Product details
Overview
MBR5H150VPB-E1 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 5 A and 8.0 µA max reverse leakage at +25°C. It operates up to +175°C junction temperature and is packaged in DO-27 (C) with matte tin–annealed copper leads.
For engineers reviewing the MBR5H150VPB-E1 datasheet, MBR5H150VPB-E1 pinout, MBR5H150VPB-E1 application, or MBR5H150VPB-E1 equivalent, key selection criteria include low forward voltage for efficiency-critical DC/DC outputs, high surge rating (125 A IFSM), thermal robustness (RθJC = 10°C/W), and RoHS-compliant "Green" packaging with UL 94V-0 flammability rating.
Technical Context
This Schottky rectifier uses a guard-ring–protected silicon die structure to suppress edge breakdown under high dv/dt stress (10,000 V/µs), enabling stable operation in high-frequency SMPS topologies. Its low Qrr and absence of minority-carrier storage minimize switching losses and EMI generation during hard commutation.
The device is rated for continuous conduction at TC = +150°C with IF(AV) = 5 A, supported by a maximum junction temperature of +175°C and thermal resistance of 10°C/W (junction-to-case) when mounted on an appropriate heatsink per Diodes' recommended pad layout.
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 and 110 V AC-input derived DC bus applications. |
| IF(AV) | 5 A - Sustains 5 A average forward current at TC = +150°C; defines continuous output rectification capability in high-power adapters. |
| VF (max) | 0.92 V @ 5 A, +25°C - Low conduction loss reduces heat generation and improves system efficiency in high-current paths. |
| IR (max) | 8.0 µA @ 150 V, +25°C - Ultra-low leakage preserves standby power integrity and prevents unintended discharge in hold-up capacitors. |
| IFS M | 125 A - Handles short-duration line surges and inrush currents without failure; critical for input-stage transient resilience. |
| TJ (max) | +175°C - Enables reliable operation in thermally constrained enclosures or high-ambient industrial environments. |
| RθJC | 10°C/W - Confirms efficient heat transfer to heatsink; supports compact thermal design with minimal derating at elevated case temperatures. |
Pinout & Package
MBR5H150VPB-E1 is supplied in the DO-27 (C) axial-leaded package: cylindrical body with cathode band marking, 8.5–9.5 mm length, 5.0–5.6 mm diameter, and 1.2–1.3 mm lead diameter. Leads are matte tin–annealed over copper, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |

| RoHS-compliant "Green" packaging | Contains <900 ppm Br, <900 ppm Cl, <1000 ppm Sb; satisfies global environmental compliance mandates without performance trade-offs. |
Applications
| Server Power Supply Rectification | Industrial DC/DC Converter Output |
|---|---|
Use Scenario: High-efficiency 12 V/48 V output stage in 80 PLUS Titanium server PSUs handling >1 kW loads. IC Role / Device Role / Timing Role: Primary output rectifier replacing fast recovery diodes to reduce conduction loss and thermal stress. Use Value: 0.92 V VF lowers power dissipation by ~1.2 W vs. 1.1 V Si diode at 5 A, reducing heatsink size and improving MTBF. | Use Scenario: Isolated 24 V output in programmable logic controller (PLC) power modules operating continuously at +70°C ambient. IC Role / Device Role / Timing Role: Secondary-side freewheeling rectifier in forward or flyback topology. Use Value: +175°C TJ rating ensures margin against thermal runaway during sustained overload or poor airflow conditions. |
| LED Driver Hold-up Circuit | Telecom AC/DC Adapter Output |
Use Scenario: Output rectification in constant-current LED drivers powering streetlights with 300 ms hold-up time requirement. IC Role / Device Role / Timing Role: Main DC path rectifier feeding bulk capacitor bank; must sustain 5 A average current with low IR. Use Value: 8.0 µA IR at +25°C minimizes capacitor self-discharge, preserving hold-up duration across temperature extremes. | Use Scenario: 48 V output rectification in telecom-grade AC/DC adapters used in remote radio units (RRUs). IC Role / Device Role / Timing Role: High-reliability output diode subjected to repeated lightning-induced surges. Use Value: 125 A IFSM rating provides margin against 10/1000 µs surge events per IEC 61000-4-5 Level 4. |
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-MBR5H150-M3/45 | Same 150 V/5 A rating; VF = 0.93 V @ 5 A; RθJC = 11°C/W; DO-201AD package (larger footprint, higher thermal mass). | DO-201AD requires larger PCB pad area and has slower thermal response than DO-27 (C); less suitable for space-constrained designs. | Select when board layout allows larger package and higher surge immunity is prioritized over footprint density. |
| ON Semiconductor MBR5H150T3G | Identical electrical specs; VF = 0.92 V @ 5 A; same DO-27 (C) package; but rated only to +150°C TJ (not +175°C). | Limited to lower ambient or forced-air-cooled applications; not qualified for sealed +70°C industrial enclosures. | Choose only if thermal budget permits ≤+150°C junction operation and legacy BOM compatibility is required. |
Compared with VS-MBR5H150-M3/45 and MBR5H150T3G, MBR5H150VPB-E1 uniquely combines DO-27 (C) compactness, +175°C junction rating, and 10°C/W thermal resistance-enabling smaller heatsinks and higher reliability in thermally aggressive deployments.

FAQ
What is the maximum allowable case temperature for continuous operation?
The MBR5H150VPB-E1 supports continuous operation at TC = +150°C with IF(AV) = 5 A, as specified in the Absolute Maximum Ratings table. Operation above this temperature requires derating per Figure 3 (IF(AV) vs. TC), and junction temperature must remain ≤+175°C under all conditions.
Is the DO-27 (C) package compatible with standard axial-leaded automated assembly?
Yes - the DO-27 (C) package features straight, tinned copper leads with 1.2–1.3 mm diameter and 19.5–20.5 mm length, meeting IPC-J-STD-020 Level 1 moisture sensitivity and MIL-STD-202 solderability requirements for wave and reflow processes.
Does the "Green" designation affect electrical performance?
No - the "Green" status refers solely to halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) and does not alter VF, IR, or thermal characteristics. Electrical specs match non-Green variants; only material composition differs per environmental compliance requirements.
Can MBR5H150VPB-E1 replace a standard PN-junction rectifier in an existing design?
Yes, provided reverse voltage and surge requirements are met - but note its lower VF reduces conduction loss and heat generation, potentially allowing heatsink downsizing. Verify layout clearance for DO-27 (C) dimensions and confirm no parasitic oscillation due to faster switching (no reverse recovery tail).
