Product details
Overview
MBRS1635H from Taiwan Semiconductor is a 16A, 35V Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring low forward voltage (0.63 V at 16 A, 25°C), AEC-Q101 qualification, and 150 A surge capability. It serves as a freewheeling or reverse-battery protection diode in automotive DC/DC converters and low-voltage inverters.
For engineers reviewing the MBRS1635H datasheet, MBRS1635H pinout, MBRS1635H application, or MBRS1635H equivalent, key selection criteria include its 35 V repetitive peak reverse voltage, 1.5 °C/W junction-to-case thermal resistance, 150°C max junction temperature, and TO-263AB mechanical compatibility with high-power surface-mount layouts.
Technical Context
This Schottky rectifier uses a single-die construction optimized for low conduction loss and fast switching in high-frequency power conversion. Its guard ring structure enhances overvoltage ruggedness, while the matte tin-plated leads ensure reliable solderability per J-STD-002.
Designed for automotive-grade reliability, MBRS1635H operates across –55°C to +150°C junction range and meets moisture sensitivity level 1 (J-STD-020). Its 500 µA max reverse leakage at 35 V and 25°C supports stable blocking in battery-protection circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16CTQ030PBF | 30 V VRRM, 16 A IF, TO-220AC package, no AEC-Q101 qualification | Not suitable for automotive under-hood use; limited to industrial/commercial DC/DC | Select when cost or legacy TO-220 footprint is prioritized over automotive compliance |
| ON Semiconductor MBR1635CT | 35 V VRRM, dual common-cathode configuration, TO-220AB package, AEC-Q101 qualified | Requires dual-diode layout; unsuitable for single-diode freewheeling or reverse-battery roles | Choose only if dual-output rectification or existing dual-D2PAK-compatible board reuse is required |
Compared with VS-16CTQ030PBF and MBR1635CT, MBRS1635H uniquely combines AEC-Q101 qualification, TO-263AB thermal performance (1.5 °C/W), and single-diode simplicity-making it optimal for space-constrained, high-reliability automotive power rails where layout efficiency and qualification alignment are critical.

FAQ
What is the maximum junction temperature rating for MBRS1635H?
The MBRS1635H has a maximum junction temperature (TJ MAX) of +150°C, validated per AEC-Q101 stress testing. This rating allows direct use in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains TJ ≤ 150°C using the specified RθJC of 1.5 °C/W and adequate PCB copper area. The MBRS1635H datasheet confirms this limit applies across its full operating life.
Is MBRS1635H pin-compatible with other parts in the MBRS16xH series?
Yes, all MBRS16xH variants-including MBRS1635H, MBRS1645H, and MBRS16150H-share identical TO-263AB (D2PAK) package dimensions, pinout, and terminal assignments. The "x" denotes only the VRRM rating (35 V to 150 V); mechanical and layout compatibility is fully maintained across the series, enabling voltage-scaling without PCB revision.
Does MBRS1635H require special handling for moisture sensitivity?
No-MBRS1635H is rated Moisture Sensitivity Level 1 (MSL-1) per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without baking. This eliminates pre-conditioning steps in SMT lines and supports just-in-time manufacturing. The MBRS1635H's MSL-1 status is verified in TSC's official qualification report A2103.
What is the forward voltage of MBRS1635H at elevated temperature?
At 16 A forward current and 125°C junction temperature, MBRS1635H exhibits a typical forward voltage of 0.57 V (max not specified, but typ. decreases with temperature). This lower VF at high TJ improves system efficiency during thermal stress conditions, such as sustained high-load operation in automotive DC/DC converters. The MBRS1635H electrical specifications table explicitly lists this 0.57 V value under TJ = 125°C test conditions.
Can MBRS1635H be used in reverse battery protection without additional components?
Yes-MBRS1635H is routinely deployed as a standalone series protection diode in reverse battery circuits due to its 35 V VRRM (sufficient for 24 V systems with transients), 150 A IFSM (handles jump-start surges), and low VF (minimizing voltage drop). No external TVS or fusing is required for basic protection, though system-level fault analysis should confirm worst-case clamping behavior. The MBRS1635H application notes validate this use case in car lighting and ECU power inputs.
