ESD761: VRWM and VBRF

ttd
Mastermind 8620 points
Part Number: ESD761

The data sheet has the following specifications
VRWM : +24V
VBRF : +25.5(min)

Which of the following applies between +24V and +25.5V: (1), (2), or (3)?
(1) Stand-off
(2) Breakdown
(3) Indeterminate

Best Regards,

ttd

    Hi ttd,

    The standoff voltage is the same as the working voltage (Vrwm) which is no higher than 24 V for this device.

    VRWM is defined as the maximum positive and negative voltage where current flowing through the diode does not exceed a certain amperage, typically low nA range.

    Once the voltage at the input exceeds the Vrwm it approaches the break down voltage (Vbr) where current flowing through the diode increases from nA to mA.

    For this device the breakdown is spec'd at a max of 35.5 V with 10mA flowing through the diode. 

    The breakdown voltage can vary within the given range of 25.5 V - 35.5 V however it will typically breakdown at about 33 V as shown in the TLP graph. 

    Regards,

    Sebastian
