Product details
Overview
MBRS1535CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 15 A average forward current, 35 V repetitive peak reverse voltage, and 150 A surge current, with 0.84 V forward voltage at 15 A and 25°C. It serves as a high-efficiency freewheeling or reverse-battery-protection diode in automotive lighting and DC/DC converters.
For engineers reviewing the MBRS1535CTH datasheet, MBRS1535CTH pinout, MBRS1535CTH application, or MBRS1535CTH equivalent, key selection criteria include its AEC-Q101 qualification, 2 °C/W junction-to-case thermal resistance, 150°C max junction temperature, and guard-ring-enabled overvoltage protection-critical for under-hood automotive power stages.
Technical Context
This dual-die surface-mount rectifier integrates two independent Schottky diodes in a single TO-263AB thermally optimized package. Its low VF (0.72 V at 15 A, 125°C) and high dv/dt rating (10,000 V/μs) support fast-switching topologies in high-frequency DC/DC conversion.
The device features a guard ring structure for enhanced transient overvoltage immunity and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity-enabling robust automated assembly without baking.
Key Specifications

| RθJC | 2 °C/W - allows direct heatsinking to PCB copper or external metal slug for >90% thermal efficiency |
| TJ max | 150 °C - enables operation in under-hood environments up to 125°C ambient with derating |
| IR @ 35 V, 125°C | 15 mA - limits leakage-induced standby power loss in always-on vehicle modules |

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-15CTQ030 | Single-diode TO-220AC; 30 V VRRM, 0.52 V VF @ 7.5 A, 20 A IFSM | Lacks AEC-Q101 qualification and dual-die integration; lower surge rating | Use only in non-automotive, lower-reliability 3.3–5 V logic supplies where space permits discrete mounting |
| ON Semiconductor MBR1535CT | Same TO-263AB package, identical 35 V/15 A ratings, but not AEC-Q101 qualified; VF slightly higher (0.87 V @ 15 A) | No automotive qualification; limited to industrial or consumer DC/DC where extended temperature validation is not required | Select when AEC-Q101 is not mandated and cost is primary; verify thermal margin due to higher VF |
Compared with VS-15CTQ030 and MBR1535CT, MBRS1535CTH delivers automotive-grade reliability via AEC-Q101, superior surge capability (150 A vs. 20 A or 120 A), and dual-diode integration-making it the only choice for space-constrained, high-surge automotive power stages requiring zero-bake assembly.

FAQ
What is the maximum junction temperature rating for MBRS1535CTH?
The MBRS1535CTH has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 stress testing. This allows operation in under-hood automotive environments up to 125°C ambient when properly heatsinked, with derating applied above 100°C case temperature per the forward current derating curve in the datasheet.
Is MBRS1535CTH pin-compatible with other parts in the MBRS15xxCTH family?
Yes, all MBRS15xxCTH variants-including MBRS1535CTH, MBRS1545CTH, and MBRS15150CTH-share identical TO-263AB (D2PAK) package dimensions, pinout, and terminal assignments. Voltage rating differences (35 V to 150 V) do not affect mechanical or electrical interface compatibility.
Does MBRS1535CTH require baking before reflow soldering?
No, MBRS1535CTH is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without pre-baking-reducing process steps and avoiding thermal stress on the device or PCB.
What is the typical forward voltage of MBRS1535CTH at full rated current?
The typical forward voltage of MBRS1535CTH is 0.84 V at 15 A and 25°C, and 0.72 V at 15 A and 125°C. These values are measured per diode under pulsed conditions and reflect actual conduction loss in high-temperature automotive operating conditions.
How does the guard ring in MBRS1535CTH improve reliability?
The guard ring in MBRS1535CTH prevents premature edge breakdown during repetitive reverse-bias transients-such as those seen in automotive load dump or alternator ripple-by redistributing electric field concentration. This extends operational lifetime in harsh 12 V battery systems and is verified through AEC-Q101 transient overvoltage testing.
