Product details
Overview
MBR5H150VPA-G1 from Diodes Incorporated is a high-voltage Schottky rectifier optimized for switch-mode power supply output stages, featuring 150 V peak reverse voltage, 5 A average forward current, 0.92 V max forward voltage at +25°C, 8 µA max reverse leakage at +25°C, and +175°C junction temperature rating. It delivers low switching losses and low noise in high-frequency DC-DC converters and AC-DC adapters.
For engineers reviewing the MBR5H150VPA-G1 datasheet, MBR5H150VPA-G1 pinout, MBR5H150VPA-G1 application, or MBR5H150VPA-G1 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (RθJC = 10°C/W), surge current capability (125 A), guard-ring protection, and DO-27 package compatibility with standard through-hole PCB layouts.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with integrated guard-ring structure to suppress edge breakdown and improve voltage stability under transient stress. Its low VF and ultra-low IR stem from optimized metal-semiconductor interface design and tight process control across the Si die.
The device operates reliably up to +175°C junction temperature and supports dv/dt rates up to 10,000 V/µs-enabling robust performance in fast-switching topologies like active-clamp flyback and synchronous rectification circuits where reverse recovery noise must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Withstands repetitive reverse voltage up to 150 V without breakdown; suitable for 48 V–110 V input SMPS designs. |
| IF(AV) | 5 A - Sustains continuous 5 A DC output current at TC = +150°C; enables compact heatsink sizing in medium-power supplies. |
| VF (max) | 0.92 V @ 5 A, +25°C - Minimizes conduction loss; reduces I²R heating by ~30% vs. comparable 1.2 V Si diodes at same current. |
| IR (max) | 8 µA @ 150 V, +25°C - Ensures negligible standby leakage in energy-sensitive applications like IoT power rails. |
| IFS M | 125 A - Handles single half-sine surge without failure; supports inrush current in offline AC-DC front-ends. |
| TJ (max) | +175°C - Enables operation in thermally constrained environments such as enclosed industrial power modules. |
| RθJC | 10°C/W - Allows direct thermal path to heatsink; simplifies thermal design when mounted on copper pour or metal-core PCB. |
Pinout & Package
MBR5H150VPA-G1 is housed in the DO-27 axial-leaded package (JEDEC TO-204-AC), with cathode identified by a band marking. The package features matte tin-annealed copper leads, UL 94V-0 molded plastic body, and 1.2 g mass. It complies with RoHS and Diodes Inc.'s "Green" specification (halogen/antimony-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connected to transformer secondary or switching node; carries full load current during on-state. |
| Cathode | Output terminal for forward conduction | Connected to output capacitor and load; polarity-marked with band; defines output voltage reference point. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring protected junction | Prevents premature edge breakdown under high dv/dt or localized thermal stress; improves long-term reliability in noisy SMPS environments. |
| +175°C maximum junction temperature | Enables uninterrupted operation in sealed enclosures or high-ambient industrial settings without derating at full current. |
| Low 0.92 V forward drop at 5 A | Reduces power dissipation by ≥1.5 W versus 1.2 V alternatives-critical for efficiency-critical 5–20 W adapters. |
| DO-27 mechanical compatibility | Direct replacement for legacy 1N5822/1N5823 in existing through-hole footprints; no layout change required. |

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 |
|---|---|---|---|
| STPS5H100CG | 100 V VRRM, same 5 A IF(AV), VF = 0.87 V @ 5 A, DO-27 package | Lower voltage rating limits use to ≤48 V systems; unsuitable for 110 V AC-derived rails. | Select only when system max reverse voltage ≤100 V and lower VF is prioritized over voltage margin. |
| ON Semiconductor MBR5H150FCT | Same 150 V/5 A specs, but in SMC (DO-214AB) surface-mount package | Requires PCB redesign; not drop-in compatible with through-hole DO-27 footprint. | Choose for automated assembly or space-constrained designs where reflow compatibility outweighs legacy footprint retention. |
Compared with STPS5H100CG and MBR5H150FCT, MBR5H150VPA-G1 uniquely balances 150 V ruggedness, DO-27 through-hole compatibility, and sub-0.95 V forward drop-making it optimal for cost-sensitive, medium-power SMPS upgrades requiring zero layout change.

FAQ
What is the maximum allowable case temperature for continuous operation?
The MBR5H150VPA-G1 supports continuous operation up to +150°C case temperature while delivering its full 5 A average forward current rating. Derating begins above this point per Figure 4 in the datasheet, with 0 A current allowed at +175°C ambient only under zero-power conditions. Thermal design must ensure RθJC × PD does not exceed TJ − TC.
Is the DO-27 (C) variant pin-compatible with standard DO-27?
Yes-both DO-27 and DO-27 (C) share identical anode/cathode terminal assignments and axial lead configuration. The (C) suffix denotes a modified body contour for improved mechanical stability during wave soldering, but electrical behavior, pinout, and PCB footprint remain fully interchangeable.
Does this part meet IPC/JEDEC J-STD-020 moisture sensitivity requirements?
Yes-the MBR5H150VPA-G1 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. No floor life limitation applies, and it is compatible with standard reflow or wave soldering profiles.
Can this Schottky rectifier replace a standard silicon PN diode in an existing design?
Yes, provided the circuit's peak reverse voltage does not exceed 150 V and the forward current remains within 5 A average. Due to near-zero reverse recovery time, it eliminates switching losses and EMI associated with PN diodes-but requires verification of thermal margin, as VF is lower but leakage rises faster with temperature.
