Device Name: Silicon Diode Model Name: YG963S6 R
Specification number: MS5D1437

Scope This specification specifies the ratings and test requirements for Fuji silicon diodes.
YG963S6R type applied power factor correction circuit (current continuous mode) This diode is a product that optimizes diode characteristics for power factor correction circuits.
Although there is a relationship that trades off both VF and TRR, shortening TRR can suppress the total loss of the power factor correction circuit.

Precautions Although Fuji Electric continues to improve product quality and reliability, semiconductor products may malfunction when using Fuji Electric.
Please take appropriate safety measures for your company's semiconductor products. Measures to prevent equipment from causing personal injury, fire or other problems If any one product fails, it is recommended that your design is fail, safe, flame retardant, and trouble free.
・The products described in this specification are used in the following electronic equipment and electrical equipment with normal reliability requirements.
・Computers・OA equipment・Communication equipment (terminal equipment)
・Measuring equipment・Machine tools・AV equipment・Household appliances・Personal equipment・Industrial robots
These products are among the devices listed below, first check the system structure and required reliability.
Transportation equipment (cars, trains, ships, etc.)
・Trunk network equipment ・Traffic signal control equipment ・Gas alarms, automatic circuit breakers for leaking gas ・Subsea repeater equipment For equipment requiring strict reliability, such as (but not limited to: Aerospace Equipment Warning ・Diodes should be used at absolute maximum ratings (VLtage, current, temperature, etc.) Diodes may be damaged if used beyond their ratings.
Equipment containing diodes should have adequate fuses or protection to prevent secondary damage to the equipment.
・Diodes are used within their reliability and life span under certain environments or conditions.
If used with a certain reliability, the diode may fail before the target life of the product.
condition.
・You must design at the specified maximum ratings (voltage, current, temperature, etc.) to prevent possible malfunction or damage to the device.
・Consider not only the possible temperature rise of the joint and the housing, but also the boot.
Do not touch the leads or package of the diode directly during or during power-up.
When operating, avoid electric shock and burns.

・The diode is made of non-combustible material, but may emit smoke if the diode fails.
Operating the diode near any flammable location or material may also cause the diode to emit smoke or flames when it becomes hotter while operating.
Design arrangements to prevent the spread of fire.
・Diodes should not be used in environments with acids, organic substances, or corrosive gases (hydrogen sulfide, sulfurous acid gas)
・Diodes should not be used in irradiated fields because they are not radiation-proof.
Installation soldering involves temperatures exceeding the storage temperature rating of the equipment.
To avoid equipment damage and ensure reliability, please adhere to quality assurance standards.
・Solder temperature and time (through-hole package)
Welding duration temperature
260 ±5℃10±1s
350 ±10°C 3.0±0.5 seconds ・The immersion depth of lead should basically reach the lead plug and distance.
Maximum 1.5mm from the device.
• When flow soldering, take care to avoid immersing the package in the solder bath.
Please refer to the following torque references when installing the device on the heatsink. Excessive torque applied to the mounting screws can damage the device, while weak torque can increase thermal resistance, both of which can damage the device.
Table 1: Recommended tightening torques Recommended tightening for packaged screws ・The flatness of the heat sink should be within ±50μm, and the roughness should be within 10μm.
At the same time, keep the tightening torque within the limits of this specification.
Improper handling can lead to isolation failures, leading to major accidents.
・We recommend using a thermal compound to optimize heat radiation efficiency, it is important to apply the compound evenly and eliminate any airborne VIOS.
Storage Parts Diodes must be stored in an environment with a standard temperature of 5-35°C and a relative humidity of 45°C.
to 75%. A humidifier may be required if the storage area is very dry. In this case, use only deionized or boiled water, as the chlorine in the tap water may corrode the wires.
・Diodes should not be subjected to rapid changes in temperature to avoid condensation.
on the surface of the diode. Therefore, store the diode in a place with a high temperature.
Hold on.
・Diodes should not be stacked on top of each other, as this may cause excessive external force on the case.
• Diodes should not be stored with raw lead terminals. May rust. Causes pre-folded connections to fail later in processing.
・Diodes should be stored in an antistatic container or transport bag.
