Product details
Overview
MBR1535CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in TO-220AB package, rated for 15A average forward current, 35V repetitive peak reverse voltage, and 150A surge current. It delivers low forward voltage (0.84V at 15A, 25°C) and operates up to 150°C junction temperature, enabling high-efficiency power conversion in automotive-grade DC/DC converters.
For engineers reviewing the MBR1535CTH datasheet, MBR1535CTH pinout, MBR1535CTH application, or MBR1535CTH equivalent, key selection criteria include its AEC-Q101 qualification, 1.5°C/W junction-to-case thermal resistance, guard ring overvoltage protection, and compatibility with high-surge, low-loss switching power supplies requiring RoHS- and halogen-free compliance.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220AB thermally optimized package, sharing a common cathode configuration (CT). Its 10,000 V/μs critical dv/dt rating supports fast-switching topologies without parasitic turn-on.
The dual-die structure enables balanced current sharing in center-tapped or parallel-output rectification schemes, while the guard ring design enhances ruggedness against transient overvoltage events typical in automotive load-dump conditions.

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-MBR1535CTH | Identical electrical specs and TO-220AB package; AEC-Q101 qualified per Vishay's QV-101 program | Same automotive and industrial use cases; minor differences in date-code marking and lead finish thickness | Select when dual-source assurance or alternate logistics chain is required |
| ON Semiconductor MBR1535CTG | Non-AEC-Q101 version; otherwise matches VF, IFSM, and RθJC; RoHS-compliant but not halogen-free certified | Suitable for commercial/industrial SMPS where automotive qualification is not mandated | Choose for cost-sensitive non-automotive designs with identical thermal and electrical needs |
Compared with MBR1535CTH, VS-MBR1535CTH offers drop-in logistics redundancy, while MBR1535CTG provides a lower-cost alternative where AEC-Q101 and halogen-free compliance are unnecessary-enabling trade-offs between qualification rigor and procurement flexibility.

FAQ
What does the "H" suffix in MBR1535CTH signify?
The "H" suffix in MBR1535CTH indicates full AEC-Q101 qualification per the latest revision, including stress testing for temperature cycling, humidity bias, and mechanical shock. This certification confirms suitability for automotive powertrain and chassis applications. MBR1535CTH also meets RoHS and halogen-free requirements per IEC 61249-2-21. The base part MBR1535CT lacks this qualification.
Is MBR1535CTH a single diode or dual-diode device?
MBR1535CTH is a dual-die Schottky rectifier with a common-cathode (CT) configuration: two independent anodes (Leads 1 and 2) share one cathode (the metal tab). This structure supports center-tapped transformer rectification or independent dual-output designs. Pinout verification confirms Lead 1 = Anode 1, Lead 2 = Anode 2, Tab = Common Cathode.
What is the maximum junction temperature and thermal resistance of MBR1535CTH?
MBR1535CTH has a maximum junction temperature (TJ max) of 150°C and a junction-to-case thermal resistance (RθJC) of 1.5°C/W. These values are measured under standard test conditions and enable reliable operation in high-ambient environments when mounted to an appropriately sized heatsink. RθJA is 10°C/W without heatsink, confirming necessity of thermal interface design.
Does MBR1535CTH have guard ring protection, and why does it matter?
Yes, MBR1535CTH incorporates a guard ring structure around each Schottky junction to suppress edge avalanche and improve voltage standoff stability under transient overvoltage. This feature enhances ruggedness during load-dump events in automotive 12V/48V systems and prevents premature failure during fast dv/dt switching-critical for reliability in SMPS and DC/DC converters.
How does the forward voltage of MBR1535CTH compare at different temperatures and currents?
At 15A and 25°C, MBR1535CTH exhibits VF = 0.84V; at 15A and 125°C, VF drops to 0.72V due to Schottky's negative temperature coefficient. At 7.5A and 25°C, VF is unspecified but ≤0.75V per family data. This behavior reduces conduction loss at elevated temperatures-unlike silicon diodes-and improves thermal stability in high-power density designs using MBR1535CTH.
