1. General Information (Applicable to all Datasheets)

️· Product Type: Unidirectional Transient Voltage Suppressors. These protect circuits from voltage spikes and surges.
️· Suffixes:
- No suffix (e.g., 1N5661): 10% tolerance.
- Suffix "A" (e.g., 1N5661A): 5% tolerance. Military versions are also available with JAN, JANTX, or JANTXV prefixes.
️· Key Parameters & Definitions:
- VWM (Standoff Voltage): The maximum reverse voltage allowed without triggering conduction.
- V(BR) (Breakdown Voltage): The voltage at which the device starts to conduct heavily.
- VC (Maximum Clamping Voltage): The peak voltage across the device under specified surge conditions.
- IPP (Peak Pulse Current): The maximum current the device can handle during a surge.
- ID (Standby Current): The current flowing at the standoff voltage.
- I(BR) (Breakdown Current): The current used to measure the breakdown voltage.
️· Important Note: TVS diodes are typically selected based on their standoff voltage (VWM) which must be equal to or greater than the applied voltage.
️· Temperature Derating: There are derating curves to show how the device’s power handling capability decreases with increasing ambient temperature.
️· Datasheet Revision: Rev A, dated November 6, 2003
