Radiation Hardened 2.5V Reference
IS-1009RH, IS-1009EH
Features
• Electrically screened to SMD # 5962-00523
• QML qualified per MIL-PRF-38535 requirements
• EH version acceptance tested to 50krad(Si) (LDR)
TM
The Star*Power Radiation Hardened IS-1009RH, IS-1009EH
are a 2.5V shunt regulator diode is designed to provide a stable
2.5V reference over a wide current range.
These devices are designed to maintain stability over the full
military temperature range and over time. The 0.2% reference
tolerance is achieved by on-chip trimming.
• Radiation environment
- High dose rate (50-300rad(Si)/s). . . . . . . . . . . 300 krad(Si)
- Low dose rate (0.01rad(Si)/s) . . . . . . . . . . . . . . 50krad(Si)
- Latch-up immune. . . . . . . . . . . . . . . . dielectrically isolated
An adjustment terminal is provided to allow for the calibration
of system errors. The use of this terminal to adjust the
reference voltage does not effect the temperature coefficient.

• Change in V vs. current (400µA to 10mA) . . . . . . . . . . .6mV
Z
Constructed with the Intersil dielectrically isolated EBHF
process, these devices are immune to Single Event Latch-up
and have been specifically designed to provide highly reliable
performance in harsh radiation environments.
• Change in V vs. temperature (-55°C to +125°C). . . . .15mV
Z
• Maximum reverse breakdown current . . . . . . . . . . . . . 20mA
• Device is tested with 10µF shunt capacitance connected
from V+ to V-, which provides optimum stability
Specifications for Rad Hard QML devices are controlled by the
Defense Logistics Agency Land and Maritime (DLA). The SMD
