Product details
Overview
MBR15100CTF-E1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 7.5 A per diode leg (15 A total), and 0.85 V max forward voltage at 7.5 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR15100CTF-E1 datasheet, MBR15100CTF-E1 pinout, MBR15100CTF-E1 application, or MBR15100CTF-E1 equivalent, key selection criteria include thermal resistance (RθJC = 4.5°C/W), surge current capability (150 A non-repetitive), junction temperature rating (+150°C), RoHS-compliant lead-free finish, and guard-ring stress protection.
Technical Context
This dual Schottky rectifier integrates two independent anode terminals (A1, A2) sharing a common cathode (K), enabling synchronous or interleaved rectification in dual-rail or center-tapped topologies. Its low VF and fast recovery support high-efficiency, high-frequency operation up to 20 kHz square-wave conditions.
The device uses a guard-ring structure to enhance ruggedness against transient overvoltage and thermal stress. Its TO-220F-3 package features insulated mounting flange (non-conductive backside), allowing direct heatsink attachment without electrical isolation hardware while maintaining RθJC = 4.5°C/W.

IC Role / Device Role / Timing Role: High-frequency rectifier in quasi-resonant flyback secondary, minimizing switching noise coupling into analog current sense circuitry. Use Value: Low IR (0.1 mA @ 25°C) prevents standby power loss, and fast soft recovery avoids EMI spikes during zero-cross transitions. |
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-MBR15100CT | Same 100 V / 7.5 A per leg rating; VF = 0.87 V @ 7.5 A; TO-220-3 (conductive flange); RθJC = 2.5°C/W. | Requires insulating kit for heatsink mounting; better thermal performance but higher assembly cost and complexity. | Select when maximum thermal conductivity is prioritized and isolation hardware is acceptable. |
| ON Semiconductor MBR16100CT | 16 A total (8 A per leg); VF = 0.82 V @ 8 A; TO-220-3; RθJC = 2.0°C/W; no guard ring. | Higher current headroom but lacks guard-ring ruggedness; less suitable for surge-prone industrial mains inputs. | Select for higher-current designs where transient immunity is managed upstream via TVS/clamping. |
Compared with VS-MBR15100CT and MBR16100CT, MBR15100CTF-E1 trades slightly higher RθJC for simplified mechanical integration (no insulator needed) and superior transient robustness-ideal for cost-sensitive, space-constrained, and reliability-critical power supplies.

FAQ
What is the maximum case temperature for continuous operation?
The MBR15100CTF-E1 supports continuous operation up to TC = +122°C for its rated 7.5 A average forward current per diode leg. This is derived from the thermal limit where junction temperature remains ≤ +150°C given RθJC = 4.5°C/W and typical heatsink interface conditions. Exceeding this requires derating per Figure 3 in the datasheet.
Can MBR15100CTF-E1 be used in place of a single-diode TO-220 Schottky?
No-it is a dual-anode, common-cathode device. Using only one anode (A1 or A2) leaves the unused anode floating, risking unpredictable behavior. For single-diode replacement, use MBR10100CTF-E1 (10 A, same package). The MBR15100CTF-E1 must be applied in dual-rail or interleaved topologies to utilize both legs properly.
Is the TO-220F-3 flange electrically isolated from all pins?
Yes-the TO-220F-3 package has an insulated flange that is not internally connected to any pin. The flange is molded plastic with no metallic conduction path to pins 1 (A1), 2 (K), or 3 (A2), enabling direct mounting to grounded heatsinks without short-circuit risk or need for mica washers.
How does the guard-ring structure improve reliability?
The guard-ring mitigates edge breakdown under high dv/dt or reverse-biased transients by redistributing electric field concentration away from the active junction periphery. This increases the device's ability to survive repetitive 10,000 V/µs voltage slew rates and ESD events (>8 kV HBM), making it suitable for noisy industrial and telecom power environments.
