## **Absolute Maximum Ratings**[(1)] 

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted. 

|**Note:**<br>1. These ratings are limiting values above which the serviceability of the diode may be impaired.<br>**Thermal Characteristics**<br>**Symbol**<br>**Parameter**<br>**Value**<br>**Unit**<br>VRRM<br>Maximum Repetitive Reverse Voltage<br>100<br>V<br>IO<br>Average Rectified Forward Current<br>200<br>mA<br>IF<br>DC Forward Current<br>300<br>mA<br>If<br>Recurrent Peak Forward Current<br>400<br>mA<br>IFSM<br>Non-repetitive Peak Forward Surge Current<br>Pulse Width = 1.0 s<br>1.0<br>A<br>Pulse Width = 1.0μs<br>4.0<br>A<br>TSTG<br>Storage Temperature Range<br>-65 to +200<br>°C<br>TJ<br>Operating Junction Temperature Range<br>-55 to +175<br>°C<br>**Symbol**<br>**Parameter**<br>**Max.**<br>**Unit**<br>**1N/FDLL 914/A/B / 916/A/B / 4148 / 4448**<br>PD<br>Power Dissipation<br>500<br>mW<br>RθJA<br>Thermal Resistance, Junction-to-Ambient<br>300<br>°C/W<br>~~——=~~|

## **ANTI-COUNTERFEITING POLICY** 

Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support. 

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
