Product details

Overview

MBR2035CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in TO-220AB package, rated for 20A average forward current, 35V repetitive peak reverse voltage, and 150A non-repetitive surge current. It delivers low forward voltage (0.84V at 20A, 25°C) and operates up to 150°C junction temperature, serving as output rectifier in automotive-grade DC-DC converters.

For engineers reviewing the MBR2035CTH datasheet, MBR2035CTH pinout, MBR2035CTH application, or MBR2035CTH equivalent, key selection criteria include its AEC-Q101 qualification, 1 °C/W junction-to-case thermal resistance, guard ring–enabled overvoltage protection, and compatibility with high-efficiency SMPS designs requiring low conduction loss and robust surge handling.

Technical Context

This device integrates two independent Schottky diodes in a single TO-220AB package with common cathode configuration (dual common-cathode topology). Its low V_F and absence of minority-carrier storage enable zero reverse recovery time, eliminating switching losses in high-frequency power conversion stages.

The MBR2035CTH features a guard ring structure to suppress edge breakdown and sustain dv/dt up to 10,000 V/μs. Thermal performance is optimized via direct die-to-case mounting, supporting continuous 20A operation with appropriate heatsinking per its 1 °C/W R_θJC.

FAQ

What does the "H" suffix in MBR2035CTH signify?

The "H" suffix in MBR2035CTH indicates full AEC-Q101 qualification per Rev D requirements, covering high-temperature operating life, temperature cycling, and unbiased high-humidity storage tests. This certification confirms MBR2035CTH's suitability for automotive powertrain and chassis applications where reliability under extreme environmental stress is mandatory.

Is MBR2035CTH pin-compatible with non-AEC-Q101 versions like MBR2035CT?

Yes, MBR2035CTH shares identical TO-220AB mechanical dimensions, pinout, and solder pad layout with MBR2035CT. Both use the same three-terminal common-cathode configuration with center-tab cathode. No PCB redesign is needed when upgrading from MBR2035CT to MBR2035CTH for automotive qualification.

What is the maximum recommended case temperature for continuous 20A operation of MBR2035CTH?

With its 1 °C/W junction-to-case thermal resistance and 150°C maximum junction temperature, MBR2035CTH supports continuous 20A operation up to 130°C case temperature (150°C − (20A² × R_DS(on) × 1 °C/W)). Actual limit depends on measured forward voltage drop; at 0.84 V, power dissipation is ~16.8 W, allowing ≤133°C case temp with adequate heatsinking.

Does MBR2035CTH have a specified reverse recovery time (t_rr)?

No-MBR2035CTH is a Schottky barrier rectifier and exhibits no minority-carrier storage; therefore, it has no defined reverse recovery time. Its switching behavior is governed solely by junction capacitance and circuit inductance, enabling clean commutation in high-frequency converters without reverse recovery spikes or associated EMI.

Can MBR2035CTH be used in parallel configurations to increase current capacity?

Parallel operation of MBR2035CTH devices is not recommended without individual current-sharing resistors or active balancing, due to forward voltage mismatch between units (±5% typical). For >20A requirements, select higher-current variants like MBR3035CTH or use multiphase topologies with dedicated current-balancing control.
