| RH129 6.9V Precision Reference DESCRIPTIO ABSOLUTE AXI U RATI GS The RH129 precision reference features excellent stability over a wide range of voltage, temperature and operating current conditions. The device achieves low dynamic impedance by incorporating a high gain shunt regulator around the Zener. The excellent noise performance of the device is achieved by using a buried Zener design which eliminates surface noise usually associated with ordinary Zeners. The wafer lots are processed to LTC's in-house Class S flow to yield circuits usable in stringent military applications. Reverse Breakdown Current ................................ 30mA Forward Current..................................................... 2mA Operating Temperature Range ............. - 55C to 125C Storage Temperature Range ................. - 65C to 150C Lead Temperature (Soldering, 10 sec).................. 300C , LTC and LT are registered trademarks of Linear Technology Corporation.

TABLE 2: ELECTRICAL TEST REQUIRE E TS MIL-STD-883 TEST REQUIREMENTS Final Electrical Test Requirements (Method 5004) Group A Test Requirements (Method 5005) Group B and D for Class S and Group C and D for Class B End Point Electrical Parameters (Method 5005) * PDA Applies to subgroup 1. See PDA Test Notes. SUBGROUP 1*, 2, 3 1, 2, 3 1 PDA Test Notes: The PDA is specified as 5% based on failures from group A, subgroup 1, tests after cooldown as the final electrical test in accordance with method 5004 of MIL-STD-883. The verified failures of group A, subgroup 1, after burn-in divided by the total number of devices submitted for burn-in in that lot shall be used to determine the percent for the lot. Linear Technology Corporation reserves the right to test to tighter limits than those given.
