Product details
Overview
MBR20200CT-E1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220-3 package, rated for 200 V reverse voltage, 10 A average forward current per diode leg (20 A total), 0.90 V max forward voltage at 10 A and +25°C, and 0.05 mA max reverse leakage at rated DC voltage and +25°C. It serves as output rectification in medium-voltage, high-frequency switch-mode power supplies where low switching loss and EMI suppression are critical.
For engineers reviewing the MBR20200CT-E1 datasheet, MBR20200CT-E1 pinout, MBR20200CT-E1 application, or MBR20200CT-E1 equivalent, key selection criteria include dual-diode thermal coupling in shared case, junction temperature rating up to +150°C, guard-ring stress protection, RoHS-compliant matte tin finish, and validated surge capacity of 150 A non-repetitive peak.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal (Pin 2), enabling synchronous or interleaved rectification topologies without external parallel wiring. Its low VF and fast recovery eliminate minority-carrier storage delay, making it suitable for 100–500 kHz SMPS designs where conduction loss dominates over switching loss.
The TO-220-3 mechanical construction provides direct heatsink mounting via Pin 2 (cathode tab), with RθJC = 2.0°C/W and maximum TJ = +150°C. Guard-ring structure enhances ruggedness against transient overvoltage and localized avalanche stress during line surges or inductive kickback events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands repetitive reverse voltage up to 200 V without breakdown; sets usable input/output voltage range in buck-derived converters. |
| IF(AV) per leg | 10 A - Sustains continuous DC forward current of 10 A per diode at TC = +133°C; defines thermal design margin for 20 A dual-leg output stage. |
| VF @ 10 A, +25°C | 0.90 V - Low conduction loss yields ~9 W total dissipation at full load (2 × 10 A × 0.9 V); reduces heatsink requirements vs. standard PN rectifiers. |
| IR @ VR, +25°C | 0.05 mA - Ultra-low leakage preserves efficiency in standby mode and minimizes thermal runaway risk in parallel configurations. |
| IFSM | 150 A - Handles single half-sine surge events (60 Hz, rated load) without degradation; supports inrush current limiting in AC/DC front-ends. |
| TJ max | +150°C - Enables operation in high-ambient industrial environments; requires thermal interface design targeting ≤130°C case temperature at full load. |
| RθJC | 2.0°C/W - Junction-to-case thermal resistance enables direct heatsink attachment; mandates ≥10 cm² copper pad area for 10 A/leg sustained operation. |
Pinout & Package
Package: TO-220-3 (2), molded plastic case with isolated mounting tab (Pin 2), matte tin-plated copper leadframe, UL 94V-0 flammability rating, weight ≈1.95 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 (A1) | Input terminal for first diode leg; connects to transformer secondary or switching node in center-tapped or dual-output topology. |
| 2 | Cathode (K) | Common cathode output node and electrically isolated metal tab; primary thermal path to heatsink; must be DC-grounded or connected to output rail. |
| 3 | Anode 2 (A2) | Input terminal for second diode leg; enables dual-output or phase-interleaved rectification without external cathode tie. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.90 V @ 10 A, +25°C - Reduces conduction loss by >40% versus comparable 200 V PN rectifiers, improving 12 V/24 V output efficiency by 1.2–1.8%. |
| Guard-ring protected junction | Enhanced edge termination withstands dv/dt up to 10,000 V/µs - Prevents premature avalanche failure during fast-switching transients in LLC resonant converters. |
| High surge capacity | 150 A IFSM (half-wave, 60 Hz) - Supports 3× rated output current surges during cold-start or capacitor charging without parameter shift. |
| Pb-free & Green packaging | RoHS-compliant matte tin finish; halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - Meets IPC-1752A Tier 1 reporting and automotive ELV requirements. |
Applications

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 |
|---|---|---|---|
| MBR20200CT-G1 | Same electrical specs and TO-220-3 package; uses halogen/antimony-free "Green" molding compound (Br+Cl <1500 ppm, Sb <1000 ppm). | Required for strict environmental compliance in EU medical or automotive programs mandating full halogen-free certification. | Select G1 when RoHS + halogen-free documentation (IPC-1752A) is contractually required; E1 remains valid for general industrial use. |
| MBR20200CTF-E1 | Identical electrical specs but TO-220F-3 (full-pack) package: insulated case, RθJC = 2.5°C/W, weight 1.69 g, no mounting hole. | Suitable for space-constrained designs requiring isolation from chassis ground or conformal coating compatibility. | Choose TO-220F-3 variant when electrical isolation >500 V RMS is needed between cathode tab and heatsink, or when board-level insulation is mandatory. |
Compared with MBR20200CT-G1, the E1 variant offers identical performance with standard RoHS compliance but lacks halogen-free traceability; versus MBR20200CTF-E1, the TO-220-3 version delivers lower thermal resistance and mechanical stability for high-power, heatsink-mounted deployments.

FAQ
What is the maximum allowable case temperature for continuous operation?
The MBR20200CT-E1 is rated for IF(AV) = 10 A per diode leg at TC = +133°C. To maintain reliability and avoid thermal runaway, case temperature must not exceed +133°C under full load. Derating curves show 20 A total current drops to 14 A at TC = +100°C and 8 A at TC = +125°C, based on thermal resistance and ambient conditions.
Can this part replace a single 20 A Schottky rectifier in a center-tapped transformer design?
Yes - the MBR20200CT-E1's dual-anode, common-cathode configuration is purpose-built for center-tapped transformer rectification. Pins 1 and 3 serve as independent anodes tied to opposite transformer ends, while Pin 2 (cathode) delivers the combined output, eliminating the need for external cathode paralleling and ensuring matched thermal behavior between legs.
Is the TO-220-3 mounting tab electrically isolated?
No - the metal tab (Pin 2, cathode) is electrically connected to the internal common cathode structure and is not insulated. It must be mounted to a heatsink that is either floating or referenced to the output rail. For isolated mounting, the TO-220F-3 variant (MBR20200CTF-E1) provides full-case insulation rated to 2500 V RMS.
Does this device require a minimum load or snubber circuit?
No - as a majority-carrier Schottky device, the MBR20200CT-E1 has no reverse recovery time (trr ≈ 0 ns) and generates negligible switching noise. Snubbers are unnecessary unless system-level EMI testing reveals conducted emissions above limits; its 10,000 V/µs dv/dt rating inherently suppresses voltage overshoot during hard switching.
