Taiwan Semiconductor Corporation MBRF1635H

Overview

MBRF1635H from Taiwan Semiconductor is a 16A, 35V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.63V max forward voltage at 16A/25°C, 150A surge current capability, and guard ring over-voltage protection-used in automotive-grade DC-DC converters and SMPS secondary-side rectification.

For engineers reviewing the MBRF1635H datasheet, MBRF1635H pinout, MBRF1635H application, or MBRF1635H equivalent, key selection criteria include its AEC-Q101 qualification, low VF at high IF, TJ = 150°C rating, ITO-220AC thermal performance (RθJC = 3°C/W), and UL recognition (E-326243).

Technical Context

This single-die Schottky rectifier operates with no minority-carrier storage delay, enabling high-frequency switching in DC-DC topologies. Its 10,000 V/µs dv/dt rating supports fast transient immunity in noisy automotive environments.

The device uses matte tin-plated leads compliant with J-STD-002 solderability and passes JESD201 Class 2 whisker testing. Polarity is marked on the case, and the molding compound meets UL 94V-0 flammability standard.

FAQ

What does the "H" suffix in MBRF1635H signify?

The "H" suffix in MBRF1635H indicates full AEC-Q101 qualification per the Taiwan Semiconductor specification K2105. This includes stress testing for high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing-making MBRF1635H suitable for automotive power modules where reliability is critical.

Is MBRF1635H pin-compatible with standard TO-220 rectifiers?

MBRF1635H uses the ITO-220AC package, which shares the same outline and mounting hole pattern as TO-220AB but features an electrically isolated tab. While mechanical fit is identical, the isolated tab eliminates need for insulating hardware-so MBRF1635H can replace TO-220AB parts in heatsink-mounted designs only if electrical isolation is confirmed beneficial for the circuit.

What is the maximum recommended case temperature for continuous operation of MBRF1635H?

The MBRF1635H is rated for continuous operation up to TC = 100°C, derived from its 16A average forward current rating at that temperature. Exceeding 100°C case temperature requires derating per the forward current derating curve in the datasheet; at TC = 125°C, IF must be reduced to approximately 12A to maintain reliability.

Does MBRF1635H require a minimum heatsink size for 16A operation?

Yes-MBRF1635H requires a heatsink capable of maintaining TC ≤ 100°C at 16A. With RθJC = 3°C/W and typical RθCS + RθSA ≈ 1.5°C/W, a total thermal resistance of ≤4.5°C/W is needed. For ambient TA = 70°C, this implies a heatsink with ≥12 cm² surface area and forced airflow or equivalent thermal interface.

How does the guard ring in MBRF1635H improve robustness compared to standard Schottky diodes?

The guard ring in MBRF1635H mitigates edge breakdown under high dv/dt or transient overvoltage by distributing electric field stress away from the active junction periphery. This allows MBRF1635H to sustain rated 35V VRRM even during 10,000 V/µs transients-critical for reliable operation in automotive CAN/LIN bus power stages and motor drive snubbers.
