Diode Data Sheet



Provides maximum ratings, electrical characteristics, mechanical data, graphs of parameters, etc. for electrical device in use.

Several parameters are seen in a data sheet for diodes:

Maximum ratings

i) VRRM: (Peak repetitive reverse voltage).

Maximum reverse peak voltage that can be applied repetitively across the diode.

ii) VR: (DC blocking voltage)

Maximum reverse dc voltage that can be applied across the diode.

iii) VRSM: (Nonrepetitive peak reverse voltage)

Maximum reverse peak value of nonrepetitive voltage that can be applied across diode.

iv) IO: (Average rectified forward current)

Maximum average value of a 60Hz rectified forward current.

v) IFSM: (Nonrepetitive peak surge current)

Maximum peak value of nonrepetitive (one cycle) forward surge current.

A graph for different temperatures is generally available.

vi) TA:

Ambient temperature.

vii) TJ:

Operating junction temperature range.

viii) Tstg:

Storage junction temperature range.

Electrical Characteristics

i) vF: Instantaneous voltage across the forward-biased diode when forward current is 1 A at 25oC. Shown generally shown by a graph.

ii) VF(avg): Maximum forward voltage drop averaged over a full cycle.

iii) IR: Maximum current when diode is reverse-biased.

iv) IR(avg): Maximum reverse current averaged over one cycle (when reverse-biased with an ac voltage).
