Product details
Overview
MBR10150CT from Diodes Incorporated is a dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 150 V reverse voltage and 5 A average forward current per leg (10 A total), with max 0.89 V forward voltage at 5 A and 25°C, used as polarity protection and freewheeling diode in DC/DC converters and industrial power supplies.
For engineers reviewing the MBR10150CT datasheet, MBR10150CT pinout, MBR10150CT application, or MBR10150CT equivalent, key selection criteria include low VF for efficiency, 100 A non-repetitive surge rating for transient robustness, AEC-Q101 qualification for automotive-grade reliability, and TO-220AB thermal resistance of 4°C/W junction-to-case.
Technical Context
This dual-leg Schottky rectifier integrates two independent anode terminals sharing one cathode terminal, enabling synchronous half-wave rectification or independent polarity protection paths. Its guard ring die construction suppresses edge leakage and improves high-temperature IR stability up to 175°C junction temperature.
Designed for commercial and automotive applications, it delivers low conduction loss with VF ≤ 0.89 V @ 5 A / 25°C and IR ≤ 0.05 mA @ 150 V / 25°C, while supporting 100 A IFSM surge capability under 8.3 ms half-sine waveform - critical for inductive load switching and motor drive flyback protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - blocks up to 150 V reverse bias without breakdown, suitable for 12–48 V system bus protection |
| IO (per leg) | 5 A - continuous DC current handling per anode path, supports 10 A total dual-leg output |
| VF (max) | 0.89 V @ 5 A, 25°C - enables <0.45 W conduction loss per leg, reducing heatsink requirements |
| IFSM | 100 A - withstands short-duration inductive kickback surges common in relay/motor control |
| RθJC | 4°C/W - allows efficient heat transfer to heatsink, enabling >4 W dissipation at ΔT = 16°C |
| IR (max) | 0.05 mA @ 150 V, 25°C - ensures minimal standby leakage in battery-backed or always-on systems |
| TJ range | −55°C to +175°C - qualified for under-hood automotive and industrial ambient environments |

Applications
| DC/DC Converter Output Rectification | Automotive Engine Control Unit (ECU) Polarity Protection |
|---|---|
Use Scenario: Used on secondary side of isolated flyback or forward converter delivering 5–12 V @ 5–8 A to microcontroller and sensor rails. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier providing low-loss, high-efficiency DC output with shared cathode return path. Use Value: 0.89 V VF reduces conduction loss by ~35% vs. standard PN diode, lowering thermal load on PCB and enabling smaller heatsinks. | Use Scenario: Installed between vehicle battery input and ECU main power rail to prevent damage from reverse battery connection. IC Role / Device Role / Timing Role: Polarity protection diode with common-cathode configuration enabling dual-battery or redundant input support. Use Value: 100 A IFSM withstands jump-start transients; −55°C to +175°C rating ensures operation across cold cranking to under-hood thermal extremes. |
| Industrial Motor Drive Freewheeling | Telecom Power Shelf Input Protection |
Use Scenario: Placed across brushed DC motor windings or relay coils to clamp inductive kickback during PWM switching. IC Role / Device Role / Timing Role: Re-circulating diode providing low-VF path for stored inductive energy recovery. Use Value: Fast recovery (inherent to Schottky) and 4°C/W RθJC enable reliable clamping at 10 kHz PWM frequencies without thermal runaway. | Use Scenario: Positioned at front-end of 48 V telecom shelf to block reverse current from backup batteries or hot-swap modules. IC Role / Device Role / Timing Role: Reverse-current blocking diode with dual-anode layout allowing parallel input sources. Use Value: 0.05 mA IR at 150 V minimizes standby drain in always-on telecom systems; TO-220AB facilitates manual rework and high-current trace routing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR10150CT | Identical 150 V / 5 A per leg rating; VF = 0.87 V max @ 5 A / 25°C; same TO-220AB package and pinout | No functional difference; validated in identical automotive and industrial designs | Select for multi-source procurement where Vishay supply chain preference applies |
| ON Semiconductor MBR10150CTG | Same electrical specs; RoHS-compliant but not AEC-Q101 qualified; RθJC = 4.5°C/W (slightly higher thermal resistance) | Suitable for commercial-only applications; not recommended for automotive under-hood use | Choose when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
Compared with VS-MBR10150CT, MBR10150CT offers identical performance and drop-in compatibility; versus MBR10150CTG, it adds AEC-Q101 qualification and marginally better thermal resistance - critical for automotive and high-reliability industrial deployments.

FAQ
Is MBR10150CT suitable for surface-mount assembly?
No. MBR10150CT uses a TO-220AB through-hole package with a metal tab designed for mechanical mounting and heatsinking via screw or clip. It lacks SMD-compatible footprint or thermal pad layout, and its 1.95 g mass exceeds typical reflow handling limits for automated SMT lines.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +175°C, but continuous operation should be limited to ≤150°C to ensure long-term reliability. Derating curves show 5 A IO per leg is sustainable only up to ~100°C ambient when mounted on a 45 mm × 20 mm heatsink, per datasheet Figure 4.
Does the common cathode pin connect to the metal tab?
Yes. Pin 2 (cathode) is internally bonded to the exposed metal tab, which serves as both the electrical cathode node and primary thermal path. The tab must be electrically isolated from chassis ground unless circuit topology requires cathode grounding.
Can MBR10150CT replace a single 10 A Schottky diode?
No - it is a dual 5 A device with separate anodes and shared cathode. To replace a single 10 A diode, both anodes must be paralleled externally, but this introduces imbalance risk due to VF mismatch. For true 10 A single-path use, select a monolithic 10 A Schottky like MBR20150CT.
