Product details
Overview
MBR1635HC0G from Taiwan Semiconductor is a 16A, 35V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.63V max forward voltage at 16A/25°C, 150A surge current capability, and guard ring overvoltage protection for automotive-grade power conversion.
For engineers reviewing the MBR1635HC0G datasheet, MBR1635HC0G pinout, MBR1635HC0G application, or MBR1635HC0G equivalent, this device serves as a high-efficiency, low-loss output rectifier in compact 12–24V DC-DC converters and industrial SMPS where thermal performance (RθJC = 3°C/W) and reliability under repetitive surge stress are critical selection criteria.
Technical Context
This single-die Schottky rectifier operates with unidirectional conduction and zero minority-carrier storage, enabling fast switching with negligible reverse recovery charge. Its guard ring structure enhances ruggedness against transient overvoltage events common in automotive load-dump conditions.
The device sustains 150A non-repetitive surge current (8.3ms half-sine) and maintains stable reverse leakage (<500µA at 25°C, <15mA at 125°C) across its full -55°C to +150°C junction temperature range, supporting operation in thermally constrained enclosures.
Key Specifications

| Peak Reverse Voltage (VRRM) | 35 V - rated for 12V automotive and industrial 24V bus applications with margin |
| Forward Voltage (VF) | 0.63 V max @ 16A, 25°C - reduces conduction loss by ~30% vs. comparable Si diodes |
| Surge Current (IFSM) | 150 A @ 8.3ms - withstands inrush and fault transients in offline SMPS and adapters |
| Junction-to-Case Thermal Resistance | 3 °C/W - enables direct heatsink mounting for thermal management in space-constrained designs |
| Operating Junction Temp | -55°C to +150°C - qualified for under-hood automotive environments per AEC-Q101 |
| Reverse Leakage (IR) | 500 µA max @ 35V, 25°C - ensures low standby power loss in always-on systems |

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; 0.65V VF @ 16A; not AEC-Q101 qualified | Requires PCB layout change due to dual-diode pinout; unsuitable for automotive qualification | Select only for cost-sensitive industrial adapters where dual-diode topology matches existing design |
| ON Semiconductor MBR1635CT | TO-220AB package; 0.64V VF @ 16A; AEC-Q101 available only in MBR1635CT-H variant | Same pinout but different marking and thermal resistance (RθJC = 3.5°C/W); requires revalidation of heatsink interface | Consider when sourcing flexibility is needed across multiple franchised distributors, with verification of H-grade availability |
Compared with VS-MBR1635CT and MBR1635CT, the MBR1635HC0G provides guaranteed AEC-Q101 qualification, lower RθJC, and verified green/halogen-free compliance out-of-box-critical for Tier-1 automotive BOMs where audit traceability and material declarations are mandatory.

FAQ
What does the 'H' and 'C0G' suffix indicate in MBR1635HC0G?
The 'H' denotes AEC-Q101 qualification per automotive reliability standards, while 'C0G' specifies green (halogen-free) compound per IEC 61249-2-21 and RoHS compliance. This exact marking confirms MBR1635HC0G meets both automotive stress testing and environmental regulatory requirements without requiring additional validation.
Is MBR1635HC0G pin-compatible with standard TO-220AC rectifiers?
Yes, MBR1635HC0G uses the industry-standard TO-220AC footprint with anode on lead 1, cathode on lead 2, and isolated tab. It replaces generic 16A/35V Schottky rectifiers in existing layouts without modification, provided thermal interface and mounting torque (≤0.56 N·m) comply with TSC mechanical specifications.
What is the maximum allowable case temperature for MBR1635HC0G during continuous operation?
MBR1635HC0G supports continuous operation up to +150°C junction temperature. With RθJC = 3°C/W, the case temperature must remain ≤140°C when dissipating 3.3W (e.g., 16A × 0.63V) to maintain safe margin-achievable using a 15°C/W heatsink with 25°C ambient.
Does MBR1635HC0G require derating at elevated ambient temperatures?
Yes, MBR1635HC0G forward current must be linearly derated above 75°C case temperature per its derating curve. At 100°C case, rated IF drops to ~12A; at 125°C, it falls to ~8A. Full 16A operation is only valid below 75°C case temperature with adequate heatsinking.
How does the guard ring structure in MBR1635HC0G improve system-level reliability?
The integrated guard ring in MBR1635HC0G prevents edge breakdown during voltage transients such as ISO 7637-2 Pulse 5a (load dump), allowing the device to clamp without catastrophic failure. This extends field life in automotive ECUs and industrial controls where unprotected rectifiers commonly fail prematurely under surge stress.
