Product details
Overview
MBRS20100CT-Y MNG from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 100V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and maximum junction temperature of 150°C. It delivers low forward voltage drop (0.95V max at 20A, 25°C) and high thermal efficiency, serving as a primary output rectifier in high-frequency DC/DC converters.
For engineers reviewing the MBRS20100CT-Y MNG datasheet, MBRS20100CT-Y MNG pinout, MBRS20100CT-Y MNG application, or MBRS20100CT-Y MNG equivalent, key selection criteria include its 100V VRRM rating, dual-common-cathode configuration, 2.0°C/W junction-to-case thermal resistance, moisture sensitivity level 1 compliance, and suitability for automated SMT placement in power supply designs.
Technical Context
This device integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection. Its architecture enables synchronous rectification in center-tapped or full-wave bridge topologies while maintaining low conduction loss across operating temperatures up to 150°C.
The MBRS20100CT-Y MNG exhibits a typical reverse leakage current of ≤5mA at 100V and 125°C, and supports critical dv/dt capability of 10,000 V/μs - essential for noise-immune operation in fast-switching SMPS environments where voltage transients are prevalent.

FAQ
What is the maximum junction temperature rating for MBRS20100CT-Y MNG?
The MBRS20100CT-Y MNG has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows sustained operation in thermally demanding environments such as enclosed industrial power modules. Derating curves confirm usable average current down to ~12A at 125°C case temperature. The MBRS20100CT-Y MNG must be mounted on adequate copper area to maintain junction temperature within limits under full-load conditions.
Does MBRS20100CT-Y MNG support automated SMT placement?
Yes, the MBRS20100CT-Y MNG is explicitly designed for automated surface-mount placement. Its TO-263AB (D2PAK) package features matte tin-plated leads compliant with J-STD-002, and its moisture sensitivity level is rated MSL-1 - meaning no baking is required before reflow. The device's symmetrical lead geometry and standardized tape-and-reel packaging (800 per reel) ensure reliable pick-and-place yield. The MBRS20100CT-Y MNG is widely deployed in high-throughput manufacturing lines for server PSUs and consumer adapters.
What is the reverse leakage current specification for MBRS20100CT-Y MNG at elevated temperature?
At 100V reverse voltage and 125°C junction temperature, the MBRS20100CT-Y MNG exhibits a maximum reverse leakage current (IR) of 5 mA per diode, as specified in the Electrical Specifications table. This value is critical for standby power budgeting in energy-efficient designs. At 25°C, IR is limited to 100 µA. The MBRS20100CT-Y MNG maintains this performance across its full rated temperature range without parameter drift beyond datasheet limits.
Is MBRS20100CT-Y MNG halogen-free and RoHS compliant?
Yes, the MBRS20100CT-Y MNG uses a halogen-free molding compound compliant with IEC 61249-2-21 and is fully RoHS compliant per EU Directive 2011/65/EU. These environmental qualifications are confirmed in the "Features" section of the Taiwan Semiconductor datasheet and verified through material declarations. The MBRS20100CT-Y MNG meets regulatory requirements for consumer, industrial, and networking equipment sold in global markets including the EU, Japan, and South Korea.
What is the thermal resistance from junction to case (RθJC) for MBRS20100CT-Y MNG?
The MBRS20100CT-Y MNG has a junction-to-case thermal resistance (RθJC) of 2.0°C/W, measured under standard test conditions per JEDEC JESD51-14. This value applies to all variants in the MBRS2090CT through MBRS20150CT series. Effective thermal design requires low-impedance thermal vias and ≥4 cm² of 2-oz copper connected to the cathode pad. The MBRS20100CT-Y MNG's RθJC enables direct thermal coupling to heatsinks or internal PCB planes without auxiliary thermal interface materials in most medium-power applications.
