Product details
Overview
MBR1635 from Taiwan Semiconductor is a 16A, 35V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.63 V at 16 A, 25°C), high surge current capability (150 A), and AEC-Q101 qualification option. It serves as a primary output rectifier in high-efficiency DC/DC converters and SMPS for automotive and industrial power supplies.
For engineers reviewing the MBR1635 datasheet, MBR1635 pinout, MBR1635 application, or MBR1635 equivalent, key selection criteria include its 35 V repetitive peak reverse voltage, 150°C maximum junction temperature, thermal resistance of 3°C/W (junction-to-case), and compatibility with lead-free reflow soldering per J-STD-002.
Technical Context
The MBR1635 uses a single-die Schottky structure optimized for low conduction loss and fast switching, with no minority-carrier storage delay. Its guard ring design enhances ruggedness against transient overvoltage events, and it meets JESD201 Class 2 whisker resistance requirements.
Thermally, the device relies on case-mounted heatsinking via its TO-220AC package, delivering 3°C/W junction-to-case thermal resistance. Reverse leakage remains ≤500 µA at 25°C and ≤15 mA at 125°C under rated 35 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF | 16 A continuous forward current - supports high-current output stages without forced air cooling |
| VRRM | 35 V repetitive peak reverse voltage - suitable for 24 V system-derived secondary-side rectification |
| VF @ 16 A, 25°C | 0.63 V max - reduces conduction loss to ~10 W at full load, improving efficiency in compact SMPS |
| IFSM | 150 A non-repetitive surge current - withstands inrush and fault transients in adapter and converter designs |
| RθJC | 3°C/W - enables predictable thermal design when mounted to heatsink with standard torque (0.56 N·m) |
| TJ max | 150°C - allows operation in under-hood automotive environments and sealed industrial enclosures |
| IR @ 35 V, 25°C | 500 µA max - minimizes standby power loss in energy-sensitive applications |
Pinout & Package
TO-220AC package: 3-terminal through-hole outline with isolated tab (cathode-connected), matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to transformer secondary or switch node; requires low-inductance layout to minimize ringing |
| Cathode | Output current terminal | Electrically tied to metal tab; must be insulated from chassis unless used as heatsink return path |
| Tab (Cathode) | Thermal & electrical cathode connection | Primary heat dissipation path; mounting torque limited to 0.56 N·m to avoid die fracture |

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-MBR1635CT | TO-220AB dual common-cathode configuration; 0.65 V VF (max) at 16 A, 25°C; same VRRM and IFSM | Requires dual-output or parallel-path layout; not single-anode/single-cathode drop-in | Select when dual-output rectification or redundancy is needed; verify PCB pad compatibility |
| ON Semiconductor MBR1635CT | TO-220AB package; 0.67 V VF (max); AEC-Q101 qualified only in "G" suffix variant; 3.5°C/W RθJC | Slightly higher thermal resistance and VF reduce efficiency margin in thermally constrained designs | Prefer for legacy ON-design ecosystems; confirm qualification status matches automotive program requirements |
Compared with MBR1635, VS-MBR1635CT offers dual-diode integration but demands layout revision, while MBR1635CT trades 0.04 V higher VF and +0.5°C/W thermal resistance for cross-supplier sourcing flexibility-neither is pin-compatible without footprint adjustment.

FAQ
What is the maximum junction temperature rating for the MBR1635?
The MBR1635 has a maximum junction temperature (TJ max) of +150°C, enabling reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 85°C. This rating is validated under specified thermal conditions with proper heatsinking and mounting torque applied to the TO-220AC tab.
Is the MBR1635 pin-compatible with other devices in the MBR16xx family?
No-the MBR1635 shares the TO-220AC package and 3-pin single-die configuration with all MBR16xx variants (e.g., MBR1645, MBR16150), but voltage ratings differ. Pinout is identical across the family, though forward voltage and leakage vary significantly with VRRM; substituting without circuit validation risks overvoltage failure or excessive loss.
Does the MBR1635 require a heatsink in typical 16 A operation?
Yes-while the MBR1635 delivers 3°C/W junction-to-case thermal resistance, dissipating ~10 W at full 16 A load (based on 0.63 V VF) necessitates a heatsink to maintain TJ ≤150°C. Without external heatsinking, case temperature would exceed safe limits even at moderate ambient temperatures.
What does the "H" suffix mean in MBR1635H ordering code?
The "H" suffix in MBR1635H indicates full AEC-Q101 qualification, including stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life. Standard MBR1635 lacks this certification and is intended for industrial or consumer applications where automotive-grade reliability is not mandated.
How does the guard ring in the MBR1635 improve system-level reliability?
The guard ring in the MBR1635 suppresses edge breakdown during fast voltage transients, allowing the device to sustain dv/dt rates up to 10,000 V/µs without avalanche failure. This protects downstream circuitry in noisy switching environments such as motor drives and automotive alternator rectification, reducing field failure risk.
