Product details
Overview
MBR20150CT-E1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220-3 package, rated for 150 V reverse voltage, 10 A per diode leg (20 A total), and 0.9 V max forward voltage at 10 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR20150CT-E1 datasheet, MBR20150CT-E1 pinout, MBR20150CT-E1 application, or MBR20150CT-E1 equivalent, key selection criteria include thermal resistance (RθJC = 2.0°C/W), junction temperature limit (+150°C), surge current capability, RoHS-compliant lead-free finish, and dual-leg parallel conduction architecture.
Technical Context
This dual Schottky rectifier integrates two independent 150 V / 10 A diode elements sharing a common cathode terminal, enabling synchronous or interleaved output rectification in center-tapped or dual-output DC/DC converters. Its guard-ring structure enhances ruggedness against transient overvoltage stress.
Designed for medium-voltage, high-frequency operation, it avoids minority-carrier storage delay and exhibits negligible reverse recovery charge (Qrr ≈ 0), eliminating snubber circuits in 100–500 kHz switch-mode power supplies. The TO-220-3 mechanical form supports direct heatsink mounting with low thermal resistance path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per diode leg; defines safe operating range in flyback or forward converter secondary side. |
| IF(AV) per leg | 10 A - Average forward current rating per diode at TC = +134°C; enables 20 A combined output with shared cathode layout. |
| VF (max) | 0.9 V @ 10 A, +25°C - Low conduction loss reduces heat generation and improves efficiency in high-current 12–48 V output rails. |
| IR (max) | 0.05 mA @ 150 V, +25°C - Ultra-low leakage preserves regulation in standby mode and minimizes no-load power loss. |
| TJ (max) | +150°C - High junction temperature rating allows operation in compact, thermally constrained enclosures without derating. |
| RθJC | 2.0°C/W - Thermal resistance from junction to case enables effective heatsinking with minimal thermal interface material. |
| ESD HBM | >8000 V - Robust human-body-model ESD tolerance simplifies handling and board-level assembly without special precautions. |
Pinout & Package
Package: TO-220-3 (2), molded plastic case with matte tin–annealed copper leadframe, UL 94V-0 rated, RoHS-compliant, "Green" (halogen/antimony-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode Leg 1 | Independent anode connection for first Schottky diode element; used in dual-output or phase-split rectification. |
| 2 (K) | Common Cathode | Shared cathode node for both diodes; serves as output return path in center-tapped transformer configurations. |
| 3 (A2) | Anode Leg 2 | Independent anode connection for second Schottky diode element; enables symmetrical current sharing in parallel rectifier designs. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.9 V max @ 10 A ensures ≤9 W conduction loss per leg at full load, critical for 80 PLUS Titanium PSUs. |
| Guard-ring protected junction | Enhances avalanche ruggedness and long-term reliability under repetitive line transients in industrial AC/DC adapters. |
| +150°C junction rating | Supports continuous operation in sealed enclosures up to ambient +85°C with standard heatsinking. |
| RoHS + Green compliance | Pb-free, halogen-free, antimony-free construction meets IEC 61249-2-21 and JEDEC JS709C requirements. |
| High surge current capacity | IFS(M) rated ≥120 A (typical, per datasheet curves) handles cold-start inrush without degradation. |
Applications
| Server Power Supply Rectification | Industrial DC/DC Converter Output |
|---|---|
Use Scenario: Primary 12 V / 54 A output stage in 1U rack-mount server PSU using center-tapped transformer topology. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier providing synchronous rectification with common-cathode return to minimize PCB trace inductance. Use Value: Reduces conduction loss by 35% vs. fast recovery diode, lowering thermal design margin and enabling fanless operation. | Use Scenario: 24 V output rectification in DIN-rail mounted programmable logic controller (PLC) power module. IC Role / Device Role / Timing Role: Medium-voltage output rectifier handling 10 A continuous load with transient surges up to 60 A. Use Value: Guard-ring protection prevents failure during motor drive-induced line transients; +150°C rating sustains operation in unventilated control cabinets. |
| Telecom Rectifier Module | Medical Imaging Power Subsystem |

IC Role / Device Role / Timing Role: Low-leakage rectifier maintaining stable bias voltage during standby intervals between image acquisitions. Use Value: IR ≤ 0.05 mA at +25°C and ≤ 20 mA at +125°C prevents drift in precision analog front-end references. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR20150CT-G1 | Same electrical specs; green (halogen/antimony-free) package variant with identical TO-220-3 outline and marking. | No functional difference; selected when full "Green" compliance (Br+Cl <1500 ppm) is mandated by OEM sustainability policy. | Choose G1 for eco-design programs; E1 remains valid where RoHS-only compliance suffices. |
| MBR20150CTF-E1 | Same die, but in TO-220F-3 (full-pack) package with insulated backside; RθJC = 3.0°C/W vs. 2.0°C/W for TO-220-3. | Used where electrical isolation from heatsink is required (e.g., floating outputs); trades 33% higher thermal resistance for safety compliance. | Select TO-220F-3 only when isolation >500 V RMS is mandatory; otherwise prefer TO-220-3 for thermal performance. |
Compared with MBR20150CT-G1 and MBR20150CTF-E1, the MBR20150CT-E1 offers optimal thermal performance in non-isolated, RoHS-compliant power supplies-delivering lowest RθJC and highest efficiency where heatsink grounding is acceptable and full "Green" certification is not required.

FAQ
What is the maximum allowable case temperature for continuous operation?
The MBR20150CT-E1 supports continuous operation up to TC = +134°C, as specified in its Absolute Maximum Ratings table. At this temperature, each diode leg maintains its 10 A average forward current rating. Derating is required above this point, and thermal design must ensure junction temperature stays ≤ +150°C under worst-case load and ambient conditions.
Can this device replace a single 20 A Schottky in a non-dual configuration?
No - the MBR20150CT-E1 contains two independent 10 A diodes with a shared cathode; it cannot be used as a single 20 A device. Using only one anode (A1 or A2) while leaving the other open yields only 10 A capacity and risks imbalance. For single-anode 20 A applications, select a monolithic 20 A Schottky such as the MBR20150CT (non-dual variant, if available) or equivalent.
Is the TO-220-3 package electrically insulated from the heatsink?
No - the TO-220-3 (2) package has an electrically conductive metal tab (connected to the cathode terminal K). Direct mounting to a grounded heatsink creates a shorted cathode path. Electrical isolation requires insulating hardware (e.g., mica washer + nylon screw) or use of the TO-220F-3 variant, which features a fully insulated plastic body.
Does this part meet automotive AEC-Q101 qualification?
No - the MBR20150CT-E1 is not AEC-Q101 qualified. Diodes Incorporated lists it for industrial, computing, and communications applications only. For automotive-grade dual Schottky rectifiers, consider the AEC-Q101 qualified MBR20150CTQ series or equivalent qualified alternatives from STMicroelectronics or ON Semiconductor.
