Product details
Overview
MSCDR90A160BL1NG from Microchip Technology is a 1600 V, 90 A phase leg rectifier diode power module built with silicon carbide (SiC) technology, featuring ultra-low stray inductance and a Si₃N₄ substrate with thick copper for enhanced thermal performance. It delivers high-efficiency AC/DC and DC/AC conversion in motor control inverters and high-reliability industrial power systems.
For engineers reviewing the MSCDR90A160BL1NG datasheet, MSCDR90A160BL1NG pinout, MSCDR90A160BL1NG application, or MSCDR90A160BL1NG equivalent, this page provides verified electrical ratings, thermal resistance data, isolation voltage specs, mounting torque requirements, and real-world use context for high-power SiC rectification design.
Technical Context
This device integrates two series-connected SiC Schottky diodes in a single-phase leg configuration, enabling bidirectional blocking and unidirectional conduction per leg. Its isolated package supports direct heatsink mounting with 2500 V RMS isolation and 0.468 °C/W junction-to-heatsink thermal resistance.
The module operates across –55°C to +150°C junction temperature range and sustains 850 A non-repetitive surge current at 10 ms, optimized for hard-switching PFC and inverter freewheeling paths where low reverse recovery loss and minimal voltage overshoot are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-leg rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXYSM160B160D1 | 1600 V, 160 A rating; TO-247-3L discrete dual-diode; higher thermal resistance (0.65 °C/W). | Requires external isolation and separate heatsinking; not suitable for space-constrained modules. | Choose when board-level layout flexibility is prioritized over thermal density and integrated isolation. |
| Infineon IDH16G65C5 | 650 V, 16 A SiC diode in TO-247; lower voltage rating and current capacity; no integrated phase-leg topology. | Limited to sub-10 kW designs; requires two devices per leg and external gate drive coordination. | Choose only for prototyping or low-power evaluation where cost-per-amp is secondary to component availability. |

FAQ
What is the maximum junction temperature rating for MSCDR90A160BL1NG?
The MSCDR90A160BL1NG has a maximum operating junction temperature of +150°C and a recommended switching junction temperature limit of TJmax–25°C (i.e., ≤125°C) to ensure long-term reliability under repetitive stress. This rating is confirmed in Table 1-3 of the official DS00004106A datasheet and applies directly to the MSCDR90A160BL1NG device under all specified test conditions.
Does MSCDR90A160BL1NG include internal current sensing capability?
Yes, MSCDR90A160BL1NG features two dedicated Kelvin sense terminals - CR1 and CR2 - each associated with one of its integrated SiC diodes. These terminals enable accurate, low-error forward current measurement independent of power path voltage drop, a capability explicitly documented in the pinout diagram and electrical specifications section of the DS00004106A datasheet for MSCDR90A160BL1NG.
What is the isolation voltage specification for MSCDR90A160BL1NG?
MSCDR90A160BL1NG provides 2500 V RMS isolation between any terminal and the case for 1 minute at 50/60 Hz, as stated in Table 1-3 of the DS00004106A datasheet. This reinforced insulation rating satisfies safety requirements for industrial equipment per IEC 61800-5-1 and enables direct heatsink mounting without additional barrier materials in MSCDR90A160BL1NG-based designs.
Can MSCDR90A160BL1NG be mounted directly to a heatsink?
Yes, MSCDR90A160BL1NG is designed for direct heatsink mounting using M4 screws at 1.5–2.0 N·m torque, as specified in Table 1-3. Its isolated ceramic base eliminates the need for insulating pads or thermal interface materials, and the 0.468 °C/W RthJH value is measured under this direct-mount condition - a key thermal advantage confirmed for MSCDR90A160BL1NG in the official datasheet.
What is the forward voltage drop of MSCDR90A160BL1NG at rated current?
At 33 A and 25°C, MSCDR90A160BL1NG exhibits a typical forward voltage of 1.0 V (max 1.21 V); at 125°C, it drops to 0.9 V typical. The on-state voltage VT is specified at ≤0.83 V under switching conditions, and on-state slope resistance rT is 4.9 mΩ - all values measured per the test conditions defined for MSCDR90A160BL1NG in Table 1-2 of DS00004106A.
