Product details
Overview
MBRS2035CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 20A average forward current, 35V repetitive peak reverse voltage, and 150A surge current, with 0.65V max forward voltage at 10A/25°C-optimized for low-loss DC/DC conversion in automotive lighting and reverse battery protection circuits.
For engineers reviewing the MBRS2035CTH datasheet, MBRS2035CTH pinout, MBRS2035CTH application, or MBRS2035CTH equivalent, key selection criteria include its AEC-Q101 qualification, 1.5°C/W junction-to-case thermal resistance, guard ring–enabled overvoltage robustness, and moisture sensitivity level 1 compliance for high-reliability surface-mount assembly.
Technical Context
The MBRS2035CTH integrates two independent Schottky diodes in a single TO-263AB thermally enhanced package, sharing a common cathode configuration. Its low VF (≤0.65V @ 10A, 25°C) and high IFSM (150A) support efficient high-frequency switching in compact power stages.
Designed for automotive-grade reliability, it features a guard ring structure to suppress avalanche-induced failure under transient overvoltage, and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements-enabling direct reflow without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 20 A - supports continuous output current in 12V/24V automotive DC/DC converters without forced air cooling |
| VRRM | 35 V - withstands peak reverse transients up to 35V, suitable for 24V system reverse polarity protection |
| IFSM (8.3ms) | 150 A - handles cold-crank surges and load-dump events in vehicle electrical systems |
| VF (max @ 10A, 25°C) | 0.65 V - reduces conduction loss by >30% vs. standard silicon rectifiers at same current |
| RθJC | 1.5 °C/W - enables thermal design margin of ≥45°C rise at 20A with 1-in² 2-oz copper pad |
| TJ max | +150 °C - allows operation in under-hood environments with ambient up to +105°C |
| IR (max @ 35V, 25°C) | 100 µA - ensures minimal leakage in battery-sensing and always-on circuits |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, thermally optimized with exposed anode tab (pins 1 & 2 = anodes, pin 3 = common cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first Schottky diode; electrically isolated from Pin 2 but shares thermal path via common tab |
| Pin 2 | Anode 2 | Input terminal for second Schottky diode; enables dual-channel freewheeling or independent half-wave rectification |
| Pin 3 | Common Cathode | Shared output node; requires low-inductance layout to minimize switching noise in high-dI/dt applications |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature cycling, humidity bias, and mechanical shock per stress test plan-no derating required for under-hood use |
| Guard ring structure | Prevents edge breakdown during repetitive 35V reverse transients, extending lifetime beyond 10,000 hours at full rating |
| Moisture sensitivity level 1 | Zero bake requirement before SMT reflow; compatible with standard J-STD-020 profile without floor-life constraints |
| Matte tin-plated leads | Ensures solder joint reliability per J-STD-002B; eliminates intermetallic growth issues in lead-free assembly |

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-20CPQ035 | Same 35V VRRM, 20A IF, TO-263AB package; VF = 0.62V typ @ 10A, but not AEC-Q101 qualified | Lacks automotive qualification; unsuitable for safety-critical or OEM production without additional validation | Select only for industrial or consumer designs where AEC-Q101 is not mandated |
| ON Semiconductor MBR2035CT | Identical electrical specs and TO-263AB footprint; differs in marking code and internal die process-VF max 0.67V vs. 0.65V | Compatible in existing layouts; minor VF difference yields ~0.5W lower loss at 20A in thermal-limited designs | Drop-in alternative if Taiwan Semiconductor supply is constrained; verify date-code traceability for long-term BOM stability |
Compared with VS-20CPQ035 and MBR2035CT, the MBRS2035CTH delivers certified automotive reliability and marginally lower forward voltage-making it preferred for Tier-1 automotive subsystems where qualification and thermal efficiency are jointly critical.

FAQ
What is the maximum junction temperature rating for MBRS2035CTH?
The MBRS2035CTH has a maximum junction temperature (TJ max) of +150°C, validated per absolute maximum ratings in the official datasheet. This allows reliable operation in under-hood automotive environments where ambient temperatures reach +105°C, provided thermal design maintains junction temperature below this limit using the specified 1.5°C/W RθJC path.
Is MBRS2035CTH pin-compatible with other parts in the MBRS20xCTH family?
Yes, all MBRS20xCTH variants-including MBRS2035CTH, MBRS2045CTH, and MBRS20150CTH-share identical TO-263AB (D2PAK) package dimensions, pinout (pins 1 & 2 = anodes, pin 3 = common cathode), and thermal pad layout. Voltage rating differences do not affect mechanical or electrical compatibility.
Does MBRS2035CTH require baking before reflow soldering?
No, MBRS2035CTH is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into standard lead-free reflow profiles without pre-baking-a key advantage for high-throughput SMT lines.
What is the forward voltage specification for MBRS2035CTH at full rated current?
At 20A and 25°C junction temperature, the MBRS2035CTH has a maximum forward voltage (VF) of 0.84V per diode. At elevated temperature (125°C), VF rises to 0.72V max-demonstrating stable conduction characteristics across automotive operating ranges.
How does the guard ring feature improve reliability in MBRS2035CTH?
The guard ring in MBRS2035CTH suppresses premature edge breakdown during reverse-biased transients, enabling sustained operation at 35V VRRM even under repetitive overvoltage conditions. This extends device lifetime in automotive applications subject to load dump or alternator regulation spikes without requiring external TVS clamping.
