Diodes Incorporated MBR20200CTF-E1

Overview

MBR20200CTF-E1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220F-3 package, rated for 200 V reverse voltage, 10 A per diode leg (20 A total), and 0.90 V max forward voltage at 10 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output stages, with 150°C junction temperature rating and guard-ring stress protection.

For engineers reviewing the MBR20200CTF-E1 datasheet, MBR20200CTF-E1 pinout, MBR20200CTF-E1 application, or MBR20200CTF-E1 equivalent, key selection criteria include dual-leg thermal derating behavior, TO-220F-3 thermal resistance (2.5°C/W junction-to-case), RoHS-compliant matte tin finish, and surge capability up to 150 A non-repetitive peak.

Technical Context

This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous or interleaved rectification in dual-rail or center-tapped topologies. Its low VF and absence of minority-carrier storage enable operation at >100 kHz without reverse recovery loss penalties.

The TO-220F-3 package features insulated mounting flange and 2.5°C/W R_θJC, supporting direct heatsink attachment without isolation hardware. Guard-ring structure mitigates edge breakdown under high dv/dt (10,000 V/µs rated) and high-temperature reverse bias.

Key Specifications

Pinout & Package

Package: TO-220F-3 (insulated flange, 3-terminal, vertical mount). Flange is electrically isolated from all terminals and serves as mechanical anchor and thermal path.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky rectifier applications.

Compared with MBR20200CTF-E1, MBR20200CT-LJ offers superior thermal resistance but adds insulation complexity, while SS20200CT trades surge robustness and edge reliability for lower cost-making the E1 variant optimal for industrial-grade 20 A rectification where long-term reliability under transient stress is mandatory.

FAQ

What is the maximum case temperature for continuous operation?

The MBR20200CTF-E1 supports continuous operation up to +133°C case temperature per diode leg, as specified in its IF(AV) rating. At this temperature, each leg delivers 10 A average forward current. Exceeding +133°C reduces allowable current per the derating curve in Figure 3 of DS36948 Rev. 3–2.

Can MBR20200CTF-E1 replace MBR20200CT-E1 in existing designs?

Yes, but with thermal trade-offs: MBR20200CTF-E1 uses TO-220F-3 (insulated flange, R_θJC = 2.5°C/W), while MBR20200CT-E1 uses TO-220-3 (non-insulated, R_θJC = 2.0°C/W). The F-version eliminates need for insulating hardware but has slightly higher junction-to-case resistance-requiring verification of heatsink interface and ambient conditions.

Is the common cathode pin (Pin 2) rated for full 20 A combined current?

No-Pin 2 (K) carries the sum of both anode currents, but its current-carrying capacity is limited by internal bond wire and leadframe design. The datasheet specifies 20 A total output, and Diodes' layout guidelines require ≥1.5 mm wide copper pour on K-pin traces to sustain full load without excessive heating or voltage drop.

Does the "E1" suffix guarantee RoHS compliance?

Yes-the "E1" suffix explicitly denotes Diodes Incorporated's RoHS-compliant products per EU Directive 2011/65/EU (RoHS 2), with lead-free matte tin plating on terminals and full exemption documentation available on diodes.com/quality/lead_free.html. This applies to both TO-220-3 and TO-220F-3 variants bearing the E1 suffix.
