DESCRIPTION
These popular 1N457 – 1N459 series of JEDEC registered s witch ing/signal diodes are
metallurgically bonded. Th ese small low capac i tance diodes wit h ver y fast switching speeds
are hermetically sealed and bonded in to a double-plug DO-35 package. They may be u sed in
a var i ety of fast swit ching applicati ons . Microsemi also offers a variety of other
switching/signal diodes.

IF
Forward 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.
VF
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
VRWM
Working Peak Reverse Voltage: The maxim um peak voltage that can be applied over the operating tem perature range
excluding all transient voltages (ref JESD282-B). Also sometimes known as PIV.
VWM
Working Peak Voltage: The maximum peak voltage that can be applied over the operating temperature range. This is
also referred to as Standoff Voltage.
