheet confirm stable operation up to this limit when PCB copper area and airflow meet recommended pad layouts.
Does MBR2150VG-G1 have a built-in guard ring, and what does it do?
Yes - the device integrates a guard-ring structure around the active junction. This feature suppresses electric field crowding at the silicon edge, preventing premature avalanche breakdown under high dv/dt stress (rated 10,000 V/µs) and improving ruggedness during line surges or transformer ringing in SMPS circuits.
Can MBR2150VG-G1 be used in place of a standard PN junction rectifier?
Yes, but only where low forward voltage and fast recovery are advantageous. Unlike PN diodes, it has no reverse recovery charge (Qrr ≈ 0), eliminating switching spikes and EMI. However, its higher reverse leakage at elevated temperature means it is unsuitable for high-impedance hold-up or precision reference applications where leakage must remain below 10 nA.
Is the DO-15 package of MBR2150VG-G1 compatible with automated through-hole insertion equipment?
Yes - the DO-15 package features standardized axial leads with 0.035 inch diameter and 25.4 mm (1.0 inch) minimum lead spacing, conforming to IPC-7351 and JEDEC TO-204AA specifications. Lead finish is matte tin annealed over copper, ensuring reliable solder wetting in wave and selective soldering processes.
