1N5334Be3 1N5388Be3 (D0-201AE Package) Compliant Silicon 5 Watt Zener Diodes DESCRIPTION The 1N5334Be3 through IN5388Be3 JEDEC registered series of axial-leaded 5.0 watt Zeners provides a voltage selection of 3.6 V to 200 V with different tolerances as indentified by a suffix letter on a part number. These plastic encapsulated Zeners have a moisture classification of level 1 with no dry pack required. They may be operated at high maximum dc currents with adequate heat sinking due to their comparatively low thermal resistance design. DO-201AE comes in tape and reel only, TR7 and TR13.

See PART NOMENCLATURE 1N5336 B e3 Type number (see Electrical RoHS Compliant Characteristics table) Tolerance A = 10% B = 5% C = 2% SYMBOLS & DEFINITIONS Symbol Definition Temperature Coefficient of Regulator Voltage: The change in regulator voltage divided by the change in temperature VZ that caused it expressed in %/C or mV/C. I Reverse Current: The dc current flowing from the external circuit into the cathode terminal at the specified voltage V . R R I , I , I Regulator Current: The dc regulator current (I ), at a specified test point (I ), near breakdown knee (I ). Z ZT ZK Z ZT ZK Reverse Surge Current, Nonrepetitive Peak: The peak reverse current in the breakdown region including all I ZSM nonrepetitive transient currents but excluding all repetitive transients (also known as maximum Zener surge current). P Steady-State Power Dissipation: The dc power resulting from the product of V x I . D Z Z V Reverse Voltage: A positive dc cathode-anode voltage below the breakdown region. R V Zener Voltage: The Zener voltage the device will exhibit at a specified current (I ) in its breakdown region. Z Z Regulator Impedance: The small signal impedance of the diode when biased to operate in its breakdown region with Z or Z Z ZK I applied at I or I respectively. This has also been known as Zener or dynamic impedance (Z or Z ). ZT Z ZK ZT ZK RF01117, Rev. B (9/23/13) 2013 Microsemi Corporation Page 2 of 5
