Product details
Overview
MBR30100CT-E1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220-3 package, rated for 100 V reverse voltage, 15 A average forward current per diode leg (30 A total), and 0.85 V max forward voltage at 15 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR30100CT-E1 datasheet, MBR30100CT-E1 pinout, MBR30100CT-E1 application, or MBR30100CT-E1 equivalent, key selection criteria include its dual-diode configuration with shared cathode, thermal resistance of 2.5°C/W (junction-to-case), 200 A non-repetitive surge rating, +150°C junction temperature limit, and RoHS-compliant lead-free finish.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220-3 package with a common cathode (Pin 2), enabling synchronous or interleaved output rectification in dual-rail or center-tapped topologies. Its guard-ring structure enhances ruggedness against transient overvoltage stress.
Designed for medium-voltage, high-frequency operation, it avoids minority-carrier storage delay-eliminating reverse recovery charge (Qrr = 0)-and supports efficient power conversion up to several hundred kHz. The 10,000 V/μs dv/dt rating confirms robustness in fast-switching environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode withstands without breakdown. |
| IF(AV) per leg | 15 A - Continuous DC forward current per diode at TC = +107°C; enables 30 A total dual-leg output capability. |
| VF (max) | 0.85 V @ 15 A, +25°C - Low conduction loss reduces heat generation and improves efficiency in high-current rails. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Minimal leakage preserves regulation and stability in standby or light-load conditions. |
| RθJC | 2.5°C/W - Thermal resistance from junction to case; requires heatsink mounting for sustained 30 A operation. |
| IFS M | 200 A - Non-repetitive surge current handling for brief overload or startup events without failure. |
| TJ range | –55°C to +150°C - Wide operating junction temperature supports industrial and enclosed power supply environments. |
Pinout & Package
Package: TO-220-3 (2), molded plastic with matte tin–annealed copper leadframe, UL 94V-0 rated, 1.95 g weight. Lead-free, RoHS-compliant, halogen- and antimony-free ("Green").
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode Leg 1 | Input terminal for first rectifier path; electrically isolated from A2 and K. |
| 2 (K) | Common Cathode | Shared output node for both diodes; must be connected to system ground or output rail return. |
| 3 (A2) | Anode of Diode Leg 2 | Input terminal for second independent rectifier path; enables dual-output or phase-split designs. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.85 V @ 15 A, +25°C - Reduces I²R losses by ~30% vs. comparable silicon rectifiers at same current. |
| Guard-ring protection | Integrated edge termination - Improves reliability under voltage transients and mechanical stress during PCB assembly. |
| +150°C TJ rating | Maximum junction temperature - Allows operation in thermally constrained enclosures without derating below 15 A per leg. |
| No reverse recovery charge | Qrr = 0 - Eliminates switching spikes and EMI in high-frequency converters; simplifies snubber design. |
Applications
| Server Power Supply Output Rectification | Industrial AC-DC Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR30100CT-G1 | Same electrical specs; "Green" package (halogen/antimony free), identical TO-220-3 outline. | Required where halogen-free compliance is mandated (e.g., EU medical, automotive). | Select G1 when full "Green" material declaration is contractually required; E1 suffices for standard RoHS. |
| MBR30100CTF-E1 | TO-220F-3 (full-pack) variant; higher RθJC (4.5°C/W); same die, lower thermal performance. | Suitable for space-constrained layouts where insulated mounting is needed; not for high-power continuous use. | Choose TO-220F only if electrical isolation from heatsink is mandatory; otherwise prefer TO-220-3 (E1) for thermal superiority. |
Compared with MBR30100CT-G1 and MBR30100CTF-E1, the MBR30100CT-E1 offers optimal thermal performance in standard through-hole mounting while meeting baseline RoHS requirements-making it the preferred choice for cost-sensitive, high-efficiency industrial and computing power supplies.

FAQ
What is the maximum case temperature for continuous operation?
The MBR30100CT-E1 supports continuous operation at TC = +107°C for full 15 A per leg rating. Derating begins above this point per Figure 3 in DS36946; at TC = +125°C, IF(AV) drops to ~12.5 A per leg. Thermal design must ensure case temperature stays within this limit using appropriate heatsinking.
Is the MBR30100CT-E1 suitable for surface-mount reflow assembly?
No - the TO-220-3 package is through-hole only and not rated for standard SMT reflow profiles. Its plastic body and leadframe geometry require wave soldering or hand soldering. For SMT alternatives, consider Diodes' APD30100CTW-Q or similar D2PAK-3L devices.
Does this part have a specified reverse recovery time (trr)?
No - as a Schottky rectifier, the MBR30100CT-E1 has no minority-carrier storage and therefore no defined trr. Its switching behavior is governed solely by junction capacitance and circuit inductance; reverse recovery charge Qrr is zero, eliminating associated losses and EMI.
Can Pin 2 (K) be used as a thermal pad connection?
No - Pin 2 is the electrical common cathode terminal, not a dedicated thermal pad. Thermal transfer occurs via the metal tab (attached to Pin 2 internally) mounted to a heatsink. The tab must be electrically isolated if the heatsink is grounded elsewhere, but Pin 2 itself carries full output current and must be routed accordingly.
