ZENER DIODES
RD4.7FM to RD51FM
1 W PLANAR TYPE 2-PIN POWER MINI-MOLD
ZENER DIODES
The RD4.7FM to RD51FM are zener diodes with an allowable
dissipation of 1 W and a planar type 2-pin power mini-mold.
PACKAGE DRAWING (UNIT: mm)
FEATURES
• This diode is ideal for high density mounting due to about 65%
of mounting area in comparison with the conventional 3-pin
power mini-mold RD[ ]P.
• This diode realizes the 2-pin structured area mounting by
specifying the zener voltage classifications confirming to the
conventional RD[ ]P.
QUALITY GRADES
• Standard
Please refer to “Quality Grades on NEC Semiconductor
Devices” (Document No. C11531E) published by NEC
Corporation to know the specification of quality grade on
the devices and its recommended applications.
APPLICATIONS
• Surge absorption circuit
• Zener voltage and constant-current circuit
• Waveform clipper circuit and limiter circuit

Notes 1.
The zener voltage (V
Z
) is tested for 40 ms after power ON.
2.
The operation resistance (Z
Z
) is tested by superimposing a micro AC on the standard current (I
