Taiwan Semiconductor Corporation MBRS15150CTH

Overview

MBRS15150CTH from Taiwan Semiconductor is a 15 A, 150 V dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for high-frequency DC/DC conversion and reverse battery protection with 0.95 V forward voltage at 7.5 A and 25°C, 5 mA reverse leakage at 150 V and 125°C, and 150 A surge capability.

For engineers reviewing the MBRS15150CTH datasheet, MBRS15150CTH pinout, MBRS15150CTH application, or MBRS15150CTH equivalent, key selection criteria include peak repetitive reverse voltage (150 V), thermal resistance (2°C/W junction-to-case), AEC-Q101 qualification, guard ring overvoltage protection, and TO-263AB mechanical compatibility for automotive-grade power designs.

Technical Context

This dual-die Schottky rectifier integrates two independent anode-cathode structures in a single TO-263AB thermally enhanced surface-mount package, enabling shared heatsinking and compact layout for bidirectional or dual-rail freewheeling paths. Its low VF and fast recovery support high-efficiency operation in switching frequencies up to several hundred kHz.

The device features a guard ring structure to improve ruggedness against transient overvoltage events, and its JESD201 Class 2 whisker resistance and moisture sensitivity level 1 rating ensure reliability in automated SMT assembly and harsh automotive environments.

FAQ

What is the maximum junction temperature rating for MBRS15150CTH?

The MBRS15150CTH has a maximum junction temperature (TJ max) of +150°C, as specified in its absolute maximum ratings table. This rating enables operation in under-hood automotive environments where ambient temperatures may reach 105°C and power dissipation must be managed via proper PCB copper area and thermal vias. The device's 2°C/W junction-to-case thermal resistance supports effective heat transfer to the board or heatsink, ensuring MBRS15150CTH remains within safe operating limits even under sustained 15 A load conditions.

Is MBRS15150CTH qualified for automotive applications?

Yes, MBRS15150CTH is explicitly AEC-Q101 qualified per the manufacturer's documentation, confirming compliance with stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and electrostatic discharge (ESD). This qualification validates MBRS15150CTH for use in automotive power electronics such as body control modules, lighting drivers, and DC/DC converters where reliability under thermal, mechanical, and electrical stress is mandatory.

What does the "H" suffix in MBRS15150CTH indicate?

The "H" suffix in MBRS15150CTH denotes halogen-free construction per IEC 61249-2-21, confirmed in the product's mechanical and environmental specifications. It distinguishes this variant from non-halogen-free equivalents (e.g., MBRS15150CT) and ensures compliance with automotive OEM material declarations and end-of-life recycling requirements. All MBRS15150CTH units meet RoHS and J-STD-020 moisture sensitivity level 1 standards.

How does the dual-die configuration of MBRS15150CTH benefit PCB layout?

The dual-die configuration of MBRS15150CTH integrates two independent Schottky diodes into a single TO-263AB package with a shared cathode terminal, reducing component count and minimizing interconnect inductance between parallel rectifiers. This layout advantage cuts PCB area by ~40% versus two discrete TO-263 devices and simplifies thermal management via one large copper pour under the exposed cathode pad-directly improving thermal performance and signal integrity in high-current MBRS15150CTH applications.

What is the forward voltage of MBRS15150CTH at elevated temperature?

At 7.5 A and 125°C junction temperature, the MBRS15150CTH exhibits a typical forward voltage (VF) of 0.92 V per diode, as documented in the electrical specifications table. This value reflects the positive temperature coefficient of Schottky diodes and is critical for thermal stability analysis-ensuring that MBRS15150CTH conduction losses do not escalate uncontrollably during high-temperature operation in enclosed automotive enclosures.
