{"product_id":"littelfuse-b61089qdr","title":"Littelfuse B61089QDR","description":"The SLIC chipset voltage reference may change as the on-hook\/off-hook line condition changes. Therefore, this component is referenced to the - VBAT so that its negative protection threshold follows this changing reference voltage level. This B610989QDR utilizes a transistor gain network so that a low 5 mA current level will activate the thyristor based portion of this protector component during negative events. This also allows an easier turn on during slow rising power fault events. For all positive disturbances, the fast switching diode connected to earth reference will provide the needed protection.B61089QDR - B61089QDR Series\u003cp\u003e\u003cstrong\u003eLittelfuse B61089QDR is now available from Williams Automation.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf you need a specific firmware version or series for this item, please call or email us with your request.
