SYMBOLS & DEFINITIONS

Symbol

Definition

IF

Forward Current: The forward current dc value, no alternating component.

IFSM

Maximum Forward Surge Current: The forward current, surge peak or rated forward surge current.

IO

Average Rectified Output Current: The Output Current averaged over a full cycle with a 50 Hz or 60 Hz sine-wave

input and a 180 degree conduction angle.

IR

Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.

trr

Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from

the forward direction to the reverse direction and a specified decay point after a peak reverse current occurs.

V F

Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.

V R

Reverse Voltage: The reverse voltage dc value, no alternating component.

V RRM

Repetitive Peak Reverse Voltage: The peak reverse voltage including all repetitive transient voltages but excluding all

non-repetitive transient voltages.

V RWM

Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range

excluding all transient voltages (ref JESD282-B). Also sometimes known as PIV.
