Microchip Technology

This series of high-current single-phase bridge rectifiers are constructed with hermetically sealed rectifiers with the same design and construction as used in military applications for the utmost in reliability. They can also be optionally obtained with formal military screened diodes that have been subjected to 100% screening and military qualified to MIL-PRF-19500/469 that are ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 10 Amp rated rectifier bridges with working peak reverse voltages from 200 to 600 volts for each leg use diodes that are hermetically sealed with voidless-glass construction using an internal "Category I" metallurgical bond. Microchip also offers numerous other rectifier products to meet higher and lower current ratings with various recovery time speed requirements including fast and ultrafast device types in both through-hole and surface mount packages.

The Microchip Technology Inc 47C04 EERAM is a 4Kbit SRAM with EEPROM Backup. The I2C EERAM Memory is a Low-Cost NVSRAM that Eliminates the Need for an External Battery to Retain Data. The device is organized as 512 x 8 bits and utilizes the I2C serial interface. The 47C04 provides infinite read and write cycles to the SRAM while the EEPROM cells provide high endurance non-volatile storage of Data. With an external capacitor, SRAM data is automatically transferred to the EEPROM upon power-loss. Data can also be transferred manually by using either the hardware store pin or by software control. Upon power-up, the EEPROM data is automatically recalled to the SRAM. Recall can also be initiated through software control. The unlimited endurance makes the EERAM useful in applications that need to constantly monitor or record data. The 47C04 EERAM has a 4.5-5.5V operating voltage range and is available in 8-lead SOIC, TSSOP and PDIP packages. The EERAM works from -40C to 125C and is automotive grade qualified.

The Microchip Technology Inc 47L04 EERAM is a 4Kbit SRAM with EEPROM Backup. The I2C EERAM Memory is a Low-Cost NVSRAM that Eliminates the Need for an External Battery to Retain Data.

With an external capacitor, SRAM data is automatically transferred to the EEPROM upon power-loss. Data can also be transferred manually by using either the hardware store pin or by software control. Upon power-up, the EEPROM data is automatically recalled to the SRAM. Recall can also be initiated through software control. The unlimited endurance makes the EERAM useful in applications that need to constantly monitor or record data. The 47L04 EERAM has a 2.7-3.6V operating voltage range and is available in 8-lead SOIC, TSSOP and PDIP packages. The EERAM works from -40C to 125C and is automotive grade qualified.

The Microchip Technology Inc 47C16 EERAM is a 16Kbit SRAM with EEPROM Backup. The I2C EERAM Memory is a Low-Cost NVSRAM that Eliminates the Need for an External Battery to Retain Data. The device is organized as 2048 x 8 bits and utilizes the I2C serial interface. The 47C16 provides infinite read and write cycles to the SRAM while the EEPROM cells provide high endurance non-volatile storage of Data. With an external capacitor, SRAM data is automatically transferred to the EEPROM upon power-loss. Data can also be transferred manually by using either the hardware store pin or by software control. Upon power-up, the EEPROM data is automatically recalled to the SRAM. Recall can also be initiated through software control.

The 47C16 EERAM has a 4.5-5.5V operating voltage range and is available in 8-lead SOIC, TSSOP and PDIP packages. The EERAM works from -40C to +125C and is automotive grade qualified.

This series of high-current three-phase bridge rectifiers are constructed with hermetically sealed rectifiers built with the same design and construction techniques used in military applications for the upmost in reliability. These include voidless glass encapsulation and internal "Category 1" metallurgical bonds. They can optionally be purchased built with diodes that have been screened and mil-qualified to MIL-PRF-19500/483, making them ideal for applications where failure cannot be tolerated. These 25A rectifier bridges are available with working peak reverse voltage ratings of 200, 400, 600, or 800 V per leg
