Product details
Overview
MBR20H100CTF-E1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 10 A average forward current per diode leg, and 0.77 V max forward voltage at 10 A and +25°C. It delivers low switching losses and low noise in high-frequency switch-mode power supplies.
For engineers reviewing the MBR20H100CTF-E1 datasheet, MBR20H100CTF-E1 pinout, MBR20H100CTF-E1 application, or MBR20H100CTF-E1 equivalent, this device supports medium-voltage, high-efficiency DC output rectification where thermal robustness (+175°C junction), surge tolerance (250 A IFSM), and RoHS-compliant green packaging are critical selection criteria.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V / 10 A diode legs sharing a single cathode terminal. Its guard-ring structure enhances ruggedness against transient overvoltage stress, while the low VF enables reduced conduction loss in high-frequency converters operating up to 20 kHz square-wave conditions.
The device is thermally optimized for mounting on heatsinks: RθJC is 2.5°C/W (TO-220F-3), enabling reliable operation at TJ = +175°C with controlled case temperature. ESD ratings exceed 400 V (machine model) and 8 kV (human body model), supporting robust handling in automated assembly environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode leg withstands without breakdown. |
| IF(AV) per leg | 10 A - Continuous average forward current per diode at TC = +162°C, defining usable DC output capacity. |
| VF (max) | 0.77 V @ 10 A, +25°C - Low conduction loss directly reduces power dissipation and improves efficiency in SMPS outputs. |
| IR (max) | 0.0045 mA @ 100 V, +25°C - Ultra-low leakage preserves regulation in standby and light-load conditions. |
| IFSM | 250 A - Non-repetitive surge rating ensures survival during AC line transients or inrush events. |
| TJ (max) | +175°C - High junction temperature capability allows compact thermal design with reduced heatsink mass. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH05-M3 | Same 100 V VRRM, but 0.82 V VF @ 10 A (+25°C); TO-247AC package; higher RθJC (1.5°C/W) but larger footprint. | Preferred where higher surge margin (300 A IFSM) and lower thermal resistance justify larger board area. | Select when heatsink interface demands lower RθJC and board space permits TO-247AC. |
| ON Semiconductor MBR20100CT | Identical electrical specs (100 V, 10 A/leg, 0.77 V VF), but TO-220-3 (non-isolated back); RθJC = 2.0°C/W. | Suitable where mechanical isolation is unnecessary and lower thermal resistance is prioritized over creepage/clearance. | Choose when cost-sensitive designs accept exposed metal tab and require best-in-class RθJC. |
Compared with VS-20CPH05-M3 and MBR20100CT, MBR20H100CTF-E1 uniquely combines TO-220F-3 insulation, green compliance, and balanced thermal-electrical performance-ideal for space-constrained, safety-critical, and environmentally regulated power systems.

FAQ
What is the thermal resistance from junction to case (RθJC) for MBR20H100CTF-E1?
The RθJC for MBR20H100CTF-E1 in TO-220F-3 package is 2.5°C/W, measured under standard JEDEC test conditions with proper heatsink mounting. This value enables accurate junction temperature calculation using TJ = TC + (Pd × RθJC), where Pd is total power dissipation across both diode legs.
Can MBR20H100CTF-E1 replace standard silicon rectifiers in existing 100 V designs?
Yes, provided the circuit operates below 20 kHz and does not rely on silicon's higher reverse recovery time for snubber function. MBR20H100CTF-E1 eliminates reverse recovery loss, reducing EMI and improving efficiency-but requires verifying layout parasitics due to faster switching edges.
Is the TO-220F-3 package electrically insulated?
Yes-the TO-220F-3 package features a fully molded, insulated back surface that provides electrical isolation between the die attach pad and heatsink. This eliminates need for insulating washers and supports direct mounting to grounded heatsinks in Class I systems.
What is the maximum allowable case temperature (TC) for continuous 10 A operation per leg?
Per the datasheet's derating curve (Figure 4), the maximum case temperature for continuous 10 A average current per leg is +162°C. Operation above this requires proportional current derating; at TC = +100°C, IF(AV) per leg is rated at ~14.5 A.
