Product details
Overview
MBR5H150VPB-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 - deployed in DC-DC converters and AC-DC secondary-side rectification.
For engineers reviewing the MBR5H150VPB-G1 datasheet, MBR5H150VPB-G1 pinout, MBR5H150VPB-G1 application, or MBR5H150VPB-G1 equivalent, key selection criteria include low VF for efficiency-critical 100–500 kHz SMPS designs, high dv/dt capability (10,000 V/µs), surge robustness (125 A IFSM), thermal resilience (+175°C TJ), and DO-27 package compatibility with legacy board layouts.
Technical Context
This Schottky rectifier uses a planar epitaxial structure with guard-ring protection to suppress edge breakdown under high-voltage stress, enabling stable operation up to 150 V VRRM while maintaining low conduction loss. Its low Qrr and absence of minority-carrier storage minimize switching losses and EMI generation in high-frequency power conversion.
The device operates with a maximum junction temperature of +175°C and exhibits a thermal resistance of 10°C/W (Junction-to-Case) when mounted on a heatsink, supporting compact thermal design in space-constrained power supplies. Reverse leakage remains tightly controlled at ≤8 µA @ 25°C and ≤50 mA @ 150°C, ensuring reliability across wide ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Withstands repetitive reverse voltage up to 150 V without breakdown in SMPS flyback or forward converter secondary circuits. |
| IF(AV) | 5 A - Sustains continuous 5 A DC output current at TC = +150°C, suitable for 60–100 W adapter and server PSU designs. |
| VF (max) | 0.92 V @ 5 A, +25°C - Reduces conduction loss by ~30% vs. comparable fast recovery diodes, improving full-load efficiency by 0.5–1.2%. |
| IR (max) | 8 µA @ 150 V, +25°C - Enables low standby power in energy-efficient adapters meeting Level VI and CoC Tier 2 requirements. |
| IFSM | 125 A - Survives cold-start surges and transient overloads without degradation in industrial and computing power rails. |
| TJ(max) | +175°C - Allows operation in thermally demanding environments (e.g., enclosed LED drivers, PoE injectors) without derating penalties. |
| dv/dt | 10,000 V/µs - Resists false triggering during fast voltage transients in high-speed synchronous rectifier control schemes. |
Pinout & Package
MBR5H150VPB-G1 is housed in the DO-27 axial-leaded plastic package (JEDEC TO-204-AC), with cathode identified by a band marking on the body. The package meets UL 94V-0 flammability rating and supports manual or wave soldering per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to transformer secondary or switching node; must handle 5 A continuous and 125 A surge without bond wire fusing. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output capacitor ground or common return; critical for minimizing loop inductance in high-dI/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring protected junction | Prevents premature edge breakdown at 150 V, enabling stable long-term operation under voltage stress and thermal cycling. |
| +175°C maximum junction temperature | Permits full 5 A current delivery at elevated case temperatures, reducing need for oversized heatsinks in sealed enclosures. |
| Low 0.92 V forward drop | Directly lowers I²R losses in high-current output paths, cutting thermal load by ~1.8 W vs. 1.1 V Si diode at 5 A. |
| Pb-free, halogen-free "Green" construction | Complies with RoHS 2 and JEDEC J-STD-020 moisture sensitivity Level 1, eliminating reflow concerns and enabling global market access. |
| 10,000 V/µs voltage slew rate rating | Ensures immunity to parasitic ringing in high-frequency LLC and resonant converters, preventing unintended conduction or failure. |
Applications
| Server Power Supply Rectification | Industrial DC-DC Converter Output |
|---|---|
Use Scenario: Secondary-side rectification in 1U server PSUs delivering 50–100 W at 12 V/5 V outputs. IC Role / Device Role / Timing Role: Primary unidirectional power path component converting high-frequency transformer output to regulated DC. Use Value: 0.92 V VF reduces conduction loss by 1.1 W per diode vs. standard FRD, lowering thermal density and enabling fanless operation. | Use Scenario: Output stage in isolated 24 V input, 5 V/3 A industrial DC-DC modules operating in -40°C to +85°C ambient. IC Role / Device Role / Timing Role: High-reliability rectifier handling repetitive 125 A surge events during motor startup or capacitive load switching. Use Value: +175°C TJ rating allows full 5 A current at 85°C ambient without derating, eliminating need for parallel devices. |
| LED Driver Secondary Rectification | Telecom PoE Injector Output |
Use Scenario: Constant-current LED driver with flyback topology powering streetlight arrays (36–72 V output). IC Role / Device Role / Timing Role: High-efficiency rectifier in discontinuous conduction mode (DCM) operation at 65–130 kHz switching frequency. Use Value: Low Qrr and absence of reverse recovery charge suppress EMI, easing compliance with CISPR-15 Class B limits. | Use Scenario: 48 V to 57 V PoE++ (IEEE 802.3bt Type 4) injector output rectification feeding powered devices. IC Role / Device Role / Timing Role: High-voltage, low-loss rectifier sustaining 5 A continuous current under sustained 57 V reverse bias and thermal stress. Use Value: 150 V VRRM provides 20% margin above 57 V PoE+ max, ensuring robustness against line transients and ringback voltages. |
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 |
|---|---|---|---|
| Vishay VS-MBR5150TRPBF | Same 150 V/5 A rating; VF = 0.95 V @ 5 A; RθJA = 45°C/W (vs. 40°C/W); DO-201AD package. | DO-201AD has larger footprint and higher thermal resistance - requires PCB copper area adjustment for equivalent thermal performance. | Select if DO-201AD is already standardized in production; verify thermal pad layout matches higher RθJA. |
| ON Semiconductor MBR5H150T3G | Identical electrical specs; same DO-27 package; VF = 0.92 V @ 5 A; but rated for +150°C TJ (vs. +175°C). | Limited high-temp headroom in sealed enclosures above 125°C ambient; may require derating in high-power density designs. | Acceptable for commercial-grade applications below +125°C case temperature; avoid in extended-temperature industrial deployments. |
Compared with VS-MBR5150TRPBF and MBR5H150T3G, MBR5H150VPB-G1 offers superior thermal capability (+175°C TJ), lower thermal resistance (10°C/W J-C), and DO-27 mechanical compatibility - making it optimal for high-density, high-reliability power supplies where thermal margin and legacy footprint retention are critical.

FAQ
What is the cathode identification method for MBR5H150VPB-G1?
The cathode is marked by a distinct color band on the DO-27 package body, located near one lead end. This band aligns with the cathode terminal shown in the top-view pin diagram in DS36967 Rev. 4–2, page 2. The anode lead is unmarked and extends from the opposite end.
Can MBR5H150VPB-G1 be used in synchronous rectification circuits?
No - MBR5H150VPB-G1 is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It lacks gate terminals or control logic. It functions only as a two-terminal unidirectional conductor and must be paired with external timing circuitry if used in quasi-synchronous configurations.
Is the DO-27 (C) variant electrically identical to the standard DO-27 version?
Yes - MBR5H150VPB-G1 uses the standard DO-27 package (not DO-27(C)). The DO-27(C) variant (e.g., MBR5H150VPC-G1) shares identical electrical specifications, thermal ratings, and pinout, differing only in leadform geometry (90° bent leads) for specific board-mounting requirements.
What is the maximum allowable soldering temperature profile for MBR5H150VPB-G1?
The device complies with JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard Pb-free reflow profiles: peak temperature ≤260°C, time above 217°C ≤60 seconds, ramp-up rate ≤3°C/s. Wave soldering is also qualified per MIL-STD-202, Method 208, using matte tin annealed leads.
