Product details
Overview
VS-36MB05A from Infineon Technologies is a single-phase bridge rectifier module rated for 35 A average forward current (resistive/inductive load), 1600 V maximum repetitive reverse voltage (VRRM), and 1.14 V maximum forward voltage drop at 25 °C. It features electrically insulated case, UL E62320 approval, and is designed for general-purpose AC/DC conversion in industrial power supplies and instrumentation.
For engineers reviewing the VS-36MB05A datasheet, VS-36MB05A pinout, VS-36MB05A application, or VS-36MB05A equivalent, key selection criteria include its 35 A thermal current rating at 60 °C case temperature, 1.2 K/W junction-to-case thermal resistance, 2700 V RMS isolation voltage, and compatibility with push-on/wrap-around/solder terminal mounting.
Technical Context
The VS-36MB05A implements a full-wave single-phase bridge configuration using four silicon diodes in a compact, encapsulated package with electrically isolated metal baseplate. Its thermal design supports direct heatsink mounting via center-hole fixing and 2.0 Nm torque specification.
It operates across –40 °C to +150 °C junction temperature range and delivers stable rectification under capacitive, inductive, or resistive loads - with derated IO of 28 A for capacitive loads and validated I²t surge capability of 1130 A²s (10 ms, no voltage reapplied) at maximum junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO (Avg) | 35 A at TC = 60 °C - defines continuous DC output capability under standard thermal conditions |
| VRRM | 1600 V - maximum repetitive reverse voltage per diode; sets AC input voltage headroom |
| VFM | 1.14 V at TJ = 25 °C, IFM = π × IO - forward drop during peak conduction, directly impacts conduction loss |
| RthJC | 1.2 K/W - thermal resistance from junction to case; critical for heatsink sizing and thermal margin |
| VINS | 2700 V RMS - isolation voltage between baseplate and terminals; enables safe operation in grounded systems |
| IFSM (60 Hz) | 500 A - non-repetitive surge current handling for 8.3 ms; determines short-circuit robustness |
| TJ Range | –40 to +150 °C - operational junction temperature window; supports industrial ambient environments |
Pinout & Package
VS-36MB05A uses a molded, electrically insulated single-phase bridge package with three-way universal terminals (push-on, wrap-around, or solder). The metal baseplate serves as the common heatsink interface and provides electrical isolation from internal diodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal 1 | One leg of AC input; connects to line or phase conductor in single-phase supply |
| AC2 | AC Input Terminal 2 | Second leg of AC input; completes full-wave bridge input path |
| + (Anode Output) | Positive DC Output | Full-wave rectified positive output node; feeds downstream filter or regulator |
| – (Cathode Output) | Negative DC Output | Full-wave rectified negative output node; forms return path for DC load current |
Key Features
| Feature | Design Value |
|---|---|
| Universal terminal interface | Supports push-on, wrap-around, and solder connections - simplifies assembly across OEM and repair workflows |
| Electrically insulated case | 2700 V RMS isolation enables direct mounting on grounded heatsinks without additional insulation |
| High power/volume ratio | 35 A / 1600 V in compact footprint - reduces board space vs discrete diode solutions |

FAQ
What is the maximum average forward current rating for VS-36MB05A?
The VS-36MB05A is rated for 35 A average forward current (IO) at a case temperature of 60 °C with resistive or inductive loads. For capacitive loads, the rating is derated to 28 A. This value reflects continuous DC output capability under defined thermal conditions and must be applied with appropriate heatsinking to maintain TC ≤ 60 °C.
Does VS-36MB05A require electrical insulation when mounted to a heatsink?
No - VS-36MB05A features an electrically insulated metal baseplate rated for 2700 V RMS isolation. It can be directly mounted to a grounded heatsink without additional insulating pads or hardware, simplifying thermal design and reducing assembly cost.
What is the forward voltage drop specification for VS-36MB05A?
VS-36MB05A has a maximum forward voltage drop (VFM) of 1.14 V at TJ = 25 °C and instantaneous forward current equal to π × IO (i.e., ~110 A). This parameter directly determines conduction losses and thermal loading under nominal operating conditions.
Can VS-36MB05A be used in 230 VAC input applications?
Yes - with a 1600 V VRRM rating, VS-36MB05A provides ample margin for 230 VAC ±15% mains input (peak ≈ 380 V), including transient overvoltages and harmonic content. Its 500 A IFSM (60 Hz) further supports robust operation during line surges and inrush events.
What mounting torque is specified for VS-36MB05A?
The recommended mounting torque for VS-36MB05A is 2.0 Nm ±10% when securing the module to the heatsink. This ensures optimal thermal contact while avoiding mechanical stress on the encapsulated structure or terminal interfaces.
